Description
Technical field
This utility model relates to a kind of novel full frequency conversion digital integration network pressure-superposition water supply equipment.
Background technology
Equipment on market mostly is a Frequency Converter Control multiple stage water pump, and its pump group control circuit is by a universal frequency converter
Form with main control unit and corresponding external relay type electrical combination.In actual motion, the most only realize separate unit water
The frequency control of pump runs, and in pump group, other work water pump is then in power frequency operation state.Even if every supporting change of water pump
Frequently device, but complete machine main control unit still only one of which, and peripheral relay circuit yet suffers from, the running of water pump is still
Need to assist realization by relay circuit.Complete machine integration degree is low, and control system cannot be standby, and reliability is the strongest.Cause
This urgently makes improvements, and designs novel full frequency conversion digital integration network pressure-superposition water supply equipment, and furnish good supplies to water requirement.
Summary of the invention
The purpose of this utility model is the separate unit water in solution prior art existing for a Frequency Converter Control multiple stage water pump
The frequency control of pump runs, the problem that in pump group, other work water pump is then in power frequency operation state, it is provided that a kind of guarantee is supplied water
Pressure is constant, adherence pressure control accuracy and overall efficiency, it is achieved full VFC, reaches the full frequency conversion of real energy-saving effect
Digital integration network pressure-superposition water supply equipment.This utility model designs a kind of novel complete pipe network pressure-superposed feedwater of frequency conversion digital integration and sets
Standby, including control system, pressure sensor device, super-high pressure protecting device, stable-pressure device, outfall sewer, pump out water valve group, pressurization
Pump group, pump water inlet valve group, water inlet manifold, steady flow compensation device, liquid level detector, negative pressure preventing module, defecator, anti-down
Stream device, it is characterised in that: on every water pump, connect a special frequency-variable controller of digital integration water pump, digital integration water pump
Special frequency-variable controller connects the pressure transducer in the exit of this water pump, all special frequency-variable controllers of digital integration water pump
Connected by communication bus.The utility model has the advantages that every water pump of full converting operation all configures a digital integration water pump special
Frequency-variable controller, controls every water pump and all runs in its efficient district, it is achieved full VFC, thus reaches more energy-conservation mesh
's.It is identical that efficiency shares out equally function every pump frequency conversion operation operating frequency, and this function can overcome because the minimum startup of motor becomes
The restriction of frequency and the waste of energy that causes, for the distinctive power saving function of full frequency-conversion water supply system；Emergency measure function works as frequency conversion control
When device processed breaks down, can switch to MANUAL CONTROL mode run, when frequency converter failure, changeable converter run；Work as pressure
When force transducer breaks down, controller controls converter fixed frequency and runs；Integration degree height equipment is integral type structure,
Controller and converter are integrated and are integrated at pump motor, decrease component number in switch board, line arrangement letter
Single, easy to maintenance, safe and reliable.
Accompanying drawing explanation
Accompanying drawing 1 be section of structure of the present utility model (1, control system, 2, pressure sensor device, 3, supertension protects
Protection unit, 4, stable-pressure device, 5, outfall sewer, 6, pump out water valve group, 7, force (forcing) pump group, 8, pump water inlet valve group, 9, water inlet manifold,
10, steady flow compensation device, 11, liquid level detector, 12, negative pressure preventing module, 13 defecators, 14, anti-backflow device,
15, the special frequency-variable controller of water pump).
Detailed description of the invention
A kind of novel full frequency conversion digital integration network pressure-superposition water supply equipment in figure, including control system, pressure sensing dress
Put, super-high pressure protecting device, stable-pressure device, outfall sewer, pump out water valve group, force (forcing) pump group, pump water inlet valve group, water inlet manifold,
Steady flow compensation device, liquid level detector, negative pressure preventing module, defecator, anti-backflow device, it is characterised in that: at every water
Connecting a special frequency-variable controller of digital integration water pump on pump, the special frequency-variable controller of digital integration water pump connects this water pump
The pressure transducer in exit, all special frequency-variable controllers of digital integration water pump are connected by communication bus.
Full frequency conversion digital integration pipe network Pressure-superposed water supply equipment uses water pump variable frequency control system special, and this system uses a pump
The mode forming control system of one frequency conversion, by the built-in mechanics of communication of converter or the data acquisition of controller and logic control merit
Can, it is achieved the automatic frequency-conversion Isobarically Control of system.The discharge pressure of system detection pipe network, is controlled by PID function computing output
The tach signal of pump motor, and judge to control the use number of units of water pump by rotating speed and hydraulic pressure, make system constant-pressure operation；Control
System is integrated with various water supply defencive function, makes supply equipment be in optimal operational condition all the time, reduce energy waste, thus
Reach energy-saving effect.
