Product Description
Failure Modes and Preventive Strategies of Hydraulic System Filter Elements
■ In-depth analysis of failure mechanism
Particle contamination: Through SEM electron microscopy observation, it was found that 20-50μm metal abrasive particles are the main cause of wear in plunger pumps (accounting for 67%).
Water emulsification: When the water content exceeds 300ppm, the precipitation rate of additives increases by 3.2 times (verified by ASTM D6304 standard).
High-temperature oxidation: For every 10℃ increase above 85℃, the degradation rate of cellulose in filter paper grows exponentially
■ Empirical Prevention Plan A comparative test of a mine fleet shows:
The filter element replacement cycle and pump maintenance rate for traditional single-stage filtration are 23% after 500 hours, and for three-stage filtration systems, they are 8% after 1500 hours
