Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as figure 1 As shown, a control device that can make the water supply system run smoothly. The water supply system includes a water supply pipeline 5 and a water pump 6 for supplying water to the water supply pipeline. It has a frequency converter, so that the frequency conversion control of the water pump can be realized. In addition, one end of the water supply pipeline is connected to the downstream 52 of the user, and the other end is connected to the upstream 51 of the output end of the water pump. Such as figure 2 , image 3 As shown, the control device includes a controller, and the controller includes a housing 1, a water inlet port 12 and a water outlet port 13 coaxially arranged on the front and rear sides of the housing, and the inside of the housing is a cylindrical pressure chamber 11, and The axis of the pressure ...

The invention discloses a control device capable of running a water supply system stably, which comprises a casing with a pressure chamber, and water inlet and outlet interfaces coaxially arranged on both sides of the casing, and the water inlet and outlet are connected to each other. The pressure chamber is provided with an induction bracket in the pressure chamber, and the induction bracket includes a pressure-bearing section that is slidably fitted in the water inlet interface, and a radially outwardly expanded section is provided on the outer peripheral surface of the end of the pressure-bearing section near the water outlet interface. The flange plate is provided with a return pressure spring against the pressure-bearing section on the side of the pressure chamber close to the water outlet interface, so that the flange plate can be pressed against and block the inner port of the water inlet interface. There is a control chamber separated from the pressure chamber, a magnet is embedded on the flange, a control circuit board is arranged at the bottom of the control chamber near the pressure chamber, and the control circuit board includes a Hall element corresponding to the magnet. The invention can improve the control precision of the water pump, simplify the structure of the control device, and facilitate the matching between the water supply end and the demand end in the water supply system.
Description
technical field [0001] The invention relates to the technical field of water pump control, in particular to a control device which uses a water pump to supply water and can make the water supply system run smoothly. Background technique [0002] In the existing water pump water supply system, in order to realize the normal operation and automatic control of the water pump, it is necessary to configure a control device connected to the water supply pipeline to control the running state of the water pump, so that the water can be started to work when the water is needed downstream to supply water. , When the water is stopped in the downstream, the water pump is turned off to stop the water supply, so as to avoid excessive water pressure in the pipeline and excessive load of the water pump, resulting in waste or even damage. The control device usually includes a housing, which is provided with a water inlet and a water outlet that can be connected to the water supply pipeline. ...
