1, the shock and vibration caused by loose fittings. When the hydraulic system, in a high state of motion, shock and vibration equipment is likely to make a Unit of the relevant joint loosening hydraulic system result in leakage events.

2, the safety valve on the distributor and oil return valve closed lax safety valve Dongguan hydraulic machine wear or too dirty hydraulic oil, oil return valve severe wear or too dirty because of hydraulic oil caused by the oil return valve closed lax.

3, high oil temperature and hydraulic seals and hydraulic oil incompatibility deterioration. High oil temperature is a common situation, the greater the depth from the ground, the oil temperature will be higher. Chemically stable PTFE material may also stand up to such a high temperature test, began defeated.

4, dynamic seals and fitting mutually wear. If this is the case, the hydraulic cylinder apparatus system more likely to cause. Although many hydraulic seals are used as tetrafluoroethylene material, but may still stand up to long-term friction out of the problem cylinder.

5, gear pumps relevant parts badly worn or incorrect assembly, oil pump gear pump housing with the gap exceeds a predetermined limit,

6, the hydraulic cylinder piston rod seal aging and damage to the lock nut loose, cylinder piston ring on the piston rod and piston seal retainer junction, hydraulic valve positioning ring damage.

Hydraulic machine hydraulic system leak of hydraulic machine of great harm. The part to be inspected regularly, timely detection and timely treatment maintenance. JETCO hydraulic machinery has come up with hydraulic system of the source of the problem why the total leakage, then we'll talk about the method of hydraulic leak handling hydraulic system, in the hope hydraulic machine problems you encounter help.

Troubleshooting Methods hydraulic system leak

1, or replace the pump casing using casement repair method, to ensure that the gap with the top gear pump and the housing within the specified range.

2, to ensure that the guide wire can simultaneously press the two bushings driven gear rotation direction by an angle so that two plane sleeve fit tightly.

3, if the compartment pressure hydraulic seals aging, should be replaced with new parts: relief sheet gasket should be installed on the suction chamber (port) side (low pressure chamber), and to ensure a certain degree of preload pressure. As pressure mounted on the liquid chamber side of the seal ring will soon damage, resulting in high pressure chamber communicates with the low pressure chamber, the hydraulic pump incapacity.

4, replace the hydraulic seal and seal retainer. Note, however, the choice of hydraulic seal surface should be smooth; no wrinkles, no cracks, no holes, no scratches.

5, less serious regret round can be taken to increase the replacement of hydraulic piston ring sealing its way to recovery; if roundness, cylindrical error when more than 0.05mm, the response cylinder honing processing, increased piston replacement to return to normal with the gap. system hydraulic seal

Hydraulic machine hydraulic system is the most important component, representing the heart of the hydraulic machine. If the hydraulic system leaks can cause fluid leaks, pollution of the surrounding environment, affecting work efficiency, increased production costs and so adversely affected. Control measures must be taken immediately. Now we understand why the total hydraulic system leak from the roots.

1, the shock and vibration caused by loose fittings. When the hydraulic system, in a high state of motion, shock and vibration equipment is likely to make a Unit of the relevant joint loosening hydraulic system result in leakage events.

2, the safety valve on the distributor and oil return valve closed lax safety valve Dongguan hydraulic machine wear or too dirty hydraulic oil, oil return valve severe wear or too dirty because of hydraulic oil caused by the oil return valve closed lax.

6, the hydraulic cylinder piston rod seal aging and damage to the lock nut loose, cylinder piston ring on the piston rod and piston seal retainer junction, hydraulic valve positioning ring damage.
