Description

The novel centrifugal type oil eliminator

Technical field

The utility model relates to a kind of device that separates lubricating fluid from cold-producing medium, particularly relates to a kind of oil eliminator of upper intake lower outlet type.

Background technology

The circulation of lubricating oil if the lubricating oil of taking out of with compressor air-discharging can not return compressor fully, will cause the compressor lubrication fault, badly damaged compressor to the important role in safe operation of refrigeration system.

Being used for oil eliminator that refrigeration system oil separates has a variety ofly, and the Gravity Type Oil separator that divides oil by gravity is for example arranged, and has inner to fill the filtration formula oil eliminator that filler carries out branch oil, and the centrifugal oil eliminator that carries out branch oil by centrifugal force is arranged.Divide oily oil eliminator except installation is restricted by gravity, its oil-dividing efficiency is lower, is difficult to satisfy the requirement that divides oil under many circumstances; The material filling type oil eliminator has very high oil to separate effect, but because that its filler is filled is very close, along with the long-time use of refrigeration system, its resistance can increase gradually, and filler uses stainless steel cloth mostly in addition, and cost is higher; Centrifugal oil eliminator is a rotation effect of making air-flow, by centrifugal force oil droplet is thrown on the bucket wall of separator to carry out branch oil, also can reach the oily effect of good branch.

In order to reach the rotate effect after air-flow enters separator, the structure of present centrifugal oil eliminator mostly is air inlet and to give vent to anger be vertically arranged.The for example Chinese utility model patent patent No. is 88214249.6 centrifugal filtration formula oil eliminator, is to rely on centrifugal force and internal screen to reach the oily effect of branch, adopts the side air inlet, the form of side exhaust, and volume is bigger, and cost is higher; The Chinese invention patent publication number is the application for a patent for invention of the oil separator of CN1766466A, and this patent adopts the side air inlet, the top exhaust, and the version of draining the oil in the bottom surface, the inner centrifugal force that adopts carries out branch oil, and simple in structure, cost is lower.But most of situation lower compression machine exhaust outlet and condenser air inlet are not to be arranged vertically, and bring difficulty will for like this connection of pipeline.
