Analysis of Core Functions: Plunger Pump Bushings
Material Properties: Utilizes highly wear-resistant materials-such as ceramics or cemented carbides-to ensure structural integrity under high-pressure, high-frequency operating conditions.
Positioning Function: Closely envelops the plunger surface, minimizing frictional wear between metals through physical separation.
Sealing Mechanism: Employs a static sealing method, utilizing precision-machined clearances to prevent fluid leakage.
Plunger Pump
Typical Characteristics and Application Scenarios: Oil Seals
Elastic Structure: Combines rubber or synthetic materials with a metal framework to accommodate the dynamic deformation of rotating shafts.
Protection Focus: Provides bidirectional isolation, preventing lubricant leakage while blocking the ingress of dust and moisture into the bearing cavity.
Installation Standards: Requires strict adherence to shaft-diameter matching principles to ensure the seal lip exerts appropriate contact pressure against the moving component.
Synergistic Relationship Between the Two Sealing Components
Complementarity: Bushings address radial sealing for the plunger, while oil seals manage fluid boundary control.
Material Distinction: Bushings prioritize rigidity and wear resistance; oil seals rely on elastic recovery capabilities.
System Integration: Hydraulic pump design requires simultaneous consideration of installation space and functional coordination for both components.
