Ceramic plunger is a high-tech new product developed in recent years, the middle part can be bonded with embedded metal mandrel, the outer tube is ceramic material, the ceramic tube and the mandrel are threaded, and the anaerobic adhesive is used to prevent loose. Performance and service life of ceramic plunger? It has to do with these factors!
Compared with the metal plunger, the ceramic plunger has the obvious characteristics of low roughness, low friction resistance, high temperature resistance, corrosion resistance, etc., and its design service life is 3 years.
Series of alumina zirconia ceramic plungers produced by precision processing are widely used in petroleum, chemical, food, textile, medical and other industries. Ceramic plunger has very high wear resistance, corrosion resistance, impact resistance, the precision between the shaft and the jacket of the ceramic plunger can reach 0.001mm, and the finish can achieve the mirror effect, thereby reducing the friction coefficient, greatly improving the service life of the plunger, and improving the boot efficiency.
The ceramic plunger is selected by isostatic pressing to ensure the consistency of density, so that it will not crack due to the doubt of density in the work, the appearance of diamond fine polishing, so that the surface roughness is reduced to a minimum, in order to add lubricity and durability.
According to the current oil, chemical, food machinery and other professional applications of the metal plunger pump selected poor corrosion resistance, short life shortcomings and the existing ceramic plunger combination is not reliable, simple drop status and research and development of another high-tech commodity. Its characteristics are: the contact surface and working surface with the medium are zirconia ceramics, the plunger and the metal handle are mechanically combined, and the adhesive is filled between the ceramic and the metal handle to avoid loosening of the thread. Compared with the existing ceramic plunger, it has the characteristics of anti-falling, strong joint and high strength. The service life of the zirconia ceramic plunger is 10 times higher than that of the metal plunger, and it can also increase the life of the sealing filler, with extremely high wear resistance, corrosion resistance and impact resistance.
