The automatic concrete mixer must be well known to all. Automatic concrete mixer is used in many places, and automatic concrete mixer also plays a very important role. When using a small mixer track such as a mixer track, a corresponding problem always occurs.

一些小型搅拌车司机报告说，如果他们与朋友同时购买同一辆搅拌车，他们在使用汽车一段时间后会遇到发动机问题，但是他们朋友的汽车的发动机很好。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。

Some small mixer drivers report that if they buy the same mixer with their friends at the same time, they will encounter engine problems after using the car for a period of time, but their friends' car engine is very good. 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.自动混凝土搅拌车上的维护数据使用不当

1. Improper use of maintenance data on automatic concrete mixer

在自动混凝土搅拌车的维护中，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，在进气门的情况下，气门与阀座之间的接触面的宽度为1.2.2mm，在排气门的情况下，宽度为1.5.2.5mm。，但在实际维护中，宽度是变大和变窄，应该大于。

In the maintenance of automatic concrete mixer, the failure to select maintenance data scientifically is an important reason for premature damage of parts. For example, in the case of inlet valve, the width of the contact surface between valve and valve seat is 1.2.2mm, and in the case of exhaust valve, the width is 1.5.2.5mm., However, in actual maintenance, the width becomes larger and narrower, which should be greater than.

许多人说这很好，通常将上限选择为上限或接近上限。新车的气门工作面宽度已经接近使用限度，因此是上限。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，维护调整认为差距要大于较小的差距。因此，如果间隙超过上限，则间隙实际上会变得太大，不仅降低了发动机功率，而且还由于冲击而引起了初始损坏。

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 new car is close to the use limit, so it 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 believes that the gap is larger than the smaller gap. Therefore, if the gap exceeds the upper limit, the gap will actually become too large, which not only reduces the engine power, but also causes initial damage due to impact.

2.平稳地压碎自动混凝土搅拌车的阀门

2. Crush the valve of the automatic concrete mixer smoothly

如果阀门有消融，凹坑或凹痕以保持小型搅拌车，则通常需要使用抛光研磨机对其进行研磨。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。

If the valve has ablation, pits or dents to maintain a small mixer, it usually needs to be ground 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, suppose you can polish the 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.
