Refueling machine common problems and maintenance methods

First, the refueling machine does not turn on or open when not open

1, put down the oil qiang, press the keyboard to check whether there is a response, no response to check whether the power supply is normal.

2, check whether the shift lock is opened, the keyhole should be aligned with the red dot.

3, the tanker has a delay function, the last shutdown to the next boot time must be 2 to 4 seconds.

Two, quantitative without stopping

Unit price, density, coefficient...... Such functions, should be input before the zero after the input quantitative value.

Three, boot does not produce oil

1. Check whether the oil level of the tank is lower than the bottom valve of the double door.

2. Check whether the pipeline is seriously leaking.

3, the bottom valve is stuck or blocked, at this time the sound of the tanker is heavy, the oil and gas separator exhaust is scarce, check the bottom valve and pipeline.

4, the pipeline is long, the oil level is low, the vacuum can not reach, reducing the suction.

Four, the flow of large and small

Pipeline leakage, or oil surface and bottom valve usually, a large amount of gas in the route causes oil output to fluctuate.

5. Oil leakage from the exhaust of the refueling machine

1. Check whether the large float of the low pressure chamber is damaged by oil intake and whether the oil return hole is blocked.

2. Pipeline intake.

3, repeatedly boot without refueling, long time boot without refueling, can also cause the exhaust hole drainage.

Six, the accumulation is not allowed

Check whether the mainboard battery is normal.

Seven, less oil

The pipeline leaks, and a lot of gas is discharged with the oil.

Eight, more oil

Check that the meter is working properly
