Abstract
The present invention discloses a determinator, which comprises a body, a controller and a cold bath, and is characterized in that a test tube is arranged inside the cold bath, the top portion of the cold bath is provided with a cold trap cover, a refrigerator is arranged outside the cold bath, the cold trap cover is provided with a gas inlet hole, the gas inlet hole is connected to an air compression pump through a gas inlet pipe, the gas inlet pipe is provided with an electromagnetic valve, and the piston of the air compression pump is connected to a stepping motor. According to the present invention, with the determinator, the pour points of the petroleum and the petroleum product can be rapidly and accurately determined.
Description
Technical field
The present invention relates to a kind of analyzer.
Background technology
Current mensuration oil and petroleum products pour point load after test tube is cooled to uniform temperature with sample, whether the sample of oil and petroleum products of detecting by an unaided eye flows to measure pour point, the method can cause artificial error very large due to the observation of naked eyes, and after higher temperature does not record pour point, the cryostat of sample being put into one by one lower temperature is repeated above-mentioned observation process until measure pour point, therefore need multiple cryostat, operate extremely loaded down with trivial details.
Summary of the invention
For solving above-mentioned existing shortcoming, fundamental purpose of the present invention is the analyzer providing a kind of practicality, can accurate Fast Measurement oil and petroleum products pour point.
For reaching above-described object, following technical scheme taked by a kind of analyzer of the present invention:
A kind of analyzer, comprise body, controller and cryostat, it is characterized in that, be provided with test tube in described cryostat, cryostat top is provided with cold-trap lid, is provided with refrigerator outside cryostat, described cold-trap covers and is provided with air admission hole, described air admission hole connects air pressure pump by draft tube, and described draft tube is provided with solenoid valve, and the piston of described air pressure pump connects stepper motor.
Described cold-trap covers and is provided with snorkel, and in described snorkel, test tube is stretched on top, and snorkel connects pressure transducer, and snorkel is other is provided with solenoid valve, and in snorkel, top is provided with a temperature sensor.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Can accurate Fast Measurement oil and petroleum products pour point.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of analyzer of the present invention, comprise controller 1 and cryostat 2, test tube 3 is had in cryostat 2, cold-trap lid 4 is arranged at cryostat 2 top, semiconductor cooler 5 is had outside cryostat 2, cold-trap lid 4 has air admission hole 6, air admission hole 6 connects air pressure pump 8 by draft tube 7, and in draft tube 7, side is connected to solenoid valve 9, the piston 10 of air pressure pump 8 connects stepper motor 11, cold-trap lid 4 has snorkel 12, in snorkel 12, test tube 3 is stretched on top, and snorkel 12 connects pressure transducer 13, snorkel 12 is other connects solenoid valve 14, and in snorkel 12, there is a temperature sensor 15 on top.Sample is contained in test tube 3, semiconductor cooler 5 starts cooling, according to the pressure of setting, the revolution of control step motor 11 promotes the piston 10 of air pressure pump 8, stall to setting number also postpones 5 seconds, air pressure passes in cryostat 2 through draft tube 7 by air admission hole 6, put on the test product in test tube 3, if test product not yet freezes, by snorkel 12, pressure transducer 13 detects that pressure changes, test product liquid level rises, stepper motor 11 reverses and resets, solenoid valve 9, 14 open, once often declining with temperature, repeat said process, until test product freezes, the temperature that temperature sensor 15 now detects is condensation point, condensation point temperature is added the pour point being once test product.
