Now the market demand of self feeding mixer is very large, many people who buy mixer are not very clear about the maintenance of newly purchased mixer. The maintenance of self feeding mixer is still very important. Careful maintenance can effectively extend the service life of mixer. The engine plays an important role in the self feeding mixer. The power source of the mixer depends on the engine, so we focus on the maintenance of the mixer engine.

首先是磨合，新車都是有磨合期的，磨合是延長自上料攪拌車使用壽命的基礎(chǔ)，一定要按說明書上的規(guī)定進(jìn)行磨合。油凈、水凈、氣凈和機(jī)體凈。柴油是攪拌車發(fā)動機(jī)的主要燃料，如果柴油不純凈，會使精密的配合機(jī)體磨合，配合間隙增大，造成漏油，滴油，供油壓力降低，間隙變大，甚至造成油路堵塞，抱軸燒瓦等嚴(yán)重故障。

The first is running in. All new cars have a running in period. Running in is the basis for extending the service life of self loading mixer. It must be run in according to the instructions. Oil purification, water purification, gas purification and body purification. Diesel is the main fuel of the mixer engine. If the diesel is not pure, it will make the precise matching body run in, increase the matching clearance, cause oil leakage, oil dripping, reduce the fuel supply pressure, increase the clearance, and even cause serious faults such as oil blockage, axle burning and so on.

若空氣中含有大量塵土，將會加速缸套、活塞和活塞環(huán)的磨損。若冷卻水不純凈，會使冷卻系水垢堵塞后，妨礙發(fā)動機(jī)散熱，潤滑條件也差，機(jī)體磨損嚴(yán)重。若機(jī)體外表不干凈，會使表面受到腐蝕，縮短使用壽命。柴油和空氣中供應(yīng)不及時或中斷，就會出現(xiàn)啟動困難，燃燒不良，功率下降，發(fā)動機(jī)不能正常運(yùn)轉(zhuǎn)等現(xiàn)象。若冷卻水供應(yīng)不足就會使機(jī)溫過高，功率下降磨損加劇，降低使用壽命。

If there is a lot of dust in the air, it will accelerate the wear of cylinder liner, piston and piston ring. If the cooling water is not pure, it will block the scale of the cooling system, hinder the engine heat dissipation, poor lubrication conditions and serious wear of the engine body. If the body surface is not clean, the surface will be corroded and the service life will be shortened. If the supply of diesel and air is not timely or interrupted, it will be difficult to start, poor combustion, power decline, engine can not run normally and so on. If the cooling water supply is insufficient, the temperature of the machine will be too high, the power will be reduced, the wear will be intensified, and the service life will be reduced.

經(jīng)常檢查緊固部位

Check the fastening parts frequently

水泥自動攪拌車。因柴油機(jī)使用的過程中受震動沖擊和負(fù)荷不均勻等影響，螺栓，螺母容易松動。還有各部位的調(diào)整螺栓都要檢查，以免造成因松動而損壞機(jī)體的事故。

Self feeding mixer. Due to the impact of vibration and uneven load during the use of diesel engine, bolts and nuts are easy to loosen. There are all parts of the adjustment bolts to check, so as not to cause loose and damage to the body accident.

檢查調(diào)整

Check and adjust

柴油機(jī)的氣門間隙、配氣相位、共有提前角、噴油壓力以及點(diǎn)火正時等都應(yīng)及時檢查并調(diào)整，以保證發(fā)動機(jī)經(jīng)常處于良好的技術(shù)狀態(tài)，方能節(jié)省燃油，延長使用壽命。

The valve clearance, valve timing, common advance angle, injection pressure and ignition timing of diesel engine should be checked and adjusted in time to ensure that the engine is always in good technical condition, so as to save fuel and prolong service life.

正確使用發(fā)動機(jī)

Correct use of engine

自上料攪拌車行駛前，應(yīng)使各瓦軸等潤滑部位得到潤滑。啟動后應(yīng)待水溫達(dá)到40℃-50℃時再投入到作業(yè)，嚴(yán)禁長時間超負(fù)荷或低速作業(yè)。停機(jī)前，應(yīng)先卸掉負(fù)荷降低轉(zhuǎn)速。

Before the feeding mixer runs, the bearing shaft and other lubrication parts should be lubricated. After start-up, it should be put into operation when the water temperature reaches 40 ℃ - 50 ℃. Long time overload or low speed operation is strictly prohibited. Before shutdown, the load should be removed to reduce the speed.
