In the daily production of Beiren (BEIREN) series printing presses, the lubrication and maintenance cycle is one of the most frequently encountered issues for press operators and maintenance personnel. As a representative domestic offset press, this model features strong parts interchangeability and low maintenance costs, with electrical systems mostly controlled by domestic PLCs. If not addressed in a timely manner, it can at best affect registration accuracy and print quality, and at worst cause extended downtime.
I. Typical fault symptoms include abnormal noise from dry-running parts, excessively rapid temperature rise, lack of oil at centralized lubrication points, and sudden failures caused by missed maintenance.
II. Common Q&A
Q1: What is the most common cause of lubrication and maintenance cycle issues?
A: Mainly failure to follow the three-level maintenance schedule, or using the wrong oil grade.
Q2: What should be noted when handling this on a Beiren press?
A: It is necessary to work in conjunction with the domestic CNC system / centralized lubrication control and follow standard procedures.
Q3: How can recurrence be avoided?
A: Establish a maintenance calendar.
III. Handling steps
Execute item by item according to the daily/weekly/monthly three-level maintenance checklist.
Check and replace lubricating oil with the specified grade.
Clear blocked lubrication points.
Establish a maintenance log.
The above methods also apply to models such as the Beiren 300, Beiren 400, PZ4880, and N300. For actual operations, refer to the domestic CNC system / centralized lubrication control and on-site conditions. In complex situations, it is recommended to contact professional maintenance support through the printm.cn platform.
