Three-pump diversified pumping station and method of control of the three-pump diversified pumping station operation

摘要

trzypompowa pumping station, which has two identical pumps with varied output of approximately 0.5 maximum efficiency pump rooms and nominal lifting height close to the maximum lifting height of the pump room and one the output of approximately the same d about 0.25 maximum efficiency pumping stations, characterized by that,that the nominal amount of lifting pump (1) with a capacity of approximately 0.25 maximum efficiency of pumping station is higher than the nominal height lifting pumps (2, 3) for output of approximately 0.5 maximum efficiency pump rooms, with pumps (1, 2) have the regulo wanu0105 speed, and the pump (2) for output of close to 0.5 maximum efficiency pumping stations has programmed frequency power supply, the pump (2), depending on the efficiency of the pompowniu0119.way control work trzypompowej pumping stations varied, where wydajnou015bciowy working range of pumping stations is divided into five natural ranges, which are: in the first pump - pump capacity of close to 0.25 maximum efficiency in the pump room, the second pump for output of close to 0.5 maximum efficiency pump rooms,in the third pump efficiency of close to 0.25 maximum yield of pumping stations and pump efficiency of close to 0.5 maximum efficiency pump rooms, in the fourth - pumps output of close to 0.5 maximum efficiency in the pump room, the fifth - pump capacity of close to 0.25 maximum productivity and two pumps pumping station output of close to 0.5 maximum productivity and maintenance of pump room, pumping system characteristics required in machinery is carried out by modifying the rotational speed of pumps, is that in the interval ah, the third (iii) and fifth (v), in which work pumps (1, 2) with adjustable speedfor the pump (2) for output of approximately 0.5 maximum efficiency pump room program frequency power supply, the pump (2), depending on the efficiency of the pompowniu0119.
