After investigation, it is found that many users of mixer truck report that the unloading speed of mixer truck is relatively slow. Why?

　　其實(shí)一般卸料慢的大部分都是小型攪拌車，那只是因?yàn)樗帕啃〔判读下龁幔慨?dāng)然不是，攪拌車卸料慢跟液壓泵和液壓馬達(dá)有關(guān)，一般小型攪拌車的液壓馬達(dá)都是定量齒輪泵，它的工作速度不怎么快，就是加油門也不會(huì)有明顯改善，而且還不能長(zhǎng)時(shí)間的加大油門會(huì)燒壞齒輪油泵。還有一種攪拌車的液壓泵是柱塞式變量泵，這種攪拌車在運(yùn)輸過(guò)程中一般速度較慢，但在卸料時(shí)，轉(zhuǎn)速快，出料快。

　　In fact, most of the slow unloading is small mixer. Is it only because of its small volume? Of course not. The slow unloading of mixer truck is related to the hydraulic pump and hydraulic motor. Generally, the hydraulic motor of small mixer truck is fixed displacement gear pump. Its working speed is not very fast, even the filling door will not be significantly improved. Moreover, if the accelerator is increased for a long time, the gear oil pump will be burnt out. The hydraulic pump of another kind of mixer is plunger type variable displacement pump. The speed of this kind of mixer is generally slow in the process of transportation, but when discharging, the speed is fast and the discharge is fast.

　　定量泵和柱塞式變量泵在外形上也是有區(qū)別的，柱塞式變量泵外形尺寸比定量泵要大一些，結(jié)構(gòu)上也更為復(fù)雜，對(duì)于攪拌車卸料一定要注意一些問(wèn)題。

　　There are also differences between the fixed displacement pump and the plunger variable pump in appearance. The external dimension of the plunger type variable displacement pump is larger than that of the fixed displacement pump, and the structure is more complex. Some problems must be paid attention to when the mixer truck is discharging.
               

　　混凝土攪拌車在裝料時(shí)盡量不要裝太滿，要預(yù)留一些空間讓粉粒擴(kuò)容，要注意在裝料時(shí)避免一些雜物混入攪拌罐內(nèi)，因?yàn)檫@樣會(huì)使卸料管堵塞，影響卸料速度和剩余率。

　　First of all, the concrete mixer truck should not be too full when loading. Some space should be reserved for powder expansion. Attention should be paid to avoid some sundries mixing into the mixing tank during loading, because this will block the discharge pipe and affect the unloading speed and residual rate.

　　中科聚峰混凝土攪拌車在卸料時(shí)，如果空壓機(jī)有異常聲響，應(yīng)踩下離合器，關(guān)閉發(fā)動(dòng)機(jī)，關(guān)閉取力器，直到故障排除才能繼續(xù)卸料；還有就是在卸料時(shí)，一定要注意壓力表的變化，整個(gè)卸料過(guò)程中作業(yè)人員都不能離開現(xiàn)場(chǎng)，避免壓力過(guò)高現(xiàn)象的發(fā)生。在空壓機(jī)工作時(shí)，在空壓機(jī)的側(cè)面應(yīng)避免站人。提速時(shí)加油門要均勻。在平時(shí)攪拌車不用時(shí)一定要保持罐內(nèi)的干燥清潔；在車輛維修時(shí)，一定要注意防止零件的碰撞，避免敲擊，以免對(duì)零件造成損壞、變形、磕碰、劃痕等。吸料口和底部距離可以調(diào)整，一般在30-50mm。切記不能用外接氣源口排氣。

　　When unloading, if the air compressor has abnormal sound, the clutch should be stepped down, the engine should be shut down, the power take-off should be turned off, and the unloading can not be continued until the fault is eliminated. In addition, the change of the pressure gauge must be paid attention to during the unloading process. The operators can not leave the site during the whole unloading process to avoid the occurrence of high pressure. In the air compressor work, in the side of the air compressor should avoid standing. The fuel door should be even when speeding up. When the mixer truck is not in use, it is necessary to keep the tank dry and clean; during vehicle maintenance, attention must be paid to prevent parts from collision and knocking, so as to avoid damage, deformation, bump and scratch of parts. The distance between the suction port and the bottom can be adjusted, generally in 30-50 mm. Remember not to exhaust with external gas source.

　　當(dāng)空壓機(jī)加壓過(guò)程中因其他原因而停止空壓機(jī)工作時(shí)，應(yīng)關(guān)閉前后倉(cāng)的近期球閥，然后把外接氣源打開，過(guò)一會(huì)再關(guān)閉外接氣源，打開前后倉(cāng)的進(jìn)氣球閥。

　　When the air compressor stops working due to other reasons during the pressurization process of the air compressor, close the short-term ball valves of the front and rear chambers, and then turn on the external air source. After a while, close the external air source and open the inlet balloon valve of the front and rear chambers.

　　在卸料后沖洗車輛時(shí)，上下扶梯要抓緊扶手，身體嚴(yán)禁接觸轉(zhuǎn)動(dòng)部位。沖洗完車輛后要將水箱閥門關(guān)閉，固定好卸料槽及水管。

　　When washing the vehicle after unloading, hold the handrail tightly when going up and down the escalator. Do not touch the rotating parts. After washing the vehicle, close the water tank valve and fix the discharge tank and water pipe.

　　每天下班后要對(duì)車輛做整體檢查，發(fā)現(xiàn)故障要及時(shí)維修。

　　After work every day to do an overall inspection of the vehicle, found fault to repair in time.

　　對(duì)于攪拌車卸料的注意事項(xiàng)一定要牢記，這樣才能延長(zhǎng)攪拌車的使用壽命，是可以帶給我們更多收益的!如您還有其他問(wèn)題歡迎咨詢中科聚峰混凝土攪拌車網(wǎng)站。

　　For the mixer unloading matters must be kept in mind, so as to extend the service life of the mixer truck, which can bring us more benefits! If you have other questions, please consult the website of Zhongke Jufeng concrete mixer.
