On October 31st and November 1st, 2023, our team was in New Orleans, United States, to participate in the WJTA Conference , the annual conference of the Water Jet Technology Association of the United States.

We had the honor of participating in a special and significant moment. Our engineering supervisor, Fabricio Leinat , addressed a topic of great relevance: Choosing brakes for high-pressure rotary tools .

Check out some of what our expert said:

In the world of high-pressure water jetting, where efficiency , cost and adaptability are crucial, choosing rotary tools equipped with the most suitable braking mechanism becomes a fundamental decision to remain competitive.

Two dominant solutions emerge, each with its own advantages and limitations. One approach uses a centrifugal brake , driven by centrifugal forces and the viscosity of the lubricating fluid. The other relies on the power of magnets , through a magnetic braking system . The choice between these systems directly impacts the efficiency , durability and versatility of rotary tools in various applications in different industries.

By exploring the advantages and limitations of each braking system, we aim to empower industry professionals to make informed decisions aligned with their specific needs. In the competitive environment of industries, a comprehensive understanding of the attributes of centrifugal and magnetic brakes is essential. In this context, Lemasa stands out as the only company to offer both braking solutions, making the choice even simpler and more cost-effective for users.

Advantages and Limitations of Brake Systems

Centrifugal Brakes

Centrifugal brakes demonstrate remarkable effectiveness in challenging environments such as shipyards, refineries or high-temperature locations where tool operation is affected by the environment. Their rotational stability and reliability make them ideal for consistent operation, even in adverse conditions.

• Application in coating removal : Like epoxy paint, these brakes ensure efficient operation, especially at higher speeds . Although they require a significant amount of oil and periodic replacement, their resistance to different temperatures makes them effective against heat. They are ideal for environments with loose or airborne metal particles .

Magnetic Brakes

Magnetic brakes provide precise rotation control , essential for operations such as hydrodemolition or treatments requiring fine surface finishes . Their ability to change rotation by varying the proximity of the copper ring to the magnets is essential to ensure uniform surface treatments .

• Limitation : It is important to note that magnetic brakes can lose efficiency in high temperature environments or when they reach excessive rotations, which can cause overheating and reduce the rotation control power.
