Abstract
The utility model discloses a constant pressure water supply device control system with variable frequency auxiliary pumps. The constant pressure water supply device control system with the variable frequency auxiliary pumps is characterized by comprising a controller, two variable frequency pumps, a plurality of power frequency pumps and a far transmission pressure gauge. The far transmission pressure gauge is arranged at a water outlet end of a device, and can be used for collecting discharging water pressure. The far transmission pressure gauge is connected with the controller in communication mode. The controller controls work conditions of the two variable frequency pumps and the plurality power frequency pumps according to data collected by the far transmission pressure gauge, wherein the two variable frequency pumps have different power, a variable frequency pump with larger power works as a main pump, and a variable frequency pump with smaller power works as an auxiliary pump. The constant pressure water supply device control system with the variable frequency auxiliary pumps has the advantages that when low water supply pressure is requested, the variable frequency pump with the small power supplies pressure, and therefore a redundancy rate of the device power is low, energy consumption is moderate, and the problem of boosting the pressure can be solved effectively.
Description
Technical field
The utility model relates to a kind of supply equipment, relates in particular to a kind of constant pressure water supply equipment control system with the frequency conversion auxiliary pump.
Background technology
Existing constant pressure water supply equipment generally adopts " control is many " pattern, dispose a variable frequency pump and Duo Tai general pump in this " control is many " pattern, when needs supply water, at first start variable frequency pump, when the pressure of supply water increase in demand, the general pump quantity of the operation of increasing input gradually, when the pressure of supply water demand reduces, reduce gradually first the general pump quantity that puts into operation, when the pressure of supply water demand is lower than certain value, variable frequency pump is also closed; The problem that this operational mode exists is: the power of variable frequency pump is bad to be determined, if power is too little, the frequency conversion effect of variable frequency pump is difficult to performance, do not have corresponding effect, if power is too large, when the pressure of supply water demand is low, the power redundancy degree of equipment is larger, cause unnecessary energy consumption, and, the powerful variable frequency pump problem that easy build-up of pressure is leapt high when starting.
The utility model content
For the problem in the background technology, the utility model proposes a kind of constant pressure water supply equipment control system with the frequency conversion auxiliary pump, comprising: controller, two variable frequency pumps, many general pumps and distance-transmission pressure gauge; Distance-transmission pressure gauge is installed on the place, water side of equipment, in order to gather discharge pressure; Distance-transmission pressure gauge and controller communication connection; Two variable frequency pumps of Data Control that controller collects according to distance-transmission pressure gauge and the duty of Duo Tai general pump; Wherein, the power of two variable frequency pumps is different, and the larger variable frequency pump of power is as main pump, and lower-powered variable frequency pump is as auxiliary pump.
Useful technique effect of the present utility model is: when the pressure of supply water demand was low, by low power variable frequency pump voltage supply, the plant capacity redundancy was lower, and energy consumption is moderate, and can effectively solve the problem that pressure is leapt high.

Fig. 1, structural representation of the present utility model.
The specific embodiment
Scheme of the present utility model is: a kind of constant pressure water supply equipment control system with the frequency conversion auxiliary pump comprises: controller 1, two variable frequency pumps 2, many general pumps 3 and distance-transmission pressure gauge 4; Distance-transmission pressure gauge 4 is installed on the place, water side of equipment, in order to gather discharge pressure; Distance-transmission pressure gauge 4 and controller 1 communication connection; Two variable frequency pumps 2 of Data Control that controller 1 collects according to distance-transmission pressure gauge 4 and the duty of Duo Tai general pump 3; Wherein, the power of two variable frequency pumps 2 is different, and the larger variable frequency pump 2 of power is as main pump, and lower-powered variable frequency pump 2 is as auxiliary pump.
Operating principle of the present utility model is: 1) when equipment is started working, at first start auxiliary pump; After auxiliary pump put into operation, when the pressure of supply water demand fluctuateed in auxiliary pump load capacity scope, equipment was kept auxiliary pump isolated operation state all the time; This just can make the power redundancy of equipment and energy consumption all be in preferably state, simultaneously, efficiently solves directly access and the pressure that the causes problem of leaping high of powerful variable frequency pump 2;
2) after the pressure of supply water demand exceeds auxiliary pump load capacity scope, start the main pump operation, and close auxiliary pump, the main pump isolated operation; After the main pump isolated operation, two kinds of situations may occur, a kind of situation is that pressure of supply water increases, and another kind of situation is that pressure of supply water continues to descend; For the first situation, after pressure of supply water reached a setting value and postpones certain hour, controller 1 switched to again auxiliary pump isolated operation state with the mode of operation of equipment; After switching to auxiliary pump isolated operation state, constant if pressure of supply water continues to keep, then close auxiliary pump; For the second situation, controller 1 changes according to pressure, and general pump 3 quantity of the operation of increasing input gradually are to satisfy the pressure of supply water demand..
3) when having general pump 3 to put into operation, if pressure of supply water continue to rise or when remaining near the goal pressure, then reduce gradually general pump 3 quantity that put into operation, device replied is to main pump isolated operation state; After returning back to main pump isolated operation state, if pressure of supply water still is in steady state, then postpone certain hour after, controller 1 switches to again auxiliary pump isolated operation state with the mode of operation of equipment; After switching to auxiliary pump isolated operation state, constant if pressure of supply water continues, then after postponing certain hour, close auxiliary pump.
After adopting scheme of the present utility model, can make the redundant and energy consumption of pressure of supply water demand plant capacity hour all be in preferably state, reduction equipment running cost.
