Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, the utility model provides a kind of energy-efficient supply equipment, and it mainly comprises the auxiliary pump 400 of two-chamber compound steady-flow tank 100, booster pump unit 200, ejector 300 and supercharging.
Two-chamber compound steady-flow tank 100, it can be used as the intermediate water tank of this supply equipment, can respectively as the water source of booster pump unit 200 and the auxiliary pump 400 of supercharging;
Two-chamber compound steady-flow tank 100 is composited by buffering air pressure tank 110 and multi-functional air pressure tank 120;
Buffering air pressure tank 110 is serially connected on running water pipe, and it can storage of water, has the compressed air of a constant volume therein, can be used for two-way absorption and slow down various abrupt transients compression shock, be i.e. superpressure preventing booster, and anti-negative pressure is destroyed again;
Buffering air pressure tank 110 is also provided with liquid level detection device 111, is convenient to like this monitor the water yield in buffering air pressure tank 110;
Multi-functional air pressure tank 120, it is a tank body, water source can be stored, it is communicated with buffering air pressure tank 110 by the second electromagnetic valve 121, multi-functional air pressure tank 120 is buffering air pressure tank 110 tonifying Qi by the second electromagnetic valve 121, second electromagnetic valve 121 is provided with Stress control instrument 122, for detecting air pressure.
Booster pump unit 200, is connected with outlet pipeline 510 and inlet pipeline 520 in the above, and it is connected with multi-functional air pressure tank 120, and it is used to the moisturizing of multi-functional air pressure tank 120 and outside water supply;
Booster pump unit 200 specifically has several supercharging main pumps 210 to be formed in parallel successively.
The auxiliary pump 400 of supercharging, it is connected with multi-functional air pressure tank 120 and outlet pipeline 510 respectively.
Ejector 300, it is connected with inlet pipeline 520 by the first electromagnetic valve 310.
Cooperatively interacting by the said equipment, can form zero micro-water system, large discharge water system and low discharge water system.
Zero micro-water system is specifically formed as follows:
Shut down to this equipment operating pressure upper limit for the moisturizing of multi-functional air pressure tank 120 through flap valve 220 by booster pump unit 200, multi-functional air pressure tank 120 at this moment can be used as the outlet stable-pressure device of this equipment, and its function shuts down pressurize.
Large discharge water system is specifically formed as follows:
Booster pump unit 200 is directly by pressure constant pressure water supply needed for user, municipal ductwork pressure is caused to decline too much for preventing excessively suction, start the auxiliary pump of supercharging 400 with multi-functional air pressure tank 120 for water source, certain compensating flowrate is provided, pump 400 as auxiliary in supercharging compensates 20% flow, can by maximum aspiration flow restriction to 80% of design water supply flow, multi-functional air pressure tank 120 at this moment can be used as the compensating device of this equipment, and its function is compensation of regulating and storing.
Low discharge water system is specifically formed as follows:
Booster pump unit 200 and the auxiliary pump 400 of supercharging adopt 2 grades of pressure operation patterns, at this moment multi-functional air pressure tank 120 can regard an intermediate water tank as, there is retaining accumulation of energy, can realize energy-saving run, under this 2 grades of pressure operation patterns, booster pump unit 200 can do prime supercharging, it can give the moisturizing of multi-functional air pressure tank 120, mend and enough namely stop intermittent operation, do not limit by user's low discharge, therefore can run in the efficient district of booster pump unit 200;
