you know how rotary vane vacuum pumps are used to suck up dry gases from containers? Well, they’re not really meant for sucking up gases that have water or corrosive stuff in them.
And if there’s too much oxygen or other gases that can react with the oil in the pump, it can cause problems. That’s where BTLAS comes in.
They make intake filters that can get rid of impurities and water from the air before it gets into the pump.
This way, the pump can work better in different conditions and with different types of gases.
Now, these pumps use oil for lubrication, which means they might not be as versatile as some other pumps. But they’re still pretty popular because they’re easy to operate and maintain.
And if you want to keep your pump running smoothly for longer, you gotta do regular maintenance and cleaning.
This includes taking apart the pump and replacing the intake filter and vacuum pump oil. You also need to use special metal cleaning agents and check for any worn or damaged parts.
If you find anything, replace it right away. Here’s how you take apart and put back together a rotary vane vacuum pump:
First, remove the pump from the equipment and drain the cooling water.
Then, open the oil drain plug and rotate the drive pulley to release the oil.
Next, remove the vacuum pump filter, including the intake filter, exhaust filter, and oil filter. Take off the belt, pulley, and key, and then remove the low-vacuum end cover.
Take out the sealing ring and pull out the positioning pin.
Carefully remove the low-vacuum rotor and vanes, making sure to hold onto the vanes so the spring doesn’t pop out and damage them.
Use the same method to remove the high-vacuum end cover and extract the high-vacuum rotor and vanes.
To make sure there’s enough space between the rotor and the pump chamber, position the exhaust port downward when reinstalling the rotor.
This will let the weight of the rotor seat it properly against the pump chamber, ensuring correct clearance at the cutting point.
Once you’ve cleaned everything, put the pump back together following the right steps. Before you turn it on again, do a test evacuation to check for leaks or other issues. Most people can do this process themselves.
The intake filter is super important for the vacuum pump, so companies should set a reasonable replacement schedule based on their specific needs.
