Colper entrega regalos
| Jueves 22 de Diciembre, 2022
Este año se realizó la campaña de donación de juguetes organizada por el Colegio de Periodistas y Profesionales en Ciencias de la Comunicación Colectiva de Costa Rica bajo el lema “Se el héroe que salva sonrisas”, los beneficiados fueron los pequeños de la Fundación Génesis, una organización no gubernamental que atiende población de menores en riesgo social.
La campaña se realizó en alianza con los colegios de Veterinarios, Informática y Computación, Abogadas y Abogados e Ingenieros y Arquitectos de Costa Rica.
Se entregaron poco más de cien juguetes no bélicos para que sean distribuidos entre los niños de la fundación.

Dynamic Balancing: A Comprehensive Guide
Understanding Dynamic Balancing
Dynamic balancing is a critical process in many industrial applications. It refers to the method of balancing rotating machinery, specifically addressing issues that arise when the mass of a rotating object is unevenly distributed. Uneven weight distribution can lead to vibrations and operational inefficiencies, which can cause mechanical failure and increased wear on components. Therefore, achieving dynamic balance is essential to maintain the integrity and increase the lifespan of machinery.
The Difference Between Static and Dynamic Balance
Firstly, it is important to distinguish between static and dynamic balance. Static balance occurs when a rotor is stationary, where the center of gravity is off the axis of rotation due to uneven mass distribution. When the rotor is turned, the heavy side always rotates downward, resulting in a static imbalance. Static balancing primarily focuses on equalizing mass in one plane. However, dynamic balance refers to a scenario where the rotor is in motion, and discrepancies in mass exist in different planes. This type of imbalance not only leads to vibrations but also introduces moments that can further exacerbate wear and tear on the machinery.
The Dynamic Balancing Process
To effectively perform dynamic balancing, a specialized device called a portable balancer or vibration analyzer is used, such as the Balanset-1A. This device is essential for machinery like crushers, fans, turbines, and various types of rotors. The dynamic balancing process generally follows several key steps:
Finalizing the Balancing Process
After corrective weights are installed, the rotor is tested one more time to ensure that vibration levels are within acceptable limits. This confirmation means that the rotor achieves dynamic balance and operates more smoothly, reducing wear and preventing mechanical failure.
Importance of Angle Measurement
Angle measurement plays a crucial role in dynamic balancing. Correctly identifying the angles for weight installation ensures optimal balance. The angle for corrective weights is determined by measuring the position of trial weights and adjusting accordingly. This precise placement is vital for creating an equal and opposite torque, effectively neutralizing the unbalanced forces.
Applications and Benefits of Dynamic Balancing
Dynamic balancing is indispensable across various industries. It is particularly beneficial for equipment operating at high speeds, such as turbines and crushers, where even minor imbalances can have severe consequences. Proper dynamic balancing leads to:
Portable Balancer and Vibration Analyzers
The Balanset-1A is specifically designed for these balancing tasks. With its two-channel capabilities, it allows for dynamic balancing in two planes, making it highly versatile for various rotors including fans, augers, and centrifuges. This device simplifies the dynamic balancing process, enabling rapid analysis and adjustments during maintenance procedures.
Conclusion
Dynamic balancing is a vital practice in industries that rely on rotating machinery. Understanding the intricate processes involved, from the distinctions between static and dynamic balance to the step-by-step procedures for achieving balance, can significantly impact operational efficiency and equipment longevity. Through the use of advanced devices such as the Balanset-1A, achieving dynamic balance becomes a streamlined process, ultimately leading to improved performance and reduced maintenance costs.
