一、環境溫度過高對[Dui]螺杆空壓機造成高溫這個主[Zhu]要從二個方面(Mian)來影響空壓機。A:溫度越高，空氣(Qi)越是(Shi)稀(Xi)薄（就好象空壓機在高原地區效率低[Di]一樣），造成空壓[Ya]機工作效率下降，使空壓(Ya)機更多[Duo]時間處于加載狀态，帶更多負載，造(Zao)成空壓機産生的(De)熱量更多，空[Kong]壓機(Ji)肯(Ken)定溫(Wen)度就更高。B:一般空壓機設(She)計[Ji]的時候[Hou]就有(You)一個設計運行環境溫(Wen)度（30-40度），在[Zai]設計(Ji)運行環境溫度下運行空壓機一般zui高(Gao)溫[Wen]度就快接近空(Kong)壓機保護溫度，如果空壓機環境溫度高于設計運行環境溫度，就(Jiu)會提高空壓機的溫度從(Cong)而使空壓機到(Dao)底[Di]甚至超過空(Kong)壓機(Ji)的停機(Ji)溫度，從而造[Zao]成空壓機高溫。

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、空(Kong)壓機[Ji]系統缺油。可檢[Jian]查油氣桶[Tong]油位，在停機洩壓後，潤滑油處[Chu]于靜[Jing]态(Tai)時，油位應比[Bi]高油位标志H（或MAX）略高。在設備運行過程[Cheng]中，油位不能低于低油位标志L（或[Huo]MIX）。如發現油量不足或觀察不到(Dao)油位時，應立即停車加油

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、油停止閥(Fa)（斷油[You]閥[Fa]）工作(Zuo)不正常。油[You]停止閥一般為兩位兩通常閉電磁閥，起動時開啟，停機時關[Guan]閉，（atlascopco機器為機械式開[Kai]啟閥）以避免停機時油氣(Qi)桶内的油(You)繼續噴入機(Ji)頭，并從進氣[Qi]口噴出。若該元件[Jian]加(Jia)載時[Shi]不開啟，主(Zhu)機會因缺油迅速(Su)升溫，嚴(Yan)重(Zhong)者會造(Zao)成螺杆總成燒毀(Hui)。

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、機油過濾器問題A:機油[You]過濾器[Qi]堵[Du]塞旁通閥又不(Bu)開[Kai]啟會造成空壓機(Ji)油(You)不能到達機頭(Tou)，主機會因缺[Que]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)況就是空壓機因為熱(Re)量(Liang)帶走的不是[Shi]很完(Wan)全空壓機溫度慢慢升高形成高溫[Wen]，另外一種(Zhong)情況是空壓機[Ji]卸載後空(Kong)壓機高溫，因為空[Kong]壓機在加載[Zai]是内[Nei]部油壓高，空壓機油可以通(Tong)過(Guo)，而空[Kong]壓機卸載[Zai]後空壓[Ya]機油壓[Ya]力低空壓機油通過空壓機(Ji)機(Ji)油過(Guo)濾器困(Kun)難(Nan)，流量太小從而造(Zao)成空壓機高溫。

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[Wen]控閥）工作失靈[Ling]。熱控閥安裝于(Yu)油冷卻器(Qi)前[Qian]方，其作用是維持機頭排氣溫度于(Yu)壓力露點以(Yi)上。其工作原理[Li]是剛開機[Ji]時由于油[You]溫較低，熱控閥支路[Lu]開啟，主回路關閉，潤(Run)滑油不經冷卻器直接噴(Pen)入機頭；待[Dai]溫度升至40℃以上，熱控閥逐漸[Jian]關閉，油同時(Shi)從冷卻器和支路流過；升高到80℃以上，該閥完全關(Guan)閉，潤滑油則(Ze)全部經冷卻器(Qi)再進入(Ru)機頭[Tou]，以zui大程度對潤滑[Hua]油進行冷卻。如果熱[Re]控閥出現故障，則潤(Run)滑油可能不經冷卻(Que)器直接進(Jin)入機[Ji]頭，從而油溫無法下(Xia)降，造[Zao]成超(Chao)溫。其失靈的主[Zhu]要原因，一是閥[Fa]芯上(Shang)的大(Da)小兩個熱敏彈簧疲勞後(Hou)彈性系數(Shu)改變，不能随溫度變化而[Er]正常動作；二是閥體磨損，閥[Fa]芯卡死或動作不到位而無法正常關[Guan]閉。可[Ke]根據[Ju]情況修複或(Huo)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:檢查油量調節器是[Shi]否正常（對于(Yu)複盛等機組[Zu]有油量調節閥），必要時可适當加大[Da]噴油量。噴油量在設備出廠時已調好，一般情況下不宜改變(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、機油超(Chao)過使用(Yong)時間機[Ji]油變(Bian)質。流動性[Xing]變差[Cha]，熱交換熱性能下降。造成空壓機機[Ji]頭的熱量不能完全帶走[Zou]造成空壓機高溫。

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、檢查油[You]冷卻器工作是否正常。對水[Shui]冷式機型，可檢查其進出[Chu]口水管的溫差，正(Zheng)常[Chang]情況下應為5一(Yi)8℃，低于5℃可能有結垢[Gou]或堵塞現象，将會影響冷卻器的換熱效率(Lü)，并造成散熱[Re]不良，此[Ci]時可将[Jiang]換熱器拆[Chai]下[Xia]後進行清洗。

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(Cha)冷(Leng)卻水人口溫(Wen)度是否過高，水壓及流[Liu]量是否正常，對[Dui]于風冷式機型則檢查(Cha)環[Huan]境溫度是否(Fou)過高。冷卻水的入[Ru]口溫度一般不應超過35℃，水壓在0.3一0.5MPA之[Zhi]間流量應[Ying]不小于規定流量的90％。環境[Jing]溫(Wen)度不應高[Gao]于40℃。如(Ru)果達[Da]不到上述要(Yao)求，可通過安裝冷(Leng)卻塔、改善室内通風、加[Jia]大機房空間等辦[Ban]法解決。還可檢查冷(Leng)卻風扇工(Gong)作[Zuo]是否正常。如有[You]故障應進行檢修或更換。

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、風冷機[Ji]組主要檢查[Cha]進出油溫相差是否在10度(Du)左右，如果小于這個值則應檢[Jian]查散熱器表面翅片[Pian]是否髒堵(Du)，如果髒堵可用[Yong]潔淨空氣将散熱器表面粉[Fen]塵，并檢查散熱器翅片是否腐蝕，腐蝕厲害的話[Hua]則有必要考慮更換散熱器總成，内部管道是[Shi]否有髒堵現象(Xiang)，若有此現象則[Ze]可用循環泵[Beng]循環帶一定酸性藥水清洗，一定要注意藥水濃[Nong]度，以及循[Xun]環時(Shi)間，避免散熱器因藥水腐蝕造成散熱器穿腔(Qiang)。

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.
