China Drying News In 2012, Shanghai Petrochemical's PPE (polypropylene plant) extruders had only 66 times fewer than the same period of the previous year, a decrease of 37.74%. The number of waste grades decreased by 152 tons year-on-year, representing an increase of 881,600 yuan.
For the polypropylene plant, although the extruder of the granulation system stops only partially, it will produce a large number of waste defective products each time it is parked, directly affecting unit production and energy consumption. Under the background of reducing costs and increasing efficiency, in 2012, the installation started from a small place and included the “reduction of the number of extruder shutdowns†as an annual “open source efficiency increase, cost reduction and fee reduction†target.
To this end, the device convenes two monthly special sessions to analyze the operating conditions of the extruder stage, evaluate the "health index" of the extruder operation, and look for problems that affect the operating cycle of the extruder, and formulate solutions one by one. In the week, the device must propose and adjust the contents of the extruder overhaul in a planned manner. According to the principle of “the exchange must be changed, the repair must be repaired, and the repair must be repairedâ€, the predictive maintenance plan is implemented to get rid of chance; every day, the device leads and Technicians will take care of the extruder. A "cold" will arrange a "consultation."
In addition, the device will not miss every time the opportunity to repair the gap, as long as the "slit" will be inserted into a needle, "lack of ride", greatly reducing the "little fault" parking phenomenon. From January to December, the total number of hidden risks that may cause the extruder to stop and affect the long cycle operation of the extruder was found and eliminated.
The equipment has strengthened regular maintenance standards and improved maintenance requirements. It has not only strengthened the lubrication management of rotary equipment such as centrifugal dryers and suction fans in the extrusion area, but also improved the regular replacement of filters and filters, related pumps and fans. The periodical switching system has been improved; the “Performance Assessment Method of the Extruder's Long Cycle†has been improved, and the performance evaluation of the long cycle operation of the extruder has been strengthened, which has promoted the drop in the number of times of the shutdown of the extruder; the party branch of the device has been squeezed out. The organization organized an on-site meeting to solve the repetitive failure of the pelletizing water of the extruder, eliminated three security risks, and played the role of the party branch's fighting bastion.
