Full-automatic pot-type pipe network differential pressure compensation energy conservation water supply plant

Abstract

The invention discloses a full-automatic pot-type pipe network differential pressure compensation energy conservation water supply plant. The full-automatic pot-type pipe network differential pressure compensation energy conservation water supply plant is mainly composed of a flow regulating valve, a flow stabilization compensation tank, a negative pressure eliminator, a first water pump, a second water pump and a control cabinet; the flow stabilization compensation tank comprises a three-cavity horizontal type structure formed by a flow stabilization cavity, a water storage cavity and a high-pressure energy storage cavity; an installation opening is formed in the top of the high-pressure energy storage cavity, a water level sensor is installed in the installation opening in a matched mode, and a breathing pipe is further connected to the installation opening; and a connecting pipe is arranged on a water distribution pipe so as to be connected with a water storage opening of the flow stabilization compensation tank. The full-automatic pot-type pipe network differential pressure compensation energy conservation water supply plant has the beneficial effects that the advantages of being compact in structure, small in occupied land, convenient to install and maintain, sanitary in water quality and the like are achieved; in addition, differential pressure compensation adjustment on the insufficient tap water inlet amount can be carried out through the water storage cavity, the adjusting volume is increased, and the water supply safety is improved; meanwhile, the high-pressure energy storage cavity can still guarantee normal water supply and achieve the energy-saving effect during small-flow pump stopping; and the high-pressure energy storage cavity can conveniently conduct automatic air compensation.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a full-automatic tank-type pipe network differential pressure compensation energy-saving water supply equipment. Background technique [0002] With more and more high-rise buildings, secondary water supply is becoming more and more common. At present, the secondary water supply for high-rise buildings on the market mainly includes four methods: high-level water tank or water tower water supply, air pressure water supply, frequency conversion water supply and direct connection and series water supply. Compared with the previous methods, direct connection and series water supply can use The pressure of the tap water inlet pipe is reduced, and it has the advantages of less land occupation, less investment, convenient management and maintenance, energy saving and sanitation, etc., so it occupies a dominant position in the secondary water supply. Its application is lim...

At present, the secondary water supply for high-rise buildings on the market mainly includes four methods: high-level water tank or water tower water supply, air pressure water supply, frequency conversion water supply and direct connection and series water supply. Compared with the previous methods, direct connection and series water supply can use The pressure of the tap water inlet pipe is reduced, and it has the advantages of less land occupation, less investment, convenient management and maintenance, energy saving and sanitation, etc., so it occupies a dominant position in the secondary water supply. Its application is limited, and the direct series connection of water supply usually configures multiple identical pumps for parallel connection of water supply, and the selection of water pumps is based on the maximum flow rate and the highest head under the most unfavorable design conditions, which will cause the pumps to seriously deviate from the high-efficiency area when operating in small flow conditions And the phenomenon of no energy saving, and the low flow condition will often appear in the secondary water supply of high-rise buildings, sometimes even for several hours, such as early morning, so the energy saving problem of direct series connection of water supply in small flow water supply can not be ignored
