Abstract

The present invention provides a time-based power boost control system. A fluid source supplies fluid. A relief device relieves pressure of the fluid supplied by the fluid source when the pressure ofthe fluid exceeds a relief pressure level. A control device controls the relief device. When a boost mode in which at least a first level of pressure and a second level of pressure, higher than the first level of pressure, are allowed to be selectively used as the relief pressure level is active, a length of a boost-on time in which the second level of pressure is used as the relief pressure levelis shorter than a preset maximum boost-on time limit, and a length of a succeeding boost-off time succeeding the boost-on time in which the first level of pressure is used as the relief pressure level is equal to or longer than a preset minimum boost-off time limit.

Description

technical field [0001] The present disclosure relates to a power boost control system, and more particularly, the present disclosure relates to a time-based boost control system for performing power boost on / off control based on time. Background technique [0002] Various machines that utilize pressurized fluid to generate power are used on construction sites, in various industrial fields, and the like. For example, such machines supply pressurized fluid to actuators, which in turn utilize the pressure of the fluid to work. Since the pressure of the fluid inevitably changes during operation, when the pressure of the fluid rises too high, components to which the fluid pressure is applied may be damaged. Accordingly, there is provided a pressure relief device, such as a pressure relief valve, for preventing respective constitutional devices from being damaged by releasing the pressure of fluid that has increased to a level equal to or greater than a predetermined pressure amo...
