Abstract
A kind of frequency conversion pressurized-type water supply unit, comprise a variable frequency pump and a water main, the output of variable frequency pump is connected with water main, the control end of variable frequency pump is connected with controller, a pressure sensor or flow transmitter is provided with in water main, water main is connected with at least one auxiliary water delivery side of pump by pipeline, the control end of any one auxiliary water pump is all connected with controller each via control line, the input of any one auxiliary water pump is all communicated with the input of variable frequency pump each via pipeline, water main is connected with an air pressure tank.During water use peak, variable frequency pump full power operation, provides enough pressure in water main.Using water low-valley interval, pressure sensor in water main detects that enough pressure or flow transmitter detect tiny flow quantity, controller stops variable frequency pump running, and is maintained the normal pressure in water main by lower-powered auxiliary water pump or air pressure tank.The utility model can energy conservation.
Description
Technical field:
The utility model relates to fluid transport field, particularly relates to water-supply technology, particularly a kind of frequency conversion pressurized-type water supply unit.
Background technology:
The water supply of residential building is provided by the water tank being arranged on residential building roof usually.Water in water tank is from the feed pipe with water works.The water capacity in water tank is easily contaminated, and the pressure in the feed pipe of water works is lost after arriving water tank, wastes the energy of conveying current.In order to overcome the problems referred to above, in prior art, part residential building adopts water pump to supply water.A current stabilization surge tank is set between the arrival end and water works feed pipe of water pump, in current stabilization surge tank, keeps suitable pressure, prevent the negative pressure produced during pump working from affecting the water supply of periphery water works feed pipe.The port of export of water pump is connected to the water main of residential building, when pressure reduces in residential building water main, starts water pump.With water, usually there is period concentrated feature due to residential building, such as, when resident family's working on daytime and nighttime sleep, less with water, and resident family come home from work after and before nighttime sleep, water supply volume is comparatively large and concentrated.Therefore, high powered water pump frequent start-stop when less with water, can waste mass energy.
Summary of the invention:
The purpose of this utility model is to provide a kind of frequency conversion pressurized-type water supply unit, and described this frequency conversion pressurized-type water supply unit will solve high powered water pump in prior art and waste the technical problem of mass energy at the less period frequent start-stop of residential building water.
This frequency conversion pressurized-type water supply unit 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, a pressure sensor or flow transmitter is provided with in water main, described pressure sensor or flow transmitter are connected with described controller by holding wire, wherein, described 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.
Further, the current stabilization surge tank that the input of variable frequency pump to be connected water works feed pipe by pipeline with connects.
Further, an auxiliary pressure sensor or 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, pressure sensor in water main detects that enough pressure or flow transmitter detect tiny flow quantity, controller stops variable frequency pump running, and is maintained the normal pressure in water main by lower-powered auxiliary water pump or air pressure tank.
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, can use water low-valley interval, stops variable frequency pump running, changes by lower-powered auxiliary water pump or air pressure tank to maintain the normal pressure in water main, thus energy conservation.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of frequency conversion pressurized-type water supply unit of the present utility model.
Detailed description of the invention:
Embodiment 1:
As shown in Figure 1, frequency conversion pressurized-type water supply unit 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, a pressure sensor or flow transmitter (not shown) is provided with in water main 2, described pressure sensor or flow transmitter are connected with described controller 3 by holding wire, wherein, described 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.
Further, the current stabilization surge tank 6 that the input of variable frequency pump 1 to be connected water works feed pipe 7 by pipeline with connects.
Further, an auxiliary pressure sensor or auxiliary flow sensor (not shown) is provided with in the input of variable frequency pump 1.
The operating principle of the present embodiment is: during water use peak, variable frequency pump 1 full power operation, in water main 2, provide enough pressure.Using water low-valley interval, pressure sensor in water main 2 detects that enough pressure or flow transmitter detect tiny flow quantity, controller 3 stops variable frequency pump 1 to run, and is maintained the normal pressure in water main 2 by lower-powered auxiliary water pump 4 or air pressure tank 5.
