Description
Technical field
The utility model relates to intelligent heat-exchange machine set technology field, especially a kind of intelligent heat-exchange unit secondary net water pump electric controller.
Background technique
Along with market increasingly high to heat supply quality, environmental protection and energy-conservation requirement; Original, simple heat-supplying mode can not satisfy the demand in heat supply market; The intelligent heat-exchange unit that has intelligent control system is very universal, the automatic controlling level height of this type unit, good energy-conserving effect, system's security of operation, stable, and the convenience on the maintenance and management all substantially exceeds traditional heat-supplying mode; Simultaneously; Because the height of system is intelligent, and the operation of heat exchange station and maintenance cost are reduced significantly, be the inexorable trend of heat supply development.But; Because the recycle pump and the small pump of this intelligent heat-exchange unit secondary net all are to control startup, rotating speed and parking by central control unit through frequency variator; In case central control unit or frequency variator break down; To cause the circulation of secondary net to be ended, high temperature vapour, the water at this moment once netted in the circulation loop will cause badly damaged to the heat exchanger of intelligent heat-exchange unit.In addition; In the Installation and Debugging process of intelligent heat-exchange unit; Will be with being full of cold water in the system of secondary webmaster road, repeated multiple times is opened or is stopped secondary net recycle pump, carries out could normally moving after the blowdown repeatedly; The hand switches that adopt carry out power frequency startup or shut-down operation to the recycle pump of secondary net more in this process; This Starting mode causes secondary net circulating pump motor easily and damages and influence the stable of electrical network, and the water hammer effect that the recycle pump of secondary net is produced when stopping will impact to the heat exchanger of intelligent heat-exchange unit, the valve in the pipeline, damages the working life of heat exchange unit or shortening heat exchange unit.
The model utility content
The technical problem that model utility will solve is: overcome deficiency of the prior art; A kind of intelligent heat-exchange unit secondary net water pump electric controller is provided; When the central control unit of intelligent heat-exchange unit or frequency variator break down; This device still can to the recycle pump of secondary net and small pump normally starts or the control of stopping, and prevents that net height temperature vapour, the water heat exchanging device from causing permanent damage.
The technological scheme that the technical solution problem is taked: intelligent heat-exchange unit secondary net water pump electric controller; Comprise recycle pump and small pump; On the circuit between recycle pump and power supply, be connected in series circulation automatic frequency-conversion starter; On the circuit between small pump and power supply, be connected in series moisturizing automatic frequency-conversion starter; The control signal input end of circulation automatic frequency-conversion starter and moisturizing automatic frequency-conversion starter connects the corresponding signal output terminal of central control unit respectively; On the circuit between recycle pump and power supply, also be provided with the recycle pump power frequency parallelly connected and manually boot switch, on the circuit between small pump and power supply, also be provided with the small pump power frequency parallelly connected and manually boot switch with moisturizing automatic frequency-conversion starter with the automatic frequency-conversion starter that circulates.
Improvement as the utility model: manually boot in the recycle pump power frequency and also to be provided with soft initiator between switch and recycle pump.
Further improvement as the utility model: said soft initiator is a bypass operation soft initiator.
Beneficial effect: the intelligent heat-exchange unit secondary net water pump electric controller of the utility model; Owing to adopted said intelligent heat-exchange unit secondary net water pump electric controller to comprise recycle pump and small pump; On the circuit between recycle pump and power supply, be connected in series circulation automatic frequency-conversion starter; On the circuit between small pump and power supply, be connected in series moisturizing automatic frequency-conversion starter; The control signal input end of circulation automatic frequency-conversion starter and moisturizing automatic frequency-conversion starter connects the corresponding signal output terminal of central control unit respectively; On the circuit between recycle pump and power supply, also be provided with the recycle pump power frequency parallelly connected and manually boot switch with the automatic frequency-conversion starter that circulates; On the circuit between small pump and power supply, also be provided with the technological scheme that the small pump power frequency parallelly connected with moisturizing automatic frequency-conversion starter manually boots switch; When the central control unit of intelligent heat-exchange unit or frequency variator broke down, this device can manually boot switch and small pump power frequency through the recycle pump power frequency and manually boot switch to the recycle pump of secondary net with small pump normally starts or the control of stopping, and prevents that net height temperature vapour, the water heat exchanging device from causing permanent damage; Owing to adopted in the recycle pump power frequency and manually booted the technical characteristics that also is provided with soft initiator between switch and recycle pump; Preventing on the one hand that power frequency from starting pump motor caused damages or the stabilization of power grids is impacted; The water hammer effect heat exchanging device, valve and the pipeline that produce when preventing secondary net recycle pump hard stop car on the other hand cause damage, have improved the Security and the stability of intelligent heat-exchange unit; Because having adopted said soft initiator is the technical characteristics of bypass operation soft initiator, prevents the long-term on-line operation of controllable silicon in the soft initiator, has prolonged the working life of soft initiator, has reduced energy consumption.
