How to judge the hydraulic system performance of four-column hydraulic press?

The hydraulic system is the power system of the four-column hydraulic press. A complete hydraulic system consists of five parts, namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil. The quality of a hydraulic system depends on the rationality of the system design, the performance of the system components, the pollution protection and treatment of the system. The following is to popularize the method of judging the performance of the hydraulic system of the four-column hydraulic press.

First, the design of the hydraulic system, the design rationality of the hydraulic pump station will directly affect the stability of the entire system, whether the pipeline and line design is reasonable and safe, whether the arrangement is beautiful, and does not affect the performance of the machine. In addition, it is necessary to understand some basic configurations, the power and structure of the motor, the model of the valve block, the model of the hydraulic pump, the manufacturer of the sealing ring and electrical appliances and the manufacturer of the core electrical appliances are well-known enterprises.

Second, the weight of the four-column hydraulic press, to a certain extent, can also reflect the lighter service life of the hydraulic press, the machine is generally cheap for steel plate welding, the service life is short, and the failure rate is high. The heavier machine is cast as a whole, the overall performance is better, the service life is long, the rigidity is better, but the higher.

Third, the sensitivity of the hydraulic control valve response and the accuracy of the action of the hydraulic system is closely related to the order of the hydraulic system, to make the hydraulic system action accurate and orderly, must choose high-quality hydraulic control valves, especially to select a variety of directional valves and sequence control valves, the failure of these valves will inevitably cause the hydraulic system order chaos.

We can judge whether the hydraulic system of the four-column hydraulic press has the accuracy through the above three points, and pay special attention to the purchase of the hydraulic system, so as to meet the load requirements of the hydraulic system and ensure that it fully plays its due effect.
