誤區(qū)1：機油寧多不可少

Mistake 1: more oil is necessary

曲軸箱內的機油不可多加，也不能少加，機油過多會增加曲柄連桿機構的滾動阻力，還會使飛濺到氣缸壁上的機油增多。機油過多會導致燃燒室積碳增加，自上料混凝土攪拌罐車發(fā)動機功率下降，從而會影響到排放。司機在查看或增加機油的時候，應按照機油標尺上面的刻度增加，機油液位不能超過標尺刻度上限，低不能低于標尺刻度下線，自上料混凝土攪拌罐車機油液位一般增加到兩刻度偏上的方位比較適宜。

The engine oil in the crankcase can not be added more or less. Too much oil will increase the rolling resistance of the crank connecting rod mechanism and increase the oil splashing on the cylinder wall. Too much oil will lead to the increase of carbon deposition in the combustion chamber, and the engine power of concrete mixer will decrease, which will affect the emissions. When checking or adding engine oil, the driver should increase according to the scale on the oil scale. The oil level should not exceed the upper limit of the scale, and the low level should not be lower than the lower limit of the scale. Generally, it is more appropriate to increase the oil level of the concrete mixer truck to the position above the center of the two scales.

誤區(qū)2：胎壓寧高不能低

Misunderstanding 2: tire pressure should be higher than low

有些司機喜歡把輪胎氣壓充得很高，認為這樣既能超載又可節(jié)油，這種做法是不正確的。自上料混凝土攪拌罐車輪胎氣壓過高會使輪胎接地上減小，胎面磨損加重，下降了剎車時的制動效果，這會影響到自上料混凝土攪拌罐車行車。輪胎氣壓過低也欠好，氣壓過低除了會影響自上料混凝土攪拌罐車行車和制動效果以外，還會加速胎肩的磨損，以及增加自上料混凝土攪拌罐車的燃油耗費。司機在運用氣泵自行充氣的時分，應當按照廠家規(guī)矩的氣壓進行充氣，輪胎氣壓標簽一般位于車身或是油箱蓋上面。
 

Some drivers like to inflate their tires at a high pressure, believing that this can not only overload but also save fuel, which is not correct. If the tire pressure of concrete mixer is too high, the tire ground will be reduced, the tread wear will be aggravated, and the braking effect will be reduced when braking, which will affect the driving of concrete mixer. Too low tire pressure is not good, too low pressure will not only affect the driving and braking effect of concrete mixer, but also accelerate the wear of tire shoulder and increase the fuel consumption of concrete mixer. When using the air pump to inflate, the driver should inflate according to the manufacturer's regulations. The tire pressure label is usually located on the body or the fuel tank cover.

誤區(qū)3：車輪螺絲寧緊勿松

Mistake 3: wheel screws should be tight rather than loose

自上料混凝土攪拌罐車各部位的螺栓，根據(jù)直徑、螺距及用途的不同，其緊固力矩均有相應規(guī)矩，達不到規(guī)矩的力矩螺栓會松動，超過緊固的力矩螺栓會被拉長。在對各部件緊固之前，需求先把握各螺栓的緊固力矩，例如車輪螺栓，一般情況家用自上料混凝土攪拌罐車輪胎螺栓的緊固力矩在100-130N·m之間。

According to the diameter, pitch and use, the tightening torque of the bolts in each part of the concrete mixer has corresponding rules. If the torque is not up to the standard, the bolt will be loose, and the bolt beyond the tightening torque will be elongated. Before fastening all parts, it is necessary to grasp the tightening torque of each bolt, such as wheel bolt. Generally, the tightening torque of tire bolt of domestic concrete mixer truck is between 100-130n · M.

誤區(qū)4：附件皮帶寧緊勿松

Error 4: the accessory belt should be tight rather than loose

有些司機認為前進附件皮帶的漲緊度，可以前進壓縮機的制冷效果，以及發(fā)電機的發(fā)電量，因此便一個勁地前進皮帶的緊度，殊不知這種做法是差錯的。附件皮帶應當堅持恰當?shù)臐q緊度，由于皮帶過緊會使軸承負荷過大，會縮短部件的運用壽命，還會導致皮帶呈現(xiàn)開裂，會影響到自上料混凝土攪拌罐車的正常運用。

Some drivers think that the belt tension of the forward accessory can advance the refrigeration effect of the compressor and the power generation capacity of the generator, so they keep on pushing forward the belt tightness, but they don't know that this practice is wrong. The belt of accessories should adhere to the appropriate degree of tension. Because the belt is too tight, the bearing load will be too large, the service life of the parts will be shortened, and the belt will crack, which will affect the normal operation of the concrete mixer truck.
