Split Barge Bottom Door Hydraulic Power Unit

Split Barge Bottom Door Hydraulic Power Unit

Description

The split barge bottom door hydraulic power unit is used to drive open-body cylinder and other special-purpose hydraulic cylinders. This hydraulic system is composed of hydraulic pump, control valve group, differential valve group, hydraulic oil cylinder pressure maintaining valve group, hydraulic oil cylinder overload valve group, hydraulic oil cylinder, etc. In order to ensure that the technical performance and functions of the oil cylinder can achieve the best results, the system is controlled by an open constant power pump, and the key components are imported valves. The system mainly consists of two (one working, one standby) 11kW motor driven hydraulic pump to provide pressure oil, and the corresponding hydraulic control valve drives the cylinder to open and close the body. In addition, the cylinders are equipped with valve blocks for pressure holding, overload, differential and anti-cavitation.
