一、環境溫度過[Guo]高對螺杆空(Kong)壓機造成高(Gao)溫這個主要從二個方面[Mian]來影響空壓(Ya)機(Ji)。A:溫度(Du)越高，空氣越是[Shi]稀薄（就好象空壓機[Ji]在高原地區效率低[Di]一樣），造成空壓機工作效率下降，使空壓機更多時間處于加載狀态，帶更多負載，造成空壓機産生的熱[Re]量更多，空壓機肯(Ken)定溫(Wen)度就更高。B:一(Yi)般(Ban)空壓機設計的(De)時候就(Jiu)有一個設計運行環境溫[Wen]度（30-40度），在設計[Ji]運行環境溫度下運行空壓機一般zui高[Gao]溫[Wen]度[Du]就快接近空壓機[Ji]保護溫度[Du]，如果空壓(Ya)機環境溫度高[Gao]于設[She]計運行環境(Jing)溫[Wen]度，就會提高空壓機的(De)溫(Wen)度從而使空壓機到底(Di)甚至超過空壓機[Ji]的[De]停機溫度，從而造(Zao)成空壓機高[Gao]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(Kong)壓機系統缺油(You)。可檢查油氣桶油[You]位，在停機[Ji]洩壓後，潤滑油處(Chu)于靜态(Tai)時，油位應比[Bi]高油[You]位标(Biao)志H（或MAX）略高。在設[She]備運行過程中[Zhong]，油位不能低于(Yu)低油位标志L（或MIX）。如發[Fa]現油量不足(Zu)或觀(Guan)察不到(Dao)油位時，應立即停車加油[You]

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（斷[Duan]油閥）工作不正常。油[You]停止閥一般為兩位兩通常閉[Bi]電磁閥，起動時開啟，停機時關閉，（atlascopco機器為機械式[Shi]開(Kai)啟閥）以避(Bi)免停機時油氣桶内的油繼續(Xu)噴入機頭，并從進氣[Qi]口噴出。若該(Gai)元件加載時(Shi)不開啟，主機會因缺油迅速升溫，嚴重者會造成螺杆總成燒(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[Si]、機油過濾[Lü]器問題[Ti]A:機油過濾器堵塞旁通閥又不開啟會造成空壓機油不能到達機頭[Tou]，主機(Ji)會因缺油(You)迅速升溫[Wen]。B:機油過濾器[Qi]堵塞流量變小，有一種情(Qing)況就是空壓機因為熱量帶(Dai)走的不是很完(Wan)全空壓機溫度慢慢[Man]升高形成高溫，另外一種情況是空[Kong]壓[Ya]機[Ji]卸載後空壓機高溫(Wen)，因為空壓機在加載是内部[Bu]油壓高，空壓(Ya)機油可以通過(Guo)，而空壓[Ya]機卸載後空壓[Ya]機油壓力低空壓機[Ji]油通過空壓機機[Ji]油過濾器困[Kun]難，流量太小從而造成空壓機高溫。

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（溫控閥）工作失靈(Ling)。熱控閥安裝[Zhuang]于油冷卻器前方(Fang)，其作用是維持(Chi)機頭排氣溫度于[Yu]壓力露點以(Yi)上。其工作原理是剛開機(Ji)時由[You]于油[You]溫較低(Di)，熱控閥支路開啟[Qi]，主回路關閉，潤[Run]滑油不經冷(Leng)卻器直[Zhi]接噴入機(Ji)頭；待溫度升至40℃以上，熱控閥逐[Zhu]漸(Jian)關閉，油同時從冷卻器和支路流過；升(Sheng)高到80℃以上，該閥完全關閉，潤滑油則[Ze]全部(Bu)經冷卻器再進入機[Ji]頭，以zui大程度對潤滑[Hua]油進行冷卻。如果熱控閥出現故障，則潤[Run]滑油(You)可能不經冷卻器直接進入機頭，從(Cong)而油溫無法下降，造成超[Chao]溫。其失靈的主[Zhu]要原因，一是[Shi]閥芯上的大小兩個熱敏彈簧疲勞後彈性系數改[Gai]變，不能(Neng)随溫度變化而正常動作；二是(Shi)閥體磨損，閥芯卡死或(Huo)動(Dong)作不到位而[Er]無法正常關閉。可根(Gen)據情況修複或更換。

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[Liu]:檢查油量調(Diao)節器是否正常（對[Dui]于[Yu]複盛等機組有油量調節閥(Fa)），必要時可(Ke)适當加大噴油量。噴油量在設備出廠(Chang)時已調好，一[Yi]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、機油超過(Guo)使用時間機油變質。流動性[Xing]變差，熱(Re)交換熱(Re)性能下降。造成空壓機機頭的熱量不能完全帶走造成空壓(Ya)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、檢查油冷卻器工作是否正(Zheng)常。對水(Shui)冷式機型，可檢查其[Qi]進出口水管的溫差，正常(Chang)情況下應為(Wei)5一[Yi]8℃，低(Di)于5℃可能有結垢或堵(Du)塞現象，将會影響[Xiang]冷卻[Que]器的換熱[Re]效率[Lü]，并造成散熱不良，此時可将換(Huan)熱器拆下(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、檢查冷卻[Que]水人口溫[Wen]度是否過高，水壓及流量[Liang]是否[Fou]正常，對于風冷[Leng]式機[Ji]型則檢查(Cha)環(Huan)境溫度是否(Fou)過(Guo)高。冷卻水的[De]入口(Kou)溫度一般不應超(Chao)過35℃，水壓在0.3一[Yi]0.5MPA之間(Jian)流量應不小于規定流量的90％。環境[Jing]溫度不應高[Gao]于40℃。如(Ru)果達不到上述要求，可通過安裝冷卻塔、改善(Shan)室内通風[Feng]、加大機房(Fang)空間等辦法解決。還可檢[Jian]查冷卻風扇工作是否正常。如有故障應進(Jin)行(Hang)檢修或更(Geng)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、風冷機組主要檢查進出油溫相差是否在10度[Du]左右，如果(Guo)小于(Yu)這個值則應檢(Jian)查散熱器表面翅片(Pian)是否髒堵，如果髒堵可用(Yong)潔淨空氣将[Jiang]散[San]熱器表面(Mian)粉塵[Chen]，并檢查散熱器[Qi]翅片是否腐蝕，腐蝕厲害的話(Hua)則有必要考慮(Lü)更換[Huan]散熱器總成，内部管道是否有髒堵現象[Xiang]，若有此現象則[Ze]可用循環泵[Beng]循環帶一定酸性藥水清(Qing)洗，一定要注[Zhu]意藥水濃度，以及循環時[Shi]間，避免散熱[Re]器(Qi)因藥水腐蝕造成[Cheng]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.
