    摘要:

    提出搖臂式噴頭和全射流噴頭的計(jì)算公式,通過實(shí)驗(yàn)對比它們的參數(shù)。結(jié)果表明,全射流噴頭步進(jìn)角度和步進(jìn)頻率主要由導(dǎo)管長度決定,導(dǎo)管越長則步進(jìn)角度越大,步進(jìn)頻率越小。對于搖臂式噴頭,它的步進(jìn)角度和步進(jìn)頻率的可改變幅度不大,因此全射流噴頭具有一定優(yōu)越性。提出了全射流噴頭步進(jìn)角度與管長之間的關(guān)系式,左右壓差與導(dǎo)管長度和工作壓力的經(jīng)驗(yàn)公式。

    Abstract:

    The calculated equations of complete fluidic sprinkler and impact sprinkler were submitted. Their parameters were contrasted by experiments. The experimental results demonstrated that the angle and frequency of complete fluidic sprinkler was mainly depended on the pipe length. The more lengthen of the pipe was,the bigger angle and the lower frequency would be and the smaller the angle and frequency of impact sprinkler range would be. So the complete fluidic sprinkler is more superiority. At the same time the relationship of pipe length and angle of step-by-step operation was brought forward. Empirical equations of pressure difference and pipe length and working pressure were put forward for the first time.
