Abstract

An automatic microscale carbon residue tester for petroleum products comprises an upper casing, a middle casing and a lower casing. A constant temperature bath is fixed inside the upper casing, a heater is wrapped to the outer wall of the constant temperature bath, a plurality of test tubes are disposed on a test tube rack inside the constant temperature bath, a thermal insulation cover is arranged at the top of the constant temperature bath, a temperature sensor is mounted at the bottom of the constant temperature bath, a nitrogen flow converter is mounted in the middle casing and communicated with the constant temperature bath through a gas flowmeter, a gas inlet tube and a gas inlet hole, an external nitrogen cylinder is connected to the nitrogen flow converter, an exhaust tube is arranged at the bottom of the constant temperature bath, a residue flask is arranged below the exhaust tube which is communicated with air, a control mainboard is mounted in the lower casing, and a pressure regulation knob, a nitrogen pressure gauge, a temperature controller and a power switch are mounted on a casing panel. The automatic microscale carbon residue tester has the advantages that automation level is high, time, temperature and nitrogen pressure are all controlled by programs, and the tester is simple and safe to operate and accurate in data.

Description

The automatic micro-carbon residue analyzer of a kind of petroleum products

Technical field

The utility model relates to the petroleum products detecting instrument, the automatic micro-carbon residue analyzer of promptly a kind of petroleum products.

Background technology

Traditional petroleum products trace carbon residue analyzer all is manually-operated, and efficient is low, and dangerous, the measurement result poor accuracy.

Summary of the invention

In order to overcome traditional low, dangerous, coarse shortcoming of petroleum products trace carbon residue analyzer manually-operated efficient, the utility model proposes the new design of the automatic micro-carbon residue analyzer of a kind of petroleum products.

The automatic micro-carbon residue analyzer of this petroleum products, comprise upper casing, middle casing and lower casing, it is characterized in that, in upper casing, be fixed with Constant temperature bathtub, be surrounded by well heater on the Constant temperature bathtub outer wall, Constant temperature bathtub inside is equipped with test tube rack, be placed with several test tubes on the test tube rack, oil product to be measured is housed in the test tube, insulation cover is arranged at Constant temperature bathtub top, temperature sensor is equipped with in the Constant temperature bathtub bottom, and the nitrogen flow converter is housed in middle casing, and the nitrogen flow converter passes through gas meter, draft tube, air admission hole and Constant temperature bathtub communicate, the external nitrogen cylinder of nitrogen flow converter, have gas outlet, exhaust pipe lower part that the residue cup is arranged in the Constant temperature bathtub bottom, gas outlet and atmosphere communicate, in lower casing, control main board is housed, pressure is housed on the machine shell panel regulates knob, the nitrogen pressure table, temperature controller and power switch, control main board and temperature sensor, the nitrogen flow converter, pressure is regulated knob, the nitrogen pressure table, temperature controller, power switch is electrically connected.

During use, first inflated with nitrogen 10 minutes in Constant temperature bathtub, per minute fills 600ml, be heated to 500 ℃ then, per minute inflated with nitrogen 150ml kept 15 minutes, be reduced to then below 200 ℃, take out test tube and weigh, the number percent that its residual quantity accounts for the original weight of sample is exactly the data of surveying.

The utility model has the advantages that: automaticity height, time, temperature, nitrogen pressure be by programmed control, simple to operate, safety, and data are accurate.
