在某些工作情況下，由于水泥自動(dòng)攪拌車運(yùn)輸距離短，為了在短距離內(nèi)將攪拌車動(dòng)臂快速的提升到位，又要整機(jī)行駛速度不快，很多機(jī)手都會(huì)讓攪拌車的剎車盤處于憋悶的狀態(tài)，事實(shí)上這會(huì)給攪拌車帶來很多的隱患，下面具體看下吧。

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.

這樣的憋悶會(huì)讓攪拌車的剎車盤溫度升高，剎車盤溫度通過傳導(dǎo)和輻射加熱剎車油，使剎車油產(chǎn)生汽化，導(dǎo)致剎車系統(tǒng)的油路被氣體隔斷，壓力不能及時(shí)進(jìn)行傳遞，攪拌車的夾鉗活塞由于氣阻“背壓”不回位而抱死，加力缸由于氣阻“背壓”產(chǎn)生噴油現(xiàn)象，越熱汽化越嚴(yán)重，“背壓”越大摩擦溫度越高，噴油現(xiàn)象越嚴(yán)重，剎車油越浪費(fèi)。

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.

缺油時(shí)，不及時(shí)對攪拌車剎車系統(tǒng)進(jìn)行加油和排氣導(dǎo)致空氣進(jìn)入剎車油路，產(chǎn)生氣阻現(xiàn)象，造成剎車失靈，形成隱患。因此，對攪拌車的行車制動(dòng)可靠性能、行車緊急制動(dòng)以及停車制動(dòng)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.

此外如果攪拌車的驅(qū)動(dòng)發(fā)生了無力的現(xiàn)象就需要先檢查變速表是否在一檔的位置和是否出現(xiàn)了降壓的情況。而造成驅(qū)動(dòng)無力的原因就是因?yàn)樵谝粰n的時(shí)候活塞環(huán)摩擦增加，磨損加大，這就會(huì)導(dǎo)致漏油量增加，就會(huì)導(dǎo)致驅(qū)動(dòng)無力。

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.

另外還有種原因就可能是因?yàn)?a href="http://f3328.cn">水泥自動(dòng)攪拌車的o型密封圈受損，造成了壓力油的泄漏。如果排查出是因?yàn)樯鲜鲈驅(qū)е碌尿?qū)動(dòng)無力，可以先把變速箱拿出，然后更換里面的活塞環(huán)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.
