vacuum pump working principle


It is important to understand the function of the vacuum pump when designing or operating the vacuum system. We will review the working principles of the most common vacuum pumps and their use in the system. Over the next few months, we’ll look at each of these pumps in more detail.
Pump type (according to work pressure)
The vacuum pump is classified according to the working pressure range, mainly divided into: main pump, booster pump or secondary pump. Within each pressure range, there are several types of pumps, each with different techniques, each with unique advantages in terms of pressure capacity, flow, cost and maintenance requirements.
Regardless of its design, the basic principle of operation is the same. The vacuum pump works by removing air and other gases from the vacuum chamber (or, if connected, from the outlet side of the higher vacuum pump). When the pressure in the chamber is reduced, removing other molecules becomes difficult to remove. Therefore, the industrial vacuum system (figure 1) must be able to operate within a particularly large pressure range, usually from 1 to 106. Applications in scientific research can be extended to 109 or lower. In order to achieve this, several different types of pumps are used in a typical system, each of which covers a part of the pressure range and is sometimes connected in series.

DIY Vacuum Pump And Chamber


How to make a simple but effective vacuum chamber with a fridge compressor and a steel pot. Very inexpensive if you can find these few components used!
A vacuum chamber is needed for some other projects that I’ll do in the future like degassing resin, plaster, silicon and wax or stabilizing wood! Be sure to subscribe if you are new to the channel and turn notifications on so you won’t miss upcoming video.
Index of operation and materials:
0:03 fridge compressor
0:19 Steel pot 27cm diameter, nice thick walls
0:21 Specific high strenght polycarbonate 10mm (better use thicker like 20mm for regular polycarbonate or plexiglass)
0:32 Gas rated tubing with thick walls secured with steel hose clamp
1:10 Finding, center punching and drilling hole
1:31 Threading for 1/4 inch pipe thread connector
2:00 Various 1/2 inch pipe connection. Doesn’t matter size get cheapest, I’m pretty sure any measure would work just fine
2:02 Vacuum gauge bought on amazon: https://amzn.to/2Olh55T (affiliate link) with 1/4inch female to 1/2inch male adaptor
2:10 Assemble everything with teflon tape and \”Hand Tool Rescue\” wrench
4:09 Connect other end of the compressor pump to the valve assembly again with steel hose clamp
4:12 Sealing the edge of the pot with car door rubber trim (used to prevent damage to edge of car’s doors)
5:00 leak between seal parts filled with silicone
5:50 rewiring pump power cable and adding a power switch to one of the live wire to make it easier turning on and off the pump
8:05 Thick MDF board used as base
8:42 Rubber feet added to the bottom side of the base
With my particular compressor I’m able to pull 27.5 inHg.
The ball valve between the chamber and the compressor was not needed at the end, the compressor must have some kind of one way valve so even when it’s turned off it does not let air in.

Thanks a lot for watching, I hope you liked the video!
