HYDRAULIC PUMP CONTROL SYSTEM OF CONSTRUCTION EQUIPMENT, CAPABLE OF CONTROLLING A HYDRAULIC PUMP FOR SUPPLYING WORKING FLUID TO A BRAKING DEVICE AND A FAN MOTOR

摘要

PURPOSE: A hydraulic pump control system of construction equipment is provided to improve the safety of a vehicle by compressing the pressure of a braking device within a short time.;CONSTITUTION: A hydraulic pump control system of construction equipment comprises a pressure sensor(40) and a controller(50). The pressure sensor senses the pressure of the working fluid provided to the braking device(P1,P2). The controller controls the output flux of a pump(P) using one of a temperature control mode and a pressure control mode. The temperature control mode controls the discharge rate of the pump according to the temperature of the cooling fluid cooled by a fan(11). The pressure control mode controls the output flux of the pump according to the pressure detected by the pressure sensor.;COPYRIGHT KIPO 2010
