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(duì)三種初始流量、三種管長(zhǎng)關(guān)閥實(shí)驗(yàn)時(shí)泵系統(tǒng)瞬變計(jì)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(duì)系統(tǒng)在三種初始流量、三種管長(zhǎng)情況下進(jìn)行三種閥的關(guān)閉實(shí)驗(yàn)和在三種初始流量、三種管長(zhǎng)情況下進(jìn)行管路切換實(shí)驗(yàn),對(duì)這些條下閥調(diào)節(jié)引起的系統(tǒng)瞬變進(jìn)行實(shí)驗(yàn)研究。
