How to choose a tanker

The fuel transfer hand pump is an indispensable product for work and life, bringing great convenience to everyone's life. Today's transportation equipment is essential and presents a rising trend, so the fuel is needed. Plus fuel when they need more professional equipment, can we save more time, and the tanker is such a device, when the fuel will be more fast, but this equipment needs not only the occasion Gas stations, in many enterprises also need such equipment, so we must choose the right tanker.
How to choose the auto fuel dispenser we take a look at the gas station is usually used in the relatively large power of the machine, the power will be faster speed, when the operation will be more rapid, a lot of services have a very good help, Of course, you can also choose the gun tip of the tanker, the actual use of the effect will be better, and faster and faster.

Use the tanker to pay attention to what problems

Each product is to appear in order to better serve the public, in the actual use of more labor to save, which is the purpose of enterprises to create products, like the emergence of the fuel dispensing machine, to a large extent to meet everyone The need for refueling, this way of refueling will be more convenient, the use of high-tech technology to make fuel more intelligent is the advantage of this product, so in many industries will use this product, so that the work efficiency is very large improve.
There are many types of gas station dispenser, each type of product has a very good effect, so also need to purchase, the greater the power of the product will be higher in the price, usually like this product are in the refueling Station use, to the staff and consumers a great convenience, the power of disaster when the fuel will be faster, but in the specific operation process also need to pay attention to the phenomenon of adding oil, in the busy time will appear This is the error, which is the attitude of the postgraduate in the work of the logistics of what kind of products, all with intelligent refueling equipment for everyone's work to bring great convenience.
Tanker in the work of the time should also pay attention to a lot of problems, especially in the safety of the problem even more attention to the fuel inside the tanker will encounter a fire, so when the fuel must be the first time the device flame Can be fueled, such things in a lot of gas stations will appear, the driver will not let the car trouble, so that once the consequences are very serious, the tanker should always clean, clean the product, keep the product performance, The product will not be contaminated.

Effect of Temperature on the Fuel Consumption of Tanker

The same quality of fuel at different temperatures when the volume is not the same, China's petrol station management system is currently ignoring this point. At present, the measurement results of the tanker on the market are mostly the value of the oil temperature at non-standard temperature, and the tanker has no volume temperature correction function technically. If the tanker does not consider the temperature change factor, the measured value is not the standard temperature of 20 ℃ volume, will inevitably affect the measurement of the value of the unity and accuracy, resulting in oil sales error. According to the International Recommendation OIML R117-1995 "Non-aqueous liquid measurement system", the gasoline flow meter can use the conversion device to modify the volume, the actual volume measurement results into the standard temperature (15 ℃ or 20 ℃) ​​under the volume For our country, the standard temperature is 20 ℃).

Self-styled refueling gun pressure sensing system

fuel transfer hand pump for kerosene, gasoline, diesel and other light oil filling operations. It has a separate body with the gun body of the sealed pressure of the working system, when the oil gun main valve to open high-speed oil flow through the return valve, due to the special structure of the valve assembly design will make pressure inside the system pressure.
temperature probe calibration When it is in normal working condition, its pressure-sensitive system will be through the pressure inside the tubing in the pipeline to continue to get gas to maintain the pressure-sensitive diaphragm up and down the basic pressure in a state of balance. When the filling surface rises and closes the ventilation port (at this time the container is full) pressure within the system will quickly increase the negative pressure, pressure sensor on both sides of the pressure loss on both sides of the pressure (upper negative pressure) The diaphragm will drive the switch card to the negative side of the movement of the bolt off the file, which in 0.3 seconds self-styled refueling gun to complete self-styled closure action.

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.
