Description

一种双泵供油的连续冲击增压系统
技术领域
本实用新型涉及液压传动与控制技术领域，具体是一种双泵供油的连续冲击增压系统及增压方法。
背景技术
传统的冲击增压系统一般采用蓄能器和单活塞杆增压缸形成间歇式冲击增压，即冲击增压之后需要将活塞缩回，经蓄能器再次充液后进行冲击，如此反复，因此无法实现连续无间断冲击增压。
往复式增压缸可以实现连续增压，但是当和蓄能器同时使用时仍旧无法实现连续无间断冲击。
发明内容
为克服往复式增压缸和蓄能器同时使用时无法实现连续无间断冲击的问题，本实用新型提供一种双泵供油的连续冲击增压系统及增压方法。
本实用新型采用的技术方案是：一种双泵供油的连续冲击增压系统，
包括往复式增压缸、左油泵和右油泵；
所述左油泵出油口连接有左单向阀Ⅰ和左溢流阀；
所述左单向阀Ⅰ另一端连接有左压力继电器、左截止阀Ⅰ、左插装阀；所述左截止阀Ⅰ另一端连接有左蓄能器；所述左插装阀弹簧腔连接有左两位三通电磁阀Ⅱ和左两位三通电磁阀Ⅲ；所述左两位三通电磁阀Ⅱ另一端连接左插装阀进油口，左两位三通电磁阀Ⅲ另一端连接油箱；所述左插装阀出油口连接往复式增压缸左大腔；
所述左溢流阀弹簧腔通过左两位两通电磁阀Ⅰ连接油箱；
所述右油泵出油口连接有右单向阀Ⅰ和右溢流阀；
所述右单向阀Ⅰ另一端连接有右压力继电器、右截止阀Ⅰ、右插装阀；所述右截止阀Ⅰ另一端连接有右蓄能器；所述右插装阀弹簧腔连接有右两位三通电磁阀Ⅱ和右两位三通电磁阀Ⅲ；所述右两位三通电磁阀Ⅱ另一端连接右插装阀进油口，右两位三通电磁阀Ⅲ另一端连接油箱；所述右插装阀出油口连接往复式增压缸右大腔；
所述右溢流阀弹簧腔通过右两位两通电磁阀Ⅰ连接油箱；
所述往复式增压缸左伸缩杆端设有左行程开关，往复式增压缸右伸缩杆端设有右行程开关；
所述往复式增压缸左小腔通过左单向阀Ⅱ连通往复式增压缸左大腔，往复式增压缸左小腔还通过左单向阀Ⅲ连通高压油出油管；往复式增压缸右小腔通过右单向阀Ⅱ连通往复式增压缸右大腔，往复式增压缸右小腔还通过右单向阀Ⅲ连通所述高压油出油管；
所述往复式增压缸左大腔连接有左外控内泄顺序阀，往复式增压缸右大腔连接有右外控内泄顺序阀；所述左插装阀出油口连接右外控内泄顺序阀控制口，右插装阀出油口连接左外控内泄顺序阀控制口。
进一步：所述左插装阀出油口通过左单向阀Ⅳ、左截止阀Ⅱ连接往复式增压缸左大腔；所述右插装阀出油口通过右单向阀Ⅳ、右截止阀Ⅱ连接往复式增压缸右大腔。
一种采用双泵供油的连续冲击增压系统的增压方法，
①调定左溢流阀、右溢流阀的压力；调定左压力继电器、右压力继电器的压力；调定左外控内泄顺序阀、右外控内泄顺序阀的压力；选择往复式增压缸的增压比；
②启动左油泵、右油泵，左两位两通电磁阀Ⅰ的电磁铁YA1、右两位两通电磁阀Ⅰ的电磁铁YA4得电；左两位两通电磁阀Ⅰ、右两位两通电磁阀Ⅰ处于断开状态；
左油泵压出的油液经左单向阀Ⅰ和左截止阀Ⅰ进入左蓄能器，左蓄能器内部压力逐渐上升；
右油泵压出的油液经右单向阀Ⅰ和右截止阀Ⅰ进入右蓄能器，右蓄能器内部压力逐渐上升；
③当左蓄能器、右蓄能器的充液压力达到左压力继电器、右压力继电器的调定压力时，左压力继电器、右压力继电器发出信号控制左两位两通电磁阀Ⅰ的电磁铁YA1、右两位两通电磁阀Ⅰ的电磁铁YA4失电；
左油泵出油口通过左溢流阀、左两位两通电磁阀Ⅰ连通油箱，左油泵卸荷；
右油泵出油口通过右溢流阀、右两位两通电磁阀Ⅰ连通油箱，右油泵卸荷；
④之后，通过系统计时器，在0.1s内发出信号控制左两位三通电磁阀Ⅱ的电磁铁YA2、左两位三通电磁阀Ⅲ的电磁铁YA3得电；左两位三通电磁阀Ⅱ处于断开状态，左两位三通电磁阀Ⅲ与油箱相通；
使得，左插装阀弹簧腔连通油箱，压力降为零，左插装阀上下腔形成压力差，压力差克服弹簧力使得左插装阀的阀芯开启；
⑤左插装阀开启后，左蓄能器中储存的高压油液快速释放进入往复式增压缸左大腔、左小腔；同时，高压油液进入右外控内泄顺序阀的控制口，右外控内泄顺序阀开启；
往复式增压缸右大腔的油液经过右外控内泄顺序阀回油箱，往复式增压缸右小腔内增压后的高压油经右单向阀Ⅱ、右单向阀Ⅲ输出，此时左边的左单向阀Ⅱ、左单向阀Ⅲ被关闭；
⑥当往复式增压缸的活塞移到右端时，压下右行程开关，使得左两位两通电磁阀Ⅰ的电磁铁YA1得电，左两位三通电磁阀Ⅱ的电磁铁YA2、左两位三通电磁阀Ⅲ的电磁铁YA3失电，右两位三通电磁阀Ⅱ的电磁铁YA5、右两位三通电磁阀Ⅲ的电磁铁YA6得电；
此时左插装阀关闭，左两位两通电磁阀Ⅰ处于断开状态，左油泵重新为左蓄能器充液；并且右两位三通电磁阀Ⅱ处于断开状态，右两位三通电磁阀Ⅲ与油箱相通，使得右插装阀上端连通油箱，压力降为零，右插装阀上下腔形成压力差，压力差克服弹簧力使得右插装阀的阀芯开启；
⑦右插装阀的开启后，右蓄能器中储存的高压油液快速释放进入往复式增压缸右大腔、右小腔；同时，高压油液进入左外控内泄顺序阀的控制口，左外控内泄顺序阀开启；
往复式增压缸左大腔的油液经过左外控内泄顺序阀回油箱，往复式增压缸左小腔内增压后的高压油经左单向阀Ⅱ、左单向阀Ⅲ输出，此时右边的右单向阀Ⅱ、右单向阀Ⅲ被关闭；
⑧当往复式增压缸的活塞移到左端时，压下左行程开关，使得右两位两通电磁阀Ⅰ的电磁铁YA4得电，右两位三通电磁阀Ⅱ的电磁铁YA5、右两位三通电磁阀Ⅲ的电磁铁YA6失电，左两位三通电磁阀Ⅱ的电磁铁YA2、左两位三通电磁阀Ⅲ电磁铁YA3得电；
此时右插装阀关闭，右两位两通电磁阀Ⅰ处于断开状态，右油泵重新为右蓄能器充液，并且左两位三通电磁阀Ⅱ处于断开状态，左两位三通电磁阀Ⅲ与油箱相通，使得左插装阀上端连通油箱，压力降为零，左插装阀上下腔形成压力差，压力差克服弹簧力使得左插装阀的阀芯开启。
其进一步是：循环执行步骤⑤、⑥、⑦、⑧，往复式增压缸两端交替输出高压油，配合左蓄能器、右蓄能器的冲击形成连续无间断冲击增压。
调定左溢流阀、右溢流阀的压力为10MPa；调定左压力继电器、右压力继电器的压力为9MPa；调定左外控内泄顺序阀、右外控内泄顺序阀的压力为5MPa；选择增压比为2的往复式增压缸。
与现有技术相比，本实用新型的有益效果是：实现了增压系统的无间断的冲击增压，可用于具有明显高压冲击过程的液压动力装置，如液压凿岩机等，在遇到高硬度岩层时，通过无间断连续高压冲击从而破坏岩石。

实施例二
一双泵供油的连续冲击增压方法，在上述实施例一的基础上，包括如下步骤。
①调定左溢流阀6.1、右溢流阀6.2的压力为10MPa；调定左压力继电器3.1、右压力继电器3.2的压力为9MPa；调定左外控内泄顺序阀13.1、右外控内泄顺序阀13.2的压力为5MPa；选择增压比为2的往复式增压缸11；
②启动左油泵1.1、右油泵1.2，左两位两通电磁阀Ⅰ7.1的电磁铁YA1、右两位两通电磁阀Ⅰ7.2的电磁铁YA4得电；左两位两通电磁阀Ⅰ7.1、右两位两通电磁阀Ⅰ7.2处于断开状态；
左油泵1.1压出的油液经左单向阀Ⅰ2.1和左截止阀Ⅰ4.1进入左蓄能器5.1，左蓄能器5.1内部压力逐渐上升；
右油泵1.2压出的油液经右单向阀Ⅰ2.2和右截止阀Ⅰ4.2进入右蓄能器5.2，右蓄能器5.2内部压力逐渐上升；
③当左蓄能器5.1、右蓄能器5.2的充液压力达到左压力继电器3.1、右压力继电器3.2的调定压力时，左压力继电器3.1、右压力继电器3.2发出信号控制左两位两通电磁阀Ⅰ7.1的电磁铁YA1、右两位两通电磁阀Ⅰ7.2的电磁铁YA4失电；
左油泵1.1出油口通过左溢流阀6.1、左两位两通电磁阀Ⅰ7.1连通油箱，左油泵1.1卸荷；
右油泵1.2出油口通过右溢流阀6.2、右两位两通电磁阀Ⅰ7.2连通油箱，右油泵1.2卸荷；
④之后，通过系统计时器，在0.1s内发出信号控制左两位三通电磁阀Ⅱ9.1的电磁铁YA2、左两位三通电磁阀Ⅲ10.1的电磁铁YA3得电；左两位三通电磁阀Ⅱ9.1处于断开状态，左两位三通电磁阀Ⅲ10.1与油箱16相通；
使得，左插装阀8.1弹簧腔连通油箱16，压力降为零，左插装阀8.1上下腔形成压力差，压力差克服弹簧力使得左插装阀8.1的阀芯开启；
⑤左插装阀8.1开启后，左蓄能器5.1中储存的高压油液快速释放进入往复式增压缸11左大腔、左小腔；同时，高压油液进入右外控内泄顺序阀13.2的控制口，右外控内泄顺序阀13.2开启；
往复式增压缸11右大腔的油液经过右外控内泄顺序阀13.2回油箱16，往复式增压缸11右小腔内增压后的高压油经右单向阀Ⅱ14.2、右单向阀Ⅲ15.2输出，此时左边的左单向阀Ⅱ14.1、左单向阀Ⅲ15.1被关闭；
⑥当往复式增压缸11的活塞移到右端时，压下右行程开关12.2，使得左两位两通电磁阀Ⅰ7.1的电磁铁YA1得电，左两位三通电磁阀Ⅱ9.1的电磁铁YA2、左两位三通电磁阀Ⅲ10.1的电磁铁YA3失电，右两位三通电磁阀Ⅱ9.2的电磁铁YA5、右两位三通电磁阀Ⅲ10.2的电磁铁YA6得电；
此时左插装阀8.1关闭，左两位两通电磁阀Ⅰ7.1处于断开状态，左油泵1.1重新为左蓄能器5.1充液；并且右两位三通电磁阀Ⅱ9.2处于断开状态，右两位三通电磁阀Ⅲ10.2与油箱16相通，使得右插装阀8.2上端连通油箱16，压力降为零，右插装阀8.2上下腔形成压力差，压力差克服弹簧力使得右插装阀8.2的阀芯开启；
⑦右插装阀8.2的开启后，右蓄能器5.2中储存的高压油液快速释放进入往复式增压缸11右大腔、右小腔；同时，高压油液进入左外控内泄顺序阀13.1的控制口，左外控内泄顺序阀13.1开启；
往复式增压缸11左大腔的油液经过左外控内泄顺序阀13.1回油箱16，往复式增压缸11左小腔内增压后的高压油经左单向阀Ⅱ14.1、左单向阀Ⅲ15.1输出，此时右边的右单向阀Ⅱ14.2、右单向阀Ⅲ15.2被关闭；
⑧当往复式增压缸11的活塞移到左端时，压下左行程开关12.1，使得右两位两通电磁阀Ⅰ7.2的电磁铁YA4得电，右两位三通电磁阀Ⅱ9.2的电磁铁YA5、右两位三通电磁阀Ⅲ10.2的电磁铁YA6失电，左两位三通电磁阀Ⅱ9.1的电磁铁YA2、左两位三通电磁阀Ⅲ10.1电磁铁YA3得电；
此时右插装阀8.2关闭，右两位两通电磁阀Ⅰ7.2处于断开状态，右油泵1.2重新为右蓄能器5.2充液，并且左两位三通电磁阀Ⅱ9.1处于断开状态，左两位三通电磁阀Ⅲ10.1与油箱16相通，使得左插装阀8.1上端连通油箱，压力降为零，左插装阀8.1上下腔形成压力差，压力差克服弹簧力使得左插装阀8.1的阀芯开启；
循环执行步骤⑤、⑥、⑦、⑧，往复式增压缸11两端交替输出高压油，配合左蓄能器5.1、右蓄能器5.2的冲击形成连续无间断冲击增压。
