Water supply control method for water pump

Abstract

The invention discloses a water supply control method for a water pump, and belongs to the technical field of water supply control. In an existing control technology, relatively more detection parts and components are required, the input cost is relatively high, a control method is complex, a control flow is unreasonable, a water supply parameter cannot be flexibly regulated, and leakage, water shortage and the like cannot be accurately identified. According to the method, different working modes are set according to different working environments, working pressure values of the pump are set according to different requirements, and the method can be applied to various water supply conditions. An information acquisition unit is only required to acquire a pressure value in the pump, so that the number of the detection parts and components can be reduced. A data processing unit is used for processing data according to a related algorithm, whether the water pump is required to be started or not and whether the conditions of leakage, pipe burst, water shortage, water overflow and the like exist or not can be accurately judged, and various conditions can be intelligently identified and processed without resetting the control method and increasing the water supply cost. According to the method, the water supply parameter can be flexibly regulated, and the control flow is simple and reasonable.

Description

technical field [0001] The invention relates to a water supply control method of a water pump, belonging to the technical field of water supply control. Background technique [0002] Nowadays, there are many high-rise buildings, and ordinary waterways cannot meet the water supply requirements. It is necessary to install water pumps in the waterway pipelines to increase the pressure of the water in order to supply water to high places. The water pump generally needs to be controlled electrically when in use. The simplest control method is to use a knife or an air switch or only a liquid level float switch to control the water level. Although this method is low in cost, it has no pump protection function and cannot Changing the working frequency of the motor makes it impossible to adjust the speed of the motor. If the motor runs at high power all the time, energy will be wasted. If the motor runs at low power, it may not be able to meet the water supply requirements. Eventuall...

AI Technical Summary

Problems solved by technology

However, the existing control technology needs to detect water flow, water pressure, water level and other data, requires more detection components, high investment cost, complicated control method, unreasonable control process, and can only be applied in a single environment , cannot be applied to multiple environments at the same time, when the water supply environment changes, the control method needs to be reset, increasing the cost of water supply

Moreover, the water supply parameters cannot be flexibly adjusted, and the motor speed cannot be flexibly adjusted, resulting in an unsteady working pressure of the pump, unstable water pressure, and inability to accurately identify leakage, water shortage, etc.
