②流道寬，可以輸送含有固體物的水。 </p> <p> ③泵體結(jié)構(gòu)是半開的，可以觀察到泵內(nèi)的運(yùn)行情況。 </p> <p> ④吸入側(cè)流態(tài)對水力性能影響甚微，對吸水池?zé)o特殊要求，基礎(chǔ)開挖深度小，水工建筑物施工簡單，土建費(fèi)用少。 </p> <p> 其缺點(diǎn)是： </p> <p> ①尺寸大，占地面積也大。 </p> <p> ②受機(jī)械加工條件限制，泵軸不能太長，因而揚(yáng)程較低，一般不超過10m。 </p> <p> ③吸水面、出水面高度變化不能太大，否則會影響工作效率，增加能耗。 </p> <p> <br /> </p><p> 在螺桿泵的水力特征檢測中，輕易涌現(xiàn)容積效力大于100％的狀況，同時(shí)螺桿泵實(shí)踐排量的盤算方式存在爭議，為處理這個(gè)問題筆者在對螺桿泵水力特征實(shí)驗(yàn)數(shù)據(jù)和檢測體系鉆研基本上，展開了螺桿泵容積效力的鉆研，對螺桿泵容積效力的檢測提出了幾點(diǎn)熟悉。 </p> <p> 螺桿泵是一種旋轉(zhuǎn)容積泵，其容積效力隨壓力的降低而降落，額外壓力下的容積效力大小是判斷泵及格與否的重要根據(jù)。在螺桿泵的水力特征實(shí)驗(yàn)中，會涌現(xiàn)容積效力大于100％的狀況，一種是在零壓力點(diǎn)和非零壓力點(diǎn)下都涌現(xiàn)容積效力大于100％，同時(shí)在零壓力點(diǎn)容積效力為100％時(shí)在非零壓力點(diǎn)也會涌現(xiàn)容積效力大于100％的狀況。針對這個(gè)問題筆者對螺桿泵容積效力展開了實(shí)驗(yàn)鉆研，并對實(shí)驗(yàn)數(shù)據(jù)進(jìn)行了剖析。
