TA(Kg.m)=973.5×KW/N(rpm)=716.2×HP/N(rpm)或 TA(N·m)=9550×KW/N(r/min) 3.由被正系數表中查得負載條件系數 K1 ，運轉時間系數 K2 ，起動停止頻度系數 K3 ，周圍環(huán)境溫度系數K4 ，求得補正扭力 [TD] 。 TD=TA · K1 · K2 · K3 · K4 4，山東電纜卷筒流體哪個牌子好.選用聯軸器的常用轉矩必須大于被正轉矩。 5.聯軸器所能承受的較大扭力必須大于原動側及被動側雙方所產生的較大扭力，山東電纜卷筒流體哪個牌子好。 6.確定孔徑范圍是否適用。 7.除了以上的選定步驟外，山東電纜卷筒流體哪個牌子好，對于振動頻率亦須檢討。即轉矩變動的頻率與軸的固有振動數避免造成共振的現象產生。流體受壓力作用時體積縮小、密度增大的性質稱為流體的壓縮性。山東電纜卷筒流體哪個牌子好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

如果總的有效斷面或平均流速沿流程不變，各有效斷面上相應點的流速業(yè)不變，且流線為平行直線，這樣的穩(wěn)定流動稱為均勻流。均勻流中沒有加速度，因而不存在慣性力。當有效斷面沿流程變化，或者有效斷面不變，但各斷面上速度分布改變時這種流動稱為非均勻流。例如，有效斷面收縮或擴大處、圓管轉彎處、流線為夾角不同的曲線或直線等都屬于非均勻流。非均勻流中有加速度，因而存在慣性力。如果有效斷面沿流程變化劇烈或斷面流速分布變化劇烈時，該流動稱為急變流。流體隨著溫度的升高體積膨脹、密度減小的性質，稱為流體的膨脹性。</p><div
