Description

Technical Field

[0002] A constant-pressure variable-frequency water supply device is a water pump system used in households or commercial buildings. It combines constant-pressure control technology and variable-frequency speed regulation technology. Its basic principle is to dynamically adjust the speed of the water pump according to user needs to keep the output water pressure stable and unchanged, regardless of the change in water supply flow. The sleep function can make the water pump automatically enter a low-power consumption or completely stop running state when not in use for a long time. This can significantly reduce energy consumption, especially at night or when not in use for a long time, avoiding the waste of electric energy caused by the water pump running idly for a long time. By reducing the ineffective running time, the service life of the water pump can be effectively extended and the operation cost can be reduced.

[0036] Then, the water tank is connected through the connection ring 5 and the mounting hole 6, and then the water is conveyed through the variable-frequency water pump 7 and the first connecting pipe 4. At the same time, the pressure compensator 12 applies pressure to the inside of the conveying pipe 9, and then the variable-frequency box 23 is adjusted in cooperation with the pressure gauge 20, and the variable-frequency water pump 7 is adjusted to sleep. Then, the pipeline is connected through the conveying pipe 9, and then the valve at the top of the conveying pipe 9 is opened for switching;

[0037] The arc-shaped plate 24 at the bottom of the conveying pipe 9 is connected through the first mounting block 25 and the limiting block 26. The inner threaded cylinder 27 slides outside the limiting block 26 and rotates. Then, the inner threaded cylinder 27 is rotated to the left so that the outer threaded cylinder 28 and the inner threaded cylinder 27 are aligned. Then, the inner threaded cylinder 27 is rotated so that the inner threaded cylinder 27 and the outer threaded cylinder 28 are connected. Then, after the outer threaded cylinder 28 and the inner threaded cylinder 27 are connected, the conveying pipe 9 is limited and supported.
