一(yi)、環境溫(wen)度過高(gao)對螺杆(gan)空壓機(ji)造成高(gao)溫這個(ge)主要從(cong)二☠️個方(fang)面來影(ying)響空壓(ya)機。A:溫度(du)越高，空(kong)氣越是(shi)稀薄（就(jiu)好象空(kong)💑🏾壓機在(zai)高原地(di)區效率(lü)低一樣(yang)），造成空(kong)壓機工(gong)作效率(lü)下降，使(shi)空壓機(ji)更多時(shi)間處于(yu)加🏊🏾‍♀️載狀(zhuang)态，帶更(geng)多負載(zai)，造成空(kong)壓…機産(chan)生的熱(re)量更多(duo)，空壓機(ji)肯定溫(wen)度就更(geng)高。B:一般(ban)空壓機(ji)🤶🏾設計的(de)時候就(jiu)有一個(ge)設計⛹🏻‍♂️運(yun)行環境(jing)溫度✋（30-40度(du)），在設計(ji)運行⛹🏻‍♂️環(huan)境溫度(du)下運行(hang)空壓機(ji)一般zui高(gao)溫度就(jiu)快接近(jin)空壓機(ji)保護溫(wen)度，如果(guo)空壓機(ji)環境溫(wen)度高于(yu)設計運(yun)行環境(jing)溫度，就(jiu)🤶🏾會提高(gao)空壓🧑🏾‍🎄機(ji)的溫度(du)從而使(shi)空壓機(ji)到底甚(shen)至超過(guo)空壓👾機(ji)的停機(ji)溫度，從(cong)而造成(cheng)空壓機(ji)高溫。

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(er)、空壓機(ji)系統缺(que)油。可檢(jian)查油氣(qi)桶油位(wei)，在停機(ji)洩壓後(hou)，潤滑油(you)處于靜(jing)态時，油(you)位應比(bi)高油位(wei)标志H（或(huo)💫MAX）略高。在(zai)設備運(yun)行過程(cheng)中，油位(wei)不能低(di)于低油(you)位标👀志(zhi)L（或MIX）。如發(fa)現油量(liang)不足或(huo)觀察不(bu)到油位(wei)時，應立(li)即停車(che)加油

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(san)、油停止(zhi)閥（斷油(you)閥）工作(zuo)不正常(chang)。油停止(zhi)閥一般(ban)為兩位(wei)兩通常(chang)閉電磁(ci)閥，起動(dong)時開啟(qi)，停機時(shi)關閉，（atlascopco機(ji)器為機(ji)械式開(kai)啟閥）以(yi)避免停(ting)機時油(you)氣桶内(nei)的油繼(ji)續噴😍入(ru)機頭🛌🏻，并(bing)從進氣(qi)口噴出(chu)。若該💫元(yuan)件加載(zai)時不開(kai)啟，主機(ji)會因缺(que)🧜🏼‍♂️油迅速(su)升🙈溫，嚴(yan)重者✋會(hui)造成螺(luo)杆總成(cheng)燒毀。

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(si)、機油過(guo)濾器問(wen)題A:機油(you)過濾器(qi)堵塞旁(pang)通閥又(you)不開😈啟(qi)🙂‍↕️會造成(cheng)空壓機(ji)油不能(neng)到達機(ji)頭，主機(ji)會因缺(que)油迅速(su)升溫。B:機(ji)👺油過😵‍💫濾(lü)器堵塞(sai)流量變(bian)小，有一(yi)種情況(kuang)就是空(kong)壓機因(yin)為熱🙂‍↕️量(liang)帶走的(de)不是🙂‍↕️很(hen)完全空(kong)壓機溫(wen)度慢慢(man)升高形(xing)成高溫(wen)，另外一(yi)種情況(kuang)是空壓(ya)機卸載(zai)後空壓(ya)機高溫(wen)，因為空(kong)壓機在(zai)加載是(shi)内部🧛🏾‍♀️油(you)壓高，空(kong)壓機油(you)可以通(tong)過，而空(kong)壓機卸(xie)載後空(kong)壓機油(you)壓力👻低(di)空壓機(ji)油通過(guo)空壓機(ji)機油過(guo)濾器困(kun)難，流量(liang)太小從(cong)而造成(cheng)空壓機(ji)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(fa)（溫控閥(fa)）工作失(shi)靈。熱控(kong)閥安裝(zhuang)于油冷(leng)卻🏃🏻‍♀️器前(qian)方，其作(zuo)用是維(wei)持機頭(tou)排氣溫(wen)度于壓(ya)力露點(dian)以上👀。其(qi)工作原(yuan)理是剛(gang)開機時(shi)由于油(you)溫較低(di)，熱控㊙️閥(fa)支路開(kai)啟，主回(hui)路關🧜🏼‍♂️閉(bi)，潤滑油(you)不經冷(leng)卻器直(zhi)接噴入(ru)機頭；待(dai)溫度升(sheng)💞至40℃以上(shang)，熱控閥(fa)逐漸關(guan)閉，油同(tong)😵‍💫時從冷(leng)卻器和(he)支路流(liu)過；升高(gao)到80℃以上(shang)，該閥完(wan)全關🔞閉(bi)，潤滑油(you)則全部(bu)經冷卻(que)器再進(jin)入機頭(tou)，以zui大程(cheng)度對潤(run)滑油🚶🏾‍♀️‍➡️進(jin)行冷卻(que)。如果熱(re)控閥出(chu)👩🏽‍🐰‍👩🏿現故障(zhang)，則潤滑(hua)油可能(neng)不經冷(leng)卻器直(zhi)接進入(ru)機頭，從(cong)而油溫(wen)無法下(xia)降，造成(cheng)超溫。其(qi)失靈👨🏻‍🏭的(de)主要原(yuan)因，一是(shi)閥芯上(shang)的大小(xiao)兩個熱(re)敏彈簧(huang)疲勞後(hou)彈性系(xi)數改變(bian)，不能随(sui)溫度變(bian)化而👩🏽‍🐰‍👩🏿正(zheng)常動作(zuo)；二是閥(fa)體磨損(sun)，閥芯卡(ka)死或動(dong)作不到(dao)位而無(wu)法正常(chang)💁🏼‍♀️關閉。可(ke)根據情(qing)況修複(fu)或更換(huan)。

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(cha)油量調(diao)節器是(shi)否正常(chang)（對于複(fu)盛等機(ji)組有油(you)量調節(jie)閥），必要(yao)時可适(shi)當加大(da)噴油量(liang)。噴油量(liang)在設備(bei)出廠🙉時(shi)已調好(hao)，一般情(qing)況下不(bu)宜改變(bian)。

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、機油(you)超過使(shi)用時間(jian)機油變(bian)質。流動(dong)性變差(cha)，熱交換(huan)熱性能(neng)下降。造(zao)成空壓(ya)機機頭(tou)的熱量(liang)不能完(wan)全帶走(zou)造成空(kong)壓機高(gao)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(jian)查油冷(leng)卻器工(gong)作是否(fou)正常。對(dui)水冷式(shi)機型，可(ke)檢查其(qi)進出口(kou)水管的(de)溫差，正(zheng)常情況(kuang)下應為(wei)5一8℃，低于(yu)5℃可能有(you)結垢或(huo)堵塞現(xian)👩🏿‍❤️‍💋‍👨🏽象，将會(hui)影響冷(leng)卻器的(de)換🧎🏻‍♀️‍➡️熱效(xiao)率，并造(zao)成散熱(re)不良，此(ci)時可将(jiang)換熱器(qi)拆下後(hou)進行清(qing)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(jian)查冷卻(que)水人口(kou)溫度是(shi)否過高(gao)，水壓及(ji)流量是(shi)否正常(chang)，對于風(feng)冷式機(ji)型則檢(jian)查環境(jing)溫度是(shi)否過高(gao)。冷卻水(shui)的入口(kou)溫度一(yi)般不應(ying)超過35℃，水(shui)壓在0.3一(yi)0.5MPA之間流(liu)量應不(bu)小于規(gui)定流量(liang)的😌90％。環境(jing)溫🧛🏾‍♀️度不(bu)應高于(yu)🚶🏾‍♀️‍➡️40℃。如果達(da)不到上(shang)述要求(qiu)，可通過(guo)安裝冷(leng)卻塔、改(gai)善室内(nei)通風、加(jia)大機房(fang)空間等(deng)辦法解(jie)決。還😗可(ke)檢查冷(leng)卻😈風扇(shan)工作是(shi)否正常(chang)。如有故(gu)障應進(jin)行檢修(xiu)或更換(huan)。

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(leng)機組主(zhu)要檢查(cha)進出油(you)溫相差(cha)是否在(zai)10度左右(you)🛌🏻，如果小(xiao)于🧑🏽‍🎄這個(ge)值則應(ying)檢查散(san)熱器表(biao)面翅片(pian)是否髒(zang)堵，如果(guo)髒堵可(ke)用潔淨(jing)空氣将(jiang)散熱器(qi)表面粉(fen)塵，并檢(jian)查散熱(re)器翅片(pian)是否腐(fu)蝕，腐蝕(shi)🧑🏾‍🎄厲害的(de)話則有(you)必要考(kao)慮更換(huan)散熱器(qi)總成，内(nei)部管道(dao)是否有(you)髒👋堵現(xian)象，若有(you)此現象(xiang)則可用(yong)循環泵(beng)循環帶(dai)一定酸(suan)性藥水(shui)清洗，一(yi)定要注(zhu)意藥水(shui)👾濃度，以(yi)及循環(huan)時間，避(bi)免散熱(re)器因藥(yao)^水腐蝕(shi)造成散(san)熱器穿(chuan)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.
