Abstract

The invention provides a pump assembly, a fluid machinery and heat exchange equipment. The pump assembly comprises: at least two structure members; a gas cylinder positioned between the two structuremembers; a roller assembly, wherein the roller assembly comprises a transmission roller and a compression roller connected to the transmission roller, and the compression roller is positioned in the gas cylinder; and a rotation shaft, wherein the rotation shaft penetrates through each structure member, the eccentric portion of the rotation shaft is arranged in the transmission roller in a penetrating manner and drives the transmission roller to move, the transmission roller drives the compression roller to move in the gas cylinder, and the eccentric portion and the transmission roller are immersed in a lubricating medium. According to the present invention, the problem that the friction loss easily occurs between the rotation shaft and the roller of the pump assembly in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of pump body components, in particular to a pump body component, fluid machinery and heat exchange equipment. Background technique [0002] In the prior art, the rotor-type pump body assembly usually consists of an upper flange, a lower flange, a rotating shaft, a cylinder, rollers and sliding vanes. Wherein, the roller is sleeved outside the eccentric part of the rotating shaft, and both the roller and the eccentric part are in the compression chamber. However, during the operation of the pump body assembly, the compression chamber is in a high temperature state, resulting in a decrease in the viscosity of the lubricating oil between the eccentric part of the rotating shaft and the inner circle of the roller, and the friction loss between the eccentric part of the rotating shaft and the roller is very easy to occur. It affects the working performance and working efficiency of the pump body components. Co...
