Summary of the invention:
The purpose of this utility model is the frequency conversion pressurized-type water supply unit providing a kind of improvement, and the frequency conversion pressurized-type water supply unit of described this improvement will solve high powered water pump in prior art is wasted the technical problem of mass energy at the less period frequent start-stop of residential building water.
The frequency conversion pressurized-type water supply unit of this improvement of the present utility model, comprise the water main of a variable frequency pump and a residential building, described variable frequency pump comprises an input, an output and a control end, the output of variable frequency pump is connected with described water main by pipeline, the control end of variable frequency pump is connected with a controller by control line, wherein, a flow transmitter is provided with in water main, described flow transmitter is connected with described controller by holding wire, water main is connected with at least one auxiliary water delivery side of pump by pipeline, the control end of the auxiliary water pump described in any one is all connected with described controller each via control line, the input of any one auxiliary water pump is all communicated with each via the input of pipeline with described variable frequency pump, water main is connected with an air pressure tank, the input of variable frequency pump to be connected water works feed pipe by pipeline current stabilization surge tank with one connects, a bypass duct is connected with between water works feed pipe and water main, an electromagnetic valve is provided with in described bypass duct, the control end of described electromagnetic valve is connected with controller by control line.
Further, an auxiliary flow sensor is provided with in the input of variable frequency pump.
Operating principle of the present utility model is: during water use peak, variable frequency pump full power operation, in water main, provide enough pressure.Using water low-valley interval, flow transmitter in water main detects tiny flow quantity, controller stops variable frequency pump running, the normal pressure in water main is maintained by lower-powered auxiliary water pump or air pressure tank, in the period of stopping water, when the flow transmitter in water main can't detect flow, close auxiliary water pump, open electromagnetic valve and connect bypass duct, utilize pressure in the feed pipe of water works to air pressure tank supplementary pressure.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model connects auxiliary water pump and air pressure tank on residential building water main, a bypass duct is connected with between water works feed pipe and water main, electromagnetic valve is provided with in bypass duct, water low-valley interval can used, variable frequency pump is stopped to run, change by lower-powered auxiliary water pump or air pressure tank to maintain the normal pressure in water main, in the period of stopping water, when flow transmitter in water main can't detect flow, close auxiliary water pump, open electromagnetic valve and connect bypass duct, utilize pressure in the feed pipe of water works to air pressure tank supplementary pressure, thus energy conservation.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of the frequency conversion pressurized-type water supply unit of improvement of the present utility model.
Detailed description of the invention:
Embodiment 1:
As shown in Figure 1, the frequency conversion pressurized-type water supply unit of improvement of the present utility model, comprise the water main 2 of a variable frequency pump 1 and a residential building, described variable frequency pump 1 comprises an input, an output and a control end, the output of variable frequency pump 1 is connected with described water main 2 by pipeline, the control end of variable frequency pump 1 is connected with a controller 3 by control line, wherein, a flow transmitter (not shown) is provided with in water main 2, described flow transmitter is connected with described controller 3 by holding wire, water main 2 is connected by the output of pipeline with at least one auxiliary water pump 4, the control end of the auxiliary water pump 4 described in any one is all connected with described controller 3 each via control line, the input of any one auxiliary water pump 4 is all communicated with each via the input of pipeline with described variable frequency pump 1, water main 2 is connected with an air pressure tank 5, the input of variable frequency pump 1 to be connected water works feed pipe 7 by pipeline current stabilization surge tank 6 with one connects, a bypass duct 8 is connected with between water works feed pipe 7 and water main 2, an electromagnetic valve 9 is provided with in described bypass duct 8, the control end of described electromagnetic valve 9 is connected with controller 3 by control line.
