Marelan – Sempat hebohkan masyarakat, Kebakaran besar terjadi di Gg.Rambutan Jalan Ileng, Lingkungan II, Kelurahan Rengas Pulau, Kecamatan Medan Marelan.
Sijago merah melahap satu unit rumah semi permanen milik Lili Herawati (50), Sekitar Pukul 11.00. WIB Jumat (19/07/2024).
Akibat kejadian tersebut, dua orang atas nama Lola Ariska (19) dan Safril Gunawan (25) mengalami luka bakar dan langsung dibawa kerumah sakit terdekat.
Sejumlah mobil Damkar terus berdatangan dengan mengeluarkan suara sirene yang memekakkan anak telinga guna menjinakkan Sijago merah dengan semprotan air.
Penyebab kebakaran belum diketahui pasti dan asal api masih dalam penyelidikan pihak kepolisian dari Polsek Labuhan.
Kepala lingkungan II M Yusuf mengatakan dirinya baru diberi kabar sekitar pukul 11 siang.
Meski sejumlah mobil pemadam tiba di lokasi namun tampak rumah warga tersebut menghitam karena sudah ludes terbakar.(Gs/Mrl).
[b] Dynamic Balancing: An Introduction and Examples
[/b]
[b] What Do You Mean by Dynamic Balancing?
[/b]
Dynamic balancing distributes mass within a rotor to minimize vibration during its rotation. This is essential for high-speed rotating equipment, including fans, pumps, turbines, and other machinery, where uneven mass distribution can cause significant vibrations, impacting the equipment’s lifespan and efficiency.
Dynamic balancing includes measuring and adjusting the mass in two planes perpendicular to the axis of rotation. This technique ensures precise mass distribution, reducing vibration and improving the reliability and durability of the equipment.
[b] What is a Common Example of Dynamic Balancing?
[/b]
One common example of dynamic balancing is the balancing of automobile wheels. During vehicle operation, especially at high speeds, even a slight imbalance in the wheels can cause significant vibrations, negatively impacting driving comfort and safety.
To resolve this issue, each wheel is dynamically balanced. This involves placing balancing weights at specific points on the rim to counteract imbalances and minimize vibrations. This process allows automobile wheels to rotate smoothly and without vibrations at any speed.
[b] What Sets Static and Dynamic Balance Apart?
[/b]
Balancing can be categorized into two main types: static and dynamic.
[b] Static Balancing Method
[/b]
Static balancing involves balancing mass in one plane. This method eliminates imbalance when the rotor is stationary. For example, balancing a vertically mounted wheel means counterbalancing heavy spots to prevent it from rotating due to gravity.
[b] Dynamic Balancing Technique
[/b]
Dynamic balancing, as stated earlier, involves balancing mass in two planes. This method is crucial for high-speed rotating equipment because an imbalance in one plane can be compensated by an imbalance in the other, requiring a comprehensive approach to achieve perfect balance.
Dynamic balancing is a more complex and accurate process than static balancing. It necessitates the use of specialized equipment and software to measure vibrations and determine where mass should be added or removed to achieve the best results.
[b] Conclusion
[/b]
Dynamic balancing is a crucial process for maintaining the high performance and longevity of rotating equipment. Proper balancing reduces vibrations, decreases wear and tear, and prevents breakdowns. Examples such as automobile wheel balancing illustrate the importance of this process in everyday life. Understanding the difference between static and dynamic balancing helps in selecting the right method for specific applications, ensuring reliable and efficient operation of machinery.
