Optimal delay control system for auxiliary pumps for secondary water supply

Abstract

The invention discloses an optimal delay control system for auxiliary pumps for secondary water supply. The optimal delay control system comprises a water inlet pipe fitting, a pressure measurement gauge, a flow detection device, a valve, a water storage surge tank, a main water supply pump, auxiliary water supply pumps, induction controllers, a water outlet pipeline component, a water quality monitoring device and a control system device. The water inlet pipe fitting is mounted on the water storage surge tank, the pressure measurement gauge and the valve are mounted on the water inlet pipe fitting, the main water supply pump and the auxiliary water supply pumps are connected with the water storage surge tank, the induction controllers are mounted on the water pumps, and the water outlet pipe component is connected with the water outlet ends of the main water supply pump and the auxiliary water supply pumps. The optimal delay control system is characterized in that the auxiliary pump inlet time period, delay switching time, number of auxiliary pumps, auxiliary pump inlet / auxiliary pump outlet frequency, and auxiliary pump inlet / auxiliary pump outlet delay are set in a control system of the control system device. By the optimal delay control system, the problems that the control of start and stop of the auxiliary pumps for secondary water supply based on the frequency change ofa frequency converter during high-peak and off-peak hours cannot achieve energy conservation and consumption reduction but results in instable system operation are solved.

Description

technical field [0001] The invention relates to the field of an auxiliary pump control system in a secondary water supply device, in particular to an optimized time-delay control system for a secondary water supply auxiliary pump. Background technique [0002] In recent years, with the rapid development of my country's urban construction, the number of high-rise buildings in large and medium-sized cities in China has continued to increase. As we all know, the water supply of urban high-rise buildings requires the use of secondary water supply equipment, so the market demand for secondary water supply equipment has increased rapidly in recent years. However, when ordinary secondary water supply equipment is in use, an auxiliary pump is usually installed. When the secondary water supply system is running with a small load, the frequency converter in the secondary water supply equipment judges the frequency conversion frequency and water supply pressure to determine whether it ...

AI Technical Summary

Problems solved by technology

In actual use, due to the high water supply system of urban high-rise buildings, there are peak water consumption periods and low peak water consumption periods, so that ordinary secondary water supply equipment uses frequency converters to determine whether to start the auxiliary pump operation, and the secondary water supply equipment cannot be guaranteed. At the same time, when the secondary water supply equipment system starts the operation of the auxiliary pump, the overall equipment system is not stable, and the switching between the main pump and the auxiliary pump is not accurate, resulting in a large amount of air often entering the main pump or the auxiliary pump during the switching process, which greatly Reduced overall life of main and auxiliary pumps, while also producing a lot of noise
