How to prevent the filter of the 200-ton four-column hydraulic press from being damaged?

The function of the filter plate in the 200-ton four-column hydraulic press is to filter out impurities mixed in the hydraulic oil, reduce oil pollution in the system, and ensure the routine work of the four-column hydraulic press. The problems caused by the filter plate of the four-column hydraulic press are mainly manifested in the poor effect of the filter system and the failure to ensure that the oil is clean.

The reasons for the damage and deformation of the filter element are: the filter element is blocked and the selection is wrong. In order to eliminate the above problems, the oil filter should be checked and maintained on a regular basis; the four-column hydraulic press should reasonably select a filter plate that meets the requirements in terms of compression resistance, strength, and current-carrying capacity, and take corresponding measures for various special reasons.

For the metal mesh structure filter plate, when the working temperature is high, the local oil temperature at the filter plate of the 200-ton four-column hydraulic press is high, exceeding or reaching the melting point of the welding point, and the original welding is not strong, the impact of the oil will be Leading to poor contact, such as the mesh structure filter plate at the inlet of the high-pressure plunger pump has been changed to silver solder many times, and their melting point has been optimized.

Four-column hydraulic presses mostly use metal powder sintered filter plates. After falling particles enter the system, they block the orifice and block the valve core. The reason is that the quality of the sintered powder filter element is not good, so you must choose a qualified sintered oil filter.

Generally, during the working process of the filter plate, the surface of the filter element will gradually heal, and the blockage caused by sodium is a common problem. The blockage mentioned here is a serious blockage of the four-column hydraulic press. After the filter plate is blocked, it will lead to abnormal pump oil and pump failure. Noisy noise, the system cannot absorb enough oil and the working pressure cannot go up, there are a lot of air bubbles in the oil, and the working pressure increases due to the blockage of the filter element, which leads to damage to the four-column hydraulic press.
