Konstrukční návrh ejektoru voda-voda a metod sloužících k optimalizaci pracovního procesu stroje

Abstract

This master thesis deals with design of the water – water type ejector and optimilization of the working process. At the beginning is inclusion of jet pumps in terms of energy machines. Every part of the ejector is described after inclusion of the jet pumps. Working process is detailed described in the next subchapter. Description of the energy losses is on the end of the indroduction to jet pumps. Market survey is presented showing cases of using water – water type ejectors in the last theoretical chapter of the thesis. Design of the water – water type ejector is contain in the practical part of the thesis. The ejector is designed according to two methods. First, the ejector is designed according to the empirical method. The second method contains apllication of the Bernoulli´s equations. In the next part, two methods are compared with each other. Options of the regulation are using to optimilization of the working process. These methods of regulation are in the next chapter. Attached to this thesis is complete drawing documentation.
