The working principle of 200 plate and frame pressurized oil purifier filter oil

　　200 plate and frame pressurized oil purifier filter oil is suitable for LY plate and frame oil filter 30L/MIN, BASY plate and frame pressurized oil filter 50L/MIN, plate and frame oil filter 100L/MIN, plate and frame type Reference for the use of plate turbine oil filtration and purification equipment such as oil filter 150L/MIN, plate and frame pressure oil filter 200L/MIN. The working principle of turbine oil filtration is easy to understand, and the equipment operation is easy to learn.

　　200 plate and frame pressurized oil purifier filter oil adjustment and operation:

　　Before use, check the installation position of the filter plate and filter frame of the filter part. Starting from the thrust plate, the piece is the plate, the second piece is the frame, the third piece is the plate, the fourth piece is the frame... and so on. Arrangement, the number of plates is one more than the frame. The plates and frames cannot be reversed. If they are installed reversely, they will not function as a filter. The grease coated on the plates, frames, thrust plates and compression plates must be removed. Before the test run, filter paper should be clamped between the plates and frames to press the plates and frames tightly.

　　Before starting the machine, the oil pump shaft must be rotated two or three times by hand. It is considered that the rotation is flexible and there is no card group phenomenon. Then connect the oil-resistant hose (or iron pipe) with the oil suction end and the oil discharge end of the oil filter, and then check the in and out Whether the oil pipe is blocked or leaking oil or gas, open the oil inlet and outlet valves, close the oil return valve and the pressure reducing valve (connected to the oil inlet and outlet ends of the oil pump), and then start the machine.

　　The correct rotation direction of the motor is the direction indicated by the arrow on the oil pump cover and gear pump nameplate, and it cannot be reversed.

　　If everything is normal, the oil pump will suck oil within a few seconds after starting up. If it still does not suck up oil within half a minute, it means that the suction end of the oil pump and the oil sample valve are leaking. You should stop working immediately and try again after troubleshooting to prevent gears. The pump is damaged when there is no oil.

　　If the value indicated by the pressure gauge is found to be as high as 0.4-0.6Mpa after the start-up, and the oil pump makes an abnormal noise, it should be shut down immediately to find out the fault and eliminate it.

　　200 plate and frame pressurized oil purifier filter oil is a kind of mechanical equipment that filters solid impurities and moisture in the oil and improves the oil performance. The plate and frame oil filter is composed of filter bed, oil pump and coarse filter. The filter plate and the filter frame are lined with filter paper or filter cloth as the filter medium. The filter plate and the filter frame are fixed to form a separate filter chamber by the pressure of the pressing device, and the filter paper is compressed between the filter plate and the filter frame Or filter cloth plays a filtering role.

　　The plate and frame oil filter is specially designed for various power plants, power stations, industrial and mining enterprises, lubricating oil warehouses, tractor stations, petroleum, chemical, metallurgical, defense units, etc., mainly used to filter transformer oil, turbine oil, engine oil, diesel For the moisture and impurities in the oil, stainless steel materials can also be used to filter the vegetable oil.

　　200 plate and frame pressurized oil purifier filter oil working principle The filter bed is a continuous operation, under pressure, the dirty oil is pressed into the filter group that is filtered to the side. It is composed of a set of filter plates and The filter frame is composed of a manual screw pressing device and a pressing plate. There are "ears" on the side of the filter plate and the filter frame to support the pallet of the frame. The filter plate and the filter frame are lined with filter paper or filter cloth as the filter medium. With the pressure of the pressing device, the filter plate and The filter frame is pressed between the fixed thrust plate and the pressing plate of the movable plate, thereby forming a separate filter chamber. The filter paper or filter cloth pressed between the filter plate and the filter frame plays a filtering role. There are two liquid holes at the corresponding positions of the filter plate and the filter frame. When compressed, they form two complete channels. The triangular side of the ears introduces dirty oil. After being filtered by the filter chamber, the other corresponding channels Bring out clean oil.

　　The working principle of 200 plate and frame pressurized oil purifier filter oil. Dirty oil is distributed to each filter frame through the input channel during filtration, and then enters the liquid hole of the filter plate after passing through the filter paper. The clean oil is collected in the output channel and discharged outside the machine . The dirt remains on the surface of the filter paper, and a small amount of water in the dirty oil is absorbed by the capillary in the filter paper. When the filter residue on the surface of the filter paper gradually thickens and the water content in the filter paper increases, the filtration resistance increases. Stop filtering, replace or clean the filter paper, and then continue to use.

　　The gear pump and the motor are connected with elastic rubber pads. In order to avoid mechanical accidents caused by excessive pressure, a safety valve is installed under the oil pump. The safety valve can be set to a lower value according to user needs, but it is generally not allowed to adjust to exceed the specified maximum pressure value.

　　The gear pump and the motor are installed under the filter bed, and the liquid output by the oil pump is delivered to the filter part through the discharge pipe and thrust plate.

　　The gears of the gear pump are supported by rolling bearings, which are lubricated by the oil delivered by the oil pump itself.

　　The coarse filter is installed on the suction side of the oil pump. Its function is to prevent large particles from entering the oil pump and destroying the oil pump. When the bolts on the coarse filter cover are unscrewed and the coarse filter cover is removed, the filter screen can be directly taken out for cleaning. When the coarse filter is full of dirt, not only will the oil filtering capacity drop rapidly, but the filter screen may also be damaged. Therefore, you should always pay attention to cleaning the coarse filter screen.
