Why Is There A Lack Of Pressure On The Chrome Plated Steel Bar?

- Aug 21, 2019-

1) The oil does not enter the hydraulic cylinder.

 

1 The reversing valve is not reversing.

 

2 The system is not supplied with oil.

 

2) Although there is oil, there is no pressure.

 

1 The system is faulty, mainly because the pump or the relief valve is faulty.

 

2 The internal leakage is serious, the piston and the piston rod are loose, and the seal is seriously damaged.

 

3) The pressure does not reach the specified value.

 

1 The seal is aging and fails, and the seal lip is reversed or damaged.

 

2 Piston ring is damaged.

 

3 system setting pressure is too low.

 

4 The pressure regulating valve is faulty.

 

5 When the flow rate of the regulating valve is too small, when the leakage amount in the hydraulic cylinder increases, the flow rate is insufficient, resulting in insufficient pressure.
