In the working parts of hydraulic mechanical devices, usually very low speed is required. Similar problems occur during the operation of the four-column hydraulic press, which is a low-speed stability problem. For the four-column hydraulic press, the operation will cause great harm and must be eliminated, but it is still running , The failure phenomenon is different, regular operation, regular operation, some irregular operation; large amplitude, some operation occurs at a very low speed.
Because the four-column hydraulic press produces this kind of operation, the reasons are different planes, some are mechanical, some are hydraulic, some are mainly caused by inflow air, and some are caused by poor lubrication. Professional designers should continue to summarize and summarize. Quickly find out the cause of the corrosion. In addition to the guide of the four-column hydraulic machine does not meet the requirements, there are also hydraulic cylinder problems of the machine, such as the hydraulic cylinder axis and the guide rail are not parallel, the hydraulic cylinder hole restriction section corrosion and tensile damage, etc., therefore, Effectively reduce pressure shock and prevent noise pollution.
In order to fundamentally improve the operating efficiency of the four-column hydraulic press, the design, production and installation of the guide rails and hydraulic cylinders must be carried out in accordance with the standards. At the same time, in the later use process, the maintenance and maintenance of the machine must be carried out. The top position has a support function to safely take out the pressed workpiece, reduce work intensity and improve work efficiency. The system has a pre-unloading function to release the pressure of the main cylinder of the four-column hydraulic machine in advance.
When the hydraulic cylinder is lifted up by the four-column hydraulic machine, due to the self-weight of the hydraulic cylinder, the downward speed is fast, and the upper part of the four-column hydraulic machine may have a vacuum phenomenon. You can quickly replenish the oil through the suction valve. The filter device of the four-column hydraulic machine and the oil temperature are too high to detect the quality of the oil in time And temperature to prevent abnormalities in operation.
