Novel testing and evaluating system for intelligent water supply equipment

Abstract

The invention discloses a novel testing and evaluating system for intelligent water supply equipment. The system comprises a reservoir, a water inlet pipeline, a water outlet main pipe, an outlet pipe network and a control center. Water inlet pressure is maintained by using a constant-pressure pump, and municipal pipe network water supply pressure is simulated; three branches with different range flowmeters are connected behind the water outlet main pipe according to the water consumption amount, so that the measurement precision is guaranteed; valves are arranged in front of and behind the flowmeters according to the size of pipe diameters; a ball valve is arranged on the pipe with a small pipe diameter and a butterfly valve is arranged on the pipe with a big pipe diameter; pipe resistance loss and floor height are simulated by using loss due to valves at the outlet branch pipes; the pipe resistance loss before water entering buildings is simulated by the ball valves; the floor height is simulated by the reducing valves, and the pipe resistance loss after water entering buildings is simulated by another ball valves; a water source container and a water return container are combined into the reservoir, a flow baffle plate is additionally arranged in the middle of the reservoir to prevent discharge flow and incoming flow interference, and the waste of water resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of performance monitoring of a water pump group and a control system, and in particular relates to a new type of intelligent water supply equipment test and evaluation system. Background technique [0002] At present, intelligent water supply is a water supply system that is gradually promoted in modern buildings. With the development of frequency conversion speed regulation technology and the improvement of people's requirements for water quality, this mode of direct water supply is more and more widely used in residential quarters, Water supply systems such as high-rise buildings, and various intelligent water supply equipment have also emerged one after another. [0003] There are many smart water supply equipment on the market, so a test and evaluation system close to the real water supply situation is needed to test its performance. Although the existing water supply equipment test bench has simply sim...

AI Technical Summary

Problems solved by technology

Although the existing water supply equipment test bench simply simulates the water source (pool) and the inlet and outlet pipelines, it does not realize the real simulation of multi-user, randomness and fluctuation of water supply for buildings, and cannot accurately reflect the water supply performance of the water supply equipment. And its intelligent control effect requires a large water supply pressure margin to ensure that the real water supply pressure is met, resulting in low efficiency and high energy consumption of water supply equipment
