Guia de compra de bombas pesadas

A bomba de polpa é usada principalmente para transportar misturas sólido-líquido contendo partículas duras, amplamente utilizada em carvão, metalurgia, mineração, energia térmica, indústria química, conservação de água e outras indústrias. A mistura sólido-líquido transportada no impulsor rotativo de alta velocidade apresenta movimento não regular, as peças da parte úmida da bomba nessas condições de trabalho de "roda de areia líquida", sujeitas a forte desgaste, mas também a suportar a corrosão do meio, resultando na redução da vida útil da parte úmida partes. Portanto, o projeto da bomba de polpa é fundamentalmente diferente do projeto da bomba de água. O projeto da bomba de água limpa busca principalmente eficiência e índice de cavitação, enquanto a bomba de polpa deve se concentrar na cavitação, resistência ao desgaste, resistência à corrosão, etc. ao mesmo tempo em que busca eficiência.


Existem muitos fatores envolvidos no desgaste da parte úmida da bomba de polpa peças, e o mecanismo de desgaste varia de peça para peça, mas em geral pode ser dividido em três categorias.


1, Desgaste por erosão


Durante a operação da bomba de polpa, as partículas sólidas transportadas no líquido impactam a superfície dos componentes da parte úmida a uma determinada velocidade, causando perda de material. De acordo com a análise da superfície de desgaste das peças com falha, o mecanismo de desgaste por erosão pode ser dividido em desgaste por corte, desgaste por fadiga por deformação e desgaste composto por corte + deformação


2, Danos por Cavitação


Na operação da bomba, a área local de seus componentes úmidos, por algum motivo, a pressão absoluta do líquido bombeado diminui até a pressão de vaporização na temperatura predominante, o líquido começará a vaporizar no local, gerando vapor e formando bolhas. Essas bolhas fluem para a frente com o líquido e, a uma alta pressão, a bolha encolhe bruscamente até entrar em colapso. Na condensação de bolhas, ao mesmo tempo, a massa líquida preenche o vazio em alta velocidade e causa um forte impacto na superfície do metal. A superfície metálica fica fatigada por esse impacto e lascamento, resultando em perda de material e, em casos graves, a superfície metálica fica com aspecto de favo de mel.


3, Corrosão


Quando o meio transportado apresenta um certo grau de acidez e alcalinidade, as peças da extremidade úmida da bomba de polpa também sofrerão corrosão e desgaste, ou seja, perda de material sob a ação conjunta de corrosão e desgaste.


Nossa empresa utiliza ferro fundido de alto cromo de liga KmTBCr27, que é um material de alta liga resistente ao desgaste e à corrosão, e adota tecnologia de produção avançada para melhorar a vida útil das peças da parte úmida da bomba de polpa.


Nós personalizamos a bomba de polpa e suas peças de acordo com os requisitos do comprador, aceitamos OEM.
