According to the control method of the indirect air cooling cleaning system, the automatic running can be achieved, the efficiency is high, and the full power generation of a generating unit can be effectively guaranteed.
Description
Technical field
The present invention relates to a kind of control method of purging system, relate in particular to a kind of control method of indirect air cooling tube bank internal washing system.
Background technology
The operation principle of surface-type indirect air cooling system is: recirculated cooling water in surface condenser by metal surface and turbine discharge heat exchange, with cooling vapour side steam discharge; Recirculated water after being heated is delivered to air cooling tower by water circulating pump, in air cooling heat radiator, by metal wall and air, carries out heat exchange, is returned to condenser again continue cooling turbine discharge by the cooled recirculated water of air.The cooling water system of indirect air cooling forms a closed cycle.The control method to indirect air cooling tube bank internal washing system having is now mostly that manual, such operating efficiency is not high, needs a large amount of manpower and materials.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, a kind of automatic operation is provided, efficiency is high, strong guarantee generating set completely send out between the control method of cold rinse system.
The technical solution adopted for the present invention to solve the technical problems is: the control method of a kind of cold rinse system, and control method is as follows:
A, preparatory stage: I, operation switch board, starts water pump; Whether II, drive up and down put in place simultaneously, if the program that puts in place continues, opens upper/lower guide locking device if not in place, automatically moves to after putting in place and close upper/lower guide locking device; III, whether electric three passes ball valve closes, if bolt down procedure continues, if close; IV, dihedral injection nozzle carrier travelling car, whether at upper limit, if the program that puts in place continues, moves to upper limit if not in place; V, whether dihedral injection nozzle carrier is at 0 degree, if program continues, if not dihedral injection nozzle carrier moves to 0 degree;
B, wash phase: I, open dihedral injection nozzle carrier to 90 degree; II, opens electric three passes ball valve first side; III, travelling car moves to lower limit from top to bottom; IV, opens electric three passes ball valve second side; V, travelling car moves to upper limit from bottom to top; VI, closes electric three passes ball valve; VII, closes dihedral injection nozzle carrier to 0 degree;
C, shift phase: I, open upper/lower guide locking device; II, moves horizontally cleaning device, and upper and lower horizontal automatic drive device simultaneously normal speed moves to first limit switch; III, upper and lower horizontal automatic drive device low cruise to the second limit switch; IV, closes upper/lower guide locking device;
D, be repeated to a stage II.
Further comprise, if the upper/lower guide locking device of opening not in place in described a stage II, that has put in place does not open, and operation is simultaneously urged to spacing up and down, to spacing not moving, closes upper/lower guide locking device simultaneously.
Further comprise, described method also can manual mode be carried out.
