▼产品特点/Detailed Introduction：

■力士达牌水泵叶轮、导流体采用PC（聚碳材料）及俗称“赛钢”的聚甲醛高分子耐磨材料，进行冲压、成型制造而成，抗磨性强、不氧化、特别耐用，并具有不生锈、不污染的特点。

■出水节内置有复合形的“止逆调”，可以有效防止“水锤”现象及回流泥沙沉淀，使水泵启动更加轻松自如，有效延长电机寿命，使用更持久。

■泵体采用不锈钢外壳，机芯采用高耐磨性能的合金及复合不锈钢材料制作，装置有多级合金与耐磨橡胶对磨轴承结构。

■潜水电机外壳采用不锈钢制造，整体为模块化生产，结构缜密，绝缘性和机械噪音均达到国际同类质优产品的性能状态，符合欧美质优标准，内部选用轴承采用质优合金推力轴承，多重密封，并设有气动平衡反压装置，使运转更平稳，效率更高，更耐用。

■独特的浮动叶轮结构，对电机无轴向力，胜任多级高扬程使用。

■泵体外径小，流量大，杨程高，适合小口径深井，可显著降低钻井成本。

■集成化电子液位控制，实现智能自动化抽水。

■多重保护的电器控制电箱，让电机运行更安全可靠。

■先进的静音技术，静音运行免去扰人之嫌。

■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.
