The invention belongs to the technical field of water pumps, and particularly relates to an automatic pressure regulating water injection pump. The pump comprises a pump body, a water storage cavity and a rotating unit; a motor is located on the left side of the water storage cavity; a water inlet is formed in the left side of the water storage cavity; a water outlet is formed in the upper surface of the water storage cavity; the bottom of the outer surface of the water outlet is fixedly connected with a first gas collecting cavity; and when the pressure intensity of a water source in the water storage cavity is increased, water in the water storage cavity can timely burst through a barrier plate, so that the barrier plate moves towards the peripheral side of the water outlet, the pressure of the water source in the water storage cavity is reduced by enlarging the diameter of the water outlet, the load of the motor is synchronously reduced, meanwhile the water outlet efficiency of the water pump can be improved, cutting edges on the surfaces of blades can effectively smash garbage in the water storage cavity, then the garbage flows out along the water outlet, through the design that a heat dissipation cavity communicates with the water storage cavity, the water source in the water storage cavity enters the heat dissipation cavity, and the temperature of the motor is reduced through the water source in the heat dissipation cavity.
Description
technical field [0001] The invention belongs to the technical field of water injection pumps, in particular to an automatic pressure-regulating water injection pump. Background technique [0002] The water injection pump is a machine that transports liquid or pressurizes the 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, suspension, etc. Emulsion and liquid metal, etc., can also transport liquid, gas mixture and liquid containing suspended solids. The technical parameters of water injection pump performance include flow rate, suction lift, head, shaft power, water power, efficiency, etc., according to different working principles. Divided into volumetric water injection pumps, vane pumps and other types, volumetric pumps use the change in the volume of their working chambers to transfer energy, and...
