Maintenance of four column hydraulic press

Jul. 08, 2020

Four column hydraulic press common faults and maintenance methods: often in the hydraulic transmission system, are some of the more precise parts. Although people feel that the hydraulic transmission of machinery is labor-saving and convenient, it is easy to be damaged at the same time. There are three basic "pathogenic" factors in hydraulic system: pollution, overheating and air entering. These three unfavorable factors have close internal relations. If any one of them appears, another one or more problems will arise. It has been proved by practice that 75% of the four column hydraulic press system is caused by these three factors. 1. Solution: the cleaning and assembly of some main precision parts in the system should be carried out in a very clean room. There should be clean floors and closed doors and windows in the room. The temperature should be kept at about 20 ° C.

Other common maintenance:

1. When l-hl32 / gb1118-89 hydraulic oil is lower than 20 ℃, N46 / gb3141 can be used when the pressure is higher than 30 ℃.

No. 32 and No. 46 anti-wear hydraulic oil are recommended for working oil, and the oil temperature is within 15 ~ 60 ℃.

2. The oil is allowed to be added into the oil tank after strict filtration.

3. The working oil should be changed once a year, and the first time should not exceed three months;

4. The sliding block shall be filled with lubricating oil frequently, and the surface of column surface shall be kept clean, and the oil shall be sprayed before each operation.

5. Under the nominal pressure of 500t, the maximum allowable eccentricity of concentrated load is 40mm. If the eccentricity is too large, the column will be strained or other undesirable phenomena will appear.

6. Calibrate and check the pressure gauge every half a year;

7. If the machine is out of service for a long time, the surface of each processing plant should be cleaned and coated with antirust oil.
