Principle of the present utility model and the course of work:
The utility model is taken into account and is solved summer environment sweltering heat, generating set vacuum significantly reduces, cause the not upper load of generating set band, can not meet the practical problem of electrical network actual demand, when rinse-system carries out, play the surface temperature of cooling Air-Cooling Island fin, can play the effect that improves generating set vacuum, meet generating set generating at full capacity under the environment of sweltering heat in summer, meet the demand of electrical network, mentality of designing is novel.
Referring to Fig. 1, the utility model is respectively installed a set of automatic flushing apparatus to the one side of each heat-sink unit of Air-Cooling Island, and this installs parallel, employing gear reduction unit drives, one side left and right is rinsed back and forth, and single programming washing time is 10 minutes, also can adjust the time according to actual conditions in addition; After operation remote operation cleaning procedure, two unit one sides rinse and carry out simultaneously, after this program executes, automatically switch to lower two unit one sides and rinse beginning simultaneously, meanwhile, also can adjust according to actual needs flushing element number.Also can adjust cleaning procedure according to equipment situation.The complete time of the whole cleaning procedures of single unit according to demand the number of devices of side specifically do not rinse design 160-240 minute not etc.System is by upper and lower guide rail and rinse support, mechanical transfer (comprising reductor etc.) forms.Upper and lower guide rail level is arranged on the above and below of each cooling unit, rinsing support is placed on upper and lower guide rail, by an AC electrical reductor machine, dragged, can according to the speed left and right horizontal of setting, move along upper and lower guide rail, motor carries out speed regulating control by frequency converter;
On flushing support, be evenly distributed 45-60 shower nozzle, when high-pressure water valve is opened, one or two unit rinse one by one in order by the program of setting, and shower nozzle is sprayed water simultaneously, realizes the flushing of cooling unit and cooling; Water under high pressure from high-pressure hydraulic pump is connected to the lower end of flusher through high-pressure water valve, hose;
At the left and right two ends of each unit lower guideway mounting limit switch, for limiting the left and right moving range of flusher, to control loop, send instruction simultaneously.
Air-Cooling Island auto-flushing, cooling system enter PLC and control, and can realize Long-distance Control, operation.In centralized control room, should be able to realize the automatic starting and stopping work of Air-Cooling Island self-stripping system, system runtime system fault-signal and running status should feed back to central control room in time.System is simple to operate, fault immediate feedback.System possesses two kinds of operational modes: fully automatic mode and manual mode, and system is when fully automatic mode, and flushing device moves left and right flusher automatically, automatically switches to next program flushing and carry out after a local cleaning procedure finishes.This auto-flushing program all adopts DCS interface, a distant place automatically to control.This design has been improved numerous disadvantages of current domestic flusher service condition, equipment is reliable, we have taken into account Air-cooled Unit spike in summer cooling effect simultaneously, can guarantee generating set energy normal full load operation under hot environment in summer, and input cost is lower.
The utility model can move left and right horizontal according to actual needs the cooling that is designed to move up and down along heat-sink unit and rinse forms of motion.
Referring to Fig. 2, control circuit figure of the present utility model:
The utility model adopt L1 L2 L3 three phase mains, and be connected to power switch QS, from L1 coupling, connect control power supply, by controlling power safety FU2 and controlling power switch FR, be connected with the second contactor KM2 with the first contactor KM1.After the flushing support 3 of take below moves right, to left movement, be example again, the course of work of the present utility model of explaining:
1) start to the right:
First by bottom left start button SB1, left start button SB1 normally closed interlock first disconnects, the interlocking of realization to the second contactor KM2, simultaneously left start button SB1 normally open contact is closed, thus the first contactor KM1 coil obtains electric, and then make the auxiliary contact of the first contactor KM1 closed, realize self-sustaining, in addition, the main contact of the first contactor KM1 is closed, the locking contact of the first contactor KM1 disconnects, and realizes the interlocking to the second contactor KM2; After the auxiliary contact closure and main contact closure of the first contactor KM1, alternating current generator M starts, and works to the right continuously; When rinsing support 3, move right after right limit switch XC2, right limit switch XC2 disconnects, alternating current generator M stall.
2) start left:
First by bottom right start button SB2, right start button SB2 normally closed interlock first disconnects, the interlocking of realization to the first contactor KM1, simultaneously right start button SB2 normally open contact is closed, thus the second contactor KM2 coil obtains electric, and then make the auxiliary contact of the second contactor KM2 closed, realize self-sustaining, in addition, the main contact of the second contactor KM2 is closed, the locking contact of the second contactor KM2 disconnects, and realizes the interlocking to the first contactor KM1; After the auxiliary contact closure and main contact closure of the second contactor KM2, alternating current generator M starts, and works left continuously; When rinsing support 3, move to left after left limit switch XC1, left limit switch XC1 disconnects, alternating current generator M stall;
3) emergent stopping is controlled:
When running into emergency and need to stop immediately, press danger button SB3, whole control circuit dead electricity, each contact of contactor resets, the stall of alternating current generator M dead electricity;
4) it should be noted that:
4-1) main circuit must commutation (be that V is mutually constant, U phase is exchanged mutually with W), could realize control;
4-2) during wiring, contactor self-locking contact can not be exchanged, otherwise can only crawl;
4-3) control coil of contactor is 380V;
4-4) power switch FR should select 380V switch.
5) if realize left and right Automatic continuous and swing, can by left limit switch XC1 often open node and right start button SB2 is in parallel, by right limit switch XC2 often open node and left start button SB1 is in parallel.
6) if realize in dcs DCS, local control box need not become, only the control instruction of dcs DCS need be controlled to auxiliary reclay, by auxiliary reclay often open node and left start button SB1 right start button SB2 in parallel.
If realized with dcs DCS, case can adopt rotating control module (rotating that can realize the following motor of 7.5KW is controlled) on the spot, the direct Access Control module of dcs DCS instruction realizes above-mentioned functions (without auxiliary reclay), and dcs DCS directly exports 24V control instruction and directly drives rotating control module.
Above content is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the protection domain of the utility model claims.
