混凝土攪拌車，為了提高水泥的運(yùn)送，避免袋裝水泥形成的資源浪費(fèi)，現(xiàn)在很多的水泥都選用散裝小型混凝土攪拌車運(yùn)送，因小型混凝土攪拌車選用氣力輸送卸料，卸料速度和卸料剩下率是查核水泥罐車卸料功率的重要目標(biāo)。混凝土攪拌車，怎么確保車罐內(nèi)水泥盡量卸完、卸盡，選用正確的辦法非常重要。因卸料過(guò)程中罐內(nèi)水泥無(wú)法肉眼直觀看到，有必要憑借一些辦法區(qū)分水泥卸料狀況，混凝土攪拌車介紹幾種簡(jiǎn)易判別水泥是否卸完的辦法：
Concrete mixer, in order to improve the transportation of cement, avoid the waste of resources formed by bagged cement, now a lot of cement are transported by bulk small concrete mixer, because the small concrete mixer uses pneumatic conveying to discharge, discharge speed and discharge remaining rate are the important objectives of checking the discharge power of cement tank truck. Concrete mixer, how to ensure that the car tank of cement as far as possible to unload, unload, select the correct method is very important. Because the cement in the tank can not be seen directly by naked eyes during the discharging process, it is necessary to distinguish the discharging condition of cement by some methods
壓力表查看法，小型混凝土攪拌車在卸料時(shí)，罐內(nèi)空氣壓力為1.8～2.4公斤/平方厘米，小型混凝土攪拌車卸料快結(jié)束時(shí)，氣壓快速下降，假如壓力表降到0～0.2公斤/平方厘米之間，則證明罐內(nèi)水泥根本卸完。
According to the pressure gauge, the air pressure in the tank is 1.8-2.4 kg / cm2 when the small concrete mixer is discharging. When the small concrete mixer is discharging, the air pressure drops rapidly. If the pressure gauge drops to 0-0.2 kg / cm2, it proves that the cement in the tank is completely discharged.
小型混凝土攪拌車卸料時(shí)刻判別法，正常水泥罐卸料速度一般為每分種1～1.2噸，假如水泥裝載分量為32噸，則一般需求半小時(shí)左右卸完，所以能夠依據(jù)卸料噸位核算卸料時(shí)刻，這樣前25分鐘操作人員比較輕松，沒有必要長(zhǎng)時(shí)刻緊盯壓力表或經(jīng)過(guò)其它辦法查看是否卸完。
According to the method of judging the discharging time of small concrete mixer, the discharging speed of normal cement tank is generally 1-1.2 tons per minute. If the loading capacity of cement is 32 tons, it usually takes about half an hour to finish discharging. Therefore, the discharging time can be calculated according to the discharging tonnage, which makes it easier for the operators in the first 25 minutes, There is no need to keep a close eye on the pressure gauge for a long time or go through other ways to check whether it has been unloaded.
空壓機(jī)聲響區(qū)分法，正常卸料時(shí)空壓機(jī)負(fù)載大，空壓機(jī)作業(yè)時(shí)宣布的聲響比較煩悶，罐體卸料結(jié)束時(shí)，空壓機(jī)負(fù)載變小，作業(yè)聲響變得洪亮?；炷翑嚢柢?/div>
According to the method of distinguishing the sound of air compressor, the load of air compressor is large during normal discharge, and the sound announced during the operation of air compressor is boring. At the end of tank discharge, the load of air compressor becomes smaller and the operation sound becomes loud. Concrete mixer truck
擊打罐體法，水泥卸料過(guò)程中，能夠用手擊打小型混凝土攪拌車罐體，假如聲響沒有回音，則證明罐體內(nèi)水泥余料較多，還要卸一段時(shí)刻；假如罐體有回音，證明罐體內(nèi)水泥快卸完了。
In the process of cement unloading, the tank of small concrete mixer can be hit by hand. If the sound has no echo, it proves that there is more cement in the tank, and it needs to be unloaded for a period of time; If the tank has an echo, it proves that the cement in the tank is almost discharged.
卸料軟管觀察法，正常卸料時(shí)，卸料軟管受流化水泥沖擊，軟管不斷顫動(dòng)，假如軟管不再顫動(dòng)，也可證明罐內(nèi)水泥根本卸完。
According to the observation method of discharge hose, during normal discharge, the discharge hose is impacted by fluidizing cement, and the hose vibrates continuously. If the hose no longer vibrates, it can also prove that the cement in the tank is completely discharged.
水泥接納塔頂揚(yáng)灰區(qū)分法，小型混凝土攪拌車正常卸料時(shí)，水泥耗費(fèi)的氣量相對(duì)較少，“料多氣少”，接納塔頂揚(yáng)灰較少，卸料后期“料少氣多”，接納塔頂揚(yáng)灰增多。
According to the division method of cement receiving tower top ash, when the small concrete mixer truck is discharging normally, the air consumption of cement is relatively less, "more material and less gas", less receiving tower top ash, and "less material and more gas" at the later stage of discharging, more receiving tower top ash.
混凝土攪拌車，以上方法可簡(jiǎn)略的區(qū)分小型混凝土攪拌車水泥是否卸完，各類水泥罐車因?yàn)榻Y(jié)構(gòu)不同、選用空壓機(jī)不同、水泥接納塔的高度不同，以及所裝水泥的比重不同，在卸料速度和剩下率也會(huì)有所不同，司機(jī)可經(jīng)過(guò)記載實(shí)踐操作辦法和卸料時(shí)刻，不斷總結(jié)經(jīng)驗(yàn)，取得的操作辦法，到達(dá)的卸料功率。
For concrete mixer truck, the above methods can briefly distinguish whether the cement of small concrete mixer truck has been unloaded or not. Due to different structures, different air compressors, different heights of cement receiving tower and different proportion of cement, the unloading speed and remaining rate of various cement tank trucks are also different. The driver can record the practical operation method and unloading time, Constantly sum up experience, to achieve the best operation method, to achieve the highest discharge power.
