Hydraulic cylinder manufacturer Use and maintenance of equipment

I) Hydraulic cylinder Basic Requirements

Use HM-32 (32 # anti-wear hydraulic oil) in winter,

1. The recommended working fluid is HM-46 in summer or machine oil with corresponding viscosity (kinematic viscosity 30 centistokes to 40 centistokes at 50 ° C) to avoid accelerated aging of seals.

2. The oil temperature shall be between 5 ° C and 65 ° C during operation The oil pollution index should be in the 19/16 level of the specification.

3. Ensure that the hydraulic oil is clean.

2） Packaging, storage and transportation

The junction surface of the oil port and the exposed part of the piston rod shall be equipped with protective devices.

one Hydraulic cylinder Appropriate packaging shall be added during storage and transportation. Prevent bumping.

2. It shall be firmly fixed during storage and transportation. Avoid falling.

3. When lifting, it shall be fastened firmly.

3） Disassembly and assembly of hydraulic cylinder

The oil pressure in the hydraulic cylinder circuit should be reduced to zero.

1. Before assembling the hydraulic cylinder.

2. The parts of the hydraulic cylinder shall not be damaged during assembly. The assembly sequence is also different,

3. The specific structures of hydraulic cylinders are different. It should be judged according to the specific situation.

The flange connection screws shall be removed first. Use screws to push out the end cover. Do not pry or hammer hard to avoid damage.

Special tools shall be used for internal bayonet connection. Push the guide sleeve inward to expose the key. After the key is removed from the light wallboard, fill the key slot with nylon or rubber material, and then remove it.
