A11VO95LR3DS/10R-NZD12N00R恒压泵

A11VO95LR3DS/10R-NZD12N00R恒压泵柱塞泵的工作原理

   柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点，被广泛应用于高压、大流量和流量需要调节的场合，诸如液压机、工程机械和船舶中。

   柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入;柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油。

：3%的电压不平衡产生约18%的温升。保护电动机不出现相间不平衡的措施与缺相时采取的措施相同。温度保护排气温度：排气温度过高导致制冷剂分解，绝缘材料的老化，润滑油结碳，气阀损坏，还会使毛细管和干燥过滤器堵塞。保护方法主要是用温控器感应排气温度，温控器应安放靠近排气口处，排气温度过高时，温控器动作，切断电路。若排气温度过高由热气旁通引起，则不应采用停机的方法，应采用喷液冷却。机壳温度：机壳温度会影响压缩机的寿命。压缩机耗油量大原因：轴承、油环、汽缸与活塞处间隙过大，增加了跑油量。排除：进行相应的检修或更换部件。轴承温度过高原因：油脏、油路被堵；供油不足；间隙太小；轴承偏磨或轴瓦拉毛。排除：清洗油路，换润滑油；充分供油；调整间隙；检修轴瓦。能量调节机构失灵原因：油压不够；油中含制冷剂液体；调节机构出油阀脏堵。排除：找出油压低原因，调整油压；对曲轴箱中的油预热时间长一些；对油路、油阀清洗，使油路畅通。吸气温度过高原因：制冷剂不足或泄漏；蒸发器内制冷剂不足；膨胀阀开度过小。排除：检漏（连接和焊缝处有油迹）和消除漏点，补充制冷剂；调整供液量；加大阀的开度使吸气温度比蒸发温度高1～15℃。吸气压力过高原因：制冷剂过量；热负荷过大；膨胀阀开度不当；感温包安装不牢；压缩机排量减少；油分离器回油失灵。排除：放出多余制冷剂；调整负荷；调整阀的开度；感温包重新包扎；检查排气阀片，并对其修复或更换；检查修复自动回油或暂用手动回油。
