混凝土全自動攪拌車的發動機出現故障是經常會發生的一種情況,那么如何判斷發動機要大修呢?
The engine failure of automatic concrete mixer is a common situation, so how to judge whether the engine needs to be overhauled?
1,氣缸內徑過度磨損。圓度偏差為0.04-0.06mm,圓柱度偏差為0.08-0.12mm(通常,測量圓柱體的下半部分和上半部分之間的差值)。對于多缸發動機,圓度和圓柱度偏差基于具有大磨損的一個汽缸。
1. The inner diameter of the cylinder is excessively worn. The roundness deviation is 0.04-0.06mm, and the cylindricity deviation is 0.08-0.12mm (generally, the difference between the lower half and the upper half of the cylinder is measured). For multi cylinder engines, roundness and cylindricity deviations are based on one cylinder with large wear.
2,油量顯著增加,油壓下降,排氣管發出黑色和藍色煙霧。
2. The oil volume increases significantly, the oil pressure decreases, and the exhaust pipe emits black and blue smoke.

3,混凝土全自動攪拌車的功率大幅下降。其高馬力僅為功率的60%左右(不包括高海拔引起的功率下降),其氣缸壓力低于標準壓力的65%。
3. The power of the full-automatic concrete mixer is greatly reduced. Its high horsepower is only about 60% of the rated power (excluding the power drop caused by high altitude), and its cylinder pressure is less than 65% of the standard pressure.
4,曲軸磨損過多,曲軸磨損后曲軸的圓度和圓柱度偏差超過大使用限,或圓度和錐度限 制在0.10mm。
4. The crankshaft is worn too much, and the deviation of roundness and cylindricity of the worn crankshaft exceeds the service limit, or the roundness and taper are limited to 0.10 mm.
5,當發動機啟動或停止時,如果溫度為50^-60°C,水溫將無法平穩啟動。
5. When the engine starts or stops, if the temperature is 50 ^ - 60 ℃ ° C. The water temperature will not start smoothly.
6,發動機異?;虿僮鞑徽?。當發動機在高溫狀態下運轉時,氣缸內有噪音(活塞爆震),主軸承或連桿軸承發出嚴重的振動或敲擊聲。
6. Engine abnormal or abnormal operation. When the engine is running at high temperature, there is noise in the cylinder (piston knock), and the main bearing or connecting rod bearing makes serious vibration or knocking sound.
混凝土全自動攪拌車的售后維護工作
After sale maintenance of automatic concrete mixer
一、合理確定保護期:自拌混凝土車保護周期是指汽車保護的距離或時間。在實際應用過程中,車主應參考汽車制造商介紹的保護周期,聯系汽車自身的技術和應用前提,并對保護周期進行適當調整。一般而言,新車在優越的道路條件下使用,不需要過于頻繁地保護它們,并且制造商的常規保護期可以用作上限。如果汽車技能差,或前提不好,應適當縮短保護周期。
1、 Reasonable determination of protection period: the protection period of self mixing concrete truck refers to the distance or time of vehicle protection. In the process of practical application, the vehicle owner should refer to the protection cycle introduced by the automobile manufacturer, contact the vehicle's own technology and application premise, and adjust the protection cycle appropriately. Generally speaking, new cars are used in superior road conditions, they do not need to be protected too frequently, and the manufacturer's regular protection period can be used as the upper limit. If the vehicle skill is poor or the premise is not good, the protection cycle should be appropriately shortened.
二,測試的全 面應用:自給式攪拌機制造商的自 由檢測運動往往有利于車主的長度,車主可以應用這些測試活動進行特定的體檢,識別并消 除一些潛力實時出現問題,節約需求可能會在未來帶來高昂的維護和保護成本。
2、 Comprehensive application of testing: the free testing movement of self-contained mixer manufacturers is often conducive to the length of car owners. Car owners can use these testing activities to conduct specific physical examination, identify and eliminate some potential real-time problems, and save demand, which may bring high maintenance and protection costs in the future.
三,修 復盡可能坍塌的部件:許多自行式攪拌機的擁有者都有這種感覺,就像坍塌后汽車部件的維護不可阻擋一樣,因此車輛過早進入維修期。這種情況的原因是首先要了解修理工的裝配技巧和質量。因此,它是一種防碰撞修 復部件,它使用各種先進的技能保護設備和技術來保護自拌混凝土車免于拆卸,防止損壞汽車部件和部件,提高保護質量,從而降低總維護成本。
3、 Repair parts that collapse as much as possible: many owners of self-propelled mixers have this feeling, just like the unstoppable maintenance of automobile parts after collapse, so the vehicle enters the repair period too early. The reason for this situation is to understand the assembly skills and quality of the repairman first. Therefore, it is a kind of anti-collision repair parts, it uses a variety of advanced technical protection equipment and technology to protect the self mixing concrete truck from disassembly, prevent damage to automobile parts and components, improve the quality of protection, so as to reduce the total maintenance cost.
混凝土全自動攪拌車發動機大修問題和售后維護工作介紹就是這樣了,希望對你有幫助。
