Common Vacuum Pump Schematic Symbols
In mechanical and electrical schematics, vacuum pumps are often represented by specific symbols to indicate their function and operation. These symbols provide a concise visual representation of the vacuum pump and help engineers and technicians easily identify and understand its role within a system. Here are some common vacuum pump schematic symbols:
1. Single-stage Vacuum Pump Symbol:
The single-stage vacuum pump symbol typically consists of a circle with a horizontal line passing through the center. This symbol represents a basic vacuum pump with a single stage, where air or gas is evacuated through a single impeller or rotor.
2. Multi-stage Vacuum Pump Symbol:
The multi-stage vacuum pump symbol is similar to the single-stage symbol but with additional horizontal lines passing through the circle. These horizontal lines indicate the presence of multiple stages or impellers in the vacuum pump, allowing for higher vacuum level achieved.
3. Rotary Vane Vacuum Pump Symbol:
A rotary vane vacuum pump symbol looks like the single-stage vacuum pump symbol but with additional curved lines within the circle. These curved lines represent the vanes or blades inside the pump that rotate and create a vacuum by sealing off chambers and creating suction.
4. Diaphragm Vacuum Pump Symbol:
The diaphragm vacuum pump symbol is represented by a circle with a vertical line passing through the center and a curved horizontal line attached to it. This symbol depicts the diaphragm within the pump that moves up and down, creating a vacuum by compressing and expanding the working fluid.
5. Scroll Vacuum Pump Symbol:
A scroll vacuum pump symbol consists of two spiraling lines within a circle, with one line slightly offset from the other. This symbol represents a scroll vacuum pump where two scrolls or spirals within the pump create suction and evacuate the air or gas.
These are just a few examples of the common vacuum pump schematic symbols used in mechanical and electrical drawings. It is important to note that different industries and organizations may have variations or additional symbols specific to their applications. Therefore, it is always necessary to refer to the symbol key or legend provided in the schematic to ensure accurate interpretation and understanding.
