The air cannon piston is a core component of the air cannon, with its characteristics and application advantages mainly reflected in the following aspects:

Material and Abrasion Resistance

Air cannon pistons are typically made from high-performance, wear-resistant, and corrosion-resistant materials such as polyamide fiber, high molecular weight polyethylene, and sulfur-activated polyurethane. These materials offer excellent wear resistance, impact resistance, and corrosion resistance, ensuring the pistons operate stably for extended periods under harsh working conditions. Some pistons are also externally fitted with steel sleeves to enhance their overall strength and wear resistance, thereby further extending their service life.

Sealing properties

Air cannon pistons are typically equipped with piston rings and rubber seats for sealing, which effectively prevent gas leakage and ensure the air cannon achieves the expected pressure increase upon release. The sealing rings and rubber seats are usually made of special materials that are heat-resistant, oil-resistant, and water-resistant, such as butyl rubber, maintaining excellent sealing performance under high pressure and long stroke conditions.

Structural Features

Some air cannon pistons are equipped with wear-resistant devices at both ends. This design not only enhances the overall sealing of the piston and sleeve but also reduces air leakage when the air cannon is not in use. The rear of the piston usually features a spring or shock absorber to prevent material from entering the piston and cannon body, while also aiding in the reset and shock absorption of the piston during movement. 1

Work Performance

The air cannon piston can withstand the impact of high-pressure gases and effectively compress and release them, achieving a high-speed, efficient explosion effect. Thanks to the use of high-performance wear-resistant materials and optimized structural design, the air cannon piston generates relatively low noise during operation, contributing to an improved working environment.

Applicability

Air炮pistons are suitable for various air炮units, such as the KQP series and KL series, and can meet the usage requirements of different industries and working conditions. Some manufacturers also offer customized services, which can be designed and manufactured according to the actual needs of the customer to satisfy specific working conditions.‌1

In summary, the air cannon piston ensures stable operation and high efficiency under various working conditions, thanks to its high-performance wear-resistant material, excellent sealing, and optimized structural design.
