YCB圆弧齿轮泵结构特点：本系列齿轮泵主要有齿轮、轴、泵体、泵盖、轴承套、轴端密封等组成;齿轮采用双圆弧正弦曲线齿形制造。它与渐开线齿轮相比的优点是齿轮啮合过程中齿廓面没有相对滑动，所以齿面无磨损，运转平稳，无困液现象，噪音低、寿命长、效率高；该泵摆脱了传统设计的束缚，使得齿轮泵在设计、生产和使用上进入了一个新的领域。
应用范围：在输油系统中可用作传输，增压泵；在燃油系统中可用作输送，加压，喷射的燃油泵；在液压传动系统中可用作提供液压动力的液压泵；在一切工业领域中，均可作润滑油泵用。
用途：YCB圆弧齿轮泵适用于输送不含固体颗粒和纤维，无腐蚀性，温度不高于80℃，粘度为5×10-6～1.5×10-3m2/s(5～1500cst)的润滑油或性质类似润滑油的其它液体以及用于液压传动系统。该泵设有安全阀作为超载保护，安全阀全回流压力为泵额定排出压力的1.5倍；也可在允许排出压力范围内根据实际需要另行调整；但注意本安全阀不能作减压阀长期工作，需要时可在管路上另行安装。轴端密封设计为两种形式，一种为机械密封，一种是填料密封，可根据具体使用情况和用户要求确定。从主轴外伸端向泵看，为顺时针旋转。
