一、環(huán)境溫(wēn)度過高對(duì)螺杆空(kōng)壓機造成高(gāo)溫這(zhè)個主要從(cóng)二個方面(miàn)來影(yǐng)響空(kōng)壓機(jī)。a:溫度(dù)越高，空氣(qì)越是稀(xī)薄（就好(hǎo)象空(kōng)壓(yā)機在高(gāo)原地(dì)區效率低(dī)一樣），造(zào)成(chéng)空(kōng)壓機工作效率下(xià)降，使(shǐ)空壓機更多時間(jiān)處(chù)于加(jiā)載狀(zhuàng)态(tài)，帶(dài)更多(duō)負載(zǎi)，造成(chéng)空壓機産生的熱量更多，空(kōng)壓(yā)機肯(kěn)定溫度就(jiù)更高。b:一般空壓機設(shè)計的時候(hòu)就有(yǒu)一個(gè)設計(jì)運行(háng)環境溫(wēn)度（30-40度），在(zài)設計運行環境溫度下運行空壓機一般zui高溫(wēn)度就快接近空壓機保護溫度(dù)，如果空壓機環(huán)境溫度高(gāo)于設(shè)計運行(háng)環(huán)境(jìng)溫度，就(jiù)會提高空(kōng)壓機(jī)的(de)溫度從(cóng)而使(shǐ)空壓機到(dào)底甚至超(chāo)過空壓機(jī)的(de)停機溫(wēn)度，從(cóng)而(ér)造(zào)成空(kōng)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、空壓機系統(tǒng)缺油(yóu)。可檢(jiǎn)查油(yóu)氣桶(tǒng)油位(wèi)，在停機(jī)洩(xiè)壓後，潤滑(huá)油處(chù)于靜态時，油位(wèi)應比高油位标(biāo)志h（或max）略高(gāo)。在設(shè)備運行(háng)過程(chéng)中(zhōng)，油位不(bú)能(néng)低于低油位标志l（或(huò)mix）。如發(fā)現(xiàn)油(yóu)量不足或(huò)觀察不到(dào)油位時，應(yīng)立即(jí)停車加(jiā)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（斷油閥(fá)）工作(zuò)不正(zhèng)常。油(yóu)停止閥一般為兩位兩(liǎng)通常閉(bì)電磁閥，起(qǐ)動時(shí)開啟，停機(jī)時關(guān)閉，（atlascopco機器為(wéi)機械式開啟(qǐ)閥(fá)）以避(bì)免停機時油(yóu)氣(qì)桶内的油繼續(xù)噴入機(jī)頭，并從(cóng)進氣(qì)口噴出。若(ruò)該元件加載時不開(kāi)啟，主機會因缺油迅速升(shēng)溫，嚴重者會造(zào)成螺杆(gǎn)總(zǒng)成燒(shāo)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、機油過濾(lǜ)器問(wèn)題a:機油過濾器堵塞旁通閥又不開(kāi)啟會(huì)造成(chéng)空壓機油(yóu)不(bú)能到達(dá)機頭，主機會因缺油(yóu)迅速升溫(wēn)。b:機油(yóu)過濾(lǜ)器(qì)堵塞流量變小，有(yǒu)一種(zhǒng)情況就是空壓(yā)機因(yīn)為熱量帶走的不是(shì)很完(wán)全空壓(yā)機溫度(dù)慢慢升高形成(chéng)高溫，另外一種(zhǒng)情況是空壓機(jī)卸載後(hòu)空壓機高溫，因為空壓(yā)機在加載是内部油壓(yā)高，空壓(yā)機油(yóu)可以(yǐ)通過，而空壓機卸載(zǎi)後空壓(yā)機(jī)油壓力低空壓機油(yóu)通過(guò)空(kōng)壓(yā)機機(jī)油過濾器困難(nán)，流量太小(xiǎo)從而(ér)造成空壓機高(gāo)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、熱控(kòng)閥（溫(wēn)控閥）工作(zuò)失靈(líng)。熱控閥(fá)安裝于油冷卻器(qì)前方(fāng)，其作(zuò)用(yòng)是維持機頭(tóu)排氣溫度(dù)于(yú)壓力露(lù)點以(yǐ)上。其工作原理(lǐ)是剛(gāng)開機(jī)時由(yóu)于油(yóu)溫(wēn)較低，熱(rè)控閥(fá)支路(lù)開啟，主回路關閉，潤(rùn)滑油不經冷卻(què)器直接噴入機(jī)頭；待(dài)溫(wēn)度(dù)升至40℃以上(shàng)，熱控閥逐(zhú)漸關閉，油同時(shí)從冷卻(què)器和支(zhī)路流(liú)過；升高到80℃以上(shàng)，該閥完全(quán)關閉(bì)，潤滑(huá)油則全部經冷卻器(qì)再進入(rù)機(jī)頭，以zui大程度對潤滑(huá)油進行(háng)冷卻。如(rú)果熱(rè)控閥出現(xiàn)故障，則潤(rùn)滑油(yóu)可能(néng)不(bú)經冷卻(què)器直接進(jìn)入機(jī)頭，從而油(yóu)溫無(wú)法下降，造成超溫。其失(shī)靈的主(zhǔ)要原因，一(yī)是(shì)閥芯上的大小兩個熱敏彈簧疲勞後(hòu)彈性系數改變，不能(néng)随溫度變化(huà)而(ér)正常(cháng)動作；二是閥體(tǐ)磨損，閥芯卡死(sǐ)或動(dòng)作不(bú)到位而無法正常關(guān)閉。可根據(jù)情(qíng)況(kuàng)修複(fú)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(liù):檢查油(yóu)量調節器是(shì)否正常（對(duì)于複盛(shèng)等機組(zǔ)有油量調節閥(fá)），必要(yào)時可适當(dāng)加大噴油(yóu)量。噴(pēn)油量在設備出廠時已調好，一(yī)般情(qíng)況下不宜改變。

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(jī)油超(chāo)過使用時間機(jī)油變質。流(liú)動性(xìng)變差(chà)，熱交(jiāo)換熱(rè)性能下降。造(zào)成(chéng)空壓機機頭的(de)熱量(liàng)不能完全(quán)帶走造成空壓機(jī)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(chá)油冷卻(què)器工(gōng)作(zuò)是否(fǒu)正(zhèng)常。對水冷式機(jī)型，可檢查其(qí)進出口水(shuǐ)管的溫差(chà)，正常(cháng)情況下應為5一(yī)8℃，低于5℃可(kě)能有結(jié)垢或(huò)堵(dǔ)塞現象(xiàng)，将會影響冷卻器的換熱效率(lǜ)，并造成散熱不(bú)良，此時可(kě)将換(huàn)熱器拆下後進(jìn)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(chá)冷卻水(shuǐ)人(rén)口溫度是否過高，水(shuǐ)壓及流量是否正常，對于(yú)風冷(lěng)式機型則檢查(chá)環境(jìng)溫度是否(fǒu)過高。冷卻水的(de)入口(kǒu)溫(wēn)度一般(bān)不應超過35℃，水壓在0.3一(yī)0.5mpa之間流量(liàng)應不(bú)小于(yú)規定(dìng)流量的90％。環境溫(wēn)度不(bú)應高于40℃。如(rú)果達不到上述(shù)要求，可通過安裝(zhuāng)冷(lěng)卻塔、改善(shàn)室内通(tōng)風、加大機房空間等辦(bàn)法解決(jué)。還可檢(jiǎn)查冷(lěng)卻(què)風扇工(gōng)作是否正(zhèng)常。如(rú)有故(gù)障應(yīng)進行(háng)檢修(xiū)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(shí)、風冷機(jī)組主要檢查(chá)進出油溫(wēn)相差是(shì)否在10度(dù)左右(yòu)，如果小于這個值則應檢(jiǎn)查散熱(rè)器表面翅片是否髒堵(dǔ)，如果(guǒ)髒堵可用(yòng)潔淨空氣将散熱器表面粉塵，并檢查(chá)散(sàn)熱器翅片是否腐蝕(shí)，腐蝕(shí)厲害(hài)的話(huà)則有必要考(kǎo)慮(lǜ)更換散熱(rè)器總(zǒng)成，内部管道是否有(yǒu)髒堵(dǔ)現象，若有(yǒu)此(cǐ)現象則(zé)可用(yòng)循(xún)環泵循(xún)環帶一定酸性(xìng)藥水(shuǐ)清(qīng)洗，一定要注意藥水濃(nóng)度，以(yǐ)及循環時(shí)間，避免散熱器(qì)因藥(yào)水腐蝕造(zào)成散熱器穿腔(qiāng)。

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.
