How should the hydraulic oil press do not boost the pressure?
One is caused by sundries being sucked into the oil pump, so that the steel ball in the oil inlet valve can not be restored to its original position; This requires that we must pay attention to the maintenance of the hydraulic oil press when we are usually in use, and regularly filter or replace the hydraulic oil.
Two points is the low pressure pump inside the air entry, which belongs to the error of operation, this needs to remove the gear pump tubing, and then start the hydraulic oil press. Drain the oil from the pipe. Reset it again.
The three points are the oil seal damage in the oil cylinder, which is generally caused by long time wear and tear. It only needs to be replaced with a new oil seal.
The four points are that the pressure damage can not show whether the pressure is rising. The main reason for this situation is man-made, because some users want to increase the pressure to extract more oil, so they adjust the pressure to more than 60Mpa, which is beyond our regulation of 55Mpa pressure, which is very easy to damage the pressure gauge.
