Abstract

The invention relates to water pump control technology, and aims to provide a sensorless constant pressure pump valve integrated device for improving energy efficiency in HVAC; the inventive device includes a water pump; The pipeline and the outlet pipeline are respectively equipped with valve body adjustment components; the information monitoring and analysis device and the two valve body adjustment components are respectively connected to the terminal through the cable, and the terminal is connected to the programmable controller and the industrial computer in turn through the cable; the device is through The corresponding flow parameters are obtained from the voltage and current signals. According to the characteristic curve of the device under this working condition and the Kv value of the device at this time, the pressure of the pipe network can be kept constant by controlling the opening of the valve, and the pressure signal obtained is more accurate. Faster and more accurate.

Description

technical field [0001] The invention relates to water pump control technology, in particular to a non-sensing constant pressure pump valve integrated device used in heating, ventilating and cooling to improve energy efficiency. Background technique [0002] Water pumps and valves are widely used in transmission and distribution systems such as air-conditioning water systems, regional hot water supply systems, and industrial circulating water systems. However, the energy consumption of traditional transmission and distribution systems is very large, and the pumps are often running continuously at full load. The degree of automation is low. As for the acquisition method of the pressure signal, the traditional method is to obtain it through the flow meter, and the pressure sensor is also involved in this process. There is a certain time delay in the process of obtaining the signal. After the pressure signal is obtained, the frequency of the water pump or fan and the valves in ...
