After-sales maintenance and working principle of concrete mixer truck

The concrete mixer truck is a special truck used to transport concrete for construction. Because of its shape, it is often called a snail truck. These trucks are equipped with cylindrical mixer drums to transport the mixed concrete. During transportation, the mixing drum will keep rotating to ensure that the delivered concrete will not solidify. Next, let's take a look at the after-sales maintenance and working principle of the concrete mixer truck.

After-sales maintenance of concrete mixer truck.

1. Reasonably determine the protection period. The concrete mixer truck maintenance period refers to the distance mileage or time for vehicle maintenance. In the actual use process, the owner should refer to the maintenance period recommended by the automobile manufacturer, and make appropriate adjustments to the maintenance period in combination with the concrete mixer truck's technical conditions and operating conditions. Generally speaking, if a new car is used under good road conditions, it does not need to be maintained too frequently, and the maintenance period stipulated by the manufacturer can be used as the upper limit. However, if the technical condition of the 8x4 concrete mixer truck is poor, or the operating conditions are bad, the maintenance cycle should be appropriately shortened.

2. Make full use of free testing. The free inspection activities launched by concrete mixer truck manufacturers are very beneficial to car owners. Car owners can use these detection methods to conduct detailed physical examinations of their favorite cars and discover and eliminate some potential faults in real-time. This saves the high maintenance and maintenance costs that may arise in the future.

3. Crash the repair assembly as little as possible. Many concrete mixer truck owners have this feeling that a certain assembly of their favorite car is out of control after a breakdown and maintenance, which makes the CNG concrete mixer truck enter the maintenance period prematurely. The reasons for this phenomenon mainly involve the assembly skills of repairers and the quality of accessories. Therefore, it is best to avoid dismantling and repairing the assembly and use various advanced technical maintenance equipment and methods to perform maintenance-free maintenance on the concrete mixer truck, to avoid unnecessary damage to the concrete mixer truck assembly and components, and improve the quality of maintenance, and then reduce the total maintenance cost.

How concrete mixer truck works.

1. Concrete mixer truck mixing function principle

The power take-off drives the hydraulic motor of the hydraulic pump to rotate through the small transmission shaft and drives the mixing barrel to rotate through the reducer. During the concrete transportation process, it is necessary to keep the concrete mixer truck mixing tank rotating at a low speed of 1-3 revolutions per minute to ensure the uniformity of the concrete and prevent concrete segregation, which is called mixing.

2. The principle of the concrete mixer truck charging function

When the concrete mixer truck is loading concrete, the speed of the mixing tank is high, 6-10 revolutions per minute. Concrete enters the mixing drum from the nozzle through the feeding system, and flows to the middle and lower part of the mixing drum under the guidance of the spiral blade. Note that the rotation direction of the tank body should be consistent with the rotation direction during transportation, otherwise the concrete will be unloaded during transportation.

3. The principle of the unloading function of the concrete mixer truck

When the 6x4 concrete mixer truck is unloading, the engine transmits power to the mixing tank through the power take-off, hydraulic pump, reducer, etc. And drive the tank body to rotate at a speed of 3-14 rpm. Driven by the spiral motion of the concrete blade, the concrete blade moves toward the mouth of the barrel and is discharged through the discharge hopper of the concrete mixer truck. At this time, the rotation direction of the tank body is opposite to the feeding direction.

4. Principle of cleaning function of concrete mixer truck

The concrete mixer truck water tank is pressurized by the cylinder of the brake system, and the water flows through the pressurized cleaning mixing tank system, feeding port, discharging system, etc.
