特點(diǎn): Features PTW型帕特臥式離心泵是在IS型單級(jí)離心式清水泵以及ISG型管道式離心泵的基礎(chǔ)上進(jìn)行設(shè)計(jì)制造而成； Designed on the basic of IS single stage centrifugal. 本系列泵在原IS泵的基礎(chǔ)上對(duì)其結(jié)構(gòu)進(jìn)行了大膽的改進(jìn)設(shè)計(jì),同時(shí)吸取了ISG型泵的優(yōu)點(diǎn),性能參數(shù)采用了ISO2858標(biāo)準(zhǔn),產(chǎn)品質(zhì)量執(zhí)行JB/T53062-93標(biāo)準(zhǔn),其經(jīng)濟(jì)技術(shù)性能指標(biāo)達(dá)到國(guó)內(nèi)同類產(chǎn)品先進(jìn)水平； Take advantage of virtues of ISG pump, performance date according to ISO2858 standard and product quality performs JB/T53062-93 standard so the technical performance is advanced in domestic congener products. PTW型泵由于電機(jī)與泵直聯(lián),簡(jiǎn)化了中間傳動(dòng)的結(jié)構(gòu),增強(qiáng)了運(yùn)行的平穩(wěn)性,并比普通臥式泵占地面積減少了30%,軸封采用硬質(zhì)合金機(jī)械密封,壽命長(zhǎng),且具有噪音低,維修方便,震動(dòng)小等優(yōu)點(diǎn)。 The motor and pump are joined directly without transmission parts. So they operate smoothly. Compared with common horizontal pump. PTW series can decrease 30 percent floor space. The shaft seal is made with hard alloy mechanical seal whose working life is long-Besides, the pump features low noise, convenient maintenance and light shake. 用途 Applications 適用于工業(yè)、城市給水、高層建筑供水 Water supply in industry, cities and high-rises 消防管道增壓 Fire fighting pipeline pressurizing 冷暖空調(diào)冷熱水循環(huán) Cold and hot water circulation in air-condition 遠(yuǎn)距離輸水 Transport water from far away 生產(chǎn)工藝循環(huán)增壓輸送、并適用于各種給排水設(shè)備、鍋爐等設(shè)備的配套使用 Pressurizing transport in industrial circulating system, and all kinds of water supply equipments, boiler etc. 工作條件：Operating Conditions 流量范圍 Capacity range:2～1800m3/h; 揚(yáng)程范圍 Head range: 5～150m; 泵系統(tǒng)最高工作壓力≦1.6MPa，即吸入口壓力+泵揚(yáng)程≦1.6MPa System Max: working pressure should not be greater than 1.6MPa, namely pressure in suction add to head of head should not be greater than 1.6MPa. 介質(zhì)溫度 Liquid temperature:-15℃﹤T﹤+105℃ 周圍環(huán)境溫度 Ambient temperature: ≦40℃ 電機(jī)防護(hù)等級(jí) Motor＇s degree of protection:IP54或IP44； 電機(jī)絕緣等級(jí) Motor＇s class of insulation: B級(jí)或F級(jí)
