产品概述Product description

单螺杆泵是按迥转啮合容积式原理工作的新型泵种，主要工作部件是偏心螺杆(转子)和固定的衬套(定子)。定子采用无毒无味的食用橡胶制造。
由于该二部件的特殊几何形状，分别形成单独的密封容腔，介质由轴向均匀推行流动，内部流速低，容积保持不变，压力稳定，因而不会产生涡流和搅动。每级泵的输出压力为0.6MPa，扬程60m(清水)，自吸高度一般在6m以上。
因定子选用多种弹性材料制成，所以这种泵对高粘度流体的输送和含有硬质悬浮颗粒介质或含有纤维介质的输送，有一般泵种所不能胜任的特性。其流量与转速成正比。
本泵结构紧凑，体积小，维修简便。对介质的适应性强，流量平稳，压力脉动小，自吸能力高。工作温度可达120℃，如果需输送120℃-350℃高温介质，可定做。广泛用于食品、造纸、印染、化工、化肥、制药等工业部门。
Single screw pump is a late-model solution based on the working principle of return mesh volume. The main working elements are eccentric screw (rotor) and fixed lining (stator). Stator is made of nontoxic, scentless and edible rubber.
The special geometrical figures of these two parts have respectively formed up independent sealing chambers. The medium is axially flowing evenly, and slowly inside, volume remaining unchanged, and pressure kept smooth, so there will not produce any vortex and agitation. The output pressure of each stage of pump is 0.6MPa, head 60m (clean water), and self-priming height usually above 6m.
Because stator is made of several resilient materials, therefore, this pump is provided with the character to handle highly viscous fluid, medium containing hard suspended particles or fibre. This is unserviceable by other pumps. Its flow forms a direct ratio with speed.
This pump is featured by compact structure, small volume, easy maintenance, outstanding adaptability to medium, smooth flow, low pressure fluctuation and excellent self-priming capacity. The working temperature is up to 120℃. And it can be custom made to handle high temperature medium between 120℃-350℃. They are widely used in the industries of foodstuff, papermaking, printing, dyeing, chemical, fertilizer and pharmaceutical etc.
