Working Conditions Background and Requirement Analysis
· Equipment: Household booster pump, weight approximately 20-30kg, dimensions 212mm × 268mm.
· Core Issue: The installation location is close to residential spaces, with high requirements for vibration transmission and structural noise control.
· Challenge: The homemade steel plate base is prone to resonance with the pump body, causing low-frequency humming noises to penetrate the walls, severely impacting rest.
Recommended Solution
· Customized reinforced concrete vibration isolation base, paired with ALJ-170150.
· Based on the "Law of Mass," the recommended base mass is 3 times the equipment weight (approximately 60-90kg).
Technical Principles and Core Advantages
1. Lowering the Natural Frequency and Improving Vibration Isolation Efficiency:
The steel plate base is lightweight, with high stiffness and natural frequency, making it prone to resonance with the low-frequency vibrations of the pump. In contrast, the concrete vibration isolation base uses its large mass to significantly reduce the system's natural frequency, effectively avoiding resonance zones and significantly improving low-frequency noise control.
2. Anlijing's Customized Process Standards:
· Structure: 4-6mm thick steel plate welded frame, with 8-14# steel mesh inside to enhance crack resistance.
· Filling: C30 high-strength concrete pouring to ensure overall rigidity and damping properties.
· Surface: The base and all exposed steel components are treated with anti-rust paint for durability and aesthetics.
Product Delivery Information
· Product Type: Non-standard customized product.
· Dimensions: Precisely matched according to the on-site installation space and equipment dimensions.
· Applicable Scenarios: Areas with high noise reduction requirements, such as home bedrooms, studies, hospitals, and recording studios.
