Abstract
The utility model relates to an adopt box no negative pressure water supply equipment of quimby pump unit, including water tank diversion device supercharging device, stationary flow jar, pump assembly, no negative pressure flow controller, variable frequency control cabinet, the water tank in be equipped with the diversion device, diversion device, supercharging device, stationary flow jar and pump assembly communicate each other, and the stationary flow jar still communicates with no negative pressure flow controller, and no negative pressure flow controller links to each other with the water supply network, pump machine bond to user pipe network, the pump assembly be the quimby pump unit.
Description
Technical field
The utility model relates to the pump assembly device in a kind of secondary water supply system, and the pump assembly device especially in box type negative-pressure-free supply equipment system, belongs to plumbing technical field.
Background technology
Box type negative-pressure-free water system is primarily of airtight water tank, priming device, supercharging device, main pump unit, frequency-conversion control cabinet, pressurizer, form without vacuum flow amount controller, steady-flow tank and pipeline.Its operating principle is that the water of tap water pipe network directly enters user entering user's front portion, and another part is entered in airtight water tank by pipeline and stores.When with water low ebb, tap water utilizes hydraulic pressure in pipe network directly to enter in user family, and when water use peak, in pipe network, hydraulic pressure is not enough, and the water now in airtight water tank enters in pipe network by water booster system supercharging, ensures the just conventional water of resident, there will not be phenomenon of cutting off the water.
Water pump assembly is as the core in box type negative-pressure-free water system, and whether normal its operation conditions is will be related to the operation of whole water system.At present, box type negative-pressure-free water system adopts centrifugal multistage pump multiple centrifugal pump as core water pump assembly.Centrifugal multistage pump multiple centrifugal pump enters irregular operation district when low flow rate condition, easily produces vibration.And centrifugal pump is due to its operating principle, pump discharge reduces greatly along with the change of lift, will bring the frequent variations of user's water supply volume.When unstable operation appears in pump assembly, vibration can cause pump assembly termination of pumping.Therefore need to adopt a kind of stable, without the new pump-type in low discharge irregular operation district as main pump unit.
Utility model content
This practicality provides a kind of box type negative-pressure-free supply equipment adopting Quimby pump unit for above-mentioned deficiency.
The utility model adopts following technical scheme:
A kind of box type negative-pressure-free supply equipment adopting Quimby pump unit described in the utility model, comprises water tank, priming device, supercharging device, steady-flow tank, pump assembly, without vacuum flow amount controller, and frequency-conversion control cabinet; Priming device is provided with in described water tank; Priming device, supercharging device, steady-flow tank and pump assembly are interconnected, and steady-flow tank also with without vacuum flow amount controller is communicated with, and are connected with water supply network without vacuum flow amount controller, and pump machine connects user's pipe network; Described pump assembly is Quimby pump unit.
The box type negative-pressure-free supply equipment of employing Quimby pump unit described in the utility model, described steady-flow tank is also provided with pressurizer.
beneficial effect
The box type negative-pressure-free supply equipment of the employing Quimby pump unit that the utility model provides is easy for installation, stable, can not produce huge vibration.More stages centrifugal pump fundamentally can solve the vibration and flow decline problem that bring because of vane pump performance fluctuation of service.The noise that Quimby pump unit produces is low, and all adopts flexible joint to be connected with pipe network connected mode, the puzzlement that noise is large.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1: a kind of box type negative-pressure-free supply equipment adopting Quimby pump unit, comprises water tank 1, priming device 2, supercharging device 3, steady-flow tank 4, Quimby pump unit 5, without vacuum flow amount controller 6, frequency-conversion control cabinet 7; Priming device 2 is provided with in described water tank 1; Priming device 2, supercharging device 3, steady-flow tank 4 and pump assembly are interconnected, and steady-flow tank 4 also with without vacuum flow amount controller 6 is communicated with, and are connected with water supply network without vacuum flow amount controller 6, and pump machine connects user's pipe network; It is characterized in that: described pump assembly is Quimby pump unit 5.Steady-flow tank 4 is also provided with pressurizer 8.
The utility model is achieved through the following technical solutions.Main pump unit adopts Quimby pump, and water feeding of water pump pipeline is connected with airtight water tank, adopts flexible joint to connect.Pump outlet is directly connected with user's water supply pipe, adopts flexible joint or other flexible joints.
After Quimby pump unit brings into operation, engaging each other and the closely cooperating of screw rod and lining inwall between each screw rod, between pump intake and outlet opening, will be separated into one or more seal cavity.Along with rotation and the engagement of screw rod, these seal cavities are constantly formed in the suction side of pump, wherein liquid-filled by suction chamber, and pass continuously to outlet side along screw axial from suction chamber, are constantly discharged by the liquid be enclosed in each space.Because the structure of Quimby pump precision constructs, pump group itself is rational in infrastructure, and pump performance there will not be unstable situation, and pump discharge is only relevant with revolution speed, and lift is stablized, avoid the various problems that the judder that occurs because of water pump assembly fluctuation of service brings.
