As concrete mixers are made up of thousands of kinds of parts. With the increase in the use of time, the functionalities of various components have begun to slowly reduce the occurrence of varying degrees of wear, aging, corrosion and so on. Therefore, regular maintenance of the vehicle is to restore the best performance of the vehicle, prevent minor problems from becoming major problems, and ensure the safety of concrete mixer trucks, as well as better economy and longer service life. However, in daily life, due to the backwardness of repair methods, there are many misoperations in the daily repairs, which buries the hidden troubles of the accident, or causes the performance of concrete mixers to deteriorate, wear is accelerated, and the service life is shortened. Therefore, in order to ensure the safety of the vehicle and the goodness of the vehicle, we must learn the correct maintenance of the vehicle and avoid getting into the wrong zone.
In the face of the four most common misunderstandings on the market, here's a correction:
First, we must ensure that the engine goes down at normal temperature: The concrete mixer drives at the specified normal temperature to ensure the service life of the engine.
Second, do not blindly remove the engine thermostat: In the case of a high engine temperature if the blind thermostat removed, so that the engine is often working at a low temperature, resulting in concrete mixer car engine power decreased, accelerated wear, increased fuel consumption. In addition, the coolant can only be subjected to a large circulation, and the cooling intensity cannot be adjusted, and it is difficult to ensure that the engine operates at a suitable temperature. Do not blindly remove the thermostat.
Third, the engine with idling temperature: When using idling heating, due to lower speed, fuel due to poor low-temperature atomization, so that unburned fuel into the crankcase, flush off the oil film on the cylinder wall, it will also accelerate the wear of the parts. Therefore, after the engine of the concrete mixer starts for a few seconds, the application of fast idle temperature rises to improve the lubrication conditions of the engine.
Fourth, to ensure that the pump fan belt in the appropriate technical requirements: too tight belt will not only make it elongated or broken, shorten the service life of the belt, but also due to excessive tension, resulting in deformation of the concrete mixer truck shaft, water pump shaft Bending and early damage to the bearing.
