Concrete mixer truck interior parts and exterior maintenance

A concrete mixer truck is composed of an automobile chassis, mixing drum, transmission system, water supply device, full power take-off, front and rear brackets of mixing drum, reducer, hydraulic transmission system, feeding and discharging system, operating mechanism, and other parts. Concrete mixer truck is now widely used in both construction sites and road maintenance. Let's talk about the internal parts and external maintenance of the 6x4 concrete mixer truck.

Concrete mixer truck internal parts maintenance.

1. Water tank and condenser

Due to the long-term driving of the dry vehicle, some sundries, catkins, etc. will accumulate on the water tank and the front of the condenser of the concrete mixer truck. When there is too much accumulation, if it is not cleaned up in time, it will directly affect the heat dissipation function of the water tank and condenser. Especially in the summer when the ambient temperature is high, the engine temperature may be too high or even boil. In severe cases, because the heat of the piston cannot be dissipated between the piston and the cylinder, the belly is too large, and the gap between the piston and the cylinder is reduced or even disappears, resulting in a hard pull, resulting in cylinder scuffing, which is very important.

2. Concrete mixer truck oil filter element

The function of the concrete mixer truck oil filter element is to filter impurities, so it should be replaced together with engine oil. If it is not replaced, the oil will not be filtered, which will lead to accelerated wear of the internal parts of the 8x4 concrete mixer truck engine due to impurities in the oil.

3. Hydraulic oil and reducer oil

The hydraulic oil and reducer oil should be replaced once every 100 days or so after the new concrete mixer truck is used. No. 68 wear-resistant hydraulic oil should be used in the oil storage tank of the hydraulic system. It is recommended to use No. 46 hydraulic oil in cold regions. The reducer uses No. 90 heavy-duty gear oil, and it is recommended to use better quality oil.

4. Cabin filter

Attention should also be paid to the use of air conditioners. Air conditioners are used in both summer and winter. Generally, before the arrival of these two seasons, the air conditioners need to be cleaned and cleaned. The air conditioner filter should be cleaned or replaced regularly during use, otherwise, the clogged filter will prevent and reduce the air from entering the evaporator. Although the air conditioner is turned on, it still does not feel cool. Some concrete mixer trucks still have been accompanied by an odor, for air-conditioned vehicles without a cabin filter. When you feel that the air volume of the air outlet is reduced or there is a peculiar smell in the car after turning on the air conditioner, please go to a professional repair shop to clean the evaporation box. After cleaning, you will feel that the air inside the car is fresh and the coolness is increased, which relatively improves the driving comfort of the concrete mixer truck. The air filter of the concrete mixer truck generally needs to be replaced every 15,000 kilometers and cleaned once every 5,000 kilometers.

5. Air filter in concrete mixer truck

Because the concrete mixer truck is in use, if the air filter is too dirty, the amount of air entering the cylinder will be reduced, resulting in a decrease in the power performance of the concrete mixer truck, and the speed cannot be increased. In addition, the quality of the air filter should be reliable, if the filter is not clear, fine dust will enter the cylinder. It will increase the wear between the piston and the cylinder, thereby reducing the overall service life of the engine, which is very important.

External maintenance of concrete mixer truck.

1. Car paint maintenance

For car paint care, generally in spring, the weather is neither cold nor hot, which is very suitable for car paint care. The simplest car paint care is waxing, and the longer and more effective one is to perform glaze beauty. Most concrete mixer trucks don't have time for a second paint treatment, but regardless, proper paint care can extend the life of your vehicle.

2. Timing belt maintenance

The timing belt needs to be replaced regularly. The main function of the timing belt is to drive the valve mechanism of the engine, so that the intake and exhaust valves of the engine can be opened or closed at an appropriate time, to ensure that the cylinder of the engine can normally inhale and exhaust air. gas. In some models, the timing belt is also responsible for driving the water pump. The belt of the CNG concrete mixer truck is a rubber part. With the increase of the working time of the engine, the timing belt and the accessories of the timing belt, such as the timing belt tensioner, the timing belt tensioner, and the water pump, will wear or age. Therefore, for any engine equipped with a timing belt, the manufacturer will have strict requirements to replace the timing belt and accessories regularly within the specified cycle, and the replacement cycle varies with the structure of the engine. Generally, the concrete mixer truck should be replaced when it has traveled 60,000 to 100,000 kilometers. The specific replacement cycle should be based on the maintenance manual of the concrete mixer truck.
