Product Introduction
Marine Air Compressor Piston is a key moving part in marine air compressors. It is installed in the cylinder and works with the piston ring. Its main function is to compress the gas through reciprocating motion and complete the gas intake and discharge process.

Advantages
Sealing
The piston size tolerance is strictly controlled within ±0.02mm, and the surface roughness Ra is controlled below 0.4μm, ensuring the close fit between the piston and the inner wall of the cylinder and the piston ring, reducing gas leakage and friction loss.
Thermal stability
Marine Air Compressor Piston uses high-temperature alloy steel and heat treatment process to ensure that the material maintains dimensional stability under continuous high temperature (up to 300℃) environment, and the thermal expansion coefficient is controlled at about 12×10⁻⁶/K to avoid abnormal fitting clearance or jamming due to thermal expansion and contraction of the piston.
Surface strengthening process
The piston surface can be treated with nitriding or PVD coating technology, which can increase the hardness to above HV900, improve the surface corrosion resistance, and effectively resist salt spray corrosion in the marine environment and chemical erosion in the lubricating oil.

FAQ
Q: What is Marine Air Compressor Piston?
A: The piston is a reciprocating component in the compressor that realizes gas compression. It directly bears the pressure in the cylinder and affects the compression efficiency and equipment life.
Q: What materials are commonly used for pistons?
A: Aluminum alloy, high-strength steel or alloy cast iron are mostly used, taking into account strength, wear resistance and lightweight requirements.
Q: What are the key parameters of piston size and specifications?
A: Mainly including piston diameter, piston ring groove size, piston pin bore diameter, total length and matching tolerance, which must be accurately matched with the cylinder and connecting rod.
Q: How to ensure the sealing performance of the piston?
A: By reasonably designing the piston ring groove and piston ring, ensure that gas does not leak and reduce compression loss.
Q: Is there any special treatment on the piston surface?
A: Common nitriding, carburizing, and spraying hard coatings improve wear resistance and corrosion resistance and extend service life.
Q: Is the piston suitable for high temperature and high pressure environments?
A: High-quality pistons are heat treated and surface strengthened to withstand the high temperature and high pressure working environment of marine compressors.
Q: What are the piston maintenance recommendations?
A: Check the piston ring clearance and wear regularly to keep the lubrication system normal and avoid piston sticking due to lack of oil.
