Abstract
The utility model discloses a kind of control system alleviating the surge of fire inspection cooling blower, relates to blower fan technical field, is particularly useful for fire inspection cooling blower.This control system is made up of blower fan, Y-piece, exhaust outlet, displacement transducer, modulating valve, pipeline, air sucking mouth, air sucking mouth, exhaust outlet place are provided with displacement transducer, displacement transducer is according to blower fan practical operation situation, setting warning shift value, when blower fan generation surge, alarm signal is passed to DCS by displacement transducer, and DCS processing signals also feeds back to modulating valve, automatic regulating valve door aperture, alleviates blower fan surge until blower fan normally runs.This control system effectively can improve fire inspection cooling blower operating conditions, alleviates the surge condition of fire inspection cooling blower, solves the under-supply problem of fire inspection cooling air because blower fan surge problems causes, and extends blower fan and flame detecting probe working life.
Description
Technical field
The utility model relates to blower fan technical field, is particularly useful for fire inspection cooling blower.
Background technique
Along with the development of science and technology, boiler flame monitoring has become the safety-monitoring index that power plant more and more pays close attention to, and flame detecting probe often burns, changes frequently, still can not effectively control.One that causes flame detecting probe to burn more common reason is that fire inspection cooling blower often occurs surge, causes fire detecting probe cooling quantity not sufficient, blast unstable, can not reach the cooling effect of expection.The surge of certain blower fan extensively exists, and Just because of this, solves blower fan surge, stablize blower fan applying working condition, prolongation service life of fan just seems very important.
Summary of the invention
Fire inspection cooling blower common is at present combined by a Y-piece by 2 Fans, reaches the using effect of the using and the reserved.
For Problems existing in current use, the utility model provides a kind of control system alleviating fire inspection cooling blower surge, strengthens fire inspection cooling blower stable conditions, extends blower fan and flame detecting probe working life.
For achieving the above object, the utility model provides following technological scheme.
The control system alleviating the surge of fire inspection cooling blower comprises blower fan (1), Y-piece (2), exhaust outlet (3), displacement transducer (4), modulating valve (5), pipeline (6), air sucking mouth (7), described blower fan (1) and Y-piece (2), by Flange joint, form existing conventional fire inspection cooling blower.
Further, pipeline (6) by welding or Flange joint between two fan induced draught mouths (7) and Y-piece (2) exhaust outlet, by Flange joint 1 modulating valve (5) on pipeline (6).
Further, modulating valve (5) is connected with DCS by cable, according to DCS instruction, can regulate aperture arbitrarily between 0-90 degree.
Further, displacement transducer (4) overlaps by support installing 1 in exhaust outlet (3) place, and 1 cover displacement transducer (4) is respectively installed by support by two fan induced draught mouth (7) places, and displacement transducer (4) is connected with DCS by cable.
Compared with examining cooling blower with existing conventional fire, the utility model is with displacement transducer (4), modulating valve (5), pipeline (6), its beneficial effect is when blower fan generation surge, displacement signal is changed into electrical signal by displacement transducer (4), sends DCS to by cable, DCS processing signals, fed back into the aperture of modulating valve (5), realize automatic control and adjustment, alleviate and eliminate the surge of fire inspection cooling blower with this, it also avoid the inconvenience of on-the-spot manual operation simultaneously.

Embodiment
Consult Figure of description, the utility model is set forth further.
As shown in Figure 1 and Figure 2, the control system alleviating the surge of fire inspection cooling blower comprises blower fan (1), Y-piece (2), exhaust outlet (3), displacement transducer (4), modulating valve (5), pipeline (6), air sucking mouth (7).Pipeline (6) by welding or Flange joint between the exhaust outlet of two fan induced draught mouths (7) and Y-piece (2), by Flange joint 1 modulating valve (5) on pipeline (6), displacement transducer (4) overlaps by support installing 1 in exhaust outlet (3) place, and 1 cover displacement transducer (4) is respectively installed by support by two fan induced draught mouth (7) places.
Displacement transducer (4) is according to blower fan practical operation situation, setting warning shift value, when blower fan generation surge, alarm signal is passed to DCS by displacement transducer (4), DCS processing signals also feeds back to modulating valve (5), automatic control and adjustment valve (5) aperture, alleviate blower fan surge till blower fan normally runs and no longer occurs alarm signal, control principle is as Fig. 3.
Claims (3)
