Location of filter equipment for four-column hydraulic press

Where is the position of the filter equipment of the four-column hydraulic press? The following Xiaobian will introduce you to the equipment location of the four-column hydraulic press filter as follows:



First, the equipment is in the four-column oil press return circuit. The characteristic of the equipment method is that the strength of the filter element of the four-column hydraulic press is low, and the fine oil filter can be selected, but it can not directly prevent the impurity particles from entering the system, but improve the cleanliness of the oil in the four-column hydraulic press tank by continuous circulation. In order to avoid the problem caused by the blockage of the four-column oil filter, a back pressure valve can be connected with the oil filter in parallel to create a safety effect.

Two, four column hydraulic pump outlet or fine hydraulic components. This method has a good maintenance effect on the system and components of the four-column hydraulic press. The filter with high filtration accuracy (degree) and good impact resistance can be selected. The oil filter has high pressure, and the pressure loss is generally less than 0.35MPa. It is often used in systems with high filtration accuracy (degree) requirements and before servo valves and speed regulating valves.

Three, four column hydraulic press independent filtration system. In the large hydraulic system, in addition to the system's own equipment has a general oil filter, other hydraulic systems have no independent filtration system, high filtration accuracy (degree), through continuous circulation, improve the cleanliness of the oil. The special oil filter truck is also an independent filtration system, which is used to filter and periodically filter the oil in the tank when refueling the equipment.

Fourth, the equipment is in the suction port of the four-column oil press pump. The method can directly prevent large particles from entering the hydraulic pump of the four-column hydraulic press. The four-column oil press is required to be more than twice the flow rate of the hydraulic pump (unit: cubic meters per second), the pressure loss is less than 0.01 ~ 0.035MPa, and the filtration accuracy (degree) is low.
