常州WRY熱油泵,導(dǎo)熱油循環(huán)泵ら經(jīng)營有法有道【常州市武研熱油泵有限公司】常州WRY熱油泵*必須汽蝕余量的物理意義是表示液體在泵進(jìn)口部分壓力下降的程度,也就是為了保征泵不發(fā)生汽蝕,要求在泵進(jìn)口處單位重量液體具有超過汽化壓力水頭的富余能量。必須汽蝕余量與裝置參數(shù)無關(guān),只與泵進(jìn)口部分的運(yùn)動(dòng)參數(shù)有關(guān),這些運(yùn)動(dòng)參數(shù)在一定轉(zhuǎn)速和流量下是由幾何參數(shù)決定的。常州WRY熱油泵,導(dǎo)熱油循環(huán)泵ら經(jīng)營有法有道。常州WRY熱油泵,導(dǎo)熱油循環(huán)泵ら經(jīng)營有法有道。Must be the physical meaning of the margin of the liquid in the pump inlet part of the pressure drop, that is, in order to protect the pump does not occur cavitation, the pump inlet unit weight of liquid has more than the pressure of the head of the excess energy. The cavitation allowance is not related to the device parameters, but is related to the movement parameters of the pump inlet, which is determined by the geometrical parameters in a certain speed and flow rate.
