Description
(54) ЛОПАТКА РОТОРНОЙ МАШИНЫ(54) RAILWAY BLADDER
1,one,
Изобретение относитс к насосо- и компрессоростроению , касаетс усовершенствовани роторных машин пластинчатого типа и может использоватьс в насосах, вакуумных насосах, компрессорах.The invention relates to pump and compressor engineering, relates to the improvement of rotary machines of the plate type and can be used in pumps, vacuum pumps, compressors.
Известна лопатка роторной машины, содержаща установленную в пазу ротора и контактирующую со статором пластину, выполненную из армированного полимерного материала 1.The known blade of the rotor machine contains a plate installed in the groove of the rotor and in contact with the stator, made of reinforced polymeric material 1.
Недостатком указанной лопатки вл етс то, что она имеет невысокую надежность и долговечность вследствие трени и износа контактирующих поверхностей, в результате чего происходит расслоение материала, из которого она выполнена.The disadvantage of this blade is that it has a low reliability and durability due to friction and wear of the contacting surfaces, as a result of which the material from which it is made is delaminated.
Наиболее близким техническим решением из известных к предлагаемой вл етс лопатка роторной машины, содержаща установленную в пазу ротора и контактирующую со статором пластину, выполненную из армированного полимерного материала и снабженную со стороны паза V-образным кожухом (2.The closest technical solution known to the present invention is a blade of a rotary machine, containing a plate installed in the slot of the rotor and in contact with the stator, made of a reinforced polymer material and provided on the side of the slot with a V-shaped casing (2.
Недостатком этой лопатки также вл етс невысока надежность вследствие трени The disadvantage of this blade is also low reliability due to friction.
22
участков, незащищенных кожухом - со стороны статора и с торцов.areas unprotected by the casing - from the side of the stator and from the ends.
Цель изобретени - повышение надежности и улучшение условий трени .The purpose of the invention is to increase reliability and improve friction conditions.
Указанна цель достигаетс тем, что пластина со стороны статора снабжена дополнительным кожухом, а с торцов - покрытием в виде фольги.This goal is achieved by the fact that the plate on the side of the stator is provided with an additional casing, and from the ends is coated in the form of a foil.
На фиг. 1 изображена описываема лопатка , установленна в роторной машине, поперечный разрез; на фиг. 2 - лопатка, FIG. 1 shows the described blade installed in a rotary machine, a cross section; in fig. 2 - scapula,
10 поперечное сечение; на фиг. 3 - покрытие в виде фольги, развертка; на фиг. 4 - V-образный кожух.10 cross section; in fig. 3 - a covering in the form of a foil, development; in fig. 4 - V-shaped casing.
