column information in the field of hydraulic machinery, relying on friends [20 years] industry deep plowing experience, focus on the output of hydraulic technology innovation, market trends, application cases and other high value content. With the aim of "professional, timely and deep", we provide one-stop information service for engineers, purchasing decision makers and industry researchers, helping users to accurately grasp the pulse of hydraulic technology development.
1. Check whether the oil inlet pipe of the plunger pump of the 630-ton hydraulic press sucks in air, causing the pump to have large noise, vibration and pressure fluctuation. to prevent the pump due to poor sealing, suction pipe resistance (such as bending too much, pipe is too long) caused by inadequate suction, suction into the air...

In general, during the operation process of the filter of the four-column hydraulic press, the surface of the filter element will gradually become blocked by dirt, which will lead to problems in the hydraulic system. After the filter is blocked, it will lead to poor oil absorption by the pump, noise, and the system cannot absorb the oil that meets the requirements, thus causing pressure...

The speed control circuit of the hydraulic system of the four-column hydraulic press is the core circuit. The selection of the hydraulic circuit must start from the selection of the speed control circuit (including the circulation form of the oil circuit and the structure of the oil source). One: speed control circuit. according to the hydraulic actuator working condition diagram...

The function of overflow valve of 400-ton hydraulic press The overflow valve of 400-ton hydraulic press has two types: direct effect type (direct acting type) and pilot type. The overflow valve ensures that the pressure in the hydraulic system is a certain value by spilling part of the oil to the oil tank and avoids the system...
