The explosion-proof vibrator EVV-20-50 is designed for use in areas where there is a possibility of fire or explosion. Thus, the EVV-20-50 model is widely used in the chemical, gas, oil refining, and coal industries. Fire protection is provided by the special material of the vibrator body. The model is mainly used on vibrating plates, vibrating screens and other vibrating equipment.
The principle of operation
The mechanism of operation of an explosion-proof vibrator is no different from general-purpose devices. For the EVV-20-50 to work, it is necessary to connect it to a network with a voltage of 380V. The driving force transmitted from the rotor shaft of an asynchronous electric motor creates vibration, which is sent to the surface of the vibrator placement. The unbalances are covered from the outside with protective covers, which can be attached both to a stud and to bolts. The driving force can range from 9.9 to 20.0 kN. The working life reaches 3000 hours.
