If the compressor is operating normally, the outlet pressure is 5. 0mpa The inlet valve suddenly closes due to lack of interlocking of the instrument air. What will happen? Will it cause some damage to the compressor? Has anyone experienced this?
In this way, the inlet pressure can form a vacuum, and the pressure difference between the inlet and the first-level outlet becomes larger. What will happen if this happens?
The compressor will create a vacuum and may explode, but it is usually a manual valve and rarely a control valve.
If your inlet valve suddenly closes, if it is a centrifugal compressor, surge will definitely occur, which may cause an unusual sound or cause damage to the compressor and cause an accident.； However, your protection system will definitely start automatically at this time. For example, the anti-surge valve will automatically open to protect the compressor.
The anti-surge valve will automatically open to protect the compressor.
Our entrance this time is a Flowserve remote control ball valve, which costs millions. If the anti-surge valve opens automatically when the inlet is closed, it should be fine!
1. The compressor enters the surge operating zone and the anti-surge circuit opens.； 2. The compressor gas is compressed repeatedly, and the inlet and outlet temperatures rise rapidly. ； 3. Gas systems such as synthesis towers have no flow and abnormal changes in reaction temperature.
2. The compressor gas is compressed repeatedly, and the inlet and outlet temperatures rise rapidly.； With interstage and anti-surge coolers, the temperature can be controlled
