Building Slab Forming MachineHydraulic System [monthly Maintenance Items]
1、 Oil TypeCheck The Hydraulic Oil Level And Add Anti-wear Hydraulic Oil Of The Same Grade If It Is Insufficient. Mixing Is Strictly Prohibited.Observe The Color Of The Oil: White, Black, Turbid, With Impurities Settling, Change The Oil In Advance.Check The Normal Oil Temperature: The Normal Working Oil Temperature Should Be Between 30-60 ℃, And If It Exceeds 65 ℃ For A Long Time, Check The Heat Dissipation And Overflow Valves.2、 Filter Element And Oil CircuitCheck/replace The Return Oil Filter And Suction Filter, And Replace Them Directly If They Are Severely Clogged.Check The Oil Pipes And Joints For Oil Leakage, Bulging, Aging, Bending And Oil Holding, And Tighten The Loose Joints One By One.System Exhaust: Exhaust The Oil Cylinder And Pipeline To Eliminate Vibration And Response Lag.3、 Valve Group And PressureClean The Dust And Oil Stains On The Surface Of The Solenoid Valve, And Check Whether The Wiring Terminals Are Loose Or Oxidized.Verify System Pressure: Fine Tune The Pressure Of The Overflow Valve Again, Confirm That The Cut-off Pressure Is Stable, Not Too Low, And Does Not Overflow Or Release Pressure.Check The Action Of The Solenoid Valve: Check Whether The Direction Change Is Sensitive, Whether There Is Any Jamming Or Delay.4、 Oil Cylinder And Mechanical PartsCheck And Cut Off The Piston Rod Of The Oil Cylinder For Any Signs Of Strain, Oil Leakage, Or Damaged Dust Cover.Add Lubricating Grease To The Guide Rails And Sliding Parts Of The Tool Holder To Eliminate Hydraulic Hysteresis Caused By Mechanical Resistance.Check The Gap Between The Knife Holder And The Fixing Screws Of The Blade, And Tighten Any Loose Parts.5、 Electrical And AuxiliaryCheck The Running Sound Of The Hydraulic Motor And Oil Pump For Any Abnormal Noise Or Vibration.Clean The Dust From The Hydraulic Oil Tank Cooling Network/cooler To Ensure Effective Heat Dissipation.Tighten All Fixing Bolts And Feet Of The Hydraulic Station To Prevent Loosening Due To Vibration.6、 Record MaintenanceRecord The Operating Status Once A Month, Including Oil Temperature, Pressure, Leakage, And Smooth Operation, To Facilitate Early Prediction Of Faults.
