Self feeding mixer is an essential equipment in engineering construction. However, due to its automatic setting, some functions will affect the overall use after a long time of use. The following is a brief introduction to the weaknesses of self feeding mixer

，齒輪箱的正常壓力范圍為1.08~1.47MPa，壓力低于1.08MPa。認(rèn)為變速油壓太低，這將導(dǎo)致自上料攪拌車的驅(qū)動力不足，整機(jī)弱，齒輪不起動。

Firstly, the normal pressure range of the gearbox is 1.08 ~ 1.47mpa, and the pressure is lower than 1.08mpa. It is considered that too low transmission oil pressure will lead to insufficient driving force of self feeding mixer, weak whole machine and gear not starting.

減壓閥的功能是通過壓力調(diào)節(jié)彈簧將較高的輸入壓力調(diào)節(jié)到規(guī)定的輸出壓力，并確保輸出壓力的平衡。一旦減壓閥的壓力調(diào)節(jié)彈簧損壞，變速箱將不能保證正常的輸出壓力。

The function of the pressure reducing valve is to adjust the higher input pressure to the specified output pressure through the pressure regulating spring and ensure the balance of the output pressure. Once the pressure regulating spring of the pressure reducing valve is damaged, the transmission will not guarantee the normal output pressure.

其次，壓力調(diào)節(jié)器沒有適當(dāng)調(diào)整

Second, the pressure regulator is not properly adjusted

壓力調(diào)節(jié)閥通過壓力調(diào)節(jié)閥芯控制變速器的輸出壓力。如果輸出壓力太小，變速箱油壓將太低。

The pressure regulating valve controls the output pressure of the transmission through the pressure regulating valve core. If the output pressure is too low, the transmission oil pressure will be too low.

三是管道油封嚴(yán)重漏油。

The third is the serious oil leakage of pipeline oil seal.

檢查變速箱油盤到變速箱泵吸入管路是否泄漏。如果發(fā)現(xiàn)漏油，請修理或更換新線路。

Check the transmission oil pan to transmission pump suction line for leakage. If oil leakage is found, repair or replace the circuit.

自上料攪拌車驅(qū)動器介紹

Introduction of self loading mixer driver

1.通用車削部件是故障部件。應(yīng)及時填充潤滑脂，并經(jīng)常檢查磨損情況，及時修理和更換。車隊(duì)?wèi)?yīng)該有一個備用的萬向軸組件，以確保在發(fā)生故障時能夠在幾分鐘內(nèi)恢復(fù)。

1. General turning parts are fault parts. Grease should be filled in time, and the wear should be checked frequently, repaired and replaced in time. The fleet should have a spare cardan shaft assembly to ensure recovery in a few minutes in the event of a failure.

2.確保液壓油清潔。自上料攪拌車的工作環(huán)境不好，必須防止臟水泥砂進(jìn)入液壓系統(tǒng)。應(yīng)根據(jù)手冊的要求定期更換液壓油。一旦檢查發(fā)現(xiàn)水或沙子混入液壓油中，就必須立即停止液壓系統(tǒng)并更換液壓油。

2. Make sure the hydraulic oil is clean. The working environment of the self feeding mixer is not good, so it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil should be changed regularly according to the manual. Once water or sand is found mixed in the hydraulic oil, the hydraulic system must be stopped immediately and the hydraulic oil must be replaced.

3.確保液壓油冷卻裝置有效。定期清洗液壓油散熱器，避免散熱器被水泥堵住，檢查散熱器電風(fēng)扇是否正常運(yùn)行，防止液壓油溫度超標(biāo)。只要液壓部件確保液壓油清潔，通常幾乎沒有故障，但制造商具有不同的使用壽命。

3. Ensure that the hydraulic oil cooling device is effective. Regularly clean the hydraulic oil radiator to avoid the radiator being blocked by cement, check whether the radiator fan is in normal operation, and prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic components ensure that the hydraulic oil is clean, there are usually few failures, but manufacturers have different service lives.

一般來說，如果驅(qū)動裝置由于故障停止工作，混凝土儲罐將不能正常旋轉(zhuǎn)，這將導(dǎo)致車輛中的混凝土報(bào)廢，甚整個罐體混凝土將在罐內(nèi)冷凝，造成自上料攪拌車要報(bào)廢。因此，驅(qū)動裝置是否可靠是在使用中必須高度重視的問題。

Generally speaking, if the driving device stops working due to fault, the concrete tank will not rotate normally, which will lead to the scrapping of the concrete in the vehicle, or even the whole tank concrete will condense in the tank, resulting in the scrapping of the self loading mixer. Therefore, whether the driving device is reliable or not is a problem that must be attached great importance in use.
