Description

압축기의 오일보충장치 및 그 방법{APPARATUS AND METHOD FOR REPLENISHING OIL IN A COMPRESSOR}Oil filling device of compressor and its method {APPARATUS AND METHOD FOR REPLENISHING OIL IN A COMPRESSOR}

본 고안은 압축기(compressor)에 관한 것으로써, 더욱 상세하게는 압축기의 구동시 소모되는 오일을 자동으로 보충하는 장치 및 그 방법에 관한 것이다.The present invention relates to a compressor, and more particularly, to an apparatus and a method for automatically replenishing oil consumed when driving a compressor.

일반적으로, 압축기는 크랭크실(crank case)이나 하우징(housing) 내부에 있는 오일로 윤활작용을 일으키며, 이 오일이 압축기의 여러 부분을 순환하게 되는데, 압축기가 구동할 때에는 소량의 오일이 고온, 고압의 압축된 공기와 함께 펌핑되어 나오게 된다.Generally, the compressor is lubricated with oil in the crank case or the housing, which circulates through the various parts of the compressor, where a small amount of oil is hot and high pressure when the compressor is running. It is pumped out with compressed air.

즉, 구동모터에 전원이 인가되면, 구동모터의 구동력은 공기를 흡입하여 압축시키는 압축기구부를 작동시키며, 이에 따라 압축기구부에서는 공기를 흡입하여 압축시킨 후 배출하며, 배출된 압축공기는 산업전반에 걸쳐 사용된다.That is, when power is applied to the drive motor, the driving force of the drive motor operates the compressor mechanism for sucking and compressing air. Accordingly, the compressor mechanism sucks and compresses the air and discharges the compressed air. It is used throughout.

상기한 압축기구부는 상부측이 개구되어 내부에 오일이 채워지는 크랭크실과, 이 크랭크실의 개구부측에 결합되는 실린더와, 이 실린더의 내부에 삽입되어 상하 왕복운동되는 피스톤 등을 포함하며, 피스톤은 구동모터의 구동에 의해 상하로 왕복운동된다.The compressor mechanism includes a crank chamber in which an upper side is opened to fill oil therein, a cylinder coupled to the opening side of the crank chamber, a piston inserted into the cylinder, and a vertically reciprocating motion. It is reciprocated up and down by the drive motor.

이와 같은 피스톤의 상하운동시 윤활작용을 위해 하부의 크랭크실로부터 소량의 오일이 공급되며, 공급된 오일은 실린더와 피스톤 사이의 틈새를 통해 상승하여 압축된 공기와 함께 토출되게 되어, 결국 오랜시간 구동한 경우 크랭크실내의 보유된 오일량이 일정량 이하로 감소됨으로써, 압축기의 소손이나 성능저하가 유발되게 된다.A small amount of oil is supplied from the lower crank chamber for lubrication during the vertical movement of the piston, and the supplied oil rises through the gap between the cylinder and the piston and is discharged together with the compressed air. In one case, the amount of oil retained in the crankcase is reduced to a certain amount or less, thereby causing the compressor to burn out or degrade the performance.

따라서, 종래에는 압축기의 구동에 앞서 크랭크실 등에 구비된 점검창을 통해 오일레벨을 확인하고, 오일레벨이 낮은 경우에는 수동으로 필요량을 보충하게 되는데, 이에 따른 불편함이 상존하였다.Therefore, conventionally, prior to driving the compressor, the oil level is checked through a check window provided in a crank chamber, etc., and when the oil level is low, the required amount is manually supplemented.

본 고안은 상기와 같은 제반 문제점을 해결하기 위하여 창안된 것으로써, 압축기를 보호함과 동시에 성능향상을 도모하기 위하여 압축기의 구동시간에 따라 자동으로 오일을 보충하는 장치 및 그 방법을 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and to provide an apparatus and a method for automatically replenishing oil according to the running time of the compressor in order to protect the compressor and to improve performance. There is this.

또한, 상술한 목적을 달성하기 위한 본 고안은, 흡입된 공기를 고압으로 압축하여 토출하는 압축기에서 그 구동에 따라 소모되는 오일을 보충하는 방법으로서, 상기 압축기의 시간당 오일소모량으로부터 구해지는 적정 잔존 오일량까지의 한계구동시간까지 구동시간타이머로 구동시간을 적산하는 단계와, 상기 구동시간타이머에서 상기 한계구동시간까지 적산되면, 솔레노이드밸브가 개방되어 보충용 오일탱크로부터 오일공급관을 통해 상기 압축기의 흡입측으로 오일이 공급 보충되는 단계를 포함하는 압축기의 오일보충방법을 제공한다.In addition, the present invention for achieving the above object is a method for replenishing the oil consumed according to the operation of the compressor in the compressed air discharged by compressing the high pressure, appropriate residual oil obtained from the oil consumption per hour of the compressor Integrating the drive time with the drive time timer up to the limit drive time up to the amount, and when the drive time timer is integrated up to the limit drive time, the solenoid valve is opened to the suction side of the compressor through the oil supply pipe from the supplemental oil tank. Provided is an oil replenishment method of a compressor comprising the step of replenishing oil.

본 고안의 상기 목적과 여러가지 장점은 이 기술분야에 숙련된 사람들에 의해 첨부된 도면을 참조하여 아래에 기술되는 고안의 바람직한 실시예로부터 더욱 명확하게 될 것이다.The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

이하, 첨부된 도면을 참조로 본 고안의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 압축기의 오일보충장치에 대한 개략도이다.1 is a schematic diagram of an oil filling apparatus of a compressor according to the present invention.

압축기(10)에는 외부의 공기가 인입되는 인입측(20)과, 인입되어 압축된 공기가 토출되는 토출측(30)의 라인이 구비되며, 압축기(10) 구동시 소량의 오일이 압축된 공기와 함께 토출됨에 따라 장시간 구동되면 압축기(10) 내부에 보유된 오일량이 일정량 이하로 감소되어 오일부족 현상이 유발된다.The compressor 10 includes an inlet side 20 through which external air is introduced, and a line on the discharge side 30 through which incoming and compressed air is discharged, and a small amount of air compressed with a small amount of oil when the compressor 10 is driven. As it is discharged together, when driven for a long time, the amount of oil retained in the compressor 10 is reduced to a predetermined amount or less, causing oil shortage.

이에, 본 고안에 따르면, 소모된 오일을 자동으로 보충하는 오일보충장치(60)가 제공되며, 오일보충장치(60)는 보충용 오일이 저장되는 보충용 오일탱크(70)와, 이 보충용 오일탱크(70)와 압축기(10)의 흡입측(20)을 연결하는 오일공급관(90)과, 이 오일공급관(90)을 개폐하는 솔레노이드밸브(80)를 구비한다.Thus, according to the present invention, there is provided an oil supplement device 60 for automatically replenishing the spent oil, the oil supplement device 60 is a supplementary oil tank 70 in which the supplementary oil is stored, and the supplementary oil tank ( 70 and an oil supply pipe 90 connecting the suction side 20 of the compressor 10 and a solenoid valve 80 for opening and closing the oil supply pipe 90.

이로써, 압축기(10)의 구동시간이 일정시간 이상으로 적산되면, 솔레노이드밸브(80)가 소정시간 작동되어 오일공급관(90)을 개방함으로써 보충용 오일탱크(70)의 오일이 압축기(10)로 유입되어 압축기(10)의 장시간 구동에 따른 오일부족 현상을 미연에 방지하게 된다.Thus, when the driving time of the compressor 10 is accumulated over a predetermined time, the solenoid valve 80 is operated for a predetermined time to open the oil supply pipe 90 so that the oil of the replenishment oil tank 70 flows into the compressor 10. As a result, the oil shortage caused by long-term operation of the compressor 10 is prevented in advance.

도 2는 본 고안에 따른 오일보충장치의 구동제어회로의 일 구성예를 나타낸다.Figure 2 shows an example of the configuration of the drive control circuit of the oil filling apparatus according to the present invention.

도면을 참조하면, 전원(AC)에 연결된 압축기(C)와, 압축기(C)에 전원(AC)을 인가 또는 차단시키는 압축기구동스위치(SW1)와, 압축기(C)와 접속되어 압축기(C)와 동시에 전원(AC)을 인가받아 압축기(C)의 구동시간을 적산하는 구동시간타이머(T1)와, 전원(AC)을 인가받아 오일보충장치(60)의 오일공급관(90)을 개폐하는 솔레노이드밸브(SV)와, 솔레노이드밸브(SV)로의 입력 전원(AC)을 스위칭하는 오일보충스위치(SW2)와, 솔레노이드밸브(SV)와 접속되어 솔레노이드밸브(SV)와 동시에 전원(AC)을 인가받아 솔레노이드밸브(SV)의 작동시간을 계수하는 오일공급타이머(T2)와, 구동시간타이머(T1) 및 오일공급타이머(T2)에 연결되어 솔레노이드밸브(SV)의 오일보충스위치(SW2)의 접점을 소정시간 절환시키는 마이콤(M)이 구비된다.Referring to the drawings, the compressor C connected to the power source AC, the compressor drive switch SW1 for applying or cutting off the power source AC to the compressor C, and the compressor C connected to the compressor C And a solenoid for opening and closing the oil supply pipe 90 of the oil refilling device 60 with a driving time timer T1 for applying the power supply AC to accumulate the driving time of the compressor C, and receiving the power supply AC. Connected to the valve SV, the oil supply switch SW2 for switching the input power AC to the solenoid valve SV, and the solenoid valve SV, the power supply AC is applied simultaneously with the solenoid valve SV. It is connected to the oil supply timer T2 that counts the operation time of the solenoid valve SV, and the drive time timer T1 and the oil supply timer T2 to contact the oil replenishment switch SW2 of the solenoid valve SV. A microcomputer M for switching a predetermined time is provided.

이러한 구동제어회로의 작동을 설명하면, 먼저, 운전자로부터 운전개시신호가 입력되어 압축기구동스위치(SW1)가 온(on)되면, 압축기(C)가 구동된다. 이와 동시에 구동시간타이머(T1)에 의해 압축기(C)의 구동시간이 적산되며, 일정시간 이상으로 적산되면(즉, 압축기(C)의 보유 오일량이 일정량 이하로 되면), 구동시간타이머(T1)에 연결된 마이콤(M)에 의해 오일보충스위치(SW2)의 접점이 솔레노이드밸브(SV)에 전원(AC)이 인가되도록 절환되며, 한편 구동시간타이머(T1)는 초기화된다. 따라서, 솔레노이드밸브(SV)가 작동되어 오일공급관(90)을 통해 보충용 오일탱크(70)의 오일이 압축기(10)의 흡입측(20)으로 유입되며, 이와 동시에 오일공급타이머(T2)가 작동하여 솔레노이드밸브(SV)의 작동시간을 계수하고, 소정시간이 되면, 오일공급타이머(T2)에 연결된 마이콤(M)에 의해 오일보충스위치(SW2)가 오프(off)되어 솔레노이드밸브(SV)의 작동이 멈추며, 오일공급타이머(T2)는 초기화된다.Referring to the operation of the drive control circuit, first, when the operation start signal is input from the driver and the compressor drive switch SW1 is turned on, the compressor C is driven. At the same time, the driving time of the compressor C is accumulated by the driving time timer T1, and when accumulated over a predetermined time (that is, when the amount of oil retained in the compressor C becomes less than a certain amount), the driving time timer T1. The contact point of the oil filling switch SW2 is switched so that the power supply AC is applied to the solenoid valve SV by the microcomputer M connected to the driving unit, while the driving time timer T1 is initialized. Therefore, the solenoid valve (SV) is operated so that the oil of the replenishment oil tank 70 flows into the suction side 20 of the compressor 10 through the oil supply pipe 90, and at the same time, the oil supply timer T2 is operated. Count the operating time of the solenoid valve (SV), and when the predetermined time is reached, the oil replenishment switch (SW2) is turned off by the microcomputer (M) connected to the oil supply timer (T2). Operation stops, and the oil supply timer T2 is initialized.

본 고안에 의하면, 압축기(C) 구동시의 시간당 오일소모량(cc/min)은 이론칙, 실험칙, 경험칙 등으로부터 구할 수 있으므로, 구해진 시간당 오일소모량으로부터 구동시간의 경과에 따른 누적 오일소모량(또는, 잔존 오일량)을 알 수 있어 압축기(C) 구동에 악영향을 미치지 않는 적정 잔존 오일량까지의 한계구동시간을 계산하여, 계산되는 한계구동시간까지 구동시간타이머(T1)는 구동시간을 적산한다.According to the present invention, since the oil consumption per hour (cc / min) at the time of driving the compressor (C) can be obtained from the theoretical, experimental, empirical, etc., the accumulated oil consumption according to the passage of the driving time from the obtained oil consumption per hour (or , The amount of remaining oil is calculated so that the limit drive time to the appropriate amount of remaining oil which does not adversely affect the operation of the compressor C is calculated, and the drive time timer T1 adds the drive time to the calculated limit drive time. .

그리고, 소모된 오일량에 상응하는 양의 오일을 보충해 주어야 하므로, 오일공급관(90)의 구경 등을 감안하여 구해지는 시간당 가능 오일보충량으로부터 필요한 솔레노이드밸브(SV)의 개방시간을 알 수 있어, 이 개방시간까지 오일공급타이머(T2)는 솔레노이드밸브(SV)의 작동시간을 계수한다.In addition, since the oil corresponding to the amount of oil consumed must be replenished, the opening time of the required solenoid valve (SV) can be known from the available oil replenishment amount obtained in consideration of the diameter of the oil supply pipe 90 and the like. To this opening time, the oil supply timer (T2) counts the operating time of the solenoid valve (SV).

이상과 같이, 압축기(C)의 구동에 따라 소모된 오일의 보충을 전자동으로 구현되게 구성할 수 있으나 이와 다르게 일부과정을 작업자의 조작에 의하도록 구성할 수도 있다.As described above, the replenishment of the oil consumed according to the operation of the compressor C may be configured to be implemented automatically, but alternatively, some processes may be configured to be operated by an operator.

즉, 구동시간타이머(T1)에서 기설정된 한계구동시간까지 적산되면, 압축기(C)에서 램프발광 등으로 알람기능이 수행되어 운전자가 이를 인지하고 압축기(C)의 제어판넬 등에 구비된 "오일보충버튼"을 누르면, 솔레노이드밸브(SV)가 소정시간 개방되어 보충용 오일탱크(70)로부터 오일공급관(90)을 통해 오일이 압축기(C)내로 유입되도록 한 후, 운전자가 제어판넬 등에 구비된 "리셋버튼"을 누르면, 구동시간타이머(T1)가 초기화되도록 구성할 수도 있다.That is, when the driving time timer T1 is accumulated up to a predetermined limit driving time, the alarm function is performed by the lamp light emission in the compressor C, and the driver recognizes this and the "oil supplement" provided in the control panel of the compressor C. When the button is pressed, the solenoid valve SV is opened for a predetermined time to allow oil to flow into the compressor C from the replenishment oil tank 70 through the oil supply pipe 90, and the driver is provided with a "reset" provided in the control panel. Button ", the driving time timer T1 may be configured to be initialized.

그리고, 구동시간타이머(T1)에서 기설정된 한계구동시간까지 적산되면, 일단압축기(C)의 구동이 스톱되고, 오일 보충이 완료된 후, 재구동시키도록 구성할 수도 있을 것이다.And, if the integration up to the predetermined limit drive time in the drive time timer (T1), once the drive of the compressor (C) is stopped, it may be configured to restart after the oil replenishment is completed.

한편, 이상에서 타이머(즉, 구동시간타이머(T1))를 이용하여 오일이 일정량이상으로 소모된 시점을 확인하는 것으로 하였으나 이와 다르게 잔존 오일량을 지시하도록 된 오일량 지시 튜브내의 유동되는 플로트(float)의 위치(즉, 한계 잔존 오일량에 대응하는 위치)를 광센서유닛을 이용하여 감지하도록 하고, 이 광센서유닛으로부터의 출력신호에 대응하여 자동 혹은 반자동으로 솔레노이드밸브(SV)가 개방되도록 하여 오일을 보충시키도록 구성할 수도 있을 것이다.On the other hand, the above-mentioned time using the timer (that is, the driving time timer (T1)) to determine the time when the oil is consumed by a certain amount, but the float that flows in the oil amount indicating tube to indicate the remaining oil amount differently ) Position (that is, the position corresponding to the limit residual oil amount) by using the optical sensor unit, and the solenoid valve (SV) is opened automatically or semi-automatically in response to the output signal from the optical sensor unit. It may be configured to replenish oil.

이와 같이, 본 고안에 따른 오일보충장치(60)의 구동제어는 당업자에 의해 여러 형태로 구현 가능하다.As such, the driving control of the oil filling apparatus 60 according to the present invention can be implemented in various forms by those skilled in the art.

덧붙여, 본 고안에 따른 압축기의 오일보충장치(60)는 공압에 의해 작동되는 각종 기계설비나 압축공기 분사기구 등에 연결 설치되는 압축기뿐만 아니라 순환되는 냉매를 고온, 고압으로 압축하는 냉방기기의 압축기 등 산업전반의 압축기에 적용 가능함은 물론이다.In addition, the oil supplement device 60 of the compressor according to the present invention is not only a compressor connected to various mechanical equipment or compressed air injection mechanisms operated by pneumatic pressure, but also a compressor of a cooling device that compresses the circulating refrigerant to high temperature and high pressure. Of course, it can be applied to the compressor of the whole industry.
