A rotary dry vane vacuum pump is a rotary displacement pump. The pumping system comprises a housing and an electrically installed rotor. The system also consists of vanes that would be moving radically under spring force and an inlet and an outlet where the outlet valve would generally be sealed, and the inlet valve is designed as a vacuum safety valve that would always remain open during operation. The working chamber of the pump would be in the housing of the pump. The entire working chamber is divided into two separate parts that have two volumes. The gas would start flowing into the enlarging section as the rotor turns until it is sealed off by the second vane. The enclosed gas would be compressed until the outlet valve would open against the atmospheric pressure. When a gas ballast operation is being used, a hole to the outside is opened, which would flow the sealed suction chamber on the front side.

What Are Some of The Features That Would Characterize a Dry Vane Vacuum Pump?

A rotary dry vane vacuum pump has a few characteristics that would distinguish it from some other types of pumps in terms of looks. The pumps generally have a compact design and a light weight feature. These pumps do not make a lot of noise while operating. Also, these pumps do not require a lot of maintenance, though it is advisable to keep them under proper care for sustained use. Some of the pumps would even have particulate filters and silencers built into the pump to protect the pump and for other specialized purposes. These pumps are good at handling vacuum and pressure applications. With these characteristics, they sometimes act as the ideal alternative to the standard oil-sealed rotary vane pumps.

 

What Is the Internal Design of The Pump?

Most of the rotary vane pumps are oil-sealed but the dry vane vacuum pumps are cheaper to use for wide range of various applications due to their robust design and sound performance. The general design of a rotary vane system would consist of the pump housing, along with the vanes that would converge to a common centre. There are also the two openings of the pump and these parts together form the housing. Some of these types of rotary vane pumps are also equipped with a vacuum safety valve. The safety valve would disconnect the pump from the vacuum recipient in the case where there is an intentional or unintentional stoppage. It will use the displaced gas to vent the pumping system, preventing oil from rising in the recipient. The pump starts again after the stoppage, once the pressure in the pump is equal to the pressure in the recipient.

What Are the Functions of The Dry Vane Vacuum Pumps?

The dry vane vacuum pumps find a lot of uses in various industries and fields. The machine can be used to transfuse blood in the field of medicine. Municipal bodies would often deploy such pumps to aerate sewage, dry food products and to remove air from a package. These pumps also find usage in the farming industry. Farmers can use these pumps to pump waters to long distances; hence these pumps provide them an edge where the water source is far away from the fields. These vacuum pumps are also used to provide the braking boosters in the braking system of large trucks. They are considered best when the pump’s exposure to contaminants like water, vapor, and dust is almost inevitable. It finds various applications in the electronics industry, pharmaceutical industry, aerospace and nuclear industry, petrochemicals and oil and gas recovery systems.
