A few days ago, AVIC Jiaye (Beijing) Technology Co., Ltd. successfully developed the XB cyclone centrifugal constant pressure pump, and passed the scientific and technological achievements appraisal organized by the Beijing Municipal Science and Technology Commission. Experts believe that the product has independent intellectual property rights, and its main performance indicators have reached the world's leading level.
Swirl Centrifugal Constant Pressure Pump is a new type of pump with constant pressure characteristics for liquid delivery. Constant pressure transmission medium is required by various working conditions. For example, high-rise domestic water supply and fire protection require constant pressure. Chemical reactions in chemical processes require constant pressure, and long-distance oil transportation also requires constant pressure. According to reports, the centrifugal centrifugal constant pressure pump developed by AVIC Jiaye Company has been developed based on the principle of the joint action of centrifugal and swirling. It can provide high lift of low specific speed centrifugal pump and constant pressure characteristics of the swirl pump. The pump adopts the features of swirling and centrifugal pumps to design new impellers, uses centrifugal pump volutes modified according to swirling requirements, and adopts the optimum suction chamber design of centrifugal pumps to modify the swirling pump suction chambers. , Compared with the performance of centrifugal pump lighter than 1/3. The pump has the characteristics of constant outlet pressure, small starting torque, low noise, small vibration, high efficiency, compact structure, convenient installation and maintenance.
It is reported that the pump currently has seven types of horizontal type, vertical type, horizontal type self-priming, micro horizontal type, micro vertical type, micro self-priming and horizontal type matching with the motor, and the highest head can be matched with the motor. Up to 200 meters to 250 meters, the maximum flow of 100 liters / second, the maximum diameter of 200 mm. The pump can also be designed according to the actual needs of the production of submersible, multi-stage, single-stage double suction and other types of cyclone centrifugal constant pressure pump.
