3GC100×2W21三螺杆泵、液压油输送泵
3GR螺杆泵以输送介质粘度和泵的规格确定转速范围:输送高粘度介质时,泵应选低转速,若粘度较低,相应可选择高转速:
3GR screw pump for conveying medium viscosity and pump specifications to determine thespeed range: the transport of high viscosity medium, the pump should be selected the low speed, if the viscosity is low, the corresponding choice of high speed:
1)介质粘度 〉20 ° E 时,对于大规格的3GR螺杆泵(主杆外径 60mm 以上),转速以 970rpm 或 720rpm 为宜,如果粘度更高(粘度>80 ° E )如粘胶液,可降低转速使用,推荐 200-500rpm
1 medium viscosity ') at 20 ° E, for the 3GR screw pump size (above the main rod diameter 60mm), the speed with 970rpm or 720rpm is appropriate, if higher viscosity (viscosity >80 ° E) such as viscose, can reduce speed to use, recommended 200-500rpm
2)对于小规格的3GR螺杆泵,介质粘度>20 ° E 时,转速以 1450rpm 或 970rpm 为宜,如果粘度更高(粘度>80 ° E ),可降低转速使用,推荐 300-600rpm ;由于泵的转速越高,在相同性能参数下,泵的体积就越小,但由于转速高,摩擦功率高,泵的磨损就大,寿命就短,如果输送介质的润滑性比较差或含有微量杂质,应选择较低转速,以使泵保持较长的寿命,推荐在 1450rpm 以下.
2) for the 3GR screw pump small size, medium viscosity >20 ° E, speed to 1450rpm or970rpm is appropriate, if higher viscosity (viscosity >80 ° E), can reduce the speed to use,recommended 300-600rpm; because of the higher speed of the pump, in the same performance parameters, the smaller size of the pump, but because of high speed, high power pump friction, wear and tear on the big, short life, if the transmission medium relatively poor lubrication or contain trace impurities, should choose a lower speed, so that the pump to maintain a longer life, recommend below 1450rpm.
