Mixer truck is a truck used to transport concrete for construction; Because of its shape, it is often called snail car and olive car.

这类卡车上都装置圆筒型的搅拌筒以运载混合后的混凝土。在运输过程中会始终保持搅拌筒转动，以保证所运载的混凝土不会凝固。

Such trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum will always rotate to ensure that the transported concrete will not solidify.

运送完混凝土后，通常都会用水冲洗搅拌筒内部，防止残余混凝土硬化占用空间，使搅拌筒的容积越来越少。

After the concrete is transported, the interior of the mixing drum is usually washed with water to prevent the residual concrete from hardening and occupying space, so as to reduce the volume of the mixing drum.

全自动上料搅拌车，一机多用，性能，搅拌筒结构紧凑，密封性好，并在进料口设置挡火板，防止水雾反串。

The fully automatic feeding mixer has multi-purpose, advanced performance, compact structure and good sealing of the mixing drum, and a fire baffle is set at the feed inlet to prevent the reverse string of water mist.

调音台轨道必须为所有人所熟知。搅拌车被用在很多地方，搅拌车也起着非常重要的作用。当使用小的混合器轨道，例如混合器轨道时，总是出现相应的问题。一些小型搅拌车司机报告说，与朋友在同一时间购买同一辆搅拌车在使用汽车一段时间后会导致引擎问题，但是朋友车中的引擎很好。 ..发生了什么？发生了什么？混合器引擎为什么会这么快破裂？让我们看看是否使用不当或车辆本身有问题。

The mixer track must be well known to all. Mixer truck is used in many places, and mixer truck also plays a very important role. When using small mixer tracks, such as mixer tracks, corresponding problems always occur. Some small mixer drivers report that buying the same mixer at the same time with friends will cause engine problems after using the car for a period of time, but the engine in friends' cars is very good What happened? What happened? Why did the mixer engine break so quickly? Let's see if it's not used properly or if there's a problem with the vehicle itself.

1.小型搅拌车的维护数据使用不当

1. Improper use of maintenance data of small mixer

在小型搅拌车的维护中，无法科学地选择维护数据是零件过早损坏的重要原因。例如，对于进气门，气门与气门座之间的接触表面的宽度指定为1.2.2毫米，对于排气门，规定为1.5.2.5毫米，但是在实际维护中，该宽度大于较大的宽度。需要这样做。宽度很窄。许多人说这很好，通常将上限选择为上限或接近上限。新修汽车的阀门工作表面的宽度已经接近其使用极限，因此这是上限。另一个例子是阀脚间隙。车辆通常指定为0.2-0.25毫米。但是，维护调整认为该间隙大于较小的间隙。因此，如果间隙超过上限，则间隙实际上太大，这不仅降低了发动机功率，而且由于冲击而引起了初始损坏。

In the maintenance of small mixer truck, the failure to select maintenance data scientifically is an important reason for premature damage of parts. For example, the width of the contact surface between the valve and the valve seat is specified as 1.2.2 mm for the inlet valve and 1.5.2.5 mm for the exhaust valve, but in actual maintenance, the width is greater than the larger width. This needs to be done. The width is very narrow. Many people say this is good, and usually choose the upper limit as the upper limit or close to the upper limit. The width of the valve working surface of the newly repaired vehicle is close to its service limit, so this is the upper limit. Another example is the valve foot clearance. Vehicles are usually specified as 0.2-0.25 mm. However, the maintenance adjustment considers that the clearance is larger than the smaller clearance. Therefore, if the gap exceeds the upper limit, the gap is actually too large, which not only reduces the engine power, but also causes initial damage due to impact.

2.平稳地压碎小型搅拌车的阀门

2. Crush the valve of the small mixer smoothly

为了保持较小的混合器轨迹，如果阀门有消融，凹坑或凹痕，通常需要使用抛光研磨机对其进行抛光。在操作过程中要注意四个问题。，检查阀头和阀杆。同心圆，否则您需要先修复它们。接下来，假设您可以抛光的圆锥，则需要使光滑的汽车尽可能小。接下来，您需要进行表面抛光。第四方面应尽可能提高以平滑阀杆的凹入端。

In order to maintain a small mixer trajectory, if the valve has ablation, pits or dents, it usually needs to be polished with a polishing grinder. In the process of operation, we should pay attention to four problems. First, check the valve head and stem. Concentric circles, otherwise you need to fix them first. Next, assuming you can polish the perfect cone, you need to make the smooth car as small as possible. Next, you need to polish the surface. The fourth aspect should be raised as much as possible to smooth the concave end of the valve stem.
