Detailed description of the invention
Describe gas-liquid separator for compressor assembly of the present utility model in detail below in conjunction with accompanying drawing, it will be appreciated by those skilled in the art that embodiment described below is only to exemplary illustration of the present utility model, but not for it being made to any restriction.
As Fig. 1, gas-liquid separator assembly of the present utility model comprises shell separator 2 and muffler 3, and its as described below and the drain pan 1 cylindraceous that is generally compressor are combined common formation gas-liquid separator.
As shown in Figure 2, shell separator 2 comprises cylindrical tube 21 and the outward extending annular roof plate 22 of top level from cylindrical tube 21.The outer peripheral edges of annular roof plate are fixed on the annular inner wall of drain pan 1 of compressor by modes such as for example welding.The circular bottom part of cylindrical tube 21 is fixed on the basal surface of drain pan 1 of compressor by modes such as for example welding.
As shown in Figure 3, muffler 3 has the first inlet end 7, the second exhaust end 8 and is positioned at the spill port 4 of bridge joint bottom.
As Figure 1-3, be provided with through hole 23 on annular roof plate 22, the second exhaust end 8 of muffler 3 protrudes upward through the through hole 23 on annular roof plate 22.The second exhaust end 8 is for example connected (can not leak gas from junction) by sealing gasket or welding manner with annular roof plate 22 air-tightness.The first inlet end 7 of muffler 3 is positioned at the below of adjacent rings top board 22.
After being used to form the interior sealing installation of drain pan 1 shell separator 2 of compressor bottom oil sump, the separated device housing 2 of drain pan 1 is hermetic divided into two isolated areas: the open oil sump of exterior annular closed sandwich (space) and central authorities.In the open oil sump of central authorities, place lubricating oil, the hollow crankshaft (not specifically illustrating) of compressor contacts with lubricating oil, and the bottom of bent axle is positioned at below lubricating oil liquid level.
The air inlet pipe 6 of compressor is communicated with outside closed sandwich.The gas that is mingled with liquid of compressor enters into as mentioned above and forms in gas-liquid separator and carry out gas-liquid separation through compressor air inlet pipe 6.
As shown in Figure 1, muffler 3 is fixedly mounted in the closed sandwich of outside, and the first inlet end 7 of muffler 3 is positioned at closed sandwich inside, outside, and the second 8 of exhaust ends are upward through the through hole 23 arranging on shell separator 2 and stretch out outside closed sandwich.The second exhaust end 8 is unique fluid communication channels of the open oil sump of central authorities and outside closed sandwich, and gas and liquid all circulate by this passage.
Muffler 3 bottoms contact with the basal surface of drain pan 1, on the bridge joint bottom of muffler 3, are provided with spill port 4.The diameter of spill port 4 draws through accurate Calculation and design, and the diameter of spill port 4 is 1-2mm conventionally.According to calculating and multiple mufflers 3 need to also can being installed.The shape of muffler 3 can, according to space or required any selection, be generally illustrated U-shaped.
As shown in figs. 1 and 3, near the second exhaust end 8, can also be provided with pressure compensation opening 5, in the time of compressor shutdown, keep the inside and outside air pressure balance of muffler 3.But the situation that occurs pressure imbalance after compressor shutdown is little, even if there is degree also very slight, therefore in fact also can omit air equalizer opening 5.
The caliber of muffler 3 has determined the speed of air-flow in muffler 3, and when the diameter of muffler 3 and the diameter of compressor inleting pipe 6 are when basic identical, system operation is more good.
Simple description operation principle of the present utility model below.
Because the proportion of gas and liquid is different; the improper return-air of compressor is mingled with the gas of liquid; enter after gas-liquid separator through compressor muffler 6; because sectional area increases suddenly; air velocity reduces; cold-producing medium and lubricated wet goods liquid are assembled downwards under Action of Gravity Field, are deposited on closed sandwich bottom, outside, thereby separated from the gas.And gas rises after departing from liquid, enter muffler from the first inlet end 7 of muffler 3, the second exhaust end 8 of cooled via return air pipe 3 is discharged, and leaves gas-liquid separator, enters compressor.
Be deposited on the liquid in separator, slowly enter muffler 3 through spill port 4 with the speed that does not endanger compressor, open oil sump with the central authorities that are back to of the gas slowly in muffler 3.
As mentioned above, the liquid of carrying secretly in gas is controllably separated, thereby has reduced the impact of time liquid to compressor, improves compressor reliability.
Gas-liquid separator assembly of the present utility model, with the drain pan simple combination that is used to form compressor oil sump, has realized traditional independently external gas-liquid separator function, and the anti-liquid ability of compressor and reliability are provided greatly.
