Single screw pump, such as cognitive and introduction

1。 What is the single screw pump? Single screw pump belongs to a rotor type positive displacement pump, it is depend on the screw meshing with liner on the discharge and suction cavity to conveying liquid volume change. It is a kind of method of pressurized screw pump, a main working parts by bushing has a double helix cavity ( The stator) And in the stator cavity and its meshing single-head screw screw ( Rotor) Composition. 2. Single screw water pump working principle of single screw pump in our many petrochemical device application, it is a unique way to construct positive displacement pump, mainly composed of motor, gear box, transmission shaft and parts such as stator and rotor. Which is also called the screw rotor, pump running, screw driven by motor ( Rotor) In the stator ( Elastic sleeve) In rotary motion, the rotor ( Screw) And the stator ( Elastic sleeve) Formed a few without feeling sealed cavity, due to the rotation of the screw, sealing cavity along the axial direction from the suction end to the discharge end, continuously in the cavity by the suction flow to the discharge end. Screw pump rotor may be a root of, also can have two or three, only a single screw in the screw pump is also called the single screw pump, our company polyester device of the slurry pump is single screw pump. 3. Why can't we do turn when single screw pump start? Single screw pump you start without full of medium dry, rubber stator ( Drum set) Will be seriously damaged, so we in the slurry pump starts, you must first open the import EG flush valve and outlet valve, the pump body is full of EG, and then you can start at the lowest speed pump. 4. Why conveying slurry of single screw pump when the pump is going to stop, first close the inlet valve? Two pump for slurry pump is running at the same time, as spare, and because my company did not install the check valve, slurry pump, the exit if directly to stop the pump running, the material will be from another pump export backward into the pump has stopped, back into the, the slurry can drive the rotor reverse at the same time, on the one hand, cause the volatility of the feed rate of the esterification reaction kettle 1, on the other hand is also easy to cause the damage of the pump. So before the pump stop, must close the inlet valve, truncation slurry flow channel, import EG flush valve fully open pump at the same time, on the one hand, make the pump not idle, on the other hand can also be carried out on the pump body wash.
