一(yī)、環境溫度過(guo)高對螺杆空(kōng)壓機造成高(gāo)溫這個主要(yào)從二個方面(mian)來影響空壓(yā)機。A:溫度越高(gao)，空氣越是稀(xi)薄（就好象空(kong)🐪壓機在高🏒原(yuan)地區效率低(di)一樣），造成空(kōng)壓機工作效(xiao)率下降，使空(kong)壓機更多時(shi)間處于加載(zǎi)狀态，帶更多(duō)負載，造成空(kōng)壓🏃機産生的(de)熱量更多♍，空(kong)壓機肯定溫(wen)度就更高。B:一(yi)般空壓機設(shè)計的時候就(jiù)有一個設計(jì)運行環境溫(wen)度（30-40度），在設計(jì)運行環境溫(wen)度下運行空(kong)壓機一般🧡zui高(gao)溫度就🔴快接(jie)近空壓機保(bao)💚護溫度，如果(guǒ)空壓機環境(jing)溫度高于設(shè)🌍計運行環❤️境(jing)溫度，就會提(ti)高空壓機的(de)溫度從而使(shǐ)空壓機到底(di)甚至超過空(kong)壓機的停機(ji)溫度，從而造(zao)成空壓機高(gāo)溫。

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、空壓機(ji)系統缺油。可(ke)檢查油氣桶(tong)油位，在停機(ji)洩🙇🏻壓🈚後，潤滑(huá)油處于靜态(tài)時，油位應比(bi)高油位标志(zhi)H（或MAX）略高。在設(she)備運行過程(cheng)中✌️，油位不能(neng)低于低油位(wei)标志L（或MIX）。如🌐發(fa)現油🏃🏻‍♂️量不足(zú)或觀察🌈不到(dào)油位時，應立(li)即停車加油(yóu)

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、油停止閥(fá)（斷油閥）工作(zuo)不正常。油停(ting)止閥一般為(wei)兩位💋兩通常(chang)🏃‍♂️閉電磁閥，起(qǐ)動時開啟，停(tíng)機時關閉，（atlascopco機(ji)器為🔞機械式(shì)開啟閥）以避(bi)免停機時油(yóu)氣桶内的油(yóu)繼續噴入機(jī)頭，并從進氣(qi)口噴出。若該(gāi)元件加載時(shí)💃不開啟，主機(ji)會因缺油迅(xun)速升溫，嚴重(zhòng)者會造成螺(luó)杆總成燒毀(huì)。

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、機油過濾(lǜ)器問題A:機油(yóu)過濾器堵塞(sai)旁通閥又不(bu)開啟會造♋成(chéng)空壓機油不(bu)能到達機頭(tóu)，主機會因缺(quē)油迅速升溫(wen)。B:機油過濾器(qi)堵塞流量變(bian)小，有一種情(qing)👄況就是空壓(yā)機因為熱量(liàng)帶走的不是(shì)很完全空壓(ya)機溫度慢慢(man)升高形成高(gāo)溫，另外一種(zhong)情況是空壓(yā)機卸載後空(kōng)壓機高溫，因(yīn)為空壓機在(zai)加載是内部(bù)油壓高，空壓(ya)機油可以通(tong)過，而空壓機(ji)卸載後空壓(ya)機油壓力低(dī)空壓機油通(tong)☎️過空壓機♊機(ji)油過濾器困(kun)難，流量太小(xiǎo)從而造成空(kōng)壓機高溫。

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(wu)、熱控閥（溫控(kòng)閥）工作失靈(líng)。熱控閥安裝(zhuāng)于油冷卻器(qi)前方，其作♻️用(yòng)是維持機頭(tóu)排氣溫度于(yú)壓力露點以(yi)上。其工🐇作原(yuán)理是剛開機(jī)時由于油溫(wēn)較低，熱控☔閥(fá)支路開啟，主(zhǔ)回路關閉，潤(run)滑⭕油不經冷(lěng)卻器直接⁉️噴(pen)入機頭☎️；待溫(wēn)度升至40℃以上(shang)，熱控閥逐漸(jian)關閉，油同時(shí)從冷卻器🐪和(he)支路流過；升(shēng)高到80℃以上🔞，該(gai)閥完全關閉(bì)，潤滑油則全(quán)部經冷卻器(qi)再進入機頭(tou)，以zui大程度✊對(dui)潤滑油進行(hang)冷卻。如果熱(re)控閥出現故(gu)障，則潤滑油(yóu)可能不經冷(leng)卻器直接進(jin)入機頭，從而(er)油溫無法下(xià)降，造成超溫(wēn)。其失靈⁉️的主(zhu)要原因，一是(shì)閥芯📱上的大(dà)小兩個熱敏(mǐn)彈簧疲勞後(hòu)彈性系數改(gai)⭕變，不能随溫(wen)度變化而正(zheng)常動作；二是(shi)閥體磨損，閥(fá)芯卡死或動(dong)作不到位而(ér)無法正常關(guān)閉。可㊙️根據情(qíng)況修複或🐪更(geng)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:檢查油(yóu)量調節器是(shi)否正常（對于(yu)複盛等機組(zǔ)有油量調🐉節(jiē)閥），必要時可(ke)适當加大噴(pēn)油量。噴油量(liàng)在設備出廠(chang)時已調好，一(yī)般情況下不(bu)宜改變。

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、機(ji)油超過使用(yòng)時間機油變(bian)質。流動性變(biàn)差，熱交🌈換熱(re)💘性⛱️能下降。造(zào)成空壓機機(jī)頭的熱量不(bú)能完全帶走(zou)造成空壓機(ji)高溫。

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)油冷卻器工(gong)作是否正常(cháng)。對水冷式機(jī)型，可💰檢查其(qi)進出口水管(guǎn)的溫差，正常(chang)情況下應為(wéi)5一8℃，低于5℃可能(neng)有✏️結垢或堵(du)塞現象，将會(huì)影響冷卻器(qi)的換熱效率(lü)💃，并造成散熱(re)不良，此時可(ke)将換熱器拆(chai)下後進行清(qīng)洗。

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、檢查冷(leng)卻水人口溫(wen)度是否過高(gao)，水壓及流量(liàng)是否正常，對(duì)于風冷式機(jī)型則檢查環(huan)境溫度是否(fou)過高。冷卻水(shuǐ)🐕的入口溫度(du)一般不應超(chao)過35℃，水壓在0.3一(yī)0.5MPA之間流量應(yīng)不小‼️于規定(ding)流量的90％。環境(jìng)溫度不應高(gao)于40℃。如果達不(bú)到上述要求(qiu)，可通過安裝(zhuāng)冷卻塔、改善(shan)室内通風、加(jia)大機房空間(jian)等辦法解決(jue)。還可檢查冷(lěng)卻㊙️風扇工作(zuo)是否正常。如(rú)有故障應進(jìn)行檢修或更(gèng)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、風冷機(jī)組主要檢查(cha)進出油溫相(xiang)差是否在10度(dù)左右🈚，如♻️果🏃小(xiǎo)于這個值則(zé)應檢查散熱(re)器表面翅片(piàn)是否髒堵，如(ru)果髒堵可用(yòng)潔淨空氣将(jiāng)散熱器表面(miàn)粉塵，并檢查(cha)散熱✨器翅片(piàn)是否腐蝕，腐(fu)蝕☁️厲害的話(huà)則有必要考(kǎo)慮更換散熱(re)器總成，内部(bu)管道是否有(yǒu)髒🧑🏾‍🤝‍🧑🏼堵現象，若(ruò)有此現象則(zé)可㊙️用循環泵(beng)循環帶一定(dìng)酸性藥水清(qīng)洗，一定要注(zhù)意藥水👈濃度(dù)，以及循環時(shi)間，避免散熱(rè)器因藥水腐(fǔ)蝕🔴造成散熱(rè)器穿腔。

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.
