Product Parameters
1. Product Overview
This is a description of HNA's advanced high - pressure ceramic plunger, highlighting its superior features, performance, and wide - ranging applications.
2. Key Features
Manufacturing and Material
- Forged Plunger Core: The plunger core is crafted through high - pressure forging. It uses materials like AISI 4135 (35CrMo) or AISI 5140 (40Cr), with the option of customized materials. High - pressure forging enhances the core's density and strength.
- Advanced Ceramic Sleeve: An advanced zirconia - based ceramic sleeve is used. Zirconia ceramics are known for their high strength, hardness, and excellent chemical stability.
Heat Treatment
- World - class heat treatment is applied to the plunger core. This process optimizes mechanical properties such as tensile strength, yield strength, Charpy impact resistance, and elongation. It also significantly improves abrasion, temperature, and corrosion resistance, exceeding API standards. As a result, the service life of the plunger is extended.
Precision Machining
- The use of world - class precise machining crafts ensures high - precision dimensions. This close - tolerance fit allows for the best possible matching with the cylinder, reducing wear and tear during operation and improving overall efficiency.
Ceramic Sleeve Characteristics
- High Hardness: The ceramic sleeve has a hardness greater than 92 HRC. This extreme hardness makes it highly resistant to abrasion, ensuring a long - lasting performance even under high - pressure and high - friction conditions.
- Temperature Resistance: It can operate within a temperature range of 20 - 350°F. This wide temperature tolerance enables the plunger to be used in various environments without significant degradation of performance.
- Corrosion and Abrasion Resistance: The ceramic sleeve offers extremely perfect performance in terms of corrosion and abrasion resistance. This is crucial in applications where the plunger is exposed to harsh chemicals or abrasive substances.
- Self - Lubricating Effect: The unique machining of the ceramic plunger's working face creates a microstructure with a self - lubricating effect. This changes the traditional sliding friction and lubrication mechanism of metal plungers, reducing friction and wear, and potentially eliminating the need for additional lubricants in some cases.
Design Features
- Fluid - Friendly Inner Cavity: The inner cavity surface has a fluid structure, free of dead angles and grooves. This design allows for smooth fluid flow, reducing the risk of clogging and improving the efficiency of the system.
- Mirror - Finish Surfaces: Both the inner cavity surface and the plunger surface are machined to a mirror finish using advanced high - precision internal and external grinders. The outer surface is vibration - polished. These smooth surfaces are not only easy to clean and disinfect but also reduce friction and wear.
- Sealing and Disassembly: The product has a fine - sealed structure, preventing fluid leakage. At the same time, it is easy to disassemble, which simplifies maintenance and replacement processes.
Performance Ratings
- High - Pressure Resistance: The plunger is rated for a maximum pressure of up to 20,000 PSI. This high - pressure rating makes it suitable for demanding applications in high - pressure systems.
- Long Service Life: Due to its excellent material properties, advanced manufacturing processes, and superior design, the plunger has an extremely long service life, reducing replacement costs and downtime.
Interchangeability and Sizes
- It is fully interchangeable with major plunger types, providing flexibility for users to replace existing plungers in their systems. Available sizes range from 2.5 inches (63.5 mm) to 6.5 inches (165.1 mm), catering to different application requirements.
Applications
- HNA's advanced high - pressure ceramic plungers can be widely used in various heavy - machinery applications, including mining machinery, cross - tunnel machinery, civil construction machinery, heavy - duty trucks, and special trucks. Their high performance and durability make them ideal for these demanding environments.
3. Product Series and Customization
- Product Series: The HNA - PF - PZ series offers HNA Advanced High - Pressure Ceramic Plungers in sizes from 2.5 inches (63.5 mm) to 6.5 inches (165.1 mm).
- Customization: Customized specific designs and series of HNA Advanced High - Pressure Ceramic Plungers are available, meeting both API and non - API standards. This allows customers to get products tailored to their specific needs.
