3GCR70×2W21三螺杆泵、燃油输送泵、三螺杆泵
3GR螺杆泵的流量、压力在相同转速、粘度时近似呈直线关系，压力越高，流量越小。相同粘度、压力下，三3GR螺杆泵的流量与转速近似成正比。相同转速、粘度下，轴功率与压力近似成正比。统一粘度、压力下，轴功率与转速近似成正比。粘度增大时，流量和轴功率均增加，但因为其中关系较复杂，必要时可向专业职员咨询。只要选型得当，维护公道，三3GR螺杆泵就可保证令人满足的运行.
3GR screw pump flow, pressure at approximately the same speed, viscosity linear relationship, the higher the pressure, the flux is small. The same viscosity, pressure, flow and speed of three 3GR is approximately proportional to the screw pump. Same speed, viscosity,the shaft power and pressure is approximately proportional to the. Unified viscosity, pressure,shaft power and speed linearly proportional to. Viscosity increases, the flow and shaft power increased, but because of the relationship between them is more complicated, when necessary to consult a professional staff. In short, as long as the selection of appropriate, to maintain justice, three 3GR screw pump can ensure satisfactory.
3GR螺杆泵不打量可能有如下几个方面的原因：
3GR screw pump may not look there are some reasons:
吸入管路堵塞或漏气，应对吸入管路进行检查；
1, the suction pipeline blockage or leakage, deal with the suction line inspection;
螺杆与泵 套磨损，维修或更换零部件；
2, screw and pump wear, repair or replacement of parts;
安全阀失效，调整弹簧，或研磨修复阀瓣与阀座；
3, safety valve spring failure, adjustment, or repair the valve and valve seat grinding;
电机反转或转速不够，修理或更换电机。
4, the motor reverse or speed is not enough, repair or replace the motor.
二、3GR螺杆泵安全注意事项
Two, 3GR screw pump safety precautions
不要将光杆拉出驱动头顶部超过60厘米；
1, don't be driven out of the first rod at the top of more than 60 cm;
如需将转子拉出定子进行反冲洗时，在拉起光杆时必须确定全部工作人员离开一定距离，并没有任何工具（如扳手）留在光杆上，直到转子全部拉出定子；
2, such as the need to pull the stator rotor backwashing, the p
