Tanker structure and function in accordance with the differences can be used for a variety of categories.

In terms of the size of the oil transport capacity can be divided into general transportation capacity (the amount of oil is 40 ~ 60L per minute) of the tanker and the large flow (the amount of oil is 80 ~ 90L per minute) natural gas dispenser.
If you press the number contained in each refueling tanker refueling gun unit or can be divided into single gun tanker, guns and more guns refueling tanker.
By refueling tanker pump source can be divided into self-priming and submersible pump dispenser containing the.
In addition, according to the different functions of the special auxiliary tanker have mobile tankers, tanker car, suspension-free island refueling system with refueling vapor recovery function, adjustable set a different label contaminated fuel oil machine, and the host computer networking or controlled tanker, and China's Fiscal diesel fuel dispenser and so on.

The role of small tanker spill

For the analysis of the various parts of the small fuel management systems, thereby enhancing the understanding of the small tanker. Introduced the case of a small tanker vane pump and oil pump, etc. It should be noted in the previous article. Works as well as the analysis of fault diagnosis now we look at the role of the relief valve in the pump and its main role.
Relief role is:
High pressure relief valve within the pump chamber of a door leading to the low pressure chamber, which is mainly played the role of protection and limit the maximum pressure of the hydraulic system of the fuel monitoring system, and can adjust the output of tanker traffic.
Relief works:
When the motor is started, the oil pump, pressure oil from the oil pump flow positive zone and oil separator P relief valve port open at this time if the oil gun, pressure oil to the oil separator, pressure relief valve is closed, the pump the positive pressure and negative pressure zone pass each other; when the oil gun is closed, the pressure in the hydraulic system rises rapidly, the oil pressure relief valve overcoming the force of the spring, the spool shifted to the right, high pressure oil through the relief valve P and O port flow to the pump suction area, to achieve a petrol pump cycle.
Increased spring force, can increase the maximum pressure of the hydraulic system. Without relief, when the hydraulic system pressure is higher than a certain value. System most book weak links will be destroyed.
When the pressure relief valve adjustment screw clockwise twist, the pressure required to open the relief valve increases, most or all of the flow of oil and gas separator. Output increased tanker traffic; when the adjusting screw counterclockwise twist, the pressure required to open the relief valve is reduced, some oil through the relief valve back to the pump suction area, external output flow decreases.

Oil-leakage problem and solutions

1. The oil machine motor fuel management softwareinsulation breakage due to internal leakage;
2. Water or junction box wiring board insulation caused by decreased ability;
3. The external power input line Popi also in contact with the oil machine shell;
4. The machine internal circuits due to leakage caused by other reasons;
5. The machine does not have a reliablefuel management systemsand ground leakage protection circuit;
6. oil machine leakage, can easily cause fire and personal injury accidents, such as found in oil-leakage, must wind up immediately after stopping the leakage site and find out so completely solve the problem before being put into use again

Temperature calibration temperature scale established standard equipment types

Temperature measuring instruments and work with standard temperature test, generally a standard method of comparing standard thermometer was seized by the thermometer, that comparison done. Due to the large temperature range specified temperature scale, interpolation different temperature zones of different instruments, but the actual temperature measuring instruments for its application temperature range is different, so the different temperature zones and measuring instruments type its measurement methods are different. Various industries and regions thermometer traceable to standard equipment in various industries and regions, the thermometer calibration used in the construction industry can be traced back to the local metering station and then traced to the Chinese China Institute of Metrology temperature reference, can also be traced to China Building Science School building energy and environment Test Center, and then finally traced to the China Science and Chinese Academy of reference gasoline meter measurement. Temperature and the length, mass, time, current, luminous intensity, amount of substance (mole) and known seven basic physical quantities. Thermodynamic temperature (symbol T) is the basic physical hand, its unit is Kelvin (Kelvin symbol K), defined as the thermodynamic temperature of the triple point of water, 1 / 273.16. As the previous definition of the temperature scale used and 273.15K (freezing) to represent the difference between the temperature, so that each method remains. By definition, equal to the size of degrees Kelvin, the temperature difference can also use Celsius or Kelvin to represent.
