Small concrete mixers will inevitably encounter various problems in use, such as speed loss. Now let's analyze the causes of speed loss of small concrete mixers.

1、导致小型混凝土搅拌车速度过慢，因为电磁阀间隙太大，使得供油不足，从而引起发动机掉速。

1. As a result, the speed of small concrete mixer truck is too slow, because the clearance of solenoid valve is too large, which makes the fuel supply insufficient, thus causing the engine to lose speed.

2、建议检查一下油品是不是出现变质，并且看一下集油品中有无杂质，检查油路是否堵塞。

2. It is recommended to check whether the oil is deteriorated, whether there are impurities in the oil collector and whether the oil circuit is blocked.

3、发动机使用燃油品质太差或燃油水含量过高，都会导致小型混凝土搅拌车发动机的功率不足，造成掉速现象。

3. Poor fuel quality or high fuel water content of the engine will lead to insufficient power of the engine of small concrete mixer, resulting in speed loss.

4、另外小型混凝土搅拌车的气门间隙不对、喷油定时有错、涡轮增压器损坏等，都会造成掉速。

4. In addition, wrong valve clearance, wrong fuel injection timing and damaged turbocharger of small concrete mixer will cause speed loss.

此外混凝土搅拌车运送混凝土的时间不能超过搅拌站规定的时间。运送混凝土途中，搅拌筒不得长时间停转，以防混凝土产生离析现象。司机应时常观察混凝土情况，发现异常及时通报调度室，申请做出处理。

In addition, the time for concrete mixer truck to transport concrete shall not exceed the time specified by the mixing plant. During the transportation of concrete, the mixing drum shall not be stopped for a long time to prevent segregation of concrete. The driver shall always observe the concrete condition, report to the dispatching room in time in case of any abnormality, and apply for handling.
