What is the main reason for the low efficiency of four-column hydraulic presses?

There is gas in the hydraulic cylinder of the four-column hydraulic press. If the four-column hydraulic press moves slowly, the main consideration is the air entering the hydraulic cylinder. Pay attention to whether there is air entering in the direction of the hydraulic cylinder, which depends on the actual operation of the equipment's exhaust pipe mechanical equipment to interrupt the corresponding exhaust pipe. If so, the sealing ring may be defective and needs to be replaced in time.

Check whether the hydraulic four-column hydraulic pump in the four-column hydraulic press is running slowly, whether the hydraulic oil pump is born irregularly, and sometimes there are obstacles or slight death, indicating that there is a problem with the hydraulic oil pump and needs to be repaired or replaced in time.

Check the completion of the piston rod of the four-column hydraulic press. If the reverse start of the hydraulic cylinder of a four-column hydraulic machine is interrupted, the piston rod may be temporarily interrupted, causing the four-column hydraulic machine to run slowly. The main reason is that the throttle valve nozzle is too small, which reduces the amount of oil entering the equipment buffer cavity. If this shortcoming occurs, the throttle valve nozzle should be increased and the remaining oil entering the buffer chamber should be added.
