The materials of piston air compressors mainly include the following:
Cylinder block and cylinder head: Usually made of aluminum alloy, ductile iron or steel. Aluminum alloy is light and has good thermal conductivity, suitable for small air compressors; ductile iron can improve vibration resistance and wear resistance, suitable for large air compressors; steel has better strength and high temperature resistance, suitable for high-pressure air compressors.
Piston and piston ring: Pistons are usually made of cast iron or aluminum alloy, and piston rings are usually made of high-temperature alloy or stainless steel. Choosing the right material can effectively improve the performance and life of the air compressor.
Valve and valve seat: Valves are usually made of stainless steel, cast iron or aluminum alloy, and valve seats are generally made of wear-resistant alloy materials. The choice of these materials directly affects the sealing and durability of the air compressor.
Gears and bearings: Gears are usually made of alloy steel or hard alloy, and bearings are generally made of high-strength alloy steel or special wear-resistant materials. High-quality materials can reduce noise, improve transmission efficiency and extend service life.
Cooler and filter: Coolers are generally made of copper-aluminum composite materials or stainless steel, and filters are usually made of graphite, cellulose or special alloys. The choice of these materials affects the heat dissipation and gas filtration effect of the air compressor.
Other key components: For example, the piston ring is made of high-quality steel with high-quality rubber gaskets, which is not only wear-resistant but also more durable, which can effectively reduce the noise during machine operation and make the machine run more smoothly.
