特點：Features PTL系列（并派生出PTRL型管道熱水泵、PTHL立式化工泵、PTYG型油泵）單級單吸立式管道離心泵是我公司利用優秀的水利模型，并根據各類用戶在不同使用條件下精心設計而成，符合JB/53058-93質量標準。 PTL series (derivate PTRL in-line heat exchanger pump, PTHL vertical chemical pump and PTYG oil pump) single-stage single-suction pipeline centrifugal pump is carefully designed by our company utilizing excellent water conservancy models based on different working conditions of various users, which conforms to jb/t53058-93 quality standard. PTL（PTRL）系列單級單吸立式管道離心泵由于電機與泵直聯，簡化了中間傳動的結構，增強了運轉的平穩性，軸封采用硬質合金機械密封，無泄漏。泵采用管道式結構，泵的進出口能像閥門一樣安裝在管路的任何位置及任何方向，與普通臥式泵比占地面積減少了30%，且具有運轉噪音低，振動小等特點。易損件的使用壽命大大延長。本型泵以其性能穩定、高效節能、占地面積小、結構緊湊等特點，廣受市場青睞。 The motor and pump are joined directly without transmission parts. So they operate smoothly. The shaft seal is made with hard alloy mechanical seal, therefore, there is no leakage. The inlet and outlet can be fixed anywhere like valves in pipeline. Compared with common horizontal pump, PTL series can decrease 30 percent floor space. Beside, they feature smooth operation and lower noise etc. The life of damageable parts is prolonged. In conclusion, this series pumps are favored in market because of their smooth operation, high efficiency, less energy consumption, small floor space and compact structure. 用途：Application 適用于工業、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 冷暖空調冷熱水循環 Cold and hot water circulation in air-condition 遠距離輸水 Transport water from far away 生產工藝循環增壓輸送、并適用于各種給排水設備、鍋爐等設備的配套使用 Pressurizing transport in industrial circulating system, and all kinds of water supply equipments, boiler etc. 工作條件：Operating Conditions 吸排介質的固體不溶物體積不超過體積的1%，粒度≦0.2mm The volume of non-soluble in operating medium can not exceed 1 percent than which of total medium.
