Oil water balance system of steel pipe hydraulic press

Hydraulic press is an essential equipment on the steel pipe production line, playing an important role in the quality inspection of steel pipes. Due to the fact that the water pressure value is a rapid, dynamic, continuous, and nonlinear growth process, it is very important to make the oil pressure value accurately and timely track the water pressure value, and always maintain a dynamic balance with the water pressure value. If the oil pressure is too high, it is easy to bend the steel pipe; If the water pressure is too high, it will cause the master cylinder to retreat and the pipe end seal to fail. In severe cases, it can cause high-pressure water to spray out, posing a safety risk to surrounding equipment and personnel. Through the optimization design of the electrical control system and hydraulic system, as well as the application of stable detection and executable components in the oil-water balance system of the hydraulic press main cylinder, the timely dynamic balance of oil pressure and water pressure has been well achieved.
