一用户将QY—15型潜水泵用于基建时排水,使用不久电机烧坏。现场分析,因水位过低,用户将泵横躺着使用且已陷入泥中,电机散热不良,导致电机烧坏。因此,潜水泵一定要垂直吊在水中使用,且不允许陷进泥里。另一用户将QY—7型潜水泵,用于铺设地下电缆时施工排水,运行3、4小时后就不出水了。经查,水泵叶轮严重磨损变形,原因是:边施工,边抽
A user will QY-15-type submersible pumps for infrastructure drainage, the use of motor burn soon. On-site analysis, due to water level is too low, the user will be lying on the pump and has been stuck in the mud, poor motor cooling, resulting in motor burn out. Therefore, the submersible pump must be suspended vertically in the water to use, and not allowed to fall into the mud. Another user will QY-7-type submersible pumps, drainage cables used in the construction of underground construction drainage, after running 3,4 hours without water. The investigation, the pump impeller wear serious deformation, because: while construction, while pumping
