Vacuum pump: the vacuum level is insufficient. What could be the reason?
Thread Content
I received a vacuum pump today, and the customer reported that the vacuum level is insufficient. I’m not sure what the cause might be; I’d appreciate it if everyone could share their insights. Thank you all: handshake
Generally, it is caused by air leakage. In the case of a water ring vacuum pump, there are two components known as \"hinges\" at the end plates (flange plates) on both sides of the vacuum pump; check to see if there is a problem with the sealing of these hinges； Or the impeller diameter of the vacuum pump is incorrect, resulting in a large gap between the impeller and the casing, which affects the vacuum level.
Please be more detailed. It’s hard to determine the cause when it comes to certain types of pumps
If there is air leakage or an excessive amount of gas release from the medium, it is necessary to analyze the situation based on specific circumstances.
You can consult the manufacturing unit, as you didn’t mention any vacuum pump, so it’s impossible to determine.
New pump, insufficient vacuum level; the system itself may be the cause. The old vacuum pump is responsible for the low vacuum level, and wear of the internal components of the vacuum pump should be considered
OP, is the pump of your client a new one or an old one? Please be more detailed, otherwise everyone will just be making random guesses and analyses. It is recommended to check several aspects: 1. Whether the amount of sealant injected, as well as the pressure of the sealant, are normal, and whether there are any blockages in the relevant pipelines ? 2. Is the sealant temperature too high due to factors such as poor cooling water flow? ? 3. Is the inlet filter clogged, or is there an issue with the opening degree of the inlet valve, resulting in insufficient vacuum level? ? 4. Additionally, if it’s a new pump, is the rotation direction reversed? ? 5. An even more bizarre possibility: could it be that the instrument display is faulty, when in fact there’s no problem? Haha, it’s just random speculation. The poster has provided too little information. . . . . .
Are there any air leaks in the process system? Are the flexible valve plate components on both sides of the pump damaged? Has the gap between the rotor and the distribution plate increased due to wear? Is the shaft seal leaking? Wait
