Construction diagram of pneumatic clutch
In the past, the drive motors (using synchronous motors) of large domestic grinding machines were connected to the grinding machines through couplings, and the grinding machines and motors started simultaneously. Due to the influence of the torque generated by the bias between the grinding medium and the material in the grinding machine in a static state, the installed power of the grinding machine connected by the coupling is much higher than the actual operating power. The energy waste of driving the motor "big horse pulling small car" is very serious. The starting current of the motor is generally 3-7 times the rated current, and the starting process of large grinding machines is usually longer. If a coupling connection is used for direct starting, the entire power grid and motor must withstand the impact of high starting current during the entire process of starting the grinding machine: for units with smaller electrical device capacity, it will seriously affect the operation of other equipment; For units that frequently stop and start frequently, the service life of the electric motor will be greatly reduced, causing unnecessary losses to users' production. The grinding machines produced by our factory use pneumatic clutches to solve the starting problem of such large ball mills. The connection method of directly starting the motor coupling grinding machine is changed to the connection method of starting the motor pneumatic clutch grinding machine in different time periods. The motor is started with no load, and then the pneumatic clutch is inflated to start the grinding machine. This is currently the most ideal method to solve the starting problem of large grinding machines. It can start the grinding machine with one inflation, or slowly rotate the ball mill for a certain purpose. This product is suitable for mechanical equipment driven by various high-power motors or internal combustion engines in mining, petroleum, chemical, power, metallurgy, shipbuilding, and other industries.
