Routine Maintenance and Troubleshooting for Freezing Point Osmometers
After daily use, wipe the instrument's exterior casing with a soft, dry cloth to remove dust and stains, preventing them from entering the instrument's interior and affecting performance. For critical components such as the sample needle and stirring paddle, use specialized cleaning tools—such as a cotton swab dipped in a small amount of alcohol—to gently wipe away residual samples and impurities. This prevents clogging or corrosion and ensures measurement accuracy.In the field of petroleum refining experiments, safety and reliability are crucial. The one to two CT4 explosion-proof high and low temperature integrated machine launched by Xinzhi Afus has become an ideal choice in petroleum refining experiments due to its stable safety performance and efficient temperature control capability.
1、 Equipment Overview
2、 Security measures
- Explosion proof designThe overall equipment adopts explosion-proof design, enclosing all electrical components in explosion-proof chambers to effectively prevent danger caused by electric sparks.
- Safety interlock systemEquipped with SIL2 safety interlock system, real-time monitoring of equipment operation status. Once abnormal combustible gas concentration or temperature limit is detected, the equipment will automatically cut off the power supply to the heating and compressor, and activate the inert gas purging function.
- Explosion proof materialsKey components such as heaters, sensors, and junction boxes are made of CT4 explosion-proof materials, and the surface temperature is strictly controlled within a safe range.
- Pipeline sealingThe equipment undergoes a 48 hour nitrogen pressure test to ensure the sealing of the pipeline system and prevent any potential leakage risks.
-
Real time monitoring and alarmThe 7-inch explosion-proof touch screen displays real-time parameters such as pressure, temperature, and flow rate. In case of abnormal situations, it automatically triggers sound and light alarms and records logs to ensure timely detection and handling of problems.
