▼產品特點/Detailed Introduction：

■力(li)士達牌水泵葉輪、導流體(ti)采用(yong)PC（聚碳(tan)材料）及俗稱(cheng)“賽(sai)鋼”的(de)聚甲醛高分子耐磨(mo)(mo)材料，進行沖壓、成型制造(zao)而成，抗(kang)磨(mo)(mo)性(xing)強(qiang)、不(bu)(bu)氧化(hua)、特別耐用(yong)，并具有不(bu)(bu)生銹、不(bu)(bu)污染(ran)的(de)特點(dian)。

■出水(shui)(shui)(shui)節內置有復合形(xing)的“止逆調”，可以(yi)有效(xiao)防(fang)止“水(shui)(shui)(shui)錘”現象及回流(liu)泥沙沉淀(dian)，使(shi)水(shui)(shui)(shui)泵啟動更(geng)加輕松自如，有效(xiao)延長電機壽(shou)命，使(shi)用更(geng)持久。

■泵體采用(yong)不銹鋼外殼，機(ji)芯采用(yong)高耐磨(mo)性能的合(he)金及復合(he)不銹鋼材料制作，裝置有多級合(he)金與(yu)耐磨(mo)橡膠對(dui)磨(mo)軸(zhou)承結構。

■潛水電機外(wai)殼采(cai)用不(bu)銹(xiu)鋼制造，整體為模塊化生產(chan)，結構縝密，絕緣性和(he)機械噪音均達到國際同類質優(you)產(chan)品的性能狀態，符合歐(ou)美質優(you)標準，內部選用軸承采(cai)用質優(you)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(geng)平穩，效率(lv)更(geng)高，更(geng)耐(nai)用。

■獨特的浮動葉輪結(jie)構，對電機(ji)無軸(zhou)向力，勝(sheng)任多級高揚程(cheng)使用。

■泵體(ti)外徑(jing)小(xiao)，流量大，楊程(cheng)高，適合(he)小(xiao)口徑(jing)深井，可顯著降(jiang)低鉆井成本。

■集成化(hua)電(dian)子液位控制，實現智能自動化(hua)抽水。

■多重保護的電器控制(zhi)電箱，讓電機運行更(geng)安全可靠。

■先進的靜(jing)音技術，靜(jing)音運行(xing)免去擾人之嫌(xian)。

■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.
