Discussion on solutions for the contamination of the lubricating oil in the bearing housing of dry vacuum pumps
Thread Content
This unit uses dry screw vacuum pumps, and the material is an acidic gas. During operation, the gas in the rotor chamber enters the bearing housing, contaminating the oil and preventing the bearings from operating for extended periods, thus requiring routine maintenance. (With a skeleton oil seal) How to prevent gas from entering the bearing housing and contaminating the oil, thereby extending the service life of the bearings. Dear sea friends, please speak up actively
The key question is what the lifespan of this device is when used in its original capacity. If the lifespan is short, it should be a problem with the design of the device itself. If the problem arises the day after, it should be due to quality issues in the maintenance work. For reference.
Just like this after using it? Should I use it for some time? The seal can only be replaced
There is a problem with the design, and the manufacturer is unable to resolve it at the moment
The seal has been replaced, but this issue still occurs. Is there any way to relieve this situation?
Is nitrogen being introduced into the bearing housing? Will it blow the oil into the rotor chamber and thus into the system?
He means to use nitrogen for isolation, right?
The bearing chamber is protected with a slight positive pressure of nitrogen. We improved it many years ago. For more specifics, we can discuss Tenair vacuums in detail
It is recommended to use a five-point mechanical seal or a nitrogen seal to achieve zero leakage
The mechanical seal cannot be lubricated. Because the ingress of gas can contaminate the lubricating oil. Mechanical seals can also get damaged.
