Four column hydraulic filter function is to filter out the impurities mixed in the hydraulic oil and reduce the pollution of the oil in the system to ensure the normal work of the four column hydraulic press.The main fault of four column hydraulic filter is that the filtration effect is not good, and the oil can not be cleaned.

1. How to prevent the damage and deformation of the filter core?

The reasons for the damage of the filter core are: filter plug and error in selection. Elimination method: timely and regularly check cleaning oil filter; For four column hydraulic press, correctly select the filter with the capacity of pressure, strength and flow capacity to meet the requirements, and corresponding countermeasures are adopted for various special reasons.

How to prevent the filter from welding?

For the metal mesh filter, when the ambient temperature is high, the fourcolumn hydraulic press filter at the local oil temperature is high, beyond or close to the melting point of welding point, coupled with the original welding is not secure, the impact of oil will cause desoldering, for example, high-pressure plunger pump at the entrance of the mesh filter has repeatedly changed to silver solder, so as to improve the melting point greatly.

3. How to prevent the filter from falling particles?

Four column hydraulic press refers to metal powder sintered filter, when the falling particles enter the system, the throttle hole is blocked and the valve core is jammed, the reason is that the quality of the sintered powder filter core is poor, so a qualified burning oil filter is selected.

4. How to prevent the filter from clogging?

General filter in the course of work, the filter surface will gradually take over and cause clogging, which is a normal phenomenon. The blockage here is known as a serious blockage in four column hydraulic press. When the filter is blocked, at least it will cause poor pumping oil, noise from the pump, and pressure shortage caused by not enough oil absorbed by the system. A large number of bubbles in the oil and filter plugmay be the breakdown of the four column hydraulic press caused by the increase of pressure.
