Description

/ Co, MULTI-FUEL FILLING COMPLEX the invention relates to systems for oil products depletion at gas stations

stations and is intended for refueling through a multi-fuel refueling complex.

All known fuel dispensing systems are columns separated by fuel type. Even if the gas stations contain a lot of pistols, then anyway, each of them delivers fuel from separate fuel tanks through separate pump systems for each type of fuel. As a result, the cost of installing a refueling complex is high and is determined by the inclusion of several pumping systems and several columns for each type of fuel separately, or multi-profile columns with several guns, the fuel supply to which must be equipped in addition, which entails new costs for ensuring fire safety.

The closest to the claimed technical essence is a fuel dispenser (utility model No. 20758 of the Russian Federation B67D5 / 00), in which an information block is located on a fuel island and connected to a dispensing tap to form an information-filling block, and a pump and measuring block is installed between the information refueling unit and reservoir away from the refueling island.

This design can be implemented as a fuel refueling complex. However, its implementation only partially leads to lower costs for the installation of a gas station. And still you will have to install as many gas stations as there are types of fuel. As a result, there will be no significant gain in reducing costs.

The purpose of the proposed model is to reduce the cost of installing a gas station, by reducing the required number of fuel dispensers, which will also improve service conditions that provide a wider choice of fuel when refueling.

This goal is achieved by the fact that the column is a multi-fuel refueling complex consisting of pump and measuring units of two to eight (A1-A8), depending on the type of fuel delivered, and installed separately on the refueling island, one information refueling unit .

a drive motor (3), a fine filter in one housing with a gas separator (4), a float chamber (5), a check valve (6), a double-acting valve (7), a volume meter (8), a fuel consumption sensor with a mechanical totalizer ( 9).

The refueling unit consists of pipelines (10), flexible pressure hoses (11), gas discharge indicators (12), dispensing taps (13), controller (14), 2 digital information displays (15).

A multi-fuel refueling complex operates as follows.

After ordering fuel by the consumer, the gas station operator, through the control panel, turns on the pump measuring unit corresponding to the ordered type of fuel and the column side.

When the pump is operating at the inlet of the unit, a vacuum is created and, fuel from the tank through the inlet valve and the coarse filter (1), enters the pump (2) from which it is supplied under pressure to the gas separator. The pump has an adjustable bypass valve for passing fuel with the dispensing gun closed. In the gas separator (4), fuel passes through a fine filter. From the top of the gas separator, the vapors and part of the fuel enter the float chamber through the vent pipe. In the float chamber (5), the fuel settles and, having reached a certain level, opens the float valve and enters the input of the fine filter. Vapors of fuel and air through the hole in the cover of the float chamber exit into the atmosphere. When the float chamber overflows, the float locks its entrance. The fuel cleared of vapors and air leaving the gas separator by its own pressure opens the check valve (6) and enters the double-acting valve. The non-return valve, when the pump is stopped, prevents the flow of fuel through the float chamber into the atmosphere. The double-acting valve (7) provides the opening of the fuel supply line in full consumption mode, the partial closure of the line in the reduced flow mode and the closing of the line when the specified dose is issued. From the double-acting valve, fuel enters the piston volume meter (8). The pistons of the volume meter, under the influence of the passing fuel, drive the meter shaft, which is connected to the fuel consumption sensor (9). The flow sensor generates a signal proportional to the number and angle of rotation of the meter shaft. The signal from the sensor is transmitted via cable to the controller (14) located in the information-filling unit. The sensor shaft is connected by a flexible coupling to a mechanical totalizer.

Fuel from the volume meter through the pipeline laid through the territory of the gas station enters the inlet located separately of the information-filling unit and through its own pipelines of the block (10), pressure hoses (11), through the exhaust gas indicators (12) and the dispensing taps (13) into the consumer tank. The controller (14) processes the signals from the fuel flow sensors of the pump

blocks, and issues its control signals to the corresponding digital information board (15). The controller processes the information for each pump and measuring unit separately.

Such a design and operation of a multi-tearing zavrachnogo complex allows you to reduce the cost of installing a gas station, by reducing the required number of fuel dispensers, and also improves service conditions that provide a wider choice of fuel when refueling.
