注(zhu)(zhu)(zhu)(zhu)塑(su)机通常由注(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)系统(tong)(tong)(tong)(tong)、合模(mo)系统(tong)(tong)(tong)(tong)、液压传(chuan)动(dong)系统(tong)(tong)(tong)(tong)、电气控制系统(tong)(tong)(tong)(tong)、润滑(hua)系统(tong)(tong)(tong)(tong)、加热及(ji)冷却系统(tong)(tong)(tong)(tong)、ān quán监测系统(tong)(tong)(tong)(tong)等组(zu)成(cheng)。注(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)系统(tong)(tong)(tong)(tong)注(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)系统(tong)(tong)(tong)(tong)是注(zhu)(zhu)(zhu)(zhu)塑(su)机最主要的组(zu)成(cheng)部(bu)分之(zhi)一(yi)(yi)，一(yi)(yi)旦注(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)部(bu)分出(chu)现(xian)问题故(gu)障，将会直接影响生(sheng)产效率和产品(pin)的品(pin)质。华赞机械小编(bian)和大家一(yi)(yi)起(qi)来分析注(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)部(bu)分的故(gu)障问题有哪(na)些(xie)类型以及(ji)对应(ying)的解决处理(li)方法。

(一):不能射胶:

处理方法:

1):射(she)(she)咀(ju)有异物堵(du)塞(sai).检查射(she)(she)咀(ju)是否堵(du)塞(sai).清(qing)理或更换(huan)射(she)(she)咀(ju).

2):分(fen)胶咀(ju)断(duan).拆开法兰检查分(fen)胶咀(ju)是否(fou)断(duan)裂.更换分(fen)胶咀(ju).

3):射(she)胶方(fang)向阀(fa)(fa)卡死.检查方(fang)向阀(fa)(fa)是否(fou)有24V电压,线圈电阻15-20欧姆,如正常(chang)则阀(fa)(fa)堵塞.清洗阀(fa)(fa)或更(geng)换方(fang)向阀(fa)(fa).

4):射(she)胶(jiao)(jiao)活塞(sai)杆(gan)(gan)断.松开(kai)射(she)胶(jiao)(jiao)活塞(sai)杆(gan)(gan)紧母,检查活塞(sai)杆(gan)(gan)是否断裂.更(geng)换活塞(sai)杆(gan)(gan).

5):料筒温(wen)(wen)度(du)(du)过(guo)低.检查(cha)实际温(wen)(wen)度(du)(du)是否达(da)到该(gai)料所需(xu)的熔点温(wen)(wen)度(du)(du).重新设定料筒温(wen)(wen)度(du)(du).

6):射胶活塞油封损坏(huai).检查活塞油封是否(fou)己坏(huai).更换油封.

(二):射胶(jiao)起(qi)步声音大:

处理方法:

1):射胶速(su)度(du)起步过快.观察射胶速(su)度(du)起步快慢变化.调整射胶流量、速(su)度(du).

2):油(you)路中有空气.观察各动(dong)(dong)作是否有震动(dong)(dong).

(三):射胶终止(zhi)转熔胶时声音(yin)大:

处理(li)方法(fa):

1):射(she)(she)胶(jiao)时动作转换速(su)度过快.检查射(she)(she)胶(jiao)有否加(jia)大(da)保(bao)压.加(jia)大(da)保(bao)压,调整射(she)(she)胶(jiao)级数,加(jia)熔胶(jiao)延时.

(四):射(she)胶量(liang)不稳(wen)定:

处理方法(fa):

1):油(you)缸油(you)封(feng)(feng)磨损.观察(cha)压力表压力保持情况.更换油(you)封(feng)(feng).

2):分(fen)(fen)胶咀,分(fen)(fen)胶圈磨损.用2次射胶检出.更换(huan)分(fen)(fen)胶咀三件套.

3):料筒(tong)磨损.用2次射咀检出(chu),拆料简检查(cha)磨损情况.更(geng)换(huan)熔胶筒(tong).
