●主權(quán)利要求：
浸沒式三螺桿泵，其組成包括泵體、襯套、主動(dòng)螺桿、從動(dòng)螺桿，泵體具有位于其下部
的低壓腔和位于其上部的高壓腔，低壓腔的下端具有吸油口，高壓腔的一側(cè)具有出油口，
其特征是低壓腔中具有一個(gè)與主動(dòng)螺桿下端對應(yīng)的儲油槽，該儲油槽的一側(cè)槽壁為低壓腔的內(nèi)壁，
另一側(cè)槽壁的上端低于低壓腔的上端而高于襯套的下端，該儲油槽的底部位于主動(dòng)螺桿的下端與吸油口之間。
注：同一規(guī)格而螺旋升角不同的螺桿泵型號，其外形安裝尺寸一般是一樣的，而流量是不同的。
在相同工況條件下，如：介質(zhì)、溫度、黏度、螺桿的材質(zhì)加工工藝精度等相同，螺旋升角小的型號，
形成壓力的能力更好，但是流量就比螺旋升角大的型號小。反之，螺旋升角大的，泵的流量就比螺旋
升角小的泵就要大，但是泵形成壓力的能力就相對較弱。

●性能特點(diǎn)
1.自吸能力強(qiáng)，可輸送具有潤滑性且不含固體顆粒的液體介質(zhì)。
2.結(jié)構(gòu)緊湊，不需用同步齒輪傳動(dòng)，機(jī)械效率高；
3.噪聲振動(dòng)小，性能穩(wěn)定，使用壽命長，維護(hù)方便；
4.特別設(shè)有儲油裝置，可在二次啟動(dòng)時(shí)免去加油的麻煩；
5.具有多種聯(lián)結(jié)結(jié)構(gòu)形式，便于設(shè)計(jì)選型；
6.泵出口通徑DN50mm（含50mm）以下，其進(jìn)出油口聯(lián)接形式采用圓柱管螺紋，DN50mm以上則采用法蘭聯(lián)接。

●HSJ浸沒式三螺桿泵的工作原理：
該三螺桿泵是由一根主動(dòng)螺桿和二根從動(dòng)螺桿相互嚙合固定于襯套內(nèi)，螺桿型面由雙頭擺線和圓弧齒形組成。
螺桿副和襯套安裝在泵體內(nèi)，當(dāng)主動(dòng)螺桿在原動(dòng)機(jī)帶動(dòng)下旋轉(zhuǎn)，由主、從動(dòng)螺桿在一定嚙合螺旋面長度下形成密封腔，
從動(dòng)螺桿因螺旋面兩邊的壓力差，被輸送液體介質(zhì)推動(dòng)而旋轉(zhuǎn)，此時(shí)輸送液體進(jìn)入泵吸入口后沿軸向均勻連續(xù)地進(jìn)入密封腔內(nèi)，
并平穩(wěn)、無攪動(dòng)地從泵吸入腔到達(dá)排出腔，從而達(dá)到輸送液體介質(zhì)的功能。

注：同一規(guī)格而螺旋升角不同的螺桿泵型號，其外形安裝尺寸一般是一樣的，而流量是不同的。在相同工況條件下，
如：介質(zhì)、溫度、黏度、螺桿的材質(zhì)加工工藝精度等相同，螺旋升角小的型號，形成壓力的能力更好，
但是流量就比螺旋升角大的型號小。反之，螺旋升角大的，泵的流量就比螺旋升角小的泵就要大，
但是泵形成壓力的能力就相對較弱。如下表相應(yīng)對比顯示：（相對的工況條件相同的情況下比較）
螺旋升角大小形成壓力的能力形成流量的能力驅(qū)動(dòng)所需軸功率
大         形成壓力相對弱相對流量大些軸功率大
小         形成壓力相對強(qiáng) 相對流量小些軸功率小
