2) go up the watering time of setting, for example: the watering time that is made as 10 minutes.
3. press start button (QA), auxiliary reclay (ZJ) coil gets electric, its contact (ZJ
1) and (ZJ
2) closure, unclamp start button (QA), contact (ZJ
1) self-insurance, hold-in winding (ZJ) has electricity, contact (ZJ
2) closure, time-delay relay (SJ
1) coil gets electricly, delays time after 6 seconds time-delay relay (SJ
1) adhesive, its contact (SJ
1-1) and (SJ
1-2) closure; The coil of AC vacuum contactor (CJ) gets electric, main contacts (CJ
1, CJ
2) closure, dc motor (ZD) entry into service, drive water pump pulley (12) by V-belt motor pulley (2), driving water pump (11) starts working, by the water suction water pump (11) of suction line (15) with water tank (7), be discharged to water pipe (16) and enter arc sparge pipe (9), form water curtain, realize full face even sprinkling through shower nozzle (20) ejection that nebulizes.。
4. time-delay relay contact (SJ
12) closure makes time-delay relay (SJ
