Silicon Nitride Ceramic Plunger The high wear resistance of high-pressure ceramic plungers is much higher than that of traditional metal plungers. It is an ideal substitute for metal plungers and greatly extends the service life of related components. This is also related to its unique manufacturing process. The high-pressure ceramic plunger working surface adopts a micro-porous structure obtained by a unique processing method. This form has self-lubricating effect, which changes the mechanism of sliding friction and lubrication of the conventional plunger pump.The inner surface of the high-pressure ceramic plunger adopts a fluid structure without dead angles and grooves; and the inner cavity surface is matched with the surface of the plunger, and is also processed to the mirror surface by an advanced high-precision inner and outer cylindrical grinding machine, and the outer surface is vibrated and polished for convenient cleaning. ,disinfection.
