查询词典 vacuum

Fourth, to avoid breaking material: Screw must not be allowed in the case of blanking operation, upon occurrence of the stator as dry friction of rubber, produces instant heat and burn, so good grinder, screw grille flow is a necessary condition for normal operation To this end, some screw pump body is also expected to stop off device installed, when there Fracture, because he has a self-priming screw pump function of the characteristics Chemical pumps of the body will produce a vacuum chamber, vacuum screw pump will stop operation.

四、避免断料：螺杆泵决不允许在断料的情形下运转，一经消防泵发生，橡胶定子由于干摩擦，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。

Screw must not be allowed to break at the expected operating circumstances, once happened, rubber stator do because of friction heat generated instantly burned, so, good grinder, screw grille flow are a necessary condition for the normal operation of one of For this reason, some screw pump was also installed devices break down material, when the expected happened when broken, because of the screw pump has self-priming function of its characteristics, the body will produce a vacuum chamber, vacuum devices will stop screw operation.

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。

Screw does not allow for the case of run-off materials, once occurred, rubber stator due to dry friction, the heat generated instantly burned, so grinder intact, grille flow is a necessary condition for the normal operation of pumps, one of To this end, some screw pump is also installed in the body break down plant material, as occurs when the material off, because he has a self-priming pumps feature the characteristics of the body will produce a vacuum chamber, vacuum devices will screw pump to stop operation.

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。
