Detection system of negative-pressure-free secondary water supply device

Abstract

The invention discloses a detection system of a negative-pressure-free secondary water supply device. The system comprises a water pressure detection device and a controller. The water pressure detection device is used for detecting water pressure data and sending the water pressure data to the controller. The water pressure data comprises influent water pressure data and exfluentwater pressure data. The controller is used for judging whether the negative-pressure-free secondary water supply device breaks down or not when the exfluent water pressure data is lower than a first preset value andthe influent water pressure data is larger than a second preset value. Therefore, whether the negative-pressure-free secondary water supply device breaks down or not is determined based on water pressure data. Compard with the manual inspection mode, the maintenance personnel can know whether the negative-pressure-free secondary water supply device breaks down or not only through checking detected water pressure data during the detection process of the negative-pressure-free secondary water supply device. Meanwhile, detected water pressure data are more reliable. Both the time and the labor force are saved. Meanwhile, the detection result of the system is more accurate and more reliable.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a detection system for non-negative pressure secondary water supply equipment. Background technique [0002] Non-negative pressure secondary water supply equipment is a device that is directly connected in series with the municipal pipe network and can take water from the municipal pipe network to supply water to users at any time. It can still provide users with water under the lowest service pressure of the municipal pipe network during peak water consumption Maximum water supply. [0003] Generally, the existing non-negative pressure secondary water supply equipment is composed of frequency conversion motor unit, non-negative pressure water tank and disinfection device, etc. The non-negative pressure secondary water supply equipment adopts manual inspection for equipment maintenance, which requires maintenance personnel Regularly go to the site to check the condit...

AI Technical Summary

Problems solved by technology

[0003] Generally, the existing non-negative pressure secondary water supply equipment is composed of frequency conversion motor unit, non-negative pressure water tank and disinfection device, etc. The non-negative pressure secondary water supply equipment adopts manual inspection for equipment maintenance, which requires maintenance personnel Regularly go to the site to check the condition of the non-negative pressure secondary water supply equipment. There is no data support for work, etc., and inspections are not in place. It can be seen that the error of manual inspection is large, and the credibility of the inspection results cannot be guaranteed.
