What are the main reasons for oil leakage of concrete mixer?

1产品（配件）质量材质或工艺不佳；结构设计存在问题。

1. Poor quality, material or process of products (accessories); There are problems in structural design.

装配高速不当，配合表面不清洁，衬垫破损位移或未按操作规程规范进行安装。

Improper assembly speed, unclean mating surface, damaged gasket, displacement or failure to install according to the operating procedures.

紧固螺母拧力不均滑丝断扣或松旷脱落等导致工作失效。

Uneven tightening force of fastening nut, broken thread of sliding wire or loose falling off, resulting in work failure.

密封材料长期使用后磨损过限，老化变质变形失效。

After long-term use, the sealing material is worn out, aged, deteriorated, deformed and invalid.

润滑油添加过多油面过高或加错油品。

The lubricating oil is added too much, the oil level is too high or the wrong oil is added.

罐车部件（边盖类薄壁件）接合表面挠曲变形壳体破损，使润滑油渗出。

The joint surface of tank car parts (side cover thin-walled parts) is flexed and deformed, and the shell is damaged, causing lubricating oil to seep out.

罐车通气塞单向阀堵塞后，由于箱壳内外气压差的作用，往往会引起密封薄弱处漏油。

After the one-way valve of the tank car vent plug is blocked, oil leakage at the weak seal will often be caused due to the effect of the air pressure difference inside and outside the tank shell.

小型全自动水泥搅拌车的阀体检修在整个工程作业中也是重要的，做好基本的检修我们的工作才能正常进行。将一张#600的砂纸置于atf油中，浸泡约30分钟。小心地敲击阀体，使卡滞的阀杆从阀腔孔中落下。可能有使用一把小螺丝刀，将其撬出。

The maintenance of the valve body of the small automatic cement mixer is also important in the whole project operation. Only by doing the basic maintenance well can our work be carried out normally. Soak a piece #600 of sandpaper in ATF oil for about 30 minutes. Carefully tap the valve body to make the stuck valve stem fall from the valve cavity hole. A small screwdriver may be used to pry it out.

使用螺丝刀时，小心不要划阀孔。单向阀杆是否有摩擦痕迹。使用atf油浸泡过的#600砂纸，打磨阀杆上的毛刺，然后在溶剂中清洗阀杆并用压缩空气吹干。卷起半张atf油浸泡过的#600砂纸，将其卡滞阀杆的阀孔中。轻轻扭动砂纸，使砂纸松卷，紧密贴合在阀孔表面，然后边推拉，边扭卷砂纸，打磨阀孔。抽出#600砂纸。在溶剂中清洗整个阀体，然后用压缩空气吹干。在阀杆表面涂atf油，然后将其落入阀孔中。阀杆应能靠自重落入阀孔底部。否则，重复步骤4，重新测试。如果阀杆仍然卡滞，则换阀体。取出小型全自动混泥土搅拌车阀杆，用溶剂清理阀杆和阀体。用压缩空气吹干，然后用atf油作为润滑剂，重新组装。

When using a screwdriver, be careful not to scratch the valve hole. Check whether the one-way valve stem has friction marks. Use the #600 sandpaper soaked in ATF oil to polish the burrs on the valve stem, then clean the valve stem in solvent and blow dry with compressed air. Roll up half a piece of #600 sandpaper soaked in ATF oil and clamp it in the valve hole of the valve stem. Gently twist the sandpaper to make it loose and tightly fit on the surface of the valve hole, and then twist the sandpaper while pushing and pulling to polish the valve hole. Draw out #600 sandpaper. Clean the whole valve body in solvent and blow dry with compressed air. Coat the surface of the valve stem with ATF oil and drop it into the valve bore. The valve stem shall fall into the bottom of the valve hole by its own weight. Otherwise, repeat step 4 and retest. If the valve stem is still stuck, replace the valve body. Take out the valve rod of small automatic concrete mixer, and clean the valve rod and valve body with solvent. Blow dry with compressed air, then reassemble with ATF oil as lubricant.

了解了以上的检修知识，大家可以放心对我们的设备进行检修，大家在选择说这些产品的时候我们会有的人士为大家解答，建议大收工时，要清洗混凝土贮罐及进出料口周围，不粘有水泥及混凝土结块。

After knowing the above maintenance knowledge, you can rest assured to repair our equipment. When you choose to say these products, some people will answer for you. It is suggested to clean the concrete storage tank and around the inlet and outlet without cement and concrete caking at the end of work.

固定式混凝土搅拌机，应安装在的台座上。当长期使用时，应埋置地脚螺栓；如短期使用，可在机座下铺设枕木并找平放稳。 3对于移动式混凝土搅拌机，应安装在平坦坚硬的地坪上用方木或撑架架牢，并保持水平面轮胎不受力。如果使用时间三个月以上时，应将轮胎卸下妥善保管轮轴端部应做好清洁锈工作。

The fixed concrete mixer shall be installed on the pedestal of the. In case of long-term use, anchor bolts shall be embedded; For short-term use, sleepers can be paved under the base, leveled and placed stably. 3. The mobile concrete mixer shall be installed on a flat and hard floor, firmly supported with square timber or support, and the tire on the horizontal plane shall not be stressed. If it is used for more than three months, remove the tire and keep it properly. The end of the axle shall be cleaned.

对某些需要挖设上料斗地坑的搅拌机，其坑口周围应垫高夯实，地面水流入坑内。上料轨道架的底端支承面应夯实或铺砖架的后面亦须用木料加以支承，工作时轨道变形。

For some mixers that need to dig a hopper pit, the pit mouth shall be padded and compacted, and the ground water flows into the pit. The bottom bearing surface of the loading track frame shall be compacted or paved with bricks, and the back of the frame shall also be supported with wood, so the track will be deformed during operation.

混凝土搅拌机启动后，应使搅拌筒达到正常转速后进行上料，上料后要及时加水；添加新料先将搅拌机内原有的混凝土卸出后才能进行。不得中途停机或满载荷时起动搅拌机，反转出料者除外。

After the concrete mixer is started, the mixing drum shall reach the normal speed before feeding, and water shall be added in time after feeding; Adding new materials can be carried out only after the original concrete in the mixer is unloaded. Do not stop halfway or start the mixer at full load, except for reverse discharge.

在混凝土搅拌机使用中，切勿使砂石落入机器运转部分中去，以免使运转部件卡住损坏。上料斗后，斗下不能有人通过或停留，以免制动器发生意外事故。在斗下检修或进行清理工作时，强行停机并将上料斗用保险链条拉牢。

During the use of the concrete mixer, do not let the sand fall into the running part of the machine, so as to avoid jamming and damage to the running parts. After loading the hopper, no one can pass or stay under the hopper to avoid accidents of the brake. When overhauling or cleaning under the bucket, forcibly stop the machine and fasten the upper hopper with a safety chain.

搅拌机作业中，如发现故障不能继续运转时，应切断电源，将搅拌筒内的混凝土干净，然后进行检修。

During the operation of the mixer, if it is found that the failure cannot continue to operate, the power supply shall be cut off, the concrete in the mixing drum shall be cleaned, and then the maintenance shall be carried out.

作业后，应对搅拌机进行清洗，操作人员如需要进入筒内清洗时，切断电源，设专人在外监护，或卸去熔断器并锁好电闸箱，然后方可进入。

After operation, the mixer shall be cleaned. If the operator needs to enter the barrel for cleaning, cut off the power supply, assign a special person to monitor outside, or remove the fuse and lock the switch box before entering.

搅拌机上料斗的摇把，应用销子固定，以免人进入简内清理时，身体碰触摇把使料斗，发生挤压事故。

The handle of the hopper on the mixer shall be fixed with a pin to prevent people from touching the handle and squeezing the hopper when entering the Jane for cleaning.

作业后，应将搅拌机料斗降落到料斗坑，如需升起则应用链条扣牢

After operation, the mixer hopper shall be lowered to the hopper pit. If it needs to be raised, it shall be fastened with a chain
