There is no solution to the problem of cement mixer? Can only watch the concrete solidify, how anxious it is. But now you don't have to worry, because the cement self loading mixer manufacturer 2 has customized a set of solutions for you. With it, you don't have to worry about accidents anymore!

一、罐體轉(zhuǎn)動工作原理

1、 Working principle of can body rotation

發(fā)動機取力器——傳動軸——油泵——馬達——減速機——罐體轉(zhuǎn)動

Engine power takeoff - transmission shaft - oil pump - motor - reducer - can body rotation

二、原因分析

2、 Cause analysis

導(dǎo)致攪拌罐停轉(zhuǎn)主要有以下原因：

The shutdown of mixing tank is mainly caused by the following reasons:

1.發(fā)動機故障：發(fā)動機無法啟動、取力器損壞等原因。

1. Engine failure: the engine cannot be started, the power take-off is damaged, etc.

2.上裝故障：傳動軸損壞、油泵故障、液壓油過臟或油量不足、馬達故障、減速機故障、操縱桿松脫等原因。

2. Mounting failure: transmission shaft damage, oil pump failure, dirty or insufficient hydraulic oil, motor failure, reducer failure, control lever loosening, etc.

三、尋找故障點

3、 Find the fault point

當車輛運送混凝土過程中，發(fā)生罐體無法轉(zhuǎn)動故障，應(yīng)停車進行檢查。通過“一聽、一看、一動”迅速尋找故障點，“一聽”是指從傳動軸到減速機各零部件有無發(fā)出異響；“一看”是指看液壓油箱油位是否過低或管路漏油嚴重；“一動”是指前后扳動油泵伺服桿，罐體是否正反均無轉(zhuǎn)動。

When the tank fails to rotate during concrete transportation, the vehicle shall be stopped for inspection. Quickly find the fault point by "listening, looking and moving", and "listening" refers to whether all parts from the transmission shaft to the reducer make abnormal noise; "One look" means to check whether the oil level of the hydraulic oil tank is too low or the pipeline leaks seriously; "Movement" refers to pulling the oil pump servo rod back and forth, and whether the tank body does not rotate in both positive and negative directions.

注：應(yīng)在罐體停止轉(zhuǎn)動后當即聯(lián)系當?shù)胤?wù)人員（附通訊錄），告知罐內(nèi)混凝土標號及預(yù)凝時間，服務(wù)人員會耐心指導(dǎo)您如何處理，同時請您將車輛開就近服務(wù)站。

Note: after the tank stops rotating, immediately contact the local service personnel (with address book) to inform the concrete grade and pre setting time in the tank. The service personnel will patiently guide you how to deal with it. At the same time, please drive the vehicle to the nearest service station.

四、應(yīng)急措施

4、 Emergency measures

如果不能在混凝土預(yù)凝之前將車輛修復(fù)，應(yīng)立即采取應(yīng)急措施：

If the vehicle cannot be repaired before the concrete is pre set, emergency measures shall be taken immediately:

1.馬達和減速機無故障情況下，連接“應(yīng)急油管”將混凝土卸出，預(yù)防凝灌事故發(fā)生。

1. Connect the "emergency oil pipe" to unload the concrete when the motor and reducer have no fault, so as to prevent concreting accident.

2.馬達或減速機發(fā)生故障且確定無法在混凝土預(yù)凝前使罐體轉(zhuǎn)動，請快速打開人孔蓋，如人孔蓋不在罐體下方則需要在罐體前錐底部開孔（Φ=1250px，避開原有焊道），與此同時持續(xù)向進料口灌入大量清水，沖刷罐內(nèi)混凝土，直罐體下方無混凝土流出，罐內(nèi)少量殘余混凝土需人工進行清理，清理完畢后進行清洗，將割下部分重新焊接到罐體上（安裝人孔蓋），并打磨噴漆處理。

2. If the motor or reducer fails and it is determined that the tank cannot rotate before the concrete is pre set, please quickly open the manhole cover. If the manhole cover is not below the tank, you need to open a hole at the bottom of the front cone of the tank（ Φ= 1250px, avoiding the original weld bead), and at the same time, continuously pour a large amount of clean water into the feed inlet to wash the concrete in the tank until no concrete flows out under the tank. A small amount of residual concrete in the tank needs to be cleaned manually. After cleaning, the cut part shall be welded to the tank again (manhole cover shall be installed), and polished and painted.
