The function of diesel filter is to filter out harmful impurities and moisture in the fuel system, protect the normal operation of the engine, reduce wear and tear, avoid blockage and improve the life of the engine.
Oil-water separator is a kind of equipment, which is divided into catering oil-water separator and industrial oil-water separator. Catering oil-water separator is used for sewage treatment in catering industry; Due to the requirements of environmental protection, the sewage discharged from ship machinery in rivers, lakes and seas must be treated, and an industrial oil-water separator is needed.
The diesel engine fine filter is designed for the two-stage filtration commonly used in diesel engines at present. Together with diesel oil-water separator, it forms two-stage filtration. The oil-water separator is used to filter the water in diesel oil, and the fine filtration of diesel oil is the fine particles in diesel oil.
Second, the structure is different.
1. The structure of diesel filter is basically the same as that of oil filter, including replaceable and rotary type.
2. As the main filtration in two-stage filtration, diesel fine filtration is also the last line of defense for impurity filtration, which requires high filtration efficiency and service life. At present, according to the national standard of diesel heavy truck, the filtration efficiency of 3-5 micron particles, 5- 10 micron particles and 10 micron particles is required to be as high as 98.6%, 99.8% and 99.9% respectively.
While ensuring high filtration efficiency, it is also necessary to meet small flow resistance to ensure reliable operation and abundant power of the engine.
3. The compressed air oil-water separator is used to separate condensed impurities such as water and oil in the compressed air, so that the compressed air can be preliminarily purified. The general working pressure is 0. 1Mpa- 2.5Mpa.
Another oil-water separation system, which uses stainless steel wire mesh to coalesce filler inside and steel welded tank structure outside, generally uses a pressure of 0. 1Mpa-2.5Mpa. Its principle is to use the organic combination of cyclone and stainless steel wire mesh to catch fog, and at the same time, it can effectively remove dust, water and oil mist in compressed air by adopting mechanisms such as direct interception, inertial collision, Brownian diffusion and condensation, with large water and oil removal capacity and wide working range.
Third, the function and working principle are different.
1, the function of diesel filter is to filter out harmful impurities and moisture in the fuel system, protect the normal operation of the engine, reduce wear and tear, avoid blockage and improve the life of the engine.
2. Working principle and workflow of oil-water separator system: 1 Water enters-> from AOD pump (gas diaphragm); 2 Flow control valve enters-> The first-stage honeycomb chamber washed with water has many dense honeycomb compartments, and the tiny particles in the water settle in the honeycomb chamber in the current.
Wastewater flows upstream->; 4 mesh water distribution holes (5/32 inches) enter->; 5 adsorption chamber and extraction chamber. Water flows into the oil absorption chamber composed of JT57 liquid filter media. In this process, oil and grease are absorbed in large quantities, and a large number of complex heavy metals, organic matter, total suspended solids, BTEX, PCBs and many pollutants in water are extracted.
Then the water flow turns upward in the adsorption chamber and enters->; 6. In the secondary honeycomb chamber, water flows up and down three times through the secondary dense honeycomb interlayer, and the residual trace oil will float up and gather in the upper part, and the water will enter->; 7 clean room, and finally water is discharged from the bottom of the clean room.
The residual trace oil distributed in the secondary honeycomb chamber and the clean water chamber is skimmed into the external oil storage container through the oil skimmer arranged at the top of it and removed.
3. In order to make the engine drink clean and high-quality diesel oil during use and avoid abnormal wear and tear of rail parts, only fine filtering of diesel oil can effectively protect the high-pressure pump, electronically controlled injector and rail nozzle, and reduce unnecessary high maintenance costs. Diesel fine filter is generally installed on the engine.
Extended data:
First, the characteristics of catering oil-water separator
design feature
The grease trap is a box structure, which can be buried underground or on the ground. After the anti-skid box cover is opened, sewage flows into the residue collection chamber through the inlet, leaving solid substances. Sewage flows into the grease trap chamber through the lower edge of the partition, and a large amount of grease floats on the surface after gravity separation. Degreased water flows into the grease trap through the lower edge of the partition, and the grease floats on the surface again. After degreasing, the sewage outlet flows into the unified and standardized clean water sampling room specified by the State Environmental Protection Bureau, which is convenient for sampling and discharged through the discharge pipe.
The whole oil separation tank has fine and reasonable design, small volume and high efficiency, and the raw materials are stainless steel and FRP.
Product characteristics
1, low price, no consumable parts, one-time investment and perennial benefit.
2. There is no need for power and electricity, and there is no need for operating costs. After the sewage flows in, it is completely self-purification and convenient for management.
3, the material is hard, easy to clean, and has a long life.
4. Prevent the sewer from being blocked, avoid the breeding of rats and insects, the odor overflows, and the rotten oil causes unnecessary cleaning, thus prolonging the service life of the sewer.
