Some customers report that their tank cars react slowly. Generally, during cement transportation, when they are delivered and unloaded at the workplace, the unloading speed of some mixing tanks is not very fast. What are the reasons? The following is a small series from the charging mixing tank truck manufacturer to analyze the reasons for this.

大家對(duì)罐車(chē)的不了解其中原因，不是小型攪拌站車(chē)罐體轉(zhuǎn)速不快，而是這種速度不快的攪拌車(chē)只是小型攪拌車(chē)中的一種，它關(guān)健的部位在于液壓泵和液壓馬達(dá)不一樣，這種均速的小型攪拌車(chē)液壓泵叫做定量齒輪泵，它的工作速度不是很快，就是加油門(mén)也提高不了多少，同時(shí)還不能過(guò)快的長(zhǎng)時(shí)間的加油門(mén)，防止燒壞齒輪油泵。

The reason why people don't know about tank cars is not that the tank body of small-scale mixing plant is not rotating fast, but that this slow-moving mixing car is only one of small-scale mixing cars. Its key part is that the hydraulic pump is different from the hydraulic motor. This uniform speed hydraulic pump of small-scale mixing car is called quantitative gear pump, and its working speed is not very fast, Even the oil filling valve can't be improved much. At the same time, the oil filling valve can't be too fast for a long time to prevent burning out the gear oil pump.

另外還有一種就是柱塞式變量泵，這種攪拌車(chē)泵的明顯的地方就是攪拌罐在卸料時(shí)，轉(zhuǎn)速快，出料快，正常在運(yùn)輸過(guò)程中，可以均速轉(zhuǎn)動(dòng)。柱塞式變量泵和定量齒輪泵在外形上面也是有區(qū)別的，柱塞式變量泵的外形更大些，結(jié)構(gòu)更復(fù)雜些。

In addition, there is a plunger variable displacement pump. The obvious place of this mixer pump is that the mixing tank can rotate at a uniform speed during unloading. Plunger variable displacement pump and quantitative gear pump are also different in shape. The shape of plunger variable displacement pump is larger and the structure is more complex.

攪拌罐車(chē)裝料時(shí)應(yīng)注意不要將粉罐裝滿(mǎn)，應(yīng)預(yù)留部分空間使粉粒擴(kuò)容；還應(yīng)避免將雜物混入罐內(nèi)，使排料管堵塞，影響排料速度和剩余率。

When loading the mixing tank truck, pay attention not to fill the powder tank, and reserve some space to expand the capacity of powder particles; It shall also avoid mixing sundries into the tank to block the discharge pipe and affect the discharge speed and residual rate.

自上料攪拌罐車(chē)進(jìn)行卸料操作時(shí)，如空壓機(jī)有異常聲響，應(yīng)踩下離合器踏板，關(guān)閉發(fā)動(dòng)機(jī)，關(guān)閉取力器電磁閥開(kāi)關(guān)，直故障排除，才能工作；還應(yīng)特別留意壓力表變化，操作人員不能離開(kāi)現(xiàn)場(chǎng)，避免壓力過(guò)高的現(xiàn)象發(fā)生。日常使用中應(yīng)保持罐內(nèi)干燥，避免粉料結(jié)塊；汽車(chē)維修時(shí)，應(yīng)防止零件摔碰，避免敲擊，以防止零件損傷、變形、磕碰、劃痕等，零件裝復(fù)時(shí)必 須注意清潔。空壓機(jī)工作時(shí)，空壓機(jī)側(cè)應(yīng)避免站人。提速時(shí)，加油門(mén)不要過(guò)猛，用力要均勻。吸料口與底部距離可調(diào)整，一般在30～50mm。切記不能用外接氣源口排氣。

If the air compressor has abnormal sound during unloading operation from the loading mixing tank truck, step on the clutch pedal, turn off the engine and turn off the solenoid valve switch of the power take-off until the fault is eliminated; Special attention shall also be paid to the change of pressure gauge. Operators shall not leave the site to avoid excessive pressure. Keep the tank dry during daily use to avoid powder caking; During vehicle maintenance, parts shall be prevented from falling and knocking, so as to prevent parts from damage, deformation, bump, scratch, etc. parts must be cleaned during reassembly. When the air compressor is working, avoid standing on the air compressor side. When accelerating, the fuel door should not be too fierce and the force should be uniform. The distance between the suction port and the bottom can be adjusted, generally 30 ~ 50mm. Remember not to exhaust with an external air source.
