　　螺杆泵的转速选用

　　choose the speed of screw pump螺杆泵的流量与转速成线性关系，相对于低转速的螺杆泵，高转速的螺杆泵虽然能增加了流量和扬程，但功率明显增大，高转速加速了转子与定子间的磨耗，必定使螺杆泵过早失效，而且高转速螺杆泵的定转子长度很短，极易磨损，因而缩短了螺杆泵的使用寿命。通过减速机或无级调速机构来降低转速，使勘转速保持在每分三百转以下较为合理的范围内，与高速运转的螺杆泵相比，使用寿命能延长几倍。

　　Screw pump flow and speed into a linear relationship, relative to the low speed of the screw pump, screw pump high speed can increase the flow and head, but significantly increased power, high-speed accelerated between the rotor and the stator wear, premature failure will make screw pump, and high speed screw pump rotor length is very short, easy to wear, and thus shorten the life of the screw pump. To reduce the speed stepless speed reducer or by institutions, the survey speed to maintain in the range of three hundred RPM are reasonable,compared with the high speed screw pump, can extend the service life several times.六、螺杆泵的品质

　　the quality of the screw pump现在市场上的螺杆泵的种类较多，相对而言，进口的螺杆泵设计合理，材质精良，但价格较高，服务方面有的不到位，配件价格高，订货周期长，可能影响生产的正常运行。国内生产的大都仿制进口产品，产品质量良莠不齐，在选用国内生产的产品时，在考虑其性价比的时候，选用低转速，长导程，传动量部件材质优良，额定寿命长的产品。

　　Now many type of screw pump on the market, relatively speaking, the screw pump designed imported, material well, but the price is high, the service and some are not in place, fitting high price, order cycle length, may affect the normal operation of production. Most of the domestic production of generic imported products, product quality uneven, some good and some bad, in the selection of domestically produced product, when considering its cost, use low speed, long lead, high transmission capacity component material, rated long life products.七、确保杂物不进入泵体

　　to ensure that debris does not enter the pump body湿污泥中混入的固体杂物会对螺杆泵的橡胶材质定子造成损坏，所以确保杂物不进入泵的腔体是很重要的，很多污水厂在泵前加装了粉碎机，也有的安装格栅装置或滤网，阻挡杂物进入螺杆泵，对于格栅应及时清捞以免造成堵塞。

　　Wet sludge mixed with the solid debris would rubber material damage to the stator of the screw pump, so to ensure that debris does not enter the pump chamber is very important,many wastewater treatment plant before the installation of a grinder pump, and some install grid device or filter, blocking debris into the pump, the grid should be cleared in time to avoid clogging fishing.八、避免断料

　　avoid cutting螺杆泵决不允许在断料的情形下运转，一经发生，橡胶定子由于干磨擦，瞬间产生高温而烧坏，所以，粉碎机完好，格栅畅通是螺杆泵正常运转的必要条件之一，为此，有些螺杆泵还在泵身上安装了断料停机装置，当发生断料时，由于螺杆泵其有自吸功能的特性，腔体内会产生真空，真空装置会使螺杆泵停止运转。

　　Screw pump must not be allowed to operate in the cutting conditions, the occurrence, the rubber stator due to dry friction, instant high heat and burn out, so, grinder intact, grille unimpeded is one of the necessary conditions for the normal operation of the screw pump,therefore, some screw pump in pump body installed end feeding stop device, when cutting,due to its characteristics of screw pump self-priming function, will produce a vacuum chamber, a vacuum device causes the screw pump to stop running.九、保持恒定的出口压力

　　maintain a constant outlet pressure螺杆泵是一种容积式回转泵，当出口端受阻以后，压力会逐渐升高，以至于超过预定的压力值。此时电机负荷急剧增加。传动机械相关零件的负载也会超出设计值，严重时会发生电机烧毁、传动零件断裂。为了避免螺杆泵损坏，一般会在螺杆泵出口处安装旁通溢流阀，用以稳定出口压力，保持泵的正常运转六九个小时后 HSND系列三螺杆泵型号 HSND系列三螺杆泵HSND系列三螺杆泵详细说明HSND系列三螺杆泵是本公司顺应市场需求而专门设计开发的一种效率高、噪音低、用途广、寿命长的产品，它特别适合黏度在380cst ~ 460cst以上无固体颗粒、无腐蚀性介质的输送。产品按照GB/T10886-2002设计生产。

　　Screw pump is a positive displacement rotary pumps, when the exit blocked, the pressure will gradually increase, so that the pressure exceeds a predetermined value. At this point a sharp increase in the motor load. Transmission machinery related parts of the load will exceed the design value, the motor burned, transmission parts breakage occurred seriously. Screw in order to avoid damage, usually installed in the screw pump bypass relief valve outlet, the outlet pressure to stabilize, maintain the normal operation of the pump after six nine hours of HSND series three screw pump models of HSND series three screw pump of HSND series three screw pump is a detailed description of HSND series three screw pump is a kind ofefficiency of the company to comply with the market demand and the professional design and development of high, low noise, wide application, long service life of product, it is particularly suitable for conveying viscosity in 380cst ~ 460cst above without solid particles, non corrosive medium. Products in accordance with the GB/T10886-2002 design and production.
