Filter separator for diesel fuel: construction

In diesel fuel, which is sold forgas stations of our country, contains a lot of heavy and harmful impurities for the engine. Also in the DT there must be paraffin particles and water. If the car will drive for a long time on such fuel, it will lead to serious deterioration of the engine. Each owner of the diesel engine encountered difficulties when starting the engine, a drop in power in the winter. The water contained in the DT, in the winter will turn into crystals. The fuel will be less liquid. These changes negatively affect the quality of the power unit and reduce its resource.

To protect the engine from substandardfuel, it is worth applying a filter-separator for diesel fuel (photo is in our article). In the Russian conditions, they are simply necessary. Fine and coarse filters are not enough. In addition, they quite often fail, and their price is high enough.

How is the filter-separator arranged?

This element is a combinedsystem. So, one part serves as a settler. Here, the solid impurities gradually accumulate at the bottom. In the second part, the filter separator for diesel oil retains water, paraffins and other substances dissolved in the DT. In addition, the housing can have a heating system, as well as elements for mechanical cleaning of diesel fuel.

Functions and operating principle

How does this element work? Most motorists often confuse equipment for mechanical separation with sediment filters or coarse cleaning mechanisms. Filter separator for diesel fuel performs mechanical cleaning. It allows you to remove various foreign particles from the fuel and protects the fuel system from accumulating dirt.

Among the main tasks that these products perform, two can be distinguished:

  • The process of impurity foreign substances.
  • Allocation of water.

With the help of these filters can be removed from the diesel engineup to 99% water and up to 95% mechanical particles. And this despite the fact that the fuel is very high concentration of both impurities. If a separator filter is used for diesel fuel with heating, it prevents the crystallization of water, as well as the paraffinization of diesel fuel at low air temperatures.

Fuel passes by a certain scheme. Thus, in the first stage, the emulsion is treated by centrifugal cleaning. For this purpose, the device is equipped with a stationary centrifuge. At this stage, the settler receives solid impurities and water.

Then there are intermediate processescoalescing by changing the flow direction. What is the essence of this stage of cleaning? Even smaller particles of impurities are separated from the fuel. In the final phase, the fuel is cleaned of microscopic particles by a cartridge-filter element. Then the DT is fed to the pump.

Also in the device can be appliedheating element. It contributes to a successful launch in winter. So, paraffins will not crystallize, but simply dissolve. Due to this, the components of the fuel system of the diesel engine will work long and regularly, in conditions comfortable for them. On cars with such a system, drivers did not observe problems with starting in cold weather.

Filter elements: device and features

Next, consider what isfilter design. Separators clean diesel fuel are equipped with a cartridge. This element is an ordinary plate, but small holes are made in it. The smaller their size, the more effective will be the cleaning of fuel. However, when choosing it is not worth chasing the numbers. The filter element, whose smallest hole diameter is only 2 μm, clogs very quickly. And as a result of the clog, the hydro-resistance of the system increases. The motor will start to run unstable.

filter design separators cleaning diesel fuel
Filters with large openings (from 30 microns andmore) are designed for cars that are equipped with old motors. Such a filter-separator for fine cleaning of diesel fuel can be used to work with a very dirty DT. The device of this type will last longer and will not cause the owner any problems with fuel supply. Naturally, after a while it will have to be replaced.

Experts recommend choosing such a filter,which will have the smallest hole size, but it is important to consider the type of engine and the conditions of its operation. For example, modern fuel systems such as Common Rail are very demanding on the quality of fuel. Therefore, with such motors it is not necessary to save on filters.

How to choose a cleaner for a diesel engine?

In order to filter the separator for dieselfuel could optimally perform its functions, it is necessary to take into account several main factors. So, experts recommend paying attention to the average fuel consumption, power supply voltage and heater power. Also, a water sensor and a heating monitoring system can be installed in the device. In addition, the construction has an additional pump for pumping the DT. And, at last, at a choice refinement of clearing and overall dimensions are important.

Naturally, a large number of additionaloptions make the filter-separator for diesel fuel more expensive. However, due to these same options, the process of servicing the product is facilitated. In stores, sellers often try to sell an expensive device and are motivated by the fact that the model is characterized by high quality work. In this case, the seller does not even try to find out about the fuel consumption of a particular car. But when the fuel consumption is small, and the working cross section is large, then the necessary centrifugal effect will not be created. As a result, an expensive device will turn into an ordinary settler.

Filters-separators in Russia: models, prices

Over the past 10 years in Russian storesthe assortment of parts for cleaning heavy grades of fuel has significantly expanded. The modern market offers a lot of products from well-known manufacturers. To choose is from what.

It is necessary to replace that even the domestic automotive industrybegan to introduce devices for separator cleaning of fuel. For example, now the filter separator for diesel KAMAZ is installed directly at the plant. This is the "Separ-2000" model and Mann-Filter products.

Let's consider some models quite popular among motorists who for a long time could prove the high efficiency on different cars.

"Separ-2000" with heating

These are the products of the German manufacturer WillibrordLösing. These filters have long been known and are used by professional drivers. "Separ-2000" is a principally new centrifugal cleaning system. Processing is carried out in several stages. The filter is suitable for operation on a wide variety of automotive equipment. Most automakers already install this equipment as standard filters.

This separator is a guarantee thatthe fuel will be cleaned as much as possible of dirt, water and paraffin. The cleaning process is carried out in three stages. If you install this device, the service life of the equipment in the diesel fuel system will increase 4-5 times. At the same time, the cost of equipment repair and maintenance is reduced.

Features of "Separ-2000"

The algorithm of action is based on the principle of workcentrifuge, although there is no filter in the device. All particles are heavier than DT, they are released from the liquid at different stages of the purification process and accumulate in the settler. The filter has elements with a cell size of 2, 10 and 30 microns. One of the significant advantages of this element is the self-cleaning function. The element is well cleaned of water and dirt.

Many car owners of domestic and importedthey choose the filter-separator for diesel fuel with heating "Separ-2000". Reviews about them are more than positive. The quality of cleaning is really good, as motorists say. The heating function is very helpful in winter.
