Abstract

Inventia se refera la un lagar pentru pompe rotative verticale imersate, destinate vehicularii unor lichide încarcare cu suspensii abrazive sau neabrazive, cum ar fi: zgura si cenusa de termocentrala, nisip, oxizi metalici, diverse substante chimicecristaline, resturi menajere dejectii, fecale etc. Lagarul pentru pompe imersate, conform prezentei inventii, are etansarea la arbore postrotorica creata prin niste garnituri plate de cauciuc montate într-un corp de lagar si lubrifiate cu un lichid curat sub presiune introdus între ele prin doua conducte de alimentare si printr-un inel si o bucsa lagar prevazute cu niste dehajari inelare, cu niste gauri de comunicare si cu niste canale de alimentare, astfel încat sa observe o curgere a lichidului curat atat înspre rotorul pompei pentru evitarea patrunderii suspensiilor din lichidul pompat, cat si înspre lagarele de ghidare ale pompei pentru asigurarea ungerii acestora, iar în scopul crearii unei curgeri pe sub garnitura intermediara etansarea la arbore postrotorica si sectiunile de curgere ale lichidului curat sub presiune sunt astfel dimensiunate încat sa creeze o presiune mai mare în spatiul din garniturile dispuse la extremitatile bucsei lagar.The invention relates to a block for vertical immersed rotary pumps intended for the carriage of liquid carriers with abrasive or non-abrasive suspensions, such as: slag and ash of thermo-center, sand, metal oxides, various crystalline chemicals, household scrap, feces, etc. The immersion pump bearing according to the present invention has a post-rotor shaft seal formed by flat rubber gaskets mounted in a bearing body and lubricated with a pressurized clean fluid introduced between them through two feed pipes and through a ring and a bearing sleeve provided with some ring-shaped grooves with some communication holes and some feed channels to observe a flow of clean liquid both to the pump rotor to avoid penetration of the suspensions from the pumped liquid as well as to the pump guide bearings to assure their lubrication, and in order to create a flow under the intermediate seal, the sealing to the post-rotor shaft and the pressure-free liquid flow sections are dimensioned so as to create a greater pressure in the space in the gaskets arranged at the extremities of the bearing bush.
