본 고안은 압축기의 급유장치에 관한 것으로, 특히 횡형 로타리압축기의 급유장치로서 오일 급유량을 증대시킬 수 있도록 한 것이다.The present invention relates to a refueling device of a compressor, and in particular, to increase the oil supply amount as a lubrication device of a horizontal rotary compressor.
종래 횡형 압축기의 급유장치는 제 1 도 및 제 2 도와 같이 케이스(1)내에 형성된 스테이터(2)와, 상기 스테이터(2)내에 삽입되어 자기력으로 회전하는 로터(3)가 축설된 회전축(4)과, 사이 회전축(4)에 의하여 편심운동을 하면서 압축하는 압축부(5)와, 상기 회전축(4)의 회전구동에 의하여 회전운동을 하는 롤러(6)와, 상기 롤러(6)의 회전운동과 스프링(7)의 탄성력에 의하여 왕복운동을 하는 베인(8)과, 상기 베인(8)의 왕복운동과 오일펌핑실(9)의 전후에 설치된 유체다이오드(10)(10')에 의하여 회전축(4)에 형성된 축구멍(11)으로 오일을 급유하는 급유관(12)과, 상기 축구멍(11)으로 급유된 오일이 압축부(5)의 습동부가 윤활작용을 하도록 급유하는 급유구멍(13)이 구성되었다.The conventional lubricating device of the horizontal compressor has a stator 2 formed in the case 1 as shown in FIGS. 1 and 2, and a rotating shaft 4 having a rotor 3 inserted into the stator 2 and rotating with magnetic force. Compression unit 5 for compressing while eccentric movement by the rotating shaft (4) between, and the roller (6) for rotational movement by the rotational drive of the rotating shaft (4), the rotational movement of the roller (6) And a rotating shaft by the vane 8 reciprocating by the elastic force of the spring 7 and the fluid diodes 10 and 10 'provided before and after the reciprocating motion of the vane 8 and the oil pumping chamber 9. Oil supply pipe (12) for supplying oil to the shaft hole (11) formed in the (4), and oil supply hole for supplying the oil supplied to the shaft hole (11) to lubricate the sliding part of the compression section (5) (13) was constructed.
그리고 14는 윤활유이다.And 14 is lubricant.
이와 같이 종래의 급유장치는 베인(8)의 왕복운동을 이용하여 횡형 압축기의 바닥에 담겨 있는 오일이 오일펌핑실(9)을 통하여 공급한다.As described above, the conventional oil supply device supplies the oil contained in the bottom of the horizontal compressor using the reciprocating motion of the vanes 8 through the oil pumping chamber 9.
그리고, 유체다이오드(10)(10')의 특성상 오일펌핑실(9)의 체적이 증가할 때 (즉, 베인(8)이 상사점에 도달한 경우)에는 오일이 오일펌핑실(9)에 유입된다.In addition, when the volume of the oil pumping chamber 9 increases due to the characteristics of the fluid diodes 10 and 10 '(i.e., when the vanes 8 reach the top dead center), the oil enters the oil pumping chamber 9; Inflow.
또한, 오일펌핑실(9)의 체적이 감소할 때 (즉, 베인(8)이 하사점에 도달한 경우)에는 오일펌핑실(9)에 유입된 오일이 급유관(12)을 통하여 회전축(4)의 축구멍(11)에 공급된다.In addition, when the volume of the oil pumping chamber 9 decreases (that is, when the vane 8 reaches the bottom dead center), the oil flowing into the oil pumping chamber 9 is rotated through the oil supply pipe 12. It is supplied to the shaft hole 11 of 4).
그러나, 이때 오일펌핑실(9)에 유입된 오일이 급유관(12)으로 흘러가는 반면에 유체다이오드(10)쪽으로 역류하여 도리어 오일펌핑실(9)에서 방출되는 오일도 생기게 되어 효율이 떨어지게 되는 문제점이 있다.However, at this time, while the oil flowing into the oil pumping chamber 9 flows into the oil supply pipe 12, the oil is flowed back toward the fluid diode 10 to generate oil released from the oil pumping chamber 9. There is a problem.
또한, 베인(8)이 상승하여 오일이 오일펌핑실(9)에 유입되는 경우에도 급유관(12)에 차 있는 오일이 회전축(4)쪽으로 밀려 올라가기 보다는 오히려 역류하여 오일이 오일펌핑실(9)에 유입되는 것을 방해하는 유체저항으로 작용하게 되는 문제점이 있었다.In addition, even when the vanes 8 are raised so that the oil flows into the oil pumping chamber 9, the oil filled in the oil supply pipe 12 flows backward rather than being pushed up to the rotary shaft 4 so that the oil flows back into the oil pumping chamber ( 9) there was a problem that acts as a fluid resistance to prevent inflow.
또한, 급유관(12)을 통하여 회전축(4)에 형성된 축구멍(11)내에 급유된 오일도 축구멍(11)에 형성된 급유구멍(13)을 통하여 압축부(15)의 습동부에 전달되기 까지 축구멍(11)내의 오일점도와 회전축(4)의 회전력에 의존하여 공급되므로 적절할 오일급유량이 확보되지 못한 경우와 오일 점도가 불량한 경우, 또한 횡형 압축기의 인버터화에 따른 저속운전시에 발생하는 오일의 오일 급유량의 부족에 따른 압축부(5)의 습동부에 충분한 오일이 급유되지 못하는 문제점이 있다.In addition, the oil lubricated in the shaft hole 11 formed in the rotary shaft 4 through the oil supply pipe 12 is also transmitted to the sliding part of the compression unit 15 through the oil supply hole 13 formed in the shaft hole 11. It is supplied depending on the oil viscosity in the shaft hole 11 and the rotational force of the rotating shaft 4 until the proper oil supply is not secured, the oil viscosity is poor, and also occurs at low speed operation due to the inverter of the horizontal compressor. There is a problem that sufficient oil is not lubricated in the sliding part of the compression unit 5 due to the lack of oil lubrication amount of the oil.
본 고안은 이러한 점을 감안하여 고안한 것으로서 오일을 펌핑하기 위하여 오일펌핑실내에서 왕복운동하는 베인에 의하여 흡입 또는 토출되는 오일이 역류되는 오일이 역류되는 것을 방지하는 역류방지수단을 구성하고, 상기 오일펌핑실에서 토출되어 회전축에 형성된 축구멍내로 유입된 오일이 급유구멍을 통하여 압축부의 습동부에 원활하게 급유되도록 하는 급유수단을 구비함으로써 급유가 원활하게 이루어지도록 하는데 목적이 있다.The present invention has been devised in view of the above, and constitutes a backflow prevention means for preventing the oil backflowing of the oil sucked or discharged by the vane reciprocating in the oil pumping chamber to backflow the oil to pump oil, It is an object of the present invention to provide smooth oil supply by providing oil supply means for smoothly oiling the sliding part of the compression part through the oil supply hole discharged from the pumping chamber and introduced into the shaft hole formed in the rotating shaft.
본 고안 횡형 압축기의 급유장치를 제 3 도에 의하여 설명한다.The oil supply apparatus of the present invention horizontal compressor will be described with reference to FIG.
회전축(101)의 회전구멍에 의하여 회전운동을 하는 롤러(102)와 상기 롤러(102)의 회전운동에 의하여 압축하는 압축부(103)와, 상기 롤러(102)의 회전운동과 스프링(104)의 탄성력에 의하여 왕복운동을 하는 베인(105)과 상기 베인(105)이 왕복운동하는 오일펌핑실(106)로 흡입되었다가 토출되어 급유하는 급유관(107)과 상기 급유관(107)을 통하여 회전축(101)에 형성된 축구멍(108)으로 유입된 오일이 압축부(103)의 습동부로 오일을 급유하는 급유구멍(109)을 형성한 것에 있어서,The roller 102 which rotates by the rotation hole of the rotating shaft 101, the compression part 103 compressed by the rotational movement of the roller 102, the rotational movement of the roller 102, and the spring 104. Through the oil supply pipe 107 and the oil supply pipe 107 which are sucked into the oil pumping chamber 106 which is reciprocated by the elastic force of the vane 105 and the vane 105 is reciprocated and discharged. In the case where the oil flowing into the shaft hole 108 formed in the rotating shaft 101 forms the oil supply hole 109 for supplying oil to the sliding part of the compression part 103,
상기 베인(105)의 왕복운동에 따라 흡입 또는 토출되는 오일이 역류되는 것을 방지하는 역류방지수단과, 상기 오일펌핑실(106)에서 토출되어 회전축(101)에 형성된 축구멍(108)내로 유입된 오일이 급유구멍(109)을 통하여 압축부(103)의 습동부에 원활하게 급유되도록 하는 급유수단을 구비하였다.Backflow preventing means for preventing backflow of the oil sucked or discharged according to the reciprocating motion of the vane 105 and discharged from the oil pumping chamber 106 and introduced into the shaft hole 108 formed in the rotating shaft 101 Oil supply means was provided to smoothly supply oil to the sliding part of the compression section 103 through the oil supply hole 109.
상기 역류방지수단은 베인(105)의 왕복운동에 따라 오일이 흡입되는 흡입부(115)에 다단으로 형성한 유체다이오드(110)(110')와, 상기 유체다이오드(110)(110')의 사이에 오일이 역류되는 것을 방지하도록 형성한 역류방지판(111)과, 상기 베인의 왕복운동에 따라 흡입된 오일이 토출되는 토출부(116)에 다단으로 형성한 유체다이오드(112)(112')와, 상기 유체다이오드(112)(112')의 사이에 오일이 역류되는 것을 방지하도록 형성한 역류방지판(113)을 구비하였다.The backflow preventing means includes a plurality of fluid diodes 110 and 110 ′ formed in multiple stages on the suction part 115 where oil is sucked in accordance with the reciprocating motion of the vane 105, and the fluid diodes 110 and 110 ′ of the fluid diodes 110 and 110 ′. The backflow preventing plate 111 formed to prevent oil from flowing back between the fluid diodes 112 and 112 'formed in multiple stages in the discharge part 116 through which the sucked oil is discharged according to the reciprocating motion of the vanes. ) And a backflow preventing plate 113 formed to prevent oil from flowing back between the fluid diodes 112 and 112 '.
그리고, 상기 급유수단은 급유관(107)을 통하여 축구멍(108)내로 유입된 오일의 이송이 원활하여지도록 나선홈(114)을 구비하였다.In addition, the oil supply means has a spiral groove 114 to smoothly transfer the oil introduced into the shaft hole 108 through the oil supply pipe 107.
이와 같이 구성된 본 고안의 작용효과를 제 3 도에 의하여 설명한다.The effect of the present invention configured as described above will be described with reference to FIG.
압축기를 가동시키면 회전축(101)이 회전함에 따라 롤러(102)가 회전운동을 하면서 압축부(103)가 압축된다.When the compressor is operated, the compression unit 103 is compressed while the roller 102 rotates as the rotary shaft 101 rotates.
그리고, 롤러(102)의 회전운동과 스프링(104)의 탄성력에 의하여 베인(105)이 왕복운동을 하게 된다.In addition, the vane 105 is reciprocated by the rotational motion of the roller 102 and the elastic force of the spring 104.
따라서, 상기 베인(105)의 작동에 따라 오일이 오일펌핑실(106)로 흡입되는데, 이때 오일은 유체다이오드(110)을 통하여 흡입부(115)로 흡입된 다음 역류방지판(111)과 유체다이오드(110')를 통하여 오일펌핑실(106)내로 흡입된다.Therefore, the oil is sucked into the oil pumping chamber 106 according to the operation of the vane 105, where the oil is sucked into the suction unit 115 through the fluid diode 110 and then the fluid is prevented from the backflow prevention plate 111. It is sucked into the oil pumping chamber 106 through the diode 110 '.
그리고, 상기 오일펌핑실(106)로 흡입된 오일은 유체다이오드(112)를 통하여 토출부(116)내로 토출되고 상기 토출부(116)로 유입된 오일은 역류방지판(113)과 유체다이오드(112)를 통하여 급유관(107)으로 급유된다.In addition, the oil sucked into the oil pumping chamber 106 is discharged into the discharge unit 116 through the fluid diode 112, and the oil introduced into the discharge unit 116 includes the backflow preventing plate 113 and the fluid diode ( Oil is supplied to the oil supply pipe 107 through 112.
이와 같이 오일이 흡입부(115)내의 역류방지판(111)과 토출부(116)내의 역류방지판(113)에 의하여 역류가 되지 아니하기 때문에 유체저항을 크게 받지 않게 됨으로 인하여 급유효율이 높아진다.In this way, since the oil does not flow back by the backflow prevention plate 111 in the suction part 115 and the backflow prevention plate 113 in the discharge part 116, the oil supply efficiency is increased because the fluid resistance is not largely received.
그리고, 상기 급유관(107)으로 급유된 오일은 회전축(101)내의 축구멍(108)으로 유입되는데, 이때 축구멍(108)에 나선홈(114)이 형성되어져 있기 때문에 회전축(101)의 회전력이 인버터화에 따른 저속운전시 작아지거나 급유관(107)를 통한 오일의 공급량이 충분하지 못한 경우에도 오일의 운동을 원활하게 해 줌으로써 급유구멍(109)을 통하여 압축부(103)의 습동부에 오일공급이 원활하여진다.In addition, the oil lubricated by the oil supply pipe 107 flows into the shaft hole 108 in the rotation shaft 101. At this time, since the spiral groove 114 is formed in the shaft hole 108, the rotational force of the rotation shaft 101 is increased. In the low speed operation of the inverter, even if the amount of oil supplied through the oil supply pipe 107 is not sufficient, the oil movement is smoothly performed in the sliding part of the compression part 103 through the oil supply hole 109. Oil supply is smooth.
따라서, 습동부의 신뢰성을 한층 향상시킴으로 인하여 압축기의 작동이 원활해지는 유용한 고안이다.Therefore, it is a useful design to smooth the operation of the compressor by further improving the reliability of the sliding part.
