Decision inputs
- Cylinder pressure and pulsation level
- Packing allowable load
- Stroke frequency
- Maintenance interval
APPLICATION SOLUTION
Pumps & hydraulics live loading
Reciprocating pump plungers and high-pressure packing keep sealing load with disc spring live loading compensating wear; this entry page lists live loading decision points and verification methods.
ENGINEERING PROBLEM
Plunger reciprocation and pressure pulsation rapidly decay packing load, raising leakage and maintenance frequency.
BOUNDARY
This page describes a decision pattern and does not promise size or performance for another operating condition.
Solution pattern
- Disc spring live load assemblies keep constant clamping
- Reserve compensation travel for wear
- Control assembly by height with records
Key risks
- Overpressure damages packing
- Pulsation fatigue
- Solids abrasion
Verification plan
- Clamp force-displacement calibration
- Leakage and temperature monitoring
- Scheduled compensation records
