Abstract
The utility model relates to a double-airbag pneumatic sampling pump, which is characterized in that two water-storing cavities and two air inlet bags are arranged in the pump body. A clapboard longitudinally arranged in the pump body partitions the pump body into the two water-storing cavities, wherein, lower check ball valves and upper check ball valves are respectively arranged on lower and upper ends in the two water-storing cavities, in which the two air inlet bags are arranged, and the upper ends of the two air inlet bags are respectively connected with air inlet pipes. When the utility model is used, after the bulk of the two air inlet bags in the pipe of the pump body is inflated or deflated by alternate charging, the bulk of the two water-storing cavities is inflated or deflated as well, and under the alternate function of a unidirectional check valve, the water in the two water-storing cavities is alternately and continuously discharged out of the pump. Meeting the using requirements of spots, the utility model has the advantages of high working efficiency, large sampling water flow, long service life, simple structure and convenient maintenance.
Description
Technical field
The utility model relates to the geologic prospecting equipment technical field, is a kind of pair of pneumatic sampling pump of air bag, and the underground water sample that is mainly used in the groundwater pollution fact-finding process is taked, and also can be used for small-bore well and draws water.
Background technique
Taking representative underground water water sample in the hole is the indispensable important process of groundwater pollution investigation.Sampling pump is to carry out the topmost equipment of underground water sampling work.The monosaccate sampling pump is one of present used underground water sampling pump, and this pump is made up of the pump housing and the outlet pipe, the high-pressure air pipe that are attached thereto.Be provided with in the pump housing: one in air bag, each one of upper and lower check valve.During sampling, the pump housing needed the degree of depth of sampling in the hole, under the effect of hydrostatic pressure, check valve is opened under the pump housing, water in the hole enters water storage cavity, sends into pressurized air by the high-pressure air pipe that is connected with the pump housing and makes air bag produce expansion, when air bag produces expansion, the last check valve of water storage cavity is opened, and following check valve cuts out.Because the water in the airbag inflation, water storage cavity is pressed in the outlet pipe.Stop air feed, last check valve cuts out immediately, and following check valve is opened under hydraulic action, and air bag shrinks, and water enters in the water storage cavity again.Behind the air feed, the water of water storage cavity is pressed in the outlet pipe again.So repeatedly, the water in the hole drains into from outlet pipe in the water sample trap on the face of land, realizes taking of underground water water sample.
Owing to have only an air bag in the pump housing of monosaccate sampling pump, cause that water outlet is discontinuous, sampling efficiency is low, sampling flow is little.
The model utility content
The purpose of this utility model provides the pneumatic sampling pump of two air bags that a kind of volume is little, weight is low, current are steady, sampling efficiency is high, sampling flow is big, lift is high.
For achieving the above object, the utility model is taked following design proposal:
A kind of pair of pneumatic sampling pump of air bag is characterized in that: have two water storage cavities and two air inlet capsules in the pump housing.
In the pump housing, be vertically arranged with a dividing plate, this dividing plate will be separated into two water storage cavities in the pump housing, lower end in two water storage cavities and upper end are respectively arranged with check ball valve and last check ball valve down, are provided with two air bags in two water storage cavities, are connected with suction tude respectively in the upper end of two air bags.
This pair of pneumatic sampling pump working principle of air bag is: by alternately inflating expansion and the contraction that changes two air bag volumes in the pump housing pipe, force two water storage cavity volumes to change thereupon, under the check ball valve alternating action, the water in two water storage cavities is alternately continuously outside the excavationg pump.The pneumatic sampling pump of two air bags is a variable displacement pump that determines water yield size along with air supply source alternate speed.
This pair of pneumatic sampling pump of air bag has routine advantage down:
When 1, the pneumatic sampling pump of this pair air bag is gathered water sample, after the pneumatic sampling pump pump housing of two air bags slips into and adopts water layer water by compressing into pump housing water storage cavity, then external by the balloon tamponade excavationg pump again.At this moment gathering water sample does not have mechanical high-speed to stir and quick suction movement, and gas does not contact with the water sample of being gathered, the air free water mixing phenomena, so can not cause the acquisition zone waters that very big fluctuation is arranged, can not cause the secondary pollution of gathering water sample, the water sample of extraction to keep substantially yet by waters, exploiting field characteristic.
2, the pneumatic sampling pump water lift of this pair air bag mechanism is to rely on volume behind the airbag aeration to become to force pump housing inner storing water chamber volume to diminish greatly the water excavationg pump that forces water storage cavity external.Can think that in theory the Yang Cheng of this pump and pressure are proportional.This couple of pneumatic sampling pump design pressure of air bag 1.6Mpa, Yang Chengke reach 160 meters.
3, the alternate proportional (within the specific limits) of the pneumatic sampling pump flow of this pair air bag and two air bags, alternating frequency is fast more in other words, flow is also just big.The pneumatic sampling pump flow of two air bags can reach 20 liters/min.
4, the pneumatic sampling pump compact structure of this pair air bag volume is little, 76 millimeters of pump housing external diameter diameters, and pump housing gross weight in light weight is no more than 5 kilograms.Can adapt to the sampling of conventional hole diameter.
5, do not have high speed rotary motion in the pneumatic sampling pump pump of this pair air bag, do not have wearout parts, can not cause component wear, long service life, simple in structure, easy to maintenance.
