The explosion-proof vibrator EVV-12-25 is used in the coal, oil refining, gas, chemical industry and other industrial areas where there may be an explosion hazard. The main difference of this vibrator model is the explosion-proof housing, which eliminates the possibility of fire in hazardous environments.
The principle of operation
The explosion-proof vibrator EVV-12-25 is an asynchronous motor, which requires a voltage of 380V to operate. At the ends of the shaft there are adjustable balances in three positions. The vibration that occurs when the shaft moves is transmitted to the structure where the vibrator is located. The principle of operation of the device of this model practically does not differ from general-purpose vibrators, the difference is only in an increased level of protection against fire. The driving force ranges from 6.1 to 12.3 kN, the synchronous rpm is 1500 per minute, and the working life is 5000 hours. The security level of IP66 is regulated by GOST.
