一、環(huan)境溫度過(guò)高對螺杆(gǎn)空壓機造(zào)成高溫這(zhè)個主要從(cóng)二個方面(miàn)來影響空(kōng)壓機。A:溫度(dù)越高，空氣(qi)越是稀薄(báo)（就好象空(kong)壓機在高(gao)原地區效(xiao)率低一樣(yang)），造成☎️空壓(ya)機工作效(xiào)率下降🈲，使(shi)空壓機更(geng)多時間處(chù)于加載狀(zhuang)态，帶更多(duo)負載，造成(cheng)空壓機産(chan)生的熱量(liàng)更多，空壓(yā)機肯定溫(wēn)度就更高(gao)。B:一般空壓(yā)機設計的(de)時候就有(yǒu)一個設🏃計(jì)運行環境(jìng)溫度🔅（30-40度），在(zai)設計運行(hang)🈲環境溫度(du)下運行空(kōng)壓🏃🏻機一般(bān)zui高溫度就(jiù)快接近空(kōng)壓機保護(hù)溫度，如果(guo)空壓機環(huan)境溫度高(gāo)于設♊計運(yùn)行環境溫(wen)度，就會提(tí)高空壓機(jī)的溫度從(cóng)而使空壓(yā)🔞機到✍️底甚(shèn)至超過空(kong)壓機的停(ting)機溫度，從(cóng)而造成空(kong)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(ji)系統缺油(yóu)。可檢查油(you)氣桶油位(wei)，在停機洩(xie)✉️壓後，潤滑(hua)油處于靜(jing)态時，油位(wei)應比高油(you)位标志H（或(huo)MAX）略高。在設(shè)備運行過(guò)程中，油位(wèi)不能低于(yú)低油位标(biāo)志L（或MIX）。如發(fa)現油量不(bú)足或觀察(cha)✂️不到油位(wèi)時，應立即(ji)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(zhǐ)閥（斷油閥(fá)）工作不正(zhèng)常。油停止(zhi)閥一般為(wei)☂️兩位兩⚽通(tong)常閉電磁(cí)閥，起動時(shi)開啟，停機(ji)時關閉，（atlascopco機(ji)器為機械(xie)☁️式開啟閥(fa)）以避免停(tíng)機時油氣(qì)桶内的油(yóu)繼續噴入(rù)機頭，并從(cong)進氣口噴(pen)出。若該元(yuan)件加載時(shi)不開啟，主(zhu)機會因缺(que)油迅速升(shēng)🐅溫，嚴重者(zhě)會造成螺(luó)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、機油(yóu)過濾器問(wèn)題A:機油過(guò)濾器堵塞(sai)旁通閥又(yòu)不開☀️啟會(hui)造成空壓(yā)機油不能(néng)到達機頭(tóu)，主機會因(yīn)缺油迅速(su)升溫。B:機油(yóu)過🔴濾器👣堵(du)塞流量變(bian)小，有一種(zhong)情況就是(shi)空壓機因(yin)為熱量帶(dai)走的不是(shì)♻️很完全空(kong)壓機溫度(dù)慢♻️慢升高(gāo)形‼️成高溫(wēn)，另外一種(zhǒng)情況是空(kong)壓🙇♀️機卸載(zǎi)後空壓機(ji)高溫，因為(wei)空壓機在(zài)❓加載是内(nei)部油壓高(gao)，空壓機油(yóu)可以通過(guo)，而空壓機(jī)卸載後空(kōng)壓機油壓(ya)力低空壓(ya)機油通過(guo)空壓機機(jī)油過濾器(qì)困難，流量(liang)太小從而(er)造成空壓(yā)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(wēn)控閥）工作(zuo)失靈。熱控(kòng)閥安裝于(yu)油冷卻器(qi)前方💁，其❌作(zuo)用是維持(chí)機頭排氣(qi)溫度于壓(ya)力露點以(yǐ)上。其工作(zuò)原理是剛(gāng)開機時由(you)于油溫較(jiào)低，熱控⁉️閥(fá)支路開啟(qǐ)，主回路關(guān)閉，潤滑♻️油(you)不經冷卻(que)器直接噴(pen)入機頭🤟；待(dai)溫度升㊙️至(zhì)40℃以上，熱控(kong)閥逐漸關(guān)閉，油同時(shí)從冷卻器(qì)🔞和支路流(liú)過；升高到(dao)80℃以上，該閥(fá)完全關閉(bi)，潤滑油則(ze)全💁部經冷(leng)卻器再進(jin)入機頭，以(yi)zui大程度🧑🏾🤝🧑🏼對(dui)潤滑油🥰進(jìn)行冷🈲卻。如(rú)果熱控閥(fa)出現故障(zhàng)，則潤滑油(you)可能不經(jing)冷卻器直(zhi)接進入機(ji)頭，從而🌈油(yóu)溫無法下(xia)降，造成超(chāo)溫。其失靈(ling)的主要原(yuan)因，一是閥(fa)芯上的👣大(da)小兩個熱(re)敏彈簧疲(pi)勞後彈性(xìng)系數改變(bian)，不能随溫(wēn)度變化而(ér)✌️正常動作(zuò)；二是閥體(ti)磨損，閥芯(xin)卡死或動(dòng)作不到位(wei)而無法正(zheng)常✨關閉。可(kě)根據情況(kuàng)修複或更(gèng)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(chá)油量調節(jie)器是否正(zhèng)常（對于複(fu)盛等機組(zu)有🔞油🐇量調(diao)節閥），必要(yào)時可适當(dang)加大噴油(yóu)量。噴油量(liang)在設備出(chu)廠時已調(diào)好，一般情(qing)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(jī)油超過使(shi)用時間機(jī)油變質。流(liú)動性變差(chà)，熱交換熱(re)性能下降(jiàng)。造成空壓(yā)機機頭的(de)熱量不能(néng)完全♌帶走(zou)造成🙇♀️空壓(yā)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(bā)、檢查油冷(lěng)卻器工作(zuò)是否正常(chang)。對水冷式(shì)機型，可檢(jian)查其進出(chū)口水管的(de)溫差，正常(chang)情況下應(ying)為5一8℃，低于(yú)5℃可能有結(jié)垢🐪或堵塞(sai)現象，将會(hui)影響冷卻(que)器的換熱(re)效率，并造(zào)成🏒散熱不(bu)良，此時可(kě)将換熱器(qì)拆下後進(jìn)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(jiu)、檢查冷卻(que)水人口溫(wēn)度是否過(guo)高，水壓及(ji)流量是否(fou)正✔️常，對🐕于(yú)風冷式機(ji)型則檢查(chá)環境溫度(dù)是否過高(gao)。冷卻水的(de)入口溫度(du)一般不應(yīng)超過35℃，水壓(ya)在0.3一0.5MPA之間(jiān)流量應不(bú)小于規定(ding)流量的90％。環(huán)境溫度不(bú)應高于40℃。如(ru)果達不到(dào)上述要求(qiú)，可通過安(an)裝冷卻塔(ta)、改善室🏃♀️内(nèi)通風、加大(dà)機房空間(jian)等辦法解(jie)決。還☂️可檢(jiǎn)查冷卻風(fēng)扇工作是(shi)📐否正常。如(ru)有故障應(ying)進行檢修(xiū)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(shi)、風冷機組(zǔ)主要檢查(chá)進出油溫(wen)相差是否(fǒu)在10度左右(yòu)，如果小于(yu)這個值則(zé)應檢查散(sàn)熱器表面(miàn)翅片是否(fǒu)髒📞堵，如🌂果(guo)髒堵可用(yòng)潔淨空氣(qi)将散熱器(qi)表面粉塵(chén)，并檢查散(san)熱👉器翅片(pian)是否腐蝕(shi)，腐蝕厲害(hai)的話則有(yǒu)必要考慮(lǜ)更換散熱(rè)器總成，内(nèi)部管道是(shi)否有髒堵(dǔ)現象，若有(you)此現象則(ze)可用循環(huán)泵循環帶(dài)一定酸性(xìng)藥水清洗(xi)，一定要注(zhù)意藥水濃(nong)度，以及循(xun)環時間🐇，避(bi)免散熱❗器(qi)因藥🛀🏻水腐(fǔ)蝕造成散(sàn)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.
