Reciprocating air compressor valve problem
Thread Content
Is it better to use steel or PEEK for the valve material of a reciprocating air compressor? What are the advantages and disadvantages of the two in terms of performance and price? If steel parts are used, what materials are used to make the valve seats and valve discs, and what kind of heat treatment is required?
This choice 1 should be based on your compression medium and choose materials such as Famen valve plates.； 2. If both materials are suitable, select the valve manufacturing material based on manufacturing difficulty, material cost, and service life. ；
Nowadays, PEEK is more common and has better impact resistance, but the material is more expensive. The impact of metal is greater and its service life is shorter. It is better to use 2Cr13 for the valve seat.
When designing an air valve, consider the air exhaust volume, opening stroke, exhaust temperature, rated operating speed, etc. Otherwise, the air valve will have poor reliability and short service life.
Nowadays, it is more common to use 1cr13, 2cr13 and PEEK. PEEK has better impact resistance, the material price is more expensive, but the service life is long. The impact of metal is greater and its life is shorter. It is better to use 1cr13 or 2Cr13 for the valve seat.
