產品概述Product description

單螺桿泵是按迥轉嚙合容積式原理工作的新型泵種，主要工作部件是偏心螺桿(轉子)和固定的襯套(定子)。定子采用無毒無味的食用橡膠制造。
由于該二部件的特殊幾何形狀，分別形成單獨的密封容腔，介質由軸向均勻推行流動，內部流速低，容積保持不變，壓力穩定，因而不會產生渦流和攪動。每級泵的輸出壓力為0.6MPa，揚程60m(清水)，自吸高度一般在6m以上。
因定子選用多種彈性材料制成，所以這種泵對高粘度流體的輸送和含有硬質懸浮顆粒介質或含有纖維介質的輸送，有一般泵種所不能勝任的特性。其流量與轉速成正比。
本泵結構緊湊，體積小，維修簡便。對介質的適應性強，流量平穩，壓力脈動小，自吸能力高。工作溫度可達120℃，如果需輸送120℃-350℃高溫介質，可定做。廣泛用于食品、造紙、印染、化工、化肥、制藥等工業部門。
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.
