Abstract

FIELD: axial multistage compressors. SUBSTANCE: compressor consists of three tiers and three rotors of different diameters which are provided with blades. Each compressor of lesser diameter is mounted in spaced relation in rotor of compressor of larger diameter; smallest rotor is rigidly secured on shaft. Rotors of larger diameters are received by grooves of the same diameter which ar made in end shields of housing on either end; diameter of housing provides for receiving maximum compressor at minor clearance. Blades of all axial compressors mounted in single housing are provided with three-stage hubs; each stage is inclined to longitudinal axis at definite angle. Cylindrical surface of rotor if each compressor is divided into several sectors; length of inlet part of each blade is gradually increased within each sector forming air intake chamber. Thickness of each blade increases at its center portion towards its trailing edge whose thickness is constant; its lateral planes form slotted passages together with lateral planes of adjacent blades. Holes used for delivery of fuel are provided in body of rotor fitted on shaft; these holes pass through body of blades and extend to inter-blade space where jets are mounted; jets are connected with fuel passages passing through body of shaft. EFFECT: improved pressure characteristics and extended range of operational capabilities.

Изобретение относится к соевым многоступенчатым компрессорам. Цель изобретения - повышение напорных характеристик и расширение эксплуатационных возможностей. Компрессор выполнен как бы трехъярусным и состоит из трех роторов разного диаметра с лопастями. Каждый компрессор меньшего диаметра устанавливается с зазором в ротор компрессора большего диаметра, а самый меньший ротор жестко закреплен на валу. Роторы больших диаметров установлены в пазы, выполненные по их диаметру с обоих концов в торцевых крышках корпуса, диаметр которого таков, что вмещает наибольший компрессор с небольшим зазором. Лопасти всех осевых компрессоров, установленных в едином корпусе, ступицы которого жестко закреплены на валу, выполнены трехступенчатыми, и каждая ступень имеет свой угол наклона к продольной оси, причем цилиндрическая поверхность ротора каждого компрессора разделена на несколько одинаковых секторов, в пределах каждого из которых происходит постепенное увеличение длины входной части каждой лопасти, что способствует образованию воздухозаборной полости, а у средней части каждой лопасти постепенно увеличивается толщина в сторону выходной части лопасти, толщина которой остается постоянной, и ее боковые плоскости образуют с боковыми плоскостями соседних лопастей щелевые каналы, при этом для подачи топлива в теле ротора, сидящего на валу, выполнены отверстия, проходящие через тело лопастей и выходящие в межлопастное пространство, в которые устанавливаются жиклеры, соединенные с топливными каналами, проходящими через тело вала.The invention relates to soybean multistage compressors. The purpose of the invention is to increase pressure characteristics and expand operational capabilities. The compressor is made as it were three-tiered and consists of three rotors of different diameters with blades. Each compressor of a smaller diameter is installed with a gap in the rotor of a compressor of a larger diameter, and the smallest rotor is rigidly fixed to the shaft. The rotors of large diameters are installed in grooves made according to their diameter from both ends in the end caps of the housing, the diameter of which is such that it accommodates the largest compressor with a small gap. The blades of all axial compressors installed in a single housing, the hubs of which are rigidly fixed to the shaft, are made in three stages, and each stage has its own angle of inclination to the longitudinal axis, and the cylindrical surface of the rotor of each compressor is divided into several identical sectors, within each of which there is a gradual an increase in the length of the inlet part of each blade, which contributes to the formation of an air intake cavity, and in the middle part of each blade the thickness gradually increases towards the exit part of the blade, the thickness of which remains constant, and its lateral planes form slotted channels with the lateral planes of adjacent blades, while for supplying fuel in the body of the rotor sitting on the shaft, holes are made that pass through the body of the blades and exit into the inter-blade space, into which nozzles are connected to the fuel channels passing through the shaft body.
