The article calculates the transient of the pump system with three initial rates of flow and three kinds of pipe length by use of the characteristic method , and obtains the system ' s transient characteristics 用特征線法對三種初始流量、三種管長關(guān)閥實驗時泵系統(tǒng)瞬變計算,得到系統(tǒng)的瞬變工況特性。
Experiments were carried with under the conditions that involve three initial rates of flow , three kinds of conduit lengths jnd three sorts of valve , and the transient characteristics brought by valve adjusting were studied . for the first time does there have such an overall transient flow investigation of the whole system under valve adjusting condition 對系統(tǒng)在三種初始流量、三種管長情況下進行三種閥的關(guān)閉實驗和在三種初始流量、三種管長情況下進行管路切換實驗,對這些條下閥調(diào)節(jié)引起的系統(tǒng)瞬變進行實驗研究。
