Title: Judgment Method for Cavitation Inception of Hydraulic Turbine by Combining Vibration Test and Pressure Pulsation Test
Inventor: JIANJUN FENG
IPC: G01L23/00
Filed: 2021-11-18
Abstract: The invention discloses a judgment method for cavitation inception of hydraulic turbine by combining vibration test and pressure pulsation test. By collecting vibration speed and pressure pulsation signals of a hydraulic turbine under different working conditions, a method forjudging 5 cavitation incipient by using the change of first-order differences AA,- and AB,- of amplitude of vibration speed and pressure pulsation signals along with cavitation coefficient 0 is proposed for the first time. When cavitation does not occur in the turbine, the first-order differences AA,- and AB,- between vibration speed and pressure pulsation signal amplitude increase slowly with the decrease of cavitation coefficient 0. After cavitation occurs, the amplitude of vibration speed and 10 pressure pulsation signal will be enhanced. Hence, the cavitation inception point can be found through the derivatives of the curve of the pressure pulsation and vibration amplitudes change rate.

Abstract: A film or filament made from a polymeric material comprising units of an ethylenic aromatic compound and units of at least one vinyl ester, vinyl alcohol, hydroxyalkyl vinyl ether or sulphide, or hydroxyalkyl ether in which the alkyl group is interrupted by one or more ether oxygen atoms, is cross-linked by treatment with hydrogen fluoride or mixture thereof with boron trifluoride as an alkylation catalyst, whereby the aromatic nuclei in the polymer are alkylated with the oxygen-containing monomer units.  The resulting crosslinked products may be used in textile applications and, after appropriate chemical treatment, as ion-exchange materials.  The polymers from which the films and filaments are made may be copolymers, graft polymers or blends of polymers.  The examples describe the cross-linking of filaments made from a polyvinyl acetate-styrene graft polymer and a partial hydrolysis product thereof, a polyvinyl acetate-vinyl toluene graft polymer, a polyvinyl stearate-styrene graft polymer, graft polymers of styrene on polyvinyl hydroxyethyl ether and sulphide and polyvinyl 2-hydroxypropyl ether, and blends of polyvinyl acetate and polystyrene.  Cross-linked filaments made from polyvinyl acetate-styrene graft polymers are given ion-exchange properties either by sulphonation or by chloromethylation, followed by animation.  Also described is the preparation of the above polymers and also copolymers of tertbutyl acrylate and hydroxyethyl vinyl ether and sulphide, and copolymers of vinyl stearate and ethyl acrylate and acrylamide, by aqueous emulsion polymerization in the product of a catalyst mixture consisting of ammonium persulphate, sodium hydrosulphite, tert.-butyl hydroperoxide and ferric sulphate. The preparation of polyvinyl acetate-polystyrene blends is described, either by mixing aqueous dispersions or benzene solutions of the two polymers.
