供油泵
GYB密封型供油泵的优点：
1、GYB密封型供油泵输送液体平稳、无脉动、无搅拌、振动小、噪音低。
2、GYB密封型供油泵有很强的自吸性能，多相混输时，含气率不高于80%，含沙量不高于500g/m3.
3、GYB密封型供油泵外置轴承结构，采用独立润滑，可以输送各种非润滑性介质。
4、GYB密封型供油泵采用同步齿轮驱动，二转子之间不接触，即使短时间空转也无妨。
5、GYB密封型供油泵泵体带有加热套，可以输送各种清洁或含有固体小颗粒的低粘度或高粘度介质(一般颗粒直径小于0.12-0.2mm)
6、GYB密封型供油泵正确的选用材料，甚至可以输送很多有腐蚀性的介质。
7、双吸式结构，转子上没有轴向力。
8、轴端采用机械密封或波纹管机械密封，具有寿命长、泄漏少、适用范围广的特点。
GYB.W密封型供油泵性能范围
1、最高工作压力4.0MPa
2、流量范围 1～1000m3/h
3、温度范围-20～120℃
4、介质粘度 1～3000mm2/s，降低转速可达到106mm2/s
介质粘度对供油泵性能影响较大，泵的名义排量是指在特定粘度条件下的排量，为保证泵能在较高效率下工作，在试验不充分时，建议按下列粘度条件选择转速：
介质粘度cSt 转速r/min
<400 1500
400 ～1200 1000
1200～3600 750
对于粘度更高的介质，所应选用的转速和驱动电机功率，请与制造厂联系。
