开式泵和闭式泵这个概念一般是针对斜盘式轴向柱塞泵的，尤其是对于闭式泵而言，好像据我所知目前只有斜盘式的，因为改变斜盘角度从正的最大角度到负的最大角度，斜盘惯性质量小，易于改变，反应快。\u003C\u002Fp>\n\u003Cp>　　8. 对于开式泵和闭式泵，其变量方式基本一样，都是靠改变斜盘角度来实现的，至于变量要求是根据不同工况而言，你所讲的压力补偿，负荷敏感这些变量要求，在开式泵和闭式泵都有应用，实际上是一个阀控的反馈系统。\u003C\u002Fp>\n\u003Cp>　　9. 大多数情况下，一般选用开式泵，因为在满足工况要求的前提下，经济性相对好些。在对油箱体积有明确要求的工况下，如行走机械，起重机械等，因为空间有限，就需要运用闭式泵，因为其省去了液压阀和一些管路，所以油箱体积相对减小。\u003C\u002Fp>\n\u003Cp>　　10. 开式系统是指液压泵从油箱吸油，油经各种控制阀后，驱动液压执行元件，回油再经过换向阀回油箱。这种系统结构较为简单，可以发挥油箱的散热、沉淀杂质作用，但因油液常与空气接触，使空气易于渗入系统，导致机构运动不平稳等后果。开式系统油箱大，油泵自吸性能好。\u003C\u002Fp>\n\u003Cp>　　11. 闭式系统中，液压泵的进油管直接与执行元件的回油管相连，工作液体在系统的管路中进行封闭循环。其结构紧凑，与空气接触机会少，空气不易渗入系统，故传动较平稳。工作机构的变速和换向*调节泵或马达的变量机构实现，避免了开式系统换向过程中所出现的液压冲击和能量损失。但闭式系统较开式系统复杂，因无油箱，油液的散热和过滤条件较差。\u003C\u002Fp>","[{\"name\":\"1614843980.jpg\",\"preview\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002F388f4243-de8a-4b22-9874-45f92ed0cb35.jpg\",\"size\":73117,\"thumbnail\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002F388f4243-de8a-4b22-9874-45f92ed0cb35.jpg\",\"url\":\"\u002Fimage\u002F2024\u002F07\u002F08\u002F388f4243-de8a-4b22-9874-45f92ed0cb35.jpg\"},{\"name\":\"1614844119.jpg\",\"preview\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002F8aae002d-6078-471a-87cf-e8c4fbdf29b6.jpg\",\"size\":65231,\"thumbnail\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002F8aae002d-6078-471a-87cf-e8c4fbdf29b6.jpg\",\"url\":\"\u002Fimage\u002F2024\u002F07\u002F08\u002F8aae002d-6078-471a-87cf-e8c4fbdf29b6.jpg\"},{\"name\":\"0ce94949898178d7d9d5d6324fbd57c.png\",\"preview\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002Fc187a470-f4bb-480a-a9df-3deebfb72b94.png\",\"size\":178332,\"thumbnail\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002Fc187a470-f4bb-480a-a9df-3deebfb72b94.png\",\"url\":\"\u002Fimage\u002F2024\u002F07\u002F08\u002Fc187a470-f4bb-480a-a9df-3deebfb72b94.png\"},{\"name\":\"1b4f2ebec3317949e700f4f7b5c69a3.png\",\"preview\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002F753fb9fa-e690-4b6c-8a40-e88ae1e7efa6.png\",\"size\":20774,\"thumbnail\":\"https:\u002F\u002Fzhht-images.oss-cn-beijing.aliyuncs.com\u002Fimage\u002F2024\u002F07\u002F08\u002F753fb9fa-e690-4b6c-8a40-e88ae1e7efa6.png\",\"url\":\"\u002Fimage\u002F2024\u002F07\u002F08\u002F753fb9fa-e690-4b6c-8a40-e88ae1e7efa6.png\"}]",{"createBy":6,"createTime":6,"updateBy":6,"updateTime":6,"remark":6,"scope":6,"id":8,"siteId":6,"slug":10,"name":11,"country":6,"images":6,"files":6,"subtitle":6,"description":6,"status":6,"isHot":6,"sort":6,"seoTitle":6,"seoDescription":6,"seoKeywords":6},{"createBy":6,"createTime":6,"updateBy":6,"updateTime":6,"remark":6,"scope":6,"id":186,"siteId":6,"parentId":6,"ancestors":6,"slug":194,"name":195,"images":6,"files":6,"subtitle":6,"isHot":6,"status":6,"sort":6,"seoTitle":6,"seoDescription":6,"seoKeywords":6},"141","柱塞泵",200,"查询成功"]
