Common issues associated with hydraulic motors.
High temperatures can speed up the degradation of fluid within the pump, this can damage the internal seals and cause major problems within the system. The performance of cooling and circuit components is fundamental in ensuring the motor is running at an optimal temperature. Look out for a drop in pressure, this is a good indication that your machine is running at too hot of a temperature.
This is commonly caused by cavitation or aeration within the motor. Contamination of air within the fluid can expedite damage to the components of the structure by decreasing lubrication and increasing excess heat. By carefully listening to the machine when you are using it you should be able to pick up on abnormal or irregular noises.
Reduction or Reduced movement
Should be an instant warning sign and an indication of an issue with your motor. Loss of movement or speed is caused by a loss of flow. Loss of flow causes loss of pressure which effectively means a reduction in output. This can be caused by an external leakage such as a burst hose or an internal leakage within the pump, actuators or valves.
Water contamination is often caused by a build-up of condensation within the walls of the reservoir which holds the fluid. This can occur when the outside temperature changes from hot to cold. Hydraulic fluid can even freeze causing many performance issues.
is generally rare in this type of motor but in some cases when the machine is extremely overworked the machine will overheat. Overheating can be reduced by ensuring the appropriate oil viscosity is being used. Taking breaks whilst using the machine in situations where overuse might occur can also help to alleviate the potential of a problem caused by hydraulic motor over-exertion.
