Reasonable countermeasures to prevent damage to filter device in four-column hydraulic press

  The effectiveness of the filter plate in the four-column hydraulic machine depends on filtering out the residue mixed in the gear oil, reducing the environmental pollution of the hydraulic oil in the system software, and ensuring the basic work of the four-column hydraulic machine. The problem caused by the filter plate of the four-column hydraulic press is specifically manifested in the fact that the actual effect of the filter device is not very good, and the hydraulic oil cannot be guaranteed to be cleaned.
The reasons for the damage and deformation of the filter element are: the filter element is blocked and incorrectly selected. In order to clear the problems, inspections should be carried out on time to carry out maintenance and cleaning of the oil filter; the four-column hydraulic press effectively selects the filter plates that meet the requirements for compressive strength, strength, and current carrying capacity, and take various unique reasons Effective countermeasures.
For metal material porous filter plates, when the operating temperature is high, the temperature of part of the oil at the filter plate of the four-column hydraulic machine is high, which exceeds or reaches the melting point of the electric welding point, plus the original electric welding is unstable and the hydraulic oil is damaged. For example, the porous filter plate at the inlet of the high-pressure plunger pump is changed to silver welding material many times, and their melting point is improved.
Four-column hydraulic presses mostly use metal powder calcined filter plates. After falling particles enter the system software, they block the throttle valve hole and jam the valve core. The reason is that the quality of the calcined powder filter element is not good. Therefore, you must choose the calcined type that meets the test standards. Oil filter.
Generally, the surface of the filter element will gradually heal during the whole process of the filter plate. It is the basic problem to cause blockage. The blockage often mentioned here is the more serious blockage caused by the four-column hydraulic machine. After the filter plate is blocked, it will cause abnormalities in the oil pump. , The pump produces noise, and the system software cannot suck in sufficient hydraulic oil to cause the pressure to be unable to increase. There are many bubbles in the hydraulic oil and its filter element is blocked and the pressure increases, which causes the problem of destroying the four-column hydraulic machine.
