Description
Technical field
The utility model relates to the homemade well hydrotechny, but a kind of deep well pump frequency-changing pressure stabilizing pressure-stabilizing water supply system that realizes homemade well power-saving running when low discharge supplies water particularly.
Background technology
Development along with variable-frequency control technique, deep well, homemade well adopt the very extensive of varying speed and constant pressure feed water technology, and the human livestock drinking water engineering that especially current country supports and the considerable system of central water supply engineering of new countryside construction have adopted deep well variable frequency water supply pattern.But frequency-conversion water supply system " takes " on the contrary if type selecting and control does not improperly not only reach energy-conservation purpose in actual applications, and especially deep well frequency-conversion water supply system problem is particularly outstanding.Many villages and small towns or homemade well user are after adopting the variable frequency water supply pattern for this reason; feel and unlike " just economizing on electricity with frequency conversion " of tradition publicity; some villages and small towns is difficult to bear because the electric lighting bill is heavy; make the variable frequency water supply technology is produced " suspection " and " trust crisis ", even some local human livestock drinking water project does not simply adopt the variable frequency water supply pattern.
The basic reason that produces these problems is the low discharge energy consumption problem that frequency-conversion water supply system exists.Generally when pump speed control 70% is following, pump efficiency sharply reduces, and actual water system is not open loop situations, but the constant voltage closed-loop control system, because " water blockage " phenomenon, the speed adjustable range of water pump can not be very big, otherwise just do not satisfy the requirement of setting pressure, so pump rotary speed and not really low when actual frequency-changing pressure stabilizing closed loop water system low discharge even " zero delivery ", the pipeline setting pressure is more high, and " zero delivery " frequency is more high.Rule of thumb, multilayer frequency-conversion water supply system " zero delivery " frequency is about 25 ~ 35Hz, high-rise, deep well water system " zero delivery " frequency are about 30 ~ 40Hz, if the rich amount of pump head is little, " zero delivery " frequency also can be bigger.Along with growth in the living standard, general domestic water supplying system all requires 24h uninterruptedly to supply water, and for pure domestic water supplying system, the water supply peak mainly concentrates on morning, noon and afternoon three about 8h of period, all the other time outputs are very little, if pump power is bigger, although employing frequency converter timing, but because adjustable speed water pump operational efficiency under low discharge is very low, thereby cause and wasted very big electric energy in the low discharge water supply time section, general submersible pump power is all bigger, thereby deep well frequency conversion system low discharge " waste " problem is more outstanding.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of deep well pump frequency-changing pressure stabilizing pressure-stabilizing water supply system, to solve existing deep well pump constant pressure water supply system at the low discharge low technical barrier with waste of energy of period deep well pump operational efficiency that supplies water.

The specific embodiment
Be further described below in conjunction with the utility model of embodiment:
As shown in Figure 1, the utility model mainly is made up of deep well pump 1, lifting pipe 2, flap valve 3, water meter 4, total gate valve 5, frequency conversion tank 11 etc., the lifting pipe 2 of deep well pump 1 connects the water main, frequency conversion tank 11 links to each other through water-fast diving cable 12 with deep well pump 1, be provided with flap valve 3, water meter 4 and total gate valve 5 on the water main successively, water main between flap valve 3 and water meter 4 is equipped with the low discharge capsule type air-pressure jar 9 of bumper and absorbing shock and low discharge regulatory function, and capsule type air-pressure jar 9 is connected with the water main by gate valve 10.
The specification of capsule type air-pressure jar 9 is selected according to specified output or water supply amount, general its nominal diameter is between DN600 ~ DN2500, the rubber bag tank of health level is installed in capsule type air-pressure jar 9 tank bodies, tank body top is reserved with the valve of pre-inflation usefulness, according to the specified pressure of supply water of system, the pre-the blowing pressure of capsule type air-pressure jar 9 generally approaches or is lower than specified setting pressure slightly.
