Component Specifications

Definition
Mounting flanges are specialized structural components designed to interface between a refrigerator compressor and its mounting bracket. They serve as critical connection points that transfer operational loads while dampening vibrations through engineered geometry and material properties. These flanges typically feature bolt patterns, alignment features, and vibration-damping surfaces that maintain compressor positioning within specified tolerances throughout thermal cycles and mechanical stress.
Working Principle
Mounting flanges operate on principles of mechanical fastening and vibration isolation. They create a rigid yet dampened connection between the compressor and bracket through: 1) Distributed load transfer across multiple bolt points, 2) Material elasticity that absorbs high-frequency vibrations, 3) Geometric design that prevents resonance amplification, and 4) Surface treatments that minimize fretting corrosion at contact points.
Materials
Cold-rolled steel (CRS) ASTM A366, Aluminum 6061-T6, or powder-coated steel with rubber isolation pads. Typical specifications include: thickness 3-5mm, hardness 70-90 HRB for steel or 60-80 HB for aluminum, corrosion resistance per ASTM B117 salt spray test (500+ hours).

Frequently Asked Questions

What are the critical tolerances for mounting flange installation?

Critical tolerances include: bolt hole positional tolerance ±0.2mm, flatness tolerance 0.1mm across surface, parallelism tolerance 0.15mm relative to mounting surface. These ensure proper compressor alignment and prevent premature bearing wear.

How do mounting flanges reduce compressor vibration transmission?

Through three mechanisms: 1) Material damping properties that convert vibrational energy to heat, 2) Geometric design that breaks resonant frequency paths, 3) Interface pads that provide additional isolation. Properly designed flanges can reduce vibration transmission by 70-85%.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
