1.喷灌软管的生产喷灌软管在工作中必须经受高张力载荷,不用时塌成瘪平形,对行走式喷灌机而言,其后方的喷灌软管在行进中形成“U”形拐弯。因此,对喷灌软管的基本要求是坚韧、可靠和易于摆弄。通常把实际工作末端拉力设计得不超过有效总抗拉强度的35％。软管在压力下的伸长有引起在拐弯处扭结的倾 Sprinkler hose production Sprinkler hose in the work must be subjected to high tensile load, collapse flat flat when not in use, for the walking-type irrigation machine, the rear of the sprinkler hose in the process of the formation of “U” -shaped bend. Therefore, the basic requirements for sprinkler hoses are tough, reliable and easy to play with. The actual working end tension is usually designed not to exceed 35% of the effective total tensile strength. The elongation of the hose under pressure causes a kink to twist at the bend
