SN系列螺杆泵的选泵关键
选泵关键
率先应依据油品的粘度抉择贴切的泵转速,以保证泵的(NPSH)r能中意用户的切实吸入条件。
介质粘度V>760mm2/s时,请与我厂联系,我厂帮助用户先泵。
从功能表入选定泵的格式及相应粘度下的压力流量后,能够查到泵的轴功率N,选定配套电机功率Nm时应功率备量。
Nm≥K×N其值参见下表:
| N(Kw) | N≤5 | 5<N≤10 | 10<N≤50 | N>50 |
| K | 1.25 | 1.2 | 1.15 | 1.1 |
材料的抉择
①输送柴油、重油(燃料油),泵套用锡青铜。
②输送细腻油、液压油,泵套用灰铸铁、球铁、锡青铜。
③输送植物油,或含酸和碱等侵蚀性液体,泵体、螺杆、泵套等零件批准不锈钢或其它耐侵蚀材料。

一、SNH三螺杆泵概述:
三螺杆泵是无脉动轴向输送具有定然细腻性介质的定量容积式低压转子泵,适于输送燃料油、细腻油、液压油、矿物油等油类和具有细腻性的流动性液体。所输送的介质中不得含有任何磨料颗粒和对泵材料有侵蚀的物质。SNH系列三螺杆泵由特异型线(摆线)构成的螺旋型面,当电机或马达驱动积极螺杆转动时,其不时行动的各个密封腔室逐渐构成真空,液体在大气压的作用下由吸入口吸入并沿轴向继续、无脉动的输送到排泄口,无搅拌、乳化假象。
A, SNH three screw pump:
Three screw pump is quantitative volumetric low-pressure rotor pump without pulsation of axialtransport a certain lubricating medium, suitable for delivery of fuel oil, lubricating oil, hydraulic oil, mineral oil and other oil and fluid with lubricity. The transmission medium not containingany material abrasive particles and the corrosion of pump material. The SNH series threescrew pump by special type line (cycloidal) spiral surface composed of, when the motor ormotor driven active screw rotation, the constant movement of the sealing cavity formed invacuum, the liquid under the action of atmospheric pressure by the suction port of the suctionalong the axial direction and no pulsation continuous, transported to the outlet, no mixing,emulsifying phenomenon.
