In the use of the mixer, oil leakage occasionally occurs. If it can not be handled in time, it may lead to early damage of the machine parts, and even leave accident hidden danger. Therefore, we should analyze and investigate the causes of mixer oil leakage to avoid accidents. Next, Xiaobian will give you an analysis of the causes of oil leakage in the mixer.

　　一、搅拌一体机漏油故障原因排查

　　1、 Troubleshooting of oil leakage of mixer1、搅拌机上各类螺母是否拧紧。有时候，搅拌机漏油是因为车用联管螺母松脱。

　　1. Whether all kinds of nuts on mixer are tightened. Sometimes, the mixer leaks oil because the union nut for the vehicle is loose.

　　2、搅拌机漏油也可能是因为密封材料长期使用后磨损过限，老化变质、变形失效。

　　2. The oil leakage of mixer may also be due to excessive wear, aging, deformation and failure of sealing materials after long-term use.

　　3、紧固螺母拧力不均、滑丝断扣或者松旷脱落等也会使工作失效，过松压不紧衬垫会渗漏；过紧又会使螺孔附近金属突出或将丝扣拧滑而引起漏油。?

　　3. Uneven tightening force of fastening nut, broken thread of sliding thread or looseness and falling off will also lead to work failure. If it is too loose and pressed, the gasket will leak; if it is too tight, the metal near the screw hole will protrude or the screw thread will be screwed to cause oil leakage. ?

　　4、是否装配不当，是否表面不清洁，衬垫破损、位移或者未按操纵规程规范进行安装。更换联管螺母，用研磨法其锥面密封，使螺母压紧而密封。如油底壳或气门罩盖，因为接触面积大而不易压实，由此造成漏油，若在材料、制作质量及安装上不符合技术规范，就起不到密封防漏作用，甚发生事故。

　　4. Whether the assembly is improper, whether the surface is not clean, the gasket is damaged, displaced or not installed according to the operation regulations. Replace the union nut, use grinding method to solve the cone sealing, so that the nut is pressed to solve the sealing. For example, the oil pan or valve cover is not easy to be compacted due to its large contact area, resulting in oil leakage. If the material, manufacturing quality and installation do not meet the technical specifications, it will not play a role in sealing and leakage prevention, or even cause accidents.
              

　　5、是否是轮毂甩油。由此引起箱壳内温度升高，油气布满整个空间、排放不出去，使箱壳内压力升高润滑油消耗增加和更换周期缩短。

　　5. Whether it is the hub oil spilling. As a result, the temperature in the case rises, the oil and gas fills the whole space and can not be discharged, so that the pressure in the case increases, the consumption of lubricating oil increases and the replacement period is shortened.

　　6、搅拌一体机上良多动置部位（如油封、Ｏ型圈）会因安装不妥，轴颈与油封刃口不同心，偏摆而甩油。轮毂轴承及腔内润滑油脂过多，或其油封装配不妥，质量不良及老化失效；制动频繁引起的轮毂温渡过高；车轴螺母松动等都会引起轮毂甩油，发现渗漏应及时更新。

　　6. Many moving parts (such as oil seal and O-ring) on the mixer will throw oil due to improper installation, misalignment between journal and oil seal edge, and deflection. Excessive lubricating grease in hub bearing and cavity, or improper oil packaging, poor quality and aging failure; excessive hub temperature caused by frequent braking; loose axle nut, etc., will cause wheel hub oil rejection, and timely update if leakage is found.

　　二、预防搅拌机漏油的五种方法

　　2、 Five methods to prevent oil leakage of mixer1、自上料搅拌机上各类紧固螺母都需按规定的扭矩拧紧，过松压不紧衬垫会渗漏，过紧又会使螺孔周围金属凸起或将丝扣拧滑而引起漏油。另外，油底壳放油螺塞若未拧紧或回松脱落，容易造成机油流失，继而发生“烧瓦抱轴”的机损事故。

　　1. All kinds of fastening nuts on the charging mixer should be tightened according to the specified torque. If the gasket 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 screwed to cause oil leakage. In addition, if the oil drain plug of the oil pan is not tightened or loosened and falls off, it is easy to cause the oil loss, and then cause the mechanical damage accident of "burning bush and holding shaft".

　　2、避免单向阀、通气阀堵死。由此引起箱壳内温度升高，油气充满整个空间、排放不出去，使箱壳内压力升高润滑油消耗增加和更换周期缩短。自上料搅拌机发动机通气系统堵塞后，增加了活塞的运动阻力，使油耗增加。由于箱壳内外气压差的作用，往往会引起密封薄弱处漏油。因此需对自上料搅拌机进行定期检查、疏通、清洗。

　　2. Avoid blocking of one-way valve and ventilation valve. As a result, the temperature in the case rises, the oil and gas fills the whole space and can not be discharged, so that the pressure in the case increases, the consumption of lubricating oil increases and the replacement cycle is shortened. Since the engine ventilation system of the charging mixer is blocked, the movement resistance of the piston is increased and the fuel consumption is increased. Because of the pressure difference between the inside and outside of the case, oil leakage often occurs at the weak part of the seal. Therefore, it is necessary to regularly check, dredge and clean the self feeding mixer.

　　3、重视衬垫作用。自上料搅拌机静置部位零部件之间的衬垫起着防漏密封作用。若在材料、制作质量及安装上不符合技术规范，就起不到密封防漏作用，甚发生事故。如油底壳或气门罩盖，由于接触面积大而不易压实，由此造成漏油。

　　3. Pay attention to the liner function. The gasket between the parts of the static part of the charging mixer plays a leak proof and sealing role. If the material, manufacturing quality and installation do not meet the technical specifications, it will not play a role in sealing and leakage prevention, and even accidents will occur. For example, the oil pan or valve cover is not easy to compact due to its large contact area, resulting in oil leakage.

　　4、及时更换失效油封。自上料搅拌机上很多动置部位会因安装不妥，轴颈与油封刃口不同心，偏摆而甩油，有些油封使用过久会因橡胶老化而失去弹性。发现渗漏应及时更新。

　　4. Replace the invalid oil seal in time. Since many moving parts on the charging mixer are installed improperly, the journal and the oil seal edge are not concentric, and swing and throw oil. Some oil seals will lose elasticity due to rubber aging after being used for a long time. If leakage is found, it should be updated in time.

　　5、避免搅拌机轮毂甩油。自上料搅拌机轮毂轴承及腔内润滑油脂过多，或其油封装配不妥，质量不良及老化失效；自上料搅拌机的制动频繁引起轮毂温度过高；车轴螺母松动等都会引起轮毂甩油，因此要用“空腔润滑法”，疏通通气孔。

　　5. Avoid oil spilling from mixer hub. There are too much lubricating grease in the hub bearing and cavity of the self loading mixer, or the oil package is not properly matched, poor quality and aging failure; the frequent braking of the self loading mixer causes the hub temperature to be too high; the axle nut looseness will cause the wheel hub to throw oil, so "cavity lubrication method" should be used to dredge the air hole.
