But find in the practical application, also there is some problems in this water supply scheme, keep off the period (for example actual water supply is greater than the water supply period more than 10% of metered flow) of " zero delivery " in the system water supply amount, the frequent start-stop of deep well pump, cause overall ton water power to consume the water tower water-feeding pattern difference of comparing still larger, the low discharge capsule type air-pressure tank specification that configures in the system is less, and the deep well pump start-stop is more frequent, and average ton water power consumption is larger.The user who for this reason has is for further reducing ton water power consumption, change or increase the capsule type air-pressure tank of larger specification, but actual ton water power consumption reduces very unobvious, this mainly is because the operating pressure ratio α of capsule type air-pressure tank is larger in the common homemade well frequency-conversion water supply system, therefore the adjustable capacity of capsule type air-pressure tank is less than 1/10 of its rated capacity, and for example the capsule type air-pressure tank pondage reality of DN1000 * 2500-1.0 approximately only has 0.1m
3So frequent in low discharge water supply period deep well pump start-stop, ton water power consumption is still higher.
