N and a popular Chinese online store site in the description of a 12-volt water pump for the arrangement of fountains in the aquariums and country decorative mini-pools, we accidentally got on the eyes of a curious feedback from the Russian car owner, who applied this pump as an oil pumping system from the engine crankcase of his Fiat BRAVO!

The pump is designed for water, but a cunning citizen quickly realized that if you connect thin hoses and wires with a pair of "crocodiles" to power the device from a car battery, then the superb budget system for replacing the engine in the engine or gearbox! Related Pumps included with tubes and wires, designated, as specialized for pumping oil, stand in a Chinese online store from 2,000 rubles and more expensive, so that in this case it turns out a supercommunication option.

Actually, this decision is definitely not everyone - after all, what kind of gas in the pumping of the oil through the dipstick, if you still need to climb a car under the "belly" in order to unscrew the filter? However, machines in which the engine modification and the layout of the subcontrol space allows without much difficulty to unscrew the oil filter from above from under the hood, quite a lot: from grants to focus and from the "Volgovsky" old man Elements in glasses. Well, the unicumes of a kind - "Volkswagen" motors CAXA, CFNA, etc., in which the filter is almost vertically at the level of the block head, as a result of which it is even easier to unscrew it than to add water to the washer tank. Plus extracted the filter is completely clean and empty, without a drop of oil.

Check how convenient and implemented the proposed solution? Our goal is to determine the effectiveness of the pump, is it sufficient for performance when working with thick butter instead of water, and most importantly - how durable its design is? After all, if in the interval between the replacements of oil, the remnants of testing in the pump will destroy its plastic from the inside, then there is no point in such a "Harobland" ...

Pump design

The design of the pump surprised and grieved. There was a feeling that a cunning citizen who threw the idea of \u200b\u200bmass, did not disassemble him before use as an "oil loss" ... The principle of work of the Chinese craft is practically the same as that of the high pressure pumps "A la Karcher", but not on The basis of metal piston plungers, and based on silicone elastic membranes. An eccentric is installed on the shaft of the electric motor, which, rotating, alternately raises the swing membranes located in a circle. The one-sided course of fluid provides check valves from the same transparent silicone.

A similar design of the pumping knot caused doubt. Water, of course, sucks without problems, but the oil can quickly dig or soften and deform rubber membranes and valves, bringing a gadget to a dissent state. Therefore, after finding out the peculiarities of the design of the pump to the first plan of the experiment, not checking the possibility of swinging machine oil, which, in general, is obvious, but the ability of the device to keep performance after that!

Swing oil!

To pump oil through the hole of the probe, you will have to pick up a suitable plastic tube. This task is not to say that complex, but to some extent creative. The tube must pass into a narrow hole and have quite thin walls at the same time, so as not to resist the oil stream. In our case, a television antenna cable of Russian production was caught on hand, from the shell of which we pulled the central core and the inner braid by holding the tail in the vice.

The real experiment confirmed the effectiveness of the pump - about three and a half liters of oil from the WV Polo engine cheerfully pumped out somewhere in five or six minutes; The motor during this time heats up, but noncritical. The control paolding of the crankcase pallet stop showed that no more than half a cup of oil is low. In general, a non-critical amount that can also be reduced, placing in the oil-tapping neck, after bubbles, grams of 200 pure fresh oils went from the pump.

Did the pump durable?

Leave the pump after replacing the oil in the crude condition fraught. Lubrication is capable of freeing or dissolving the rubber stuffing of the rocking unit until you roll back your 10,000 km, waiting for another replacement ... Therefore, we conducted a control measurement of the pump on the water (which showed that the pump pumped three liters of water in about two minutes), after which Thoroughly washed it and the productivity was measured again in a month to make sure that it did not deteriorate and the effectiveness did not decrease.

Your conditions

Oil in the engine loses its properties over time, so it is necessary every 10,000-15,000 km of mileage. Make it the easiest all in the car service, but you can save, after performing your work yourself. Happy garage owners with observation pit to merge oil, you just need to unscrew the drain plug in the engine crankcase pallet. The one who does not have access to such a pit can use a pump for pumping oil through a hole for the probe.

Immediately notice: this device will only help you out if the oil filter is needed when the new oil is needed when filling the new oil, you can reach the top. If you can replace the filter in your car only below, the pump for pumping oil will not greatly simplify you work. After all, it will still have to be subject to the car.

Before work

Already at the stage of preparation for the test, we revealed several features of the electric pump. First, our copy was initially unchanged. We disassembled the pump, and it turned out that the electric motor does not rotate, since the mechanical part of the gearbox is screwed to it too much. The cause of the malfunction was eliminated - and the device earned.

Secondly, the electric pump does not work on dry, so you need to remove the plugs on the holes under the tube and pour into the device with a syringe 40-50 ml of oil.

Thirdly, the tube included in the hole of the oil probe has a diameter of 6 mm, while the diameter of the tube for the probe on some machines can be smaller diameter. Simply put, not to each engine will be able to connect the electric pump. Among them, for example, a 1.8-liter motor on which we initially wanted to spend all the work.

Paradoxically, thanks to this, our experiment was only "cleaner": we decided to drain the oil with an electric pump on the same car on which some time ago. This is Chevrolet Aveo.

Pure experiment

Inserting into the hole for the probe tube, connect it to the pump. On the other hand, fasten the second tube - to drain the oil. Its the second end is lowered in a 5-liter plastic bottle of drinking water (transparent packaging allows you to control the volume of the fusion of the working fluid). We are convinced that the pump is turned off, after that connect the terminals of the device to the car battery, observing the polarity.

Turn on the pump and start pumping. The oil rises along the tube inserted into the hole of the probe, passes through the device and follows from the second tube into the plastic container.

After a few minutes, the sound published by the oil pump engine has changed, since the engine has become easier to work. This means that the oil is over. I will be convinced of this, pesting the tube inserted into the hole of the probe. If the sound of the pump does not change, turn off the device.

Check

To understand how efficiently the electric pump coped with its task, raise the car on the lift and unscrew the drain plug in the pallet. Oil flows rather intensively. During our past experiment, when we used a vacuum installation for similar work, this was not.

The conclusion is obvious: it is not worth it with the help of an electric pump. And although the device is of interest, it clearly needs to be improved.

That in the rest

Until the end of the drain oil from the engine, we replaced the oil filter and poured fresh oil. The result of the experiment did not satisfy us.

Despite the fact that the experiment with the Electronasus questioned the effectiveness of this device, replace the engine oil in the garage without observation pit. If you use a vacuum installation for this. It is twice as expensive than the electric pump (2600 rubles against 1300-1350), but has two significant advantages compared to it: a vacuum installation, pumping the oil is almost completely, more efficient and universal, as it allows you to drain it from the engine even through a narrow hole for oil probe.

The standard procedure for replacing the oil in the car engine requires the presence of observation pit, overpass or lift. In the car service, such a service costs about 1000-1500, while it is not always possible to see the process with its own eyes, and therefore there is a risk that the engine will not fall into the engine. To save money and nerves and do not look for a special area to replace the oil with the usual way, it can be changed independently through the probe tube, for this it uses a compact action to the type of action similar to the usual pump.

1 Replacing the oil through the probe - how does it work?

To replace the lubricant fluid directly through the oil probe tube, a special device is used. It is a vacuum pump with special tubes and transition elements. There are many models in the market that differ in speed, tank capacity, design and durability. Such a gadget is manual and electric, can have additional tubes and "chips", at the expense of which work on pumping happens faster. Regardless of the type, sizes and cost, almost all of them consist of the following details:

• hose or tube for pumping oil;
• the main tank for liquid;
• special pump for pumping and injection air.

The tank has two holes, in one of which is inserted the main tube, and in another entrance from the vacuum pump. After that, the procedure for pumping a waste fluid is carried out. To do this, get the oil dipstick and paste the end of the hose in his tube, so that it reached the Carter bottom. After that, an electric or manual pump is used, with which air is injected and the pressure difference is created.

Next, the pump is removed, the check valve records the necessary pressure, due to which the oil gradually begins to flow from the pallet into the tank. Electrical pumps have special stoppers that are configured to stop the device to achieve the required amount of lubricant.

If there are no such systems, the tank has a translucent kind so that the owner of the car saw how much fluid is obtained. The process itself takes from 15 minutes to half an hour, it all depends on the type of oil used, its properties for viscosity, the degree of contamination and the power of the installation itself.

Before conducting such a procedure, you must fix the car on the maximum flat plane and make the engine to work for a few minutes. This will allow oil inside to warm up to operating temperatures, the sediment will rise from the bottom, and during the pumping process, its maximum amount will flow into the tank along with the main liquid.

2 pros and cons replacement of oil pump

Among the main advantages of oil replacement through the tube of the probe in the engine, you can select the lack of need to drive the machine to the viewing hole or the lift, once again unscrew the drain plugs from the pallet, remove the crankcase protection, which is on many models of the car, select suitable containers, etc.

This method is relevant for those models of cars, in which the oil filter is located in the open space, so it can be reached and unscrewed.

This is especially important for many cars models, including popular Lada Grant, Ford Focus, Volga 3110, almost all "Skod" with MPI gasoline engines, some of the CFNA Volkswage Motors, on which the filter is located directly near the cylinder head. If it is downstairs, near the crankcase, then drive the car onto the platform or the lifting device will have to be in any case, and without replacing the filter, the whole process loses its meaning.

With all the advantages and convenience of such a way, he also has consists of people who often argue in the environment of motorists and specialists. The fact is that when using low-quality oil, as well as in the case of its serious contamination, due to a long ride or viscosity inconsistencies and type, the production of additives and other deposits are settled on the bottom of the pallet, which are formed as a result of intensive engine operation.

After pumping with a vacuum, heavy composite sediments remain at the very bottom, and after a new oil is poured into the engine, these deposits are mixed with a new composition, significantly reducing its resource and lubricant efficiency. Therefore, experts recommend to alternate both methods, making a replacement both through probe and the classic path of the oil from the pallet with the engine flushing procedure.

Remember that when using a high-quality and suitable oil, the correct replacement of it every 8-10 thousand mileage kilometers, there will be no precipitate on the bottom, of course, if certain elements are properly in the motor system, especially the details of the cylindane group group are not worn.

To the advantages of the method of pumping oil with their own hands by creating a pressure difference also accessibility, mobility and compact device. The replacement pump is inexpensive, it is used as a reusable device, placed in the trunk and can work in various climatic conditions. But to ensure durable work, it is necessary to periodically clean from oil pollution, which is not always quick and not quite convenient.

3 How to choose a high-quality device?

There is a huge number of models of domestic, European and Chinese production in the market, the value of which varies from 500 to 12,000 rubles. There are more professional options that are found on various car services, as well as manual, electrical, rotary, etc.

When choosing an electrical device of the factory type, experts recommend paying attention to parameters such as:

• Power and performance. The optimal option for pumping the average oil volume (4-5 liters) for 10-15 minutes - 50-150 watts.
• Material and build quality. The main criterion is a tightness: the higher, the more efficient the operation of the device. High-quality pumps and details are made of stainless steel.
• Manufacturer and cost. Do not buy semi-professional models, they have high performance and speed, but cost expensive and more suitable for installation in car services. The optimal price with the stated parameters of a more or less high-quality pump is 1500-2500 rubles.

It is worth noting that both manual and automatic type of pump can be made with your own hands. The easiest and most proven way is to use a conventional electric pump (you can take a compressor for swinging wheels) or use a more compact version of the device, for example, a small electric pump for decorative fountains and aquariums. It is easily placed in the palm, it has the necessary performance and works from the on-board network.

4 How to make a pump with your own hands - use a proven way

The cost of such a mini-pump does not exceed 500-700 rubles when ordering through the Internet or will be slightly expensive when buying in a specialized store. Standard device for pumping with tubes and wires will cost about 2000-2500 rubles. As a result, saving is small, but, as you know, much more pleasant what is done with your own hands.

Before you buy or independently make a device for pumping oil through the dipstick, it is worth sure to make sure that the engine and layout of other parts in the operating space allows you to unscrew or remove the oil filter without the need to climb.

The principle of operation of such a "water" pump is similar to more expensive analogues of the Karker type, which is based on the operation of the use of high pressure. But, given the cost of this compact device, instead of metal pistons, silicone membranes with an eccentric on the engine are installed in it. The latter during operation rotates, lifting these most membranes in one or another. Nearby are the check valves made of silicone material.

In addition to the device itself, two more tubes for pumping oil, suitable plastic or glass container (by 5-7 liters) and two wires with "crocodiles", with which the pump will be powered by the battery. Wiring can be used from any old electrical appliances, for example from a multimeter, etc. They need to be connected to the appropriate conclusions on the pump, carefully insulate the connection points and consistently connect to the battery before starting work, not forgetting to observe the polarity.

With a tube for pumping the oil a little more complicated, as it should be thin to freely pass into a narrow hole from the probe, and at the same time have thin walls so as not to create excess resistance during the pumping of warm oil. Universal and verified option to use tubes from a wiper system of some old car. You can use an unnecessary television cable from which all the veins and inner winding are pulled out, or other types of material, there are no limits for the creative approach to the question.

One part of the tube is lowered into the prepared container, the other is neatly soaked into the hole in the engine. The wires are powered by the battery, check the tightness of the tubes and wiring at the input and outlet of the pump and start the device. With properly selected materials, with the help of this method, 4-4.5 liters of oil can be downloaded for 10-15 minutes, not even staining hands.

Assembly and materials may vary, but the principle of action is the same. And to use this device many times, be sure to clean the pump after each pumping. To do this, the inlet and output tubes need to be omitted into a small container with gasoline and turn on the pump so that it has worked for several minutes, then instead of gasoline, use water with the addition of any effective detergent.

A vacuum pump for pumping oil from a car engine is a very useful device that allows you to quickly get rid of the old lubricant. The unit has a simple design, thanks to which everyone can make a homemade pump.

Principle of operation and pump device

Pump for pumping oil electric has a fairly simple design and small dimensions. Most of the majority of models is not more than 500. The regular equipment of pumps consists of two clamps for mounting and two hoses for pumping out engine oil.

Internal pumping chambers of pumps are lubricated with oil, which does not allow items to wear when you first start. At the same time, the chambers are completely sealed and have rubber seals. Rotary plate plates are made of stainless steel, aluminum and copper.

The brake pump is equipped with a reliable engine, which drives the gearbox with blades. On average, the voltage of the motor is from 3 to 12 volts. At 12 volts and the strength of the current 8 A, the rotation speed of the shaft is approximately 14100 rpm. Gearboxes in most pump models do not have lubricants, so lubricant has to be submitted to the item alone.

The pump for pumping brakes works as a result of fluctuations in working volumes between the plates located nearby and the pump housing sites with the rotor surfaces. During this camera in the left part of the unit increases due to the rotation of the eccentric rotor clockwise. It lowers the pressure inside the pump, so that liquid falls into it. The working volume in the right part of the device decreases, which contributes to the injection of fluid.

How to choose a pump for pumping oil?

Self choose the device for pumping the oil is simple enough. This requires learning a number of important characteristics to which:

• Power Power - for rapid oil pumping, a unit will be required, with a capacity of 50 to 150 watts;
• Performance - a good option will be the device that pumps at least 500 ml of oil per minute;
• The material from which the pump was made is best to buy an aggregate with stainless steel;
• Manufacturer country - experts do not advise buy Chinese and Korean pumps, as they do not serve for a long time. In addition, they are constantly heated;
• Assembly quality - the pump must be completely sealed without any gaps.

Having studied all these characteristics, the buyer will be much easier to choose the appropriate device, and do not overpay for it.

Despite all the benefits of the pump for the brake system, not all owners of the car want to spend on it. In this case, you can make a pump to replace the oil through the probe with your own hands. For the manufacture of the simplest device, one large syringe will be required to which the probe will be mounted. The only minus of such a mechanical device is that the driver is forced to independently pump oil.

Another option is the manufacture of a pump with a motor. Such a device does not require a constant presence of a person.

To make a homemade pump for pumping oil:

• Electric motor;
• Ball pen;
• Waterproof superchalter;
• Cap from deodorant;
• Small gear;
• 4 pieces of plastics. Diameter of about 1 cm.

The procedure for making a vacuum pump for pumping oil from the engine through the diploma is as follows:

1. First you need to break all the gears teeth and fit it under the size of the cap;
2. After that, you need to glue pieces of plastic so that they are located opposite each other at an angle of 90 0;
3. In order to form the body of the device, the cap walls must be cut off, leaving them with a height of 15 mm;
4. From above, the cap must be drilled a hole to fix the axis of the motor in it. The second hole must be drilled from behind to put the handle housing in it;
5. After that, it is necessary to fully disassemble the ball handle, leaving only its housing. Next, the housing must be glued to the side opening of the cap;
6. Motor must be glued to the top opening of the cap;
7. Next, on the axis of the motor will need to wear the impeller;
8. After that, it is necessary to cut the plastic panel, the diameter of which should be the same as the diameter of the cap;
9. In the panel you need to drill a hole in which oil will fall. The panel itself is attached to the pump housing.

The manufactured pump does not have a high power, but it will be successfully cope with its main task. The productivity of the device is approximately 200 ml of oil per 1 minute of operation.

Change the oil is now very simple and completely to do something, without overpaying the dealer or service. This is especially true when there are no pit in the garage.

The article briefly wrote how to change the oil in Skoda through the probe on his own, with the help of such a miracle motor from China. What will take to work.

I already posted a video on this unit from the car owner.
Now, I purchased a pump myself - the other day I did, took off the video test. With comments.

All oil merged no more than 5 minutes.

I took a motor who has this seller the pump number 1400 \u003e\u003e \u003e\u003e

Who will order: the tube one breathing came. Not significantly, stuck superclaim.
Or you can buy in "Ob" saw.

The seller did not respond to this.
Opened the dispute - returned 430 rubles.
Free delivery by courier to any address.
I was brought directly to work.

The thing is good comfortable, and most importantly quickly and economically for those who do something alone.
For Motor 1.4 atmo not suitable, The tube is thick through the dipstick will not climb, you need to change thin on more.

Who is not aware: butter to swing on the hot. High speed drive, slightly. Maxidote I had 79 degrees. Motor drowned, gave a cool a few minutes 10-15.

It is not necessary to get involved in the pump: all the same, the normal drain has always been considered through a drain plug. Alternate every two oil replacements through the bottom.

At the expense of the resource:the thing is not for the service, but for home use. According to reviews, it serves more than more than a year.

Actually, here is the video itself - the pump for self-replacement of oil in the engine

To work, you will need:

1. Engine oil 5l;
2. Oil filter.
3. Chinese pump.
4. five-liter eggplant under workshop.
5. Nozzle for removing the oil filter.
6. Rod for wiping Gorlowin.
7. Gloves.
8. And 30 minutes of free time.

At first, the cold engine was measured on the cold engine.
At the probe, everything was vague and incomprehensible to what level, measured three times three.
Then drove the engine traveled a bit, a temperature of 79 degrees appeared on Maxidote.
Motor drowned, gave a cool a few minutes 10-15.

Then opened the hood, unscrew the oil-tapping cover, the rag wipe the neck with a lid from the mud, since the sand hits a lot. Unscrew the oil filter, there is also a watery place, too, dirty was.

Then he took off the dipstick, and put a thin tube from the pump to the end, the second tube is thickening into an empty eggmarket, connected the terminals to the battery and turned on the pump.
Oil ran down quickly, time to roll oil took 4-5 minutes. And the eggplant is complete.
Butter was hot but not boiling.
Tubes when pumping became soft and puffy.

Next, screw the new oil filter, and fill 5 liters of oil.
We twist the oil-tapping lid, put the dipstick in place.
We remove the entire pribroud in the trunk, and we start the motor.
Let me work 5-10 minutes, the wasting.
Speedometer at maxidote on zero.
Ready.
Everything is very simple quickly and economically.
Specify questions.

And this video auto owner sent me almost a year ago.
On the video, the shooting was made in winter - everything went about 25 minutes.
