在某些工作情况下,由于水泥自动搅拌车运输距离短,为了在短距离内将搅拌车动臂快速的提升到位,又要整机行驶速度不快,很多机手都会让搅拌车的刹车盘处于憋闷的状态,事实上这会给搅拌车带来很多的隐患,下面具体看下吧。
In some working cases, due to the short transportation distance of the automatic cement mixer, in order to quickly lift the boom of the mixer in place in a short distance, and the running speed of the whole machine is not fast, many machine operators will keep the brake disc of the mixer in a suffocating state. In fact, this will bring a lot of potential safety hazards to the mixer. Let's take a look at the details below.
这样的憋闷会让搅拌车的刹车盘温度升高,刹车盘温度通过传导和辐射加热刹车油,使刹车油产生汽化,导致刹车系统的油路被气体隔断,压力不能及时进行传递,搅拌车的夹钳活塞由于气阻“背压”不回位而抱死,加力缸由于气阻“背压”产生喷油现象,越热汽化越严重,“背压”越大摩擦温度越高,喷油现象越严重,刹车油越浪费。
Such suffocation will raise the temperature of the brake disc of the mixer truck. The brake disc temperature heats the brake oil through conduction and radiation, causing the brake oil to vaporize, resulting in the oil circuit of the brake system being cut off by gas, and the pressure cannot be transmitted in time. The clamp piston of the mixer truck is locked due to the "back pressure" of the air resistance, and the afterburner cylinder produces oil injection due to the "back pressure" of the air resistance. The hotter the vaporization is, the more serious the "back pressure" is, and the higher the friction temperature is, The more serious the fuel injection, the more wasted the brake oil.
缺油时,不及时对搅拌车刹车系统进行加油和排气导致空气进入刹车油路,产生气阻现象,造成刹车失灵,形成隐患。因此,对搅拌车的行车制动可靠性能、行车紧急制动以及停车制动性能也提出了更高的要求。
When there is a lack of oil, failure to refuel and exhaust the brake system of the mixer in time leads to air entering the brake oil circuit, resulting in air resistance, brake failure and potential safety hazards. Therefore, higher requirements are put forward for the reliability of service braking, emergency braking and parking braking performance of the mixer truck.
此外如果搅拌车的驱动发生了无力的现象就需要先检查变速表是否在一档的位置和是否出现了降压的情况。而造成驱动无力的原因就是因为在一档的时候活塞环摩擦增加,磨损加大,这就会导致漏油量增加,就会导致驱动无力。
In addition, if the driving of the mixer truck is weak, it is necessary to check whether the transmission meter is in the first gear position and whether there is pressure reduction. The reason for driving weakness is that the piston ring friction and wear increase in the first gear, which will lead to an increase in oil leakage, which will lead to driving weakness.
另外还有种原因就可能是因为
水泥自动搅拌车的o型密封圈受损,造成了压力油的泄漏。如果排查出是因为上述原因导致的驱动无力,可以先把变速箱拿出,然后更换里面的活塞环和密封圈。
Another reason may be that the O-ring of the automatic cement mixer is damaged, resulting in the leakage of pressure oil. If it is found that the drive is weak due to the above reasons, you can take out the gearbox first, and then replace the piston ring and sealing ring inside.
