The automatic concrete mixer must be well known to everyone. Automatic concrete mixer is used in many places, automatic concrete mixer also plays a very important role. When using small mixer tracks such as mixer tracks, there are always corresponding problems.

一些小型攪拌車司機報告說，如果他們與朋友同時購買同一輛攪拌車，他們在使用汽車一段時間后會遇到發動機問題，但是他們朋友的汽車的發動機很好。發生了什么？混合器引擎為什么會這么快破裂？讓我們看看是否使用不當或車輛本身有問題。

Some small mixer drivers report that if they buy the same mixer with a friend at the same time, they will encounter engine problems after using the car for a period of time, but their friend's car has a good engine. What happened? Why did the mixer engine break down so quickly? Let's see if it's not used properly or if there's something wrong with the vehicle itself.

1.自動混凝土攪拌車上的維護數據使用不當

1. Improper use of maintenance data on automatic concrete mixer

在自動混凝土攪拌車的維護中，無法科學地選擇維護數據是零件過早損壞的重要原因。例如，在進氣門的情況下，氣門與閥座之間的接觸面的寬度為1.2.2mm，在排氣門的情況下，寬度為1.5.2.5mm。，但在實際維護中，寬度是變大和變窄，應該大于。許多人說這很好，通常將上限選擇為上限或接近上限。

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 intake valve, the width of contact surface between valve and valve seat is 1.2.2mm, in the case of exhaust valve, the width is 1.5.2.5mm., But in the actual maintenance, the width is larger and narrower, should be greater than. Many people say that's good, and usually choose the upper limit as the upper limit or close to the upper limit.

新車的氣門工作面寬度已經接近使用限，因此是上限。另一個例子是閥腳間隙。車輛通常指定為0.2-0.25毫米。但是，維護調整認為差距要大于較小的差距。因此，如果間隙超過上限，則間隙實際上會變得太大，不僅降低了發動機功率，而且還由于沖擊而引起了初始損壞。

The width of the valve working surface of the new car is close to the service 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 greater than the smaller gap. Therefore, if the clearance exceeds the upper limit, the clearance will actually become too large, which not only reduces the engine power, but also causes initial damage due to impact.

2.平穩地壓碎自動混凝土攪拌車的閥門

2. Crush the valve of automatic concrete mixer smoothly

如果閥門有消融，凹坑或凹痕以保持小型攪拌車，則通常需要使用拋光研磨機對其進行研磨。在操作過程中要注意四個問題。首先，檢查閥頭和閥桿。同心圓，否則您需要先修復它們。接下來，假設您可以拋光完 美的圓錐，則需要使光滑的汽車盡可能小。接下來，您需要進行表面拋光。第四方面應盡可能提高以平滑閥桿的凹入端。

If the valve has ablation, pits or dents to keep the 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, 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 stem.
