Abstract
The utility model relates to a dual-core driving pipe-network pressure-add water supply device, comprising frequency converters, a contactor, a programmable controller, an MODBUS communication cable and a water pump. An electrical cabinet is provided with two sets of frequency converters which are connected to the water pump through the contactor and simultaneously connected to the programmable controller through the MODBUS communication cable, the programmable controller can be simultaneously connected to the contactor so as to ensure that the programmable controller can monitor the operating states of the two sets of frequency converters in real time. When the frequency converting driving device of one of the frequency converter breaks down during operation, the system can automatically switches the water pump to the other set of the frequency converting driving device for continuing the operation. The dual-core driving pipe-network pressure-add water supply device of the utility model has the advantages of simple integral structure, good stability and high reliability, truly achieves the significance of standby from the aspect of electrical control, and ensures the whole set of equipment to be operated more reliably, and in addition, by the arrangement of the dual-core drive, the equipment has the characteristics of easy implementation and operation, lower cost, easy quantity production and great practical value.
Description
Technical field
The utility model relates to the water supply installation of urban skyscraper, relates in particular to double-core and drives pipe network pressure-superposed water supply installation.
Background technology
Pipe network Pressure-superposed water supply equipment is used in above the second pressure water supply of little high level in city or highrise building.Increase the reliability that stand by pump increases unit though supply equipment has adopted in the market, when its core drive system fault, complete equipment still can not move.So strengthen the equipment operational reliability, the equipment of keeping uninterruptedly supplies water, and is the emphasis that people pay close attention to, be the target that the device fabrication merchant pursues.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of double-core to drive pipe network pressure-superposed water supply installation, strengthens the stability of a system and the reliability of pipe network Pressure-superposed water supply equipment aspect the second pressure water supply of little high level in city or highrise building.
Double-core described in the utility model drives pipe network pressure-superposed water supply installation, includes frequency converter, contactor, programmable logic controller, MODBUS communication cable and water pump and forms.Electrical control cubicles disposes two cover frequency converters, and two cover frequency converters are connected to water pump by contactor, are connected to programmable logic controller by the MODBUS communication cable again simultaneously, and programmable logic controller also is connected to contactor simultaneously.Frequency converters are overlapped in electrical control cubicles configuration two, and two cover frequency converters carry out the MODBUS communication with programmable logic controller simultaneously by the MODBUS communication cable, the running status that allows programmable logic controller monitoring in real time two overlap frequency converters.Break down when one of them frequency-conversion drive apparatus is in operation, system can switch to an other cover frequency-conversion drive apparatus to water pump automatically and continue operation.Main innovate point of the present utility model: 1, electrical control cubicles configuration two cover frequency converters; 2, two cover frequency converters carry out the MODBUS communication with PLC simultaneously, and PLC controls simultaneously to two cover frequency converters; 3, two cover frequency converters regularly switch, and are recycling, strengthen the physical life of system.4, really realize the standby meaning of complete equipment device, the equipment operational reliability of allowing is further perfect.
Double-core described in the utility model drives pipe network pressure-superposed water supply installation, overall structure is simple, good stability, the reliability height has really been realized standby meaning from automatically controlled aspect, makes the complete equipment operation more reliable, equipment configuration double-core drives and is easy to realize operation, expense is lower, is easy to form produce in batches, has great practical value.
Description of drawings:
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: double-core described in the utility model drives pipe network pressure-superposed water supply installation, includes frequency converter 1, contactor 2, programmable logic controller 3, MODBUS communication cable 4 and water pump 5 and forms.Electrical control cubicles disposes two cover frequency converters, 1, two cover frequency converter 1 and is connected to water pump 5 by contactor 2, is connected to programmable logic controller 3 by MODBUS communication cable 4 again simultaneously, and programmable logic controller 3 also is connected to contactor 2 simultaneously.We can say that also electrical control cubicles configuration two is overlapped frequency converters 1, two cover frequency converter 1 and carried out the MODBUS communication with programmable logic controller 3 simultaneously by MODBUS communication cable 4, the running status that allows programmable logic controller 3 monitoring in real time two overlap frequency converters 1.Break down when the frequency-conversion drive apparatus of one of them frequency converter 1 is in operation, system can switch to an other cover frequency-conversion drive apparatus to water pump 5 automatically and continue operation.Main innovate point of the present utility model: 1, electrical control cubicles configuration two cover frequency converters; 2, two cover frequency converters carry out the MODBUS communication with PLC simultaneously, and PLC controls simultaneously to two cover frequency converters; 3, two cover frequency converters regularly switch, and are recycling, strengthen the physical life of system.4, really realize the standby meaning of complete equipment device, the equipment operational reliability of allowing is further perfect.Double-core described in the utility model drives pipe network pressure-superposed water supply installation, overall structure is simple, good stability, the reliability height has really been realized standby meaning from automatically controlled aspect, makes the complete equipment operation more reliable, equipment configuration double-core drives and is easy to realize operation, expense is lower, is easy to form produce in batches, has great practical value.
