Water pump capable of controlling flows

Abstract

The invention discloses a water pump capable of controlling the flows. A base is connected with a motor cylinder and a pump body sealing ring through fixing pieces; a wireless variable frequency controller is arranged in the motor cylinder and is connected with a motor; the motor is connected with an impeller through a pump shaft; a coupler is arranged on the pump shaft; a bearing is arranged on the right side of the coupler and is arranged in the pump body sealing ring; the pump body sealing ring is connected with a right side pump cover; an impeller sealing ring is arranged in the pump cover; the impeller connected with the pump shaft is arranged in the impeller sealing ring; a mechanical sealing device is arranged between the pump cover and the pump body sealing ring; a water outlet isformed above the pump cover; and a water inlet is formed in the right side of the pump cover. The invention aims to solve the technical problem so as to provide the water pump capable of controlling the flows. The output frequency of the motor can be adjusted through the wireless variable frequency controller, so that an effect on changing the water outlet speed through controlling the rotating speed of the impeller is achieved; and meanwhile, the flows of the water outlet and the water inlet can be directly adjusted through a controllable valve.

Description

technical field [0001] The invention relates to a water pump device, in particular to a flow-controllable water pump. Background technique [0002] In the process of liquid transportation, the water pump, as one of the main mechanical equipment, can pressurize the transported liquid and transport it to the designated location. The traditional water pump sucks the liquid at the water inlet into the pump through the impeller to pressurize it, and transports it through the water outlet. Going out, since the water inlet and the water inlet are both fixed models and cannot be adjusted, the amount of water delivered is also fixed and cannot be adjusted. It is difficult to control when the delivery volume is small. High-quality water pumps are used for liquid transportation, which is easy to cause additional costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flow-controllable water pump, which can adjust the outp...
