Abstract

The invention provides a variable-flow type water pump which comprises a pump case, a motor, a water inlet pipeline, a water outlet pipeline and a flow adjusting device. The flow adjusting device is arranged in the water outlet pipeline, so that a user can select the flow size as needed when the water pump is used; when the variable-flow type water pump is used, water flows into the pump case viathe water inlet pipeline and then, water in the water inlet pipeline is pumped into the water outlet pipeline via an impeller; when water reaches the water outlet pipeline, the flow adjusting device adjusts the water yield; in addition, a control chip is utilized to adjust the rotary speed of the impeller, so that the rotary speed of the impeller is also adjusted to be low when the flow adjustingdevice adjusts the water yield to be small; and the rotary speed of the impeller is also adjusted to be high when the flow adjusting device adjusts the water yield to be large, so that the impeller runs in a matching manner along with the water yield to realize the purpose of saving electric energy.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a variable flow water pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. However, the existing water pumps cannot realize the change of the flow rate, so the flow rate cannot be adjusted according to the usage requirements. Contents of the invention [0003] The invention provides a variable flow water pump, which is used to enable the water pump to realize the purpose of flow regulation. [0004] The invention provides a variable flow water pump, comprising: a pump casing, a motor, a water inlet pipe, a water outlet pipe, an impeller and a flow regulating device. In the pump cas...
