Embodiment
Embodiment:
Among the embodiment shown in Figure 1; A kind of sewage transport pump improves structure, comprises motor 10 and retarder 20, at the helical rotor pump 30 of retarder 20 primes; Helical rotor pump 30 comprise elastomer stator 35 with twin-feed spiral cavity and in stator hole with the stainless steel single head spiral screw rod rotor 34 of its engagement; A side and retarder 20 at the pump feed end 31 that leans on helical rotor pump 30 link, and on pump feed end 31, are provided with water-adding pipe line interface 33, water-adding pipe line interface 33 external water charging systems.Drive single head spiral screw rod rotor 34 when stator 35 is made planet gyration at input shaft, the Seal cage 36 of stator 35 and at the uniform velocity axial motion of single head spiral screw rod rotor 34 engagements formation.Water charging system comprises adjusting control valve 362 (see figure 2)s that are connected with water-adding pipe line interface 33; Industry water pipeline 361 (see figure 2)s that are connected with adjusting control valve 362; Helical rotor pump 30 comprises pump discharge end 32, on 32 levels of pump discharge end, is provided with delivery gauge 37.Delivery gauge 37 discharging pipelines 321 are provided with discharging control valve 322, on feed end end pipeline 311, are provided with charging control valve 312 (see figure 2)s.
Working principle; When input shaft drives rotor 34 when stator 36 is made planet gyration; Just mesh continuously between stator and rotor and form Seal cage 36, do to these Seal cage 36 constancies of volume at the uniform velocity axial motion, working medium in the cesspool 40 such as sewage 41; Suck end 31 (seeing that A shows direction Fig. 1) stator-rotor pair of flowing through from stock and be delivered to stock output terminal 32 (seeing that B shows direction among Fig. 1), realize medium transport.From flow chart structural drawing 2, find out; The horizontal plane of fed sheet of a media such as sewage 41 is lower than the pump housing 30 (see figure 2)s; When pump just started, because of feed end end pipeline 311 (see figure 2)s are longer, the gas of internal memory continued to get into the pump housing; Be prone to cause the stator and the rotor dry grinding heating of transfer pump, thereby cause the damage of Sealing, fixed coupling unit and motor.And behind the access water charging system, be feed end water-adding pipe line interface 33 (see figure 1)s that industry water pipeline 361 (see figure 2)s are connected to pump, control valve 362 (see figure 2)s are set on pipeline, control valve 362 also can adopt manual control certainly.Before transfer pump starts; Earlier control valve 362 is opened; Make in the start-up course of transfer pump, have all the time pressure be the industry water of 0.5MPa as the moisturizing in the pump startup process, sewage is sucked in the pump chamber continuously in cesspool, pump discharge pressure is stable to rated pressure; Delivery gauge 37 (see figure 2)s are closed moisturizing line hand control valve, pump stable operation after showing pressure stability.
