Hydraulic machinery maintenance system

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 it is allowed to be added to the tank. 3. The working fluid is replaced every year, and the first replacement time should not exceed three months; The slider should always be lubricated. The appearance of the column should always be kept clean. The oil should be injected before each work. 5. At a nominal pressure of 500T, the concentrated load is allowed to eccentrically 40mm. 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 wiped clean and coated with anti-rust oil. II: Safety operation matters 1. Those who do not understand the structural performance of the machine or the operating procedures should not start the machine without authorization; 2. During the working process, the machine should not be repaired and adjusted; 3. When the machine finds serious oil leakage or other abnormalities ( If the action is unreliable, noise, vibration, etc., stop the analysis of the cause, try to eliminate it, and do not bring the disease into production: 4. Do not overload or exceed the maximum eccentricity. 5. Do not exceed the maximum stroke of the slider, the mold closing height The minimum must 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.
