Two, four kinds of water supply pattern summaries
1. the direct plural parallel stage supercharging of pipeline:
P1<P<P31<P32<P33, pipe network flow abundance, the pressure of supply water of low one-level anallobar is lower than the pressure of supply water setting value of high one-level anallobar, and first, second and third water pump row 51,52,53 start supercharging successively, and first and second motor operated valve 4,9 is opened.If water collect tank 8 interior liquid levels completely then second motor operated valve 9 are closed, and cut off the water collect tank inlet channel, otherwise second motor operated valve 9 is opened the water collect tank inlet channels, and water collect tank is filled.Tubing pump 13 is not worked all the time.
2. but directly moisturizing plural parallel stage supercharging of pipeline
P2<P<P1, when city planting ductwork flow or pressure were not enough, first motor operated valve 4 was opened, and continues to send water to first, second and third water pump row 51,52,53 water inlet ends.Tubing pump 13 work, simultaneously to first, second and third water pump row 51,52,53 water inlet end moisturizings, first, second and third water pump row 51,52,53 start supercharging from the water collect tank water intaking.During tubing pump 13 work, second motor operated valve 9 cuts out.First, second and third water pump row 51,52,53 just start supercharging during tubing pump 13 work, and it is excessive effectively to avoid municipal pipeline pressure to descend like this.
3. adopt the supercharging of partition apparatus water intaking plural parallel stage:
P≤P2, second motor operated valve 9 is opened, and first motor operated valve 4 cuts out, and tubing pump 13 is not worked.City planting ductwork send water through water collect tank emptying to water pump group 5 water inlet ends, and first, second and third water pump row 51,52,53 start supercharging.The rotating speed of first, second and third water pump row 51,52,53 is regulated according to the liquid level of first, second and third anallobar discharge pressure and setting pressure deviation value and water collect tank, level sensor passes to switch board to the liquid level of water collect tank, is regulated the rotating speed of first, second and third water pump row 51,52,53 according to the water collect tank level condition by switch board.If the discharge pressure of three anallobars is lower than pressure of supply water setting value separately, a water collect tank liquid level place high position, first, second and third water pump row 51,52,53 faster rotational speed then, liquid level place low level in the water collect tank, then first, second and third water pump row 51,52,53 rotating speeds slow down, be forced to step-down and supply water, until interrupting water supply.
4. local the utilization surmounts piped water supply:
P 〉=P31, pipe network pressure energy reach first anallobar pressure of supply water setting value, and first motor operated valve 4 is opened, and second motor operated valve 9 cuts out, and 51 dormancy of the first water pump row are directly supplied water to first anallobar by city planting ductwork; At this moment, second and third water pump row 52,53 work, the water that pumps flows to second and third anallobar through second and third anallobar pressure meter 72,73 of correspondence respectively;
If the water pump of upper level anallobar is listed as because of damage or overhauls when not working, pipeline pressure is during less than the next stage pipeline pressure, then the water of next stage anallobar can automatically supply water to the upper level anallobar by the flap valve that surmounts on the pipeline, and only the pressure that supplies water to the upper level anallobar differs and reaches the pressure of supply water setting value surely.This kind mode is interspersed use the in preceding four kinds of mode of operations usually.
Illustrate:
P1: for city planting ductwork intake pressure allows the fluctuation lower limit;
P2: determine by local water supply department for city planting ductwork intake pressure allows the surge limit value;
P31, P32, P33: first, second and third anallobar pressure of supply water setting value (determining) by the user.
P: municipal ductwork pressure.
Relation is between P1, P2, P31, P32, P33:
P2<P1<P31<P32<P33。
