Description
Technical field
The utility model relates to the dispensing apparatus of oil product, particularly a kind ofly is used for the system that the quantitative shipment of hair oil is carried out to oil carrier in harbour, harbour etc.
Background technology
At present, in the oil product ship-loading operation of harbour water route, be mainly manual operations, operating personal detects the oil temperature, according to the cooresponding density of oil temperature the hair oil amount is scaled volume, then through FL/MTR control hair oil.In the hair oil process, operating personal need be paid close attention to the number of walking of FL/MTR, when FL/MTR is walked the oil product total amount that number adds near the need of oil carrier, closes minor valve in advance, when reaching total amount, valve is closed fully.This kind hair oil mode, operating personal are difficult to hold accurately the lead and the shut of closing valve, and the error that oil product is provided is big, precision is low.Simultaneously, because the charge of oil capacity of oil carrier is very big, for the oil carrier of hundreds of ton, last kiloton; The ship-loading operation of its oil product is chronic, needs tens even reach tens hours usually, during whole hair oil; The temperature of oil product has greatly changed with the variation of temperature sometimes; Can there be bigger calculation error in the hair oil volume that only adopts hair oil before measurement gauging temperature to convert, influences the precision of hair oil.In order to reduce influence of temperature variation, can in the hair oil process, increase measurement to temperature, after each the measurement, recomputate the hair oil volume is done adaptive correction, to reduce the influence of temperature the hair oil precision.Yet even the thermometric number of times of artificial increase, it still only can partly reduce error, and is still not ideal enough to the control of hair oil precision; And it has also increased the measurements and calculations work of operating personal significantly.
In addition, above-mentioned existing method is in whole hair oil operation; The reading of temperature, the calculating of hair oil amount, the control of oil product flow velocity; And closing through manual work of valve carry out, and it thinks that the factor that gets involved is many, and the precision of hair oil receives artificial factor big; Operating personal is made mistakes in any one link, all may give birth to bigger influence to the hair oil volume production.In addition,, also there is bigger security risk through above-mentioned manual operation hair oil, untimely because of closing valve easily, and emit the cabin accident, cause water pollution.And high-volume the time, monitoring management is difficulty comparatively wholesale, gives easily and steals oil, the stolen molecule leaves opportunity, causes administrative vulnerability.
Summary of the invention
Being intended to of the utility model provide a kind of simple to operate, the hair oil precision high, and the quantitative ship-loading system of oil product of safety and environmental protection more.
The quantitative ship-loading system of the described oil product of the utility model; Comprise the hair oil pipeline that connects oil vessel; The end of hair oil pipeline is connected with oil transfer arm; The center is equipped with oil pump and volumetric displacement meter, it is characterized in that: the hair oil pipeline is equipped with electric gate valve before oil transfer arm, and temperature transmitter, pressure transformer, densimeter are installed between FL/MTR and electric gate valve; The quantitative ship-loading system of said oil product also comprises the PLC controller; The PLC controller links to each other with volumetric displacement meter, densimeter, temperature transmitter and each pressure transformer, can read the take off data of volumetric displacement meter, densimeter, temperature transmitter and each pressure transformer in real time, simultaneously; The PLC controller also links to each other with oil pump through frequency converter; Can be through the start and stop and the rotating speed of Frequency Converter Control oil pump, the PLC controller also connects electric gate valve, the switching of may command electric gate valve.
The quantitative ship-loading system of the described oil product of the utility model to mounting temperature transmitter, pressure transformer, densimeter between the control cock, can be gathered temperature, density and the line pressure of oil product at FL/MTR in real time; And send the data of gathering to the PLC controller; The PLC controller calculates the hair oil amount in real time according to temperature, density and the pressure gathered, when the hair oil amount of the numerical value of volumetric displacement meter and calculating is consistent; The control electric gate valve is closed, and finishes hair oil.The control of its whole hair oil amount is accomplished through system automatically, and is simple, convenient, do not receive artificial factor, and control accuracy is high.And in its hair oil process, the PLC controller can be revised the hair oil amount according to temperature traverse in real time, can solve the influence of temperature traverse to the hair oil precision fully, and the hair oil precision is high.Simultaneously, when its hair oil finished, the PLC controller can control electric gate valve at once and cut out, and in time closes valve, cut off oil circuit, can avoid the generation of bleed accident, thereby also safer, environmental protection.
Said hair oil pipeline is equipped with scalable and opens and closes the degree electric control valve between electric gate valve and oil pump; Electric control valve is connected with the PLC controller; Through the switching degree of PLC controller may command electric control valve, thus can be through the flow of motorized adjustment valve regulation hair oil pipeline.The numerical value that reads volumetric displacement meter as PLC is during near the hair oil amount; Be before hair oil closes to an end, the PLC controller can be controlled electric control valve earlier and progressively turn down before the control electric gate valve is closed; Thereby reduce the postal materials flow in the hair oil pipeline, to accomplish accuracy control to the hair oil amount.
Said, the PLC controller also can link to each other with oil pump through frequency converter, through the start and stop and the rotating speed of Frequency Converter Control oil pump.When needs increase pipeline flow, can increase through the Frequency Converter Control pump speed; , during flow, can reduce by needs in reducing pipeline through the Frequency Converter Control pump speed.
Said hair oil pipeline can be at the import and export setting pressure transmitter of oil pump, and connects two pressure transformers through the PLC controller.Through at oil pump inlet and outlet piping setting pressure transmitter, the PLC controller can be monitored the pressure at oil pump two ends, thereby the rotating speed of control oil pump adapts to the requirement of pressure; The rotating speed of control oil pump adapts to the aperture requirement of electric control valve; Perhaps when pressure anomaly, report to the police.
Description of drawings
Fig. 1 is the scheme drawing of the quantitative ship-loading system of the described oil product of the utility model.
The specific embodiment
The quantitative ship-loading system of a kind of oil product; Like Fig. 1; Comprise the hair oil pipeline 1 that connects oil vessel 20, the end of hair oil pipeline is connected with oil transfer arm 2, and the center is equipped with oil pump 3 and volumetric displacement meter 4; Said hair oil pipeline is equipped with electric gate valve 5 before oil transfer arm, temperature transmitter 6, pressure transformer 7, densimeter 8 are installed between FL/MTR and electric gate valve; The quantitative ship-loading system of said oil product also comprises PLC controller 9; The PLC controller links to each other with volumetric displacement meter, densimeter, temperature transmitter and each pressure transformer, can read the take off data of volumetric displacement meter, densimeter, temperature transmitter and each pressure transformer in real time, simultaneously; The PLC controller also links to each other with oil pump through frequency converter 10; Can be through the start and stop and the rotating speed of Frequency Converter Control oil pump, the PLC controller also connects electric gate valve 5, the switching of may command electric gate valve.
