3GR36×6AW2三螺杆泵、卧式三螺杆泵
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,* 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,* 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,*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.

3GR螺杆泵的细节使用注意
3GR screw pump with attention to details
三螺杆的流量与转速成线性关系,相对于低转速的螺杆泵,高转速的螺杆泵虽然能增加了流量和扬程,但功率明显增大,高转速加速了转子与定子间的磨耗,必定使螺杆泵过早失效,而且高转速螺杆泵的定转子长度很短,极易磨损,因而缩短了螺杆泵的使用寿命。
Three screw linear flow and speed, relative to the low speed of the screw pump, screw pumphigh speed can increase the flow and head, but significantly increased power, high-speedaccelerated between the rotor and the stator wear, premature failure will make screw pump,and high speed screw pump rotor length is very short, easy to wear, and thus shorten the life of the screw pump.
3GR螺杆泵决不允许在断料的情形下运转,一经发生,橡胶定子由于干磨擦,瞬间产生高温而烧坏,所以,粉碎机完好,格栅畅通是螺杆泵正常运转的必要条件之一,为此,有些螺杆泵还在泵身上安装了断料停机装置,当发生断料时,由于螺杆泵其有自吸功能的特性,腔体内会产生真空,真空装置会使螺杆泵停止运转。
3GR screw pump must not be allowed to operate in the cutting conditions, the occurrence,the rubber stator due to dry friction, instant high heat and burn out, so, grinder intact, grille unimpeded is one of the necessary conditions for the normal operation of the screw pump,therefore, some screw pump in pump body installed end feeding stop device, when cutting,due to its characteristics of screw pump self-priming function, will produce a vacuum chamber, a vacuum device causes the screw pump to stop running.
3GR螺杆泵是一种容积式回转泵,当出口端受阻以后,压力会逐渐升高,以至于超过预定的压力值。此时电机负荷急剧增加。传动机械相关零件的负载也会超出设计值,严重时会发生电机烧毁,传动零件断裂。为了避免螺杆泵损坏,一般会在3GR螺杆泵出口处安装旁通溢流阀,用以稳定出口压力,保持泵的正常运转。
3GR screw pump is a positive displacement rotary pumps, when the exit blocked, the pressure will gradually increase, so that the pressure exceeds a predetermined value. At this point a sharp increase in the motor load. Transmission machinery related parts of the loadwill exceed the design value, severe electrical burn occurs, transmission parts breakage.Screw in order to avoid damage, usually installed in the screw pump bypass relief valve 3GRat the outlet, the outlet pressure to stabilize, maintain the normal operation of the pump.
