| Hydraulic energy efficiency optimization | ★★★☆☆ | load sensing pump |
3. Technical advantages of Sumitomo hydraulic pumps
1.load sensitive control: Automatically adjust flow output, reducing energy consumption by up to 15%;
2.Dual pump confluence technology: When the workload is large, the dual pumps supply oil cooperatively to increase the action speed;
3.Long life design: Using special coating plunger, the service life exceeds 8000 hours.
4. Maintenance suggestions
To ensure optimal performance of the hydraulic pump, please note:
• Replace hydraulic oil filter every 500 hours
• Regularly check the vibration value of the pump body (should be <4.5mm/s)
• Avoid long-term overload work (pressure > 10% of rated value)
5. Market dynamics and user feedback
According to recent e-commerce platform data, the price range of Sumitomo original hydraulic pump accessories is as follows:
| Model | Average market price (yuan) | Warranty period |
|---|---|---|
| HPV90 | 28,000-32,000 | 1 year |
| HPV110 | 35,000-42,000 | 1.5 years |
Users generally report that its noise control is better than similar products, but special tools are required for maintenance.
Summary: The high-performance hydraulic pump equipped on Sumitomo excavators is the key to its competitiveness. With the development of intelligence and electrification trends, more innovative hydraulic solutions may appear in the future.
