What are the advantages and applications of zirconia ceramic plungers

The advantages of zirconia ceramic plungers
(1) Excellent wear resistance
The zirconia ceramic plunger is made of modern engineering ceramic materials and has been processed by high-precision turning and milling, which has super hard wear resistance. Its Mohs hardness can reach 8-9 grades, and in practical applications, the service life is 10-20 times higher than that of metal plungers. For example, in the application of oilfield water injection pump, the zirconia ceramic plunger can operate for 400 days without wear, while the ordinary steel plunger can only last for 80 days.
(2) Strong corrosion resistance
Ceramic materials have excellent chemical stability and can resist most acids, alkalis, salts and other chemical corrosion. Zirconia ceramic plungers have natural resistance to acid, alkali, salt and other chemical media, and perform well in the transmission of corrosive liquids such as nitric acid, acetic acid, sodium chloride, etc. In medical equipment, environmental engineering, petroleum, chemical and other industries, zirconia ceramic plungers can operate stably for a long time, greatly reducing the maintenance cost and replacement frequency of equipment.
(3) Good high temperature resistance
The zirconia ceramic plunger has excellent high temperature stability, with a melting point above 1500 ° C, which can maintain stable physical and chemical properties at high temperatures. This makes it suitable for high temperature environments, such as aerospace, energy and other fields. Under high temperature conditions, the zirconia ceramic plunger can still maintain good working condition and ensure the normal operation of the equipment.
(4) Excellent sealing performance
The high hardness and low coefficient of friction of the ceramic material make the zirconia ceramic plunger have excellent sealing performance. The microporous structure obtained by the unique processing method on its working surface has a self-lubricating effect, which further improves the sealing performance. In addition, the inner cavity surface of the zirconia ceramic plunger adopts a fluid structure, without dead ends and grooves. It is processed to the mirror surface by an advanced high-precision internal and external grinding machine in conjunction with the plunger surface. The outer surface is vibrated and polished, which is convenient for cleaning and disinfection, and also helps to improve the sealing performance.
(5) Unique lubrication properties
The traditional metal plunger pump needs to add lubricant to reduce the friction between the plunger and the pump cavity during use. The zirconia ceramic plunger adopts a unique processing method, and the microporous structure on the surface has better smoothness and self-lubrication, which changes the mechanism of sliding friction and lubrication of the traditional plunger pump and can greatly reduce the adverse effects caused by the use of lubricants.
(6) Good cleaning performance
The plunger needs to be cleaned and cleaned after a period of normal use to ensure that the plunger will not cause other adverse effects on the pump body. The traditional plunger design has dead ends, grooves or unsmoothness, which causes great difficulties to the cleaning of the plunger pump. The inner cavity surface of the zirconia ceramic plunger is a fluid structure without dead ends and grooves. The inner cavity surface and the plunger surface are processed to the mirror surface by an advanced high-precision inner and outer circular grinding machine, and the outer surface is vibrated and polished, which enhances the smoothness of the plunger surface and facilitates the cleaning and cleaning of the plunger.
(7) Good biocompatibility and environmental friendliness
Zirconia ceramic plunger is non-toxic and harmless, meets food grade standards, and can avoid metal ion precipitation and pollution in the pharmaceutical and chemical industry. At the same time, the production process is environmentally friendly, and there is no harmful decomposition in the natural environment.

Application of zirconia ceramic plunger

Zirconia ceramic plungers are widely used in chemical pipelines, valves, pumps and other equipment. Its chemical resistance can improve the durability and reliability of the equipment, thereby ensuring the continuity and stability of the chemical production process. In the transmission of corrosive liquids, such as the pumping of strong corrosive media such as nitric acid, acetic acid, sodium chloride, etc., zirconia ceramic plungers can withstand extreme working conditions and avoid leakage and equipment damage. In high temperature and high pressure reaction equipment, such as high temperature distillation tower, reactor kettle and other equipment, the thermal insulation performance of ceramic plungers can reduce heat loss and improve energy utilization efficiency.
In fine chemical production, the treatment of high-purity chemicals requires strict pollution prevention. The chemical inertness of ceramic plungers ensures product purity and is suitable for electronic slurry, semiconductor manufacturing and other scenarios. In environmental protection projects, such as sewage treatment, exhaust gas purification and other systems, the corrosion resistance of ceramic plungers can prolong equipment life and reduce maintenance costs.

In the future, zirconia ceramic plungers are expected to make greater breakthroughs and development in the following aspects:
(I) Research and development of high-performance composites
By compounding zirconia ceramics with other high-performance materials, the overall performance of the plunger can be further improved. For example, by compounding zirconia ceramics with carbon fiber, ceramic fiber and other materials, a composite plunger with higher strength, toughness and wear resistance can be prepared. This composite plunger will be able to maintain stable performance under harsher working conditions and meet the special needs of high-end fields such as aerospace and national defense.
(2) Intelligent and automated applications
With the development of industrial automation and intelligent manufacturing, zirconia ceramic plungers will gradually develop towards intelligence. By embedding sensors and smart chips in the plunger, real-time monitoring and remote control of the working status of the plunger can be realized. For example, parameters such as the degree of wear and temperature change of the plunger are monitored through sensors, and data is transmitted to the control center to realize predictive maintenance and fault warning of the equipment. This will greatly improve the operating efficiency and reliability of the equipment and reduce maintenance costs.
(3) Application and expansion in the field of new energy
In the field of new energy, such as electric vehicles, fuel cells, etc., the application of zirconia ceramic plungers will continue to expand. For example, in the electric hydraulic braking system of electric vehicles, zirconia ceramic plungers can be used to make high-performance brake pumps to improve the response speed and reliability of the braking system. In fuel cells, zirconia ceramic plungers can be used to make key components such as gas distributors and cooling systems to improve the performance and life of fuel cells.
