15、ir end housing, which is called air end, sliding into the oil-air tank. Integrative design of air end and oil-air tank makes the structure compact to suit the narrow mounting space on locomotives. Some components are designed on the oil-air tank, such as oil-air separator, filter, controlling parts,

Compressor screw group consists of a couple of mating helical grooved rotors with an asymmetrical mesh profile and turning inside a grey cast

21、iron housing. Air intake is radial, air outlet axial through special shaped opening in the housing of compressor block. 圖3機(jī)頭工作原理Fig.3 Air end working principle1.陰螺桿 Female rotor2.陽螺桿 Male rotor當(dāng)轉(zhuǎn)子旋轉(zhuǎn)時，葉片之間的空氣體積連續(xù)地變化。當(dāng)入口打開時，空氣被吸入。當(dāng)出入口都被轉(zhuǎn)子關(guān)閉時，空氣被壓縮，同時向出口運(yùn)動。當(dāng)轉(zhuǎn)子繼續(xù)旋轉(zhuǎn)，其后打開出口時，壓縮空氣就以最終的壓力被排出。注入空氣壓縮機(jī)內(nèi)的油分別在轉(zhuǎn)子

22、的葉片間嚙合處和轉(zhuǎn)子的葉片與殼體接觸處將轉(zhuǎn)子之間和轉(zhuǎn)子與殼體之間密封并分隔開。另外，油還將壓縮作用產(chǎn)生的熱量吸收并帶走。The volume of air between the lobes changes continuously as the rotors turn. When the inlet port is open, air is aspirated. When both ports are covered by the rotors, the air is compressed and moved towards the outlet. When the rotors final

23、ly clear the outlet port, the compressed air is expelled at its ultimate pressure as the rotors continue turning. Oil is injected into the compressor to seal off the rotor lobes at their mating points and at their points of contact with the housing. This oil additionally absorbs and carries off most

24、 of the heat generated by compression. u 氣路系統(tǒng)流程（見圖2）Air flow(see fig.2)外界空氣由空氣濾清器(5)濾去塵埃后，經(jīng)進(jìn)氣閥(6)到機(jī)頭吸氣口進(jìn)入機(jī)體(1)壓縮室，壓縮機(jī)內(nèi)的一對轉(zhuǎn)子由電機(jī)驅(qū)動旋轉(zhuǎn)，潤滑油因壓力差噴入，此時油與氣混合，油氣混合物被壓縮后從排氣口噴向油氣筒(7)的檔流板進(jìn)行一次機(jī)械油氣分離。由于油氣混合物在較大的油氣筒中突降流速，被筒內(nèi)擋流板折擋后改變氣體運(yùn)動方向時，由于空氣混合的油分較重，凝聚的液相油被沉降在油氣筒底部，這時油氣混合的壓縮氣體僅含有少量未被分離的油。經(jīng)油氣分離器(8)二次分離后，純凈的壓縮空氣經(jīng)壓力

25、維持閥(9)被送至后冷卻器(10)，冷卻后的壓縮空氣送入使用系統(tǒng)中。Fresh air passes through air filter (5) via intake valve (6) to enter compress chamber(1) of the compressor, here air has been compressed and mixed with lubricating oil, then sent into to the oil-air tank (7). After that the compressed air passes through oil separat

26、or (8), minimum pressure valve (9) and the passage of after-cooler (10). At last it is delivered into users system. 各組件功能說明：Function of each component in air system: 圖4空氣濾清器結(jié)構(gòu)圖Fig.4 Structure of air filter 1防塵罩Dust cover2防塵罩卡Dust cover clip3濾芯Filter element4固定支架Fastening supporter5壓扣Pressing clip6支架

27、Supporter. 空氣濾清器（見圖4）Air filter（see Fig.4）空氣濾清器包括濾芯和殼體，濾芯為一干式紙質(zhì)過濾器，如圖4所示。同時，在螺桿空氣壓縮機(jī)上裝有一真空指示器，真空指示器連接處用耐油硅酮密封膠（型號HZ-1213B）密封。指示器顯示紅色或箭頭指向5.0kPa時，應(yīng)更換濾清器芯和倒掉后蓋內(nèi)塵土。重新裝上空濾器后，按下指示器頂端的復(fù)位按鈕復(fù)位。The element of air filter is of dry type paper, See Fig. 4. On the intake seat of the air filter, there is a vacuum

28、 indicator (18), space between a vacuum indicator and intake valve is sealed with Oil-resistant silicone sealant (type HZ-1213B). In case the indicator shows red color or its hand directs to 5kPa, you should replace the filter element and clean the dust in the shell immediately. Then press the top o

29、f the indicator to reset it ( Press To Reset) after reinstalling air filter . 進(jìn)氣閥（見圖5）Intake valve（see Fig.5）該進(jìn)氣閥專門用于間歇工作的螺桿空氣壓縮機(jī)，螺桿空氣壓縮機(jī)工作時，其閥板打開，提供風(fēng)源；當(dāng)其停止工作時，閥板關(guān)閉，使油氣筒內(nèi)含油氣體不能通過，同時其卸壓閥工作，油氣筒內(nèi)壓力在很短時間內(nèi)降到300kPa以下，以免壓縮機(jī)帶壓啟動。主要由兩部分組成（結(jié)構(gòu)見圖5）。This intake valve is specially designed for air compressor whic

30、h works intermittently. When compressor works, the valve plate opens allowing air pass through; when compressor is shut down, the valve plate closes the air passage and at the same time its release section acts and makes the pressure in the oil-air tank reduce to below 300kPa in a very short time, t

31、hus preventing the compressor starting under high back pressure.圖5進(jìn)氣閥結(jié)構(gòu)示意圖Fig.5 structure of intake valve1進(jìn)氣閥體Intake Valve body2卸荷噴嘴Release nozzle3密封墊片Seal washer4墊圈Washer5螺母Nut6螺釘Screw7進(jìn)氣閥閥板Valve board8進(jìn)氣彈簧Intake spring9進(jìn)氣閥閥座Valve seat10擋圈Locking ring11卸荷氣缸Release cylinder12O型圈O-ring13O型圈O-ring14卸荷

33、ct of spring force. Then the intake passage is cut off to prevent the air mixed with oil from exhausting to atmosphere out of oil-air tank. At the same time, it will also prevent the back flow of compressed air from causing the compressor reverse turn. · 卸壓閥 Release valve 當(dāng)壓縮機(jī)停機(jī)后，該閥能在很短時間（14s）內(nèi)

34、將油氣筒內(nèi)的壓力卸至300kPa以下，以保證螺桿空氣壓縮機(jī)在低負(fù)荷下再次啟動，有利于電機(jī)長期地正常工作。When the compressor stops，the release valve can release the pressure of the oil-air tank to a value below 300kPa within a very short period of time(less than 14s), which ensures that the compressor can restart at low pressure and bring benefit to e

35、xtending the service life of motor. . 溫度開關(guān) Temperature switch(14)在失油、油量不足、冷卻不良等情況下，均可能導(dǎo)致排氣溫度過高。當(dāng)排氣溫度達(dá)到溫度開關(guān)所設(shè)定之溫度值時，則溫度開關(guān)斷開而停機(jī)。檢查溫度開關(guān)時，拔下溫度開關(guān)上的電線護(hù)套，用電阻表測量溫度開關(guān)兩接線柱間的電阻，在溫度沒有達(dá)到斷開時，該電阻應(yīng)為0。When there is a lack of oil or no effective cooling offered by the after cooler, the temperature of exhausted air wi

36、ll be overhigh. In case the temperature of the air-oil tank reaches its preset value, the temperature switch will open and the compressor will stop. When to check temperature switch, first move away the wire protect sleeve of the temperature switch, then measure the resistance between the two poles

37、of the switch with ohmmeter. If the temperature switch is not open, the value of the resistance is 0. . 油氣筒 Oil-air tank(7)油氣筒筒側(cè)裝有視油鏡（見圖6），用來觀察潤滑油油位，螺桿空氣壓縮機(jī)停機(jī)10分鐘后觀察，油位應(yīng)在視油鏡的上限與下限之間。油氣筒下方裝有泄油閥，定期打開泄油閥以排除油氣筒內(nèi)的凝結(jié)水，筒上方裝有加油孔可供加油用。由于油氣筒的特殊設(shè)計，可使壓縮空氣中的較大油滴與空氣分離，此為初級油氣分離。There is a sight glass (15) on both

38、sides of oil-air tank.( see Fig. 6). After the compressor stops for 10mins, check lubricating oil through the sight glass, the oil level should be within up and low limits. At the lower corner of air-oil tank there is a drainage valve (16).Periodically open the drain valve to discharge the condensed

39、 water. On the top of the tank there is an oil hole to fill oil. Because of the special construction of the oil-air tank, it can separate the larger oil drops from mixture of oil-air. This is the primary oil-air separation. 圖6視油鏡 Fig.6 sight glass. 油細(xì)分離器 Oil-air separator(8)詳細(xì)內(nèi)容請油路系統(tǒng)流程一節(jié)說明。See oil f

40、low for details. . 安全閥（見圖7）Safety valve（see Fig.7）當(dāng)機(jī)車上的主風(fēng)缸壓力開關(guān)調(diào)節(jié)不當(dāng)或排氣管線上有堵塞現(xiàn)象而致使油氣筒內(nèi)壓力超過安全閥的設(shè)定值時，安全閥即會自動起跳而泄壓，使壓力降至設(shè)定的排氣壓力以下。安全閥于出廠前已經(jīng)過整定（整定值為1250kPa），請勿隨意調(diào)整。In case the pressure switch on the main air reservoir fails to work or jam occurs in pipelines, which makes the pressure in oil-air tank excee

41、ds the setting value of the safety valve. The safety valve will act automatically to reduce the pressure to below set value. The set value of safety valve is adjusted in the factory before delivery. (Set value is 1250 kPa). Do not adjust it without authorization. 圖7安全閥Fig.7 safety valve. 壓力維持閥(見圖8)

42、Minimum pressure valve (9)(see fig.8)此閥位于油氣筒上方油細(xì)分離器出口處，開啟壓力設(shè)定于600±50kPa。壓力維持閥的功能主要為：Minimum pressure valve locates at the outlet of oil separator. Its set open pressure is 600±50 kPa. The main functions of minimum pressure valve are: ·啟動時優(yōu)先建立起潤滑油的循環(huán)壓力，確保機(jī)器的潤滑。Build up initial circulat

43、ion pressure for the oil to lubricate in the compressor. ·壓力超過600±50kPa后開啟，可降低流過油細(xì)分離器的空氣流速，除確保油細(xì)分離效果之外，還可保護(hù)油細(xì)分離器避免因壓差太大而受損。At the pressure of 600±50 kPa minimum pressure valve opens. It can descend the velocity of air flow, ensure the effect of separation and prevent the oil separator

44、 from being damaged because of over pressure difference. ·止回功能：當(dāng)停機(jī)后油氣筒內(nèi)壓力下降時，防止主風(fēng)缸內(nèi)壓縮空氣回流。Check function: When compressor stops and the pressure in the tank reduce rapidly, it plays a function of check valve to prevent back flow of compressed air. 圖8壓力維持閥體 Fig.8 Minimum pressure valve. 壓力開關(guān)（見圖9

45、）Pressure switch（see Fig.9）壓力開關(guān)受進(jìn)氣閥閥座內(nèi)壓力控制，壓縮機(jī)停機(jī)后，油氣筒內(nèi)壓力立即傳至進(jìn)氣閥閥座內(nèi)，壓力開關(guān)斷開。隨著油氣筒內(nèi)的壓力被卸荷閥快速卸除, 進(jìn)氣閥閥座內(nèi)壓力也降低,當(dāng)壓力小于300kPa時，壓力開關(guān)恢復(fù)接通，此時壓縮機(jī)才能再次啟動，保證了電動機(jī)在低負(fù)載下啟動。壓縮機(jī)運(yùn)行時，進(jìn)氣閥腔內(nèi)壓力低于大氣壓力，壓力開關(guān)處于接通狀態(tài)。壓力開關(guān)在出廠前已設(shè)定好，請勿隨意調(diào)整。Pressure switch is controlled by air pressure inside the intake valve seat. Immediately after t

46、he compressor shutdown, the pressure in oil-air tank will transfer to the intake valve seat, and the pressure switch opens. With the rapid reduction of the pressure in air-oil tank caused by release valve, the pressure of inside chamber of intake valve seat reduces to 300kPa, then pressure switch wi

47、ll close and it is possible for the compressor to restart. This performance ensures the compressor can only be started under a low load. When the compressor is running, the pressure of inside chamber of intake valve seat is lower than atmosphere pressure and pressure switch is in close condition. Th

48、e pressure switch has been calibrated before delivery to clients. Dont adjust it without authorization. 圖9壓力開關(guān) Fig.9 pressure switch. 后冷卻器 After cooler(10)風(fēng)機(jī)將冷卻空氣送入后冷卻器，通過后冷卻器冷卻壓縮空氣。The blower sends cooling air to pass through the out surface of the after-cooler, taking the heat from compressed air

49、through the after-cooler.u 油路系統(tǒng)流程 Oil flow潤滑油路系統(tǒng)由油細(xì)分離器、溫控閥、油冷卻器和油過濾器等組成。潤滑油是在無油泵的條件下利用氣壓壓差原理進(jìn)行循環(huán)。Lubricating oil system consists of oil separator, thermal valve, oil cooler and oil filter. The oil flow is driven by the pressure of oil-air mixture inside the tank, no oil pump. 潤滑油流程工作原理： Oil flow wor

50、king principle:由于油氣筒(7)內(nèi)存在壓力，潤滑油從筒內(nèi)流出，經(jīng)過溫控閥 (12)分成二路，當(dāng)溫度低于下限（77）時，直接從旁通路進(jìn)入油過濾器(11)過濾，當(dāng)溫度高于下限（77）時，主通路逐漸打開,部分油到油冷卻器(17)冷卻，油溫高于上限（93）以上時，全部經(jīng)過油冷卻器冷卻后進(jìn)入油過濾器，過濾后的油再分成二路，一路由機(jī)體下部噴入壓縮室，冷卻壓縮空氣、潤滑螺桿；另一路通到主機(jī)兩端，潤滑軸承組；而后匯集于壓縮室，隨壓縮空氣一起進(jìn)入油氣筒(7)。Due to the pressure inside the oil-air tank(7), lubricating oil flows

51、via thermal valve (12) and divides into two directions, when the temperature is lower than its lower limit(77）,it directly flows into oil filter via bypass passage(11); when the temperature is higher than its lower limit（77）, main passage opens gradually and part of oil goes in to oil cooler; when t

52、he temperature is higher than its upper limit（93）, all the oil enters into oil cooler. The oil filtrated divided into two passages: one leads to compressor block bottom to lubricate compressed air and screws; the other one leads to two ends of compressor block to lubricate bearing group. And then al

53、l oil joins together in the compression chamber entering into oil-air tank together with compressed air (7). 油冷卻器 Oil cooler(17)油冷卻器之翅片易受灰塵覆蓋而影響冷卻效果，可能導(dǎo)致排氣溫度過高而停機(jī)。因此每隔一段時間應(yīng)對其進(jìn)行清洗以確保其冷卻效果。Corrugated fins are likely to be covered with dust, which can influence the cooling effect of oil cooler, even po

54、ssibly leads to shutdown due to over high temperature. So it should be cleaned in intervals to ensure its cooling effect. . 油過濾器 （見圖10）Oil filter（見圖10 see Fig.10） 圖10油過濾器Fig. 10 Oil filter油過濾器是一種紙質(zhì)的過濾器，其功能為除去油中之雜質(zhì)，如：金屬微粒、油的劣化物等。以保護(hù)軸承及轉(zhuǎn)子。若油過濾器未及時更換則可能導(dǎo)致進(jìn)油量不足，造成排氣溫度升高，以致停機(jī)；或油過濾器內(nèi)的旁通閥開啟，使臟油未經(jīng)過濾即進(jìn)入壓縮機(jī)內(nèi)，

55、損傷轉(zhuǎn)子、軸承及殼體。在更換油過濾器時，請使用嘉祥公司提供的專用帶式扳手，夾住黑色濾筒上的白色金屬環(huán)，按逆時針方向旋轉(zhuǎn)，拆下舊的油過濾器后，用專用帶式扳手按順時針旋上新的油過濾器。The element of oil filter is of dry type paper. Its function is removing impurity such as metallic particulates, separations from lubricating oil etc. to protect rotors and bearings. If the oil filter is not replaced in time, the flow rate of oil is possibly reduced, leading to over high exhaust temperature or even shutdown. It can also make th
