Abstract
The utility model relates to a fully automatic detector for measuring gasoline oxide stability. The running of the complete machine is controlled by an industrial computer and relevant software, and a metal bath is used for replacing a water bath or an oil bath. A ball valve is additionally arranged on an oxygen bomb. Thus, the accuracy of the detector for measuring gasoline oxide stability is raised, instrumental functions are added; in the process of measurement, instruments have the advantages of uniform temperature, convenient operation, and no noise and air pollution; the abrasion and the gas leakage phenomenon of a needle valve are eliminated. The fully automatic detector for measuring gasoline oxide stability is an ideal detector for measuring gasoline oxide stability.
Description
The utility model relates to a kind of full-automatic oxidation stability of gasoline analyzer.
Existing oxidation stability of gasoline analyzer generally is divided into record tabular form and two kinds of forms of Single-chip Controlling.Water-bath or oil bath are all adopted in its heating bath.Because in the instrument operational process, requiring the heating bath test temperature is 100 ℃.If use water-bath, water wherein then reduce because of constantly evaporating.In time additional for keeping water level just to need, but the coolant-temperature gage that replenishes into is lower, and temperature descends thereupon in not only bathing, and causes non-uniform temperature, influences test findings.If the use oil bath and since mostly with glycerine or other mineral oil as heating medium, then pollute working environment, and human body worked the mischief because of high temperature evaporation produces the oil gas mist, before and after the test cleaning of test oxygen bomb is also wasted time and energy very much simultaneously.
No matter adopt water-bath or oil bath,, must stir for making the interior temperature of bath even.Stirring motor is under the hot environment for a long time works, and often burns out easily.
In addition, record tabular form instrument is because registration accuracy not high (5Kpa/ lattice) is unsuitable for the judgement of GB/T8018-87 standard to the test flex point.
Though monolithic processor controlled instrument can be judged the test flex point automatically, can not show process of the test.The experimenter can not in time understand the data of current a certain section process of the test.
Oxygen bomb on the existing oxidation stability of gasoline analyzer all uses needle valve to control oxygen flow.Owing to need repeatedly switch to regulate the amount of oxygen size in the process of the test, so needle point very easily weares and teares, reveal thereby produce, cause test findings inaccurate.
The purpose of this utility model is to overcome the above-mentioned drawback of existing oxidation stability of gasoline analyzer, provides a kind of degree of accuracy height, function many, easy to operate, automatically, water or oil are not made the oxidation stability of gasoline analyzer that medium, oxygen bomb valve are difficult for leakage.
Technical solution of the present utility model is to adopt industrial computer and the operation of corresponding software control instrument, replaces water-bath or oil bath with metal bath, and install ball valve additional on oxygen bomb, by ball valve and solenoid control oxygen flow.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model electrical schematic diagram;
Accompanying drawing 3 is the utility model corresponding software program flow diagram.
Now set forth embodiment of the present utility model in conjunction with the accompanying drawings: adopt industrial computer and corresponding software
(1) power turn-on switch, digital display temperature controller and industrial control computer are started working, the 5V of industrial computer, 0 closing of contact, the digital display temperature controller reaches the purpose of control heating bath temperature by the break-make of control solid-state relay.Power supply and amplifier part are amplified pressure transducer 1 and pressure transducer 2 detected signals, send industrial control computer to the detected signal of temperature sensor then, carry out A/D conversion, photoelectricity isolation, linearization process in industrial computer inside, calculate, judge through industrial computer again, draw test findings, be stored in the industrial computer.After off-test, the printer switch that closes printablely goes out test findings.Charging and discharging air cock controls respectively and charges and discharge the pneumoelectric magnet valve.During off-test, the 5V of industrial computer, 0 contact disconnect, and have cut off the control loop of digital display temperature controller to solid-state relay, reach the purpose of automatic pass heating.Its corresponding software program comprises main working interface of demonstration and menu: parameter input, parameter setting, result queries, hour hands setting, screen protection, numerical value correction and flex point are judged subroutine, thus the operation of control complete machine.Printer (2) is printed trial curve data and result automatically.Metal bath (9) adopts aluminium alloy to make, and its physical dimension is long 300mm, wide 260mm, high 260mm.Heating element (10) is close to a side of metal bath (9) metal bath (9) is heated, and heating schedule is by industrial computer and corresponding software (1) control operation.Install ball valve (3) on the oxygen bomb (11) additional, joint (4), (5) are plugged on oxygen bomb joint (12) and the external welding bottle with the connection of PV pipe respectively, transmit oxygen and oxygen bomb (11) internal pressure respectively through three-way connection (6), solenoid valve (8) control oxygen bomb (11) fills automatically, exits.Precision pressure gauge (7) is connected with three-way connection (6), is used for the pressure precision of verification industrial computer and corresponding software (1) control.
The utility model has the advantages that: 1, measure precision by the 5Kpa/ lattice, bring up to 0.1Kpa, Its function comprises automatic judgement flex point, and automatic alarm requires selection multiple aobvious according to the operator is different Show mode, can press different proportion and the time interval and print curve data and result, can according to the date, Oil sample number, oil tank number, operator number inquiry result of the test in the past, show current process of the test Data, the complete automatic shutdown of mensuration work. 2, heating bath need not stirred after using metal bath instead, Temperature is even, noiselessness, no air pollution. 3, eliminated needle valve after installing ball valve on the oxygen bomb additional The wearing and tearing that produce and gas leakage drawback.
Claims (2)
1, a kind of full-automatic oxidation stability of gasoline analyzer, comprise ball valve (3), heating element (10), precision pressure gauge (7), joint (4), (5), oxygen bomb (11), three-way connection (6), oxygen bomb joint (12), solenoid valve (8) constitute, and it is characterized in that heating bath adopts metal bath (9) to accept heating element (10) heating.Oxygen bomb installs ball valve additional on (12), with ball valve (3) and solenoid valve (8) control.By industrial computer and the operation of corresponding software (1) control complete machine.
2, a kind of full-automatic oxidation stability of gasoline analyzer according to claim 1 is characterized in that metal bath (9) adopts aluminium alloy to make.
