Ceramic plunger is a common industrial part, widely used in various mechanical equipment. It has the characteristics of high strength, wear resistance, corrosion resistance, etc., so it performs well in some special working environments. This paper will discuss the technical parameters of ceramic plunger in detail, including material, size, surface treatment and so on.

Ceramic plunger material

Ceramic plungers are usually made of high purity alumina ceramic materials. This material has excellent mechanical properties and chemical stability, and can maintain stable performance under high temperature, high pressure and corrosive environments. At the same time, high purity alumina ceramic materials also have excellent insulation properties and heat conduction properties, suitable for various industrial applications.

Size of Ceramic plunger

The size of the ceramic plunger can be customized according to the specific application requirements. Generally speaking, its diameter ranges from 1mm to 50mm, and its length ranges from 5mm to 500mm. Through reasonable size design, it can meet the requirements of different mechanical equipment and ensure its normal operation.

Surface treatment of Ceramic plunger

In order to improve the performance and service life of ceramic plunger, surface treatment is often required. The main surface treatment methods include grinding, polishing and coating. Grinding can improve the surface finish and precision of the ceramic plunger, and polishing can further improve its surface quality. The coating can increase the wear resistance and corrosion resistance of the Ceramic plunger and extend its service life.

Technical parameters of Ceramic plunger

Intensity

The strength of Ceramic plunger is one of the important indexes to evaluate its performance. Generally speaking, the strength of the Ceramic plunger is between 200MPa and 500MPa. The high-strength ceramic plunger can withstand greater loads and improve the efficiency and reliability of mechanical equipment.

Density

The density of the ceramic plunger is also a key parameter. In general, the density of the Ceramic plunger is between 3.5g/cm and 6g/cm. Higher density can increase the hardness and strength of the Ceramic plunger, thereby increasing its service life.

Coefficient of thermal expansion

The coefficient of thermal expansion of the ceramic plunger is the proportion of its length change when the temperature changes. The coefficient of thermal expansion of the ceramic plunger is usually between 5×10-/°C and 10×10-/°C. The lower coefficient of thermal expansion can reduce the size change when the temperature changes and improve the stability of the Ceramic plunger.

Thermal conductivity

The thermal conductivity of Ceramic plunger is also an important technical parameter. In general, the thermal conductivity of the ceramic plunger is between 10W/ (m·K) and 30W/ (m·K). The higher thermal conductivity can improve the heat dissipation capacity of the ceramic plunger and avoid the performance loss caused by overheating.

Applications

Ceramic plunger is widely used in various industrial fields because of its excellent performance. It is often used for sealing devices in high temperature, high pressure and corrosive environments, such as pumps, valves and pressure vessels. At the same time, ceramic plungers are often used in precision instruments and medical devices, such as optical instruments and orthopedic implants.

Ceramic plunger is a kind of industrial part with excellent performance, which has the characteristics of high strength, abrasion resistance and corrosion resistance. Through reasonable material selection, size design and surface treatment, its performance and service life can be further improved. The technical parameters of ceramic plungers include strength, density, coefficient of thermal expansion and thermal conductivity, which are essential to meet the needs of different applications. In various industrial fields, ceramic plungers have a wide range of application prospects.
