Description

Gas-liquid separator

Technical field

The utility model relates to refrigeration part field, is specifically related to gas-liquid separator.

Background technology

At present, many employing Multi-compressor parallel systems within air-conditioning systems, problem of oil return is always

Restrict one of key factor of its development, the basic role of lubricating oil is the effect of its lubrication, to reduce the frictional dissipation between moving component.Within the compressor lubricating oil have lubrication, cooling and sealing triple function, be restriction compressor performance key factor.According to statistics, when the oil content in compressor is less than 7%, along with its volumetric efficiency of increase of compressor oil content also raises gradually.This is because when oil content is less within the compressor, oil mass increase then means the raising of compressor seal, flow resistance at air valve place increases, actual pressure of inspiration(Pi) reduces, but the inspiratory volume increase of compressor to be said when its oil content is greater than 9.1% then on the contrary, this is because the lubricating oil now in compressor occupies certain volume, its aspirated volume reduces, frictional force increases, and friction loss increases, and then causes the reduction of volumetric efficiency.Gas-liquid separator is a very important part in refrigeration system, is responsible for the normal operation of protection compressor.Generally, gas-liquid separator is arranged on the porch of evaporator outlet and compressor, when the cold-producing medium in evaporimeter does not evaporate completely, will enter compressor inside with liquid condition, produces liquid hit phenomenon, thus cause the damage of compressor to compressor.

Summary of the invention

In order to solve the problem, the utility model provides a kind of structure simple, by gas and fluid separation applications, reduces compressor liquid hit phenomenon, safe and reliable gas-liquid separator.

The utility model gas-liquid separator, comprise body, described body is a seal case, be provided with a U-shaped pipe in described body, described body be provided with outlet and inlet tube, described outlet and inlet tube are all arranged on body outside, the port of export of described U-shaped pipe is connected with outlet, the arrival end of described U-shaped pipe is arranged on body top, described U-shaped pipe is also provided with a filter, is provided with discharge line bottom described body.

Preferably, filter is provided with a spill port.

Preferably, U-shaped pipe bottom is connected with body by fixed head.

Preferably, the upper and lower two ends of body are respectively arranged with a upper end cover and bottom end cover.

The utility model structure is simple, by gas and fluid separation applications, reduces compressor liquid hit phenomenon, safe and reliable.

The utility model utilizes spill port to carry out recycling to the lubricating oil entered in gas-liquid separator, improves the reliability of system oil return.

Accompanying drawing explanation

Fig. 1 is the structural representation of gas-liquid separator.

Reference numeral: 1-body, 2-inlet tube, 3-outlet, 4-fixed head, 5-filter, 6-upper end cover, 7-bottom end cover, the arrival end of 8-U shape pipe, 9-U shape is managed.

Detailed description of the invention

The utility model gas-liquid separator, comprise body 1, described body 1 is a seal case, be provided with a U-shaped pipe 9 in described body 1, described body 1 be provided with outlet 3 and inlet tube 2, it is outside that described outlet 3 and inlet tube 2 are all arranged on body 1, the port of export of described U-shaped pipe is connected with outlet 3, the arrival end 8 of described U-shaped pipe is arranged on body 1 top, described U-shaped pipe 9 is also provided with a filter 5, is provided with discharge line bottom described body 1.Filter 5 is provided with a spill port.U-shaped pipe 9 bottom is connected with body 1 by fixed head 4.Body about 1 two ends are respectively arranged with a upper end cover 6 and bottom end cover 7.

Its separation principle utilizes cryogen gaseous different with liquidus density, gas-liquid mixture phase fluid is flowed through when inlet tube 2 enters diameter larger body 1 utilize sudden enlargement aisle spare and its flow velocity is reduced, change its flow direction simultaneously, liquid sinks gas is floated.Gas enters through the entrance point 8 of U-shaped pipe, and the spill port of gas flow on filter 5 will produce certain negative pressure, draws parts of lubricating oil, and enters compressor through U-shaped pipe 9.Its concrete path is: enter in body 1 from evaporimeter gas-liquid mixed state cold-producing medium out by inlet tube 2, gaseous refrigerant enters the rear Diffusion of gas stream of body 1, owing to there is no the liquid refrigerant itself of vaporizing than gas weight, can directly fall into bottom body 1, the cold-producing medium of vaporization is then gone up warp float wireway and is entered in compressor from outlet 3, thus prevents compressor suction liquid refrigerant to cause liquid hammer.Simultaneously; the long-term running of compressor; its inside has certain lubricating oil and discharges with the cold-producing medium of vaporization; enter in body 1 by inlet tube 2; under the suction of compressor; these lubricating oils, after the filtration of filter 5 filter screen, enter in compressor through spill port from escape pipe, play again lubrication protection effect like this to compressor.
