小型混凝土攪拌車(chē)卸完料后，卸了料門(mén)關(guān)閉，但無(wú)關(guān)門(mén)信號，造成程序停止運行，這是怎么回事呢？又該如何來(lái)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?
原因分析：
Cause analysis:
小型混凝土攪拌車(chē)卸料門(mén)接近開(kāi)關(guān)與卸料門(mén)上的轉柄指針接近距離不超過(guò)5mm才能感應信號。當卸料門(mén)因油泵壓力未達到要求或卸料門(mén)在關(guān)閉時(shí)被小型混凝土攪拌車(chē)里的殘料卡住時(shí)，接近開(kāi)關(guān)接近不到轉柄指針而沒(méi)有信號，因接近開(kāi)關(guān)或轉柄指針松動(dòng)，使接近距離超過(guò)5mm時(shí)，接近開(kāi)關(guān)也感應不到信號。如接近開(kāi)關(guān)損壞也沒(méi)有信號輸出。
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.
處理過(guò)程：
Handling process:
1.檢查卸料門(mén)液壓系統工作壓力是否達到要求（13Mpa）
1. Check whether the working pressure of the hydraulic system of the discharge door meets the requirements (13Mpa)
2.切換到手動(dòng)，把小型混凝土攪拌車(chē)卸料門(mén)打開(kāi)，使卡住的殘料掉落后再關(guān)上
2. Switch to manual mode, open the discharge door of small concrete mixer truck, and close it after the stuck residue falls
3.檢查接近開(kāi)關(guān)和轉柄指針是否松動(dòng)
3. Check whether the proximity switch and the rotary handle pointer are loose
4.檢查接近開(kāi)關(guān)是否損壞
4. Check whether the proximity switch is damaged
小型混凝土攪拌車(chē)如果長(cháng)期閑置停放或封存保管時(shí)就需要進(jìn)行的一種維護保養。保養內容主要是清潔、清洗、潤滑、防護等。其目的是預防或減少存放期間各種惡劣條件對機器產(chǎn)生的不良影響，保證車(chē)輛經(jīng)常處于良好的備用狀態(tài)。
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.
