全自動攪拌車拌筒停轉(zhuǎn)故障的分析
全自動攪拌車廠家根據(jù)全自動攪拌車的特點，發(fā)生拌筒不旋轉(zhuǎn)、無法排出砼的故障，主要是由以下幾種原因造成的：
According to the characteristics of the fully automatic mixer, the manufacturer of the fully automatic mixer has the failure that the mixing drum does not rotate and the concrete cannot be discharged, which is mainly caused by the following reasons:
①減速機發(fā)生故障；②液壓馬達發(fā)生故障；③發(fā)動機或液壓油泵發(fā)生故障。根據(jù)我公司的售后服務(wù)情況來看，拌筒不旋轉(zhuǎn)、排不出砼的故障是少出現(xiàn)的。許多用戶由于沒有經(jīng)驗，遇到類似情況往往不知如何處理，容易造成不必要的損失。主要介紹如何正確處置這類故障。
① The reducer fails; ② The hydraulic motor fails; ③ The engine or the hydraulic oil pump has failed. According to the after-sales service of our company, the failure that the mixing drum does not rotate and cannot discharge concrete is rare. Because many users have no experience, they often do not know how to deal with similar situations, which is easy to cause unnecessary losses. This paper mainly introduces how to correctly handle such failures.
如果只有單臺攪拌車在現(xiàn)場作業(yè)，沒有其他相同配置的車輛，或是沒有備有應(yīng)急管，不論是何種原因造成的拌筒停轉(zhuǎn)故障，都只能采取人工的方法排出砼。具體操作方法：
If only a single mixer truck is working on the site, there is no other vehicle with the same configuration, or there is no emergency pipe, no matter what reason the mixer drum stops running, the concrete can only be discharged manually. Specific operation method:
將操作手柄轉(zhuǎn)到中位，使液壓油泵不能再產(chǎn)生高壓油；將發(fā)動機熄火，在確保液壓系統(tǒng)已經(jīng)卸壓的情況下旋松馬達或減速機上的高壓油管，推動拌筒旋轉(zhuǎn)，使拌筒檢修孔斜向下；
Turn the operating handle to the middle position, so that the hydraulic oil pump can no longer produce high-pressure oil; Turn off the engine, unscrew the high-pressure oil pipe on the motor or reducer under the condition that the hydraulic system has been depressurized, and push the mixing drum to rotate so that the mixing drum manhole is inclined downward;
打開攪拌筒檢修孔蓋，將砼從攪拌筒檢修孔用人工的方法排出。旋松高壓油管及清理砼時在托輪和拌筒滾道間放入木楔，確保攪拌筒不能轉(zhuǎn)動，否則拌筒可能因筒體內(nèi)砼位置變化造成突然轉(zhuǎn)動而產(chǎn)生危險。
Open the manhole cover of the mixing drum and discharge the concrete from the manhole of the mixing drum manually. When loosening the high-pressure oil pipe and cleaning the concrete, put wooden wedges between the supporting wheel and the mixing drum raceway to ensure that the mixing drum cannot rotate, otherwise the mixing drum may rotate suddenly due to the change of the concrete gravity center position in the drum, which may cause danger.
若用戶使用相同液壓配置的攪拌車在2臺以上，并備有應(yīng)急管，采取何種方法排出砼，應(yīng)視具體情況而定：
If the user uses more than 2 mixers with the same hydraulic configuration and is equipped with emergency pipes, the method to discharge concrete shall be determined according to the specific situation:
①若是減速機發(fā)生了故障，則只能采用人工方法排出砼，方法同前；
① If the reducer fails, the concrete can only be discharged manually, the method is the same as before;
②若是馬達發(fā)生了故障，可將其他車上馬達卸下，替換故障車上的馬達并按原來的油管聯(lián)接位置接好，啟動發(fā)動機使油泵工作，即可操縱手柄排出砼；
② If the motor fails, remove the other motor on the vehicle, replace the motor on the failed vehicle and connect it according to the original oil pipe connection position. Start the engine to make the oil pump work, and then the handle can discharge the concrete;
③若是發(fā)動機不能啟動，應(yīng)先判斷如能重新將發(fā)動機啟動起來，并可以工作一定的時間，則先將發(fā)動機啟動，排出砼后再進行故障的檢修。
③ If the engine cannot be started, it should be judged first that if the engine can be restarted and can work for a certain period of time, the engine should be started first, and the troubleshooting should be carried out after the concrete is discharged.
在實際運用中，由于每一個用戶對自動上料攪拌車所掌握的情況不同，因此需視具體情況參照以上的方法進行操作，以快速度排出砼，以免延誤時間，造成不必要的損失。更多相關(guān)事項就來我們網(wǎng)站http://www.zvmc.cn咨詢吧！
In practical application, because each user has different information about the automatic feeding mixer, it is necessary to refer to the above methods according to the specific situation, and discharge the concrete at a fast speed, so as to avoid delay and unnecessary loss.
