[0053] Wherein, P0 is the target output power of the motor body 1, ρ is the fluid density inside the water pump body 2, g is the acceleration of gravity, H1 is the preset lift of the water pump body 2, Q1 is the preset flow rate at the water outlet 2011 of the water pump body 22, μ is the flow coefficient, S is the cross-sectional area at the water outlet 2011 of the water pump body 22, P1 is the detection value of the pressure sensing assembly 401, and η is the preset working efficiency of the motor body 1.

[0054] Step 102: Based on the calculation result of step 101, the motor control module 1011 controls the power regulator to adjust the output power of the motor body 1 to the target output power.

[0055] The principle and beneficial effects of the above technical solution are as follows: In the present application, the power regulator can adjust the output power of the motor body 1. Specifically, after the pressure sensing assembly 401 senses the water flow pressure at the water inlet 2021, the motor control module 1011 can obtain the detection value of the pressure sensing assembly 401 in real time, and then accurately calculate the target output power of the motor body 1 based on the above formula. The motor control module 1011 can control the power regulator to adjust the output power of the motor body 1 to the target output power. Through the above scheme, the water flow through the water outlet 2011 of the water pump body 2 can always be maintained at the preset flow rate. When the water flow pressure at the water inlet 2021 decreases, the motor control module 1011 can automatically control the power regulator to increase the output power of the motor body 1, so as to ensure the water output at the water outlet 2011 and ensure the stable output of the water pump body 2. When the water flow pressure at the water inlet 2021 increases, the motor control module 1011 can automatically control the power regulator to reduce the output power of the motor body 1, so as to optimize the output power of the motor body 1 and achieve the purpose of energy saving.

[0056] An implementation method of a flow pressure self-compensating intelligent high-pressure water pump, including the following steps:

[0057] Step one: by motor driven rotating link 306 high-speed rotation, and then by rotating link 306 driven pump body inside the impeller inner disc 405 rotation, impeller inner disc 405 under the high-speed rotation of the negative pressure will flow from the water inlet 2021 into the pump body inside;

[0058] Step two: when the water flow through the water inlet 2021 into the pump body inside, will push the water inlet 2021 at the jet turbine 2022 rotation, in the jet turbine 2022 tip of the spring piston 2023 in contact with the water flow in the moment will be inward shrink, push the inside of the contact pin 2024 and pressure sensing assembly 401 contact, sensing water flow pressure, can adjust the motor speed;

[0059] Step three: the water flow in the pump body through the water disc mouth 402 into the impeller inner disc 405 inside, under the action of centrifugal force, water flow from the convection groove 4051 out into the outer ring impeller 403 area, the water flow pressure will be further increased by centrifugal, use centrifugal flow to push the outer ring impeller 403 to rotate independently;

[0060] Step four: after the water flow through the outer ring impeller 403 by the flow tank 4032 into the pump body, and then through the shunt groove 4034 back to another group of impeller inner disc 405 in, finally the water flow through the high-speed rotating guide vane 404 into the water outlet 2011.

[0061] The working principle is that the impeller disc 4 is composed of two independent impellers and disc structures inside and outside. The disc structure is connected with the motor transmission shaft 102 through the linkage shaft assembly 3. When the motor works, it can drive the disc inside to rotate at high speed, so as to suck the water flow into the inside of the pump body. The bearing is used between the outer impeller and the disc to realize the rotating operation. When the disc rotates to drive the water flow, the centrifugal force will indirectly act on the impeller, so as to drive the impeller to rotate in the same direction. In this way, the impact of the water flow on the pump body under the centrifugal force can be reduced, and the water flow impact can be used to drive the impeller, so as to reduce the power consumption of the motor. When the water flow enters the inside of the pump body through the water inlet 2021, the impact jet turbine 2022 at the water inlet 2021 is driven to rotate. The rotation of the impact jet turbine 2022 can slow down the impact of the water flow on the inner disc 405 of the impeller. Meanwhile, the rotating impact jet turbine 2022 can uniformly diffuse the water flow entering the inside of the pump body. The spring piston 2023 at the tip of the impact jet turbine 2022 will shrink inward at the moment of contacting the water flow, so as to drive the internal contact pin 2024 to contact the pressure sensing assembly 401. After sensing the water flow pressure, the motor speed can be adjusted. In the case of strong water flow, the output power of the motor can be appropriately reduced to achieve the purpose of energy saving. The water flow in the inside of the pump body enters the inside of the inner disc 405 of the impeller through the water disc port 402. Under the action of the centrifugal force, the water flow flows out from the counterflow groove 4051 into the outer ring impeller 403 area. The pressure of the water flow thrown out by the centrifugal force will be further increased. The centrifugal water flow is used to drive the outer ring impeller 403 to rotate independently. In this way, the impact force of the water flow output from the inner disc 405 of the impeller can be consumed, so as to avoid the damage of the internal parts of the pump body caused by long-time water flow impact. Meanwhile, the rotating outer ring impeller 403 will also generate centrifugal force on the water flow, so as to compensate part of the pressure consumed by the water flow, so as to ensure the normal flow rate of the water flow in the inside of the pump body. The water flow after the outer ring impeller 403 enters the pump body through the diffuser groove 4032, and then flows back to another set of inner disc 405 through the flow distribution groove 4034. Finally, the water flow enters the water outlet 2011 through the high-speed rotating guide vane 404.
