1、 1-2 years "peak period"
The first two years of concrete mixer use are the "peak period" of life. It can be said that it is the best age for concrete mixer, which is equivalent to people's youth. During this period, people are full of enthusiasm, dare to break through and do, and don't seem to be tired. The same is true for the concrete mixer during this period. The vehicle is in excellent condition. As long as routine maintenance is carried out, there will basically be no problem. But for some concrete mixers with poor quality, the "peak period" is only about a year. Therefore, there will be no major quality problems in the first year of operation of the new car. However, some of the most easily worn parts of the concrete mixer used for more than two years should be gradually replaced.
2、 2-4 years "Microsoft period"
At this stage, the concrete mixer has initially entered the "Microsoft phase". It is no longer as vigorous as in the early stage. It seems that people reach middle age. Although they are still healthy, they sometimes have some minor diseases. During this period, some parts of the concrete mixer need to be replaced frequently to supplement energy.
First of all, it needs to replace new brake pads. The brake pad is the first line of defense for driving safety; According to experience, the brake pads will be seriously worn in about two years. At this time, the fuel pump should be cleaned or replaced. At the same time, if the concrete mixer does not run smoothly, the vibration damper of the truck should be checked. If the spring of the shock absorber loses its elasticity, it will be very dangerous to drive in rainy days.
Sand and gravel are the main components of concrete. They cause serious wear of concrete storage tank, inlet and outlet during operation. Generally, the service life of concrete storage tanks made of low alloy steel is 50000 ~ 80000 m3. The service life of spiral blade in concrete storage tank is only 30000 ~ 40000 m3. The concrete storage tank of ordinary mixer truck is generally made of high-strength low-alloy steel, which is 1 ~ 2 times higher than that of ordinary A3 steel. The working life of different materials is very different.
3、 4-6 years "menopause"
After four to six years of use, the mixer truck will gradually enter the "menopause". Just like people entering the "menopause" are emotionally unstable, cars in the "menopause" will also play games from time to time, and it is common to have some problems. During this period, many parts of the general mixer truck began to age, and small faults such as oil leakage and water leakage often occurred. The car should be overhauled frequently, and special attention should be paid to the inspection of daily maintenance. During this period, some smart car owners began to change cars
4、 6-8 years "Twilight period"
Cars at this stage, like the elderly in their 60s and 70s, "have three or six serious diseases and minor diseases every day", sometimes "forget things" and sometimes "strike". During this period, the owner must strengthen the maintenance of the vehicle and replace the vulnerable parts regularly. The owner needs to frequently check the vehicle condition at the maintenance station or maintenance center. Routine inspection and maintenance must be done before and after the vehicle is sent out.
5、 8-10 years "dangerous period"
During the period of eight to ten years, the mixer truck is in a "dangerous period" and may be "critically ill" at any time. For the car in this period, the owner had better let it stay in the garage for convalescence, or directly send it to the scrap Station to sell scrap iron.
After these five cycles, the life of the mixer truck will end.
