The operation of 2. beaing pipeline is very lack of standardization.In the unimpeded process, often need the workman constantly to beat along pipeline, to shake loose embolism material with hard things such as hammers.Beaing the damage of pipeline like this is very big, very easily makes pipe deforming, cracking, and this behavior is should be forbidden in ordinary production.
3. increase the fatal accident potential safety hazard.Delivery duct has a lot of parts to be mounted in underground or the high-altitude, and during serious putty, the place that the workman beat or dismantled pipeline is danger close all, has increased the accident potential of some personal secure contexts virtually.
4. troubleshooting time long, influence ordinary production.Through using the repeatedly actual of a plurality of productions place, find that the unimpeded time is quite long, dismantle pipeline if desired, debugging period will be longer so, even cause the situation of next production process generation raw material breakthrough.
5. must carry out unimpeded by manual intervention, can't realize automation.After putty takes place, will interrupt by PLC or computer-controlled automatic feeding process, by operating unimpeded manually, treat that pipeline is confirmed mediation fully by the maintainer after, just can go back to auto state and continue production.
