Abstract
The utility model relates to a rotary compressor reservoir which is provided with an air intake tube with an adjustable oil return hole. The utility model comprises a casing, an air inlet which is communicated with the inner chamber of the casing, a filtering net, a filtering net support frame, and upper and lower air suction tubes which are arranged mutually in parallel and respectively penetrate through the filtering net and the bottom wall of the casing; the filtering net support frame is provided with a through hole; the lower parts of the air suction tubes are provided with oil return holes which are communicated with a pump body; the air suction tube is fixed by a fixing frame. The utility model is characterized in that the position of the oil return hole of the lower air suction tube is higher than the position of the oil return hole of the upper air suction tube. Because the position of the oil return hole of the upper air suction tube is low, engine oil can firstly enter the upper air suction tube, and the oil supply condition of an upper cylinder is improved.
Description
The utility model relates to rotary dual cylinder compressor, specifically, relates to the reservoir of rotary dual cylinder compressor.
For preventing that the pump housing that liquid coolant directly enters rotary compressor from causing the pump housing to damage, rotary compressor disposes reservoir at air entry usually.Rotary dual cylinder compressor respectively has a compression cylinder up and down, they in running respectively two air intake ducts up and down by reservoir suck cold media gas and be dissolved in the refrigerator oil of refrigerant.For after the refrigerant of gas liquid mixture enters from the import of reservoir together with the refrigerator oil that dissolves each other, at first pass through filter screen, behind the intercommunicating pore of offering by filter screen bracket, liquid part wherein, the mixture that is refrigerator oil and liquid coolant accumulates in the reservoir bottom, enter compressor pump from air intake duct behind the cooling medium liquid evacuator body that accumulates, refrigerator oil and a spot of liquid coolant enter the pump housing by the spill port of air intake duct bottom.The pump housing of double-cylinder compressor needs refrigerator oil to be lubricated, to seal and dispel the heat in running, except from reservoir, sucking the refrigerator oil, main pump whelk blade by pump housing bottom bent axle internal diameter pumps into refrigerator oil, again by the fuel feeding aperture on the bent axle to pump housing fuel feeding.Because two cylinders of rotary dual cylinder compressor are arranged to one on the other, the refrigerator oil that the pump whelk blade of pump housing bottom bent axle internal diameter pumps into enters lower cylinder and upper cylinder more difficult to get access easily.Like this, under the situation of fuel delivery deficiency, upper cylinder occurs the oil starvation situation easily than lower cylinder and causes the wearing and tearing of the upper cylinder part pump housing.The Position Design of the spill port originally on the air intake duct becomes to be in sustained height, therefore can not compensate the deficiency of upper cylinder pump housing part fuel feeding.
Therefore, the purpose of this utility model provides a kind of rotary double cylinder compressor reservoir that improves rotary double cylinder compressor upper cylinder pump housing fuel feeding deficiency.
For achieving the above object, the utility model provides a kind of rotary dual cylinder compressor reservoir with air intake duct of band adjustment type spill port, and it comprises: a reservoir housing, is arranged on import, that described housing upper end is communicated with the housing inner chamber and is arranged on the filter screen bracket of fixedlying connected with inner walls in the described inner chamber, is arranged on filter screen and the be parallel to each other layout and respectively pass the up and down air intake duct of described filter screen bracket and shell bottom wall of housing top inner chamber between import and filter screen bracket; Described filter screen bracket offers the through hole that is communicated with the housing inner chamber, and the bottom of described air intake duct is provided with the spill port that is communicated with the pump housing, and described air intake duct is fixed by the fixed mount of fixedlying connected with inner walls; Be characterized in that the described position of the spill port of air intake duct down is higher than described spill port position of going up air intake duct.
Adopt technique scheme of the present utility model, because the spill port of traditional reservoir air intake duct is designed to adjustment type, the position of spill port of last air intake duct that is reservoir is lower, when the refrigerator oil height that accumulates in the reservoir raises, machine oil will be introduced into air intake duct, thereby remedied upper cylinder fuel feeding deficiency, improved the greasy property of compressor pump.
One preferred embodiment specifically describes to the utility model below with reference to accompanying drawings, so that clearlyer understand the purpose of this utility model, characteristics and advantage.
Fig. 1 is the structure chart of the rotary double cylinder compressor reservoir with air intake duct of being with the adjustment type spill port of the utility model one preferred embodiment;
Fig. 2 is the structure for amplifying schematic diagram of lower part of the reservoir of Fig. 1 embodiment.
As shown in the figure, the rotary dual cylinder compressor reservoir of the air intake duct with band adjustment type spill port of the utility model one preferred embodiment comprises: a reservoir housing 1, is arranged on import 3, that housing 1 upper end is communicated with housing inner chamber 2 and the filter screen bracket 4 of fixedlying connected with housing 1 inwall in the inner chamber 2 is set, is arranged on filter screen 5 and the be parallel to each other layout and respectively pass last air intake duct 6 and the following air intake duct 6 ' of described filter screen bracket 4 and shell bottom wall of housing 1 top inner chamber 2 between import 3 and filter screen bracket 4.Filter screen bracket 4 offers the through hole (not shown) that is communicated with housing inner chamber 2, and air intake duct 6,6 ' bottom are provided with the spill port 8 and 9 that is communicated with the pump housing up and down, and air intake duct 6,6 ' is fixing by the fixed mount 7 of fixedlying connected with housing 1 inwall; The position of the spill port 9 of following air intake duct 6 ' is higher than the position of the spill port 8 of air intake duct 6.Like this, because the position of the spill port 8 of the last air intake duct 6 of reservoir is lower, when the refrigerator oil height that accumulates in the reservoir raises, the deficiency of air intake duct 6 with compensation upper cylinder 10 fuel feeding will preferentially be entered, promptly play to regulate entering the effect of the lubricants capacity in the upper and lower air cylinders 10,11, thereby improved the greasy property of compressor pump.
Above-mentioned reservoir with air intake duct of band adjustment type spill port uses on the rotary double cylinder compressor of developing the applicant.To its with adopt The actual running results of traditional rotary dual cylinder compressor of the reservoir of traditional air intake duct the analysis showed that: adopt the reservoir of the air intake duct of band adjustment type spill port of the present utility model to improve the fuel feeding situation of upper cylinder effectively with band co-altitude spill port, and adopt traditional air intake duct with band co-altitude spill port, the fuel feeding deficiency but takes place in upper cylinder, and makes upper cylinder part pump housing component wear bigger.Therefore the utlity model has the effect of significant raising compressor pump greasy property.
