SU761426A1 - Fuel dispenser - Google Patents

Description

The invention relates to measure-. technology and can be used to refuel various vehicles.

Known fuel dispensing column consisting of a filter, a pump connected to it with an electrode · drive, a gas separator at its outlet, a volumetric fuel meter, a counting mechanism, kinematically connected to the latter, a device for introducing a density correction, including a variator located between the fuel meter , and a counting mechanism and a hose with a dispensing tap [1].

The disadvantage of this device is its low accuracy due to the inertia of the thermal sensor, indirect correction by density through temperature, the elasticity of the thermal sensor liquid, and the need to manually adjust the initial density of the liquid.

The aim of the invention is to improve the accuracy of the dose.

This goal is achieved by the fact that the device for the introduction of the correction πφ density provided

electromagnetic follower, com and actuator,

^: connected to one side with a tracking receiver, and on the other 5 with a variator, while the gas separator is equipped with a float chamber, and a float having a circuit with calibrated links and located in the area of the electromagnetic tracking receiver.

The drawing shows the proposed fuel dispenser.

The column consists of filter 1, pump 2 with electric drive 3, gas separator 4 discharged at its exit with float chamber 5, float b with chain 7 having calibrated links immersed in gas separator liquid 4,

.20 volumetric meter 8 of fuel, kinematically connected with it is a calculating mechanism 9 and a device for introducing a density correction, which includes a variator 10, an electromagnetic tracking receiver 11 and an actuator 12 connected on one side with a tracking receiver 11, and the other with variator 10 , and hose with razolochny, tap 13.

Fuel dispenser works as follows.

When the actuator 3 is turned on, the pump 2 pumps fuel through the gas separator into the fuel meter 8 and then through the hose with the dispenser,

tap 13 to the consumer's tank. Taty ³ The results of measurement are transmitted from the fuel counter 8 counting mechanism 9 through the variator 10. With the change in liquid density and it varies, the buoyancy acting on the float used which changes its position adjustment, that causes the supply signal from the tracking receiver 11 activation of actuator actuator 15

12 / "which moves the receiver 11 to align with the new position of the float b and accordingly changes the gear ratio of the variator .10, which provides a recalculation of 20

the result of measuring the volume in accordance with the actual density of the liquid. Suspended on the float 6 chain 7 with calibrated links provides linear movement 25

float b, depending on the change in the density of the liquid due to the fact that the links alternately rise from the bottom of the tank as the buoyancy force (density) of the liquid increases. thirty

The introduction of the proposed device allows to obtain a significant economic effect due to

improve the accuracy of fuel supplied to the gas station.
