The intelligent end suction centrifugal pump of the variable-frequency motor driving of one.
Background technology
The import of end suction centrifugal pump is vertical with impeller direction, and import is located at impeller side one end.End suction centrifugal pump is applied to
The cold-warm water such as the conveying of industrial liquid and urban water supply and sewerage, skyscraper pressurized water supply, gardens sprinkling irrigation, fire fighting pressurization, heating follows
Ring is pressurized and coordinative composition of equipments and air-conditioner set circulation, cooling water conveying etc..
At present, during end suction centrifugal pump use, largely it is operated in power frequency rotating speed（50Hz）.And in practical application（Than
Such as building living water）In, water pump system need not be operated in metered flow, rated head in most of working time, and need
It is operated in partial load condition（The flow that i.e. actual pump system needs is less than less than metered flow or required lift
Rated head）, this can be realized by reducing the rotating speed of centrifugal pump.For centrifugal pump, power of motor consumption is approximate with turning
The cube of speed is directly proportional, and end suction centrifugal pump constant speed is operated in the waste that power frequency will cause the energy, so as to aggravate the dirt to environment
Dye, present solution method are to add the scheme of frequency-conversion control cabinet using common end suction centrifugal pump.With energy-conserving and environment-protective requirement not
Disconnected to improve, the situation using VFC end suction centrifugal pump and pump group is more and more, but because the introducing of frequency converter is, it is necessary to design
Independent frequency-conversion control cabinet is used for the electronic component for arranging frequency converter and some auxiliary, so that system becomes more complicated,
And because frequency-conversion control cabinet volume is larger so that whole variable frequency water pump system installing space substantially increases；On the other hand, due to
It is excellent that motor and frequency converter are that independent design, motor and frequency converter all do not operate at as a system under most of operating mode
Change state, efficiency is relatively low under Part load.
In constant pressure or constant-pressure drop end suction centrifugal pump system pipeline, the stream that is typically equipped with throttle valve control pipe network system
Amount.In constant temperature or constant difference end suction centrifugal pump system pipeline, be typically equipped with temperature-sensing valve adjustment pipe network system in fluid temperature
Degree.Intelligent end suction centrifugal pump can automatically adjust the rotating speed of water pump by sensor signal, so as to automatically adjust the flow of water pump and
Lift, ensure the constant pressure or constant-pressure drop, constant temperature or constant difference of setting.Therefore can save choke valve in system pipeline or
Person's temperature-sensing valve, save the material cost of whole system.
