Description
Technical field
The utility model relates to water system, specifically a kind of supercharging current stabilization water system.
Background technology
At present the urban groundwater position is more and more lower, and therefore, a lot of industrial water uses have to supply water via reservoir, because reservoir comes water to be generally the constant voltage quantitative water supply, and water Fang Ze is according to condition of production difference, and institute's water supply volume is non-constant.Therefore, in the prior art, generally be to build the reservoir retaining, pressurization is supplied water according to water side's conditions of demand again, uses needs to satisfy.Though this way of supplying water can be realized constant-pressure variable and supply water, but owing to need build reservoir and pumping plant, not only floor space is big, difficulty of construction is big, the cycle is long, investment is big, and there are run, drip, leak in traditional reservoir, ooze phenomenon, therefore can cause invalid water yield loss, causes the waste of the energy owing to reservoir comes water pressure not to be utilized effectively in addition.
The utility model content
The purpose of this utility model will provide a kind of floor space little exactly, convenience quick for installation, short construction period and can economize on water, energy-conservation a kind of supercharging current stabilization water system.
The utility model is achieved in that this supercharging current stabilization water system is made up of the buffering steady flow compensator and the constant-pressure variable frequency conversion deep well pump of parallel connection; Be provided with liquid level emasuring device and device for pressure measurement in the buffering steady flow compensator, the buffering steady flow compensator is provided with water inlet pipe, outlet pipe and drain valve, establishes aeration valve, outlet valve, safety valve at its top; Be provided with force (forcing) pump on outlet pipe, the outlet pipe of force (forcing) pump and constant-pressure variable frequency conversion deep well pump outlet pipe also meet the composition water main; Liquid level emasuring device, device for pressure measurement, safety valve, drain valve and force (forcing) pump and the constant-pressure variable frequency conversion deep well pump of buffering steady flow compensator are electrically connected with the PLC Centralized Controller.
Supercharging current stabilization water system of the present utility model is made up of the buffering steady flow compensator and the constant-pressure variable frequency conversion deep well pump of parallel connection, the water that comes of external constant voltage constant enters the buffering steady flow compensator, and water outlet obtains the required pressure in water side after the force (forcing) pump supercharging constant supplies water.The adjustment of force (forcing) pump discharge pressure is required to control by the water of PLC Centralized Controller according to water side.The transformation constant feed pipe that the feed pipe of frequency conversion deep well pump and aforementioned force (forcing) pump provide also meets the composition water main.Deep well pump is the variable frequency pump of constant-pressure variable, and the trend that water main's pressure that can cause according to the situation that water side's water supply volume changes changes is adjusted the electric machine frequency of deep well pump by the PLC Centralized Controller, thereby adjusts the output of frequency conversion deep well pump.But this part constant-pressure variable supplies water and through the pressure control constant of force (forcing) pump pressurization come water to mix after, can realize providing the constant-pressure variable that is fit to the user demand of water side to supply water according to the water supply volume situation of change of water side.This water system makes full use of water pressure, only the pressure reduction that comes the required pressure in water pressure and water side is carried out ftercompction, therefore, compares with traditional complete again pressing mode of water pressure release of coming, and can economize on electricity 30%.And, because the construction of having saved reservoir and pumping plant, make that to the utlity model has investment little, corresponding beneficial effect such as easy construction.
Because force (forcing) pump adopts the Frequency Converter Control water pump to supply water, thereby guarantee that the force (forcing) pump flow is a definite value, therefore can be, and cause reservoir to come the waterpipe internal pressure to produce fluctuation and to coming waterpipe to cause brokenly ring because of the variation of plant area's water supply volume, thus can effectively guarantee waterpipe and system safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, this supercharging current stabilization water system is made up of the buffering steady flow compensator 5 and the constant-pressure variable frequency conversion deep well pump 2 of parallel connection.Expansion loop belongs to pressure vessel, and content gauge 4 and on-the-spot pressure meter 8 are housed.Expansion loop 5 is provided with water inlet pipe 12, outlet pipe 13 and drain valve 10, establishes aeration valve 6, outlet valve 7 and safety valve 9 at the expansion loop top.
According to coming water water pipe quantity, buffering steady flow compensator 5 can be one, also can be arranged in parallel simultaneously two or more than, present embodiment is that two buffering steady flow compensator are arranged in parallel.Reservoir through two line transportation comes water, respectively through water inlet pipe 12 input buffering steady flow compensator 5.On outlet pipe 13, be provided with force (forcing) pump 3, by can obtaining the water supply of the required pressure in water side to the adjusting of force (forcing) pump, this part supply water with 2 water outlets of constant-pressure variable frequency conversion deep well pump and connect and form water main 14.Fluviograph 4, on-the-spot pressure meter 8, safety valve 9, drain valve 10 and force (forcing) pump 3 and the constant-pressure variable frequency conversion deep well pump 2 of buffering steady flow compensator 5 are electrically connected with PLC Centralized Controller 1.Water level in the expansion loop 5 preestablishes lowest working water level, peak level and lowest water level.When water level arrived each limiting value, system sent alarm signal, simultaneously, and when water level arrives lowest water level, by the chain termination of pumping of PLC Centralized Controller 1 control.
When expansion loop 5 internal pressures when coming water pressure and pressure reduction to surpass preset value, aeration valve 6 is opened, tonifying Qi in expansion loop 5.When the expansion loop internal pressure when coming water pressure to equate, close aeration valve, stop tonifying Qi.When expansion loop 5 internal pressures when coming water pressure, safety valve 9 is opened to reduce the expansion loop internal pressure.When the expansion loop internal pressure when coming water pressure and pressure reduction to surpass preset value, outlet valve 7 is opened exhaust.After safety valve was opened, water level rose to when exceeding peak level to a certain setting value in jar, and the drain valve 10 on the expansion loop 5 is opened sluicing, and drawdown is closed to late gate to a certain degree.
For guaranteeing the safety of water lines, a kind of embodiment preferably is to be equipped with on the water lines to hold and press relief valve 11 what join with buffering steady flow compensator water inlet pipe mouth, when coming water pressure to surpass preset value, holds and presses relief valve 11 to open the draining pressure release.
The utility model whole system is controlled to be the PLC centralized Control, but all move all centralized displaying of water yields, hydraulic pressure, water temperature, liquid level, and various interlockings are controlled automatically by PLC, and establishes liquid level, the warning of pressure superelevation.
