Description

Product overview: On the basis of in-depth study of foreign advanced technologies, our company has developed the 2w.w H bearing external double-suction double-screw multiphase hybrid pump and 2w. W twin screw pump according to the actual requirements of our current oil and gas mixture transportation, and produced them according to the standard gb11035-89 of Marine electric twin screw pump. Through the intermeshing of the main and driven screws in the pump body, as well as the cooperation of the screw and the pump body holes, a series of sealed cavities are formed in the pump body. When the screw rotates, these sealed cavities move forward continuously, pushing the liquid in the sealed cavity to the outlet for discharging, so as to realize the purpose of conveying liquid. Structural features: The 2w. W twin-screw pump adopts the double-suction structure. Both ends of the screw are in the same pressure chamber, and the axial force can be balanced by itself. The bearing at both ends is provided with an external mounting type, which is lubricated by lubricating oil (grease) separately, so that it is not affected by the conveying medium. Driven by a pair of synchronous gears, the cylinders between the screw teeth do not contact with each other, but leave a small gap. Impurities in the medium do not cause direct wear (except flushing) on the screw teeth. Except for some small displacement pumps (2w.w4.0 and below). In general, the pump body with inner flow valve, when the discharge pressure exceeds the rating, a certain protection. There are two directions on the pump body, one is horizontal.
