Problems solved by technology

For the environment with large water demand, in order to keep the pressure in the water pipe stable, it is often necessary to use a larger pressure tank, which makes the entire deep well pump system consume more energy and is prone to pressure instability.
Moreover, the overall working efficiency of the motor of the existing deep well pump is still at a low level, and the working status is difficult to monitor; the pump body of the deep well pump system also often suffers from wear and tear of the impeller, which is not easy to maintain

Abstract

The invention discloses a constant-pressure deep-well pump system and a control system and method thereof. The control system comprises a control module, an AD data sampling module, a communication output module, a water shortage and overload detection module and an undervoltage detection module. The AD data sampling module is used for receiving a pressure value in a water supply pipeline and is connected with the MCU control chip, and the MCU control chip controls and quickly starts the motor by receiving information of the pressure value in the water supply pipeline when the pressure value received by the AD data sampling module is lower than a set pressure value; and when the pressure value detected by the AD data sampling module reaches or is higher than a set value, the MCU control chip controls the motor to slowly reduce the speed until the constant pressure in the water supply pipeline is kept unchanged, and the motor stops working. According to the constant-pressure deep-well pump system, the use efficiency of the motor is greatly improved, the use size and frequency of an external pressure tank connected with the system can be reduced, and the use energy consumption of the whole system is reduced.

Description

technical field [0001] The invention relates to the technical field of deep well pumps, in particular to a constant pressure deep well pump system and a control system and control method thereof. Background technique [0002] The deep well pump is a pump used to pump or transport groundwater to the surface, which is widely used in farmland irrigation and drainage, industrial and mining enterprise drainage and other fields. [0003] At present, in order to improve the pumping efficiency and prevent the motor from starting repeatedly, most of the pressure tanks need to be connected to the water supply pipeline. For environments with high water consumption, in order to maintain the pressure in the water pipes stable, it is often necessary to use a large pressure tank, which makes the energy consumption of the entire deep well pump system larger, and is prone to pressure instability. In addition, the overall working efficiency of the motor of the existing deep well pump is stil...
