增氧排灌两用浮水泵的结构主要由电动机、泵体、浮体三大部分组成。电动机在整机的上部,外由防水罩和固定板组成气室,籍气室浮力浮于水面,装有机械密封件的电动机轴通过固定板伸出气室,下达泵壳,与电机同轴的叶轮抽送水流进入管道。浮水泵变吸水扬程为压水扬程,进水口在水面下25～50厘米处,既不会吸入河底泥沙,也不会吸入河面浮萍等,缩短了管道,又无需装底阀,故可节电10～30％。浮水泵用于农田排灌,不仅具有潜水泵的功能,而且能随水位升降,不受水底泥沙
Aerobic irrigation and drainage dual-purpose floating pump structure mainly by the motor, pump body, floating body composed of three parts. Motor in the upper part of the machine, the outer cover by the waterproof cover and fixed gas chamber, the buoyancy of the gas chamber floating on the water, equipped with mechanical seal motor shaft through the fixed plate extends out of the gas chamber, the pump shell, with the motor coaxial Impeller pumps water into the pipe. Floating pump variable suction head lift pressure water, water inlet 25 to 50 cm below the surface of the water will neither inhale the river sediment, it will not inhale the river duckweed, etc., shorten the pipeline, but also do not need to install the valve, so Can save 10 ~ 30%. Floating pump for farmland irrigation and drainage, not only has the function of submersible pumps, but also with the water level rise and fall, from the sediment
