The importance of installing filters in four-column hydraulic presses

Why should a filter be installed in a four-column hydraulic press? What is its importance? Here is to introduce the importance of installing filters in the four-column hydraulic press as follows:

First, installed on the suction pipe of the hydraulic pump of the four-column hydraulic press, maintain the hydraulic pump. The request for oil can be large, the resistance is small, and the coarse filter is usually used (function: filter impurities, etc.).

Second, installed on the four-column oil press return circuit to ensure that the oil in the return tank is cleaned, and can be used as a low pressure filter (function: filter impurities, etc.).

Third, installed on the four-column hydraulic press oil supply pipeline, maintain other hydraulic components except hydraulic pump. Request the filter element and the shell to withstand high pressure, installed after the relief valve or in parallel with the safety valve (function: control pressure does not exceed the specified value), the open pressure of the safety valve should be slightly lower than the filter (function: filter impurities, etc.) the allowable pressure difference, there is a fashion clog indicator. The filter allows a large pressure drop.

Four, installed in the four-column hydraulic auxiliary pump oil transmission road. Some Tengzhou four-column hydraulic press closed hydraulic system auxiliary oil circuit, auxiliary hydraulic pump working pressure is low, usually as long as 0.5, the fine filter (function: filter impurities, etc.) installed in the auxiliary pump oil pipeline, to ensure that impurities do not enter the hydraulic components of the main oil circuit

Five, installed in the four-column hydraulic press tributary pipe, reduce the filter (function: filter impurities, etc.) through the flow (unit: cubic meters per second), belongs to the partial filtration, there are many ways, applied to the open loop pump flow larger situation, in the important hydraulic components to install precision filter.
