使用注意事项

1.尽量避免于三分钟内关闭再开启冷冻机组以免影响压缩机之功能

2.本机绝对禁止加热或测试爆炸性可燃性为高腐蚀性物质 否则会造成不必要的损失或者本机不能对其进行试验.

3.测试物放置量不可影响测试箱的风量循环否则会影响机器性能.

4.使用时门要关好关严否则温度外泄达不到性能区域.

5.指定人员操作此机以免使机器提早损坏.

6.本机运转时,应尽量避免打开箱门,因为在做低温时,苦开启箱门?#33258;?#25104;内部蒸发器及其它部位之封冰现象,尤以温度越低,状况越严重,若必须打开,则应尽量缩短时间

7.当完成运转时,待机器完全停下以后方可开门取测试品

8.于操作当中,除非?#33455;?#23545;必要,请不要打开箱门,否则可能导致以下不良后果:高温气冲出箱外十分危险

箱门内侧仍然保持高低温造成伤害

高温空气可能触发火灾警报,产生误动作

开门方法:操作人员开门时必须沿着开门方向向后移动防止机内大量热气涌出伤人.

9.请注意本机必须安全确实地接地,以免产生静电感应

10.电路短路器温度超温保护器,提供本机测试品以及操作者的安全保护,?#26159;?#23450;期检查

11.运转中,请勿以手触检查,以免触电或为风扇所伤,而发生危险,因此请先停止运转,关掉电后再修理

12.非本机职人员不可对本机进?#24418;?#20462;和检查维修检查时由专职人员进行同时要有监护人员进行监护防止未知情人员进行通电合闸造成触电伤人

保养方法

1.冷冻机组之冷凝器 (散热器)应定期保养,保持清洁?#39029;?#31896;糊冷凝器会使压缩机高压开关跳?#35759;?#20135;生误报警冷凝器应定期每月保养,利用吸尘器将冷凝器散热网片上附着之其尘吸除或开机后使用质硬的毛刷刷之或用高压气嘴吹干凈?#39029;尽?/p>

2.开关门或从炉内取测试物时不得让物品与门上胶边接触以防胶边被破坏和缩短寿命

3.机身周围和底?#24247;?#22320;面要随时保持清洁以免大量?#39029;?#21560;入机组内产生意外事故和降低性能

4.冷冻系统是本机的核心请半年巡检一次所有铜管?#24418;?#27844;漏雪种情况各嗽叭接头焊接口如有油渍外泄请通知本公司或直接处理之

5.配电盘之大电流接点配电室内每年至少清洁检修一次以上接点的松动会使整个设备处于危险工作状态轻则烧坏组件重则发生火灾报警人身伤害非常危险.清洁时清利用吸尘器将室内?#39029;?#21560;除即可

6.配电箱内的两个超温保护器设定值请不要随便调试出厂时?#35757;?#22909;此保护开关是保护加热管空焚?#36884;?#25253;之用.设定点温度设定点20桫30档

7.当试验产品时间到达后取产品时必须在关机状态下且工作人员一定要戴好干燥防电耐温手套进行取放产品.

8.箱体内外?#24247;?#28165;洁与保养

9.机器在操作前应先将内部杂质(物)清除

10.配电室内每年至少清洁一次以上,清洁时请利用吸尘器将室内?#39029;?#21560;除即可箱体外部每年必须清洗一次以上,清洗时用?#35797;?#27700;擦拭即可返回搜狐查看更多
