KR Piston Hydraulic Pump: Detailed Introduction
I. Working Principle
The working principle of the KR piston hydraulic pump is similar to that of a typical axial piston pump. In an axial piston pump, the reciprocating motion direction of the pistons is parallel to the central axis of the cylinder block. When the pistons move outward within the cylinder block, the volume inside increases, creating a negative pressure that draws in hydraulic oil. Conversely, when the pistons move inward, the volume decreases, compressing the hydraulic oil and expelling it from the pump. This process is achieved through the precise cooperation between the pistons and the cylinder block, ensuring efficient and stable hydraulic output.
II. Structural Features
1. Pistons and Cylinder Block: The pistons and cylinder block of the KR piston hydraulic pump typically feature high-precision fitting to ensure sealing and volumetric efficiency. The pistons reciprocate within the cylinder block, changing the sealed volume to achieve oil suction and discharge.
2. Swashplate or Swash Axis: Some axial piston pumps utilize a swashplate or swash axis to drive the reciprocating motion of the pistons. The angle of the swashplate or swash axis can be adjusted to vary the piston stroke and pump displacement. This design endows the KR piston hydraulic pump with variable displacement adjustment capabilities, allowing it to adapt output flow and pressure according to actual demands.
3. Port Plate: The port plate is a crucial component in axial piston pumps, responsible for distributing the suctioned hydraulic oil to each piston chamber and collecting the discharged high-pressure oil at the outlet. The design of the port plate directly impacts the pump's efficiency and performance.
III. Performance Advantages
1. High Efficiency and Energy Savings: The KR piston hydraulic pump employs high-precision fitting and optimized flow path design, reducing energy losses and leakage, thereby enhancing volumetric and mechanical efficiency.
2. High Pressure Capability: Due to the precise cooperation between the pistons and cylinder block, as well as the swashplate or swash axis design, the KR piston hydraulic pump can withstand high operating pressures, meeting the demands of various high-pressure hydraulic systems.
3. Flexible Flow Adjustment: By adjusting the angle of the swashplate or swash axis, the pump's displacement can be conveniently changed, enabling stepless flow adjustment. This flexibility allows the KR piston hydraulic pump to adapt to different operating conditions.
4. Long Service Life: The KR piston hydraulic pump is constructed from high-quality materials and advanced manufacturing processes, ensuring durability and reliability. Under normal operating conditions, the pump has a long service life, reducing maintenance and replacement costs.
IV. Application Scenarios
The KR piston hydraulic pump is widely used in various applications requiring high-pressure, large-flow hydraulic systems, such as:
1. Construction Machinery: Hydraulic systems of excavators, loaders, cranes, and other construction equipment.
2. Metallurgical Machinery: Hydraulic systems of rolling mills, forging presses, and other metallurgical equipment.
3. Marine Machinery: Hydraulic systems of ships' steering gear and anchor winches.
4. Industrial Automation: Hydraulic transmission systems of various industrial automation equipment.
