How to operate the air pressure oil filter?

The pneumatic oil filter is mainly composed of crude oil barrels, air compressors, slot cards and other components. Its working principle is that the air compressor presses the gas into the crude oil barrel through the slow air tank, and the crude oil flows out through the filter cloth. During filtration, the solid particles in the crude oil encounter the filter cloth, and the particles are blocked on the surface of the filter cloth to form filter residue. 

The pneumatic oil filter itself is also a kind of filter layer. The working capacity of the pneumatic oil filter increases with the increase of pressure but also decreases with the increase of the thickness of the filter residue. At this time, the machine must be stopped and the filter residue must be removed.

The operation method pneumatic oil filter:

1. Place the pneumatic oil filter in a horizontal position, otherwise it will seriously affect the use effect.

2. Place another accessory filter cloth flat on the installed filter cloth to remove the residue.

3. Check whether the pneumatic oil filter is operating correctly. The method is: to check whether there is gas discharged from the exhaust port of the air compressor, and if there is gas, the direction is correct, otherwise the direction is incorrect.

4. After checking, pour the crude oil into the crude oil barrel (stop feeding the crude oil when it is 1-1.5 cm lower than the air inlet of the crude oil barrel).

5. Close the barrel cover, make the barrel cover and the mouth of the oil barrel fully contact, then use 4 slot-shaped cards to tightly clamp the barrel cover and the barrel body together, and ｉｎｓｅｒｔ the positioning pin.

6. Close all the vent valves, open the air inlet valve on the filter barrel (the valve connected to the hose), and then start the air pressure oil filter to start filtering. When gas is discharged from the oil outlet, it means that the filtration is complete. At this time, the power should be turned off, and the barrel cover should be opened after the vent valve is opened to discharge the gas in the barrel.

7. When cleaning the residue, the filter cloth should be flattened and the filter residue should be scraped off with a wooden, bone or bamboo scraper. After using the filter cloth for some time, it should be cleaned. The cleaned filter cloth must be dried before use, otherwise it will seriously affect the filtration speed.

8. The filtration speed of the air pressure oil filter is closely related to the coarseness of the solid impurities in the crude oil. If the filter residue is too fine and the relative viscosity increases, it is easy to clog the micropores of the filter cloth, thereby reducing the oil filtering speed. Therefore, we recommend that users install a metal mesh with a slightly larger mesh (generally slightly larger than the mesh of ordinary household window screens) under the oil outlet of the air pressure oil filter when pressing the oil. Make the crude oil contain a certain proportion of coarse residue so that when filtering, these coarse residues will also form a filter layer, which can better improve production capacity and quality.

9. When the air pressure oil filter is working, the slow air tank will produce water accumulation, so it is necessary to regularly open the slow air tank drain valve to drain the accumulated water (recommended once a day).
