The tips for using vacuum system mainly include the following aspects:
Equipment selection and preparation: When selecting vacuum system equipment, you need to consider the pumping rate, pump type (such as mechanical pump, diffusion pump, vortex pump, etc.), and whether cooling equipment, filters, vacuum gauges and other auxiliary equipment are needed. Before starting, make sure the equipment and pipelines are clean and dust-free, and check whether the seals and pipelines are intact.
Operation steps and precautions:
Start-up sequence: Start the vacuum system in the correct order according to the equipment manufacturer's guidelines. Usually, the main pump should be started first, and then the auxiliary equipment.
Pumping process: The pumping rate should be gradually increased during pumping to avoid equipment damage or explosion caused by excessive pressure difference. Always observe the reading of the vacuum gauge and adjust the pumping rate and time as needed.
Stop operation: According to the standard process at the end of the operation, gradually shut down the vacuum system to avoid equipment damage caused by sudden changes in pressure.
Application skills in different environments:
Industrial production: In the process of material handling, coating and drying, pay attention to parameters such as gas type, temperature and pressure, and select appropriate materials and equipment.
Laboratory research: When used for material analysis, characterization and preparation, ensure that laboratory conditions meet the operating requirements and avoid external interference.
Maintenance and care:
Regular inspection: Regularly check the working status of components such as vacuum pipelines, vacuum sources, vacuum accumulators, etc. to ensure their normal operation.
Cleaning and replacement: Regularly replace the filter element and filter of the mechanical pump to ensure that the equipment is in good condition. Regularly check the lubrication, bearing temperature and bearing wear of the motor bearings and other indicators.
