Abstract

The invention discloses a rotor pump and an assembly method thereof, belonging to the technical field of rotor pumps. The rotor pump includes a casing; a first transmission shaft, one end of which is provided with a first bearing, and the first bearing is arranged in a first bearing seat on the casing, and the first transmission shaft is provided with a first Rotor; second transmission shaft, which is parallel to the first transmission shaft, the second transmission shaft is provided with a second rotor, one end of the second transmission shaft is provided with a second bearing, and the second bearing In the second bearing seat provided on the housing, injection molding grooves are provided on the outer peripheral wall of the second bearing and / or on the upper ring of the inner peripheral wall of the second bearing seat for injection molding and containing injection molding agent. Its advantage is that it can adjust the rotation gap between the first rotor and the second rotor without disassembly, and at the same time keep the rotation gap between the first rotor and the second rotor unchanged during the rotation process .

Description

technical field

[0001] The invention relates to the technical field of rotor pumps, in particular to a rotor pump and an assembly method thereof. Background technique

[0002] The rotor pump refers to the pump that changes the working volume through the relative movement between the rotor and the pump body, thereby increasing the energy of the gas or liquid; the rotor of the rotor pump rotates without impact, with high speed, compact structure, and relatively small volume. Small, so when transporting gas or liquid, the rotor pump has incomparable advantages over other pumps.

[0003] However, in the existing rotor pump, in order to make the main transmission shaft and the driven shaft keep parallel to each other during the rotation process, so that the rotation gap between the rotor on the main transmission shaft and the rotor on the driven shaft is not large. Angle deviation occurs to prevent the rotor on the main transmission shaft from colliding with the rotor on the dri...
