Description
Technical field
The utility model relates to air pressure pump up water technical field, particularly a kind of air pressure lift pump and pump group.
Background technique
The air pressure lift pump is to realize efficiently pumping up water by the water that air pressure promotes to enter in the water inlet, and it is used for the fields such as water lift or agricultural irrigation, is mainly used in the deep-well water lift.The gas because the water in the water pipe is mixing is so higher than the common lift of pump that pumps up water under same air pressure conditions.
Chinese patent literature 201220029975.3 discloses a kind of air pressure lift pump, it comprises: casing, exhaust regulating valve, control suction valve and outlet pipe, box house is divided into two cylindrical shells, be respectively equipped with inlet valve on the two described cylindrical shells, exhaust regulating valve, control suction valve and outlet pipe, wherein the water inlet position of the outlet pipe in the cylindrical shell is lower than the water inlet position of outlet pipe in another cylindrical shell, the outlet pipe of two cylindrical shells converges formation one main sewer, the maximum amount of water that the filled water amount of described main sewer once can be discharged more than or equal to the higher described outlet pipe place cylindrical shell of water inlet position; Two relief openings are connected with described main sewer by outlet pipe respectively; Be provided with linking mechanism between exhaust regulating valve and the control suction valve, realize staggered exhaust and the drainage procedure of two cylindrical shells by interlock, make one of them cylindrical shell when exhaust, another cylindrical shell is realized draining, and then the water gas that mixing enters in the main sewer together, make the weight reducing of water column in the main sewer, under condition of the same race, improved the draining lift.
Model utility people finds to exist in the prior art following technological deficiency in realizing process of the present utility model:
