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 reported that buying the same mixer at the same time with friends would cause engine problems after using the car for a period of time, but the engine in friends' cars was very good. Why did the mixer engine break so quickly? The manufacturer of full-automatic concrete mixer let us see if it is used improperly or there is a problem with the vehicle itself.

1.混凝土搅拌车的维护数据使用不当

1. Improper use of maintenance data of concrete mixer

在搅拌车的维护中，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。

In the maintenance of 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.

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。

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.平稳地压碎混凝土搅拌车的阀门

2. Crush the valve of the concrete 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, 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.
