outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 为了保证织机正常启动与运行,主传动电动机轴头一般都为锥形。机型不同,其锥度有所不同。在使用中或更换皮带轮时,一定要保证皮带轮与电动机轴有足够接触面。</p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

为了保证喷水织机足够的启动转矩与工作转矩,主电动机皮带必须具有足够的张力。通常使用直压式张力仪称进行皮带张力检测。</p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%;

制动系统由电磁制动器、电源及控制回路组成。如图3-38所示。</p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both;

喷水织机普遍采用单片式电磁制动器(3-39)。由动片(金属摩擦材料)与静片(表面为非金属摩擦材料,内部并埋有线圈)组成。其结构简单、使用方便。电磁制动器按线圈种类分为单线圈与双线圈两种形式。沈阳宏大纺机公司(沈阳纺机厂)及丰田公司(即原尼桑公司)生产的喷水织机使用单线圈式电磁制动器;津田驹及引春公司生产的喷水织机使用双线圈式电磁制动器,即高压线圈与低压线圈。<br style="max-inline-size: 100%;

织机使用的电磁制动器其制动力矩一般在160～350N m之间。当织机的转速越高、门幅越阔时,其所需的制动力矩越大。</p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 电磁制动器使用时必须做到两个基面平行,且间距保证在0.25～0.4mm之间。使用时切忌两个摩擦面沾染油污尘埃。</p><br style="max-inline-size: 100%;
