为了保证搅拌车的正常运行，充分发挥设备的效益，对搅拌机进行正常的维修保养。在使用的前期只要对新的搅拌机进行定期保养，基本上没有问题。搅拌机使用两年以上时，不必定期更换一些易损件。哪些零件需要不定期更换呢？下面来看看吧。

In order to ensure the normal operation of the mixer and give full play to the benefits of the equipment, the mixer shall be maintained normally. In the early stage of use, as long as the new mixer is regularly maintained, there is basically no problem. When the mixer is used for more than two years, it is not necessary to replace some vulnerable parts regularly. Which parts need to be replaced irregularly? Let's have a look.

不定期更换搅拌机机油。一般情况下，厂家在行驶5000-15000时会要求用户更换润滑油，而在行驶5000时则需要更换增压混合器的发动机型号。如果搅拌机驱动力不高或一直停机，每半年更换一次机油。当然，如果驾驶环境和油质良好，换油周期和时间可以适当延长。

Change the mixer oil from time to time. Generally, the manufacturer will require the user to change the lubricating oil when driving 5000-15000 km, and the engine model of the supercharger mixer needs to be changed when driving 5000 km. If the driving force of the mixer is not high or the mixer has been shut down, replace the oil every six months. Of course, if the driving environment and oil quality are good, the oil change cycle and time can be appropriately extended.

不定期更换制动油。制动油具有吸收空气中水分的特性，搅拌机制动器的液压系统必须使制动油与大气连通才能正常工作。随着时间的推移，刹车油会吸收水分，在高温下会变成气泡。搅拌机制动时，如果油路中有气泡，制动油将不能正常工作，制动效率将降低。因此，应根据气候、运行环境、季节变化和工作条件及时检查制动油，并及时更换。

Change the brake oil irregularly. The brake oil has the characteristic of absorbing moisture in the air. The hydraulic system of the mixer brake must connect the brake oil with the atmosphere before it can work normally. As time goes on, the brake oil will absorb water and become bubbles at high temperatures. When the mixer is braked, if there are bubbles in the oil circuit, the brake oil will not work normally and the braking efficiency will be reduced. Therefore, the brake oil shall be timely checked and replaced according to the climate, operating environment, seasonal changes and working conditions.

机油滤芯是用来过滤杂质的，所以应该和机油一起更换。如果不更换，机油就无法过滤，由于机油中的杂质，导致搅拌车内部零件加速磨损。不定期更换搅拌机空气滤芯。如果滤芯严重堵塞，进气阻力将增大，混合器的发动机功率将降低。

The oil filter element is used to filter impurities, so it should be replaced with the oil. If it is not replaced, the engine oil cannot be filtered. Due to the impurities in the engine oil, the internal parts of the mixer truck are accelerated to wear. Replace the air filter element of the mixer from time to time. If the filter element is seriously blocked, the air inlet resistance will increase and the engine power of the mixer will decrease.

同时，由于空气阻力的增大，也会增加汽油的吸收量，导致混合比过浓，这使得自动上料搅拌车运转更差，油耗增加，并且容易产生积碳。平时应养成经常检查搅拌机空气滤芯的习惯。

At the same time, due to the increase of air resistance, the absorption of gasoline will also increase, resulting in excessive mixing ratio, which makes the mixer run worse, increases fuel consumption, and is prone to carbon deposition. The habit of frequently checking the air filter element of the mixer shall be formed at ordinary times.

每两年或行驶50000时更换一次制动油，在选择和更换制动油时要记住：不要混合不同类型的制动油。由于配方不同，混合后的制动油会降低制动油指数。

Change the brake oil every two years or 50000 km. When selecting and changing the brake oil, remember: do not mix different types of brake oil. Due to different formulations, the mixed brake oil will reduce the brake oil index.
