The Rationalization of Production Part of Injection Pump
Havel, Marian ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This thesis focuses on the rationalization of the production process of plungers and elements of injection pumps in relation to improving the quality of the final products. Today’s technology, which mainly uses single-purpose machines where the production quality markedly depends on the abilities and activities of the operator, will replaced by modern machining centres and CNC machines for grinding all functional parts of the plungers, coupled with modern measuring devices. These production machines with the support of measuring devices will improve the productivity of production and the general quality of the produced components.
The application of high-speed water jet in civil engineering
Hudský, Petr ; Hela,, Rudolf (referee) ; Bodnárová, Lenka (advisor)
Bachelor thesis is focused on gathering available information about the use high-speed water jet in civil engineering The thesis describes types of water jets, used in industry, focusing in detail on the use in construction. Mentioned are also selected tools for rehabilitation. Was studied experimentally the influence of pressure water jets for various types of concrete, cutting depth, strength and pull-off test with the evaluation and comparison.
The Concept of In-line Injection Pump for 120 MPa Pressures
Tichý, Ondřej ; Štěpánek, Karel (referee) ; Dundálek, Radim (advisor)
This thesis provides an overall evaluation of the concept of inline injection pump for pressure 120 MPa. The name of this pump is "Mj" and it is a product of the Motorpal, a.s. company. This thesis also contains an analysis of the contact pressures between the cam lobe and the pumping element's roller tappet. This includes comparing three different shapes of the roller and their influence on the magnitude of contact pressures. Calculations of the plunger helix and of the fuel delivery's impact on the relative position of plunger are also present.
Hydraulic part of plunger pump adjustment for higher pressures
Dvořák, Petr ; Klas, Roman (referee) ; Habán, Vladimír (advisor)
First part of the master thesis is about displacement pump. Second part is about power plunger pumps. In the third part are equations for power plunger pumps. In the last part the strength calculation of the proposed hydraulic part of the plunger pump was performed using the finite element method in ANSYS. The screw fatigue life is also calculated here. At the end of this section, ANSYS Fluent flow calculation is performed in the suction valve area.
