How to maintain the oil tanker trailer

As a member of the dangerous goods transport vehicle, how much do you know about its maintenance? No matter what kind of car needs maintenance, there are also misunderstandings in maintenance. Do you know the maintenance misunderstandings of tank trucks?

Tank truck maintenance

(1) First of all, it is necessary to understand and master the main structure, performance and functions of the tank truck. The special vehicle chassis of the Shandong tank truck manufacturer must go to the special car service station for maintenance or maintenance as required;

(2) An oil tank truck is usually composed of four parts: a special vehicle chassis, an oil tank body, a pipe network system, and a power take-off device;

(3) Drivers and friends who drive fuel tank trucks should do a good job in the routine maintenance of fuel tank trucks. They should do a good job of checking, cleaning, fastening and adding before leaving the car, during driving, and after receiving the car, so as to find the oil tank in time. Problems or potential safety hazards left by the car, so that the problems can be found in time and dealt with in a timely manner;

(4) Before leaving the vehicle, the diesel tanker manufacturer checks whether the oil tank body, pipe network, valves, etc. are leaking or leaking, whether the upper cover is closed as required, the amount of lubricating oil, fuel oil, cooling water, hand and foot system Movement, steering, instruments, lights, tire pressure, tire nuts, etc.

(5) Problems that drivers and friends should pay attention to when the tanker is running:

① Check the working conditions of each instrument while the tanker is driving;

② Check whether the steering system of the oil tanker is working normally during driving;

③ It is not normal for the oil tanker to check the hand and foot brakes during driving;

④ When the tanker is running, check whether the engine, chassis, and tank body have abnormal noise and odor during operation;

⑤Shandong oil tanker manufacturers use the parking time to do the following inspections of the oil tanker: touch the front and rear wheel brake drums with hands for overheating, check the tightening of tires and nuts, remove the inclusions in the tire pattern, check for No oil leakage, water leakage, or air leakage, check the condition of the leaf spring, whether the drive shaft bolts are loose, check the appearance of the oil tank body and the pipe network system of the oil tanker;

(6) The oil tanker regularly goes to the special vehicle service station for chassis running-in maintenance and maintenance.

Mistakes in tanker maintenance

Myth 1: Always over-inflate your tires. Many drivers like to adjust the tire pressure to a high level, thinking that it can save fuel and overload. In fact, you don’t know that if the tire pressure is too high, the ground contact area of the tire will be reduced, the tread will be worn seriously, and the braking force will be reduced. There is no doubt that this will affect the driving safety; but too low tire pressure is not good, too low tire pressure will accelerate the wear of the tire shoulder, and will increase the fuel consumption of the vehicle, which will also affect driving safety and The braking effect of the vehicle.

Misunderstanding 2: Manufacturers of diesel tank trucks always fill up the engine oil very much. Many drivers are always worried that the engine oil is not enough, so they always fill it up, but many people do not know that too much oil will cause Increasing the rotational resistance of the crank connecting rod mechanism will also increase the amount of oil splashed on the cylinder wall. Too much oil will also increase the carbon deposition in the combustion chamber and reduce the engine power, thereby affecting emissions. In fact, the amount of engine oil should not be too large, but it should not be too little. Generally, it should be added according to the scale on the oil scale. It is best that the oil level is above the middle of the scale.

Misunderstanding 3: Fix the bolts of the vehicle too tightly. Generally, the bolts of various parts of the tank truck have corresponding regulations according to their diameters, pitches and uses. The bolts will loosen when the specified torque is reached, and the bolts will be stretched beyond the tightened torque. When tightening the bolts, we must know the tightening torque of the bolts.

Misunderstanding 4: Diesel tanker manufacturers always think that the belt of the attachment is tighter than loose. Many owners of tanker think that increasing the tension of the attachment belt can improve the cooling effect of the compressor and the power generation of the generator. In fact, this kind of The approach is wrong. The accessory belt should maintain a proper tension, because if the belt is too tight, the load on the bearing will be too large, which will shorten the service life of the parts and cause the belt to break, which will eventually affect the normal use of the vehicle.
