Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
Be respectively as marked 1-14 in Fig. 1-2, figure: vacuum pump 1, the house steward 2 that draws water, condensate correcting-distribuing device 3, drinking-water pipe 4, air-pressure tube 5, steam separator 6, tdm controller 7, pneumatics house steward 8, air compressor 9, exhaust tube 10, well lid 11, precipitation pipe well 12, filter opening 13, one way valve 14.
Embodiment 1: as shown in Figure 1, the present embodiment is specifically related to a kind of super pressure and inhales associating pumping system, and this pumping system mainly comprises precipitation pipe well 12, vacuum pump 1 and air compressor 9.
Precipitation pipe well 12 is embedded in underground, and its upper port is basseted a little, and precipitation pipe well 12 needs to be provided with some filter openings 13 or gap, to enter the passage of precipitation pipe well 12 as underground water its pipe shaft differing heights position is spaced apart according to the precipitation of Different Strata; Well lid 11 is connected and sealed with the upper port of precipitation pipe well 12, ensures the operating efficiency of pipe well; Well lid 11 is also reserved with the connected entrance run through for drinking-water pipe 4, air-pressure tube 5 and exhaust tube 10; It should be noted that, in order to ensure the sealing of precipitation pipe well 12, adopting between the top well head of well lid 11 and precipitation pipe well 12 and being tightly connected.
Vacuum pump 1 is positioned on the ground outside precipitation pipe well 12, water-band can be gone out while air-breathing.Vacuum pump 1 is connected with the house steward 2 that draws water, and the house steward 2 that draws water is connected with some drinking-water pipes 4 by condensate correcting-distribuing device 3, to realize being communicated with work with some precipitation pipe wells 12 simultaneously; Each drinking-water pipe 4 to run through on well lid 11 the connected entrance reserved access in corresponding precipitation pipe well 12, the lower end water inlet of drinking-water pipe 4 is positioned at below liquid level near precipitation pipe well 12 basal surface position place; It should be noted that, the lower end water inlet of drinking-water pipe 4 is provided with an one way valve 14, and this one way valve 14, in order to ensure on current direction, avoids the generation of backflow phenomenon.
Air compressor 9 is positioned on the ground outside precipitation pipe well 12, for air feed.Air compressor 9 is connected with pneumatics house steward 8, pneumatics house steward 8 is connected with some air-pressure tubes 5 by steam separator 6, in addition, steam separator 6 is also connected with tdm controller 7, and tdm controller 7 can set service life and the intermittent time of each air-pressure tube 5 according to the height of the diameter of precipitation pipe well 12, pipe well middle water level, the around factor such as transmission coefficient, aquifer character of soil layer; Control steam separator 6 by tdm controller 7, thus it is many that air compressor 9 can be with one, the reasonable distribution working time, makes air compressor 9 reach maximum efficiency; Air-pressure tube 5 to run through on well lid 11 be communicated with drinking-water pipe 4 in the connected entrance access precipitation pipe well 12 reserved, connected entrance is positioned at the top of the lower end water inlet of drinking-water pipe 4, air compressor 9 produce pressure-air and drinking-water pipe 4 in water be mixed to form air-water mixture, thus reduce the proportion of mixture, reduce back pressure, enable underground water increase fast, thus reach the object improving efficiency of drawing water.
In addition, the well lid 11 of precipitation pipe well 12 is also provided with an exhaust tube 10, protrudes from the soffit of well lid 11 downwards in the lower port of this exhaust tube 10 access precipitation pipe well 12, its upper end to be positioned at outside precipitation pipe well 12 and to be connected with drinking-water pipe 4.
As shown in Figure 1, in the present embodiment, the method for work of super pressure suction associating pumping system is:
(1) when tdm controller 7 control air-pressure tube 5 adopt intermittent gas supply time, in intermittent periods, air in exhaust tube 10 pairs of precipitation pipe wells 12 vacuumizes, the water surface in precipitation pipe well 12 is made to form negative pressure, be flowed to endlessly in precipitation pipe well 12 with the underground water accelerated in precipitation pipe well 12 surrounding formation (stratum that especially permeability is little), thus improve the water collection efficiency of precipitation pipe well 12; Meanwhile, drinking-water pipe 4 to draw water operation to the underground water in precipitation pipe well 12 under the driving of vacuum pump 1;
(2) when tdm controller 7 control air-pressure tube 5 carry out air feed time, the pressure-air that air compressor 9 produces is sent in drinking-water pipe 4 through air-pressure tube 5, the water taken out with drinking-water pipe 4 is mixed to form air-water mixture, thus reduce the proportion of mixture, reduce back pressure, enable underground water increase fast in drinking-water pipe 4, thus improve the efficiency of drawing water of pumping system.
The beneficial effect of the present embodiment is: vacuumize while taking out precipitation, and vacuum is high than existing methods, and the pumpdown time is long, and precipitation pipe well water collection efficiency can improve about 10%; Adopt timesharing air feed control system, be both conducive to improving vacuum in precipitation pipe well, and air compressor can also have been reduced to initial air pressure requirement, make separate unit air compressor machine can drive more precipitation pipe well; Adopt air compressor to provide pressure-air, not only can improve precipitation pipe well internal gas pressure, can also form air-water mixture to reduce proportion, to reduce back pressure with the water in drinking-water pipe, thus improve pressure differential, efficiency of drawing water comparatively conventional method can improve more than 50%; A set of pumping system in the present embodiment can drive 6-12 mouth precipitation pipe well simultaneously, compared with conventional method, saves the input of a large amount of submersible pump equipment, cost-saving more than 50%; Plant equipment is all placed in outside well, installs border, is easy to operation, easy access and maintenance, and the application life extending equipment; This pumping system is applied widely, applicable equally more containing silt in water, water proportion is larger.
Embodiment 2: as shown in Figure 2, the present embodiment is specifically related to a kind of super pressure and inhales associating pumping system, in this pumping system and embodiment 1, the difference of pumping system is that air-pressure tube 5 and drinking-water pipe 4 adopt the concentric mode arranged, be specially: outside precipitation pipe well 12, air-pressure tube 5 and drinking-water pipe 4 are connected and stretch among drinking-water pipe 4, both are coaxial is arranged, the lower port of air-pressure tube 5 stretches to one way valve 14 position near drinking-water pipe 4, it should be noted that, air-pressure tube 5 stretches into depth adjustable in drinking-water pipe 4.
When pumping system works, according to the result circumferentially descending water level observation well to observe, the built-in length of air-pressure tube 4 can be adjusted at any time, to change the position of air-pressure tube 4 lower port, avoid water-head excessive and increase the initial pressure of air compressor 9, thus improving effect.
In this enforcement, all the other structures of pumping system and method for work are all same as described in embodiment 1, do not repeat them here.
