Fuel tank truck for sale

Tanker Tanker tank according to manufacturers will choose the right size engine horsepower, the principle is the high-powered trailer large jar, small horsepower drag small jar. Therefore, in line with national standards out of a tanker reason insufficient horsepower will not exist. As there will be lack of engine power, the customer may be in the tank taappeared in daily use among some of the issues would lead to lack of motivation, customers can focus on the following aspects in mind.

A  oil tanker truck engine fuel supply shortage

1 tank truck signs of engine no-load operation, if the throttle, the speed increase only slowly; when there is a load, the engine obviously weakness, and easy to stall, but no exhaust smoke; when the work overload, stalling and slightly black smoke.

2 reasons 1) the pump cover oil passage control valve is jacked up dirt or wear and tear, resulting in closed lax. 2) injection pump improperly adjusted. 3) When acting governor speed is too low or failure. 4) diesel filter is clogged or Road pipeline leak. 5) grades of diesel does not meet the requirements.

3 treatment methods: 1) Check the control valve repair or replacement parts depending on the circumstances. And adjustment to conditional repair shop governor. 2) re-adjust the fuel injection pump. 3) Adjust stop oil supply rocker cable length. 4)

Clean diesel filter, sealed pipeline road. 5) Press the appropriate choice grades of diesel season, and by the sedimentation process.

Two fuel supply advance angle adjustment inappropriate

1 sign 1) when the engine is at low speed, rough engine operation, and a clear Knocking sound; when throttle speed can rapidly improve, more Knocking sound obvious, but weakens, and high coolant temperature.

2) when the engine is running, the exhaust pipe black smoke, the cooling water temperature is high. Engine overheating, the engine sometimes put guns to increase the "throttle", the speed is increased slowly.

2 reason oil supply too early or too late.

3 treatment or re-adjust the fuel supply advance angle replacement, repair badly worn pad adjustment, wheel body parts and other pieces of camshafts.

Three fuel tank truck insufficient air supply

1 signs: no engine load operation, serious black smoke, the sound muffled, power down, especially during acceleration, release the air cleaner and the intake pipe connecting pipe, the phenomenon of black smoke was reduced.

2 reasons 1) dirty air filter is clogged, a serious shortage of the amount of air entering the cylinder, the gas is not completely burned. 2) coke exhaust pipe is blocked. 3) turbocharger speed drops.

3 treatment methods: 1) Clean the air filter regularly. 2) periodically clear the exhaust coke, and remove undesirable combustion engine malfunction. 3) timely maintenance turbocharger turbine inspection and sealing means.

Four fuel tank truck engine valve clearance adjustment inappropriate

1 fuel tank truck signs of engine no-load operation, intermittent black smoke exhaust pipe, valve has a slight "da da" percussion

Reason 2 valve clearance adjustment too large, the intake valve and exhaust valve opening night off early, the total valve opening time is shortened, not the result of exhaust emissions, insufficient air intake, engine power decreased, exhaust black smoke.

3 treatment prescribed valve clearance adjustment, then periodically check and adjust valve clearance.

Five fuel tank truck aircraft engine temperature is too high or too low
1 signs of engine coolant temperature is too high or too low, insufficient power.
2 reasons 1) the water temperature is too high is usually due to prolonged overload operation, cooling serious scale, or excessive oil caused by oil too late. 2) the water temperature is too low to start soon occur in the winter.
3 processing method 1) Avoid prolonged overload locomotive operation, remove the cooling system scale, reduce the amount of oil, adjust injection timing.
2) After starting the car in winter, the water temperature should be raised to 40 ℃ after the start, the normal operating temperature should be maintained at 75 ℃ ~ 90 ℃.

Six fuel tank truck leak caused by wear and tear parts

1 signs intake manifold, exhaust pipe leak sound; cylinder pad peripheral (edge) with bubbles occur; severe blow at the gasoline filler neck, the exhaust pipe to take the blue smoke, oil consumption sump abnormal.

2 Cause valve and valve seat closed lax; cylinder head screws tightened standards fails; severe burning oil.

3 processing method) cleaning, scraping reaming, grinding valve and valve seat. 2) The cylinder head fixation surface is uneven or warped, should repair scraping or grinding, ensure that the cylinder liner is installed projecting amount within the specified range,
According to the prescribed order and tightened cylinder head nuts. 3) the cylinder liner and piston group parts wear is not serious, it can replace the piston rings, cylinder liner while rotating 90 ℃ installation, if the gap is more than a predetermined value,
Cylinder boring should replace the oversized piston.

Seven fuel tank truck moving parts Loose or seizure

1 signs of engine running black smoke; parking, crank the engine felt great resistance.

2 reasons 1) fixed plunger adjustment arm loose, adjust the lever on the fork oil loose fastening 2) of the plunger body and wheel jamming occurs, the plunger spring force is too weak or broken.

3 processing method) related fastening parts 2) Repair worn rolling element 3) replacement of standard size and elasticity of the plunger spring.
