Abstract

The invention discloses a double-air-inlet pneumatic lifting pump. The pump comprises a connecting seat, an upper pump body, an upper cavity body, a supporting seat, a lower cavity body and a lower pump body, the connecting seat, the upper cavity body, the supporting seat, the lower cavity body and the lower pump body are sequentially connected, the left side of the upper pump body is sleeved withthe connecting seat, an annular air inlet cavity is formed by the right side of the upper pump body and the lower pump body, and the annular air inlet cavity is used for radial air inlet; the connecting seat, the upper cavity, the upper pump body and the supporting seat cooperatively form a radial air inlet chamber, and the supporting seat, the lower cavity body, the lower pump body and the upperpump body cooperatively form an axial air inlet chamber; a first through hole is formed in the upper cavity, a second through hole is formed in the lower cavity, a plurality of third through holes are formed in the upper pump body, and the third through holes are used for radial air inlet. According to the lifting pump, the negative pressure at a feeding port is increased through radial air inletand axial air inlet, the lifting performance of the lifting pump is improved to a larger extent, and the whole pump has the advantages of compact structure, convenient maintenance, high safety performance reliability, and low in operating and using cost.

Description

technical field [0001] The invention relates to the technical field of lift pumps, in particular to a two-way air intake type pneumatic lift pump. Background technique [0002] During the rapid development in recent decades, my country's terrestrial mineral resources have become insufficient. Minerals such as coal, petroleum, iron, manganese, chromium, copper, and potassium salts have been unable to meet the rapidly growing domestic consumption demand, while petroleum, manganese, The content of iron etc. is directly related to my country's economic construction and military strategic security. Compared with land resources, my country's marine mineral resources are much richer. At present, hundreds of major mineral resources have been discovered in the ocean, including petroleum, seabed coal mines, polymetallic nodules, crust resources and hydrothermal sulfide deposits, especially polymetallic Nodules (also known as manganese nodules) contain many types of rare and precious me...
