As long as the new small concrete mixer is regularly maintained for the first two years, there will basically be no problem. When the small concrete mixer is used for more than two years, some easily worn parts will not be replaced regularly. What parts need to be replaced irregularly? Let's introduce:
1. Replace the engine lubricating oil irregularly
The oil is changed every half a year when the small mixer is driven for - 50000 kilometers, but the user usually requires the engine to be changed every half a year when the mixer is driven for - 5000 kilometers. Of course, if the driver's environment and oil quality are good, the oil change cycle and time can be appropriately extended.
2. Replace the oil filter element irregularly
The function of the oil filter element is to filter impurities, so it should be replaced with the oil. If it is not replaced, the oil cannot be filtered, resulting in accelerated wear of internal parts of small concrete mixer engine due to impurities in the oil.
3. Replace the air filter element irregularly
If the filter element is blocked seriously, the air inlet resistance will increase and the engine power of small concrete mixer will decrease. At the same time, due to the increase of air resistance, it will also increase the amount of gasoline absorbed, resulting in excessive mixing ratio, which will worsen the running state of small concrete mixer engine, increase fuel consumption and easily produce carbon deposition. At ordinary times, the habit of checking the air filter element of small concrete mixer truck should be formed.
4. Replace the brake oil irregularly
One characteristic of brake oil is that it will absorb water in the air. The brake hydraulic system of small concrete mixer truck can operate normally only if the brake oil is connected with the atmosphere. Over time, the brake oil will absorb water and turn into bubbles at high temperature. When bubbles appear in the brake oil circuit of small concrete mixer truck, the braking efficiency will decline. Therefore, the quality and performance of brake oil should be checked and replaced on time according to the climate, operating environment, seasonal changes and working conditions.
General recommendation: replace it every two years or when driving 50000 kilometers, and remember when selecting and replacing brake oil: do not mix different types of brake oil. Due to different formulations, mixed brake oil will reduce the index of brake oil.
5. Replace the antifreeze from time to time
If the antifreeze is not changed for a long time, the functions of anti-corrosion, anti rust and anti scaling will be reduced, which will cause the failure or even corrosion of the cooling system of small concrete mixer. Generally speaking, the antifreeze is generally replaced every 1.5-2 years.
