自上料攪拌車為了防止漏油現(xiàn)象的發(fā)生，我們該采取一些預(yù)防措施：

In order to prevent oil leakage, we should take some preventive measures

自上料攪拌車漏油一般有幾方面的原因：

There are several reasons for the oil leakage of self feeding mixer truck

1. 車輛配件的質(zhì)量、材料或工藝有問題或結(jié)構(gòu)設(shè)計(jì)不合理。

1. There are problems in the quality, material or process of vehicle accessories or unreasonable structural design.

2. 裝配不當(dāng)，配合表面不清潔，襯墊破損、位移或未按操作規(guī)程進(jìn)行安裝。

2. Improper assembly, unclean mating surface, damaged gasket, displacement or installation not in accordance with operating procedures.

3. 配件之間的螺母擰力不均勻，滑絲斷扣或松曠脫落等導(dǎo)致工作失效。

3. Uneven tightening force of nuts between accessories, broken or loose sliding wire lead to work failure.

4. 使用年限長的專用車的密封件磨損嚴(yán)重，老態(tài)變質(zhì)或變形失效。

4. The seals of special vehicles with long service life are seriously worn, deteriorated or deformed.

5. 潤滑油的添加量過多，油面過高或加錯(cuò)油品。

5. Too much lubricating oil, too high oil level or wrong oil.

6. 零部件的接合表面扭曲變形、殼體破損，使?jié)櫥蜐B出。

6. The joint surface of parts is distorted and the shell is damaged, which makes the lubricating oil seep out.

7. 通氣塞，單向閥堵塞后，由于箱殼內(nèi)外氣壓差的作用，會引起密封薄弱處漏油。

7. After the vent plug and one-way valve are blocked, due to the effect of the air pressure difference inside and outside the box shell, it will cause oil leakage at the weak part of the seal.
             

預(yù)防自上料攪拌車漏油的措施：

Measures to prevent oil leakage of self loading mixer truck:

1. 重視襯墊作用，車輛的零件之間的襯墊是有防漏密封作用的，那如果這些材料在質(zhì)量上或安裝工藝上不符合技術(shù)要求，那就起不到密封防漏的作用，甚會發(fā)生事故，比如油底殼或氣門罩蓋，由于接觸面積大而不易壓實(shí)，就會造成漏油。

1. Pay attention to the role of gasket. The gasket between the parts of the vehicle has the function of leak proof and sealing. If these materials do not meet the technical requirements in quality or installation process, they will not play the role of sealing and leak proof, and even accidents will occur. For example, the oil pan or valve cover is not easy to be compacted due to large contact area, which will cause oil leakage.

2. 自上料攪拌車上的各個(gè)螺母要按規(guī)定扭矩?cái)Q緊，過松壓不緊襯墊會滲漏，過緊會使螺孔周圍金屬凸起或?qū)⒔z扣寧滑而引起漏油。還有就是如果油底殼螺塞未擰緊或脫落，就很容易造成機(jī)油流失。

2. The nuts on the self feeding mixer should be tightened according to the specified torque. If it is too loose or not tight, the gasket will leak. If it is too tight, the metal around the screw hole will bulge or the screw thread will be smooth, causing oil leakage. Also, if the oil pan plug is not tightened or falls off, it is easy to cause oil loss.

3. 要及時(shí)更換失效的油封，自上料攪拌車隨著使用年限的加長，車上很多部位都要注意，有些油封使用時(shí)間長了就會因老化而失去彈性，就很可能因此產(chǎn)生漏油現(xiàn)象。

3. It is necessary to replace the failed oil seal in time. As the service life of the self feeding mixer increases, many parts of the truck should be paid attention to. Some oil seals will lose their elasticity due to aging after a long time of use, which is likely to cause oil leakage.

4. 避免單向閥、通氣閥堵死。由此引起箱殼內(nèi)溫度升高，油氣充滿整個(gè)空間，排放不出去，是箱殼內(nèi)壓力升高潤滑油消耗增加和更換周期縮短。發(fā)動(dòng)機(jī)通氣系統(tǒng)堵塞后，增加了活塞的運(yùn)動(dòng)阻力，使油耗增加。由于箱殼內(nèi)外氣壓差的作用，往往會引起密封薄弱處漏油。因此需要對車輛進(jìn)行定期檢查、疏通、清洗。

4. Avoid blocking the check valve and vent valve. As a result, the temperature in the tank increases, the oil and gas fill the whole space and cannot be discharged. The pressure in the tank increases, the consumption of lubricating oil increases and the replacement period shortens. After the engine ventilation system is blocked, the movement resistance of the piston is increased and the fuel consumption is increased. Due to the effect of the air pressure difference inside and outside the box shell, oil leakage often occurs at the weak part of the seal. Therefore, it is necessary to inspect, dredge and clean the vehicles regularly.

5. 妥善各類油管接頭的密封，對于車輛上經(jīng)常拆裝的螺母要經(jīng)常檢查，發(fā)現(xiàn)問題要及時(shí)更換。

5. Properly solve the sealing of all kinds of oil pipe joints, check the nuts that are often disassembled on the vehicle, and replace them in time if any problem is found.

6.避免輪轂甩油。輪轂軸承及腔內(nèi)潤滑油脂過多，或其油封裝配不妥，質(zhì)量不良或老化失效，制動(dòng)頻繁引起的輪轂溫度過高；車軸螺母松動(dòng)等都會引起輪轂甩油。因此潤滑要適量。

6. Avoid hub oil spilling. Too much lubricating grease in the hub bearing and cavity, or improper matching of oil package, poor quality or aging failure, too high hub temperature caused by frequent braking, and loose axle nut will cause hub oil rejection. Therefore, proper lubrication is required.
