Abstract

La présente invention concerne une pompe à eau libre comprenant un boîtier supérieur, un boîtier inférieur et un agitateur. L'agitateur (51) comprend un arbre central (511) et une aube (512). L'aube (512) est divisée en une section supérieure (5121) et une section inférieure (5122) dans une direction axiale. Une bague de guidage d'écoulement (54) est disposée sous le boîtier inférieur. Un canal d'écoulement d'eau situé entre la bague de guidage d'écoulement (54) et le boîtier inférieur va en diminuant graduellement de la périphérie vers le centre. L'invention concerne également une machine de nettoyage de type puits mettant en application la pompe à eau libre. La bague de guidage d'écoulement est disposée à une position d'entrée d'eau de la pompe à eau libre et, dans l'ordre, guide un écoulement d'eau qui pénètre une entrée d'eau et permet à l'écoulement d'eau d'entrer dans une cavité de réception inférieure (522), ce qui réduit le bruit lorsque l'aube tourne pour soutirer de l'eau. De plus, l'écoulement d'eau passe par un traitement d'accélération avant d'entrer dans la cavité de réception inférieure (522), ce qui aide à former une pression négative et à obtenir un bon effet de soutirage d'eau.
