Abstract
A kind of counterpart vacuum motor-pumped well new technology, mainly by pipe screen casing, motor-pumped well, negative-pressure vacuum jar, electric water pump, compositions such as sand water separation tank, flap valve, stop valve form a kind of venting principleand that draws water automatically, be used for quoting underground water source, the device that draws water of well-digging has that power consumption is little, flow is big, automaticity is high, simple in structure, dismounting, easy to maintenance, does not add advantages such as water during starting, extensively the applicable industries water, group unit's living water use, rural area drought resisting water etc.
Description
Common to the general four big kinds of dividing of well-digging: four big classes such as rotary drilling, percussion drilling, sleeve pipe punch, open caisson digs a well.Because these well-digging methods all have a common difficulty, be exactly that layer of gravel and drift sand formation are difficult to construction, generally all need to be pressed into foundry loam with slush pump at gravel, drift sand formation, the gravel drift sand is not flowed, the well-flushing engineering workload of Cheng Jinghou is big, expend increase too, cause the water yield little, a series of unfavorable factors such as expense height.
Use the purpose of technology of the present invention, be to make the water in quicksand and the gravel bed to pass through along speed, also do not need any material G.I.H, make the motor-pumped well cost low, the duration is short.
The method that technology of the present invention is finished is with rig soil layer to be drilled to the specification bore of needs again with a metal tube, (the well casing lower end is according to the size of well casing to reach the good nonmetals pipe of other intensity, bore many apertures in proportion) utilize well-digging equipment to carry out impact endurance test shock to make it to go deep into water table, carry out water flushing again.As the motor-pumped well that machinery draws water, motor-pumped well upper end with the import of negative-pressure vacuum jar be installed link to each other, on the jar drain tap is installed, facilities such as check valve, outlet links to each other with water pump, and the outlet of water pump links to each other with the sand water separation tank, and the knockout drum outlet connects outlet pipe again and arrives millpond.Open vacuum tank earlier when drawing water for the first time and fill water, motor is connected power supply and is rotated, and the water pump that links to each other with motor rotates thereupon and causes the negative-pressure cup vacuum, and the screen casing that is drilled with aperture by the motor-pumped well bottom enters underground water and forms pumping system.After the shutdown, the water back pressure vacuum tank of outlet conduit and cause the drain tap exhaust has so just formed the venting principleand that draws water automatically.
Advantage of the present invention is that power consumption is little, and suction height, flow be degree of changing into height greatly automatically, and is practical wide, simple in structure, easy for assembly, disassembly and maintenance, extensively industrial water use, agglomeration body living water use and rural area drought resisting water.
Accompanying drawing is overall structure figure of the present invention:
The present invention is that the best makes that to execute example be to utilize well-digging equipment, the pipe of the lower end being made screen casing (13) gos deep into water table, and the well head of holding that bassets that becomes the motor-pumped well (12) of well links to each other with negative-pressure cup import (11), on jar flap valve (10) and outlet valve (8) is housed.One side of jar is equipped with delivery port (9) and stop valve (7), the stop valve other end and pump motor (14) are connected, the water pump import is equipped with stop valve (5) the stop valve other end and outlet pipe (4) is housed is connected sand water separation tank import (3), the upper end of jar is delivery port (1), and the lower end is sand removing hole (2).
Claims (5)
1, this counterpart vacuum motor-pumped well new technology comprises that lower end screen casing (13) gos deep into the motor-pumped well (12) of water table; It is characterized in that basset flange and the negative-pressure cup import (11) of end of motor-pumped well fix, the outlet of negative-pressure cup (9) connects with stop valve (7), stop valve and water pump (6) connect, motor (14) is fixed on the pump body, exit of pump is tied mutually with stop valve (5), and the stop valve other end and outlet pipe (4) are fixing, and outlet pipe is bound up on import (3) well water of sand water separation tank and then discharges from the outlet (1) of sand water separation tank, the sand of extracting out is then discharged from sand removing hole (2).
2, counterpart vacuum motor-pumped well new technology according to claim 1 is characterized in that suction pump generally uses centrifugal pump, or selects axial-flow pump for use that pump is direct-connected.
3, counterpart vacuum motor-pumped well new technology according to claim 1 is characterized in that being equipped with negative-pressure vacuum jar and sand water separation tank, forms the exhaust of drawing water automatically.
4, counterpart vacuum motor-pumped well new technology according to claim 1 is characterized in that motor-pumped well pipe generally makes with metal tube, or the pipe of selecting for use plastic pipe and the good nonmetals of other intensity to make.
5, counterpart vacuum machine new technology according to claim 1, it is characterized in that screen casing generally is to bore many apertures in the bottom of motor-pumped well pipe and form, or select the pipe that is more or less the same with the motor-pumped well pipe size for use, the good hole of subdrilling is formed by connecting with motor-pumped well pipe lower end counterpart then.
