Abstract

The invention discloses a plunger pump and belongs to the technical field of fluid pumps. The plunger pump comprises a pump body, wherein a partition wall is arranged in the pump body close to a material inlet, a mounting barrel is arranged in the pump body between the partition wall and a plunger, and a transmission shaft is rotatably arranged on the mounting barrel. A turntable is fixedly arranged on the transmission shaft in a cavity, a floating plate is arranged between the partition wall and the turntable, an impeller is fixedly arranged on the transmission shaft, and feeding channels are formed between every two adjacent blades. Circulation gaps are formed between the floating plate and the turntable, and a plurality of through holes corresponding to the circulation gaps at positions are formed in the mounting barrel. The transmission shaft penetrates out from one end of the mounting barrel to be connected with the plunger. A sleeve is slidably arranged on the outer surface of the mounting barrel and is connected with the plunger through a connection rod. A material outlet is arranged on the pump body and connected with a ball valve which is controlled by the plunger. The plunger pump solves the technical problems of the existing plunger pump of insufficient suction volume and excessive leakage amount, and is widely applied to continuous fluid transportation.

Description

technical field [0001] The invention relates to a pump, more particularly to a plunger pump, and belongs to the technical field of fluid pumps. Background technique [0002] The plunger pump is an important device of the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize functions such as oil absorption and oil pressure. Because the plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, it is widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, engineering machinery and ships. [0003] The traditional plunger pump is a kind of reciprocating pump, which belongs to the volume pump. Its plunger is driven by the eccentric rotation of the pump shaft to reciprocate, and its suction and discharge valves are check valves. When the plunger is pulled outward, the pressure i...
