Background technique
At present, in coal mining, in order to reduce coal dust, gas and prevent spark, generally adopt wet type coal winning technology.It is exactly by boring that so-called wet type is mined, and press water and the aqueous solution is injected coal body, moisturizes, to change the physico-mechanical properties of coal, can reduce the generation of coal dust, also can reduce bump, and coal and coal-seam gas are given prominence to and spontaneous combustion.Pumping water into coal adopts coal-bed flooding pump.Current coal-bed flooding pump generally adopts electrodynamic type coal-bed flooding pump.Electrodynamic type coal-bed flooding pump is primarily of motor, the pulse pump housing, the pressure governor being with throttling arrangement and pressure display unit composition.The pump housing exports high voltage pulse water, pressure regulator control impuls hydraulic pressure under the hydraulic pressure of setting, according to the penetrating power automatic regulating water flow amount in water filling coal seam.Because underground coal mine power supply uses inconvenience, the large heaviness of motor volume, the reasons such as the structure of the pulse pump housing itself, so electrodynamic type coal-bed flooding pump moves inconvenience, export the weak effect of high voltage pulse water.
Summary of the invention
In order to overcome the deficiency of existing coal-bed flooding pump, the utility model designs a kind of air pulsing formula coal-bed flooding pump.
A kind of air pulsing formula coal-bed flooding pump, it is characterized in that, it is made up of the piston in the pump housing, the pump housing, the air operated reversing valve on the pump housing, inlet pipeline and rising pipe; The described pump housing has the little reducing piston cavity of mid diameter large two ends diameter, large piston cavity is called wherein, two ends are called small piston chamber, the end, small piston chamber at two ends is equipped with water inlet and osculum, two water inlets at two ends are connected with inlet pipeline respectively by water feeding one-way valve, and two osculums at two ends are connected with rising pipe respectively by going out water one-way valve; Piston in the described pump housing is three disjunctor pistons mated with reducing piston cavity; Two air outlet holes of the air operated reversing valve on the described pump housing communicate with large piston cavity two end part respectively, and air operated reversing valve changes alternately to large piston both sides air feed, thus promotion disjunctor piston moves back and forth; When disjunctor piston moves back and forth, the small piston chamber at two ends alternately produces negative pressure and malleation simultaneously respectively, and one end of negative pressure absorbs water from inlet pipeline, and one end Jiang Shui of malleation is discharged in rising pipe, thus makes water injection pump generation pulsating water press to coal seam high pressure water injection.
Further, enter clean water to protect positive water injection pump, inlet pipeline is serially connected with water filter.
Further, in order to regulate and grasp water injection pressure, rising pipe is connected with safety pressure-regulating valve, safety pressure-regulating valve is provided with pressure gauge and backwater mouth, and backwater mouth is connected by backwater one-way valve and inlet pipeline, and the backwater of safety pressure-regulating valve is back in inlet pipeline.
Further, in order to regulate bleed pressure, supply air line is provided with source of the gas pressure regulator valve.
Good effect of the present utility model is: 1, owing to adopting underground coal mine source of the gas to be used as power, easy to use, and after eliminating motor body, long-pending size is lightweight, is convenient to move at any time; 2, can according to the automatic regulating impulse intensity of the penetrating power in coal seam, the high pressure water of pulse is injected the process of inside, coal seam, under the condition in not pressure break coal seam, " water attack " phenomenon that high voltage pulse water is formed in inside, coal seam, the inner original occlude crack in coal seam is forced to communicate with each other or directly in coal seam, form new fracture network, there is provided water at the network channel of coal seam internal flow, static pressure water is inner to coal seam by these network penetration, coal seam is obtained effectively moistening.
