Abstract
The utility model discloses a constant-pressure water-supplying control device, comprising a three-phase power supply, and also comprising a frequency converter, a microcomputer, a water pump and a pressure transmitter, wherein the output end of the three-phase power supply is communicated with the input ends of the microcomputer and the frequency converter; the output end of the frequency converter is communicated with the water pump; and the signal input end of the microcomputer is communicated with the signal output end of the pressure transmitter, and the signal output end of the microcomputer is communicated with the frequency converter. Compared with the existing water-supplying control device, the constant-pressure water-supplying control device also comprises the frequency converter, the microcomputer, the water pump and the pressure transmitter; and data collected by the pressure transmitter is processed by the microcomputer, then soft start of the water pump is realized by the frequency converter, and further the water-supplying pressure is adjusted. The constant-pressure water-supplying control device has the advantages of simple operation, low failure rate, high accuracy, small occupied space, strong flexibility, less investment, high efficiency and energy conservation.
Description
Technical field
The utility model relates to a kind of water supply control appliance, relates in particular to a kind of constant pressure water supply control device.
Background technology
Traditional water pump water supply system is made up of water pump and pipe network etc. at present, and pressure of supply water can not be regulated, and the variation of water supply volume causes the variation significantly of hydraulic pressure; Cause conduit failure when pressure is big, power consumption is big, if set up water tank; Then the high floor space of cost is big, and starting of pump station is frequent, because the influence of water hammer effect; Water pump damages easily, and maintenance cost is high.For head it off, some adopts PLC and frequency converter to solve this problem, but the method complicated operation needs the professional to carry out the parameter setting at every turn, is out of order easily, inconvenient intuitive operation, and maintenance cost is high.
The utility model content
To the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of can the variation according to the water yield to regulate pressure of supply water, and easy to operate, directly perceived, the constant pressure water supply control device that economy is high, stability is strong, maintenance cost is low.
The technical scheme of the utility model is: a kind of constant pressure water supply control device; Comprise three phase mains; Also comprise frequency converter, micro computer, water pump and pressure transmitter, said three-phase power output end is communicated with the input of micro computer and frequency converter, and the output of said frequency converter is communicated with water pump; Said micro computer signal input part is communicated with the signal output part of pressure transmitter, and the signal output part of micro computer is communicated with frequency converter.
As preferably, connect the 24V dc source of promising its work power supply on the said pressure transmitter.
As preferably, said water pump is the work unit that governor impeller, constant speed pump, water-delivery pump are formed.
The beneficial effect of the utility model is: the utility model also comprises frequency converter, micro computer, water pump and pressure transmitter; The data that pressure transmitter is collected are handled through micro computer, realized the water pump soft start through frequency converter again, and then regulate pressure of supply water; Adopt micro computer to replace traditional PLC control; The utility model is simple to operate, and fault rate is low, and precision is high, floor space is little, flexibility is strong, small investment, energy-efficient.
