In order to ensure product quality and excellent mechanical properties, each a hydraulic cylinder before leaving the factory must go through rigorous testing, to prevent the occurrence of the leak, get the customer the consistent high praise

 1, The use of some problems that should be paid attention to?

Attention should be paid to be prevent loose, prevent dust and prevent rust work.In long time stop work after to reuse, should pay attention to use a clean cotton cloth wipe the exposed surface of the piston rod.Startup no-load running first, after waiting for normal in articulated machines

2, Storage :

As spare parts of hydraulic cylinder suggested, stored in a dry, moist insulation and cannot have corrosion and corrosive gases.Should note add appropriate protective oil and hydraulic cylinder in and out of the oil should be strictly protect, avoid piston rod oxidation etch and mechanical damage

3, Large impact load cases:

Should pay close attention to the hydraulic cylinder bearing lubrication, check the axis of the situation in a timely manner to adjust the hydraulic cylinder or machine components centerline
