To the pipeline between the barrier diaphragm-type pressurized water tank, be connected with gate at described total pipeline, upwards be connected with a gate through threeway at this valve and to the pipe between the barrier diaphragm-type pressurized water tank.
First booster pump and second booster pump can switch each other, and booster pump of a booster pump operation is subsequent use.The import that booster pump is directly advanced in the water outlet of many mouthfuls of well saliva wells is established hydraulic pressure sensor on total pipeline, according to the pressure of total pipeline, adjust the booster pump running frequency automatically through frequency converter.On total pipeline, be provided with barrier diaphragm-type pressurized water tank in addition; When guaranteeing that the gang of wells flow takes place to change by a relatively large margin; Booster pump has the abundant operating mode adjustment time; Avoid causing suction water pipe pressure to descend rapidly, find time or the superpressure phenomenon, and can realize the online switching of booster pump process pump and stand by pump because of the booster pump frequency conversion lags behind.
For guaranteeing that system operates steadily, on total pipeline, the combined type air inlet and exhaust valve is set, the second combined type air inlet and exhaust valve is set on the water outlet pipeline, air-breathing when trace exhaust and emptying when high speed exhaust when satisfying the pipeline water-filling, operation.On total pipeline, safety relief valve is set, prevents the pipeline superpressure.
The beneficial effect of the utility model: the airtight laminating water service system of gang of wells, adopt the airtight method that laminates to realize the second pressure water supply of gang of wells.Can make full use of the pressure energy that upper reaches gang of wells comes water.Overcome gang of wells and come the pressure of water not have utilization, the deficiency of waste electric energy.

Fig. 1 is the airtight laminating water service system schematic flow sheet of the utility model gang of wells.
Among the figure, 1-well, 2-valve, 3-pressure meter; The 4-piping filter, 5-barrier diaphragm-type pressurized water tank, 6-hydraulic pressure sensor, the 7-first combined type air inlet and exhaust valve; 8-first booster pump, 9-first control valve for water pump, 10-second booster pump, 11-second control valve for water pump; The 12-second combined type air inlet and exhaust valve, 13-frequency converter, 14-safety relief valve.
The specific embodiment
Embodiment 1: the airtight laminating water service system structure of the utility model gang of wells is done further explain.
Consult Fig. 1.The airtight laminating water service system of gang of wells mainly is made up of well 1, barrier diaphragm-type pressurized water tank 5, hydraulic pressure sensor 6, combined type air inlet and exhaust valve, first booster pump 8, first control valve for water pump 9, second booster pump 10, second control valve for water pump 11 and frequency converter 13.
Seven mouthfuls of well saliva wells 1, every mouthful of well saliva well is provided with a suction pump, and seven delivery side of pump that draw water are pooled on the total pipeline through pipeline.On total pipeline, be connected with a valve 2 and a piping filter 4 in turn, on the total pipeline between valve 2 and the piping filter 4, be connected with a pressure meter 3 through threeway.
On the total pipeline of piping filter 4 ports of export, be connected with a safety relief valve 14, barrier diaphragm-type pressurized water tank 5, a hydraulic pressure sensor 6 and first a combined type air inlet and exhaust valve 7 through threeway successively.The outlet pipe that on total pipeline, is parallel with first booster pump 8 and second booster pump, 10, the first booster pumps 8 and second booster pump 10 is aggregated on the water outlet pipeline.Be connected with first control valve for water pump 9 and the pressure meter on the outlet line of first booster pump 8, be connected with second control valve for water pump 11 and the pressure meter on the outlet line of second booster pump 10.On the water outlet pipeline that first booster pump 8 and second booster pump 10 gather, be connected with the second combined type air inlet and exhaust valve 12 through threeway.Said hydraulic pressure sensor 6 connects frequency converter 13 through holding wire, and frequency converter 13 connects first booster pump 8 and second booster pump 10 respectively through lead.To the pipeline between the barrier diaphragm-type pressurized water tank 5, be connected with gate at described total pipeline, upwards be connected with a gate through threeway at this valve and to the pipe between the barrier diaphragm-type pressurized water tank 5.
