真空加压铸造机AVC-II的常见故障及排除

艺辉博天堂登录_商城    行业动态    真空加压铸造机AVC-II的常见故障及排除

在日常博天堂登录点多少少会遇到设备出现故障的情况

今天博天堂登录就来讨论一下真空加压铸造机AVC-II的常见故障及排除 Common trouble and servicing methods

1、加压或者真空无法达到设定值

① 惰性气体或者真空泵供应系统有问题(可能气管断开,气缸内部故障,电磁阀故障,检查软管是否连接通畅)

② 支撑柄上的脏油阻碍了铸型室的下降。从而导致铸造室无法密封,请擦干净,使用新油

③ 支撑柄上没有油,请使用新油.

2、显示的温度不正常

① 如果真空加压铸造机显示的温度与你观察中估计的温度完全不相同时,可能是热电偶接触不良或损坏。

3. 铸桶异常

真空加压铸造机的盖子打不开,室内仍然有气体,先进行排气操作。

② 不能关闭或是关不紧,溶解室或是铸型室的O型圈放置不正确,气缸顶部没有放置好,气缸中间轴心移动不准确,气缸内气体不够,盖子锁定阀有故障.

 

4. 停电处理——当操作过程中发生停电,动作被停止,启动备用冷却水.

 

5. 异常情况处理

① 关闭设备电源  ② 启动备用冷却水。

 

6. 加热系统故障报警及处理

① 水温异常:进入真空加压铸造机的冷却水压力不足未达到0.2mpa/cm²检查输入水泵是否正常运行,拆下水泵上的过滤网清洗?;诶淙此露忍?,检查入水温度是否在30度以外,冷却板堵塞,降低进水温度和吹通冷却管道.

② 频率异常: 机器环境粉尘过多,应当及时清理,线圈短路,绕圈接头粉尘短路,线圈匝数不对.

③ 过负荷: 功率过大,线圈短路,缺相,线圈破损。
