Exhaust device of universal four-column hydraulic press

When the four-column hydraulic machine vibrates or crawls, it is mostly due to the air being mixed into the hydraulic system and it cannot operate normally. The air must be discharged from the cylinder as soon as possible.

In the hydraulic system of a universal four-column hydraulic machine, the selection of auxiliary equipment is also important. Sometimes the selection of auxiliary equipment is unreasonable or the quality is not good, causing the system to produce oil leakage, vibration and noise, oil overheating, and excessive oil content. Phenomena such as gas and various impurities will pollute the working environment, seriously damage the working ability of the hydraulic system, and even cause accidents. Therefore, the position of auxiliary equipment in the high-performance, high-index hydraulic transmission system is very important.
