Background technology
When centrifugal compressor works, mechanical movement (as oil pump stirs liquid, rotor motion, gear gear motion etc.) and sealing gland
Gases at high pressure constantly lift compressor internal gas pressure, need to be inside and outside by the fabric connectivity compressor such as connecting tube, with
Balance air pressure inside.But when internal cold media gas is by connecting tube, gaseous state lubricating oil can be carried, if it not separated, lubricating oil
It can flow to outside compressor, that is, " running oil " phenomenon occur.On the one hand " running oil " phenomenon causes unit absorbing gas belt liquid, damages the impeller longevity
Life；On the other hand, lubricating oil liquid level is reduced, the parts such as bearing is cannot get sufficient lubrication, unstable wear.Therefore, often in connection
Mono- oil separation part part of Guan Qianjia is to isolate gaseous state lubricating oil.
Oil eliminator can be divided into built-in oil eliminator and external oil eliminator, and separate mode can be divided into the collision point of reduction of speed formula
From, it is centrifugal separation and be separated by filtration, and reduction of speed formula collision separation, it is centrifugal separation frequently as one-level separate mode, mistake
Filter separation is frequently as the second-order separation mode.As shown in figure 1, the conventional two-stage oil separator of existing centrifugal compressor, during work, takes
Mixed gas with lubricating oil enters oil eliminator from air inlet 11, and with the reduction of the collision rift kinetic energy of baffle plate 7, parts of lubricating oil is hindered
Gear, so far completes one-level separation；Mixed gas after reduction of speed enters net-filter assembly 8, and oil droplet is flutterred under collection effect net-filter assembly 8
Aggregation becomes big, and declines under gravity, and gas then continues to rise, and completes the second-order separation and final from the row of gas outlet 12
Go out.
But above-mentioned oil eliminator has the following disadvantages：When the gaseous mixture scale of construction is more, flow velocity is smaller, two baffle plates 7
Collide separating effect reduction, now, a large amount of gases for carrying lubricating oil flow through filter screen vertically, oil droplet have not enough time to aggregation just by
Rear gas breaks up, final lubricating oil with gas flow compressor outside, there is " run about oil " phenomenon.
