The technical solution of the utility model is:
A kind of integrated form intelligent water supply pumping plant, comprise water tank, cistern water supply pump group, current stabilization jar, laminate supply-water pump group and intelligent controller, integrated form intelligent water supply pumping plant water source inserts from municipal network water supply, by being divided into two water inlet branch roads behind the strainer, wherein a water inlet branch road is communicated with by the water inlet of motor operated valve with described current stabilization jar, the delivery port of described current stabilization jar is communicated with the described water inlet that laminates the supply-water pump group, the described delivery port that laminates the supply-water pump group with go out water conduit tube and be communicated with; Another water inlet branch road is communicated with the water inlet of described water tank by motor operated valve, and the delivery port of described water tank is communicated with the water inlet of described cistern water supply pump group, and the delivery port of described cistern water supply pump group goes out water conduit tube and is communicated with described; The liquid level sensor that is provided with in the described water tank, described current stabilization jar with describedly go out the pressure sensor that is provided with on the water conduit tube, describedly laminate water supply pump, described cistern water supply water pump all is connected with described intelligent controller.
Describedly go out on the water conduit tube to be connected with air pressure tank.
Described current stabilization jar upper end is provided with vacuum suppresser, and its lower end is provided with the cleaning blowoff valve.
Described water tank is a stainless steel water tank.
The beneficial effects of the utility model are:
1, the utility model is provided with two cover water pump assemblies, and two cover water pump assemblies are standby each other, and when the municipal water sources water supply capacity was sufficient, startup laminated the water supply pump unit, makes full use of municipal ductwork pressure, reaches energy-conservation purpose; When the city planting ductwork water supply capacity is not enough, enable the cistern water supply water pump assembly, guarantee user's water demand within a certain period of time; Simultaneously also by setting water tank water storage circulation timei, overtime enabling.This product is an integrated form equipment, combine the advantage of traditional water tank supply equipment and pipe network Pressure-superposed water supply equipment, possess characteristics such as noise is low, energy-saving effect is obvious, intelligent degree height, compact conformation, convenient management, good looking appearance, compare with the conventional press mode, owing to utilized the upstream ductwork pressure and, increased energy-saving effect in conjunction with variable-frequency control technique; Compare with pipe network Pressure-superposed water supply equipment, increased water-storing tank, improved duty water.
2, reasonable in design, the compact conformation of the utility model, and applied widely, be applicable to that city public water supply ductwork pressure can not satisfy the supercharging of the productive life water of the area of customer requirements, various multilayer, the supercharging of tall building life water, all kinds of industrial and mining enterprises.Has good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 is the structure principle chart of integrated form intelligent water supply pumping plant.
Five, the specific embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-municipal network water supply, 2-strainer, the 3-motor operated valve, 4-float valve, 5-water tank, 6-liquid level sensor, the 7-intelligent controller, 8-user, 9-butterfly valve, 10-pressure sensor, 11-goes out water conduit tube, 12-cistern water supply pump group, 13-flap valve, 14-flexible connecting member, 15-laminates the supply-water pump group, the 16-air pressure tank, and 17-cleans blowoff valve, 18-current stabilization jar, 19-vacuum suppresser, 20-electro connecting pressure gauge.
Municipal network water supply 1 is divided into two water inlet branch roads after by strainer 2, wherein a water inlet branch road is communicated with the water inlet of current stabilization jar 18 by motor operated valve 3, the delivery port of current stabilization jar 18 is communicated with the water inlet that laminates supply-water pump group 15, the delivery port that laminates supply-water pump group 15 by flap valve 13, flexible connecting member 14 and butterfly valve 9 with go out water conduit tube 11 and be communicated with; Another water inlet branch road is communicated with the water inlet of water tank 5 by motor operated valve 3, the delivery port of water tank 5 is communicated with the water inlet of cistern water supply pump group 12, the delivery port of cistern water supply pump group 12 by flap valve 13, flexible connecting member 14 and butterfly valve 9 with go out water conduit tube 11 and be communicated with; The electro connecting pressure gauge 20 that is provided with on the liquid level sensors 6 that are provided with in the water tank 4, the current stabilization jar 18 with go out water conduit tube 11 on be provided with pressure sensor 10, laminate supply-water pump group 15, cistern water supply pump group 12 all is connected with intelligent controller 7.
