　　Open and close air damper winchJMB-4Type Overview:

　　Open and close air damper winchJMB-4typeIt consists of six main parts: explosion-proof motor, coupling, transmission gear, worm gear reducer, drum, and base. The drum is driven by a worm gear reducer through a pair of transmission bevel gears driven by an electric motor. The support of the transmission parts and the worm gear use sliding bearings, while the worm gear uses rolling bearings. The worm has self-locking function to prevent the steel wire rope from sliding down. This machine is driven by an electric motor, but it can also be manually driven when the power is temporarily cut off or there is no power available.

　　The JMB-4 type air damper winch is driven by an electric motor, but it can also be manually driven when temporarily cut off or without power supply.

　　Open and close air damper winchJMB-4typeOperation, maintenance, and safety technology

　　1. Operation of the winch for opening and closing the air door:

　　When operated by hand, swing the hand to rotate the winding drum through the worm gear and worm wheel, winding the steel wire rope for work.

　　When driven by a motor, the drum rotates and wraps around the steel wire rope through a coupling, cylindrical gear, worm gear, and worm wheel for operation. Due to the fact that the helix angle of the worm is smaller than the friction angle, it has self-locking properties, so the air door will not fall due to its own weight when stopping during opening and closing.

　　During the operation of the winch, it is necessary to regularly inspect all fastening parts to prevent looseness. In case of abnormal operation, the winch should be stopped and inspected in a timely manner to eliminate it. The maintenance cycle of the winch can be determined according to the specific situation, and the wear and tear of the main parts should be recorded during maintenance. Damaged parts should be repaired or replaced in a timely manner. Attention should be paid to the lubrication of the winch regularly. No. 20 gear oil (HL-20) should be injected into the cylindrical gear and worm gear reducer, and No. 3 calcium based grease (ZG-3) should be used for other lubrication points.
