Abstract

The invention discloses a total head limit pump capable of automatically regulating flow rate, and belongs to the technical field of total head immersible pumps. The total head limit pump capable of automatically regulating the flow rate comprises a diversion shell provided with a water inlet and a water outlet, an impeller located in the diversion shell, a water outlet tube and a low head water inlet tube; the water inlet of the diversion shell is the first water inlet, the water outlet of the diversion shell is connected with the water outlet tube which is provided with a high pressure spray nozzle, one end of the low heat water inlet tube is a second water inlet, the other end of the low head water inlet tube is connected to a tube body of the water outlet pipe, and an automatic water inlet valve is arranged on the low head water inlet tube. According to the total head limit pump capable of automatically regulating the flow rate, under the special circumstances of low head and large flow rate, it can be guaranteed that the total head limit pump works stably and safely and a current is within the range of a rated current, the total head limit pump can be efficiently and reliably used under the working conditions of high head and the set flow rate, the head limit and the flow rate of the total head limit pump both surpass limits which an existing water pump can reach, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of full-lift submersible pumps, in particular to a full-lift limit pump capable of automatically adjusting flow. Background technique [0002] Because submersible pumps have the law that the pump shaft power increases with the decrease of the head, the current high-lift submersible pump cannot be used as a low-lift, and can only be operated safely under high-lift conditions. If it is used under low-lift conditions, the work The current will be doubled, the motor will heat up quickly, and the power will be overloaded and the motor will be burned out, while the low-lift submersible pump cannot reach the applicable range of high-lift. At present, many submersible pumps are used in both high-lift and low-lift conditions, which will cause accidents of motor burnout due to power overload; or it can be realized by matching high-power motors, but this will greatly increase cost, wasted energy.
