Four-column hydraulic press filter failure and solution

Four-column hydraulic press filter failure and solution

1. How to prevent the damage and deformation of the filter element

The reason for the failure and deformation of the filter element is: the filter element is blocked and improperly selected. Elimination method: Regularly check and clean the oil filter regularly. The four-column hydraulic press correctly selects the filter with pressure resistance, strength and flow capacity to meet the requirements, and take corresponding countermeasures for various special reasons.

2. How to prevent the filter from desoldering

For the wire mesh filter, when the ambient temperature is high, the local oil temperature of the filter of the four-column hydraulic press is too high, exceeding or close to the melting point of the welding point, and the original welding is not good, the impact of the oil will cause the welding to fall off. For example, the screen on the inlet of the high pressure plunger pump has been changed to silver solder several times.

3. How to prevent the filter from dropping particles

Most of the four-column hydraulic presses are metal powder filters. After the falling particles enter the system, the orifice is blocked and the valve core is stuck. The reason is that the quality of the sintered powder core filter element is not good, and a combustion-type oil filter that has passed the test should be selected.

4. How to prevent the filter from clogging

In the process of general filter, the surface of the filter element will gradually recover. Blockage is normal. The blockage described here is a severe blockage of a four-column hydraulic press. After the filter is clogged, at least the pump oil is not good, the pump makes noise, the system can't absorb enough oil, but the pressure doesn't go away. A large number of air bubbles appear in the oil, and the pressure of the filter element may be blocked due to the increase in pressure.
