pvc plastic extruder maintenance and routine maintenance

Core Tip: pvc plastic extrusion machine from the day before the start of production work, we must bear a variety of dynamic load. Various parts of the transmission due to wear and tear, melt and decomposition of gas corrosion, environmental pollution
Pvc plastic extruder from the day of investment in production work, we must bear a variety of dynamic load. Due to wear and tear of work drive, corrosion of melt and decomposition gas, environmental pollution and mistakes of operating methods, the work performance and working efficiency of each part should change or decrease slightly after working for a period of time. The purpose of maintaining and maintaining the equipment is to extend its useful life so as to keep its working performance and production efficiency in a normal condition for a longer period of time so as to enhance economic benefits. Pvc plastic extruder maintenance can be divided into routine work and regular maintenance (month, quarter, year) maintenance.
Extruder routine maintenance refers to the normal production of the extruder in each production shift operators on the extruder maintenance inspection. Such as after the succession of equipment lubrication, fastening loose nuts, scrub oil on the equipment and so on. These operations are also part of the extruder operating procedures, so the plastic extruder operator to seriously implement the operating procedures t according to the order of production operation required is one of the elements of the equipment for better maintenance.
First, pvc plastic extruder extruder routine maintenance focus
① always check the purity of the raw materials used, do not allow sand, metal powder and other foreign matter mixed into the raw material into the barrel.
② often check the lubrication parts, filling lubricants, bearing parts work temperature rise should not exceed 50 ℃.
③ barrel must have sufficient heating time, do not allow raw materials below the process temperature under the conditions of car production.
④ screw work, to low-speed start, work for some time, all normal work and then increase the screw speed.
⑤ When there is no raw material in the machine, the screw is not allowed to run for a long time, the screw idle time should not exceed 2 ~ 3min.
⑥ often observe the screw drive motor ammeter pointer swing changes, such as the emergence of a long time (allowing instantaneous overload) overload motor work, it should immediately shut down, check
