We all know that the imported vacuum pump oil must be much more expensive than the domestic vacuum pump oil. How can we choose a good domestic vacuum pump oil to replace the imported vacuum pump oil, so as to save the cost? If we can reasonably choose the vacuum pump oil, it will affect the starting, limiting partial pressure, power consumption, limiting total pressure, pump temperature, anti emulsifying performance, stability and reliability of pump performance And so on. In general, the selection of a good vacuum pump oil can improve the comprehensive performance index of the vacuum pump, so as to bring greater benefits to customers and produce good corporate benefits.
How to select the appropriate domestic vacuum pump oil? This can be reasonably selected according to the actual situation
1. If the pump temperature is high and the pump limit full pressure is not high, the qualified viscosity oil or mechanical oil with the same or slightly higher viscosity can be selected with lower price,
2. If the pump works at higher pump temperature for a long time, such as in hot summer and environment with heat source and poor ventilation or high inlet pressure, the high-quality oil with a higher viscosity grade or the pump oil with high temperature and high load can be used.
3. If the oil change period is short or can meet the performance requirements, the qualified oil with the same viscosity or slightly higher viscosity can be selected to reduce the oil change cost.
4. If it is difficult to start in cold weather, a lower viscosity grade of pump oil can be selected.
