With the construction of high-rise buildings in the city, the concrete mixer truck plays an increasingly important role in the construction site. In order to ensure the normal operation of the small concrete mixer truck and give full play to the benefits of the equipment, the normal maintenance and repair of the concrete mixing tank should be carried out. As long as the new concrete mixer truck is used for the first two years, as long as routine maintenance is carried out, basically there will be no problem. When the mixer truck is used for more than two years, some easily worn parts will not be replaced regularly. What parts need to be replaced from time to time? Let's introduce the following:
1、 Change the engine lubricating oil of mixer truck irregularly
Under normal circumstances, the manufacturer will require the user to change the lubricating oil when driving 5000 km-15000 km, while the supercharged mixer engine model requires changing the lubricating oil when driving 5000 km. If the mixer does not drive very well or is always in the stop state, the oil should be changed 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 oil filter element irregularly
The function of oil filter element is to filter impurities, so it should be replaced with oil. If it is not replaced, the oil can not be filtered, resulting in accelerated wear of internal parts of the mixer engine due to impurities in the oil.
3、 Change air filter element of mixer truck irregularly
If the filter element is seriously blocked, the air inlet resistance will be increased and the engine power of the mixer will be decreased. At the same time, due to the increase of air resistance, the amount of gasoline sucked in will also be increased, resulting in excessive mixing ratio, which will make the running state of the mixer engine worse, increase fuel consumption, and also easy to produce carbon deposition. Usually should develop the habit of often checking the air filter element of mixer truck.
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 brake hydraulic system of mixer truck must make the brake oil communicate with the atmosphere in order to operate normally. Over time, the brake oil will absorb water and turn into bubbles under high temperature. When bubbles appear in the brake oil circuit of mixer, the braking efficiency will be reduced. Therefore, the brake oil should be timely inspected according to the climate, operating environment, seasonal changes and working conditions, and its quality and performance should be timely replaced.
General advice: change it every two years or when driving 50000 km. When selecting and changing the brake oil, you should also remember: do not mix different types of brake oil. Due to the different formulation, the mixed brake oil will cause the brake oil index to decline.
5、 Change the antifreeze of mixer truck irregularly
If the antifreeze solution is not changed for a long time, its anti-corrosion, anti rust and anti scaling functions will be reduced, which will lead to the failure of the mixer cooling system and even corrosion. Generally speaking, the antifreeze is replaced every 1.5-2 years.
