Function of surge chamber
Březina, Michal ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
The thesis is focused on creation of the mathematical model for calculating the change of fluid volume and flow in surge tank and air chamber during the water hammer effect. The work also includes the derivation of the basic equations of hydrodynamics and the theory dealing with water hammer including the possibilities in protection of the pipeline system during this phenomenon.
Vane pump
Mach, Jiří ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
This work gives basic information about vane pumps, especially with unbalanced construction and vanes led by rotor. The first chapter generally gives an attention to pumps. There are described basic information, classification, advantages and disadvantages of the types, characteristics and calculation relations. The following chapters describe the vane pumps in the way of classification, description of function and calculation relations. There is also made a practical calculation of vane pump according to the assignment accompanied by CFD analysis.
Positive displacement pump design
Homola, Tomáš ; Jandourek, Pavel (referee) ; Klas, Roman (advisor)
The bachelor thesis is focused on positive displacement pump design.
