單級離心泵特點

　　單級離心泵特點
　　STL characteristics of vertical single-stage centrifugal pump

　　特點：
　　Features:

　　STL系列單級單吸立式管道離心泵為直聯(lián)式管道泵結(jié)構(gòu)，葉輪安裝于電機(jī)加長軸上，具有運(yùn)行平穩(wěn)結(jié)構(gòu)簡單、維護(hù)檢修簡便、安裝方便及占地面積�。ㄅc普通臥式泵比占地面積節(jié)省30%以上）等特點；
　　STL series of single-stage single-suction vertical pipeline centrifugal pump for direct-coupled pipeline structure, the impeller mounted on motor shaft extended, with smooth operation of simple structure, easy maintenance overhaul, easy installation, and covers an area of provincial (and ordinary horizontal Pump covers an area savings of more than 30% above) and other characteristics;

　　1、高效節(jié)能：采用CFD計算流體動力學(xué)，分析計算出泵內(nèi)壓力分布和速度分布關(guān)系、優(yōu)化泵的流道設(shè)計，確保泵有高效的水力形線，提高了泵的效率。
　　An energy-efficient: The CFD computational fluid dynamics analysis to calculate pump pressure and velocity distributions within the relationship, optimization of pump flow channel designed to ensure a highly efficient hydraulic pump-shaped lines to increase the pump efficiency.

　　2、安裝、維修方便：立式管道式結(jié)構(gòu)，泵的進(jìn)出口能象閥門一樣安裝在管路的任何位置及任何方向，安裝維修極為方便。
　　2, installation, easy maintenance: vertical pipe-type structure, import and export of pumps can be the same as the valve installed in the pipeline at any location and any direction, installation and maintenance very easy.

　　3、運(yùn)行平穩(wěn)，安全可靠：電機(jī)軸和水泵軸為同軸直聯(lián)、同心度高，運(yùn)行平穩(wěn)，安全可靠。
　　3, run smooth, safe and reliable: the motor shaft and pump shaft for coaxial Direct, high concentricity, run smooth, safe and reliable.

　　4、不銹鋼軸套：軸的機(jī)封位置是相對易被銹蝕之處，直聯(lián)式泵軸一旦被銹蝕，易造成機(jī)械密封失效。ＳＴＧ泵此處采用鑲配不銹鋼軸套，避免銹蝕發(fā)生，提高了軸壽命，降低了運(yùn)行維護(hù)成本。
　　4, stainless steel sleeve: the machine shaft seal is relatively susceptible to corrosion of the position of Office, the direct-coupled pump shaft once rust, could easily lead to mechanical seal failure. STG pump with stainless steel sleeve inserts used here to avoid the corrosion occurrence of increased life expectancy axis, reducing operation and maintenance costs.

　　5、軸承：泵所配電機(jī)中，Y（Y2）280以下軸伸端軸承（包括Y180以下風(fēng)葉端軸承）采用封閉式軸承，正常使用時，免電機(jī)軸承的維護(hù)保養(yǎng)。
　　5, bearing: pumps are fitted with motors, Y (Y2) 280 The following shaft extension ends (including Y180 following fan-side bearing) using closed-end bearing, normal use, maintenance-free motor bearings.

　　6、機(jī)封：機(jī)械密封基件一般選用橡膠波紋管結(jié)構(gòu)，將傳統(tǒng)機(jī)械密封中軸上密封由O形圈的線密封改為橡膠件的兩道面密封，在清水介質(zhì)時提高了密封效果。
　　6 Seal: Mechanical seal the base parts generally used in rubber bellows structure, the traditional mechanical seal in the shaft seal from the O-ring seal into the line of the two side rubber seal, in water medium improved sealing effect.
