1) basic requirements for hydraulic cylinders: hm-32 (32# anti-wear hydraulic oil) should be used in winter.

As follows: 1. It is recommended to use working liquid in the summer to use HM - 46. Or use the corresponding viscosity of machine oil (50 ° C, the kinematic viscosity 30 mile to stoke stoke to 40 department)

To avoid accelerated aging of seals.

2. When you are working oil temperature should be between 5 ° C to 65 ° C. Oil pollution index should be in the national standard of 19/16.

3. Keep the hydraulic oil clean.

Packaging, storage and transportation

Protective device should be added to the oil joint surface and the exposed part of piston rod.

1. The corresponding packaging should be added during the storage and transportation of the hydraulic cylinder. Prevent bump.

2. It shall be firmly fixed during storage and transportation. To avoid collision.

3. The rope should be fastened firmly when lifting.

Disassembly and assembly of hydraulic cylinders

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

1. Before assembling the hydraulic cylinder.

2. Avoid damaging the parts of the hydraulic cylinder during assembly.

The order of assembly is not the same,

3 due to the specific structure of the hydraulic cylinder is not the same. Judge according to the specific situation.

Flange connection screw should be removed first, flange connection type. Use screws to push the end cover out. Do not pry or hammer to avoid damage.

Should use the special tool, the inner card key type connection. After the guide sleeve is pushed inward to expose the key, the light weight wallboard will remove the key and fill the key slot with nylon or rubber materials before removing it.

The screw gland should be unscrewed first. Threaded oil cylinder.

Do not force the piston rod assembly out of the cylinder, remove the piston rod and piston. Try to hold the piston rod assembly and the cylinder shaft in a line drawn out slowly.

Parts should be kept in a clean environment, and installed to prevent bump isolation device, before re - assembly

4. After parts are removed and inspected. Parts should be cleaned.

4) requirements of working environment

The appearance of the hydraulic cylinder should be rustproof.

Wind and rain.

Insulation shall be provided around the hydraulic cylinder.

2. When working in high temperature environment.
