As a low-speed, high-torque hydraulic actuator, the Motor Orbital OMR 80 is widely used in agricultural machinery, construction equipment, and other fields. Its operational stability directly impacts equipment efficiency. Excessive noise is not only disruptive but may also signal a malfunction. Ignoring it long-term can accelerate failure. However, there's no need to panic—follow these simple steps to troubleshoot and resolve the issue.
1. Defining Noise
First, understand what constitutes normal noise. During normal operation, the Motor Orbital OMR 80 produces a steady sound typically not exceeding 75 decibels. If the noise suddenly increases, or if you hear a shrill grinding or knocking sound accompanied by loss of motor power and machine vibration, shut down the machine immediately for inspection.
2. Causes of Noise Generation
Noise issues typically stem from three main categories:
① Hydraulic system problems, the most common cause. For instance, low oil levels in the tank allow air to enter the oil, causing the motor to emit abnormal sounds and visible bubbles in the oil. Using incorrect hydraulic fluid or contaminated oil also amplifies noise, with dirty oil appearing cloudy and containing impurities. Unstable system pressure can also impact the motor and generate noise.
② Internal motor issues. For instance, worn stator or rotor components produce metallic grinding sounds. Malfunctioning or jammed oil distribution parts cause not only noise but also fluctuating rotational speeds. Worn output shaft bearings without lubrication generate noise and vibration.
③ Improper installation and maintenance. Misaligned couplings between the motor and equipment can cause the motor to shake, amplifying noise. Loose mounting screws allow body vibration to increase noise levels. Prolonged lack of bearing lubrication leads to part wear and noise generation.
3. Solutions
First, inspect the hydraulic system. If oil levels are low, top up with appropriate anti-wear hydraulic oil. If the oil is dirty, replace it and clean the reservoir while you're at it. Check the hose fittings—tighten them or replace seals if air leaks occur. For unstable pressure, have a technician adjust the valves.
Next, examine installation and maintenance: Tighten loose screws per the manual. If the coupling is misaligned, have a technician adjust it. If noise persists after self-troubleshooting, internal motor components may be damaged—do not attempt disassembly. Contact professional maintenance personnel.
