Hydraulic pump components, leveraging their energy conversion properties, offer differentiated application solutions across various industries. The following is an analysis of typical industry applications:
1. Construction Machinery
Excavator Hydraulic System
Axial piston pumps use a swash plate to regulate flow and, in conjunction with a multi-way valve, provide precise boom control, achieving pressures exceeding 35 MPa.
Radial piston pumps are used in ultra-high-pressure applications (such as breakers), and their star-shaped piston arrangement can withstand transient impact loads.
Crane Power Unit
A gear pump assembly serves as an auxiliary pump to provide pilot oil pressure, while the main pump utilizes a variable displacement piston pump for stepless speed regulation.
2. Energy and Power Industry
Substation Maintenance Equipment
Portable piston pumps (such as Enerpac) SC series) with integrated lithium battery, achieving 73MPa high-pressure output for cable crimping operations.
Quick-plug oil pipe interface design supports field repairs.
Coal mine hydraulic supports.
Horizontal multi-plunger pumps provide emulsions, and a special sealing structure adapts to high-dust environments underground.
3. Special Environment Applications.
Off-grid areas: PVC hydraulic circulation pumps achieve self-sufficient hydraulic delivery through their physical structure, suitable for irrigation in remote areas.
Marine systems: Progressive cavity pump components are resistant to seawater corrosion and provide stable steering gear hydraulic power.
Adaptive solutions for different industries reflect the modular nature of hydraulic pump components. For example, construction machinery prioritizes high-pressure durability, while the power industry prioritizes portability and integration.
