Water-saving performance test device of building water supply system water using apparatus

Abstract

The invention relates to a water-saving performance test device of a building water supply system water using apparatus, which belongs to the field of water supply and drainage and relates to an experimental teaching device for testing the water-saving performance of the building water supply system water using apparatus. The device comprises a pressure supply and control system, a water supply pipe network and water using apparatus test system and a data acquisition and processing system, wherein the pressure supply and control system comprises a variable-frequency water pump (2) and a frequency-modulated water pump control cabinet, supplies high pressure and low pressure needed by a pipe network and accurately controls pressure points needed by an experiment through continuously converting frequencies and regulating a manual valve (3), wherein the variable-frequency water pump (2) comprises a high-pressure variable-frequency pump and a low-pressure variable-frequency pump which concurrently work, and the frequency-modulated water pump control cabinet is used for controlling the variable-frequency water pump (2). The variation tendency and the process of data can be observed through various curves instantly drawn by water supply system testing software, and the actual operation working condition of each node water using apparatus is reflected on a picture to be more visually known and grasped by students. The device has the characteristics of less occupied land, economical property, practicability, environmental protection, no pollution, safety, reliability and stable operation.

Description

technical field [0001] The utility model relates to a water-saving performance test device for water appliances in a building water supply system, belonging to the field of water supply and drainage, and relates to an experimental teaching device for testing the water-saving performance of water appliances in a building water supply system. Background technique [0002] The water-saving performance test device for water-saving appliances in the building water supply system is an important experimental teaching device for testing the water-saving performance of some appliances in the building water supply system under different working pressures. [0003] With the increasing shortage of urban water resources, water conservation has become an important part of my country's national policy of energy conservation and emission reduction. In urban water consumption, building water accounts for 40% to 60% of urban water consumption, so it is particularly necessary to do a good job ...
