Description
Technical field
The utility model relates to a kind of piston pump, belongs to the mining equipment field.
Background technique
Emulsion pump is for coal-face, and for hydraulic support provides emulsified liquid, working principle is to lean on the piston that rotarily drives of bent axle to move reciprocatingly, and realizes imbibition and discharge opeing process.Emulsion pump is widely used under coal mine, for hydraulic support provides hydraulic transmission medium, makes hydraulic support that enough support forces be arranged on the one hand, can make on the other hand hydraulic support keep lubricated, keeps the cylinder interior non-corrosive.
Emulsified liquid is that water and the oil by the certain volume ratio mixes, and emulsified liquid used is generally by special-purpose emulsified liquid automatic preparation equipment preparation at present.Emulsified liquid after preparation is stored in casing, when hydraulic support needs, by emulsion pump, is drawn, and then by the pipeline high pressure, transfers to hydraulic support.The emulsified liquid that water and oil form is transported to two kinds of equipment of this process need of hydraulic support and sequentially completes: the one, and emulsified liquid dosing apparatus, the 2nd, emulsion pump.These two kinds of equipment not only take more mine space, and need more economic input; In addition, emulsified liquid long-term placement in container also can be gone bad; Therefore, current emulsified liquid dosing apparatus and emulsion pump can not well meet the need of production in colliery.
The model utility content
The problem existed for above-mentioned prior art, the utility model provides a kind of piston pump, can automatically configure at any time emulsified liquid, reduces taking, effectively the preventing emulsified liquid in mining space and places for a long time and go bad.
To achieve these goals, the technical solution adopted in the utility model is: a kind of piston pump, comprise motor, coupling, retarder, bent axle, connecting rod, the pump housing, piston and piston cavity, motor output shaft is by coupling connection reducer input shaft, the rotation of reducer output shaft driving crank, bent axle connects connecting rod makes piston do linear reciprocating motion in piston cavity, and piston and piston cavity are arranged in the pump housing; Also comprise plunger, plunger cavity, water suction changeover valve group, draining changeover valve group, oil suction changeover valve group, oil extraction changeover valve group, oil-water mixer, fuel tank and water tank; The structure that described plunger and piston are integral type, piston cavity communicates with fuel tank by oil suction changeover valve group, and plunger cavity communicates with water tank by water suction changeover valve group; Piston cavity, plunger cavity communicate with oil-water mixer by oil extraction changeover valve group, draining changeover valve group respectively, and the effective active area of piston and plunger is 5:3.
The number of piston is 3-5.
The fuel-tank outlet place is provided with throttle valve.
With existing apparatus, compare, the utility model changes the emulsion pump piston structure into piston and adds piston structure, and piston and plunger effective active area be 5:3, will draw or discharge water and the oil of certain volume ratio, forms certain density emulsified liquid; This emulsion pump, except having High voltage output emulsified liquid function, also has emulsified liquid automatic preparation function, thereby significantly reduces taking of economic input and mine space; Can prepare at any time in the needs emulsified liquid on the other hand, without separately using the container storage emulsified liquid, thereby effectively prevent long-term placement of emulsified liquid and go bad.
