How to control the hydraulic cylinder leakage incident?

1 never hurt

Hydraulic system leakage influences the mission system safety, the hydraulic cylinder form oil waste, purification surrounding environment, increase the restart time machine, the decline in the ratio of consumption, to add consumer rest on our laurels and fouling on the formation of the products and so on the hydraulic system leak we must grasp.

2 the cause of leakage

Almost all of the hydraulic system leakage is after using a period of time because of the following three causes: (1) shock and vibration form pipe joint is loose; (2) dynamic sealing parts and fittings mutual wear (hydraulic cylinder especially); (3) high temperature and rubber sealing and hydraulic oil incompatible metamorphosis.

3 grasp the way out

(1) increase the impact and vibration

In order to increase the pipe joint suffered shock and vibration caused by loose leakage of Q345E steel plate, can take the following measures:

The use of shock absorber bracket fixed all the tubes for the shock and vibration;

Use low impact valve or accumulator to increase impact;

Proper arrangements for the pressure control valve to cover all the components of the system;

Try to add the number of the pipe joints, pipe welding joint as far as possible;

The use of straight thread joint, three joint and elbow replacement tapered pipe thread;

We try to use the oil return block instead of all piping;

Seventhly, for the use of the lowest pressure, rules installation using torque of the bolt and plug torque, to avoid joint surface and a sealing member is swallowed up;

The accurate installation of pipe joints.
