Problems solved by technology

When the motor power of the water pump is abnormal, if the motor of the water pump continues to run normally with load, it will not only consume energy, but also easily burn the motor; The reason for the rotation is caused by abnormal power. On the other hand, after the motor of the water pump stops, the capacitor in the motor still stores current, so there is a safety hazard for the maintenance personnel.

Embodiment 1

[0054] figure 1 It is a flow chart of a water pump control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the running state control of the water pump motor is required. The method can be executed by the water pump control device, wherein the device can be controlled by software and / or hardware implementation, refer to figure 1 , the water pump control method provided in this embodiment may specifically include the following steps:

[0055] S110. Obtain the water pressure at the water pump station.

[0056] Wherein, the water pressure at the pump room of the water pump can be obtained through a sensor installed at the water inlet of the pump room, and the sensor is preferably a pressure sensor. When the water level at the pump room is low, the pressure of the pump in the water is small; when the water level at the pump room is high, the pressure of the pump in the water is high. The sensor can be used to collec...

Embodiment 2

[0063] This embodiment provides a water pump control method on the basis of the above embodiments, and provides an optimal solution for controlling the running state of the motor according to the power of the motor. figure 2 It is a flowchart of a water pump control method in Embodiment 2 of the present invention, refer to figure 2 , the water pump control method provided in this embodiment may include the following:

[0064] S210. Obtain the water pressure at the pump room of the water pump.

[0065] S220. Convert the water pressure at the pump room of the water pump into the power of the water pump motor.

[0066] S230. Determine whether the power of the water pump motor is less than a preset power, if yes, perform S240, and if not, do not process.

[0067] Specifically, the preset power may be 85% of the rated power of the water pump motor. For example, if the rated power of the water pump motor is 100W, the preset power is 85W.

[0068] S240. When the power of the wate...

Embodiment 3

[0082] This embodiment provides a water pump control method based on the above embodiments, and specifically provides a processing solution when the power is high. image 3 It is a flowchart of a water pump control method in Embodiment 3 of the present invention, refer to image 3 , the water pump control method provided in this embodiment may include the following:

[0083] S310. Obtain the water pressure at the water pump station.

[0084] S320. Convert the water pressure at the water pump house into the power of the water pump motor.

[0085] S330, judging whether the power of the water pump motor is greater than the preset power upper limit, if yes, execute S340, if not, do not process.

[0086] Specifically, the power upper limit may be 120% of the rated power of the water pump motor. For example, if the rated power of the water pump motor is 100W, the power limit is 120W.

[0087] S340. When the power of the water pump motor is greater than the upper limit of power, ...

Abstract

The embodiment of the invention discloses a water pump control method, device and system. The water pump control method. The water pump control method comprises the following steps: acquiring a water pressure of a water pump house; converting the water pressure of the water pump house into power of a water pump motor; and controlling the operating state of the motor of the water pump according to the power of the water pump motor. The technical scheme of the embodiment solves the problem of high energy consumption and potential safety hazards when the power of an existing water pump motor is abnormal and provides the safe and energy-saving water pump control method.

Description

technical field [0001] Embodiments of the present invention relate to water pump control technologies, and in particular to a water pump control method, device and system. Background technique [0002] A water pump is a mechanical device primarily used to transport liquids. In daily production and life, it is often necessary to timely and accurately control the running state of the motor of the water pump. [0003] At present, when the power of the motor of the water pump is lower than the preset power or exceeds the upper limit of power, the motor of the water pump either continues to run with load, or stops running immediately. When the motor power of the water pump is abnormal, if the motor of the water pump continues to run normally with load, it will not only consume energy, but also easily burn the motor; The reason for the rotation is due to abnormal power. On the other hand, after the motor of the water pump stops, the capacitor in the motor still stores current, w...
