Compressor is as the core component of air-conditioning, the Performance And Reliability of compressor plays important effect to the overall performance of air-conditioning system, and the lubrication effect of compressor and the cycle characteristics of lubricant oil then are one of key factors that influences compressor performance and reliability.Generally oil separator can be set for the rotary compressor below 5, when the exhaust oil content of compressor was too high, lubricant oil entered into system, and then had influence on the heat exchange effect of two devices, thereby reduced the performance of system; And too high exhaust oil content is unfavorable for oil return, influences the reliability of compressor easily.
During compressor operating, under action of centrifugal force, lubricant oil enters from oil inlet hole, enters into lower flange, cylinder, the lubricated kinematic pair of upper flange respectively through oilhole.
First kind of structure of existing compressor crank shaft as shown in Figures 1 and 2, when high frequency turns round, lubricant oil enters and rises to bent axle body 6 upper ends through oil channel 7 from oil inlet hole 8, from the ejection of the through hole at bent axle body 6 upper end plug cocks 11 centers and enter into outlet pipe, thereby strengthened the exhaust oil content of compressor.
Second kind of structure of existing compressor crank shaft as shown in Figure 3; oil duct 7 adopts blind hole structure; on bent axle body 6, offer the oil outlet 9 of bypass; can effectively reduce the exhaust oil content of compressor; but this structure is easy cleaning not, and the chip impurity after the processing remains in the bent axle easily, enters in the compressor pump easily when compressor operating; influence the performance of compressor, when serious even cause the stuck and compressor shutdown of the pump housing.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, a kind of compressor crank shaft is provided and uses the compressor of this bent axle, and the utility model can effectively reduce the oil content of compressor air-discharging, cleans also more convenient.
Its technological scheme is as follows.
A kind of compressor crank shaft comprises the bent axle body, is provided with oil duct longitudinally in bent axle body inside, and this oil duct comprises oil inlet hole and oil outlet, and oil inlet hole is positioned at the lower end of bent axle body; The upper end of oil duct extends to form through hole to the upper end of bent axle body, is provided with the plug cock that is used to seal through hole in last through hole, and the oil outlet of oil duct is to the circumferential side wall bypass of bent axle body.
A kind of compressor, comprise housing, in housing, be provided with bent axle, lower flange, upper flange and cylinder, bent axle cooperates with lower flange, upper flange and cylinder, lower part of frame is an oil pocket, bent axle body inside at bent axle is provided with oil duct longitudinally, and this oil duct comprises oil inlet hole and oil outlet, and oil inlet hole is positioned at the lower end of bent axle body and communicates with oil pocket; The upper end of oil duct extends to form through hole to the upper end of bent axle body, is provided with the plug cock that is used to seal through hole in last through hole, and the oil outlet of oil duct is to the circumferential side wall bypass of bent axle body.
Below the further technological scheme of the utility model is described.
Described oil duct comprises main paragraph and the bypass section that communicates, and described oil inlet hole reaches goes up lower end and the upper end that through hole lays respectively at main paragraph, and described oil outlet is positioned on the bypass section.
Between described oil inlet hole and oil outlet, also be provided with the oilhole that communicates with described oil duct.
Described plug cock comprises circular catch and is positioned at the anti-flake of catch periphery.
Below advantage of the present utility model is described.
Because the oil outlet of oil duct is not arranged on the upper end of bent axle body, that is to say that 1, when high frequency moved, the lubricant oil in the oil duct can not reduce the exhaust oil content of compressor directly from the upper end ejection of bent axle body, has improved the reliability of compressor.
2, after the plug cock that will go up the through hole takes off, can clean easily, avoid remaining in the stuck phenomenon that causes in the bent axle owing to chip and impurity.
