Petroleum product moisture tester

Petroleum product moisture testerAccording to the standards of the People's Republic of ChinaGB/ T260Designed and manufactured in accordance with the requirements specified in the "Method for Determination of Moisture in Petroleum Products", in compliance withG/JBJD6《Petroleum product moisture testerThe requirements of "Technical Conditions". This instrument is suitable for pressingGB/T260The standard test method for determining the moisture content in petroleum products is also applicable toGB/T512The standard for determining the moisture content of lubricating grease specifies the test method for determining the moisture content in lubricating grease.

Main technical indicators
1Working power supply:AC 220V±10%，50Hz.
2Heating power of electric furnace:300W.
3Heating control: Bidirectional thyristor stepless voltage regulation control.
4Environmental temperature:≤35℃.
5Relative humidity:≤85%.
6Power consumption of the whole machine: not greater than310W.

（2） Electrical principles
The circuit mainly consists of a heating sleeve and a heating sleeve power adjustment control circuit.
The power of the heating sleeve is250WThe bidirectional thyristor is used to form an AC voltage regulating circuit, which is used to adjust the heating power of the heating jacket. The working voltage of the heating jacket is displayed by the voltmeter on the instrument panel. The heating power of the heating sleeve can be infinitely adjusted from small to large, and the magnitude of the power is intuitively displayed by the voltage value displayed on the voltmeter.
（3） Main features
1、Petroleum product moisture testerThe use of a heating sleeve as the heating element is characterized by no open flame, safe operation, and high heating efficiency.
2The heating power can be infinitely adjusted from small to large through the adjustment knob on the panel, and the distillation speed control is convenient.

Use of instruments
1, UsePetroleum product moisture testerBefore use, carefully read the user manual.
2Carefully read the standards of the People's Republic of ChinaGB/ T260Understand and be familiar with the testing methods, procedures, and requirements outlined in the standard for determining the moisture content of petroleum products.
3According to the requirements specified in the standard, prepare various testing instruments, materials, etc. for the experiment, clean and dry all glassware and instruments.
4Check the working status of this instrument to ensure it meets the working environment and conditions specified in the manual.
5Check the casing of this instrument, which must be in a good grounding state, and the external power supply must have a good grounding terminal.
6Connect the power supply, and the control panel voltmeter will display an indication. According to the experimental requirements, adjust the heating adjustment knob clockwise. The voltage value displayed on the voltmeter will increase accordingly, and the temperature of the heating jacket will rise. Select the appropriate voltage and control the distillation speed.
7When measuring, follow theGB/ T260The requirement is to mix and distill the petroleum product sample with anhydrous solvent and calculate its moisture content, expressed as a percentage.
8After the experiment is completed, the power should be turned off promptly. When the instrument is not used for a long time, it should be placed in a ventilated, dry, and non corrosive gas environment.
Warning: When the instrument malfunctions, the power should be cut off in a timely manner and professional technicians should be hired for maintenance. Only after troubleshooting can it continue to be used to prevent accidents!
