Guide d'achat de pompes lourds

La pompe à lisier est principalement utilisée pour transporter un mélange solide-liquide contenant des particules dures, largement utilisée dans le charbon, la métallurgie, l&39;exploitation minière, l&39;énergie thermique, l&39;industrie chimique, la conservation de l&39;eau et d&39;autres industries. Le mélange solide-liquide transporté dans la roue rotative à grande vitesse présente un mouvement irrégulier, les pièces de la partie humide de la pompe dans ces conditions de travail de « roue à sable liquide », soumises à une forte usure, mais aussi à la corrosion du milieu, ce qui entraîne un raccourcissement de la durée de vie de la partie humide parties. Par conséquent, la conception d&39;une pompe à lisier est fondamentalement différente de celle d&39;une pompe à eau. La conception de la pompe à eau propre vise principalement l&39;efficacité et l&39;indice de cavitation, tandis que la pompe à lisier doit se concentrer sur la cavitation, la résistance à l&39;usure, la résistance à la corrosion, etc. tout en recherchant l&39;efficacité.


De nombreux facteurs interviennent dans l&39;usure de la partie humide de la pompe à boues. pièces, et le mécanisme d&39;usure varie d&39;une pièce à l&39;autre, mais en général, il peut être divisé en trois catégories.


1, Usure par érosion


Lors du fonctionnement de la pompe à boues, les particules solides transportées dans le liquide impactent la surface des composants de la partie humide à une certaine vitesse, provoquant une perte de matière. Selon l&39;analyse de la surface d&39;usure des pièces défectueuses, le mécanisme d&39;usure par érosion peut être divisé en usure par coupe, usure par fatigue par déformation et usure composite par coupe + déformation


2. Dommages par cavitation


Lors du fonctionnement de la pompe, la zone locale de ses composants humides pour une raison quelconque, la pression absolue du liquide pompé jusqu&39;à la pression de vaporisation à la température dominante, le liquide commencera à se vaporiser à cet endroit, générant de la vapeur et formant des bulles. Ces bulles s&39;écoulent vers l&39;avant avec le liquide, à une pression élevée, la bulle rétrécit brusquement jusqu&39;à s&39;effondrer. Dans la condensation des bulles en même temps, la masse liquide remplit le vide à grande vitesse et a un fort impact sur la surface métallique. La surface métallique est fatiguée par cet impact et cet écaillage, ce qui entraîne une perte de matière et, dans les cas graves, la surface métallique est alvéolée.


3, Corrosion


Lorsque le milieu transporté présente un certain degré d&39;acidité et d&39;alcalinité, les pièces humides de la pompe à boues subiront également de la corrosion et de l&39;usure, c&39;est-à-dire une perte de matière sous l&39;action conjointe de la corrosion et de l&39;usure.


Notre société utilise de la fonte à haute teneur en chrome en alliage KmTBCr27, qui est un matériau hautement allié résistant à l&39;usure et à la corrosion, et adopte une technologie de production avancée pour améliorer la durée de vie des pièces humides de la pompe à lisier.
