What are the reasons for a sudden drop in vacuum level when a vacuum system is in operation?
Thread Content
Dear Haihao friends, let’s discuss what the possible reasons are for a sudden drop in vacuum level during the operation of a vacuum unit Thank you to all the experts for participating and learning from each other while discussing:handshake:handshake
There are numerous reasons for a decrease in vacuum level; depending on the manufacturing process, the operating conditions, or issues with the system equipment, etc., there are various factors that can lead to such a decrease... Let’s learn and share together~~~~~~
Yes, there are many aspects to the decline in the performance of vacuum units. Problems with the equipment, problems with the process. The cumulative air volume in front of the machine exceeds the load capacity of the vacuum pump
There are really many reasons; when it happens, one has to check them one by one.
Our factory has many vacuum units; I’m here to learn from everyone’s experience
With vacuum units of the same configuration, under the same operating conditions and in the same region of use, the only difference being the manufacturer... why do different results still occur? Let’s discuss this together and analyze why the performance of the vacuum units declines.
From a process perspective, it is closely related to back pressure; whether the inlet filter is clogged also plays a significant role

This topic is too broad; let’s take an example, such as steam turbine units: 1. Failures in the vacuum extraction system, such as damaged exhaust nozzles or scaling； 2. The quality of the steam is poor, and there are leaks in the steam heat exchanger, resulting in an excessive amount of non-condensable gas entering ； 3. An increase in the unit load, such as a higher steam flow compared to before, can also lead to a drop in vacuum ； 4. The condenser does not perform well in terms of condensation; it may be fouled or the temperature of the circulating water may be too high ； 5. The system has leakage points, with air leaking in at locations such as flanges and shaft seals.
The temperature inside is high, and the condensation effect in the pipelines is poor； Blockage in the inlet pipeline ； High volatile content in the low-main component ； Leakages within the vacuum unit itself, etc
