Montejus equipped with injector

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of compressed air lifter (pneumatic pump), and mainly relates to a compressed air lifter equipped with an injector. It has the functions of conveying pump body liquid, exhausting and sucking liquid. Background technique [0002] Existing wind-driven pumps are mainly based on the wind-driven turbine type, which is mainly composed of pump outer body, wind wheel, water wheel, main shaft and other components. When working, the compressed air blows the wind wheel, and the wind wheel drives the water wheel to rotate through the main shaft to lift the liquid. Due to the disadvantages of the pneumatic pump with this structure, such as many rotating parts, easy wear and tear, difficult maintenance, high noise, high water quality requirements, overheating when running dry, no idling allowed, and short service life, etc. Can increase the use cost of the user, there is certain potential safety hazard.
