The Analysis For Rexroth Axial Piston Pump Common Breakdown:
1. Seal aging typically occurs from prolonged exposure to high temperatures, pressures, and deteriorated oil, leading to leakage and pressure loss that diminish overall performance. It is recommended to replace seals at regular intervals and use high wear-resistant materials. This axial piston pump must maintain excellent sealing integrity to ensure consistent, reliable operation and optimal hydraulic performance over time.

Hydraulic oil contamination is often caused by dust, foreign particles, or delayed oil replacement, which reduces lubrication efficiency and accelerates component wear, adversely affecting system performance. It is recommended to use high-quality oil, install proper filtration systems, and replace the oil on schedule. This hydraulic pump must operate with clean oil to maintain optimal efficiency and prolong service life.
3. Temperature sensor failure can occur from sensor aging, poor contact, or signal transmission issues, resulting in inaccurate temperature readings that disrupt the thermal control system and lead to overheating or overcooling. It is recommended to check sensor conditions regularly and replace any faulty sensors promptly. This piston pump relies on accurate temperature monitoring for safe, efficient operation.
