射流泵是由喷咀1,喉管(即混合室)2,扩散管3与喉管入口(即吸入室)4等四个主要零件构成。如图Ib所示,当有压工作液体经过喷咀1,以高速射出时,在吸入室内形成低压区,被吸流体进入吸入室并与工作射流在喉管内混合,依靠液体的紊动扩散作
Jet pump is composed of nozzle 1, throat (ie, mixing chamber) 2, diffuser 3 and throat inlet (ie, suction chamber) 4 and other four major components. As shown in Fig. Ib, when a pressurized working fluid passes through the nozzle 1 and emerges at a high speed, a low-pressure zone is formed in the suction chamber, the fluid to be suctioned enters the suction chamber and mixes with the working jet in the throat,
