Guida all'acquisto di pompe pesanti

La pompa per fanghi è utilizzata principalmente per trasportare miscele solido-liquide contenenti particelle dure ed è ampiamente utilizzata nell&39;industria carbonifera, metallurgica, mineraria, termoelettrica, chimica, di conservazione delle acque e in altri settori. La miscela solido-liquido trasportata nella girante rotante ad alta velocità presenta un movimento non regolare, le parti immerse della pompa in queste condizioni di lavoro "ruota di sabbia liquida" sono soggette a forte usura, ma anche a sopportare la corrosione del mezzo, con conseguente riduzione della durata delle parti immerse. parti. Pertanto, la progettazione della pompa per fanghi è fondamentalmente diversa da quella della pompa per acqua. La progettazione della pompa per acqua pulita persegue principalmente l&39;efficienza e l&39;indice di cavitazione, mentre la pompa per fanghi dovrebbe concentrarsi sulla cavitazione, sulla resistenza all&39;usura, sulla resistenza alla corrosione, ecc. perseguendo al contempo l&39;efficienza.


Sono molti i fattori coinvolti nell&39;usura della parte umida della pompa per fanghi parti e il meccanismo di usura varia da parte a parte, ma in generale può essere suddiviso in tre categorie.


1, Usura da erosione


Durante il funzionamento della pompa per fanghi, le particelle solide trasportate dal liquido colpiscono la superficie dei componenti della parte umida a una certa velocità, causando la perdita di materiale. Secondo l&39;analisi della superficie di usura delle parti guaste, il meccanismo di usura da erosione può essere suddiviso in usura da taglio, usura da fatica da deformazione e usura composita da taglio + deformazione


2. Danni da cavitazione


Durante il funzionamento della pompa, per qualche motivo, l&39;area locale dei suoi componenti umidi, la pressione assoluta del liquido pompato fino alla pressione di vaporizzazione alla temperatura prevalente, il liquido inizierà a vaporizzare in quel punto, generando vapore e formando bolle. Queste bolle fluiscono in avanti insieme al liquido, fino a raggiungere un&39;elevata pressione; la bolla si restringe bruscamente fino a collassare. Nella condensazione delle bolle, allo stesso tempo, la massa liquida riempie il vuoto ad alta velocità e ha un forte impatto sulla superficie metallica. La superficie metallica viene affaticata da questo impatto e si scheggia, con conseguente perdita di materiale e, nei casi più gravi, la superficie metallica assume una forma a nido d&39;ape.


3. Corrosione


Quando il mezzo trasportato ha un certo grado di acidità e alcalinità, anche le parti bagnate della pompa per fanghi subiranno corrosione e usura, ovvero la perdita di materiale sotto l&39;azione congiunta di corrosione e usura


La nostra azienda utilizza ghisa ad alto tenore di cromo in lega KmTBCr27, che è un materiale ad alta lega resistente all&39;usura e alla corrosione, e adotta una tecnologia di produzione avanzata per migliorare la durata delle parti bagnate della pompa per fanghi


Abbiamo personalizzato pompe per fanghi e componenti di pompe in base alle esigenze dell&39;acquirente, accettati OEM.
