How to Use Ceramic Plunger and Ceramic Cylinder for Petroleum Machinery?

A ceramic plunger is commonly used in petroleum machinery. It consists of a plunger body with a connecting end, a metal core body on the inside, and a ceramic material shell on the outside. A sealing layer is present at the contact surface between the core and shell, and a plugging head is attached to the end of the plunger body.

This technical scheme provides superior wear resistance to the plunger due to the ceramic coating on the metal core body. In fact, the wear resistance of a ceramic plunger can exceed that of a metal plunger by 5-10 times. Furthermore, the ceramic material's corrosion resistance addresses the corrosion problem of the plunger, thereby significantly prolonging its service life. As a result, a plunger pump equipped with a ceramic plunger can operate normally in harsh working environments.

The plunger body also features a plugging head, which enhances its strength and creates a more compact combination between the two.

It is the main consumption of cylinder parts, its service life directly affects the use efficiency, frequent replacement not only consumes a lot of manpower and financial resources, reduce drilling efficiency, but also indirectly increase the cost of transportation and storage pump accessories. At present, many metal cylinder liners (including single metal and double metal cylinder liners) have some problems, such as unsatisfactory service life and frequent replacement.

Master the introduction of advanced technology, research and development of the engineering ceramic material instead of metal materials, manufacture of metal ceramic composite cylinder products. Zirconia / alumina ceramic material has excellent properties such as high hardness, high strength, wear resistance and corrosion resistance. It has solved a series of problems of metal cylinder liner. The ceramic cylinder has the following advantages:

1, long service life. Under the same conditions, the service life of the cylinder is more than 8 times.

2, the machining accuracy is high, the piston service life to a certain extent.

3, the worse drilling conditions are, the more obvious advantages are.

4, greatly reduce the cost of transportation and storage crew in the production process, reduce the labor intensity of workers.

5, ceramic materials are not rust, corrosion resistance effect is obvious.

Advanced Ceramic Materials (ACM) has strong technical force, can produce a variety of pump type and size of ceramic cylinder liner, a variety of geophysical industry, small ceramic cylinder has also been widely used. We can also design and produce special size ceramic cylinder sleeve according to customer drawings or requirements.
