Automatic water pressure detecting and adjusting system

Abstract

The invention discloses an automatic water pressure detecting and adjusting system which comprises a water pump, a motor, a programmable logic controller, a pressure sensor and a frequency converter, wherein the motor is used for driving the water pump; the pressure sensor is installed on a water supply pipe and used for detecting the actual pressure of the water supply pipe, and the output end of the pressure sensor is connected with the input end of the programmable logic controller; and the frequency converter is used for controlling the motor to drive the water pump to work and the input end of the frequency converter is connected with the output end of the programmable logic controller. According to the automatic water pressure detecting and adjusting system, hardware such as the programmable logic controller, the frequency converter, a liquid level sensor and the pressure sensor is utilized to detect and adjust the water pressure of water supply equipment automatically, water supply efficiency of the equipment is improved, electric power resource waste is reduced, the normal service life of the water pump motor is prolonged, and the prominent problems of insufficient / excessive water supply and underpressure / overpressure of water pressure, likely to happen before, are solved.

Description

technical field [0001] The invention relates to the field of water supply systems, in particular to an automatic detection and adjustment water pressure system. Background technique [0002] In the water supply system, the motor is often used to drive the gear pump to deliver the water in the storage tank to the user through the pipeline. The motor speed of this working method is relatively constant. The water pressure is lower, especially for users on high floors. The water pressure is unstable. If the water pressure is too high, the water pipe will burst easily. If the water pressure is too low, it will not be able to transport water to high-rise users. Therefore, the water pressure in the existing water supply system is not constant and cannot be adjusted. [0003] If a high-power motor is used to pump water, although the water pressure will increase, the power consumption will be large, and excessive power resources will be wasted. [0004] The information disclosed in...

Problems solved by technology

The water pressure is unstable. If the water pressure is too high, the water pipe will burst easily. If the water pressure is too low, it will not be able to deliver water to the high-rise users. Therefore, the water pressure in the existing water supply system is not constant and cannot be adjusted.

[0003] If a high-power motor is used to pump water, although the water pressure will increase, the power consumption will be large, and too much power resources will be wasted.
