Description

A kind of microcomputer controls full variable-frequency speed-adjusting supply equipment
Technical field
The utility model belongs to supply equipment technical field, and in particular to one kind is supplied using micro-processor controlled full variable-frequency speed-adjusting Wetting system.
Background technology
Current municipal water supply and building supply water and use more:(1)Traditional work Frequency Conversion And Timing Water-Supplying Equipment(Become by main pump Frequency modulation is fast and increases and decreases to realize the constant of official website pressure from pump).With the increase of system water amount(Reduce), equipment increasing(Subtract) During pump, due to the power frequency startup from pump(Close)The fluctuation of flow system flow and hydraulic pressure can be caused, band is normally used to user To influence, and full voltage starting can also largely effect on the service life of pump motor;(2)Microcomputer is controlled in many frequency-changing water supply devices Main pump conversion frequencies are asynchronous with the conversion frequencies from pump, and loss of confluxing is big;And the pump of low-frequency operation does not run in high efficient district, makes Into the waste of the energy;(3)Special converter controls supply equipment, and only main pump enjoys pressure signal and control is from the start and stop of pump. The failover from pump can only be met, equipment can only be out of service when main pump breaks down, and is brought about great losses to user, and Unitary function cannot link with other equipment.
The content of the invention
Goal of the invention:The utility model purpose is in view of the shortcomings of the prior art, there is provided a kind of energy-efficient, stabilization Reliable microcomputer control full variable-frequency speed-adjusting supply equipment.
Technical scheme:A kind of microcomputer control full variable-frequency speed-adjusting supply equipment described in the utility model, including microcomputer control Cabinet, water inlet manifold, it is installed in parallel in some branch water pipes on water inlet manifold, some described outlets of branch water pipe are simultaneously Couple into outfall sewer, every described branch water pipe is provided with water pump, and integration is equipped with the pipeline of the water pump both sides Automatic regulating valve, is fixed with frequency converter on the motor side wall of the water pump, the water outlet of the outfall sewer is provided with electric contact Pressure gauge and pressure sensor, the microcomputer control cabinet are electrically connected with described frequency converter, are received from pressure by microcomputer control cabinet The signal of force snesor, controls the working condition of the frequency converter, and then control water supply condition.
Further, for ease of relatively low in pressure of supply water, continue normal water supply in the state of branch road water pump dormancy, it is described enter Auxiliary branch is also connected between supply mains and outfall sewer, the auxiliary branch is in parallel relationship with the branch water pipe, described Auxiliary branch is provided with the auxiliary pump of low discharge, and the auxiliary pump both sides of low discharge are provided with integrated automatic regulating valve.
Further, it is the control effect of raising valve body, the integrated automatic regulating valve is integral type butterfly valve check-valves, The integral type butterfly valve check-valves connects automatic adjusting control device, the automatic adjusting control device and the microcomputer control cabinet Electrical connection, the aperture of valve block is controlled by the automatic adjusting control device.
Further, the operation problem of water supply line is understood in real time for ease of surfaceman, the frequency converter is provided with change Frequency device accident warning device, the frequency converter failure warning device is electrically connected with the microcomputer control cabinet.
Further, understand the operation problem of water supply line in real time for ease of surfaceman or with water unit, and realize remote Journey remote control, is provided with short message resolver in the microcomputer control cabinet, MC35 modules, the MC35 modules are set in the short message resolver GSM BBPs including Mobile phone card and for parsing short message content.
Operation principle:When discharge pressure can not meet pressure requirements needed for user's least favorable water spot, microcomputer control cabinet is certainly Working as dynamic control setting is worth the operation of work starting mode of pump.Rising motor speed with frequency converter output frequency is accelerated.Work as water outlet pressure Power reaches default pressure value(Parameter presets)When, motor speed stabilization, work water pump is higher than the minimum acting of equipment Frequency(25Hz)Down coversion is run.
System water amount increases, and discharge pressure can not meet pressure requirements needed for user's least favorable water spot, and frequency converter is defeated Go out frequency to continue to raise, motor speed is accelerated, and equipment water supply flow increases, keep pressure of supply water constant.
After flow system flow exceedes work water pump metered flow operating point, separate unit water pump operation can not maintain the mesh of default Mark pressure, need to start second work water pump.By setup program, the crossover rate such as water pump switching that First is worked (is needed system Determined according to characteristic curve under pump different frequency), and second water pump also by automatic frequency-conversion to etc. crossover rate, then enter line frequency Rate is adjusted in synchronism, and equipment enters many work full frequency conversions of parallel connection of pumps, and equivalent synchronization, efficiency divides equally operating condition.
When system water amount is reduced, equipment outlet pressure is raised, and microcomputer control cabinet controls water pump frequency reducing to transport by setup program OK.When drop to subtract pump operation frequency when, the working barrel number of units for putting into operation is reduced automatically, return to a water pump metered flow scope Interior converting operation operating mode.
As system water amount is further reduced, working barrel is down to sleep frequency(Parameter presets), frequency converter dormancy, Working barrel is stalled, and is started the auxiliary pump frequency conversion of low discharge and is supplied water.Equipment monitoring discharge pressure change at any time by setup program, when outlet is pressed Power is less than the wake-up pressure value set by system(Parameter presets, generally the 90%~95% of equipment outlet pressure setting value) When, working barrel restarting operation, and repeat above-mentioned working procedure.
Beneficial effect:(1)Frequency converter is configured on every water pump in the present apparatus, the soft effect of soft stop can be played, greatly Extend the service life of water pump and reduce impact of the water hammer to pipe network greatly;One pump reaches 50Hz by time delay when increasing pump Afterwards, rapidly by foreground pump and latter pump frequency conversion to etc. crossover rate, equipment is in order to avoid water during work frequency conversion operating mode has been evaded completely The invalid acting of pump and the low-limit frequency that sets, make every water pump operate in high efficient district, reduce loss of confluxing;(2)This dress Put expanded function to enrich, be capable of achieving remote monitoring, and realize linking with other equipment.
