Note automatic tank gauge systems

automatic tank gauge systems in order to ensure the correct selection level gauge to better use. Choice of what kind of instrument should be based on the level of physical and chemical properties of the test to determine the fluid medium? Make level gauge diameter, flow range, lining materials, electrode materials and output current? Can adapt measured fluid the nature and flow measurement.

Such as for trade settlement, custody transfer and energy measurement products occasions, should choose higher level of accuracy, such as 1.0, 0.5, or higher level; process control applications for select different accuracy classes according to the control requirements; some only about the process flow is detected, without making precise control and measurement of the occasion, you can choose a slightly lower level of accuracy, such as 1.5, 2.5, or 4.0, then you can choose inexpensive plug-in level gauge.
2, measurable media
Medium flow rate measurement, the instrument measuring range and caliber of the media in general, the level meter full scale flow can be measured in the medium velocity 0.5-12m / s range selection, the range is wide. Select the meter size (diameter) is not necessarily the same process piping,fuel card management system should be considered whether the measured flow rate range within the range of flow rates to determine that when the pipe flow rate is low, can not meet the requirements of the flow meter or when this flow rate measurement accuracy can not be guaranteed, the We need to narrow instrument caliber, thereby increasing the flow rate of the tube to obtain satisfactory measurements

The basic principle of automatic level gauge system

automatic tank gauge systems in the measurement circuit is energized in the first instantaneous wire waveguide to produce an electrical pulse, the electrical pulse generates a circular magnetic field around the wire in the waveguide, the role of magnetic fields within the magnetic field and the float magnet in produce a small distortion on the waveguide wire deformation, this deformation along the waveguide wire to wire two moves when moving to pickup coil,ank level gauge systemdue to the magnetostrictive effect, will send out a weak magnetic field changes, the pickup coil onYou can detect this change in the magnetic field.
Since the distortion is a constant velocity along the waveguide wire movement, therefore, issue-driven electrical impulses from the beginning to pick up a change in the magnetic field experienced by the end of the length of time, showing the position of the float from the pickup coil, also reflects the high and low level , enabling accurate measurement of the liquid level.

Level Meter System Works

With Jingyi Measuring principle

When the liquid level transmitter into the liquid to be measured to a depth meter force sensor greet liquid formula is subjected: Ρ = ρ .gH + Po
Where:
P: liquid level transmitters meet the force suffered instrument
ρ: Measuring liquid density
g: local acceleration due to gravity
Po: the atmospheric level meter
H: Transmitter into the depth of the liquid
At the same time, stainless steel instrument will be introduced by the force of the liquid gas to the positive lead instrument chamber sensors connected to the negativeautomatic tank gauge systems Po instrument chamber and the liquid level sensor and then on to the back of the sensor offset Po, the sensor instrument measured force : ρ .gH, apparently, by the measuring instrument to take force P, can be liquid depth.

What automatic tank gauge systems the role of the fuel tank level gauge

Clearly visible near the filling point must have level gauge, make filling; tank level gauge system in the front of the side wall of the tank should be provided with a level gauge to observe the oil level (the highest and lowest oil oil) ??? ① gauge should not be too long or too short. Gauge reflects tank liquid level indicating device, it should reflect the highest and lowest level of the tank unit. automatic tank gauge systems could easily lead to gauge long enough oil tank misjudgment; too short not reflect the minimum level allowed, resulting in frequent up the oil, add unnecessary maintenance work. ② gauge automatic tank gauge systems selection should consider the use of the environment. When used with a transparent multi-level gauge plastic and other materials that may appear bump, low temperature, strong vibration, etc. in the work environment, easy to gauge damage, then an additional selection of other types of level indication, such as plexiglass automatic tank gauge systems or float type level gauge sender unit, by the permanent magnets on the float makes the reed switch is turned on and the sender, where the height of the reed switch can be adjusted as needed, easy to use

Oil tanker gun will not appear out of the oil causes and solutions are there?

Tanker boot normally, but no oil gun oil, may be reverse the motor or transmission belt loose, broken. If this is the reason, then we can properly adjust power phase sequence, adjust or replace the belt tensioner wheel can be. If oil and gas separator fails, then you score following cases were analyzed:
① tanker filters (including conical strainer) is clogged serious. The filter should be cleaned to remove debris;
② oil separator valve stuck untapped oil tank calibration software caused no oil. Maintenance should remove the valve, reassembly after clearing the debris, so that it can, the next move freely;
③ small oil separator float into the oil or fall off, resulting in the formation of high-pressure high-pressure cavity can also cause no oil tank calibration method;
④ oil separator pressure pad cover damage caused by high-pressure chamber communicating with the pressure chamber, resulting in high pressure cavity do not form a high pressure leaving no oil tanker.
⑤ oil and gas man separator filter pads or spring seat damaged. Replace damaged seal.

The role of small fuel dispenser spill

For the analysis of the various parts of the small tanker, thereby enhancing the understanding of the small tanker. Introduced the case of a small tanker vane pumps and oil pumps, etc. It should be noted in a previous article. Works and analysis of fault diagnosis and now we look at the role of the relief valve in the pump its principal role.
Relief role is:
High pressure relief valve within the pump chamber of a door leading to the low pressure chamber, which is mainly from limiting the maximum pressure and protect the hydraulic system of the hydraulic system, and can regulate output retail fuel dispensers traffic.
Relief works:
When the motor is started, the oil pump, pressure oil flows from the pump pressurized area of ​​oil and gas separator and P relief valve opening time if open oil gun, pressure oil flows to oil separator, pressure relief valve is turned off, the pump The positive pressure and negative pressure zone area pass each other; when the oil gun is closed, the pressure in the hydraulic system of the rapid increase in oil pressure relief valve spring will overcome, the spool to the right, high-pressure oil through the relief valve P O ports and port flows to the pump suction area to achieve a circulating oil pump.
Increase the spring force can be increased up pressure in the hydraulic system. Without relief, when the hydraulic system pressure is higher than a certain value. System weak link in most book 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. The output portable fuel transfer pump traffic increases; when the adjusting screw counter-clockwise, the pressure required to open the relief valve is reduced, some oil through the relief valve back to the pump suction area, the external output flow decreases.

Small fuel dispenser oil pump removal and reinstallation of note:

First, install the pump cover. Copper sleeve should be coated with a little grease in order to mounting oil seal and protection. When mounting the pump cover screws, should be strictly in accordance with the order of twice the diagonal tighten each screw tightening torque knob should be basically the same, so as not to pump cover and pump combination Mifengbuyan.
Next Before disassembling the pump cover shall sanding Woodruff keyway on the shaft, so as not to dismantle the pump cover scratches on Woodruff keyway burr seal, causing leakage.
Again before the pump is mounted on the pump separator pad should be carefully examined for damage, whether to put reversed. Pump installed, should ensure that the center plane of symmetry pump pulley and motor pulley central plane of symmetry in the same plane, the pulley does not allow a clear swing and axial runout phenomenon.
At the same time the rotor assembly into the pump chamber, the application of hand (or stuck with a rigid shaft keyway hand) rotating rotor blades look carefully at whether the retractable blade slots, while viewing the rotor blade is higher. If higher rotor blades, the blades shall be polished. So that the rotor contour or slightly below the rotor.
And before servicing must be reliably cut off the power. Remove the belt from the pulley, so as to avoid accidental injury. Ready tipping the oil container to avoid oil pump and oil separator drain spilled everywhere. Finally, before you re-install the pump, use kerosene to clean all parts, do not allow any sticky dirt to avoid scratching the pump, resulting in a new fault.
Caution Disassembly and reassembly of the small auto fuel dispenser oil pump requires very close attention. The requirements of the pump seal, no leakage, the moving parts can move flexibly cable wiring, noise and vibration at work. So the various demands of the tanker is also very strict. For these considerations need more attention. After reading notes on a small heavy duty fuel dispenser oil pump is also to look at some of the latest developments on the submersible pump.

Does anyone know fuel dispenser works

Now tank automation system market is divided into electronic and mechanical tanker tanker two products. It is the most commonly used electronic tankers, is the computer type tanker, into the pump, oil and gas separation, metering, counters, motor and refueling guns. Tanker metering accuracy ± 3 ‰, usually every six months by the local metrology calibration checks,

Small fuel dispenser vane pump use and maintenance:

In a small portable fuel dispenser use, it requires frequent inspection and maintenance vane pump.
First test machine and cleaning the auto fuel dispenser, can not use water or an aqueous oil tankers, in order to avoid the cracking damage pumps and other components of internal corrosion and low temperatures.
Secondly, you should regularly clean the filter, especially a newly installed machine and piping and even more so. With the increasing use of time, dirt tank and the pipeline will be reduced, the filter cleaning cycle can be extended, but generally should not exceed one month.
Again always check whether a flexible vane pump is running even with or without abnormal noise, shaft and pump cover at the leaks, pulleys for excessive runout and wobble like.
At the same time the relief valve spring can not be adjusted too tight, or make the system pressure, noise and vibration increases and exacerbate the pump bearing wear.
Finally belt tension should be appropriate, tensioning force is too small, the belt slippery, causing supply shortage or supply, belt is also easy to wear, the tension is too large, the motor shaft and pump shaft bear additional load (axial direction of the vertical axis) increases, could easily accelerate the motor bearings, pump bearings and seals wear.

Small fuel dispenser measurement accuracy analysis:

Small retail fuel dispensers metering accuracy analysis: Small tanker meter is generally performed using a standard profile or verification, by indicating the volume of fluid metered volume indication on the counter, in the standard container is the volume of fluid injection Another volume indication appears, the difference between two values ​​is called meter absolute error of the measured volume, the relative error E its measurement accuracy is: E = (VJ-Vs) / Vs x100% wherein: VJ- metered The oil indicated value on the display panel. The actual volume measured Vs- standard containers indication. Visible small tanker still has his error exists.
From the above equation, E> 0, it means that VJ is greater than Vs, the measurement value that is greater than the standard meter display shows the value of the container, less fat oil tanker to the user. E <0, ie oil tanker multiple users, for two reasons indication error generated more complex, including the systematic errors and random errors. System errors can be compensated by appropriately adjusted. We use the adjusting mechanism adjusts the actual displacement flow meter is in compensation or correction flowmeter system error, in order to improve the accuracy of the meter. Factors affecting the measurement error problem of small tankers also have a lot of. So sometimes can not blindly suspect misconduct gas station.

fuel dispenser blade failure

Vane pump failure; if the vane pump relief valve can not be closed. Due to a foreign body (broken shrapnel, etc.) stuck in between the relief valve spool and valve seat, causing the oil inside the loop always do and can not flow in the pump, repairs should remove the valve, remove the foreign body seat; if Because the pump with the rotor blades and the shrapnel long do high-speed operation, will wear due to fatigue, fracture, leading to vent vane pump increases, even when serious loss of pumping action, the hand gasoline pump should be clear debris and repair damaged leaves, shrapnel, re-install the new replacement; and vane pump and oil separator pad bonding surface of pump breakdown or anti-loaded, can also cause the vane pump high-pressure chamber communicates with the low pressure chamber, resulting in the loss of the fuel transfer hand pump drain; if vane pump loose rotor and the rotor shaft, causing the shaft idle, this time in need of replacement repair rotor or vane pump.
