Versatility: All oil tank trucks can be redesigned into chemical trucks and various heating/insulation series tanks. All models can be equipped with computerized fuel dispensers. We provide a wide range of registered tonnage options to meet diverse user needs. High-pressure gas leak detection is applied to guarantee structure integrity.

To ensure the cleanliness of the tank truck, the tank and oil delivery system must be cleaned regularly. The inner and outer joints at both ends of the delivery hose should be frequently lubricated with oil for easy assembly and disassembly. Clean the oil hose immediately after each operation to keep the pipe interior clean.

The use and maintenance of the oil pump must strictly follow its specific operation and maintenance manual.

Before fueling operations, the grounding rod must be inserted into damp ground. The static grounding tape of the oil tank truck must touch the ground, and excellent static conductivity must be maintained throughout the entire operation process.

The safety valve and filter screen of the tank truck must be checked and cleaned frequently.

The oil tank and piping system must be cleaned periodically. Regularly inspect all connections of the piping system to ensure they are secure and reliably sealed.

Static grounding tapes must be installed according to regulations. If static electricity meets highly concentrated residual flammable gases inside the vehicle, an explosion may occur. The static tape effectively eliminates static hazards in friction-prone areas like the chassis, ensuring personal safety.

Installation: Install the static tape directly onto the metal parts of the chassis. After a period of use, when the bottom part becomes worn, you can lower the rubber strip from the top adjustment point.

Advanced Safety: Users with appropriate conditions can install an Oil Tank Truck Static Grounding Alarm System.

Strict Prohibition: It is strictly forbidden to fill fuel into the tank truck under high-voltage power lines.

Avoid the "External Spark Gap" (Hanging Fire) Method: When an engine spark plug has severe carbon deposits, that cylinder will fail to work properly. Drivers sometimes use an external gap method (leaving a 3mm–4mm gap between the spark plug and the high-voltage wire) to increase the spark energy and force the cylinder to work. However, this temporary method can easily fall off. If there is leaking gasoline on the cylinder block, it can instantly trigger a fire. The correct action is to clean and maintain the spark plug in time; avoid using this hazardous method.

Insert the grounding rod into the ground to complete the "earth connection." If the ground is dry, pour water to make it damp and ensure good conductivity. Check the grounding chain to ensure it is in full contact with the road.

Open the control box door of the fuel truck, and check all valve handles to ensure they are in the closed position (vertical position).

When using the oil pump for the first time, there is no priming oil inside. You must pre-fill it with 10 liters of oil through the oil inlet.

Check the lubricant level in the gearbox; it should align with the lower edge of the oil level plug hole. Add gear oil if it is insufficient.

Check the gearbox shift lever to ensure it is in the neutral position. Check the Power Take-Off (PTO) control lever position to ensure it is horizontal and facing right. Check the throttle controller and set it to the minimum.

Vehicle maintenance is not just about changing engine oil; this is a narrow misconception. Oil tank truck maintenance is a broad concept that includes:

• Fluid & Filter Care: Changing and cleaning fluids and filters for various engine systems (engine oil, gear oil, brake fluid, automatic transmission fluid, power steering fluid, windshield washer fluid, battery water, oil filters, fuel filters, air filters, cabin filters, etc.).
• Wearable Parts Replacement: Maintenance of belts, batteries, brake pads, ball joints, clutch plates, and shock absorbers.
• Vehicle Aesthetics: Truck washing, exterior paint care, interior trim care, etc.

Proper maintenance preserves vehicle performance and extends its service life. Below are key operational safety details:

• Monitor the working status of all dashboard gauges while driving.
• Check whether the steering system is operating normally during transit.
• Verify that the handbrake and foot brake function properly.

The mobile fueling truck features a truck-mounted computerized tax-controlled fuel dispenser. Oil is pumped into the dispenser via the vehicle's oil pump. The dispenser measures fuel accurately by "Liters" or by "Input Amount." Alternatively, a flow meter can be installed. This type of tank truck offers unmatched flexibility and acts as a genuine mobile gas station servicing cities, suburbs, mines, docks, airports, stations, and rural roads where fixed gas stations are unavailable.

More Fuel Truck

1. The tank truck must be equipped with dedicated fire extinguishers, a dragging ground chain, and an earth grounding rod. The chain must touch the ground while driving. The rod must be inserted into damp ground during loading or unloading.
2. The tank manhole must be tightly sealed. Discharging valves and pipes must be leak-free. The vent hole must remain unobstructed. Clean the pump inlet filter screen frequently. Reattach the dust caps to both ends of the delivery hose immediately after use.
3. The carburetor and exhaust pipe of the internal combustion engine must not backfire. The exhaust pipe should be installed at the front of the vehicle.
4. Staff are strictly prohibited from wearing shoes with iron nails. Smoking and open flames are strictly forbidden near the tank truck.
5. When parking, stay away from fire sources. Choose shaded areas during hot seasons. Do not park under big trees or high-voltage lines during thunderstorms. A dedicated guard must watch the vehicle during intermediate stops.
6. If an operator needs to enter the tank for maintenance, open flames are strictly prohibited. Reliable safety protection measures must be implemented, and a dedicated safety monitor must stay outside the tank.
7. All electrical devices on the vehicle must be well-insulated, and sparks are strictly forbidden. Work lighting inside or under the vehicle must use safety lamps below 36V.
8. If the sedimentation tank freezes, never use fire to thaw it. Use hot water or steam to melt the ice, or drive the vehicle into a heated room to thaw.
9. When performing maintenance under the vehicle, turn off the engine, engage the handbrake, and wedge the wheels securely.
10. Road testing after repairs must be conducted by a qualified driver. No passengers or cargo are allowed on the vehicle, and a temporary test license plate issued by the traffic department must be displayed.
11. When parking on a slope, engage reverse gear for downhill parking, and engage first gear for uphill parking. Use triangular wooden chocks to wedge the tires tightly.

• Chassis & PTO: The chassis carries the tank. Since the engine drives the oil pump via an installed PTO and drive shaft, operations must be precise. Improper operation will destroy the PTO.
• Flow Issues: If the oil discharge is slow or cannot pump out, check and clean the safety valve and filter screen immediately.
• Loading Limit: The oil volume should not exceed the rated load capacity (calculate according to oil density).
• Ball Valves: Keep media clean to protect the sealing rings. Do not leave ball valves half-open or half-closed for long periods as it degrades the seals. Keep handles closed during driving.
• Winter Protection: Clean the inlet screen regularly. Keep the breather valve clean to avoid tank deformation. In winter, drain any water inside the self-priming pump completely to prevent the pump body from freezing and cracking. Use soapy water to clean the tank body before interior maintenance if necessary.

Symptom: The engine stalls automatically when releasing the accelerator pedal or while the vehicle is in motion.

Root Cause: The engine's idle speed is unstable when transitioning from non-idle to idle speed.

Specific Reasons: Accelerator pedal malfunction, out-of-sync signals between the crankshaft and camshaft position sensors, fuel pressure faults, control unit (ECU) signal errors, or incorrect injection timing.

Action: Check the numerical value variations during the transition from non-idle to idle status.

Symptom: The engine runs normally under no-load conditions but accelerates slowly and struggles on uphills under load. The RPM fails to reach its maximum even when the accelerator pedal is fully depressed, or there is a lag/fluctuation during acceleration.

Specific Reasons: Excessively high or low fuel system pressure, poor injector atomization, faulty sensor signals, insufficient fuel injection volume, incorrect injection timing, low cylinder compression pressure, or a blocked exhaust pipe.

Electronic controlled diesel engines can fail to start due to multiple factors, resulting in no initial combustion or hard starting. Follow these diagnostic steps:

• Fault Codes: Check for diagnostic trouble codes (DTCs). If present, troubleshoot based on the code definitions.
• Starter Inspection: Check if the engine turns over during starting.
• If the starter does not rotate, troubleshoot the starting system. Check battery charge, terminal connections, starting circuits, fuses, and the ignition switch. If the starter spins but the engine does not turn, it is a mechanical engagement fault between the starter and engine.
• If the starter spins at a normal speed but the engine won't fire, check the fuel injection and air intake systems.
• (Note: For electronic fuel injection engines, do not pump or fully press the accelerator pedal during startup, as this will only increase instantaneous RPM and boost fuel consumption).
• Pedal Test: Disconnect the accelerator pedal harness. If the engine successfully enters a stable idle state, the accelerator pedal is faulty.
• Visual Inspection: Inspect the air intake pipelines for any air leaks.
• Fuel Circuit Check: Check fuel pipe connections, signs of air ingress, and fuel quality.
• Wiring Harness: Check all wiring connections for looseness or poor plug contacts.
• Sensors: Verify sensor functionality, check for loose or broken wiring, and check the synchronization signal between the crankshaft and camshaft.
• Injectors: Check for injector control signals from the ECU. If absent, check the fuses, wiring, and ECU. If signals are present, check the spray/atomization pattern of the injectors.
