High packing temperature in reciprocating compressors
Thread Content
What are the main reasons for high packing temperature in reciprocating compressors? What are the treatment methods when the temperature is high, and what cooling methods are used for the fillers?
First, consider adding filler cooling water and ensuring its unobstructed flow； The compressor oil injector must have a supply of lubricating oil to the packing area ； There should be a vent pipe between the filler chamber and the support position ； What remains is to check for damage to the stuffing box, such as damage to the packing rings or the copper rings, and so on
The reasons for high filler temperature are as follows: 1. High frictional force between the filler and the piston rod. This requires technical skills. 2. The packing and piston rod are not sealed properly. 3. The clearance between the packing and the stuffing box is small. 4. The oil injector does not supply oil. 5. Check the cooling water issue. Take measures: 1. Install strictly in accordance with the technical requirements for filler assembly. 2. External cooling water can be used to spray on the outer cover of the stuffing box. 3. Lubricate and cool the piston rod with engine oil.
Compressor valve leakage; carbon deposition can also cause it
