Preizkušanje črpalk preko LIN komunikacije

HVALA, MATIC (author), Vončina, Danjel (mentor)

Trendi razvoja črpalk so usmerjeni v doseganje višjih vrtilnih hitrosti in tlakov pri manjšem volumnu črpalke. COR TMC je vrsta zobniške črpalke, ki jo poganja BLDC motor in se vse bolj uveljavlja na trgu za uporabo v različnih aplikacijah. Diplomsko delo opisuje razvoj LabVIEW programa za upravljanje vrtilne hitrosti in smeri vrtenja črpalke preko LIN komunikacijskega protokola. Predstavljene so teoretične lastnosti zobniških črpalk, delovanje BLDC motorja in teoretične osnove komunikacije LIN, katera je bila uporabljena za komuniciranje med strojno opremo podjetja National Instruments in mikrokrmilnikom Infineon TLE-9879, ki preko 3-faznega mostičnega pretvornika krmili izbrani motor črpalke. S pomočjo programskega paketa XNET v okolju LabVIEW je bil izdelan program, ki uporabniku omogoča krmiljenje črpalke in beleži parametre o njenem delovanju. V drugem delu naloge je opisana izdelava programa in preizkus njegove funkcionalnosti. Program bo uporabljen za izdelavo testnega mesta za testiranje in validacijo črpalk.

• Title: Pumps testing via LIN communication

Abstract

The trends in development of pumps are aimed in achieving higher rotation speeds and pressures with a smaller pump volume. COR TMC is a type of BLDC driven gear pump that is gaining ground in the market for use in a variety of different applications. The thesis describes development of a LabVIEW program for controlling rotation speed and direction of the pump via LIN communication protocol. Theoretical part of the thesis presents characteristics of gear pumps, operation of BLDC motor and theoretical basis of LIN communication which was used to communicate between National Instruments hardware and Infineon TLE-9879 microcontroller, which controls the selected pump with 3-phase bridge circuit. With the help of the XNET software package in the LabVIEW environment, a program was created that allows user to control the pump and record parameters of its operation. Development, operation and testing of the program are presented in the second part of the assignment. In the future the program will be used for the purpose of building a test site for testing and validating pumps.
