Abstract

uma bomba submersível que tem menos desgaste nas superfícies de contato de um corpo da válvula e uma guia de corpo da válvula, em que uma guia de corpo da válvula 122 para guiar um corpo da válvula 120 de uma válvula de retenção 122 utilizado na bomba submersível, em uma direção axial da bomba submersível, inclui: uma pluralidade de partes de guia 122a que entram em contato com o corpo da válvula 120 e guiam o corpo da válvula 120 na direção axial da bomba submersível. a guia de corpo da válvula 122 inclui ainda uma pluralidade de partes de anexação 122b para fixar a guia de corpo da válvula 122 para a bomba submersível e, em uma porção de contato 122d da parte de guia 122a com o corpo da válvula 120, uma seção transversal da parte de guia 122a perpendicular à direção axial da bomba submersível projeta-se em uma direção em direção ao corpo da válvula 120, e é curvada, as partes de guia 122a e as partes de anexação 122b sendo integradas como uma peça única.a submersible pump having less wear on the contact surfaces of a valve body and a valve body guide, wherein a valve body guide 122 for guiding a valve body 120 of a check valve 122 used in the submersible pump in an axial direction of the submersible pump includes: a plurality of guide portions 122a which contact the valve body 120 and guide the valve body 120 in the axial direction of the submersible pump. valve body guide 122 further includes a plurality of attachment parts 122b for securing valve body guide 122 to the submersible pump and, in a contact portion 122d of guide part 122a with valve body 120, a The cross-section of the guide portion 122a perpendicular to the axial direction of the submersible pump projects in one direction toward the valve body 120, and is bent, the guide portions 122a and the attachment portions 122b being integrated as a single part.
