Description
1, technical field
The utility model relates to a kind of supply equipment, a specifically a kind of self-balancing gas compensating type high position that is connected in series on the pipe network direct supply equipment of regulating and storing.
2, background technology
The supply equipment of prior art has two big classes, one class is the water pump pressurization of fetching water from pond, water tank, to avoid water pump directly to be connected in series the effect of supplying water and having certain water yield of regulating and storing, be indirect feed equipment, such supply equipment because of be provided with pond, water tank make its take up an area of big, investment is high, can not utilize ductwork pressure, operation is not energy-conservation, but also has problem such as water pollution; Another kind of is the direct-type supply equipment, be on the basis of water inlet pipe pressure, to adopt water pump to laminate water supply, can utilize the original pressure of pipe network, but when water inlet pipe pressure is lower than minimum setting pressure with regard to termination of pumping, cut off the water supply, and adaptive system also can cause discharge pressure fluctuation etc. at the energy-saving run of low discharge when water pump platform number increases, subtracts in the process well.
3, utility model content
In view of above-mentioned the deficiencies in the prior art, the utility model provides a kind of energy saving in running, the self-balancing gas compensating type high position stable, intake pressure also can connect water supply when low that supplies water is regulated and stored direct supply equipment.
The technical scheme that its technical problem that solves the utility model adopts is: a self-balancing gas compensating type high position direct supply equipment of regulating and storing is by non-negative pressure stabilized jar, air supply tank, control valve, transfer valve, water pump, switch board and air pressure are regulated and stored jar and to be formed, installing stationary barrier in non-negative pressure stabilized jar, and non-negative pressure stabilized jar is divided into plenum chamber and conditioning chamber two parts, plenum chamber is connected with water inlet pipe, and on water inlet pipe, be provided with strainer and backflow preventer, on plenum chamber, also be provided with inlet pressure detection table, the plenum chamber water outlet is received water pump through pipeline, and walk around water pump and be provided with bypass pipe, on bypass pipe, be provided with flap valve and valve in turn along water (flow) direction, and between flap valve and valve, adopt liaison tube to be connected to conditioning chamber, transfer valve is housed on the liaison tube, at conditioning chamber top installing air supply tank, and between conditioning chamber and air supply tank, be provided with control valve, the air supply tank top is provided with air filter and gas stoper, be provided with level switch in the conditioning chamber, plenum chamber and conditioning chamber bottom are equipped with draining valve, on outfall sewer, be provided with outlet pressure detection table, outfall sewer is connected with the water pipe network, and with the water spot place air pressure jar of regulating and storing is set at the least favorable of water pipe network, the air pressure jar inside of regulating and storing is provided with diaphragm of rubber, and respectively be provided with pressure meter, inlet pressure detects table, control valve, transfer valve, water pump, outlet pressure detection table is wired to switch board respectively, and is provided with the modular converter of water-aspirator pressure control in the switch board.
During operation, current directly enter non-negative pressure stabilized jar plenum chamber after passing through filter, backflow preventer by water inlet pipe, supply water by the water pump pressurization again, water pump detects table by outlet pressure and realizes constant pressure water supply, this moment transfer valve open, control valve closes, when the inflow of water inlet pipe during greater than the water yield of outfall sewer, water pump will regulate and store for jointly water pipe network, non-negative pressure stabilized jar conditioning chamber and least favorable and jar supply water with the air pressure at water spot place, the diaphragm of rubber expansion that air compression in the conditioning chamber and air pressure are regulated and stored jar, and store a part of regulating pondage separately; When the inflow of water inlet pipe water yield less than outfall sewer, when situations such as water pump platform number increases, subtracts, pressure oscillation perhaps in running, occurring, regulating pondage in conditioning chamber and air pressure are regulated and stored jar will in time replenish, influence with the negative pressure of eliminating the inflow deficiency, and adjustable throttle quantitative changeization and stable ductwork pressure; Air pressure was regulated and stored jar at night during the low discharge water, by detecting the operation condition of water pump low frequency, by the termination of pumping of predefined programme-control water pump, and regulate and store jar by air pressure and to supply water, the regulating pondage of regulating and storing jar when air pressure reduces, the pressure of outlet pressure detection table is lower than setting when opening pump pressure, water pump starts and automatically to the air pressure jar moisturizing of regulating and storing, and is so multiple past, to realize the energy-saving effect of low discharge operation; Reduce when the inflow of water inlet pipe is lasting, when causing the force value of inlet pressure detection table to be lower than the minimal protection pressure of its setting, the minimal protection pressure operation that modular converter in the switch board will make water pump set according to inlet pressure detection table, make water inlet pipe pressure be not less than the minimal protection force value of this setting, thereby avoided the negative pressure influence of water inlet pipe because of the inflow deficiency guaranteed to supply water incessantly simultaneously; When the water that can satisfy the water pipe network when water inlet pipe pressure requires, the water pump pump trip, directly supplied water by bypass pipe this moment.
Because the air in the conditioning chamber directly contacts with water, the water-soluble meeting of air reduces the air in the conditioning chamber gradually, water level in the conditioning chamber when pump working will rise, regulating pondage in the conditioning chamber reduces, when the water level in the conditioning chamber surpasses the highest design water level of level switch, transfer valve cuts out, control valve is opened, carry out the self-balancing tonifying Qi by air supply tank by control valve this moment, outside air sucks air supply tank, and,, the air in the conditioning chamber is increased through self-balancing tonifying Qi repeatedly to the conditioning chamber tonifying Qi, drawdown, water level in conditioning chamber is lower than the highest design water level of level switch when following, control valve is closed, and transfer valve is opened, and system returns to the normal water supply state.
The beneficial effects of the utility model are, non-negative pressure stabilized jar is divided into plenum chamber and conditioning chamber, and conditioning chamber adopts the self-balancing tonifying Qi, makes to keep the normal regulating water yield, guarantee that the instantaneous delivery that does not have negative pressure regulates; With the water spot place air pressure jar of regulating and storing is set at least favorable, not only can regulates flow, stablize ductwork pressure and realize that low discharge supplies water, reaching the effect of stable and energy saving in running that supplies water, but also can increase the volume adjusted of system, saved investment and materials; In addition, pump interrupted water ground is supplied water, and water inlet pipe is not produced negative pressure, so also improved reliability of water supply etc.
