Anti-surge device for parallel air blowers

The anti-surge device comprises a supporting plate provided with a motor and two air blowers, the motor is arranged between the two air blowers, and the output end of the motor is connected with the input ends of the two air blowers through a transmission system so as to control the two air blowers to work synchronously in the same direction; one motor is used for transmitting power to the two air blowers connected in parallel through the gear transmission system and the chain transmission system, so that the two air blowers keep synchronous operation, and the surge phenomenon caused by different rotating speeds of the two air blowers is avoided. According to the parallel-connection air blower, the air opening pressure adjusting device is installed at the inlet of the air blower, in the using process of the air blower, due to the problems of working conditions, blade abrasion and the like, the pressure intensity of two outlets is unequal and inconsistent, the surge phenomenon can be generated, and according t
