Damn vacuum pump
Thread Content
I was about to fill the catalyst tank with a balancing agent, but the vacuum created by the pump was too poor! Only three tons of agent can be loaded per hour, and the vacuum level can reach up to 0.03 MPa. Let’s discuss what the factors are that affect vacuum level
First, the steam extractor is too small... A vacuum of 500-600 mmHG is needed to effectively extract the catalyst... Use a larger one; with a higher steam flow and greater pressure, it will work better. Second, it might be a problem with your steam... Is the pressure insufficient? Or are the pipes too thin? Check it out, do some calculations, and take a look... :lol
If it was working fine before, two things should be checked: 1. Whether there are any leaks in the system, by carefully examining the flow process. 2. The jet pump is faulty itself; clearing the small orifice inside will resolve the issue.
We plan to switch to mechanical vacuuming to reduce steam consumption.
If it’s a device that has been in use for a long time, it’s probably not because the air pump is too small. The main things to consider are leakage, steam quality, and whether the operation is normal. Sometimes, if the steam valve is opened too wide, it can easily cause a break in the connection; in other words, what I refer to as \"air leakage,\" which prevents proper evacuation
If it was working fine before, there might be catalyst powder and mud blocking it inside.
It’s very likely that the catalyst at the inlet of the steam extractor has become clogged; this can happen if the steam supply wasn’t turned off completely after its last use, or if there was a slight leak.
Check the steam pressure. Also, check whether there are any leaks or openings to the atmosphere in the catalyst tank, and ensure that both the pressurization air and the release air valves are properly closed. When our unit was first turned on, the steam extractor didn’t work very well; after replacing it with a pressure-feeding air manual valve, it worked properly – the original one had some leaks.

The air pump doesn’t work well; air leakage is the first thing to check. There are also aspects such as the steam supply volume and the air pressure for transportation, which the person in charge of the project should take into consideration. According to the original poster, it’s either that maintenance work has started or a new installation is underway; it is recommended to consult with the manufacturer of the gas pump to check whether there is a mismatch or quality issues with the pump.
If there is a filter at the steam inlet of the air extractor, it may also get clogged
The catalyst is being added slowly: 1. The system is leaking. 2. Steam extractor failure. 3. Pipeline blockage. 4. Adjustment issues.
