Abstract

The invention discloses a condensate pump, The pump comprises a pump body, an impeller arranged in the pump body and a pump cover connected with the pump body, a liquid inlet is formed in the pump cover, a pump body liquid outlet is formed in the pump body, a backflow control valve is arranged at the position of the pump body liquid outlet, a liquid outlet and a backflow opening are formed in the backflow control valve, and a backflow assembly is arranged between the backflow opening and the liquid inlet. The condensate pump has the backflow function, cavitation can be delayed, and the net positive suction head is reduced.

Description

technical field [0001] The invention relates to the technical field of delivery pumps, in particular to a coagulation pump. Background technique [0002] For traditional condensing pumps, when the working conditions change, the flow rate into the pump becomes smaller and the pressure becomes lower, while the impeller rotates continuously to increase the water temperature in the pump, which will induce pump cavitation. When cavitation occurs in the pump, it will affect the parameters of the pump, and even cut off the flow in severe cases. At the same time, the vibration of the pump rotor may cause damage to pump parts. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a condensation pump with a backflow function, which can delay cavitation and reduce NPSH. [0004] In order to solve the problems of the technologies described above, the present invention adopts the foll...
