Pneumatic clutch is one of the important transmission components of oil drilling rigs and oil workover rigs. It is used to transmit torque and disengage the transmission system during the work of drilling rigs and workover rigs.
Its main functions are: (1) to transmit torque in the power transmission system; (2) to act as a clutch and transmit torque in the pump set; (3) to be used as an air-controlled brake in special working conditions.
