Направляющая пружина головки насоса привода, НД 21,2 мм Caterpillar 5511130

The Drive Pump Head Pilot Spring is used in the internal structure of the drive pump to deliver a controlled preload and consistent force to the pilot valve or head assembly. It helps regulate hydraulic pressure and maintain the positioning of internal pump components under variable load and flow conditions. This spring ensures smooth pump function by dampening movement and absorbing shocks that occur during high-pressure hydraulic operation. By applying continuous tension, it contributes to the stability and responsiveness of the pump’s internal mechanism, supporting accurate pressure control and flow direction. Attributes:• Maintains stable preload in drive pump pilot assembly.• Supports smooth hydraulic pressure transitions.• Assists in aligning internal pump components.• Provides shock absorption during high-pressure flow.Applications: The Drive Pump Head Pilot Spring is used inside the head assembly of the drive pump in equipment to support the pilot mechanism, stabilize internal components, and regulate hydraulic pressure changes during operation.
