[Q&A No. 216] 2016.11.22 Why does the temperature of the compressor valve increase due to salt formation? Reference will be visible after replying * * , you can score points by answering the key points. According to the principle of a reciprocating machine, the outlet valve of the cylinder should be closed during the suction process, and the inlet valve should be opened. Once salt forms, the exhaust valve will not close tightly, and gas will flow back from the outlet during the suction process. These gases themselves are compressed higher-temperature gases. When these high-temperature gases are compressed and discharged, the temperature of the exhaust valve will increase, and the cycle repeats. 2016 Q&A summary post (updated to November~~~~) http://bbs.hcbbs.com/thread-1597792-1-1.html Recruiting sponsors for the “2016 Haichuan Top Ten Member Selection Event” http://bbs.hcbbs.com/thread-1628108-1-1.html( Source: Haichuan Chemical Forum)
The compressor should refer to a reciprocating compressor. Salt formation in the gas valve should be equivalent to a fault in the gas valve and the backflow of high-temperature compressed gas. But why does salt build up?
Upstream raw gas carrying~~~~~ Some places use reformed hydrogen~~~
According to the principle of a reciprocating machine, the outlet valve of the cylinder should be closed during the suction process, and the inlet valve should be opened. Once salt forms, the exhaust valve will not close tightly, and gas will flow back from the outlet during the suction process. These gases themselves are compressed higher-temperature gases. When these high-temperature gases are compressed and discharged, the temperature of the exhaust valve will increase, and the cycle repeats.
According to the principle of a reciprocating machine, the outlet valve of the cylinder should be closed during the suction process, and the inlet valve should be opened. Once salt forms, the exhaust valve will not close tightly, and the gas will flow back from the outlet during the suction process. These gases themselves are compressed higher-temperature gases. When these high-temperature gases are compressed and discharged, the temperature of the exhaust valve will increase, and so on.
Salt formation will cause the exhaust valve to not close tightly, so gas will flow back from the outlet during the suction process. These gases themselves are compressed higher-temperature gases. When these high-temperature gases are compressed and then discharged, the temperature of the exhaust valve will increase, and the cycle repeats.
The valve plate is not closed tightly, causing the high-temperature gas to flow back after compression, which repeatedly causes the temperature of the valve and exhaust steam to rise.
This will cause the air valve to leak. If the valve plate of the air valve is broken and the valve spring fails, it will cause loose sealing and air leakage in the suction, which will reduce the air intake volume, increase the temperature in the cylinder, and increase the exhaust temperature.； A leaky exhaust valve will reduce the exhaust volume and air intake volume, causing the compressed gas to flow backwards, thus increasing the temperature in the cylinder and the exhaust temperature.
After salt formation, the gas valve will not seal well, and the gas valve will not function as a one-way valve, causing part of the gas to be compressed repeatedly, causing the temperature to rise.
