Description

恒功率待命自动控制轴向柱塞泵
技术领域：
本发明涉及一种柱塞泵。
背景技术：
传统的恒功率变量轴向柱塞泵，由伺服活塞、油缸、变量油泵等组成，能耗大。
发明内容：
本发明的目的在于提供一种结构合理，节能的恒功率待命自动控制轴向柱塞泵。
本发明的技术解决方案是：
一种恒功率待命自动控制轴向柱塞泵，包括恒功率变量装置，其特征是：恒功率变量装置与待命控制装置连接。
待命控制装置包括待命油缸，待命油缸的活塞杆与恒功率变量装置的伺服活塞顶杆相对设置，待命油缸的上腔与恒功率变量装置的油缸上腔相通，另有一个电磁阀和待命油缸与恒功率变量装置油缸之间的油路相接，在恒功率变量装置油缸下腔与伺服活塞之间设置有节流器。
本发明结构合理，在传统的恒功率变量控制的基础上，增加待命控制功能，待命控制时，系统接近零压零流量运转，待命控制D点接近压力-流量变量特性曲线原点；通过对电磁阀的控制，油泵可在恒功率曲线段上任意工况点与待命控制D工况点之间进行切换，电磁阀吸合时，实现待命控制功能，电磁阀断开时，实现泵的恒功率控制功能；由于本发明具有待命控制功能，系统节能、降耗，能通过机、电、液、行程等信号对油泵进行待命控制，实现液压机的过程循环控制，节能20％以上。
附图说明：
下面结合附图和实施例对本发明作进一步说明。
图1是本发明一个实施例的结构示图。
图2是本发明变量特性曲线。
具体实施方式：
一种恒功率待命自动控制轴向柱塞泵，包括恒功率变量装置，恒功率变量装置与待命控制装置连接。恒功率变量装置由伺服活塞1、油缸2、变量油泵3等组成。待命控制装置包括待命油缸4，待命油缸4的活塞杆与恒功率变量装置的伺服活塞1顶杆相对设置，待命油缸的上腔5与油缸2的上腔6相通，另有一个电磁阀7和待命油缸4与油缸2之间的油路相接，在油缸2下腔8与伺服活塞1之间设置有节流器9。
