Maintenance and safe operation of the hydraulic brick machine

Maintenance and safe operation of the hydraulic brick machine

Maintenance

1. It is recommended to use No. 32 and No. 46 anti-wear hydraulic oil for working oil, and the oil temperature should be within the range of 15 to 60 degrees Celsius.

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

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

4. The slider should always be filled with lubricating oil, the exposed surface of the column should be kept clean frequently, and oil should be sprayed before each work. ​​

5. The maximum allowable eccentricity of concentrated load is 40mm under the nominal pressure of 500T. If the eccentricity is too large, it is easy to strain the column or cause other undesirable phenomena. ​​

6. Calibration and inspection of the pressure gauge every six months;

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

Safety operation matters

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

2. During the working process of the machine, the overhaul and mold adjustment should not be carried out;

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

4. Do not overload or exceed the maximum eccentric distance:

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

6. The grounding of electrical equipment must be firm and reliable:

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