After the use of hydraulic oil (especially hydraulic oil in the hydraulic tank) most of US Internet users will search online how to filter hydraulic oil or hydraulic filter. In fact, this kind of equipment has already appeared earlier, called oil filter, so we can find the oil filter directly to find what you need later. Equipment.
Hydraulic oil filter oil filter is pumped into the equipment through the oil pump motor, and then through the filter core, the precision of the filter core is higher, 1 microns to 10 microns is more common, the filter core is also stainless steel cleaning filter core, remove the impurities in the oil, then through the three-dimensional body flash, into the flash tower, high temperature removal, high temperature removal Water, usually using 60 degrees Celsius temperature, in the case of not affecting the oil in the case of water removal, after the condenser bar water out, the whole process is fully automated, no manual guard.
1) damage to filter plate caused by filter plate failure is common.
If there is a large number of filter plates damaged, the following factors should be analyzed:
(1) the manufacturing quality of the filter plate;
The selection of material for filter plate and whether the head of feed pump is matched;
(3) in diaphragm press, the quality of diaphragm oil filter and the quality of internal steel lining should be considered simultaneously.
Under normal conditions, the pressure on both sides of the filter plate is in equilibrium. When both sides of the filter plate are in different stages of filtration, that is, one side is filtered and the other side is hydraulically extruded. A pressure difference is formed on both sides of the filter plate, thereby damaging the filter plate. The reasons are as follows:
(1) during the unloading process, the amount of mud remaining on both sides of the filter plate is quite different.
2. When the filter press begins to filter, the stopping time of the feed pump is longer in the middle, and the filter cake in the half flow state of the filter chamber sinks to varying degrees.
The feeding hole of the filter plate is blocked.
(2) there is a phenomenon of ejection between filter plates during the filtration operation of the automatic vacuum oil filter between the filter plates.
(1) the filter cloth is folded on the compression surface of the filter plate frame.
The filter cloth is damaged;
(3) the lateral beams of both sides show different degrees of lateral bending (horizontal direction).
(4) the thrust plate is not pressed or the hydraulic cylinder has less pressing force.
When the oil filter is working, the filter oil is needed to breathe in the strong magnetic filter under the action of the outside atmosphere and the vacuum suction. The large particle impurity is filtered out. The oil is heated to the multistage coalescing filter after heating. The water separation filter uses the technology of strengthening the hydrophobic and hydrophobicity to improve the interaction of the oil-water two phase interface. With the force, the fine water droplets in the oil are accelerated, and the large water droplets are separated and precipitated from the oil, and they are precipitated in the pure water storage device, and the impurities are removed into the three-dimensional vacuum flash tower. Through the spray device, the oil in the flash Bauer ring makes the oil produce a larger aeration area and a longer retention time. Sufficient oil and gas separation processes are carried out to remove residual trace water and gas in the oil.
The vaporized water vapor, light water vapor, light hydrocarbon and other gases pass through the strong wind condensing device, the water vapor and the condensable gas are condensed into the vacuum buffer room with the non condensable gas, and the cooling water is discharged through the drainage device, and the uncondensable gas is discharged through the vacuum pump. The oil liquid that goes out of water, gas and mechanical impurities is imported into the oil pump by the oil pump, which is the clean oil purified by the oil filter to complete the whole purification process.
