螺桿泵應(yīng)在吸入截止閥完全打開的情況下啟動(dòng)，以防止過載或抽吸。螺桿泵雖然具有干燥和吸收的能力，但必須防止干旋，以免刮傷工作面。當(dāng)油溫較低或粘度很高時(shí)，泵需要啟動(dòng)時(shí)，螺桿泵應(yīng)從吸入閥和旁通閥的完全開啟開始，使泵啟動(dòng)時(shí)的負(fù)荷比較低，直到原動(dòng)機(jī)達(dá)到額定轉(zhuǎn)速為止。旁通閥逐漸關(guān)閉。當(dāng)旁通閥打開時(shí)，液體在節(jié)流狀態(tài)下在泵內(nèi)循環(huán)，循環(huán)油越多，循環(huán)時(shí)間越長，液體的熱越嚴(yán)重，甚至由于高溫變形而損壞泵。必須注意。 </p> <p> <br /> </p> <p> 2、單螺桿泵的運(yùn)行 </p> <p> 螺桿泵必須按規(guī)定的方向工作，以產(chǎn)生一定的吸力和流量。在工作時(shí)，應(yīng)檢查壓力、溫度和機(jī)械密封。對(duì)于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過20-30秒/滴，則認(rèn)為是正常的。如果螺桿泵在工作中產(chǎn)生噪聲，則經(jīng)常是由于油溫度低、油粘度高、油中空氣、耦合損失和泵的過度磨損造成的。 </p> <p> <br

3、螺桿泵的螺桿在機(jī)筒內(nèi)轉(zhuǎn)動(dòng)，物料與二者的摩擦，使螺桿與機(jī)筒的工作表面逐漸磨損：螺桿直徑逐漸縮小，機(jī)筒的內(nèi)孔直徑逐漸加大。這樣，螺桿與機(jī)筒的配合直徑間隙，隨著二者的逐漸磨損而一點(diǎn)點(diǎn)加大?？墒?，由于機(jī)筒前面機(jī)頭和分流板的阻力沒有改變，這就增加了被擠塑物料前進(jìn)時(shí)的漏流量，即物料從直徑間隙處向進(jìn)料方向流動(dòng)量增加。結(jié)果使塑膠機(jī)械生產(chǎn)量下降。這種現(xiàn)象又使物料在機(jī)筒內(nèi)停留時(shí)間增加，造成物料分解。如果是聚乙烯，分解產(chǎn)生的氯化氫氣體加強(qiáng)了對(duì)螺桿和機(jī)筒的腐蝕。 </p> <p> <br /> </p> <p> 4、物料中如有碳酸鈣和玻璃纖維等填充料，能加快螺桿和機(jī)筒的磨損。 </p> <p> <br /> </p> <p> 5、由于物料沒有塑化均勻，或是有金屬異物混入料中，使螺桿轉(zhuǎn)動(dòng)扭矩力突然增加，這種扭矩超出螺桿的強(qiáng)度極限，使螺桿扭斷。這是一種非常規(guī)***損壞。 </p> <p> <br />
