**Haosail
Wheel Balancer Technical Manual**
**I. Working Principle**
The Haosail
wheel balancer employs centrifugal force detection technology to achieve dynamic tire balancing through a precision sensor system:
1. **Core Mechanism**
- Motor drives the rotor (tire assembly) at high speed
- High-accuracy sensors capture vibration displacement of the support frame
- Control unit performs signal amplification and filtering
- Microcontroller calculates counterweight solution
2. **Technical Background**
Due to manufacturing tolerances, wheel-tire assemblies exhibit uneven mass distribution. At speeds exceeding 100 km/h, dynamic imbalance occurs, causing steering wheel vibration and safety hazards. This equipment corrects imbalance through counterweight compensation.
**II. Recommended Applications**
Balancing is recommended in these scenarios:
1. After tire replacement (mandatory procedure)
2. When high-speed vibration occurs (>100 km/h)
3. Following tire repairs (assembly relationship changes)
4. During routine maintenance (recommended every 20,000 km)
**III. Selection Guide**
Key parameters for selection:
1. **Compatibility Range**
- Rim diameter: 14-24 inches (customizable)
- Tire width: 165-355mm
- Max load capacity: 50kg (compact models)/150kg (heavy-duty models)
2. **Optional Features**
□ Protective cover (prevents debris scattering)
□ Smart sensor (auto start/stop when cover opens)
□ Laser positioning system (counterweight guidance)
□ Vehicle database (auto parameter matching)

Wheel balancer Standard Operating Procedure**
**(A)
Wheel balancer Preparation**
1. **Site Requirements**
- Solid level surface (≤3° inclination)
- Stable power supply (220V±10%)
2. **Safety Check**
- Verify all fasteners are secure
- Test emergency stop function
**(B) Operation Steps**
1. **Power On & Warm-up**
- 3-minute idle operation
- System self-diagnosis (error code display)
2. **
Wheel balancer Parameter Setup**
- Enter tire specification (e.g. 195/55R15)
- Measure rim parameters:
• 1st knob: Flange distance measurement
• 2nd knob: Rim width determination
• Keypad: Input rim diameter (inches)
3. **Balancing Test**
- Initiate rotation (MAX 200 RPM)
- Auto-display:
▸ Imbalance amount (grams)
▸ Counterweight position (clock orientation)
4. **Correction**
- Add weights as indicated
- Two-point correction (12/6 o'clock positions)
- Tolerance ≤5g
**(C) Completion**
1. **Data Recording**
- Print test report
- Store historical data
2. **
Wheel balancers Maintenance**
- Daily: Clean sensor probes
- Weekly: Lubricate transmission components
- Monthly: Level calibration
**V. Important Notes**
1. **Safety Protocols**
- Safety goggles required
- Never touch rotating parts
- Emergency stop for abnormal vibrations
2. **Accuracy Assurance**
- Ambient temperature: 15-35°C
- Avoid strong EMI
- Regular calibration with reference wheel
