Description
Technical field
The utility model relates to technical field of refrigeration compressors, relates in particular to a kind of rotary compressor that spiral Oil Guide sheet is set.
Background technique
Compressor is that compression refrigerant makes it participate in the circuit nucleus equipment in the air-conditioning system, rotary compressor is a kind of compressor commonly used, rotary compressor generally comprises rotary compressor and waves compressor, rotary compressor is provided with motor, housing assembly and eccentric compression unit in seal casinghousing, the rotating shaft of motor drives eccentric compression unit and works in the cylinder of housing assembly.
For lubricated eccentric compression unit, be connected to the endoporus oil duct of oil sump rotating shaft being provided with, the endoporus oil duct is horizontally arranged with the oilhole that is connected to eccentric compression unit in place, the endoporus oil duct is provided with spiral Oil Guide sheet, when the compressor operating motor rotates, spiral Oil Guide sheet is communicated to the lubricant oil in the oil sump, and lubricant oil is pumped into the oil-hole location of endoporus oil duct, and lubricant oil enters eccentric compressing member the lubricated work of eccentric compression unit from oilhole.
Compressor is under normal operation, and the pasta position in oil sump is substantially to half position of cylinder, lubricant oil be easy to by spiral Oil Guide sheet enter participate in the compression unit of compressor lubricated.But in some cases, the pasta of compressor is on the low side, can only reach the lower flange position of compressor casing assembly, usually can produce following two kinds of situations this moment: 1, when the pitch of spiral Oil Guide sheet is excessive, time operating angle at spiral Oil Guide sheet pump oil is less, axial thrust load is less, the pump oil mass is less, the oil mass that arrives oilhole position (especially being arranged on the top oilhole) is very little, the oil mass that enters compressor unit from oilhole is less, to compression unit fuel feeding deficiency, influence the reliability of compressor when causing compressor operating; 2, when the pitch of spiral Oil Guide sheet is too small, time operating angle at spiral Oil Guide sheet pump oil is bigger, and axial thrust load is bigger, and the pump oil mass is more, in long axial pump oil process, produce more eddy current in the lubricant oil of carrying, thereby oily stream is interfered, the fuel feeding resistance increases, the oil mass that arrives the oilhole position is very little, the oil mass that enters compressor unit from oilhole is less, to compression unit fuel feeding deficiency, influences the reliability of compressor equally when causing compressor operating.The problem of compression unit fuel feeding deficiency when at present, the spiral Oil Guide sheet that is difficult to suitable pitch solves rotary compressor oil sump low level pasta.
The model utility content
Of the present utility model is to cross the low problem that causes the fuel feeding deficiency at present rotary compressor because of the oil sump pasta, and a kind of rotary compressor that spiral Oil Guide sheet is set is provided.
For reaching above purpose, adopt following technological scheme:
A kind of rotary compressor that spiral Oil Guide sheet is set, described rotary compressor includes housing, motor, housing assembly, eccentric compression unit, motor, housing assembly, eccentric compression unit and is arranged in the seal casinghousing, housing assembly comprises that cylinder and lid are located at the upper flange at cylinder two ends, lower flange, housing assembly is fixed in the housing, motor is arranged on the top of housing assembly, the rotating shaft of motor drives the eccentric compression unit that is arranged in the cylinder, and the below of housing assembly is provided with oil sump; There is the endoporus oil duct that is connected to oil sump the lower end of described machine shaft, be horizontally arranged with the oilhole that is connected to eccentric compression unit on the endoporus oil duct, the endoporus oil duct is provided with spiral Oil Guide sheet, described spiral Oil Guide sheet the helical pitch of lower end less than above the pitch of spiral Oil Guide sheet.
The bottom of wherein said endoporus oil duct is provided with elasticity and fastens spiral Oil Guide sheet.
The beneficial effects of the utility model are: rotary compressor of the present utility model, there is the endoporus oil duct that is connected to oil sump the lower end of machine shaft, be horizontally arranged with the oilhole that is connected to eccentric compression unit on the endoporus oil duct, the endoporus oil duct is provided with spiral Oil Guide sheet, spiral Oil Guide sheet the helical pitch of lower end less than above the pitch of spiral Oil Guide sheet; In the compressor operation, when lubricant oil pasta in the oil sump is low, the less Oil Guide sheet of pitch that spiral Oil Guide sheet is in the lower end contacts with oil sump lubricant oil, this section Oil Guide sheet operating angle is big, help increasing fuel delivery and charge oil pressure, in lubricant oil makes progress course of conveying, spiral Oil Guide sheet top screw piece has bigger pitch, thereby subtract the formation of primary oil flow eddy current, reduce the fuel feeding resistance, the oil mass that arrives the oilhole position is very big, and the oil mass that enters compressor unit from oilhole is more, abundant to the compression unit fuel feeding, the reliability of guarantee compressor.
