The function of the filter of the four-column hydraulic machine is to filter out the impurities mixed in the hydraulic oil, reduce the pollution of the oil in the system, and ensure the normal operation of the four-column hydraulic machine. The problems caused by the filter of the four-column hydraulic machine are mainly manifested in the poor filtering effect and the failure to ensure that the oil is clean.
1. How does the manufacturer of the four-column Hydraulic Press avoid the damage and deformation of the filter element?
The reasons for the damage and deformation of the filter element are: the filter element is blocked and the selection is wrong. Remedy: Check and clean the oil filter regularly in time; the four-column hydraulic press correctly selects the filter that can meet the requirements with pressure resistance, strength, and flow, and adopts corresponding countermeasures for various special reasons.
2. How to avoid filter desoldering?
For the metal mesh filter, when the ambient temperature is high, part of the oil temperature at the filter of the four-column hydraulic press is high, exceeding or close to the melting point of the welding point, plus the original welding is not strong, and the impact of the oil will cause desoldering. For example, the mesh filter at the inlet of the high-pressure plunger pump has been changed to silver solder many times, and their melting point has been greatly increased.
3. How to prevent the filter from falling particles?
The four-column hydraulic press refers to a metal powder sintered filter. After falling particles enter the system, the saving hole is blocked and the valve core is stuck. The reason is that the quality of the sintered powder filter is not safe. Therefore, a qualified sintered oil filter should be selected.
4. How to avoid filter clogging?
Generally, during the operation of the filter, the surface of the filter element will gradually heal, and it is normal to form a blockage. The blockage mentioned here is a serious blockage that knows that the four-column hydraulic machine is faulty. After the filter is blocked, at least poor oil pumping and pumping will occur. Noise, the system can’t suck in enough oil but the pressure can’t go up, there are many bubbles in the oil, and the filter element may be blocked due to the increase in pressure, which may cause a breakdown of the four-column hydraulic machine.
