The reason why the pressure of the hydraulic press cannot rise

1. The hydraulic gauge is broken, replace it with a new hydraulic gauge;

2. The hydraulic machine is leaking oil. First, carefully check whether there is any obvious oil leakage on the surface of the machine (hydraulic cylinder, hydraulic pipeline that has a connection effect); if not, then the oil seal of the piston is damaged. Put this around first , Because unless it is really impossible to find a solution, the hydraulic cylinder will be disassembled to replace the sealing ring of the oil seal;

3. Common sense operation error. Although this phenomenon is relatively simple, it should also attract the attention of hydraulic press operators. For example, the three-phase connection is reversed, the height of the oil in the fuel tank cannot reach the specified value, and the pressure regulating valve has not been adjusted to increase the pressure (that is, The relief valve is not adjusted properly). This phenomenon usually occurs when the new employee uses the hydraulic press for the first time;

4. If the hydraulic valve is broken, the valve is blocked, the internal spring is stuck by impurities, and it cannot be reset, the pressure of the hydraulic press cannot be increased. If it is a manual reversing valve, remove it and wash it. Unscrew the screw, take out all the parts inside, wash it again, blow the valve with an air gun, and put it back in sequence); if it is an integrated hydraulic valve, you need to disassemble the corresponding hair block to check and clean it. It can be installed according to the original method;

5. The power of the hydraulic machine is not good. Generally, it appears on the older machines, either the hydraulic pump is worn out, or the motor is aging. At this time, you can put your palm on the outer wall of the oil inlet pipe (that is, the pipe connecting the hydraulic pump to the oil tank), start Hydraulic machine, if the suction force of the machine is very large, the hydraulic pump will be no problem, otherwise there will be problems; the aging of the motor is relatively rare, if the motor is really aging, there will be a lot of noise, because the motor cannot carry the oil pump, the occurrence of The motor is suffocated, so the sound will be loud.
