Why is there erosion on the barrel ports and port plate of my Denison Hydraulics P30S?
Erosion on barrel ports and the port plate of your Denison Hydraulics Water Pump is caused by air in the fluid, leading to cavitation.
Why is my Denison Hydraulics Water Pump so noisy?
If your Denison Hydraulics Water Pump is noisy, it could be due to several reasons: * Air in the fluid: This can be caused by a leak in the suction line, low fluid level, turbulent fluid return lines above the fluid level, gas leak from accumulator, excessive pressure drop in the inlet line from a pressurized reservoir or a suction line strainer acting as an air trap. * Cavitation in the pump or motor rotating group: This might be due to fluid that is too cold, too viscous, or too heavy; shaft speed that is too high; a suction line that is too small or collapsed; a suction strainer that is too small, too fine, or too dirty; high operating altitude; boost or replenishment pressure that is too low; or replenishment flow that is too small for dynamic conditions. * Misaligned shaft: Thi...
What causes high wear in my Denison Hydraulics P30S & Motor?
High wear in your Denison Hydraulics Water Pump & Motor can stem from several factors: * Excessive loads or contaminant particles in the fluid: Reduce pressure settings and speed. Ensure proper filter maintenance, avoid filters that are too coarse, prevent the introduction of dirty fluid to the system, maintain proper reservoir openings and breather, and ensure proper line replacement. * Improper fluid: The fluid might be too thin or thick for the operating temperatures, experiencing breakdown with time, temperature, or shearing effects, containing incorrect additives in new fluid, or suffering destruction of additive effectiveness with chemical aging. * Improper repair: This involves the use of incorrect parts, procedures, dimensions, or finishes. * Unwanted water in fluid: Check...
What causes pressure shocks in a Denison Hydraulics P30S Water Pump?
Pressure shocks in your Denison Hydraulics Water Pump can arise from: * Cogging load: Consider mechanical aspects. * Worn components: This includes worn relief valves and compensators, which require repairs. * Check valve issues: Slow response in check valves necessitates replacement or relocation. * Servo pressure: Servo pressure being too low to maintain firm control requires increased pressure and a check of the pressure drop through the servo filter. * Excessive energy or capacitance: Excessive decompression energy rates require improved decompression control, and excessive line capacitance (line volume, line stretch, accumulator effects) requires reduced line size or lengths, or elimination of hose. * Barrel blow-off: Re-check pump hold-down, rotating group, and drain pre...
