A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum
.
In layman's terms, a vacuum pump is a device that uses various methods to generate and maintain a vacuum in a closed space
.
According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely gas capture pump and gas transmission pump
.
It is widely used in metallurgy, chemical industry, food, electronic coating and other industries
.
The function of the vacuum pump is to remove gas molecules from the vacuum chamber and reduce the gas pressure in the vacuum chamber to achieve the required vacuum degree
.
Generally speaking, there is a large range from the atmosphere to the vacuum, and so far there is no vacuum system that can cover this range
.
Therefore, in order to achieve the process indicators, work efficiency and equipment working life requirements of different products, different vacuum system configurations need to be selected for different vacuum sections
.
The quality of the vacuum pump depends on its mechanical structure and the quality of the oil.
Protect it when using the vacuum pump
.
If the volatile organic solvent is distilled, the organic solvent will be absorbed by the oil, which will increase the vapor pressure, thereby reducing the evacuation efficiency.
The turbid liquid is pumped out and the vacuum pump is damaged
.
Therefore, pay attention to the following points when using the vacuum pump: Between the distillation system and the vacuum pump, an absorption device is installed
.
Before distillation, use a water pump to remove the vapor of the organic solvent in the system
.
If you can use a water pump to pump air, try to use a water pump.
If the distillate contains volatile substances, you can first use a water pump to reduce the pressure, and then use an oil pump
.
The decompression system should be kept airtight, all rubber stoppers should be of suitable size and hole, and the rubber tube should be a rubber tube for vacuum
.
