Gas purification separator

Abstract

The invention relates to a method for assembling a gas purification separator used for separating a flowable mixture. The separator comprises housings of a first housing part and a second housing part, and rotor assemblies which are located in inner spaces and can rotate, wherein the first housing part is provided with a registration surface; a reference surface of the second housing part pushes against the registration surface for registration, so that the inner spaces of the housings are limited conveniently; and the rotor assemblies comprise a rotating shaft which can be rotationally mounted on the first housing part and the second housing part. The method comprises the steps that the rotating shaft can be rotationally mounted at the second housing part in a preset position; when the reference surface of the second housing part is registered with the registration surface of the first housing part, the preset position is coincided with an axis; a bearing unit is located in a fixture, so that the bearing unit is received in the following position by the fixture: when a reference surface of the fixture is registered with the registration surface of the first housing part, the position is coincided with the axis; the reference surface of the fixture is located to be registered with the registration surface of the first housing part; and the bearing unit is fixed at the first housing part.

Description

technical field [0001] The present invention relates to a separator, and more particularly but not exclusively to a centrifugal separator for the purification of gaseous fluids. Background technique [0002] It is well known that mixtures of fluids with different densities can be separated from each other by using centrifugal separators. A specific use of such separators is for separating oil from gases discharged from the crankshaft housing of an internal combustion engine. [0003] With regard to this particular use of the separator, it is readily understood that the high pressure gases present in the combustion chamber of an internal combustion engine have a tendency to leak through the associated piston rings and into the crankshaft housing of the engine. Such continued leakage of gas into the crankshaft housing can result in an undesirable increase in pressure within the housing and, as a result, the need to bleed gas from the housing. In large commercial vehicles, th...

AI Technical Summary

Problems solved by technology

[0007] First, the fluid path through the separator causes a pressure loss which can adversely affect the flow capability of the separator and thus the size of the engine with which the separator can be used

Therefore, it can be considered that the first type of problem associated with prior art LFDEX® separators involves pressure loss in the fluid flow path

[0008] Second, prior art separators are arranged such that under certain conditions the purge gas can become contaminated before leaving the separator

Therefore, it can be considered that a second type of problem associated with prior art separators involves undesirable oil contamination of the purge gas

[0009] Third, certain manufacturing techniques and structural features associated with prior art separators can lead to assembly difficulties and / or reliability issues

Therefore, it can be considered that a third class of problems associated with prior art separators concerns the manufacture and reliability of the separators
