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 enabling a water supply system to operate stably. The device comprises a shell with a pressure cavity, a water inlet connector and a water outlet connector, wherein the water inlet connector and the water outlet connector are coaxially arranged on two sides of the shell, the water inlet connector and the water outlet connector are in communication with the pressure cavity, and an induction support is arranged in the pressure cavity; the induction support comprises a pressure-bearing section slidably matched in the water inlet connector, a flange plate expanding outwards in the radial direction is arranged on the outer circumferential face of the end, close to the water outlet connector, of the pressure-bearing section, a return compressedspring abutting against the pressure-bearing section is arranged on the side, close to the water outlet connector, of the pressure cavity, and therefore the flange plate abuts against and blocks an inner port of the water inlet connector; and a control cavity separated from the pressure cavity is further arranged on the outer side of the shell, a magnet is embedded in the flange plate, a controlcircuit board is arranged at the part, close to the pressure cavity, of the bottom of the control cavity, and the control circuit board comprises a Hall element corresponding to the magnet. Accordingto the device, the control precision of a water pump can be improved, the structure of the control device is simplified, and matching between the water supply end and the demand end in the water supply system is facilitated.
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. ...
