9. Other excellent property
We provide finished and semi-finished ceramic piston rod.
Ceramic piston rod is made of advanced ceramic materials, zirconia, alumina, silicon nitride, etc., through molding, processing, sintering and other processes.
Ceramic piston rod has excellent ceramic properties.High temperature and pressure resistance, corrosion resistance, acid and alkali resistance, hardness.
Piston rod is a connecting part that supports piston to do work. Most of it is used in the moving parts of oil cylinder and cylinder. It is a moving part with frequent movement and high technical requirements.Taking the cylinder as an example, it is composed of cylinder cylinder, piston rod (cylinder rod), piston and end cover.
High heat and temperature:
The ceramic have a excellent high heat temperature resistant ability. Ceramic can be used under 2200 ℃ high temperature environment.up to 10∧13 Coefficient of thermal expansion ( 10∧6) from 20 - 1000°C. up to 2800°C Melting point.
Wear Hardness abrasion:
The ceramic is better wear and abrasion resistant property than metal. The ceramic hardness (mohs)up to 9, HRA 80-90.
Ceramic hardness is not second only to diamond, but far beyond the wear resistance of steel and stainless steel
The role of the piston rod is to connect the piston and the crosshead, transfer the force acting on the piston and drive the piston movement.
The piston rod assembly includes:
Piston, piston ring, support ring, piston rod, etc.
According to the different structural forms, the piston can be divided into cylindrical piston (length than diameter), disc piston (length than diameter), differential piston, combined piston and plunger piston.
