Description
Measuring complex of the top dosed filling low - viscous nonaggressive liquids with the commercial account in volume and mass units, ASN – 10VG the Du100 4/4 module with volume counters or mass flowmeters of Coriolis type, with pumps for the land or buried tanks, with entrance ladders and cross over ladders, on two compartments of two tanker trucks from each party of a bulk island.
-
Metrology:
Application of the complex measuring scheme consisting of the pump, a flowmeter of the valve of the splitter and the operating controller allows to achieve the maximum accuracy at the dosed holiday of oil products in tanker trucks with an accuracy of 0,15% on volume and 0,25% on weight. Adjustment of an expense is carried out in the program way and allows to make control of an expense for the concrete technological pipeline of an object, taking into account height of a vzliv in the tank and to minimize hydroblows that increases dispensing accuracy.
-
Metrological functions of the equipment:
- control of a dose of the released product on the controller of management on a filling post -
- the accounting of the released dose in units of mass, the actual volume and volume specified to the set temperature (ON "an automated workplace of the Operator of filling discharge") -
- dose task from operator -
- continuation of a holiday of the set dose at elimination of accident with the permission of the operator from PDU or the computer -
- display of information on total amount of the released fuel on a call of the operator to PDU or at submission of the corresponding command from the computer -
- high precision of dispensing and protection against hydroblow.
-
Safety:
Measuring complexes are made according to requirements of industrial safety and ensure the maximum safety at operations of discharge filling of oil products.
-
The following decisions are applied to safety of filling:
- entrance ladders are made with an angle of lead of 45 °C safe hand - rail, an otbortovka on all perimeter of a ladder. The design of steps prevents sliding -
- the rubbing couples of ladder, and also the knots adjoining to a car tanks are made of the materials preventing sparking -
- steps of a cross over ladder always remain in horizontal position that ensures the maximum convenience and safety at rise on a tanker truck -
- hand - rail of safety of a ladder protect the operator from falling -
- the device of grounding of tanker trucks does not grant permission for filling a product at incomplete grounding -
- the device of grounding of tanker trucks has function of recognition of a tanker truck from the grounded metal construction -
- restriction of speed of filling during the initial and final stage of filling according to rules of the state standards is provided (in order to avoid emergence to become. electricity) -
-
The complex is equipped with the sensors providing the automatic termination of filling:
- at achievement of the set dose -
- at operation of the sensor of restriction of level -
- in 20 sec. after the termination of a stream from a flowmeter -
- at grounding violation (the complex is equipped with the device of grounding of tanker trucks) -
- at operation of the sensor of garage provision of a tip -
- at operation of the sensor of garage provision of a ladder -
- at manual shutdown of the pump -
- at shutdown of process of filling by the operator from a filling post -
- at shutdown of process of filling by the operator from the STOP button on a bulk tip -
- remotely from PDU or the computer located in operator in the automatic mode or the operator at an emergency according to technological regulations -
- when receiving a signal from gas contamination sensors -
- at operation of the sensor of existence of a product in the gas separator filter that testifies to lack of a product in the filter or a large amount of air in it.
-
For ensuring safe and eco - friendly filling in tanker trucks, and also guaranteed delivery it is necessary to equip them with the special equipment: for example hatch covers with the situation sensor, the equipment for the lower filling, the socket of the lower filling, a set of sensors and the operating controller.
-
Automation:
- the limit sensor in a tanker truck -
- the STOP button for an emergency stop of filling -
- the sensor of garage provision of a bulk sleeve -
- the sensor of existence of a product in federal state institution -
- the START - UP/FEET button on a filling post -
- the sensor of garage provision of a cross over ladder -
- the button of an emergency stop -
- flowmeter (mass or volume) -
- the thermal sensor (at installation of a mass flowmeter the thermal sensor built - in) -
- the grounding device with a possibility of recognition of the tank from a metal construction -
- the adjusting valve the splitter operated with the alarm system of electro - situation -
- power case with a possibility of management of ASN, the pump with controlled sensors and also control of additional service devices (sensors of a gas contamination, the fire alarm system, access terminals, etc. ) -
- information communication from the central control unit (CCU) of the filling located on a post in operator the RS - 485 interface the Modbus RTU - protocol
- ON "an automated workplace of the operator of filling discharge" it is possible to enter into structure of SCADA of systems -
- permission of filling (a nalivshchik from operator) -
- display of parameters of process of filling for visual control by the driver or the operator of filling on the controller of management on a filling post -
- preservation in the otschyotny device of information on total amount of the released fuel and lack of a possibility of its change within 10 years at shutdown of power supply -
- local management of filling process.
-
Environmental friendliness:
Tightness of joining of ASN with a tanker truck is provided with use of covers of compartments of a tanker truck with the unified sizes of a jellied mouth and the condensing cover of a bulk tip. Withdrawal of PVS from a filling zone when filling a tanker truck through a special sleeve "on a candle" or to installation to installation of recovery of vapors is provided.
-
Additional functions (by the additional order by delivery of sensors of a gas contamination):
- the sensor of a gas contamination provides information output on the operating controller with formation of the alarm system -
- the light - sound alarm system GAZ on the ASN platform precautionary - 10% of NKPR and preemergency - 20% of NKPR -
- the signal from the sensor of a gas contamination is transmitted to a power case of ASN for a possibility of the termination of filling at a gas contamination of 20% of NKPR.
-
Reliability:
Reliable controlled giving of a product. Tightness of hinged connections. Protection against corrosion and safety of appearance is reached by application of the following methods: zinc covering in the hot way, bead - blasting processing and covering two - component enamel.
