How to quickly separate the oil air in the oil tank of a four-column hydraulic press

The utility model relates to a mechanical equipment for processing metal, plastic, rubber, wood, powder and other products by using the static pressure of hydraulic oil transported by oil pump. When the four-column hydraulic press is working, many problems such as pump noise, cavitation and cylinder crawling will occur due to improper sealing. Today, Xiaobian will introduce you how to solve the phenomenon that the oil air bubble in the oil tank is difficult to separate?

1. Set a separator to separate the oil return area from the oil suction area of the pump. This measure can make the return oil deflected by the separator, slow down the flow rate of the oil, which is conducive to bubble separation and overflow of the oil surface, but this way is difficult to separate fine bubbles, and the separation efficiency is not ideal.

2, when the staff set the metal mesh, install a metal inclined mesh at the bottom of the tank, and use a 60-mesh mesh to defoaming, then the effect will be the best state.

3. When the air filter on the box cover is blocked by dirt, it is difficult to separate from the air, which will also lead to negative pressure in the tank due to fluctuations in the oil surface of the tank during the working process of the hydraulic system, making the pump suck poorly. At this time, the cleaning air filter should be disassembled.

4. In addition to the use of hydraulic oil with good defoaming performance, the following measures can also be taken to remove the possibility of bubbles generated by the return oil mixing and remove bubbles. After the return oil is decelerated by the spiral flow chute, the oil tank will not stir and produce bubbles; The metal mesh has the effect of trapping air bubbles and removing them. This method is very effective for the separation of oil and air bubbles in the four-column oil press tank.
