Problems solved by technology

The disadvantage is that the speed is not high, the machine is large and heavy, the structure is complex, there are many wearing parts, and the amount of maintenance is large. The exhaust is discontinuous, which causes the air flow to fluctuate and cause greater vibration and noise during operation.

Abstract

The invention discloses a volumetric pump. The volumetric pump is composed of a shell part and a transmission part, and is mainly composed of a driving shaft, a driven shaft, a piston pin, a piston, an air cylinder, a left and right end cover, a front and rear sealing cover, an air inlet and outlet valve and the like, wherein the transmission part of the volumetric pump is composed of the drivingshaft, the driven shaft, the piston pin, the piston and the air cylinder; the shell part of the volumetric pump comprises the left and right end cover, the front and rear sealing cover, the air inletand outlet valve and the like; the piston pin is connected with the driving shaft and the piston, the air cylinder is used for bearing an air inlet channel and a lubricating oil channel, and is connected with an external pipeline; a left valve cover and a right valve cover are installed on the two sides of the air cylinder, and play a role in fixing an air inlet and outlet valve plate, so that a closed air inlet and outlet channel is formed, and the two sides of the air cylinder are sealed. The volumetric pump has the advantages of being reasonable in structure, reliable in use, convenient tooverhaul, high in efficiency, small in size, light in weight and the like.

Description

technical field [0001] The invention relates to the field of electromechanical equipment, in particular to a displacement pump. Background technique [0002] As a general-purpose machine, positive displacement pumps have many types and are widely used in various industries of national production. With the advancement of science and technology, especially in recent years, petroleum, chemical, plastic and synthetic materials, and refrigeration processes [0003] With the advancement of science and technology, especially the development of petroleum, chemical industry, plastic and synthetic materials and refrigeration technology in recent years, the country's demand for volumetric pumps is increasing, and the requirements for the quality of volumetric pump products are also getting higher and higher. Among these volumetric pumps, the reciprocating piston volumetric pump accounts for the main share, so improving the volumetric pump device will contribute to the promotion of nati...
