Problems solved by technology
Therefore, regardless of the high-pressure or medium-pressure pumps, the number of starts and stops of the No. 1 water pump is much higher than that of the other three pumps. When the water pressure is unstable, it will cause it to fail first; when the No. 1 water pump reports failure, the No. 2 and No. 3 pumps will take over in turn. The position of the No. 1 water pump frequently starts and stops and reports a fault, which leads to the paralysis of the entire water supply system
[0003] However, in the prior art, due to the rapid change of the water pressure in the pipeline, the water pump starts and stops frequently, and then the soft starter frequently starts and stops faults, so the water pump starts and stops frequently, and the soft starter frequently starts and stops faults, resulting in the paralysis of the entire water supply system

The invention relates to the field of water supply adjusting stations, and discloses a water pump for a water supply conditioning station. The water pump comprises a soft starter and medium-pressure water pumps, wherein one side of the soft starter is connected with a first pointer, the other side of the first pointer is connected with high-pressure water pumps, the other side of the soft starteris connected with a second pointer, the other side of the second pointer is connected with the medium-pressure water pumps, the three high-pressure water pumps are in telecommunication connection withthree telecommunication interfaces on the other side of the first pointer, so that the three high-pressure water pumps are started in turn by means of the first pointer, and the working condition that the water pump started firstly is stopped finally is realized by using the arrangement combination; and then the four medium-pressure water pumps are in telecommunication connection with four telecommunication interfaces on the other side of the second pointer, so that the four medium-pressure water pumps are started and stopped in turn by means of the second pointer, the water pumps of the water supply adjusting station are started in turn, the frequent start and stop faults of the soft starter are reduced, and the water supply system tends to be stable.
Description
technical field [0001] The invention relates to a water supply regulating station, in particular to a water pump used in the water supply regulating station. Background technique [0002] The on-site high-pressure and medium-pressure water mainly rely on three high-pressure water pumps and four medium-pressure water pumps in the water supply regulation station to realize water pressure regulation and control; according to the actual water consumption on site, the water pressure in the pipeline changes quickly, so the pumps start and stop frequently, and then The soft starter frequently starts and stops faults; the starting sequence of the three high-pressure water pumps and the four medium-pressure water pumps is: start and stop the pumps with smaller numbers first. Therefore, regardless of the high-pressure or medium-pressure pumps, the number of starts and stops of the No. 1 water pump is much higher than that of the other three pumps. When the water pressure is unstable, ...
