Different analytical methods have their different characteristics and performance of the hydraulic motor testing, but have one thing in common, that they are generally controlled by comparison to analyze problems and explain the problem. It is through the same or a different period indicators compare various indicators of control was reflected in the number of how many, the quality of the pros and cons, the level of efficiency, the size of consumption, the pace of development, etc., in order to make identification, the result of decision provide conclusive evidence of information. Crane used high-pressure automatic control variable motor, its initial displacement of the smallest displacement, the output torque of the smallest and fastest speed, can not be artificially control the speed, it is difficult to meet the most stable mechanical slow start, in particular from a crane in a liter When the motor, when the heavy lifting in the air for the second moment, because the motor output torque is small hydraulic motor can not lift heavy weights and the emergence of the phenomenon of falling hydraulic motor repair, seriously affect the safety of the hydraulic motor is mounted, is lifting Machinery taboo. The use of a simple pilot pressure control, although the operator can easily be controlled motor speed, but it is difficult to accurately perceive the situation and make a quick motor load operation. In order to ensure the safety of the operator, only to motor slow work, but reduces the efficiency of machinery.
