▼產品特點/Detailed Introduction：

■力士達牌水泵葉輪、導流體采用PC（聚碳材料）及俗稱“賽鋼”的聚甲醛高分子耐磨材料，進行沖壓、成型制造而成，抗磨性強、不氧化、特別耐用，并具有不生銹、不污染的特點。

■出水節內置有復合形的“止逆調”，可以有效防止“水錘”現象及回流泥沙沉淀，使水泵啟動更加輕松自如，有效延長電機壽命，使用更持久。

■泵體采用不銹鋼外殼，機芯采用高耐磨性能的合金及復合不銹鋼材料制作，裝置有多級合金與耐磨橡膠對磨軸承結構。

■潛水電機外殼采用不銹鋼制造，整體為模塊化生產，結構縝密，絕緣性和機械噪音均達到國際同類質優產品的性能狀態，符合歐美質優標準，內部選用軸承采用質優合金推力軸承，多重密封，并設有氣動平衡反壓裝置，使運轉更平穩，效率更高，更耐用。

■獨特的浮動葉輪結構，對電機無軸向力，勝任多級高揚程使用。

■泵體外徑小，流量大，楊程高，適合小口徑深井，可顯著降低鉆井成本。

■集成化電子液位控制，實現智能自動化抽水。

■多重保護的電器控制電箱，讓電機運行更安全可靠。

■先進的靜音技術，靜音運行免去擾人之嫌。

■lishida impeller and diffuser adopt the macromolecule wear-resistance materials, and made by pressing and molding, they are high wear-resistance, with long life, and also cannot oxidize, rust or pollute.

■The multiple check valve is placed in the inner of outlet part, which can effectively prevent the impact of precipitating water and sediment of the reflux sands. ensure startup of pump fluently. also can prolong life of motor effectively.

■The body is covered with stainless case. and its rush pith is made with high-quality wear-resisting alloy and compound stainless materials, equipped with multi-level alloy and anti-wearing bearing structures with high wear-resisting rubber.

■Outer casing of pump is made from the sainless steel,the whole body is made by blocking production structure of high precision insulation and machine noise all reach the characteristics of the high-quality product of the same kinds in the world, also accord with theEuro-American high-quality standard. In the inner part uses high quality thrusting bearing, it has high seal, and also has pneumatic balance anti-press device, to ensure pump operting more stably, high eficienty and use for longer time.

■Unique floating impeller stuctures, no axi1e-centred force to the motor,capable of completing multilevel high flow.

■Small outside diameter high flow，high head， suitable for small-caliber well and can reduce the boring costs significantly.

■Integrated electric fluid-level cortrol making automatic water-pumping possible.

■Multi-stepped precise relay-cotrolled electric box enabling the motor to run safely and reliably.
