Abstract

The invention provides a novel centralized remote pressure control loop with DRG hydraulic pumps in parallel connection. The novel centralized remote pressure control loop comprises multiple oil supply subsystems in parallel connection and a main adjusting pipeline. Each oil supply subsystem comprises one DRG hydraulic pump, oil inlets of the DRG hydraulic pumps communicate with an oil tank through pipelines, and oil outlets of the DRG hydraulic pumps are connected with an oil supply pipeline. An adjusting oil port of each DRG hydraulic pump communicates with the main adjusting pipeline through a branch pipeline. A remote adjusting valve is arranged on the main adjusting pipeline and carries out pressure adjustment on each DRG hydraulic pump. According to the novel centralized remote pressure control loop with the DRG hydraulic pumps in parallel connection, adjusting oil ways of the oil supply subsystems are combined into one, the remote adjusting valve can be used for adjusting the DRG hydraulic pumps of all the oil supply subsystems, the pressure value of the DRG hydraulic pumps can be the same, and the problem that errors exist during independent adjustment is solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic systems, and in particular relates to a novel DRG hydraulic pump parallel centralized remote pressure control circuit. Background technique [0002] In modern steel rolling equipment, the hydraulic system has been widely used. The control of the thickness and width of the finished product is inseparable from the hydraulic control system. Therefore, a stable and reliable hydraulic system is a necessary condition for the normal operation of the rolling mill and the control of rolling precision. [0003] The hydraulic pump is the oil source provider of the entire hydraulic system and the core of the hydraulic system. The operation of the hydraulic pump is related to the use of the entire hydraulic system. DRG constant pressure variable plunger pump can adjust the pressure remotely, so the pressure regulating device can be set at a position that is easy to enter and exit, and is easy to operate, whi...
