D modeling can directly start with quickshape without the sketch. D curves, deisgners can add dimensions and constraints as the needs. And different types of curves can be easily got, including projection curves, intersection curves, silhouette curves, centerlines and so on. Besides editing tool and dimension & constraint tools, Various inspection tools can help deisngers to quickly create a well- define sketch, such as curve connectivity or overlap inquiry. These automation tools allow users to create fully- constrained sketches with a single command.

D especially with tools such as Quick Draw and Ready- sketch. D models can be directly save as CATIA V4/5 part or assembly file.

D images imported into sketch environment can be convert to lines, arcs or curves. For image file (jpg, tif, bmp), many work can be done in ZW3. Get up and running fast with Show- n- Tell 3.

Product Information (click on an item for details). Pivotal dimensions are calculated from specified operating parameters of working and suctioned liquid.Version comparison - ZWSOFT. 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.
