Submersible pump water supply station out of the pool water level settings
A submersible pump water supply pump station into the pool water level should be used according to the following provisions:
1, flood water level: According to the provisions of Table 3.1.1 of this specification.
2, the design level: from the rivers, lakes or reservoirs to take water, take water to ensure that the rate of 95% to 97% of the average daily or ten days
Water level; water from the channel, take the channel through the design of the water level when the flow.
3, the maximum operating water level: from the rivers, lakes, water, take the return period of 10 to 20 years a flood daily average water level;
When water is taken from the reservoir, it is determined according to the storage capacity of the reservoir; when the water is taken from the channel, the water level of the channel is increased when the flow is increased.
4, the minimum operating water level: water from the river, lake or reservoir, the water source to ensure that the rate of 97% to 99% of the lowest level
Water level; water from the channel, the channel through a single pump flow when the water level.
5, the average water level: water from a river, lake or reservoir, take years of average water level; from the channel when taking water, take the canal
The water level when the road passes through the uniform flow.
6, the water level should be deducted from the water intake into the pool of water loss. From the river bed instability of water, the Shang
Should take into account the impact of river bed changes, the water tank can be used as the corresponding characteristics of the water level.
Second, the submersible water pump station water level should be used according to the following provisions:
1, the highest water level: check the water level of the water channel.
2, the design of water level: take the pump design flow corresponding to the water level.
3, the maximum operating water level: take the pump station to increase the flow of the corresponding water level.
4, the minimum operating water level: take a pump with a single pump corresponding to the water level.
5, uniform water level: take the water channel through the uniform flow of water level
