Mainly used in hydraulic systems, construction machinery hydraulic motor vehicle aspects, such as excavators, hydraulic pump motor maintenance, loader, garbage vehicles, and so on. Also used in a variety of pumps, such as: high-pressure plunger pump, reverse osmosis pumps, injection pumps, large-scale high-pressure pump, injection pump, high pressure slurry pump, pump gas drilling atomization, pressure injection pump, high-pressure water gun, oil drilling pumps, diesel driven pump, the three high-pressure plunger pumps, mills and phosphorus removal pump, high pressure fire pumps, desulfurization and denitrification pumps, high pressure cleaning pumps, chemical pumps, and so on. 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 most of the requirements of the mechanical slow smooth start hydraulic motor installation, in particular as a crane When the lift motor starting, when the heavy lifting in the air for the second moment, because of the small motor output torque can not lift heavy weights and the emergence of the phenomenon of falling seriously affect the safety of Liyuan Hydraulic motor is lifting machinery The 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. Hydraulic motor testing, creating crystal factory direct hydraulic (certified), a hydraulic motor provided by the Jinan Jing Chong Hydraulic Machinery Co., Ltd ..
