![]() ![]() It is suitable to use the ejector at locations with sufficient working substance for device powering. Upon agreement, the injector can be made of special refractory steels and materials based on nickel titanium alloys, or tantalum. ![]() The body of the ejector can be cast, machined from a forge, or it is welded from bent centring. Wafer type design has advantage of easy replacement of ejector in case of eventual modification of technological parameters as well as better access for servicing. The weld insertion in the pipe has advantages such as material and mass savings on the flanges as well as minimization of leakage at the flange joints. Then admixture of working and suctioned substance with the steady pressure and velocity profile leaves the ejector. In case of subcritical flow, the mixing chamber has a shape of a cylinder and in case of supercritical flow it is tapered to slow down the flow.Īt the inlet of the divergent section (expanding channel) there must be subcritical flow according to Huguenot theorem, so that compression (i.e. Thanks to that there is a negative pressure formed in the suction chamber and it begins to suck-in the secondary (driven) liquid.Īt the outlet of the suction chamber of the nozzle the admixture of substances has the same pressure but different velocity profile, that is to be conditioned in the mixing chamber. Due to expansion in the nozzle the pressure is dropped and the velocity of the primary liquid is increased.
