Automotive air conditioning clutch installation and use of precautions:
● The car air conditioner clutch must be cleaned before installation to remove rust-proof grease and sundries.
● Clutch can be installed coaxially or sub-axis. The axial direction must be fixed. The axial movement of the driving part and the driven part are not allowed. When the sub-axle is installed, the coaxiality between the driving part and the driven part shaft Should not be greater than 0.lmm.
● When working in wet air-condition electromagnetic clutch, the lubricant must be added between the friction plates. Lubrication method adopts (1) sub-oil lubrication; (2) oil-bath lubrication, the part immersed in oil is about 5 times of the clutch volume; (3) Axial lubrication, high-speed and high-frequency action should be used when the axis of oil supply method.
● When installing the jaw clutch, it is necessary to ensure that there is a certain gap between the end teeth so that there is no grinding phenomenon during idling, but the value should not be greater than δ.
● Automotive air conditioning electromagnetic clutch and brake for Class B insulation, normal temperature rise 40 ℃. Limit the thermal equilibrium operating temperature does not allow speeding 100 ℃, otherwise the coil and the friction part of the damage prone.
● power and control lines, automotive air conditioning clutch DC 24 V DC (except for special orders). It is by the three-phase or single-phase AC voltage step-down and full-wave rectifier (or bridge rectifier) get no regulation and smooth wave required power is large enough. Not allowed to use half-wave rectifier.
