1. Match the Ultimate Pressure with Production Process Requirements
The ultimate vacuum pressure of the pump must fully meet the actual working pressure required by the production process. In principle, the ultimate pressure of the selected vacuum pump should be one order of magnitude higher than the process requirement to ensure stable vacuum performance. Each type of vacuum pump has a fixed allowable working pressure range. The pump must operate within the standard working range and cannot run for a long time beyond the rated pressure limit. Under normal working conditions, the vacuum pump must completely and effectively discharge all gas generated during the operation of vacuum mixing equipment.
2. Adopt Combined Vacuum Pump Unit for Complex Vacuum Demand
In some cases, a single vacuum pump cannot satisfy high-standard pumping speed and vacuum degree requirements. It is necessary to adopt a combined vacuum pump unit to complement performance advantages. Certain vacuum pumps cannot start directly under atmospheric pressure and require pre-vacuum assistance; some models have limited exhaust pressure and need a fore pump to support stable operation.
A scientifically matched vacuum pump unit can significantly improve the overall vacuum degree, exhaust efficiency and operational stability of the vacuum system. Manufacturers should select combined solutions according to actual gas volume and process standards, as different pumps have different adaptability to exhausted gas types.
3. Select Oil-type or Oil-free Pump According to Cleanliness Requirements
Factory cleanliness standards are the key basis for pump selection. If the production process requires an oil-free clean vacuum environment (such as cosmetics, food, and pharmaceutical production), manufacturers must choose oil-free vacuum equipment, including water ring vacuum pumps and cryogenic vacuum pumps.
If the process allows conventional oil-sealed vacuum pumps, auxiliary anti-pollution accessories can be installed, such as cold traps, oil traps and baffles. These supporting devices can effectively block oil vapor pollution and achieve a clean vacuum production environment at a lower cost.
4. Select Pump Model Based on Gas Chemical Properties
Before selection, it is necessary to fully analyze the chemical composition of the gas generated during production, including condensable steam, floating particle dust, corrosive gas and irritant substances. Different gas components require targeted vacuum pump configuration.
If the exhausted gas contains steam, particulate impurities or corrosive media, auxiliary pretreatment equipment must be installed on the pump inlet pipeline, such as condensers and dust collectors. This effectively protects the vacuum pump core, avoids corrosion and clogging, and extends the service life of the mixing machine vacuum system.
5. Consider Environmental Pollution and Vibration Impact
When configuring an oil-sealed vacuum pump, it is necessary to evaluate the impact of oil vapor exhaust on the workshop environment. For pollution-free production workshops, oil-free vacuum pumps are the priority choice, or the oil vapor exhaust pipeline can be diverted outdoors.
In addition, the operating vibration of the vacuum pump should not interfere with the production process and workshop environment. For high-precision production scenarios, low-vibration vacuum pumps or professional anti-vibration measures are required to ensure stable and consistent product quality.
