However, the constant flow pump with this structure is not suitable for long-term constant flow occasions. Long-term operation is likely to cause wear of the cam pair and fatigue of the return spring.
At the same time, because the cam transmiss

Abstract

The present invention relates to a new type of plunger pump, which includes a driving device, a pump body, a power actuator assembly, and a power transmission assembly; the power actuator assembly includes a guide rod, a chute, and a swing plate that reciprocate in the pump body; The chute is fixedly mounted on one end of the guide rod protruding from the pump body, and the inner side of the chute has two parallel and opposite working planes, the working planes are perpendicular to the guide rod; The power transmission assembly includes an active non-circular gear and a passive non-circular gear meshing with each other, the passive non-circular gear is in transmission connection with the oscillating plate, the active non-circular gear is connected with the driving device, and is driven by the driving device its spinning. The plunger pump can realize the transmission of the sinusoidal mechanism, the pressure angle can be realized by the rotation of the chute and the oscillating disk, and the non-circular gear can realize the smooth movement speed of the guide rod. The equipment is driven by non-circular gears, which can greatly overcome many shortcomings of the cam mechanism, and has a long service life and is not easy to wear.

Description

technical field [0001] The invention relates to a liquid power delivery device, in particular to a novel plunger pump. Background technique [0002] In recent years, the preparative chromatography industry and the supercritical industry have developed rapidly. The development needs of the traditional petrochemical industry, especially the high-pressure fracturing pumps in shale oil fields, require high-pressure plunger pumps with large flow and non-pulsating transport of chemical media, with a pressure range of 5MPa to 100MPa. The flow range is divided into two levels: small flow area laboratory type, 0.01 ~ 500m L / min; large flow industrial manufacturing type, 0.5 ~ 50L / min. The transmission medium is water, methanol, acetone, propylene, butane, liquid carbon dioxide, etc. Generally, no pulse transmission is required for system stability. In the laboratory and other small flow areas, the cam structure transmission device plunger pump constant flow pump is mainly used at pr...
