Intelligent pipe network pressure-superposed non-negative pressure variable frequency water supply device

Abstract

The invention discloses an intelligent pipe network pressure-superposed non-negative pressure variable frequency water supply device. The intelligent pipe network pressure-superposed non-negative pressure variable frequency water supply device is mainly composed of a flow stabilization compensator, a negative pressure eliminator, a water shortage signal transmitter, a water level sensor, an air compensation tank, a water pump and a control cabinet; two parts including a flow stabilization cavity and a high-pressure energy storage cavity are integrated to the flow stabilization compensator; the air compensation tank is arranged on the outer side of the high-pressure energy storage cavity and is installed on the flow stabilization compensator fixedly; a connecting pipe is arranged at the bottom of the air compensation tank to be communicated with a small flow pipe; and a water inlet solenoid valve is installed on the connecting pipe. The intelligent pipe network pressure-superposed non-negative pressure variable frequency water supply device has the beneficial effects that the flow stabilization compensator is of dual-cavity integration structure including the flow stabilization cavity and the high-pressure energy storage cavity, the structure is compact, and the occupied land is small; in addition, energy saving can be achieved through the pressure of a tap water inlet pipe; normal water supplying can be guaranteed during small flow pump stopping of the high-pressure energy storage cavity, so that the pump stopping energy saving effect is achieved; meanwhile, the service life is prolonged; after the high-pressure energy storage cavity deflates, automatic air compensation can be achieved; and the intelligent pipe network pressure-superposed non-negative pressure variable frequency water supply device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to an intelligent pipe network stacking pressure-free frequency conversion water supply equipment. Background technique [0002] Because of the cancellation of pools, water tanks and other facilities, and the use of tap water inlet pressure, the pipe network stacking water supply has outstanding advantages such as energy saving, sanitation, small footprint, and convenient maintenance. Secondary water supply application. However, the pipe network stacking water supply equipment on the market cannot well solve the energy saving problem of the water pump in small flow water supply. However, the air pressure water tank has phenomena such as air leakage and air infiltration, and needs to be replenished regularly. The air pressure water tank in the prior art usually uses an air compressor or an air storage tank to supply air, which is not conducive to space-saving installa...

Problems solved by technology

However, the pipe network superimposed water supply equipment on the market can not solve the energy saving problem of the water pump in the small flow water supply. Some of them install a pneumatic water tank in the outlet pipe of the water pump, and use the energy storage function of the pneumatic water tank to realize the small flow of the pump. energy-saving water supply, but the air pressure water tank has air leakage, air seepage and other phenomena, and it needs to be replenished regularly. The air pressure water tank in the prior art usually uses an air compressor or an air storage tank to replenish air, which is not conducive to economical installation and maintenance. , and the cost is also high. Although the diaphragm type air pressure water tank can alleviate the problem of on-site air supply, the diaphragm has problems such as easy aging, flexure cracking, fatigue life, and precipitated water pollution. Moreover, the diaphragm type air pressure water tank The tank also has seal leakage, air leakage and other phenomena. If it is used for a long time without detection and pre-filled gas, it will lose the effect of energy storage and pressure water supply.
