Abstract
Disclosed is a light emulsifying fluid pump station which is applied in anchor bar supporting active face fore sets for tunneling. The utility model aims to operate simply, move conveniently, integrate preparation of the oil emulsion and supply high pressure of the oil emulsion. The utility model comprises an electric motor, a wedge shaped belt, a continuously speed change gear, a cycloid oil-absorbing pump, an emulsified oil basin, a water cutoff valve, a water pressure reducing valve, an one-way valve, a filter, a high pressure plunger pump, a manometer and an escape valve. The electric motor connects with the continuously speed change gear through an actuating device and then connects with the cycloid oil-absorbing pump through a clutch; The electric motor connects with the high pressure plunger pump through the clutch; the oil-absorbing port of the cycloid oil-absorbing pump connects with the emulsified oil basin, the oil-out connects with the pressure reducing valve outlet though the one-way valve at the entrance of the filter, the outlet of the filter connects with the entrance of the high pressure plunger pump, the manometer and the escape valve are connected together at the outlet of the high pressure plunger pump.
Description
Technical field
The utility model relates to a kind of emulsion power pack that pressure emulsified liquid is provided.
Background technique
The emulsion power pack that uses on the present colliery; general all is complicated fixed pumping plant; mainly comprise emulsion pump group, case group and necessary control, protection and supervision element; this pumping plant only provides high-pressure emulsion to fully mechanized mining face hydraulic prop and support, and the preparation of emulsified liquid also needs to use in addition other devices.At digging laneway during with suspension roof support working surface foreset, because of the fluid pressure and the flow of needs is not very big, use not only troublesome poeration of this pumping plant, and waste.
Summary of the invention
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, a kind of simple to operate, conveniently moving is provided, integrates emulsified liquid preparation and the light-duty emulsion power pack that high-pressure emulsion is provided.
The utility model comprises motor, belt driver, stepless speed variator, cycloid formula oil scavenge pump, emulsion tank, water stop valve, water reduction valve, one-way valve, filter, high-pressure plunger pump, pressure meter and safety valve.Motor links to each other with stepless speed variator through belt driver, is connected with cycloid formula oil scavenge pump through coupling again; Motor also links to each other with high-pressure plunger pump through coupling simultaneously; The inlet port of cycloid formula oil scavenge pump is connected with emulsion tank, and oil outlet is through exporting and be connected on the inlet of filter with the water reduction valve behind the one-way valve; The outlet of filter links to each other with the inlet of high-pressure plunger pump, and pressure meter, safety valve are attempted by the outlet end of high-pressure plunger pump.
Motor is drawn oil emulsion through belt driver and stepless speed variator driving oil scavenge pump from emulsion tank, pressure water source mixes at the filter inlet place with oil emulsion through the water reduction valve, discharge from the outlet of filter through forming certain density, uniform and stable emulsified liquid behind the filter, enter high-pressure plunger pump then, what discharge is exactly to have emulsified liquid certain pressure, accurate concentration again.Pressure meter and safety valve are connected on the outlet port of high-pressure plunger pump, regulate the emulsified liquid that safety valve just can obtain required pressure, can see force value intuitively by pressure meter.Turn off the water stop valve, cut off the electricity supply, light-duty emulsion power pack promptly quits work.
The utility model mainly is applicable to digging laneway suspension roof support working surface foreset, also can be used for the stope and the hydraulic prop repair shop of small coal mine.Simple to operate, the conveniently moving of the utility model integrates the emulsified liquid preparation and high-pressure emulsion is provided, and saves time and manpower.Can provide the high-pressure emulsion of accurate concentration immediately, and concentration and pressure are all adjustable continuously.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model hydraulic schematic diagram.
Among the figure, 1. motor, 2. coupling, 3. belt driver, 4. stepless speed variator, 5. coupling, 6. cycloid formula oil scavenge pump, 7. emulsion tank, 8. one-way valve, 9. filter, 10. high-pressure plunger pump, 11. the water reduction valve, 12. water stop valves, 13. pressure meters, 14. safety valves, 15. one-way valves.
Embodiment
Motor 1 drives stepless speed variator 4 by coupling 2, belt driver 3, after stepless speed variator 4 slows down, drive cycloid formula oil scavenge pump 6 by coupling 5 again and draw oil emulsion from emulsion tank 7, oil emulsion converges in the ingress of filter 9 with the pressure clear water that passes through water stop valve 12 and water reduction valve 11 behind one-way valve 8, behind filter 9, just obtain certain density emulsified liquid.And then enter the high-pressure plunger pump 10 that drives simultaneously by motor 1, discharge be exactly emulsified liquid with accurate concentration of certain pressure.
Regulate the handwheel of stepless speed variator 4, change its output speed, thereby change the flow of cycloid formula oil scavenge pump 6, just obtain the emulsified liquid of variable concentrations.The handwheel of regulating safety valve 14 just can obtain the emulsified liquid of different pressures, can see the force value of this moment intuitively by pressure meter 13.Stepless speed variator 4 can make the concentration of emulsified liquid adjustable continuously.Safety valve 14 can make the pressure of emulsified liquid stepless adjustable, also plays protection high-pressure plunger pump 10 simultaneously.Water reduction valve 11 has pressure surge and impact in the automatic elimination underground mine water supply pipe network, guarantees pressure medium and the metastable effect of flow behind the valve, guarantees the stability of emulsified liquid process for preparation.One-way valve 8 can prevent that press water from oppositely passing to oil scavenge pump 6, avoids the counter-rotating or the damage of pump.Cut off the electricity supply, turn off water stop valve 12, this device promptly quits work.
