No matter the new concrete mixer or the old concrete mixer, the operators are required to carry out irregular maintenance in the use process, so as to ensure that the mixer has long-term and efficient performance and will not be abandoned halfway. Then, which parts of the concrete mixer can be replaced irregularly? The analysis is as follows.

　　1. 不定期更换搅拌车机油

　　1. Change the mixer oil irregularly

　　一般来说,国内销售的自然吸气搅拌车引擎模型需要用户在5000- 15000更换润滑油,和涡轮搅拌车引擎模型中需要替换的5000,如果江南app平台官网 车不可能已经停止了,每隔半年来取代石油。当然，如果司机所在的环境和油品质量还不错，可以适当延长换油周期和时间。

　　Generally speaking, the engine model of the naturally aspirated mixer sold in China requires the user to change the lubricating oil between 5000 km and 15000 km, and the engine model of the turbo mixer needs to replace 5000 km. If the concrete mixer cannot be stopped, replace the stone oil every six months. Of course, if the driver's environment and oil quality are good, the oil change cycle and time can be appropriately extended.

　　2. 不定期更换机油滤芯

　　2. Change the oil filter element irregularly

　　机油滤芯的作用是过滤杂质，所以应该用机油代替。如果不更换，机油就不会被过滤，而且由于机油中的杂质，发动机内部部件磨损得更快。

　　The function of oil filter element is to filter impurities, so oil should be used instead. If it is not replaced, the oil will not be filtered and the internal parts of the engine will wear faster due to impurities in the oil.

　　3.不定期更换搅拌车的空气滤清器元件

　　3. Replace the air filter element of the mixer irregularly

　　如果过滤器堵塞严重，进气阻力就会增加，搅拌器的发动机功率就会降低。同时,由于空气阻力的增加,它也将增加汽油的吸收,导致太厚混合比,这将使搅拌卡车的发动机的工作条件更糟糕的是,和燃料消耗量的增加也将容易导致碳沉积。平时应养成经常检查搅拌车空气滤清器滤芯的习惯。

　　If the filter is blocked seriously, the intake resistance will increase and the engine power of the agitator will decrease. At the same time, due to the increase of air resistance, it will also increase the absorption of gasoline, resulting in too thick mixture ratio, which will make the working conditions of the engine of the mixing truck worse, and the increase of fuel consumption will also easily lead to carbon deposition. At ordinary times should develop the habit of checking the air filter element of the mixer frequently.

　　4. 不定期更换搅拌车刹车油

　　4. Change the brake oil of mixer irregularly

　　刹车油的特点之一是它能吸收空气中的水分。搅拌器的液压制动系统需要使制动油与大气相通，才能正常工作。随着时间的推移，刹车油会吸收水分，在高温下变成气泡。因此，制动油应根据气候、作业环境、季节时间和作业条件等及时更换其质量性能。

　　One of the characteristics of brake oil is that it can absorb water in the air. The hydraulic brake system of the agitator needs to connect the brake oil with the atmosphere in order to work normally. As time goes on, the brake oil will absorb water and become bubbles at high temperature. Therefore, the quality performance of brake oil shall be changed in time according to the climate, working environment, seasonal time and working conditions.

　　一般主张:每两年可行驶5万的时间更换，并且在选择和更换刹车油的时间时要牢记:不同类型和不同企业的刹车油不要混在一起。由于配方不同，刹车油的混合会导致刹车油指数下降。

　　General proposition: it can drive 50000 km every two years, and should keep in mind when selecting and changing brake oil time: different types and brands of brake oil should not be mixed together. Due to different formulations, the mixing of brake oil will lead to the decrease of brake oil index.

　　5. 不定期更换搅拌车的防冻液

　　5. Change the antifreeze of the mixer irregularly

　　如果长时间不更换防冻液，防腐蚀、防锈、防结垢等功能会降低，导致搅拌车冷却系统失效，甚导致腐蚀。一般情况下，防冻液通常每1.5 - 2年更换一次。

　　If the antifreeze is not replaced for a long time, the anti-corrosion, anti rust, anti scaling and other functions will be reduced, resulting in the failure of the mixer cooling system, or even corrosion. Generally, the antifreeze is changed every 1.5 - 2 years.
