Stainless steel gear pump never allowed to run in the case of broken material, once occurred, the rubber stator due to dry friction, instantaneous heat generated and burned, so the grinder intact grille is one of the necessary conditions for the normal operation of the screw pump, To this end, some stainless steel gear pump pump body is also installed in the broken down device, when there is a broken material, the stainless steel gear pump has a self-priming function of the characteristics of the cavity will produce a vacuum, the vacuum device will stop the stainless steel gear pump . Stainless steel gear pump is a positive displacement rotary pump, when the outlet end is blocked, the pressure will gradually increase, so that the pressure exceeds the predetermined value. At this time the motor load increased dramatically. Transmission machinery related parts load will exceed the design value, severe motor burn occurs, the transmission parts broken. In order to avoid damage to the stainless steel gear pump, usually at the outlet of the screw pump installed bypass relief valve to stabilize the outlet pressure to maintain the normal operation of the pump. Currently on the market more types of stainless steel gear pumps, relatively speaking, imports of stainless steel gear pump design, excellent material, but the higher prices, some services are not in place, parts prices, ordering long, may affect the production The normal operation.
