The main difference is that the diesel engine cylinder pressure

The main difference is that the diesel engine cylinder pressure in the mixed gas is fired, not lit. The diesel engine when the air entering the cylinder, compressed air in the cylinder to the end, the temperature at 500-700 ℃, pressure 40-50 atm. When the piston approaches top dead center, high-pressure pump on the engine petrol dispenser pump at high pressure to the cylinder injection diesel, diesel oil to form a fine grain, mixed with air high pressure high temperature combustion diesel hybrid gas itself, violent expansion, generating power, push the piston down acting . At this point the temperature 1900-2000 ℃, pressure up to 60-100 atmospheres, great power, therefore, widely used in diesel engines on large diesel vehicles.

To the public for the pipeline to achieve precise control of hydraulic

To the public for the pipeline to achieve precise control of hydraulic, completely changed the oil pressure with engine speed change phenomenon. Its main features are the following: 1, injection timing and fuel metering completely separate, timely injection pressure and injection process is controlled by the ECU. 2, can be based on engine fuel dispenser pumps operating conditions to adjust each cylinder injection pressure, injection start point, duration, so that the pursuit of optimal control point fuel injection.But with the development of modern technology, these disadvantages diesel are gradually being overcome, and now is not the limousine diesel engines have already started using the.

Display dispenser security system operation

Safety: quantitative tests require oil to flow unrestricted through the nozzle into the container, some of which must be maintained when the requirements of the submersible pump running. Electronic system control submersible pump operation, and at different time intervals routinely open the pump, perform leak detection function. These intervals are configured with the stations, such as the type and length of the line is changed. Hence gear type pump the need for clear procedures to ensure that test equipment during installation or container is not in a safe position, the pump is not running. And when you start testing requirements pump must operate. System Action: When the leak detection sensors, electronic systems may need to close submersible pump. Different types of electronic systems have different procedures to confirm no leakage state, and the pump returns to normal operation. Technician needs for each tested models perform special after the test procedures.

fuel dispensing equipment

Censtar china fuel dispenser volatile strong light oil tanker is done, so, when using the fuel dispensing equipment standard metal gauge verification diesel fuel dispenser inevitably has the problem of oil volatilize quantity affect the test result.Volatile quantity and the size of the tanker traffic size, environment temperature and humidity.Measured in the test standard gauge and tankers flowmeter in the oil temperature. diesel fuel dispenser gauge the temperature measurement, the tanker is not easy to measure the temperature of flow meter, general oil gun exit temperature instead of the temperature of the fuel dispensing equipment flowmeter.And the distance is related to the length of the hose, hose is greatly influenced by ambient temperature, so censtar china fuel dispenser the temperature measurement error (low).

Diesel fuel flow meter where the strengths of performance

The main work of calibration of vertical cylindrical tanks is to determine the radius of the circle plate. The main method of current confining diesel flow meter gauge method, capacity comparison method, optical plumb method, optical reference line method and optical triangulation method, each method is closely related with the measurement tool, the ultimate goal is to determine the radius of the circle plate. With the improvement of processing mode, new measurement tools of mathematics, we can expect a new calibration method will emerge.

Portable fuel pump

Portable fuel dispenser is a new precision measurement, computer-controlled DC power supply or AC 220v power supply, can be directly printed notes, ultra-portable, ultra-durable portable fuel pump. fuel dispenser can be fixed directly to the tanker, oil delivery trucks, the transport planes, refueling anytime accurate measurement.

Tanker tanker used;

(1) on-board pump refiner Oil and temperature probe calibration is equipped with a filter, which consists of copper mesh and blankets mesh sets, separator side wall has a triangular cover can be removed filter. The filter of the combined pump refiner is installed in the inlet port. Submersible pump type tanker installed with a special filter box, open the end cap to remove the filter. The filter should be cleaned regularly (at least once a month) with gasoline to clean the copper mesh cover, damage should be replaced, and remove dirt from the oil machine to protect the pump and flow meter.
(2) on-board pump and the combination of the pump on the relief valve adjustment screw used to adjust the pump pressure, and then adjust the tanker's oil discharge. Factory has been adjusted. After long-term use, such as the amount of oil dropped, the adjustment screw can be tightened in order to increase the pressure of the pump, but not more than 0.3MPa, so that the amount of oil to meet the requirements.
(3) Combination of pump-type gasoline meter is only suitable for underground tanks, such as the use of high oil tank, there will be exhaust pipe oil phenomenon, then be sure to block the exhaust pipe.
(4) the use of oil guns to avoid the oil gun with the oil pipe percussion by oil containers, press the switch and other abnormal operation, so as not to damage the oil gun, causing oil spills. To check regularly, tighten the screw on the tubing to prevent the oil pipe root loose, damaged, underground storage tank regularly cleaned to keep the oil clean.
(5) the accuracy of the adjustment of the machine should be "JJG443-86 metering tanker test procedures," the relevant provisions.
(6) overhaul the electrical part of the power must be cut off, should not take electricity repair. Do not damage the explosion-proof surface when opening the explosion-proof case. When the explosion of dust inside the dust should be clean, the cable seal should be good, metal pads, gaskets can not be lost, the number of screws is not missing, tightened and reliable to ensure that the electrical components of the explosion-proof performance.

Whether the gas station management system will be hit by fire, depending on whether the scene of oil and gas, and whether the impact of spark or open fire, ignite these oil and gas. In fact, we do not have to worry too much, the gas station is not a big fire, fear of fire caused by the explosion, I think we are worried about this is also. The inside of the submersible fuel pump has been associated with protective measures, such as the electrical part and the mechanical part of the oil is separate and independent. The electrical part is sealed and the oil part is ventilated to prevent oil and gas accumulation. The real fire in the early can be controlled, the gas station has a clear fire safety division of labor, employees will regularly receive training and exercise, and fire extinguishers, fire blankets, fire sand, are complete, this is the national mandatory.

How does the tanker flow slow?

1. retail fuel dispensers fueling slow; 2. tanker to speed up the oil gun to automatically jump.
For your question seems to be such a phenomenon: the tanker refueling oil flow rate can not be too fast, if too fast, the oil gun will automatically jump (that is, oil gun click about no oil, then fuel card management pump is still rotating).
This is because the general tanker used in the oil gun is self-styled oil gun, self-styled oil gun is characterized by 1. In the bottom of the oil gun has a small hole (inlet), the intake or less intake When the self-styled (jaundels); 2. Vice valve problems also jump gun (this problem is relatively less than the first one). You said this phenomenon is called "oil guns self-styled sensitive."
Treatment: 1. Remove the gun nozzle, check the gun under the hole is smooth, not smooth, including the ventilation pipe broken / debris blockage, etc., to exclude these phenomena; 2 to see the gun into the air (and Gun mouth into the hole connected to the hole) is blocked, whether the normal connection with the gun, etc .; 3. The above two points most likely to occur, generally caused by oil and other dirty, troubleshooting rate of about eight or nine percent. If not, then check the oil gun deputy valve

How long will the refueling station refuel?

Under normal circumstances, Sinopec multi product dispenser unloading, the need for oil for 15 minutes before they can refuel it! Because the unloading process of the momentum, making the original deposition in the bottom of the debris particles suspended in the oil, if unloading oil immediately after the oil, the particles may be followed by the tank gauging equipment, affecting the quality of oil it! So pro, or to remember and so on Oh, unloading oil, do not rush to refuel!

Lubricant tanker in the refueling process often occurs in the case of pause

For many people who have just come into contact with the lubricating oil tanker, the use of refueling is not necessarily smooth sailing, and there are often small details that do not pay attention or do so, and the peening of the lubricating oil tanker is Very normal, there are a lot of people will mistakenly think that the quality of the electronic diesel fuel pump, but hard, in fact, not entirely. And then Xiaobian together to get a better understanding of the small mystery it!
     First of all we find the source of the pause fault where?
1. Lubricant tanker motherboard problems, which will cause the oil to love the organic pause can not refuel;
2. We use the power supply voltage is not particularly stable situation, the tanker will have a pause phenomenon, or the voltage is very low, lower than the normal output value.
3. We turn on the power, the boot button is not flexible, and sometimes contact is not efficacious, there will be no retail fuel dispensers.
4. If your line on the wiring board is not connected, it will be one of the reasons for the fuel tanker refueling pause.
    These are the more common causes of fuel pause, and we can according to some of the above tips and tips to distinguish self-help tank level gauge system in the refueling process often have a pause phenomenon specific reasons to find a suitable solution and methods.

In the use of self-styled refueling gun is what we need to pay attention to

Self-styled refueling in a self-contained refueling gun ensures that the oil gun is automatically shut off when the container is full to prevent media spillage. So what do we need to pay attention to when we use it?
    1, self-styled series of petrol station management system, can not be used in addition to light oil other types of media filling operations. Such as: heavy oil, acid, alkali and other properties of the liquid.
    2, the heavy duty fuel dispenser inlet thread can only be connected with the same thread of the pipeline connection, such as the screw standard will not be able to achieve a different seal, and easy to damage both sides of the thread even cause gun body rupture.
    3, the tapered thread by the threaded parts of the seal, the installation of the need to tie the thread tied to the amount of sealed packing. The flat body thread is sealed by the flat part and the O-ring is fitted at the root of the joint thread. No additional packing is required on the thread.

Disassemble refueling gun, teach you to know the refueling gun

On the tank automation system, the refueling hose only delivers fuel, fuel is pumped from the underground oil tank, extracted through the oil and gas separator, the flowmeter and then to the solenoid valve, and finally through the oil gun to the car fuel tank.
Conventional refueling machine is the use of self-styled oil gun, this type of oil gun design on the fuel dispensing meters structure, many users that ordinary self-styled oil gun is used to "steal oil", "oil" Otherwise, the self-styled oil gun on the air pipe connected to the self-styled device, the intake pipe is the oil gun "switch", once the oil (or oil-filled foam) submerged into the air pipe, self-styled device will close the gun Stop the oil supply.

The stockings are effectively filtered on the refueling gun

 In some of the less developed areas of traffic, although the use of ordinary gasoline, but some of the gas stations are very uncomfortable people. "Dirty oil" refers to the more colloidal gasoline, adding such a gasoline easily lead to fuel filter plug, fuel injector clogging and fuel spray bad phenomenon, a long time also easy to valve and Combustion chamber to form coke, resulting in the engine is not working properly. So before the trip, it is best to install in the car with a spare oil tank calibration software filled with oil, one to facilitate the highway can not find the gas station when the emergency can also be added to the "dirty oil", the replacement Gasoline filter, let go of "dirty oil" to replace the spare oil.
  In addition, it is best to buy a petrol filter funnel, used to filter impurities when gas station dispenser, if you can not buy gasoline filter funnel to prepare two pairs of stockings on the car, once the last resort in some places where traffic is not developed, Put the stockings on the refueling gun (at least two layers) to effectively filter impurities. However, it is advisable to choose PetroChina or PetroChina's own oil tank monitoring system when refueling in these areas.

Car refueling machine is a new way of service

There are many kinds of automatic tank gauge systems, although the function is almost, but in the way of diversity, car refueling machine is one of the way in the refueling will be more convenient to become a lot of field operations and the car in the event of failure when the best Help tools, the car will be a very common thing, in the high-speed car once there is no fuel is a terrible thing, but with the help of this device, the car can quickly enter a good state.
Car fueling machine has created economic value for many individuals, in the case of a lack of fuel in the car can use this equipment to refuel, its role will not be neglected in the gas station, it can be said more convenient than the gas station, more services it is good.
fuel transfer hand pump machines often run in different areas, there will be a lot of dust and weak acid substances, the equipment on the surface of the damage, it is necessary to always clean the equipment, keep the external clean, so that equipment to use more long.

Car fueling machine has the advantage of mobility

The function of the diesel fuel flow meter is obvious, in the actual refueling most in need of such equipment, so that refueling is more simple, but for the field of operations in the field, the refueling is subject to a lot of restrictions, can not directly to the gas station refueling , So that the production equipment has been a great impact, but the emergence of the car tanker greatly improved the impact of such a refueling more simple, while the production will be more helpful.
The biggest advantage of the auto fuel dispenser is that it can move, move to different places as needed, fuel the living equipment, support the normal operation of the equipment, and allow the field operations to proceed more quickly. The role of the tanker in time will be more Big, as long as a phone call at any time, greatly facilitated the work, but also to work shorter.
The working principle of the vehicle tanker is also the same on the gas station equipment, there are print receipts, tips, terminal equipment and many other configurations, so that the tanker can be very convenient to run, when the work will be more convenient.

Diesel tanker should also be cleaned regularly

Diesel automatic fuel dispenser works the same way as other tankers, but this tanker is better in performance, with all the features, especially the flow of statistical technology, is the most important function of the tanker, but also the tanker in the Automatic work principle on the best display, in the tanker before the work must ensure that the equipment function, in normal work conditions, the equipment can run the best, but also the most secure.
Diesel fueling machine must be carefully checked before work, the flow meter function is correct, the tank level gauge system is a very important function, the correct calculation of traffic, to ensure that the benefits, so every time to conduct a check, To ensure the effect.
Diesel fuel tanker should also be regular cleaning, fuel will have stains, long-term pollution in the pollution of the equipment under the function of a great deal of damage, it is necessary to carry out regular cleaning, especially the stains inside the machine, more serious The tip of the work will be subject to a certain impact, we must pay attention to clean.

The price of the tanker determines a lot of factors

The price of the car fuel dispenser is also very high in the market, although this product has a lot of manufacturers, but still very high in price, because such products in the high cost, the need to invest in human and material resources are very high, Out of a tanker need to pay the cost and technology to join is very high, after entering the market will certainly be higher, so when buying the tanker should be careful, especially for the performance must be concerned about the current tanker In function are the same, but in the performance requirements will be higher.
The performance of the portable fuel dispenser is related to the stability of the tanker, such equipment must be stable, only a stable equipment will have a better market, the stability of the equipment in the fuel when the time will be more convenient, but also more long , Which is the equipment must have the performance, the price of the tanker to a lot of content, the higher the price of the equipment in the performance of the better, the lower the price of the equipment in terms of performance will be limited, of course, the tanker The model is also a great impact on the price, the price is often a major factor in determining the merits of the product, once the product price is not very high, the performance will be affected.
Tanker prices are not the same in each of the manufacturers, the greater the cost of the product will be the higher the price, which is very sure, the price is the main factor reflects the merits of the product, the production enterprises in the production needs A lot of technology investment, especially the tanker such equipment, automatic refueling need high-tech technology, only high-tech technology can show a better way of working, of course, no matter how high the price is not decided to buy the product factors The
There are many kinds of tanker prices on the market, but also according to the type of tanker to the price, the difference between the size of the fuel tank, the higher the price will be higher, the lower the price will be low, at the price of concern The time should also be more concerned about the power, in the actual role of the power of a great impact, the work will be more convenient.

Car refueling makes refueling more efficient

Each product in order to meet the needs of the market, it is necessary to appear in different ways, in appearance also have different, according to the volume will have a different display, the portable fuel transfer pump as a very wide range of equipment, in many areas should be like this Equipment, especially in the outdoor work, even more need for such equipment, of course, manufacturers also need to design a different tanker, like a car refueling machine is one of the best, through the form of vehicles to refuel, Very convenient.
Car refueling machine is the best help outdoors, many machines need to work outdoors, and refueling is the biggest trouble, in order to make the refueling will not affect the normal work, we must use the car form of the tanker, when the refueling Will be more convenient, you can directly put the tanker next to the machine, refueling will be more convenient, when the refueling will also avoid a lot of problems, so that more secure oil tank monitoring system, refueling will automatically produce receipt, very formal, so Of the refueling way is no worse than the refueling form of the station, it can be said in the actual operation will be more efficient.
Car refueling machine needs a lot of accessories, in order to allow the tanker to be firmly installed in the car will use a lot of accessories, the effect will be better, and the tip is essential, only the tip of the complete installation of the refueling Machine is able to work well, which is the most important parts of the tanker, but also essential parts for refueling, of course, the car's tanker in the power is relatively small, after all, the car is limited, and low-power in the When used will be more secure, the tanker and the machine is a guarantee.
