[机械]扣管机安全操作规程

作者[孙锡云] 发表于[2011-2-25 10:47:00]

扣管机安全操作规程

 

一、适用于扣压工程机械液压油管、工业设备油管、汽车油管、水管、空调管。

二、工作原理及工作过程

扣压机构是本机工作机构。压套在油缸柱塞的带动下实现往复运动,对固定在芯轴上的弹簧压头不断压紧和放松,将装好的管头,外套、芯子放入弹簧压头中间圆孔内,开动电机、油泵、控制阀,驱使油缸柱塞运动,通过带有锥度内壁的压套,压紧带有同样锥度的弹簧压头外壁,实现压合目的。换向后,压套反方向运动,弹簧压头复原,将高压胶管接头取出。

三、使用说明

1. 油箱应加入46#长城液压油(油必须保证清洁,否则会损坏油缸及密封)达到油箱高度的75%

2. 工作前,将增大手柄放在工作位置上,启动电动机三分钟,空载往复运行二分钟,各模座均涂黄油。

3. 各油杯均加20#-30#机械油。

4. 本机在扣压胶管前,压套、19部位(导向键)、13部位(滑轮)、22部位(模座锥面)等必须用高级润滑剂(二硫化钼)涂覆,以减少磨损。特别对Φ32mm以上高压胶管的每扣压20-30根就需涂一次(每次不必太多)。

5.在扣压大法兰、大弯头高压管,不能伸进机内时,可将增大手柄至急停位置,放入后,随之将增大手柄搬至工作位置,即可进行扣压,扣压完毕搬回急停位置,调头放入,再将增大手柄搬入工作位置进行扣压,依次类推。对于一般高压胶管扣压,增大手柄放在工作位置就不用动。

6. 工作完毕,模座和压套均要擦干净涂黄油,并且模座和压套不能靠太近(以压套和模座不接触为准),最后停机,将增大手柄松开,放入急停位置,使内弹簧放松。

7. 应注意的是:开机前增大手柄一定要放在工作位置上,否则,开机前进会将机头压坏,致使本机不能工作。

四、安装与使用

1. 本机要安装在车间水平地基上。

2. 安装调试是制造厂作空载运转,并对管接头进行压合试验,确认满足设计要求后,方可出厂。

3. 扣压不同规格的胶管,应更换不同规格的压头。

4. 长期使用后发现有漏油现象时,要及时更换油缸和管阀系统中的密封件。

5. 液压油选用46#长城牌抗磨液压油,油温一般控制在30~35为宜。

6. 对压合机构的工作情况要定期进行保养,以保证设备正常运转。
