【MEIRUIER FILTER】The classification of the fuel filter

2016-08-16 View:

There are three kinds of fuel filters, they are diesel filter, gasoline filter, natgas filter. The main function is to remove the harmful impurities of engine fuel system, which reduce the engine wearing and blockage.


The working principle of the fuel filterfilter

The fuel filter on the pipeline which is cascaded in the fuel pump and the throttle valve body. The filter is made up of Aluminum housing and Stainless Steel holder. There is high-efficiency filter paper, whose shape is chrysanthemum to increase the flow area. Electronic injectioncan not be in common use with thecarburation filter.

As the electronic injection filter usually bear the pressure of 200-300KPA, so the pressureproof strength requires to be above 500KPA,  carburation filter has no requirement.

 

The categories of fuel filter: Diesel filter, gasoline filter,natgas filter

1. Diesel filter

The structure of diesel filter is almost the same as oil filter, it includes replaceable filter and spin on filter. The working pressure andanit-oil temperature is lower compared to oil filter.

But the requirments of the filtration efficiency is much higher than oil filter. The element of the fuel filter is made from paper, some are made from hair felt orhigh polymer material 

2.  Gasoline filter

The gasoline filter includes carburation filter andelectronic injection filter. For the carburation engine,  thefilter is on one side of the entrance of the fuel delivery pump, which the working pressure is low and usually use nylon housing. Electronic injection filter is located on the side of the fuel delivery pump.

The working pressure is high and it usually uses metal housing. The element of the gasoline filter is usually made of paper and some use nylon and high molecular material. Thecombustion style of the gasoline filter is different from diesel filter, the whole requirement is not as strict as diesel fitler, so the price is cheaper.

 3. Natgas filter

 Natgas filter is widely used inmetallurgy, chemical engineering, petroleum, papermaking, medicine and other sectors. The gasoline filter,  it is an essential device in pipeline of transporting the media, it is usually installed in theentrance point ofthe reducing valve, decompression valve or other equippments, which is used to remove the impurities of the media to protect the valve and normal use of the equippments and reduce the cost of the maintance.

The function of the fuel filter

The function of fuel filter is to remove the ferric oxide, dust in the fuel and prevent the blockage of fuel system, also reduce the wearing of the machine, ensuring the steady operation of the engine and improve the reliabitity.
