The timing belt is a very important external part of the concrete mixer. Whether it can be used normally also greatly affects the use of my mixer. Therefore, the timing belt needs to be replaced regularly. Now let's talk about its maintenance!
The main function of the belt timing belt is to drive the valve distribution mechanism of the engine, so that the inlet and exhaust valves of the engine can be opened or closed at an appropriate time to ensure that the engine cylinders can normally breathe in and exhaust.
In some models, the timing belt is also responsible for driving the water pump. The belt of concrete mixer is a rubber part. With the increase of engine working time, the timing belt and its accessories, such as timing belt tensioner, timing belt tensioner and water pump, will be worn or aged.
Therefore, the manufacturer has strict requirements for engines equipped with timing belts. The timing belts and accessories should be replaced regularly within the specified period. The replacement period varies with the structure of the engine. Generally, the concrete mixer should be replaced when it runs 60000~100000 km. The specific replacement period should be subject to the maintenance manual of the concrete mixer.
In addition, special maintenance shall be paid attention to. This is a kind of coping maintenance for the concrete mixer after a major abnormal event. For example, if the vehicle has been overturned into the river, when it is salvaged, if there is no major damage to the machine parts, a coping maintenance shall be carried out before reuse.
For another example, in case of an engine runaway accident, when the runaway is stopped, the crank linkage mechanism and other relevant parts must be subject to a coping maintenance, so that the technical status of these parts can be completely restored to normal before restarting operation.
The above is the maintenance method for the timing belt of the concrete mixer. Pay attention to the maintenance when using the car, so as to increase its service life and better use. Follow us http://www.zkhntjbj.com , learn more!
