Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention.

As shown in figures 1 to 5 of the drawings,

the utility model provides a multi-functional intelligent constant voltage variable frequency water pump controller, which comprises a housin, the control circuit board 2 of setting in the casing, a pressure sensing subassembly for detecting water supply pressure, a heat abstractor for the controller is radiating, a set screw 5 for fixed control ware, water pump 8, control circuit board 2 includes rectifier circuit, inverter circuit, MCU control circuit 7, acquisition circuit, communication circuit, WIFI module 6, the casing includes shell 1, lower shell 4, cover framework open-ended control panel 11, pressure sensing subassembly is water pressure sensor 9, the profit probe, float switch, thermal switch and PT100, heat abstractor is 4.8 mm's aluminium system fin 3 of interval, when the controller installation is fixed to water pump 8's surface, on the one hand can make the controller reliably pinpoint on water pump 8, on the other hand, make heat accessible radiator outwards disperse. Especially the water pump is at the during operation, its inside rivers can make water pump 8 keep lower temperature, and heat abstractor then accessible fin gives water pump 8 shell with heat transfer, and then show ground promotion heat abstractor's radiating rate and efficiency, especially the inside rivers temperature of water pump can be less than ambient temperature usually, consequently when ambient temperature is higher, can form great difference in temperature between water pump shell and the heat abstractor, and then be favorable to making heat abstractor keep at lower temperature, in order to ensure intelligent water pump controller's long-time steady operation, be connected with water pipe 10 on water pump 8, water pressure sensor 9 installs on water pipe 10.

As the further optimization, one side below the lower shell 4 is provided with a groove 12, the lower part of the lower shell 4 is provided with two bases 13 for connecting the water pump 8, the upper shell 1 is made of PLA material through 3D printing technology, which is different from the traditional plastic material, the shell is more convenient to replace and maintain, can be replaced in time when damaged, and has relatively lower manufacturing cost, the control panel 11 is provided with a constant pressure control key, a timing key and a water shortage protection key, the constant pressure control key can enable the water pump 8 to work in a constant pressure state, so that the water pump 8 always works under a certain pressure, and when the water demand is reduced, the rotating speed and the power of the water pump 8 are reduced; when the water demand increases, the rotation speed and power of the water pump 8 are increased, so that different demands of the water end are met, and the water pressure of the water supply pipeline is ensured to be maintained in a relatively constant state. Timing button then can carry out automatic timing switch machine according to the user's demand to can switch into manual mode, the protection button that lacks water does not have water when detecting the inlet tube, auto-stop, and send out the lack of water through WIFI module 6 and warn user APP, the present water pump of suggestion user lacks water, once every 2 hours automatic start after shutting down, judge once more whether come water. And when water comes, the running state is automatically recovered.

The implementation principle of the multifunctional intelligent constant-voltage variable-frequency water pump controller of the embodiment is as follows: link together water pump controller and water pump 8, start water pump controller, with the water pressure data that water pressure sensor 9 acquireed and water pump 8's inductance data transfer feed water pump controller, feed back to the user through the controller to through WIFI module 6 with information feedback to user APP, realize control through remote operation. And compares the water pump output pressure value set by the user with the actual water pressure value collected by the water pressure sensor 9. When the set pressure value is larger than the actual water pressure, the water pump controller controls the water pump motor to rotate in an accelerating mode, the water outlet pressure is increased, and the set pressure value is reached. When the set pressure value is smaller than the actual water pressure, the intelligent water pump controller controls the water pump motor to decelerate, and the yielding water pressure is reduced, so that the set pressure value is reached. The actual water pressure is because when the user uses water, the water pressure discharged by each water tap is constant and is not influenced by other water pipes, and the output water pressure is always kept at a fixed value.
