Working principle of BASY plate and frame pressurized oil purifier installation steps

　　BASY plate and frame pressurized oil purifier installation steps The working principle of the installation steps is 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 transformers The water and impurities in oil, turbine oil, engine oil, diesel oil, aviation hydraulic oil, etc., can also use stainless steel to filter vegetable oil. The machine 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. It has the advantages of simple structure, easy operation and low running cost.

　　Detailed device operation process of oil machine

　　(1) Oil suction strainer at the pump inlet

　　Introduction to the installation steps of the oil filter is used to maintain the pump so that it will not suck in large mechanical impurities. According to the requirements of the pump, coarse or ordinary precision oil filter can be used. In order not to affect the oil suction function of the pump, avoid cavitation. Phenomenon, the filtering capacity of the oil filter should be more than twice the pump flow, and the pressure loss should not exceed 0.01~0.035MPa.

　　(2) High pressure oil filter on pump outlet oil line

　　This kind of device is mainly used to filter out polluting impurities entering the hydraulic system. Generally, an oil filter with a filtration accuracy of 10-15 mm is selected. It should be able to withstand the working pressure and impact pressure on the oil circuit, and its pressure drop should be less than 0.35MPa, and it should have a safety valve or blockage signal device to prevent pump overload and filter element damage.

　　(3) The low pressure oil filter on the oil return line of the system

　　can filter out the pollutants that the oil has flowed into the oil tank, and supply clean oil to the hydraulic pump. Due to the low pressure in the oil return line, a refined oil filter with low filter element strength can be selected, and the oil filter has a larger pressure drop.

　　(4) Bypass filtration system where the device is outside the system

　　Large hydraulic system can be specially equipped with an oil filtering sub-system composed of a hydraulic pump and oil filter to filter out impurities in the oil to maintain the main system. Pay attention when installing the oil filter. Generally, the oil filter can only be used in one direction, that is, the inlet and outlet cannot be exchanged.

　　(1) The filter plate is damaged

　　Damage to the filter plate of the chamber filter press is a common problem. If the number of damaged filter plates is large, the following elements should be analyzed:

　　1 The production quality of the filter plate;

　　In the 　　 2 barrier pressing method, the volume of the barrier plate and the processing quality of the internal steel lining should be considered together.

　　3 Whether the selection of the filter plate material matches the head of the feed pump;

　　Under normal conditions, the pressure on both sides of the filter plate is in equilibrium. When the two sides of the filter plate are in different filtration stages, that is, one side is filtering and the other side is hydraulic kneading, a pressure difference is formed on both sides of the filter plate, and then the filter plate is damaged. The reason:

　　1 After the filter press starts to filter, the feed pump will park for a long time halfway, and the filter cake in the semi-active state of the filter chamber will sink to different degrees;

　　2 During the unloading process, the amount of mud remaining on both sides of the filter plate differs greatly;

　　3 The feed hole of the filter plate is blocked.

　　(2) Spray between filter plates

　　During the filtering operation of the active vacuum Chongqing oil filter, spraying occurs between the filter plates. The reasons are:

　　The thrust plate is not pressed tightly or the pressing force of the hydraulic cylinder is too small.

　　The filter cloth is damaged;

　　On the pressing surface of the filter plate frame, the filter cloth is folded;

　　The beams on both sides show different degrees of lateral twists (horizontal direction); Chongqing oil filter manufacturer

　　The solution is to carefully sort out the remaining filter cake (especially the lower part) on the pressing surface of the filter plate when unloading, perhaps flush the filter plate in time to ensure that the pressing surface of the filter plate is clean; tie the filter cloth well to ensure it is flat Sex.
