HYDRUALIC SYSTEM FOR CONSTRUCTION MACHINERY

摘要

PURPOSE: A hydraulic system for construction equipment is provided to improve working speed because the maximum flow rate of a pump can be discharged according to the operation rate of an operational part. CONSTITUTION: A hydraulic system for construction equipment comprises a pump pressure sensor(11), a swash plate tilting angle adjusting unit(30), and a control part(40). The pump pressure sensor detects the discharged pressure of a pump(10). The swash plate tilting angle adjusting unit controls the discharged flow rate of the pump. The control part controls the swash plate tilting angle adjusting unit to increase the operation rate of an operational part(20).
