C4的第一阀口通过油管连接至油源, 第二阀口通过油管连接至第一泵送油缸 10的 无杆腔,控制口 D4通过油管连接至压力油。当第一无杆腔插装阀 C4处于关闭状态时, 控制口 D4与压力油相连通, 通过控制压力油的压力, 可以控制第一无杆腔插装阀 C4 的开闭, 从而控制油源与第一泵送油缸的无杆腔之间的通断。 当第一无杆腔插装阀 C4 处于开启状态时, 控制口 D4与压力油断开, 与油源连通。 第二无杆腔插装阀 C3包括第一阀口、 第二阀口以及控制口 D3。 第二无杆腔插装 阀 C3的第一阀口通过油管连接至油源, 第二阀口通过油管连接至第二泵送油缸 20的 无杆腔,控制口 D3通过油管连接至压力油。当第二无杆腔插装阀 C3处于关闭状态时, 控制口 D3与压力油相连通, 通过控制压力油的压力, 可以控制第二无杆腔插装阀 C3 的开闭, 从而控制油源与第二泵送油缸的无杆腔之间的通断。 当第二无杆腔插装阀 C3 处于工作状态时, 控制口 D3与压力油断开, 与油源连通。 第一有杆腔插装阀 C6包括第一阀口、 第二阀口以及控制口 D6。 第一有杆腔插装 阀 C6的第一阀口通过油管连接至油源, 第二阀口通过油管连接至第一泵送油缸 10的 有杆腔,控制口 D6通过油管连接至压力油。当第一有杆腔插装阀 C6处于关闭状态时, 控制口 D6与压力油相连通, 通过控制压力油的压力, 可以控制第一有杆腔插装阀 C6 的开闭, 从而控制油源与第一泵送油缸的有杆腔之间的通断。 当第一有杆腔插装阀 C6 处于工作状态时, 控制口 D6与压力油断开, 与油源连通。 第二有杆腔插装阀 C5包括第一阀口、 第二阀口以及控制口 D5。 第二有杆腔插装 阀 C5的第一阀口通过油管连接至油源, 第二阀口通过油管连接至第二泵送油缸 20的 有杆腔,控制口

一主阀块和固定设置在第二泵送油缸 20上的第二主阀块, 第一无杆腔插装阀 C4和第 一有杆腔插装阀 C6安装在第一主阀块内,第二无杆腔插装阀 C3和第二有杆腔插装阀 C5安装在第二主阀块内。 将主阀块 30分为两个, 然后将分别将四个插装阀按照相关 性分为两组,相关的两个插装阀设置在同一个主阀块内, 使得主阀块的结构更加简单, 加工更加容易, 且能够进一步地减小主阀块的体积。 有杆腔多通阀块设置在第一泵送油缸 10和第二泵送油缸 20的有杆腔端部, 包括 多个油路通道以及设置在有杆腔多通阀块内的有杆腔连通插装阀 C2,有杆腔连通插装 阀 C2通过设置在有杆腔多通阀块内的油路通道连通或断开第一泵送油缸 10和第二泵 送油缸 20的有杆腔之间的连接。由于直接将有杆腔多通阀块设置在两个泵送油缸的有 杆腔端部, 因此, 位于有杆腔多通阀块内的有杆腔连通插装阀 C2 也设置在两个泵送 油缸的有杆腔端部, 当两个泵送油缸的有杆腔需要连通时, 可以直接从端部的有杆腔 连通插装阀 C2处流通。 已有技术中有杆腔连通时, 液压油需要从第一泵送油缸 10的 有杆腔流出,然后通过油管流动至设置在泵送油缸的中部的主阀块 30上的有杆腔连通 插装阀 C2, 之后再通过油管流动至第二泵送油缸 20。 相比较而言, 本发明的泵送装 置, 在泵送油缸的有杆腔连通时, 大大缩短了两个有杆腔之间的油路长度, 且可以无 需通过油管进行连接, 相应地, 也大大缩短了有杆腔连通插装阀 C2和两个泵送油缸 有杆腔之间的油路长度, 流量流经管道的长度至少减少 40%, 相应的沿程压力损失至 少也降低 40%。 优选地, 有杆腔多通阀块与第一泵送油缸 10和第二泵送油缸 20的有杆腔的油口 直接连接, 而不通过油管进行连接。 将有杆腔多通阀块的油口直接与第一泵送油缸 10 和第二泵送油缸 20的有杆腔的油口连接,减少了液压油因为流道变径或者流动方向改 变而带来的局部压力损失, 避免了油管连接在液压系统中的不利影响, 提高了液压系 统的工作效率。 由于两个油缸的有杆腔通过集成在油缸有杆腔油口的插装阀块直接连 通, 不用通过有杆腔油管, 拐角数量不到现有技术中方案的一半, 并且整个连通插装 阀块流道没有变径, 此处的相应局部压力损失至少降低 50%。 无杆腔多通阀块设置在第一泵送油缸 10和第二泵送油缸 20的无杆腔端部, 包括 多个油路通道以及设置在无杆腔多通阀块内的无杆腔连通插装阀 Cl,无杆腔连通插装 阀 C1通过设置在无杆腔多通阀块内的油路通道连通或断开第一泵送油缸 10和第二泵 送油缸 20的无杆腔之间的连接。由于直接将无杆腔多通阀块设置在两个泵送油缸的无 杆腔端部, 因此, 位于无杆腔多通阀块内的无杆腔连通插装阀 C1 也设置在两个泵送 油缸的无杆腔端部, 当两个泵送油缸的无杆腔需要连通时, 可以直接从端部的无杆腔 连通插装阀 C1处流通。 已有技术中无杆腔连通时, 液压油需要从第一泵送油缸 10的 无杆腔流出,然后通过油管流动至设置在泵送油缸的中部的主阀块 30上的无杆腔连通 插装阀 Cl, 之后再通过油管流动至第二泵送油缸 20。 相比较而言, 本发明的泵送装 置, 在泵送油缸的无杆腔连通时, 大大缩短了两个无杆腔之间的油路长度, 且无需通 过油管进行连接, 也大大缩短了无杆腔连通插装阀和两个泵送油缸无杆腔之间的油路 长度, 流量流经管道的长度至少减少 40%, 相应的沿程压力损失至少也降低 40%。 优选地, 无杆腔多通阀块与第一泵送油缸 10和第二泵送油缸 20的无杆腔的油口 直接连接, 而不通过油管进行连接。 将无杆腔多通阀块的油口直接与与第一泵送油缸 10和第二泵送油缸 20的无杆腔的油口连接, 减少了液压油因为流道变径或者流动方 向改变而带来的局部压力损失, 避免了油管连接在液压系统中的不利影响, 提高了液 压系统的工作效率。 由于两个油缸的无杆腔通过集成在油缸无杆腔油口的插装阀块直 接连通, 且可以不用通过无杆腔油管, 拐角数量不到现无技术中方案的一半, 并且整 个连通插装阀块流道没无变径, 此处的相应局部压力损失至少降低 50%。

无杆腔多通阀块包括两端分别固定设置在 第一泵送油缸 10和第二泵送油缸 20的无杆腔端部的无杆腔连通插装阀块 40, 无杆腔 连通插装阀 C1固定设置在无杆腔连通插装阀块 40内。 无杆腔连通插装阀块 40为一 个一体成型的阀块, 直接与第一泵送油缸 10和第二泵送油缸 20的无杆腔端部的油口 相连通, 实现第一泵送油缸 10和第二泵送油缸 20的无杆腔的通断。 如图 6所示, 当泵送装置处于第一种工作状态时, 控制口 Dl、 D5、 D6连通通压 力油, 插装阀 Cl、 C5、 C6关闭, 控制口 D2、 D3、 D4通油箱, 插装阀 C2、 C3、 C4 开启, 此时 A 口压力油经第一无杆腔插装阀 C4、 第一泵送油缸无杆腔油管、 无杆腔 多通块进第一泵送油缸, 此时第一泵送油缸的活塞杆伸出, 该第一泵送油缸的有杆腔 内的液压油经有杆腔连通插装阀 C2进入第二泵送油缸有杆腔, 此时第二泵送油缸的 活塞杆缩回, 该第二泵送油缸的无杆腔内的液压油经无杆腔多通块、 第二泵送油缸无 杆腔油管、 第二无杆腔插装阀 C3到 B口, 并回流至油箱。 当 B口进油, 经上述油路, 第二泵送油缸的活塞杆伸出, 第一泵送油缸的活塞杆缩回, 如此循环进行低压泵送。 如图 7所示, 当泵送装置处于第二种工作状态时, 当控制口 D2、 D3、 D4连通压 力油, 插装阀 C2、 C3、 C4关闭, 控制口 Dl、 D5、 D6通油箱, 插装阀 Cl、 C5、 C6 开启, 此时 A口压力油经第一有杆腔插装阀 C6、 第一泵送油缸 10的有杆腔油管、 有 杆腔多通阀块进入第一泵送油缸 10的有杆腔, 此时第一泵送油缸 10的活塞杆缩回, 该第一泵送油缸 10的无杆腔内的液压油经无杆腔连通插装阀 C1进第二泵送油缸 20 的无杆腔, 此时第二泵送油缸

以及无杆腔连通插装阀和泵送油缸无杆腔之间的油 管长度, 降低了压力损失, 提高了工作效率。 通过将有杆腔连通插装阀和无杆腔连通 插装阀与其它插装阀分别用不同的阀块进行安装,降低了主阀块的重量以及加工难度, 减小了体积, 降低了成本。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
