How to repair and maintain hydraulic fittings?

First, daily maintenance

1. Working oil is recommended to use anti-wear hydraulic oil No. 32 and No. 46, and the oil temperature is in the range of 15 to 60 degrees Celsius.

2. The oil is strictly filtered before being allowed to be added to the fuel tank.

3. The working oil is replaced every year, and the first replacement time should not exceed three months;

4, the slider should always be lubricated, the appearance of the column should be kept clean, and the oil should be injected before each work.

5. The maximum allowable eccentricity of 40mm under the nominal pressure of 500T. Excessive eccentricity can cause strain on the column or other undesirable phenomena.

6. Check the pressure gauge once every six months;

7. If the machine is out of service for a long time, the surface of each added part should be cleaned and coated with anti-rust oil.

Two: safety operations

1. Those who do not understand the structural performance of the machine or the operating procedures should not start the machine without authorization;

2. The machine should not be repaired and adjusted during the working process;

3. When the machine finds serious oil leakage or other abnormalities (such as unreliable operation, loud noise, vibration, etc.), it should stop to analyze the cause, try to eliminate it, and do not bring disease into production:

4. Do not overload or exceed the maximum eccentricity:

5. It is strictly forbidden to exceed the maximum stroke of the slider. The minimum mold closing height shall not be less than 600mm.

6. Electrical equipment grounding must be firm and reliable:

7. End of work every day: Put the slider to the lowest position.
