GR202系列染色机是我厂在总结多年来生产染色机经验的基础上，结合近年来纱线染色的新工艺、新技术以及各客户的新要求，博采国处*染色机长处而开发的立式圆筒形全充满式的高温，高压纱线染色机。
该产品主要适合在140℃以下对棉、毛、麻、涤棉、涤等天然纤维及其混纺织物的绞纱、筒子纱进行染、煮、漂白、清洗等工艺处理。
该机与以前常规染色机相比较，其突出优点为：
一、优良的高效率、高抗汽蚀性的混流泵。其染液正反循环通过泵内的换向阀自动完成，泵内叶轮能为染纱过程提供大流量和足够扬程系数，其穿透性强，适染高难织物，被染织物色牢度高，具有很好的匀染效果，适染多种织物。
二、该机亦具有拉链、粘扣带、花带等织物的染色功能，可谓一机多用，对织物完成漂染工艺要求，适用性广，染色色光度好。
三、自动化程度高，工艺重演性好，操作使用方便：因为该机配备电脑控制，使染色操作过程自动化，减少手动操作而引起的人为因素。染色过程*按照工艺要求运行，各功能、指令由电器系统程序控制，使工艺具有重演性，减少缸差。
四、合理、完善的操作环境和高度的安全性：该机采用自封式锅口密封，气动式锅口锁紧联动安全装置，且气动式锅盖启闭装置，使用方便，安全可靠。
各管口采用气手两用阀门，锅内的盘管，加热冷却系统均采用自动控制，劳动强度低，操作环境舒适。
GR202 series dyeing machine is the vertical cylinder type ful filling high temperature & high pressure dyeing machine for yarns,which is dereloped by our factory on the basis of srmmarizing experiences on producing dyeing machines,combining with mew process,new technology and new requirements of variors customers on yarn dyeing,ａnd absorbing advantages of foreign advanced dyeingmachines.
Thes product is mainly suitable for process trestment(such as dyeing,boiling,blanching and cleaning,etc.)under 140℃ for cotton,wool,hemp,polyester cotton snd polyester fiber,etc.matural fiber,ａnd reeled yarm & cheese of thier blend fabric.
Comparing with previous normal dyeing machine,its ortstanding advantages are:
1.Adopt the mast advanced mixed flow prmp(with excellent high efficiency and high cavitation resistance performance)of mewest desigh currentlu inChina.The direct&reverse circulation for dyeing is executdd by change valve inside the prmp.The impeller inside the pump can provide large flow andemough head coefficient for yarm dyeing puocedure.Due to its strong prnetrability,it is with high color ftstness and jood uniform dyeing effects.
2.This kind lf machine mas dyeing function for fabric of chains,glueing ribbon and printing ribbon.One machine has several functions ,it can meet the techologicsal.requirements of fabric,It can be widely rsed and the dyeing degree is very good .
3.High artomation degree with good process repeatability and convenientoperation:Since thes machine is equipped with computer control system,the dyeing preratoncan be artomated,which reduce the effects of human factorsin manual operation,The dyeing procedurdre can beexecuted completely accordingto process requirements.Each function and ordeer can be controlled by progranm lf clectric sysytem ,thus the process is with repeatability and the cyinder difference is reduced.
4.Reasonable,perfect operating environment and high safety:This machine adopts selfsealing type sealing member for kettle,pneumatic kettlt locking interlocking safety device,ａnd pneumatic opening & closing device for kettle cover.It is with convenient operation and is safety & reliable.Each orifice adopts pneumatic &manual dual-purposevalve and the coil heating systems nside kettle are all automatically controlled.Hence,the labor strength is low and the operation environment is comfortable.

安装与调试
*布置安装位置时，除考虑机器本身机械安装的空间外，还要考虑染机周围的场地，是否能满足装缸、出缸、布放纱笼等要求以及是否有利于今后保养工作的进行。
*机器可按下法找平：气动打开缸盖、在缸口处，十字交叉水平尺检验水平，最后紧固地脚螺栓。
*排液口和卸压管的下方，均应开有地沟，使废液沿着地沟顺利排出，避免溅溢地面，腐蚀机器支架，地沟方位用户根据现场自行决定。
*调试前应检查各部位的螺栓（特别是泵底架的螺栓或调节丝杆）是否紧固，带有联轴器的泵一定要使电机与泵轴同心。
*电气设备及压缩空气控制线路的安装位置，均由使用单位根据厂房具体情况自行决定，但应方便操作，不影响纱笼的搬运。（注意：电缆切勿靠近热源）
操作运转
操作前的准备工作：
*检查各气动阀和电气位置，确使它们在装设位置与控制柜上各按钮开关一一对应。并使泵的转向正确。
*用肥皂液苏打溶液或其它适宜的洗涤剂对机器进行*清洗。
*为避免可能的残留污物给试验原料造成污斑，为此试验时先染深色，后染浅色。
*染槽内通入所需要软水，将装有被染物的染笼吊入染槽后加热到40-50℃煮炼十分钟，取出染笼排液。
操作转注意事项：
禁止在受压状态下启盖或常压状态下闭盖排液。
主泵与辅泵绝不允许在缺水情况下启动，泵在运转中如发生异常声响或其它故障时，应立即停车检修。
