Information On Rotary Oil Vane Vacuum Pump

A pump for positive displacement, which consists of vanes and is mounted to a rotor, rotating in a cavity is the rotary oil vane vacuum pump. At times, the vanes tend to have lengths, which are variable and are tensioned for maintaining the required contact with the walls when the pump rotates. These vane pumps are mostly used as hydraulic pumps of high pressure in automobiles.

In automobiles, these pumps are used for power steering, automatic transmissions, and for supercharging. These pumps can be used for gas applications of low-pressure like the air-injection, which is secondary to the control of emission of auto exhaust. These are further used in systems of chemical vapor deposition of low pressure.

Selecting the Oil for a Rotary Vane Pump:

For the apt performance of rotary vane pumps, it is essential to make the right choice of the oil. Wrong oil is the main reason to cause the damage to the pump. The oil used needs to meet the specific standards. The chosen oil needs to have low vapor pressures, even at a high temperature. This also needs to have a low backflow and extreme qualities for lubricating. You also need to make sure that the oil used is resistant to aging due to the usage, which is demanding. Finally, this needs to be resistant to any chemical breakdown and oxidation.

Types of Rotary Vane Oils:

Some of the oils available for the rotary vane pumps are listed below for your reference.

• Rotary Vane oil K8: This K8 is considered as ‘special’ oil. It is specifically designed for the applications involving the extracting of acid vapors. This oil does not perform well with the water vapors, as it is hygroscopic. The alkaline additive in this K8 protects the pump from the acidic vapors. This is the reason it is not essential to change it often. You need to change this if the pump is shut down for a long period of time or when it is not in use.

• Rotary Vane Oil B: With the low pressure of the vapor in this oil B, you can look forward to a high rating in the viscosity. This is resistant to oxidation and chemical breakdown. This oil works aptly for the pumping of alkaline, strong oxidants and acid vapors. The Pump oil B tends to be more superior as compared to mineral oils, as it is less damaging when it comes in contact with the skin.

• Silicone SI2: When you require a high durability, this silicone SI2 works out to be an apt choice. Due to the chemical components of this oil, it works out to be resistant to gases that can damage the vapors or other oils from solvents.

Maintenance of The Rotary Oil Vane Vacuum Pump:

Most of these rotary vane pumps are used for 24 hours in a day. Preventive maintenance tends to be an essential requirement, as this can increase the lifespan. You need to opt for the following preventive measures:

• A regular change of oil can prevent pump failure. With this oil change, there are fewer chances of the oil getting contaminated. This oil change depends on the environment in which the pump is used.

• Solids or liquids entering the pump can lead to the failure. These need to be replaced as and when required.

• Once the vane of the pump gets one fourth shorter than what it was you need to replace this. At this time of replacement, it is advisable to replace the gaskets and bearings also. Look for reliable manufacturers of rotary oil vane vacuum pump online, as they offer the best replacement kits and accessories.
