如何預(yù)防小型混凝土攪拌車汽缸破裂？
小型混凝土攪拌車汽缸是與活塞構(gòu)成工作容積的部件，氣缸的作用是將壓縮空氣的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)機(jī)構(gòu)作直線往復(fù)運(yùn)動(dòng)、擺動(dòng)和旋轉(zhuǎn)運(yùn)動(dòng)。那么，如何預(yù)防小型混凝土攪拌車汽缸破裂呢？下面為大家介紹下：
The cylinder of a small concrete mixer truck is a component which forms the working volume with the piston. The function of the cylinder is to convert the pressure energy of compressed air into mechanical energy, and the driving mechanism performs linear reciprocating motion, swing and rotation motion. So, how to prevent the cylinder from cracking? Let's introduce the following:
導(dǎo)致小型混凝土攪拌車氣缸破裂的因素很多，要預(yù)防氣缸破裂，應(yīng)該做到：發(fā)動(dòng)機(jī)溫度過高時(shí)，必須等發(fā)動(dòng)機(jī)溫度降低后，再加水發(fā)動(dòng)；不得先啟動(dòng)發(fā)動(dòng)機(jī)，后加冷卻水，以免使氣缸崩裂；在嚴(yán)寒條件下車，須放凈冷卻水，啟動(dòng)車時(shí)加熱水啟動(dòng)；冬季停車若時(shí)間較長，又不能放水時(shí)，可間歇發(fā)動(dòng)車輛，保持發(fā)動(dòng)機(jī)有一定溫度而不致于結(jié)冰，不得用噴燈或明火直接烤車，同時(shí)使用的冷卻水要潔凈。
There are many factors leading to the cylinder rupture of small concrete mixer truck. To prevent cylinder rupture, we should do: when the engine temperature is too high, we must wait for the engine temperature to reduce before adding water to start; do not start the engine first and then add cooling water to avoid cylinder cracking; when getting off the vehicle in severe cold conditions, it is necessary to drain the cooling water and start the truck with heated water; if the time for parking in winter is too long When it is too long and water cannot be drained, the vehicle can be started intermittently to keep the engine at a certain temperature without freezing. It is not allowed to bake the car directly with blowtorch or open fire. At the same time, the cooling water used should be clean.
小型混凝土攪拌車如果氣缸套出現(xiàn)破損，發(fā)動(dòng)機(jī)在進(jìn)氣行程時(shí)會(huì)吸入冷卻液，而在壓縮行程和做功行程時(shí)高壓氣體又會(huì)從破損處進(jìn)入冷卻水道。無論出現(xiàn)哪一種情況，都將妨礙可燃混合氣的形成和燃燒，甚使發(fā)動(dòng)機(jī)無法正常工作，將嚴(yán)重影響發(fā)動(dòng)機(jī)的使用壽命。
If the cylinder liner of a small concrete mixer is damaged, the engine will inhale coolant during the intake stroke, and the high-pressure gas will enter the cooling channel from the damaged part during the compression stroke and power stroke. No matter what kind of situation appears, it will hinder the formation and combustion of combustible mixture, and even make the engine unable to work normally, which will seriously affect the service life of the engine.
