液压油泵与马达事故与维护（Hydraulic oil pump and motor accident and maintenance） Hydraulic pump and motor accident and maintenance 2011-09-19 18:04, hydraulic pump and oil motor will inevitably malfunction during use, and these faults can be divided into paroxysmal and wear faults. Among them, the wear fault often occurs in the later stage of the system, mainly because of the natural wear of the parts, and the damage to the system is mostly caused by the failure of the sealing material The hydraulic oil pump and the oil motor will inevitably break down in the course of using, and these faults can be divided into paroxysmal and wear faults. Among them, the late wear fault occurred in the system, mainly due to natural wear parts caused by the damage of the system caused the most of the performance of sealing material failure, actuator movement speed gradually slowed down, little effect; work early and mid and sudden failure often occurs in the system. Is mainly due to the managers in the use and maintenance according to the operation requirements and procedures were caused by the damage of the system caused most of the performance for the oil pump cylinder oil motor burning, serious accidents, damage, creeping phenomenon of hydraulic components hydraulic pipeline rupture, great impact. The frequency of these failures is closely related to the quality of daily use, maintenance and maintenance. In order to keep them in good working condition and long service life long, in addition to the daily maintenance and should establish a sound system of necessity, in order to reduce the wear fault later, should also maximize the prevention of sudden accident early and mid. 1, to ensure the normal state of system oil The problem of hydraulic oil has always been regarded as the chief cause of the failure of hydraulic system. Because of the limitation of space, it will not be repeated here. Only some typical problems will be explained. 1.1 oil viscosity should meet the requirements If the hydrau
