Small tanker Classification

Many types of small tankers, can be divided in different ways at several:
By tanker traffic is divided into: general and high-speed refueling tanker.
Different measurement display can be divided into: electronic display tankers, tanker and mechanical computer show that the mechanical refueling tanker; electronic dispenser with electronic counter instead of a mechanical counter, while increasing the photoelectric sensor, computer tanker is the use of computer-controlled counter, computer-controlled counter under computer control CPU in addition to completing a simple counting function, but also increased the operation and control functions, pricing function, preset amount of fuel liters or preset functions. mechanical pumpuses mechanical counter.
By proof structure is divided into: one-and explosion-proof isolation.
Measured according to the number of refueling unit is divided into: single gun tanker, tanker guns, more guns tanker;
Press the power pump types are divided into: the machine pumps and submersible pump fuel dispensing equipment
Carried by tanker into a different medium: methanol tanker, diesel tanker, gasoline tanker etc.

Persistence depends on a large tanker used daily maintenance

Safeguard vane pump, help enhance the life of a small tanker. To know nothing mechanical can permanently using it. Persistent machine using a large part depends on the process used for its maintenance is good or bad. So for those familiar with the use and maintenance of small tankers users, use and maintenance vane pump is generally no big problem. However, issues related to the use of those new users do not know where it is necessary to properly learn about.
A relief valve spring can not be adjusted too tight, or make tank calibration software pressure, noise and vibration increases, and increased pump bearing wear.
2, V-belt tension should be appropriate, the tension is too small, the belt slippery, causing oil or no oil shortage, but also easy to wear belt tensioning force is too large, the motor shaft and the pump shaft to bear additional load (axial direction of the vertical axis) increases, could easily accelerate the motor bearings,fuel monitoring systembearings and seal wear.

Precautions tanker safety inspection

1.A regular check tanker grounding, grounding device to see whether the specification, contact is good.
2, regular testing oil gun grounding resistance, grounding resistance is ≤10Ω, if abnormal, should be replaced or re-install the hose fittings.
3, regular testing whether internal tanker spill site, if any, should be resolved in a timely manner.
4, periodically check the tanker work sounds unusual, if abnormal, should be promptly excluded, then use.
5, periodically check the internal backup power supply tanker work, if not normal, it is timely maintenance.
6, regular testing tanker measurement accuracy is qualified, if unqualified, should be corrected in a timely manner to find quality inspection departments.
7, regular inspection is complete tanker seals, chip seal is intact, if not complete, it is timely to find the relevant departments or personnel to resolve.
8, regular inspection agency or self-styled refueling emergency stop mechanism is working properly, if not normal, it is timely to exclude or replace the corresponding parts.
9, regular check tanker power lines, power switches, each box is working proof, if normal, should be immediately removed or replaced corresponding parts.
10, regularly check whether the tanker exhaust flow, if unimpeded, could affect measurement accuracy electronic fuel dispenser, or endanger the safety of hydraulic pumps and other fuel nozzle manufacturers

measurement of the temperature

Standards of measurement of the temperature and the temperature of the test work, usually by being seized on a standard thermometer and method comparison standard thermometer, done that comparison. Due to the large range of gas dispensersscale temperature range specified interpolation different temperature zones of different instruments, but the actual temperature measuring instruments for the applicable temperature range is different, so the different temperature zones and types of measuring instruments which measurement methods are different. Various industries and regions thermometer traceable to standard equipment in all sectors and regions, thermometer calibration used in the construction industry can be traced back to the local metering station and then traced to China, China Institute of Metrology fuel dispensing hose reference, can be traced to China Building Science School building Energy and environmental Monitoring Center, and then finally traced to a Chinese benchmark China Institute of temperature measurement.

Temperature measurement calibration

Thermodynamicmarine fuel dispensers(symbol T) is the physical fundamentals hand, its unit 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 with 273.15K (freezing) to represent the difference between the petrol dispenser pump, so it retains all methods. By definition, equal to the size of degrees Kelvin, the temperature difference can also be expressed in degrees Celsius or Kelvin to represent. International Temperature Scale ITS-90 also defines international Kelvin (symbol T90) and the International Celsius (symbol t90)

temperature probe calibration

Move around the reflector so that the echo reaches a maximum angle of incidence corresponding to the point at this time is that the probes or the K-scale values. Material Velocity Calibration find R100mm described in accordance with a maximum reflected waves makes it possible to adjust the display range is displayed on the screen of the arc of the second echo select gate way for the double gate, A gate with an echo adjustment intersect, regulating B gate intersects with the second echo, adjust the speed of sound value makes the status line sound path measurement is 100, velocity values ??obtained at this time is the actual velocity values ??of the material. Probe Zero calibration measurement state maintained above the gate way to the positive or negative, so that the state regulate the fuel meters zero sound path measurement line again to 100, the probe zero value is zero at this time to get the value of the diesel meter. There are many oblique probe calibration method does not completely block the test stick using standard calibration, the calibration may be performed using the known depth of the hole, in theory, the reference reflecting body is smaller, the higher the accuracy of calibration, but the calibration difficulty is correspondingly increased. When using the calibrated orifice by measuring the depth of the hole and the horizontal position, to calibrate the angle of the slope is calculated, and using the measured values ??of the depth or horizontal position of the probe velocity and zero calibration.
