如何保養(yǎng)混凝土自上料攪拌車的燃油系統(tǒng)？
我們都知道，混凝土自上料攪拌車的發(fā)動(dòng)機(jī)能夠正常運(yùn)轉(zhuǎn)，機(jī)械穩(wěn)定的作業(yè)，這些都離不開燃油系統(tǒng)為其提供動(dòng)力。我們?cè)谑褂没炷翑嚢柢嚨臅r(shí)候也會(huì)遇到發(fā)動(dòng)機(jī)無法啟動(dòng)或啟動(dòng)無力的現(xiàn)象，這一般都是因?yàn)榛炷翑嚢柢嚨娜加拖到y(tǒng)出現(xiàn)了故障，所以，我們?cè)谄綍r(shí)使用的時(shí)候就要做好燃油系統(tǒng)的日常保養(yǎng)，具體內(nèi)容請(qǐng)看下文。
As we all know, the engine of concrete self loading mixer can operate normally and operate mechanically stably, which cannot be separated from the power provided by the fuel system. When we use the concrete mixer, we will also encounter the phenomenon that the engine can not start or the start is weak. This is generally due to the failure of the fuel system of the concrete mixer. Therefore, we need to do a good job in the daily maintenance of the fuel system when we use it. Please see the following for the specific content.
1、及時(shí)加注燃油
1. Fill the fuel in time
混凝土攪拌車作業(yè)的過程中，操作人員要隨時(shí)關(guān)注燃油量，當(dāng)燃油表顯示的燃油量接近“0”位時(shí)，要及時(shí)加注燃油。切忌等燃油用盡之后才添加，這樣做的后果不僅僅是造成柴油機(jī)無油后熄火，重要的是會(huì)導(dǎo)致空氣進(jìn)入燃油系統(tǒng)，一旦燃油系統(tǒng)中進(jìn)入了空氣，不僅浪費(fèi)了燃油，而且排出去比較麻煩。
In the process of concrete mixer operation, the operator should pay attention to the fuel quantity at any time. When the fuel quantity shown on the fuel meter is close to the "0" position, the fuel should be filled in time. Do not add fuel until it is exhausted. This will not only cause the diesel engine to stop when there is no fuel, but also cause air to enter the fuel system. Once air enters the fuel system, it will not only waste fuel, but also cause trouble in discharging.
2、注意避免燃油系統(tǒng)堵塞
2. Pay attention to avoid fuel system blockage
我們都知道，有時(shí)候混凝土攪拌車的工作環(huán)境比較特殊，這樣就很容易導(dǎo)致混凝土攪拌車燃油系統(tǒng)堵塞，一旦燃油系統(tǒng)堵塞，就會(huì)影響機(jī)器的正常運(yùn)轉(zhuǎn)，所以要及時(shí)檢查確保燃油管道的通暢。
As we all know, sometimes the working environment of the concrete mixer is special, which can easily lead to the blockage of the fuel system of the concrete mixer. Once the fuel system is blocked, it will affect the normal operation of the machine, so it is necessary to check in time to ensure the smoothness of the fuel pipe.
3、注意檢查燃油系統(tǒng)密封性
3. Pay attention to check the tightness of the fuel system
混凝土攪拌車作業(yè)的時(shí)候，如果發(fā)現(xiàn)排氣管冒黑煙，或是發(fā)動(dòng)機(jī)出現(xiàn)啟動(dòng)困難的狀況，有可能是因?yàn)槁?，所以要注意檢查燃油系統(tǒng)的密封性。
When the concrete mixer truck is working, if it is found that the exhaust pipe is emitting black smoke, or the engine is difficult to start, it may be due to air leakage, so pay attention to check the tightness of the fuel system.
4、保持燃油的清潔
4. Keep the fuel clean
混凝土攪拌車燃油系統(tǒng)的故障有大約50%是因?yàn)槿加筒粷嵥斐?，?duì)于汽油機(jī)而言，絕大多數(shù)是因?yàn)槿加椭谢烊胨?，汽油中的水分還會(huì)腐蝕和破壞燃油供油系統(tǒng)元件。
About 50% of the faults of the fuel system of the concrete mixer truck are caused by the unclean fuel. For the gasoline engine, most of them are caused by the water in the fuel. The water in the gasoline will also corrode and damage the components of the fuel supply system.
5、燃油選擇很關(guān)鍵
5. Fuel selection is key
建議選擇適合混凝土攪拌車的高品質(zhì)燃油，質(zhì)量較差的燃油過濾不良，油泥、雜質(zhì)、水分，長期積累，沉淀下來，容易堵塞油泵濾網(wǎng)，油管及噴油嘴。
It is suggested that high quality fuel suitable for concrete mixer should be selected. The poor quality fuel has poor filtration, sludge, impurities, moisture, long-term accumulation and precipitation, which is easy to block the filter screen, oil pipe and nozzle of oil pump.
混凝土攪拌車是用來運(yùn)送建筑用混凝土的專用卡車；由于它的外形，也常被稱為田螺車，這類卡車上都裝置圓筒型的攪拌筒以運(yùn)載混合后的混凝土。在運(yùn)輸過程中會(huì)始終保持?jǐn)嚢柰厕D(zhuǎn)動(dòng)，以保障所運(yùn)載的混凝土不會(huì)凝固，運(yùn)送完混凝土后，通常都會(huì)用水沖洗攪拌筒內(nèi)部，防止硬化的混凝土占用空間。
Concrete mixer truck is a special truck used to transport construction concrete; Because of its shape, it is often called Tianluo truck. This kind of truck is equipped with cylindrical mixing drum to carry the mixed concrete. During transportation, the mixing drum will always rotate to ensure that the concrete will not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from occupying space.
