Description
Предметом изобретени вл етс лопастной винт дл гидрометрической вертушки с горизонтальной осью.The subject of the invention is a propeller screw for a horizontal axis hydrometer.
Известные винты гидрометрических вертушек имеют винтовые или чашечные лопасти.Known screws hydrometric turntables have a screw or pan blade.
Гидрометрическа вертушка с чашечными лопаст ми в турбулент |ых нотока.х регистрирует продольную составл юш,ую скорости течени с преувеличением, а вертушка с винтовыми лопаст ми- с преуменьшением против действительной ее величины.A hydrometric turntable with cup-shaped blades in turbulent notoka.kh registers the longitudinal flow rate, exaggeration of its current velocity, and the turntable with screw blades minimizing its actual magnitude.
Предложенный лопастной винт дл гидрометрической вертушки свободен от этих недостатков, так как поверхности его лопастей выполнены в виде желоба, изогнутого по винтовой линии.The proposed blade screw for a hydrometric spinner is free from these drawbacks, since the surfaces of its blades are designed as a groove curved along a helical line.
Така конструкци лопастного винта coBMeHj,aeT элементы рабочей части винтового и чашечного роторов и обеспечивает повышенную точность измерени продольной составл юп .1,ей скорости в турбулентных потоках.Such a blade coBMeHj screw design, aeT elements of the working part of the screw and cup rotors and provides increased accuracy of measurement of the longitudinal component Jup. 1, its velocity in turbulent flows.
На чертеже дан обший вид вдоль оси винта, его продольный и поперечный разрезы.The drawing shows a general view along the axis of the screw, its longitudinal and transverse cuts.
Винт имеет три лопасти 1, выполненные в виде одной детали с втулкой 2, насаженной на ось счетного механизма гидрометрической вертушки.The screw has three blades 1, made in the form of one piece with the sleeve 2, mounted on the axis of the counting mechanism of the hydrometric turntable.
Лопасти винта 1 выполнены в виде желоба, изогнутого по винтовой линии.The blades of the screw 1 is made in the form of a groove, curved along a helical line.
Предмет изобретени Subject invention
Лопастной винт дл гидрометрической вертушки с горизонтальной осью, отличаюшийс тем, что, с целью повышени точности измерени продольной составл юшей скорости в турбулентных- потоках, рабочие поверхности его лопастей выполнены в виде желоба, изогнутого по винтовой линии.A blade screw for a hydrometric spinner with a horizontal axis, characterized in that, in order to improve the accuracy of measuring the longitudinal component of speed in turbulent flows, the working surfaces of its blades are made in the form of a groove bent along a helical line.
