一、環(Huan)境溫度(Du)過高對螺杆空壓機造成高(Gao)溫這個主要[Yao]從二個方面[Mian]來影響空壓機(Ji)。A:溫(Wen)度越高，空氣越是[Shi]稀薄（就好(Hao)象空壓機在高原[Yuan]地區效(Xiao)率低(Di)一樣），造成空壓機工作效(Xiao)率下降，使空壓機更多時(Shi)間處于加載狀[Zhuang]态，帶更多負載，造(Zao)成空壓機産生的[De]熱量(Liang)更多，空壓機(Ji)肯[Ken]定溫(Wen)度就更高[Gao]。B:一(Yi)般空壓機設(She)計(Ji)的時候就[Jiu]有一個[Ge]設計(Ji)運行環境溫[Wen]度（30-40度），在設計(Ji)運行環境溫度下運行(Hang)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[Guo]空壓機環(Huan)境(Jing)溫度高于設[She]計運行環境溫度，就會提高空壓機的(De)溫度從而使空壓機到底(Di)甚至超過空(Kong)壓機的停機溫度，從而造成空壓機高溫(Wen)。

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、空壓機系統缺油。可檢查油氣桶[Tong]油位，在停機洩壓後，潤滑油處于靜(Jing)态[Tai]時，油位應比高油位标志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MIX）。如發[Fa]現油[You]量不足或(Huo)觀察不到[Dao]油位時[Shi]，應立(Li)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[Fa]（斷油閥）工作不正常。油(You)停止閥一般為[Wei]兩位兩通常閉電磁閥，起動時開啟，停機時關閉，（atlascopco機器為機械[Xie]式開啟閥）以避免停機時[Shi]油氣桶内的油繼續[Xu]噴入機頭，并從[Cong]進氣口噴出。若(Ruo)該元件加載時(Shi)不開啟，主機會[Hui]因缺油迅速升溫，嚴重者會造(Zao)成螺杆總成燒(Shao)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[Lü]器問[Wen]題A:機油過濾器堵[Du]塞(Sai)旁通閥又不開啟會造成(Cheng)空壓機油不(Bu)能到達機頭[Tou]，主機會因缺油迅速升溫。B:機油過濾器[Qi]堵塞流(Liu)量變小(Xiao)，有一種(Zhong)情況就是空壓機因為熱量(Liang)帶走的不是[Shi]很完[Wan]全空壓(Ya)機溫度慢慢(Man)升高形成高溫，另外一種情況是空壓機卸載後空(Kong)壓機高溫，因[Yin]為空壓[Ya]機在加載[Zai]是内[Nei]部油壓高，空壓機油可以通過，而空壓機卸載後空壓機油壓力低空壓機油(You)通過空壓機(Ji)機油過濾器困難，流量太小(Xiao)從而造成空壓機高(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(Wu)、熱控閥（溫控閥[Fa]）工作失靈。熱控閥安裝于油冷卻器前方，其作用[Yong]是維持機頭[Tou]排氣溫度于(Yu)壓力露點以(Yi)上。其[Qi]工作原理[Li]是剛開機時由于油(You)溫較低，熱控閥支路(Lu)開啟[Qi]，主回路關閉，潤[Run]滑油不經冷卻器直[Zhi]接噴入機頭；待溫[Wen]度升至(Zhi)40℃以上，熱[Re]控閥逐[Zhu]漸關閉，油同時從冷卻器和支路流過；升(Sheng)高到[Dao]80℃以上，該閥完全關閉，潤滑油則全(Quan)部經冷卻器再進入機[Ji]頭，以zui大程度對潤滑油進行冷卻。如果熱[Re]控閥出現(Xian)故障，則潤滑油可能不經冷[Leng]卻(Que)器直接進入機頭，從[Cong]而[Er]油溫無法下降，造成超(Chao)溫。其失靈的(De)主(Zhu)要原因，一是閥[Fa]芯上的大[Da]小兩個熱敏彈簧疲勞後彈性系數改變，不能随溫[Wen]度變化而正常動作；二是(Shi)閥體磨損，閥芯卡死[Si]或動作不到位而無法正常關(Guan)閉。可根據情況修複或[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(Liu):檢查油量(Liang)調節器是否正常（對于複盛等機組[Zu]有油量調節閥），必要時可适當加大[Da]噴(Pen)油量。噴(Pen)油量在設備出廠時已調好，一(Yi)般情況下不宜(Yi)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、機油超過使用(Yong)時間機(Ji)油變質。流動性[Xing]變[Bian]差，熱交換熱[Re]性能(Neng)下降。造成空壓機機(Ji)頭的熱量不能完(Wan)全帶走造成空壓[Ya]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[Cha]油冷卻器(Qi)工作是否正常。對水冷式機[Ji]型，可檢[Jian]查其[Qi]進出(Chu)口水(Shui)管的溫差，正常[Chang]情況下應為(Wei)5一[Yi]8℃，低于5℃可能有結垢或堵(Du)塞現象，将會影響冷卻器(Qi)的換熱效率，并造成散熱不良，此[Ci]時可[Ke]将(Jiang)換熱器拆(Chai)下後進行清洗。

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)冷卻水人口溫度是[Shi]否過高，水壓及流量是否正常，對于風冷式機型則檢(Jian)查環境(Jing)溫度是否過高。冷卻水的[De]入口溫度(Du)一般[Ban]不應超過35℃，水壓在0.3一0.5MPA之[Zhi]間流量應不小于(Yu)規定流量的90％。環境溫度不應高于40℃。如果達不到上述[Shu]要求，可通過安裝冷卻塔、改善室内通風、加大[Da]機房空間等辦法解決。還可檢查冷(Leng)卻風扇工[Gong]作(Zuo)是否正常。如[Ru]有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[Yao]檢查進出油溫相差是否在10度[Du]左右，如果小于(Yu)這個值則應檢[Jian]查散熱[Re]器表面翅片[Pian]是否髒堵(Du)，如果髒(Zang)堵可用(Yong)潔淨空氣[Qi]将散[San]熱器表面(Mian)粉塵，并檢查散熱器(Qi)翅片(Pian)是否腐蝕(Shi)，腐[Fu]蝕厲害的話(Hua)則有(You)必要考慮[Lü]更換散熱器總成，内部管[Guan]道是否有髒堵現象[Xiang]，若(Ruo)有此現象則(Ze)可用循環泵循(Xun)環帶一定[Ding]酸性藥水清洗，一定(Ding)要注意藥水濃度(Du)，以及循環時間，避免散[San]熱(Re)器因藥水腐蝕造[Zao]成散熱器穿腔。

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.
