When shopping for an air vacuum pump, there are a few different things you need to know about the different types. Some of the more common types are Plunger vacuum pumps, Rotary vane vacuum pumps, and Rotary lobe blowers. Different types of pumps will have different purposes, and it is important to know which one suits your needs before purchasing. Read on to learn more about these different types of air vacuum pumps:
Rotary Lobe Blowers
Rotary lobe blowers in air vacuum pump systems are the most reliable, energy efficient, and compact air compressors available today. They utilize shock waves and faster-moving waves to compress air. This feature allows for a compact size and a low-maintenance design. Additionally, these air compressors are highly durable and do not require inertial or hardware components, making them a great choice for industrial processes.
A rotary lobe blower uses the Roots wave compression principle to increase pressure. The rotor lobes move from the inlet to the discharge pipe, forcing air in and out of the system. These blowers operate at a specific output level to overcome resistance. But this high-energy flow requires a damper. Fortunately, many industrial vacuum pumps now have rotary lobe blowers.
Plunger Vacuum Pumps
A plunger vacuum pump works in the same way as a reciprocating piston pump, but with a longer solid cylinder. The plunger is made of hard-coated ceramic, and its long profile allows for a stationary high-pressure seal that is attached to the piston. The long profile of the plunger also allows for more complex sealing systems. This makes plunger vacuum pumps ideal for demanding environments. They also offer greater suction power than piston vacuum pumps.
The pump body, or cylinder, includes a driving motor and an oil tank. There is also a circulation system. The oil filter is connected to the oil tank through an oil conduit. The pump body is then connected to the oil cooler and evacuation chamber by an oil conduit.
Rotary-Vane Vacuum Pumps
A rotary-vane vacuum pump is an efficient solution for medium and low vacuum applications. These pumps use positive displacement, wherein a volume of air or gas is mechanically reduced, which creates a vacuum. Single-stage rotary vane pumps are robust, oil sealed, and can operate at a variety of inlet pressures. They are suitable for laboratory use and are often used as backup pumps for turbo pumps. In addition, these pumps are easy to install and provide reliable performance.
Rotary vane vacuum pumps are available in a variety of sizes and designs. They can be lubricated or dry-running. Their operation relies on the principle of reducing the volume to increase pressure. The rotor is eccentrically located within the pump’s housing.
