Hydraulic control system for engineering machinery and engineering machinery
The invention relates to a hydraulic control system for engineering machinery and the engineering machinery. The hydraulic control system comprises a rotation subsystem, an air conditioner subsystem and a control valve set. The rotation subsystem is connected with a hydraulic oil way of the air conditioner subsystem in parallel, and the first hydraulic motor and the second hydraulic motor share the same hydraulic source. The control valve set is arranged between the hydraulic source and the rotation subsystem and between the hydraulic source and the air conditioner subsystem so that hydraulic oil provided by the hydraulic source can be independently supplied to the air conditioner subsystem, or the hydraulic oil provided by the hydraulic source can be supplied to the rotation subsystem and the air conditioner subsystem at the same time. And the hydraulic oil distributed to the air conditioning subsystem is constant in flow. Due to the fact that the same hydraulic source is used, and the air conditioner subsystem and the rotation subsystem are connected in parallel, the hydraulic control system can solve the problems that in the rotation process, due to starting and stopping of the air conditioner subsystem, rotation shaking is caused, and the comfort of an operator is affected. And the hydraulic control system disclosed by the invention has low requirement on arrangement space.
本公开涉及一种用于工程机械的液压控制系统及工程机械，液压控制系统包括回转子系统、空调子系统和控制阀组。回转子系统与空调子系统的液压油路并联，且第一液压马达和第二液压马达共用同一液压源。控制阀组设置在液压源与回转子系统、液压源与空调子系统之间，以使得液压源提供的液压油能够单独供给空调子系统，或者，以使得液压源提供的液压油同时供给回转子系统和空调子系统。分配给空调子系统的液压油为恒定流量。由于使用的是同一液压源，并使得空调子系统和回转子系统相互并联，本公开的液压控制系统能够解决在回转过程中由于空调子系统启闭而造成回转晃动和影响操作者舒适性的问题。并且本公开的液压控制系统对于布置空间的需求小。
