The temperature range of vacuum system is usually between -163℃ and 100℃, depending on the type of vacuum system and application scenario. For example, the temperature range of no-load vacuum is -163℃ to 100℃.
Performance of vacuum system at different temperatures:
Low temperature environment: In low temperature environment, different types of vacuum pumps may encounter problems such as poor lubrication, excessive starting current, and bearing damage. For example, starting an oil vane pump in an environment below 5 degrees Celsius may cause excessive starting current or even burnout of the motor, tearing and damage to the shaft seal, etc.
High temperature environment: High temperature may cause excessive wear of the internal components of the pump, reduce efficiency, and even cause safety accidents. Therefore, it is very important to maintain the vacuum pump within a reasonable operating temperature range.
Maintenance measures for vacuum system at different temperatures:
Low temperature environment: For vacuum equipment used in low temperature environment, the following measures can be taken:
Oil vane pump: When starting at 5-10 degrees Celsius, you can use the inching method to energize it several times before letting it run continuously to avoid direct starting in an environment below 5 degrees Celsius.
Roots pump, screw pump: At low temperatures, the oil is relatively viscous. Forced starting will cause faults such as excessive motor starting current and shaft seal tearing and damage. Heating measures need to be taken and soft starting is best.
Molecular pump: At low temperatures, the lubricating oil or lubricant has a high viscosity, which may cause poor bearing lubrication and excessive molecular pump starting current. Certain heating measures need to be taken, and soft starting is best.
High temperature environment: Regularly check and clean the filter, ensure good ventilation, regularly replace high-quality lubricating oil, and contact professional technicians for inspection and maintenance when necessary.
