小型混凝土搅拌车卸完料后，卸了料门关闭，但无关门信号，造成程序停止运行，这是怎么回事呢？又该如何来呢？

After unloading of small concrete mixer truck, the unloading door is closed, but there is no door closing signal, causing the program to stop running. What is the matter? How to solve it?

小型混凝土搅拌车卸料门接近开关与卸料门上的转柄指针接近距离不超过5mm才能感应信号。当卸料门因油泵压力未达到要求或卸料门在关闭时被小型混凝土搅拌车里的残料卡住时，接近开关接近不到转柄指针而没有信号，因接近开关或转柄指针松动，使接近距离超过5mm时，接近开关也感应不到信号。如接近开关损坏也没有信号输出。

The proximity switch of the discharge door of the small concrete mixer truck can sense the signal only when the proximity distance between the rotary handle pointer on the discharge door is no more than 5mm. When the discharge door fails to meet the requirements due to the pressure of the oil pump or the discharge door is stuck by the residues in the small concrete mixer truck when it is closed, the proximity switch cannot reach the rotary handle pointer and has no signal. When the proximity switch or the rotary handle pointer is loose, the proximity switch cannot sense the signal when the proximity distance exceeds 5 mm. If the proximity switch is damaged, there is no signal output.

处理过程：

Handling process:

1.检查卸料门液压系统工作压力是否达到要求（13Mpa）

1. Check whether the working pressure of the hydraulic system of the discharge door meets the requirements (13Mpa)

2.切换到手动，把小型混凝土搅拌车卸料门打开，使卡住的残料掉落后再关上。

2. Switch to manual mode, open the discharge door of small concrete mixer truck, and close it after the stuck residue falls.

3.检查接近开关和转柄指针是否松动。

3. Check whether the proximity switch and the rotary handle pointer are loose.

4.检查接近开关是否损坏。

4. Check whether the proximity switch is damaged.

小型混凝土搅拌车如果长期闲置停放或封存保管时就需要进行的一种维护保养。保养内容主要是清洁、清洗、润滑、防护等。其目的是预防或减少存放期间各种恶劣条件对机器产生的不良影响，保证车辆经常处于良好的备用状态。

It is a kind of maintenance required for small concrete mixer if it is left idle for a long time or sealed for storage. The maintenance mainly includes cleaning, cleaning, lubrication, protection, etc. Its purpose is to prevent or reduce the adverse effects of various harsh conditions on the machine during storage, and ensure that the vehicle is always in good standby state.
