Filter separator for diesel fuel: construction
In diesel fuel, which is sold at gas 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 life.
How is the filter-separator arranged?
This element is a combined system. 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 filter-settlers or the mechanisms of rough cleaning. 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 it is possible to remove from diesel up to 99% of water and up to 95% of 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.
Further, intermediate coalescing processes take place due to changes in flow directions. 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 with a cartridge-filter element. The DT is then fed to the pump.
A heating element can also be used in the device. 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 well, in conditions comfortable for them. On cars with such a system, drivers did not observe any problems with starting up during cold weather.
Filter elements: device and features
Next, consider what the design of the filter is. Separators for cleaning 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 the 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 due to the clog, the hydro-resistance of the system increases. The motor will start to run unstable.
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 for the filter separator for diesel fuel to perform its functions optimally, several key factors must be considered. 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.
Filter-separators in Russia: models, prices
Over the past 10 years, the range of parts for cleaning heavy fuel grades has significantly expanded in Russian stores. 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 automobile industry began 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.
"Separ-2000" with heating
These are the products of the German manufacturer Willibrord Lösing. These filters have long been known and are used by professional drivers. "Separ-2000" is a fundamentally new system of centrifugal cleaning. 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.
Features of "Separ-2000"
The algorithm of action is based on the principle of the centrifuge, 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 imported cars 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.
Stanadyne
This company is from the USA. It produces various products for cars.
Features
The Stanadyne diesel fuel separator is available in two versions. So, there is a version designed for working with engines, the capacity of which is up to 300 l / h, and a model for motors operating at huge loads with high throughput.
The main component is the head, which is then completed with various modules. So, there are three types of filter elements. This is 150 μm, 30 μm, as well as a fine filter for 2 or 5 μm. There are also heaters - side and top. There is a sump, a water level sensor, the possibility of manual or electric pumping. Reviews say that the device does an excellent job of its function. The cost of this filter-separator is about 2-3 thousand rubles. The device can be used on all diesel engines with a power of up to 350 horsepower in both cars and trucks.
Conclusion
So, we found out what the filter-separator is. примесей. As you can see, this is a very useful device that cleans DS from dirt, water and harmful impurities. Using the filter-separator, you extend the life of the fuel system.
