As a member of the dangerous goods transport vehicle, how much do you know about its maintenance? We all know that no matter what kind of vehicle needs to be maintained, there are misunderstandings in the maintenance.
|Do you know the misunderstanding of tank truck maintenance?
Misunderstanding 1: Always fill the tire pressure very high. Many drivers like to adjust the tire pressure to a high level. They think it can save fuel and overload. In fact, if the tire pressure is too high, the tire’s ground contact area will be reduced, and the tread wear will be serious, which will reduce the braking performance. Braking effect, 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 the tire shoulders, it will increase the fuel consumption of the vehicle, and it will also affect the driving safety and the vehicle's safety. Braking effect.
Misunderstanding 2: Always fill the engine oil very full. Many drivers always worry that the engine oil is not enough and always fill it up. But many people don’t know that too much oil will increase the crank connecting rod. The rotation resistance of the mechanism will also increase the amount of oil splashing on the cylinder wall. Excessive oil will also increase the carbon deposit in the combustion chamber and reduce the engine power, thereby affecting emissions. In fact, the amount of oil cannot be too large, but not 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. The oil level is above the middle of the scale.
Misunderstanding 3: Fix each bolt of the vehicle too tightly. Under normal circumstances, the bolts of various parts of the tank truck, according to their diameter, pitch and purpose, have corresponding tightening torques, and they cannot reach the specified torque bolts. Will loosen, and the bolts that exceed the tightened torque will be elongated. When we tighten the bolts, we must know the tightening torque of the bolts.
Misunderstanding 4: I always feel that the belts of the accessories are better than loose. Many owners of tank trucks think that increasing the tightening of the belts of the accessories can improve the cooling effect of the compressor and the power generation of the generator. In fact, this approach is wrong. of. The accessory belt should maintain proper tension, because too tight the belt will cause excessive load on 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.
