Summer tank truck maintenance guide, a must-see when using the truck!

After entering the dog days, thunderstorms frequently occur and the weather becomes hotter. This is not a good thing for tank trucks. Rain washing and sun exposure will accelerate the aging of the tank truck’s paint and parts, which will affect the service life of the vehicle. Regular maintenance is essential. The following related staff will show you what are the precautions for the summer maintenance of tank trucks.

1. Appearance inspection

Check the surface of the tank for collision, depression, deformation, corrosion, etc. If a large area of ​​collision depression or deformation is found, it should be stopped immediately and repaired by a qualified maintenance unit; and for dangerous goods transportation tank trucks , And also pay special attention to check the signs, check whether the ribbon signs, the words “No Pyrotechnics”, the dangerous goods signs, the dangerous goods signs, etc. are incomplete or unclear, irregular or incomplete. If the above conditions occur, they must be replaced in time .

2. Car body cleaning

Visual inspection is very important, and regular cleaning is also indispensable. Carefully clean the body before and after using the car, because the dirty body may cause a short circuit in the circuit, and may even corrode the parts, thereby affecting the use. Keeping the car body clean will not only keep the tank car beautiful, but also extend its service life.

3. Chassis maintenance

The chassis is the closest part to the ground. It is most affected by road conditions. Generally, the damage is the most serious. The wheel shell may even be loose and perforated. Therefore, you must pay attention to the cleaning and rust prevention of the tanker chassis, in principle, every 3 months Just do a maintenance. Also be careful not to wash the body and chassis with alkaline cleaning fluid, so as not to affect the anti-rust effect and shorten the anti-rust time.

4. Ignition start

Many drivers should have encountered a situation where the engine is not easy to start, and this is especially true in rainy days. Even if they barely start, they are weak. This is likely to be the leakage of the ignition system due to moisture. Of course, it is also possible that it is raining and becoming cooler, causing the hot air in the distribution panel to condense into water droplets and causing small internal floods, so the ignition cannot be started normally.

If it is for the above reasons, it is best to dry the inside and outside of the distribution panel and the wires first, and then use a special desiccant spray can to spray the desiccant on the distribution panel cover, battery connector, spark plug, high-voltage wire and ignition coil, etc. After that, it can start normally.

5. Glue strips can not be ignored

The maintenance of tanker rubber strips is easy to be overlooked, but don’t underestimate these rubber strips. In addition to decorating the body, they also play an important role in sealing the compartment. Once aging and cracking, it will seriously affect the waterproof and sound insulation performance of the tanker. . Therefore, it must be cleaned and maintained regularly with a special adhesive strip cleaner, and replaced in time if it is aging or falling off.

In addition to daily maintenance, troubleshooting is also a very important part. The following editor lists the common faults and causes of tank trucks, troubleshooting methods, etc., hurry up and check your own car for a self-check!

Malfunction Cause of issue Elimination method
Tank collapsed 1. Unloading speed is too fast

2. Breathing valve failure

3. The small cover of the observation hole is not opened when unloading

4. The oil and gas recovery pipeline is not opened

1. Reduce the discharge speed or open the small cover of the observation hole or open the oil and gas recovery pipeline

2. Clean or replace the breathing valve

3. Open the small cover of the observation hole

4. Open the oil and gas recovery pipeline

Liquid leaking from the breathing valve 1. The temperature of the liquid in the tank is too high

2. Breathing valve failure

1. Reduce the temperature of the liquid in the tank

2. Clean or replace the breathing valve

The bottom valve cannot be opened 1. The bottom valve control air pressure is too low

2. The bottom valve controls air leakage

3. The bottom valve is damaged

1. Adjust the pressure of the oil and gas separator

2. Repair the leaking pipeline

3. Repair or replacement

The bottom valve cannot be closed 1. Dirt agglomeration in the valve

2. Cotton yarn and other sundries entangle the valve plate

3. Damaged valve gasket

1. Remove lumps

2. Remove debris

3. Repair or replace

The ball valve does not turn well or cannot be fully opened and closed 1. Dirt agglomeration in the valve

2. Cotton yarn and other sundries entangle the valve plate

3. Damaged valve gasket

1. Remove lumps

2. Remove debris

3. Repair or replace

Poor unloading 1. The discharge pipe and valve are blocked

2. Breathing valve failure

3. Gas phase imbalance inside and outside the tank

4. The liquid viscosity is too high

5. The filter is clogged

6. The oil pump fails

1. Remove blockages

2. Repair or replace

3. Reduce the unloading speed or open the small cover of the observation hole or open the oil and gas recovery pipeline

4. Reduce liquid viscosity

5. Clean the filter or replace

More leftovers 1. The car parking place is too steep

2. There are foreign objects in the pipeline

1. Park on a flat place

2. Clean up foreign objects

Of course, these are just selected precautions. The maintenance of tank trucks is a matter of university, and these are far from enough. Everyone must pay more attention to avoid unnecessary losses in daily driving. In the hot weather, Lin Yu warmly reminds owners and friends to take a break and not to drive fatigued.
