Montejus equipped with injector
ActiveCN101109397BTo achieve the purpose of raising liquidEfficient jettingPressure pumpsMachines/enginesWater dischargePneumatic valve
The invention relates to a pneumatic fluid lifter with an injector. On a pump body, a control console is installed, which is provided with an compressed air inlet, an air admission channel and an installation hole, in which a distribution box is installed. The compressed air enters into the distribution box through a control cover board, is injected into the exhaust port through an injection hole; negative pressure is produced in the pump body to suck out the air in the pump body, the water-sucking one-way valve opens, the water is sucked into the pump from the pump bottom; the float in the pump raises to push the cone of the pneumatic valve to rise, when the water level reaches to the designed height, the cone closes the exhaust port, the compressed air transfers into the press-in pump, the water-suction port closes, the water discharging port opens, the water is pressed out from the pump body. As the pneumatic fluid lifter has no rotary part, compressed air is used to suck and discharge water, and water is sucked and discharged automatically depending upon the water level, so un-attended operation is achieved, labor is saved. The pneumatic fluid lifter is of simple structure, easy to maintain, low cost, and can work normally at low water level. The pneumatic fluid lifter has no electric apparatus, is explosive proof, is applicable for working in pits of coal mines and environment with explosive gas.
