The pull-off valve is a safety maintenance component planned for the safe operation of the tanker. It can maintain the tanker from being pulled down when the force of the tanker end is stretched, so as to avoid irreparable accidents. When the pull-off valve is broken under the action of external force, the two ends will separate. The two internal valves will be actively positioned to block fuel outflow, avoid leakage, and maintain the industrial safety of fueling equipment and gas station personnel.
The pull-off valve is a safety guarantee and vulnerable part for the safe use of fuel dispenser manufacturers. It is easy to fall due to external force or instant hydraulic impact during use. So in daily use, pay more attention: if it falls, it should be maintained and replaced in time. , It is strictly forbidden to install maintenance devices on the pull-off valve, do not disassemble the quick coupling, do not use the hose with cracks, to avoid leakage or falling, the fluid used must be clean and suitable fluid filtered through the filter.
The fuel dispenser control board announced the instructions to start the oil pump motor and turn on the solenoid valve. The oil in the oil tank is driven by the oil pump, and is delivered to the vehicle fuel tank through the oil filter, solenoid valve, flowmeter, and oil gun. When the oil gun is manually closed to stop refueling, put the oil gun back to the dispenser and hang up the start switch, or when the refueling amount and refueling amount reach the preset value entered by the keyboard, the control panel will announce the command, close the solenoid valve to stop the oil delivery, and the oil pump stops Running.
Poor contact of the power supply switch of the fuel dispenser will cause intermittent power supply of the fuel dispenser, especially when the motor of the fuel dispenser is started, causing the power supply voltage of the fuel dispenser to drop, and the operation of the fuel dispenser is momentarily abnormal, sometimes causing the following problems: the fuel dispenser stops when refueling; The operation of the main board of the machine is unstable and the data is lost; the electrical control part is damaged; the fuel dispenser lacks phase and the motor is burned out (the tax-controlled fuel dispenser has a lack of phase maintenance function).
