Abstract
The utility model relates to a centrifugal sand and stone water pump positive and negative circulation device. The utility model is characterized in that a positive-circulation structure and a negative-circulation structure are organically connected with each other via a water pump, a valve and a pipeline, and the negative-circulation actions and the negative-circulation actions of the centrifugal sand and stone water pump positive and negative circulation device are under the control of the main parts, wherein, the main parts comprise a magma-discharging gate valve, a magma-discharging pipeline, a positive-pressure gate valve, a water-absorbing gate valve, a water-supplying gate valve, a three-way pipeline, etc. The device has the advantages of compact structure, convenient operation, high magma-discharging ability, and high drilling efficiency, and can drill at any time without stopping the pump to connect with a drill rod.
Description
The utility model belongs to the mechanical device with the matching used sandstone water pump of drilling well rig, is specially adapted to the supporting use of shallow-layer well drilling-in unit.
Before the utility model, the matching used centrifugal sandstone water pump of traditional hobo rig mostly is centrifugal direct circulation formula, and centrifugal direct circulation is along with the increase of well depth, pressure increases thereupon, and the water yield reduces, down-hole rock dust content increases, and the drill bit running resistance increases, and influences drilling efficiency.But the employing that also has is centrifugal anti-circulating, adopt anti-circulation in drilling rod, to extract the rock dust particle, residue rock dust slurry is less in the wellhole, drill bit is little at the wellhole internal resistance, anti-circulation can be stabilized in certain drilling rod altitude range, change in depth is little to the influence of pump, therefore the anti-progress that circulates in the drilling process is very fast, but anti-periodic duty pump need be provided with auxilliary genus equipment vacuum pump, inhales vacuum and charging pump equipment and could work, whenever connecing a drilling rod just needs to inhale a vacuum or starts the starting operation of a water ability of water-filling pump pressure, not only equipment dynamic is many, and the trivial operations program is many, so the driller wishes to have a kind of device can have just reverse circulating function concurrently always.
The purpose of this utility model is to overcome the deficiency of the supporting centrifugal sandstone water pump direct circulation formula of rig, with overcome the many shortcomings of the anti-auxiliary equipment that circulates of the centrifugal sandstone water pump of rig, a kind of positive and negative circulating device of centrifugal sandstone water pump that has positive and negative circular centrifugal sandstone water pump advantage simultaneously concurrently is provided, make it to have just reverse circulating function, reach the purpose of dual-use, at scall, gravel layer creeps into and can adopt anti-circulation, but when running into argillic horizon direct circulation pulping guard aperture, or take place to adopt the direct circulation rollback when card blocks up the drilling rod accident, the positive and negative circulating device of this centrifugal sandstone water pump that provides has compact conformation, easy and simple to handle, the plasma discharge ability is strong, save non-cutting time, improve start efficient.
The utility model is achieved in that the positive and negative circulating device of centrifugal sandstone water pump is made up of critical pieces such as centrifugal sandstone water pump, valve, pipelines, be positioned at centrifugal sandstone water pump one side above threeway is set, one end of threeway is provided with pulp-expelling valve by pipeline, pulp-expelling valve connects the plasma discharge pipeline, the other end of threeway is provided with the malleation gate valve by pipeline, and the malleation gate valve connects the malleation pipeline.A side right side that is positioned at centrifugal sandstone water pump is provided with the suction threeway, one end of suction threeway is provided with the suction gate valve, the suction gate valve connects water supply pipeline, water supply pipeline is communicated with the malleation pipeline, the other end of suction threeway connects the water supply gate valve, the water supply gate valve connects sewer pipe, and sewer pipe connects the suction tap.When implementing reverse circulation drilling, water supply gate valve and malleation gate valve are closed, open suction gate valve and plasma discharge gate valve, pump can be finished positive and negative cyclical-transformation at any time in normal operation, and pump is drawn shaft bottom rock Xiao by drilling rod and is entered sedimentation basin, flows into boring then naturally.Move in circles like this and just formed anti-circulation; When implementing the direct circulation operation, close without will absorb water gate valve and plasma discharge gate valve of termination of pumping, open water supply gate valve and malleation gate valve, water pump is drawn the water in pond by the sewer pipe water tap like this, send in the drilling rod by the malleation pipeline, at the bottom of via hole, take for rock dust and return out the aperture then, flow into the pond and so just formed direct circulation.
The utility model has reached design purpose, this device has the function that anti-circulation and direct circulation are had both, at scall, gravel layer creeps into and can adopt anti-circulation, but when running into argillic horizon direct circulation pulping guard aperture, perhaps take place to block when blocking up the drilling rod accident, can adopt the direct circulation rollback, with saved equipment in the traditional employing reverse circulation drilling process, saved vacuum pump and water pump, this device also has compact conformation, the strong advantage of plasma discharge ability easy and simple to handle, without the termination of pumping stacks, saved non-cutting time, improved driving efficient; This device is specially adapted to 200 meters of well depths with interior operation, particularly at hundred meters with interior shallow well drilling construction best results.
Further describe in conjunction with the accompanying drawings:
