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. Change the mixer oil irregularly
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. Change the oil filter element irregularly
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. Replace the air filter element of the mixer irregularly
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. Change the brake oil of mixer irregularly
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.
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. 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，甚至导致腐蚀。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.
