How much do you know about the maintenance of HOWO tank truck as a member of dangerous goods transportation vehicles? We all know that no matter what car needs maintenance, there will be misunderstandings in maintenance. Do you know the misunderstandings in the maintenance of HOWO tank truck?
Myth 1: always inflate the tire pressure very high. Many drivers like to adjust the tire pressure of HOWO oil tank truck very high, thinking that this can save fuel and overload. In fact, it is not. Too high tire pressure will reduce the tire grounding area, and the tread will be seriously worn, which will reduce the braking effect when braking. There is no doubt that this will affect driving safety; But too low tire pressure is not good. Too low tire pressure will accelerate the wear of tire shoulder, increase the fuel consumption of the vehicle, and also affect the driving safety and braking effect of the vehicle.
Myth 2: always fill the engine oil very full. Many drivers are always worried that the engine oil of HOWO tank truck is not enough, and they always fill it full. However, many people do not know that too much oil will increase the rotation resistance of the crank connecting rod mechanism, and will also increase the amount of oil splashed on the cylinder wall. Too much oil will also lead to increased carbon deposition in the combustion chamber and decreased engine power, thus affecting emissions. In fact, the amount of oil should not be too large, but it should not be too small. Generally, it should be added according to the scale on the oil scale. The oil level should not exceed the upper limit of the scale at most, and the lowest should not be lower than the lower limit of the scale. It is better to have the oil level in the middle of the scale.
Myth 3: the bolts of the HOWO tank truck are fixed too tightly. Generally, the tightening torque of the bolts in various parts of the oil tank truck is specified according to their diameter, pitch and purpose. If the specified torque is not reached, the bolts will loosen, and if the tightening torque is exceeded, the bolts will be stretched. We should know the tightening torque of the bolt when tightening the bolt.
Myth 4: I always think that the tightness of the accessory belt is better than the looseness. Many car owners believe that increasing the tightness of the accessory belt can improve the refrigeration effect of the compressor and the power generation of the generator. In fact, this practice is wrong. The accessory belt should be properly tensioned, because too tight the belt will overload the bearing, shorten the service life of the components, and cause the belt to break, which will eventually affect the normal use of the vehicle.
