How to eliminate the emergency fault and routine maintenance of small refuelling vehicles

Refueling vehicles are also called mobile refuelling vehicles and are mainly used to provide on-site refueling services for various types of automobiles. Since fueling vehicles are fuel-laden for a long time, they are high-risk vehicles and regular maintenance and repair work is necessary.
1. Refueling chassis maintenance, refueling vehicles generally use Dongfeng, Liberation and Fukuda chassis, need regular visit to Dongfeng, Liberation and Auman service station.
2. The special equipment for refueling trucks. Special equipment for tankers includes tanks, network management systems and power take-off equipment.
3. Every day, the fasteners must be inspected and the grease must be cleaned.
4. Need to detect whether there is oil leakage and leakage in the interface part of the tank before exiting the vehicle. Whether the upper cover is covered as required, the amount of lubricating oil, the amount of fuel oil, cooling water, braking by hands and feet, steering device, instrument, lighting , Tyre pressure, tire nuts, etc.
5. Inspection and monitoring of various items in the refuelling vehicle, including instrumentation, steering system, brake system, engine, chassis, tank and other abnormal sounds and abnormal odors.
6. The following items need to be checked after taking the car: Tire and nut tightening, remove the inclusions in the tire tread, check for oil leakage, water leakage, air leak, check the condition of the leaf spring, if the drive shaft bolt is loose, check the tank Body appearance and pipe network system for tank cars.
Because of the special characteristics of the operation of refueling vehicles, regular and irregular maintenance and maintenance are very necessary and accidents cannot be neglected. The following is a common troubleshooting method summarized by Hubei Chenyang, for reference only.

No.

Refuelling car failure phenomenon

Possible causes of rapid resolution

1

Abnormal suction, no suction or suction

No oil in the pump

Refueling 10L Suction depth exceeds 5m Exceeded the scope of use of the vehicle The ball valve is not open Position adjustment Ball valve switch

2

Vacuum indicates low or no indication

Suction pipe partially sealed

Keep the seal tight

Oil pump impeller clearance increase inspection, repair oil pump vacuum table damage replacement

3

Vacuum indicates high value (4Mpa)

The suction pipe partially obstructs the cleaning filter and cleans the suction pipe

4

Pressure gauge has no value (or lower)

Part of the outlet pipe is not sealed tightly and the sealed tight pressure gauge is damaged and replaced.

5

Abnormal pump

According to the oil pump instructions

6

Power box noise

Car pressure is not enough, the power box is not on file

Pneumatic power take-off box will be sufficient to make the barometer read more than 0.3MPa

Poor air seal, power take off box is not connected

Keep the seal tight

The air chamber is damaged and the power box is not attached

Overhaul chamber

Too little oil in the power take-off box or impurities in the oil or replace the lubricating oil Retrieving, cleaning, replacing worn parts

7

Speed ​​box abnormal noise

Lubricating oil in the gear box is too little or has impurities

Refueling or replacing lubricants Gear box wear and tear Removal, cleaning, replacement of worn parts

8

Tank can't put precipitation

Impurities clog the dust-collecting pipeline. Clean the winter tank with excess water. Freeze or melt the ice with hot air or hot water.

9

The flow machine does not rotate and the working pressure of the oil pump is too high

Impurities stuck in the flowmeter should be disassembled and cleaned. The position of the meshing of the two gears is incorrect. Reinstall the gears with reference to the flowmeter manual.
