Description

Core centrifuge rotor

Technical Field

The utility model relates to a centrifuge rotor, in particular to a core centrifuge rotor.

Background

The core sample is a substantially cylindrical test piece of subterranean material taken from the ground for testing by a special drill. The samples collected for general oil exploration are cylindrical cores formed by 1 inch or 1.5 inch drill bits. The centrifugal force is needed to separate the liquid crude oil in the rock core, the horizontal centrifugation mode is reasonable, but the rotor of the horizontal centrifugation is generally low in rotating speed and centrifugal force. To increase the rotational speed and the centrifugal force, only angular rotors are able to achieve this.

In conclusion, the utility model designs the core centrifuge rotor, and adopts the composite rotor, namely the horizontal rotor is arranged inside and the angular rotor is arranged outside, so that horizontal centrifugation is realized, the rotating speed and the centrifugal force are improved, and the centrifugation requirement of the core is met.
