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

　　其实一般卸料慢的大部分都是小型搅拌车，那只是因为它放量小才卸料慢吗？当然不是，搅拌车卸料慢跟液压泵和液压马达有关，一般小型搅拌车的液压马达都是定量齿轮泵，它的工作速度不怎么快，就是加油门也不会有明显改善，而且还不能长时间的加大油门会烧坏齿轮油泵。还有一种搅拌车的液压泵是柱塞式变量泵，这种搅拌车在运输过程中一般速度较慢，但在卸料时，转速快，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.

　　定量泵和柱塞式变量泵在外形上也是有区别的，柱塞式变量泵外形尺寸比定量泵要大一些，结构上也更为复杂，对于搅拌车卸料一定要注意一些问题。

　　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.
               

　　混凝土搅拌车在装料时尽量不要装太满，要预留一些空间让粉粒扩容，要注意在装料时避免一些杂物混入搅拌罐内，因为这样会使卸料管堵塞，影响卸料速度和剩余率。

　　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.

　　中科聚峰混凝土搅拌车在卸料时，如果空压机有异常声响，应踩下离合器，关闭发动机，关闭取力器，直到故障排除才能继续卸料；还有就是在卸料时，一定要注意压力表的变化，整个卸料过程中作业人员都不能离开现场，避免压力过高现象的发生。在空压机工作时，在空压机的侧面应避免站人。提速时加油门要均匀。在平时搅拌车不用时一定要保持罐内的干燥清洁；在车辆维修时，一定要注意防止零件的碰撞，避免敲击，以免对零件造成损坏、变形、磕碰、划痕等。吸料口和底部距离可以调整，一般在30-50mm。切记不能用外接气源口排气。

　　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.

　　当空压机加压过程中因其他原因而停止空压机工作时，应关闭前后仓的近期球阀，然后把外接气源打开，过一会再关闭外接气源，打开前后仓的进气球阀。

　　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.

　　在卸料后冲洗车辆时，上下扶梯要抓紧扶手，身体严禁接触转动部位。冲洗完车辆后要将水箱阀门关闭，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.

　　每天下班后要对车辆做整体检查，发现故障要及时维修。

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

　　对于搅拌车卸料的注意事项一定要牢记，这样才能延长搅拌车的使用寿命，是可以带给我们更多收益的!如您还有其他问题欢迎咨询中科聚峰混凝土搅拌车网站。

　　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.
