Do you know why the gas station disables the phone?

1, the phone used in the petrol station, will produce a fire phenomenon
In the use of mobile phones will find this phenomenon, when the phone calls, the surrounding electrical interference is relatively large, such as the radio instantaneous noise, TV screen interference, etc., the main reason is the phone calls or phone calls, around the phone The main line, such as the antenna, circuit boards, panels, etc., will produce induced electromotive force, the electromagnetic field is the strongest, and the magnetic field is the strongest, the conductor in the magnetic field, the storage tank calibration methods includes: shell, cable, circuit board, internal line, Especially the components on the phone, the resulting induced electromotive force is the strongest induction electromotive force will produce the induced current, if the phone antenna is not connected, the phone inside the circuit board contact is not good, the battery contacts are likely to produce loose phenomenon At the same time, in the mobile phone signal electromagnetic field items will also produce static accumulation, static electricity is also the main cause of the phenomenon of ignition.
2, the gas station can form explosive gas
Gas station is a special place, likely to cause gasoline, natural gas and other explosive gas leakage, especially in the process of refueling oil and gas generated in the air, especially in summer, high temperature, gasoline volatilization, resulting in high concentration of oil and gas stations Gasoline is the most dangerous in liquid fuels. Gasoline is a mixture of hydrocarbons containing 5 to 12 carbon atoms, lighter than water and insoluble in water, volatile at room temperature, temperature probe calibration than air, so easy to accumulate In the low-lying, with the air to form an explosive mixture, the explosion limit of 1.3% to 6%, petrol steam minimum ignition energy is only 0.2 mJ, so any small sparks or naked eye can not see the static electricity will lead to space gas explosion combustion.
Mobile phone in the call or in the process of mobile phone switch, the internal will produce sparks. Oil and gas diffusion when all-pervasive, once into the phone, you may encounter a spark, and this spark is enough to ignite the explosion within the limits of explosive gas Fire accident occurred.
3, the mobile phone signal electromagnetic field will affect the fuel system computer motherboard work stability
Mobile phone in the call, a strong mobile phone signal electromagnetic field will be connected with the portable fuel transfer pump in the power supply lines, communication lines on the induced electromotive force, that is, the formation of interference pulses, interference pulse into the tanker and control machine, will affect the refueling equipment computer Motherboard work stability, which will cause the program is not running properly, crash, data loss, parameter changes, measurement is not accurate and some difficult problems.

Reminder self-refueling anti-static

In the car when the temperature probe calibration, we all know that a try is to use the refueling gun to the car refueling process can not call the car to turn off these safety knowledge is a lot of people know, but especially in the north, air dry Cold, is the static season, in the gas station to use the gas station dispenser gun self-refueling, if not pay attention, these hidden static electricity may cause a fire or explosion. How to eliminate static electricity?
To prevent electrostatic hazards, in the design of self-service tanker has been taken into account, so the tanker designed to provide the place to discharge.In general, the tanker on the metal keyboard is directly in contact with the ground, the owner before the need to refuel In the keyboard to enter their own petrol station automation system information, this process is equivalent to carrying the static electricity on the discharge, eliminating the body carrying static electricity.
In addition, the autonomous tanker also has a circular electrostatic discharge device, the above will remind you to touch before hand to release static electricity, the process is actually to remind you through its friction, the release of the body carried by the static , To prevent the next in the process of filling the hidden danger.

Refueling machine prices simply talk about the working principle of the tanker

   The petrol station management system is the core equipment of the gas station. In the era of increasing the number of cars and motorcycles, the number of tankers is increasing every year. The tanker can be divided into two types: self-priming pump fuel tanker and submersible fuel tanker , The following tanker price is simple under the two tanker their working principle:
    Self - priming pump fuel tanker works
Lifting the oil gun, the switch signal into the computer device to start the motor at the same time open the solenoid valve, the motor drive pump oil into the pump, pressurized oil and gas separation, the gas was discharged from the machine, the oil into the automatic tank gauge systems to promote the piston for reciprocating motion. The flowmeter drives the indexing plate in the sensor and generates a pulse electrical signal into the computer unit The flowmeter piston outputs a certain number of pulsed electrical signals each time a cycle is passed through a fixed volume of oil and into the computer Operation shows the realization of the measurement and control of the amount of oil through the measurement of oil through the electrostatic transmission hose, oil gun from the oil tank to the oil supply.
    Submersible pump fuel gas station management software working principle
The oil pressure signal is sent to the computer device, the electromagnetic device is opened after the computer device is processed, and the oil supply signal of the submersible pump is sent to the electric control device, and the electrical control device starts the submersible pump oil supply. The high pressure oil enters the flow meter through the filter The flowmeter pistons each time a cycle is passed through a certain fixed volume of oil, the sensor outputs a certain number of pulsed electrical signals, the flowmeter sends a pulse to the computer, , Into the computer device to calculate the operation to achieve the measurement and control of oil consumption.After the measurement of oil through the static electricity oil hose, oil gun from the oil tank to the oil supply.

In the use of gas station management system when you need to pay attention to some of the details of the problem, often these details of the problem and led to a lot of big problems, so the operation of this device is still very skilled grasp of the job, in the use of diesel fuel tanker Time must first check whether the equipment oil spill, to keep the machine clean, so that refueling more clean and tidy, but also regularly clean up the fuel card management, so that the function of the machine will not be affected in the actual operation also need to pay attention to a lot of Problems, these problems in the equipment have a detailed description, must be observed, the operation will be more secure.

submersible fuel pump become a lot of mobile equipment indispensable items, but also nowadays the most intense material, like this product how to be able to enter the mobile device on the need for a professional machine, the tanker is the best professional refueling machine, when the refueling More convenient, but also more helpful to the staff, this product in the use of time to have full control of technology, when the refueling will be more clean and tidy.
High intelligence era Many industries will infiltrate such a technology, tanker also infiltrated such a technology, intelligent way of refueling, the staff more helpful, we can see in many gas stations have the kind of fixed refueling equipment, as long as Input costs, refueling equipment will automatically generate the amount of automated fuel management system in the number will automatically stop after the number, this intelligent equipment to a large extent the release of more labor, but also save a lot of costs, but also their own refueling , As long as the smart terminal on the card can be their own fuel, very convenient and more time-saving.
