Problems solved by technology

[0004] Although the dual control technology of flow switch and pressure switch can realize the automatic operation of the water pump, but because the starting pressure setting value of the pressure switch is fixed, it is impossible to automatically adjust the starting pressure with the change of the water pressure in the tap water pressurization. As a result, the pump often fails to start
[0005] In addition, the flow switch is used to control the shutdown of the water pump. Due to the complex structure of the flow switch, it is easy to scale or get stuck during use, resulting in the failure of the pump to stop. The service life of this type of automatic control pump cannot be guaranteed. cause great inconvenience
[0006] The method of using the pressure sensor alone to realize the automatic control of the water pump, because there is only one pressure signal for the monitoring signal of the water pump, the start and stop of the water pump can only be controlled by the pressure signal, the control accuracy is not enough in the actual use process, it is easy to cause the water pump to fail Normal start and stop; especially when the water inlet pressure changes, the power supply voltage fluctuates or the performance of the water pump decreases, and the operating pressure of the water pump cannot reach the preset stop pressure, the water pump cannot stop normally, causing the water pump to run for a long time and waste electric energy. possible pipe burst

Embodiment 1

[0024] Such as figure 1 A water pump is shown, whose functional modules include a pump body 02, a drive motor 01, a pressure sensor 03, a temperature sensor 04, and a controller 05, wherein the pressure sensor 03 and the temperature sensor 04 are both installed at the water outlet of the pump body 02. On the end cavity, and communicate with the controller 05; the external power supply is connected with the controller 05, and the controller 05 is connected with the driving motor 01.

[0025] combine figure 1 and figure 2 As shown, the control steps of a water pump intelligent control method include:

[0026] Step 1: Turn on the power supply and start the water pump;

[0027] The second step: the controller 05 reads the current pressure and temperature through the pressure sensor 03 and the temperature sensor 04 respectively, and records the temperature after starting as T degrees Celsius;

[0028] Step 3: Judging whether the current pressure reaches the preset shutdown pre...

Embodiment 2

[0035] Further, combine image 3 As shown, the antifreeze control steps of a water pump intelligent control method include:

[0036] Step 1: The water pump is in a stopped state, and it is judged whether the current pressure is lower than the starting pressure;

[0037] Step 2: When the current pressure is higher than the starting pressure, continue to judge whether the current temperature is lower than 2 degrees Celsius; if the current temperature is lower than 2 degrees Celsius, the controller 05 will control the water pump to start forcibly;

[0038] Step 3: When the water pump runs for 1 minute, control the water pump to stop.

[0039] When the water pump is used outdoors, if the ambient temperature is low in winter, especially in the north; the pump cavity of the water pump is easy to be cracked by freezing when the pump is stopped, so the user needs to repair the pump when the ambient temperature is low. Empty protection to prevent the pump cavity of the pump from bein...

Embodiment 3

[0041] Additionally, combined with Figure 4 As shown, another antifreeze control step of a water pump intelligent control method includes:

[0042] Step 1: The water pump is in a stopped state, and it is judged whether the current pressure is lower than the starting pressure;

[0043] Step 2: When the current pressure is higher than the starting pressure, continue to judge whether the current temperature is lower than 5 degrees Celsius; if the current temperature is lower than 5 degrees Celsius, the controller 05 will control the water pump to start forcibly;

[0044] Step 3: Continuously judge whether the current temperature reaches 10 degrees Celsius, and control the water pump to stop if the current temperature reaches 10 degrees Celsius.

[0045] The difference between this embodiment and the above-mentioned embodiment 2 is that, when the temperature in the pump chamber detected by the temperature sensor is lower than the preset start-up temperature, the controller control...

Abstract

The invention provides a water pump intelligent control method. A pressure sensor and a temperature sensor are arranged in a cavity at the outlet end of a water pump. A controller controls the water pump to stop by presetting stop pressure of the water pump. When operation pressure of the water pump cannot reach the preset stop pressure, the controller controls the water pump to stop through temperature change of the temperature sensor, and stop pressure of the water pump is preset again.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to the technical field of automatic control of civil water pumps, and in particular to an intelligent control method for water pumps. Background technique [0002] With the improvement of people's living standards and automation requirements, the demand for civil water pumps, especially the improvement of automatic control technology for household water pumps, is becoming stronger and stronger. [0003] At present, civil water pumps mainly rely on the dual control technology of flow switch and pressure switch to realize automatic control, and some use pressure sensors alone to realize automatic control. [0004] Although the dual control technology of flow switch and pressure switch can realize the automatic operation of the water pump, but because the starting pressure setting value of the pressure switch is fixed, it is impossible to automatically adjust the starting pressure ...
