METHOD OF DIAGNOSING FAIL OF AN ANGLE SENSOR OF A HYDRAULIC PUMP

摘要

According to a method to correct an angle sensor of a hydraulic pump, a required pressure of the hydraulic pump is calculated in accordance to a degree of manipulation of a manipulation unit of the hydraulic pump, the required pressure is compared with an actual pressure of a pressurized oil discharged from the hydraulic pump, and is determined that a squared angle sensor of the hydraulic pump is abnormal if a difference between the actual pressure and the required pressure is out of a preset allowable range. As such, a worker prevents oil loss of the hydraulic pump due to the abnormal angle sensor by repairing or replacing the determined angle sensor.
