1. High ambient temperature causes high temperature to screw air compressor, which mainly affects air compressor from two aspects. A: The higher the temperature is, the thinner the air is (as if the air compressor is inefficient in Plateau area), which results in the decrease of the working efficiency of the air compressor, makes the air compressor in loading state for more time, carries more load, causes the heat generated by the air compressor to be more, and the sure temperature of the air compressor will be higher. B: When the air compressor is designed, there is a design operating environment temperature (30-40 degrees). Under the design operating environment temperature, the Zui high temperature of the air compressor is close to the protection temperature of the air compressor. If the ambient temperature of the air compressor is higher than the design operating environment temperature, the temperature of the air compressor will be increased, so that the air compressor will end up even exceeding the shutdown temperature of the air compressor. Air compressor high temperature.



二、空(kong)壓機系(xi)統缺油(you)。可檢查(chá)油氣桶(tong)油位，在(zai)停機洩(xie)壓後，潤(run)滑油處(chù)于靜态(tai)時，油位(wèi)應比高(gao)油位标(biao)志H（或MAX）略(luè)高。在設(she)備運行(háng)過程中(zhong)，油位不(bu)能低于(yu)低油位(wei)标志L（或(huo)MIX）。如發現(xiàn)油量不(bu)足🧡或觀(guān)察不到(dao)油位時(shi)，應立即(ji)停車加(jia)油

2. Oil shortage in air compressor system. The oil level of oil and gas barrel can be checked. When the lubricant is static after shutdown and pressure relief, the oil level should be slightly higher than the high oil level mark H (or MAX). During the operation of the equipment, the oil level should not be lower than the low oil level mark L (or MIX). Stop and refuel immediately if insufficient oil is found or no oil level is observed.



三、油(yóu)停止閥(fa)（斷油閥(fá)）工作不(bu)正常。油(you)停止閥(fá)一般為(wei)🏃🏻‍♂️兩位兩(liang)通常閉(bì)電磁閥(fá)，起動時(shi)開啟，停(tíng)機時關(guan)閉，（atlascopco機器(qì)為機械(xie)式開啟(qǐ)閥）以避(bì)免停機(jī)時油氣(qì)桶内的(de)油🧑🏾‍🤝‍🧑🏼繼續(xu)噴入機(jī)頭❓，并從(cóng)進氣口(kǒu)噴出。若(ruo)該元件(jiàn)加載時(shí)不開啟(qi)，主🔴機會(huì)因缺油(yóu)迅速升(shēng)溫，嚴重(zhong)者會造(zao)成螺杆(gan)總成燒(shao)毀。

3. Oil stop valve (oil shut-off valve) works abnormally. Oil stop valves are usually two or two normally closed solenoid valves, which are opened at start and closed at shutdown (atlascopco machine is mechanical open valve) to avoid oil in the oil and gas barrel continuing to inject into the nose and eject from the intake port during shutdown. If the component is not opened when loading, the main engine will be heated rapidly due to oil shortage, and the screw assembly will be burnt down in serious cases.



四、機(ji)油過濾(lü)器問題(tí)A:機油過(guo)濾器堵(du)塞旁通(tong)閥又不(bú)開啟會(hui)造成空(kōng)壓機油(you)不能到(dào)達機頭(tou)，主機會(huì)因缺油(yóu)迅💞速升(sheng)溫。B:機油(yóu)過濾器(qi)堵塞流(liu)量變小(xiǎo)，有一種(zhǒng)情況就(jiu)是空壓(ya)機因為(wei)熱量帶(dài)走的不(bu)是很完(wan)全空壓(yā)機溫度(dù)慢慢升(shēng)高形成(cheng)高溫，另(ling)💋外一種(zhǒng)情況是(shì)空壓機(ji)卸載後(hòu)空壓機(ji)高溫，因(yīn)🔞為空壓(ya)機在加(jiā)載是内(nei)部油壓(ya)高，空壓(yā)✔️機油可(kě)以通過(guo)，而🚶空壓(ya)機卸載(zai)後空壓(yā)🥵機油壓(yā)力低空(kong)壓🌏機油(you)通過空(kong)壓機機(ji)油過濾(lǜ)器困難(nán)，流量太(tai)小從而(ér)造成空(kōng)壓機高(gao)溫。

4. Oil filter problem A: If the oil filter blockages the bypass valve and does not open, the air compressor oil will not reach the engine head, and the main engine will be heated rapidly due to oil shortage. B: The blocking flow of oil filters becomes smaller. One case is that the air compressor temperature rises slowly because the heat takes away from the air compressor. The other case is that the air compressor temperature rises slowly after unloading, because the internal oil pressure of the air compressor is high, and the air compressor oil can pass through, while the air compressor oil pressure of the low air compressor oil passes through the air compressor after unloading. The oil filter is difficult and the flow rate is too small to cause the high temperature of the air compressor.



五、熱(rè)控閥（溫(wēn)控閥）工(gong)作失靈(líng)。熱控閥(fa)安裝于(yú)油冷卻(que)器前方(fāng)，其作用(yong)是維持(chí)機頭排(pái)氣溫度(du)于壓力(lì)露點以(yǐ)上。其工(gong)作原理(li)是剛開(kai)機時由(you)于油溫(wēn)較低，熱(rè)控閥支(zhī)路開啟(qǐ)，主回路(lù)關閉，潤(rùn)滑油不(bú)經冷卻(que)器直接(jiē)噴入機(jī)頭；待溫(wēn)度升至(zhì)40℃以上，熱(rè)控閥逐(zhu)漸關閉(bi)，油同時(shí)從冷卻(què)器和支(zhī)路流過(guo)；升高到(dào)80℃以上，該(gāi)閥完全(quan)關🆚閉，潤(rùn)滑油則(ze)全🆚部經(jīng)冷卻器(qì)再進入(rù)機頭，以(yǐ)zui大程度(du)對潤滑(huá)油⚽進行(hang)冷卻。如(rú)果熱控(kòng)閥出現(xian)故障，則(zé)潤滑油(yóu)可能不(bú)經冷卻(que)器直接(jie)進入機(ji)頭，從而(ér)❗油溫無(wú)法下降(jiàng)，造成超(chao)溫。其失(shi)靈的主(zhǔ)要🧑🏾‍🤝‍🧑🏼原因(yin)，一是閥(fa)芯上的(de)大小兩(liang)個熱敏(mǐn)彈🙇‍♀️簧疲(pi)勞後彈(dàn)性系數(shu)改變，不(bu)能随溫(wēn)度變化(huà)而正常(chang)動作；二(èr)是♉閥體(ti)磨損，閥(fa)芯卡死(si)或動作(zuò)不到位(wei)而無法(fǎ)正常關(guan)閉。可根(gēn)據情況(kuàng)修複或(huò)更換。

Fifth, thermal control valve (temperature control valve) work failure. The thermal control valve is installed in front of the oil cooler. Its function is to maintain the exhaust temperature of the engine head above the pressure dew point. Its working principle is that when starting the engine, because of the low oil temperature, the branch of the thermal control valve is opened, the main circuit is closed, and the lubricant is directly injected into the engine head without the cooler; when the temperature rises above 40 C, the thermal control valve closes gradually, and the oil flows through the cooler and branch at the same time; when the temperature rises above 80 C, the valve is completely closed, and the lubricating oil enters the engine head again through the cooler to a large extent of zui. Cooling. If the thermal control valve fails, the lubricant may enter the engine head directly without the cooler, thus the oil temperature can not be lowered, resulting in overheating. The main causes of failure are: first, the elastic coefficient of the two thermosensitive springs on the valve core changes after fatigue, and they can not operate normally with the temperature change; second, the valve body is worn, the valve core is stuck or the action is not in place and can not close normally. It can be repaired or replaced according to the situation.



六(liù):檢查油(you)量調節(jiē)器是否(fou)正常（對(duì)于複盛(shèng)等機組(zǔ)有油量(liàng)🌈調節閥(fá)），必要時(shí)可适當(dāng)加大噴(pēn)油量。噴(pen)油量在(zai)設備🔞出(chu)廠時已(yi)調好，一(yī)般情況(kuàng)下不宜(yí)改變。

Sixth: Check whether the fuel quantity regulator is normal (for Fusheng and other units, there are fuel quantity regulator valves), if necessary, properly increase the amount of fuel injection. The fuel injection quantity has been adjusted when the equipment is out of the factory, and should not be changed in general.



七(qi)、機油超(chao)過使用(yong)時間機(jī)油變質(zhi)。流動性(xìng)變差，熱(rè)交換熱(rè)性💰能下(xia)降。造成(chéng)空壓機(jī)機頭的(de)熱量不(bú)能完全(quan)帶走造(zao)成空壓(yā)機高🌐溫(wen)。

7. Oil deteriorates over time. The fluidity becomes worse and the heat exchange performance decreases. The heat of the air compressor head can not be completely taken away, resulting in high temperature of the air compressor.



八、檢查(cha)油冷卻(que)器工作(zuo)是否正(zhèng)常。對水(shui)冷式機(jī)型，可檢(jiǎn)查‼️其進(jin)出口水(shui)管的溫(wen)差，正常(chang)情況下(xia)應為5一(yī)8℃，低于5℃可(kě)能有🆚結(jié)垢或堵(dǔ)塞現🔞象(xiàng)，将會影(yǐng)響冷卻(que)器的換(huàn)熱效率(lǜ)⛱️，并造成(chéng)散熱不(bú)良，此時(shi)可将換(huàn)熱器拆(chai)下後進(jìn)行清洗(xǐ)。

8. Check whether the oil cooler works properly. For water-cooled machines, the temperature difference between the inlet and outlet water pipes can be checked. Normally, the temperature difference between the inlet and outlet water pipes should be 518 (?) C. Scaling or blockage may occur below 5 (?) C, which will affect the heat transfer efficiency of the cooler and cause bad heat dissipation. At this time, the heat exchanger can be removed and cleaned.



九、檢查(cha)冷卻水(shui)人口溫(wen)度是否(fou)過高，水(shuǐ)壓及流(liú)量是否(fǒu)正常，對(duì)于風冷(leng)式機型(xíng)則檢查(cha)環境溫(wen)度是否(fǒu)過高。冷(leng)卻水的(de)入口溫(wen)度一🌍般(bān)不應超(chāo)過35℃，水壓(ya)在0.3一0.5MPA之(zhi)間流量(liang)應不小(xiǎo)于規定(ding)流量的(de)90％。環境溫(wen)度不應(ying)高于40℃。如(rú)果達不(bu)到上述(shù)要求，可(ke)通過安(ān)裝冷卻(que)🌈塔、改善(shan)室内通(tōng)風、加大(dà)😍機房空(kōng)間等辦(bàn)法解決(jue)。還可檢(jiǎn)查冷卻(què)風扇工(gong)作是否(fou)正常。如(ru)有故障(zhang)應進行(hang)檢修或(huo)更換。

9. Check whether the population temperature of cooling water is too high, whether the water pressure and flow rate are normal, and whether the ambient temperature is too high for air-cooled machines. Generally, the inlet temperature of cooling water should not exceed 35 C, and the flow rate between 0.3 MPA and 0.5 MPA should be no less than 90% of the prescribed flow rate. The ambient temperature should not be higher than 40 C. If the above requirements are not met, they can be solved by installing cooling towers, improving indoor ventilation, and increasing room space. It can also check whether the cooling fan works properly. If there is a fault, it should be repaired or replaced.



十(shi)、風冷機(jī)組主要(yào)檢查進(jìn)出油溫(wen)相差是(shì)否在10度(du)左右✊，如(rú)果小🤞于(yú)這個值(zhí)則應檢(jian)查散熱(re)器表面(mian)翅片是(shi)否髒堵(dǔ)，如果髒(zāng)堵可🌏用(yong)潔淨空(kong)氣将散(san)熱器表(biao)面粉塵(chen)，并檢查(chá)散熱器(qi)翅片🔱是(shì)否腐蝕(shí)，腐蝕厲(li)害的話(huà)則有必(bì)要考慮(lü)更換散(sàn)✍️熱器總(zong)成🆚，内部(bù)管道是(shì)否有髒(zāng)堵現象(xiàng)，若有此(cǐ)現象則(zé)可用循(xun)環泵循(xún)環帶一(yī)定酸性(xìng)藥水清(qīng)洗🔴，一定(dìng)要注意(yi)藥水濃(nong)度，以及(ji)循環🔞時(shi)間，避免(miǎn)散熱器(qi)因藥水(shuǐ)腐蝕造(zao)成散熱(re)器穿腔(qiāng)。

10. Air-cooled units mainly check whether the difference of oil temperature between inlet and outlet is about 10 degrees. If the difference is less than this value, they should check whether the fins on the radiator surface are dirty blocked. If dirty blocked can be used clean air to dust the radiator surface, and check whether the fins of the radiator are corroded. If the corrosion is serious, it is necessary to consider replacing the radiator assembly and whether the internal pipeline is dirty blocked. The circulating pump can be cleaned with certain acidic medicinal water. The concentration of medicinal water and the circulating time must be paid attention to so as to avoid the radiator perforating due to the corrosion of medicinal water.
