Razvoj hidravličnega sistema za izravnavo teže zapiralne ploskve hitro tekočih spiralnih vrat

Mrak, Sebastjan (author), Majdič, Franc (mentor)

Delo temelji na zasnovi koncepta hidravličnega pogona vrat. Težo zapiralne ploskve se izravnava s primerno pred-polnjenim hidravličnim akumulatorjem. Pripravljen je matematični model preračuna hidravličnega akumulatorja kot komponente hidravličnega koncepta pogona spiralnih vrat za izravnavo teže zapiralne ploskve. Na podlagi rezultatov matematičnega modela so določeni nastavitveni parametri sistema. Poznavanje slednjih in razumevanje vpliva na dimenzioniranje hidravličnega akumulatorja, kot podsestava za izravnavo teže zapiralne ploskve, je ključnega pomena za optimalno delovanje vrat s hidravličnim konceptom pogona. V sklopu meritev smo preverili ustreznost matematičnega modela in ovrednotili koncept hidravličnega pogona z vidika zagotavljanja projektnih zahtev. Na podlagi rezultatov matematičnega modela in meritev so podane smernice nadaljnjega razvoja in izboljšave hidravličnega pogona spiralnih vrat.

• Title: Development of a hydraulic system to compensate the weight of the closing surface of a high-speed spiral door

Abstract

The work is based on the development of a concept for a hydraulic drive for a high-speed spiral door. The weight of the closing surface is to be balanced by an appropriately precharged hydraulic accumulator. A mathematical calculation model has been presented to properly design a hydraulic accumulator as a component to compensate the weight of the closing surface. The results of the mathematical model are used to determine the parameters for designing the system. Knowing which parameters and how they affect the design of the hydraulic accumulator as a subcomponent to compensate the weight of the closing surface is key to the optimal operation of doors driven by newly developed hydraulic system. As part of the measurements, the mathematical model is validated and the design of the hydraulic system is evaluated to ensure that the design requirements are met. Based on the results of the mathematical model and the measurements, guidelines are given for further development and improvement of the hydraulic drive of high-speed spiral doors.
