Dynamic Maintenance Of Printing Press

Dynamic maintenance
Dynamic maintenance of printing presses refers to the maintenance of the printing press when it is in a dynamic state. Static maintenance of the machine is the prerequisite for dynamic maintenance of the machine. At the same time, the dynamic operation of the machine can in turn detect the level of static maintenance of the machine. Dynamic maintenance of the machine is very important. The following will analyze the main contents that should be maintained under machine dynamics from several aspects.
1. Machine readiness status detection. The readiness status of the machine can be detected by jogging or turning. For example, tools and other items are stuck in the machine; whether the printing plate is installed in a suitable position. If it is not suitable, it may damage the printing plate or make it very difficult to find the rules; whether the blanket is installed properly. If it is not suitable, it may cause problems. Cause printing failure, which may cause or damage the machine in severe cases.
2. The lubrication status of the machine. First, you can use the oil mark to observe whether the oil circuit of the machine is smooth. If there is no oil in the oil mark or the oil mark is unclear, you should stop the machine urgently and carefully check whether there is oil leakage in the oil circuit. Although oil leakage from a machine is easy to observe, finding its cause is difficult. For machines using sliding bearings, low speed is not conducive to lubrication, especially inching or low-speed operation, which has a greater impact on lubrication. Therefore, before performing such operations, it is best to idle the machine and lubricate it. This is also a primary task that should be done before going to work every day. The oil pump of some machines is driven by the main engine. Therefore, when reverse point occurs, the oil line will not be refueled, but will suck the oil in the oil line back to the tank. This is very dangerous, so reverse point should be avoided. The lubrication of some more important parts can also be detected by the temperature of the metal near them. If the temperature is too high, it indicates that there is a problem with the lubrication. Common faults and troubleshooting methods of gravure gold and silver ink
3. Impact during machine operation. The smaller the impact during machine operation, the better it is for printing and can also extend the service life of the machine. Reducing the printing pressure (pressure in a broad sense) is an important condition to ensure the smooth operation of the machine. On the premise of ensuring the quality of the printed products, the smaller the printing pressure, the better. Reducing the machine speed is another important condition for reducing the machine's moment of inertia. The lower the machine's speed, the smaller its moment of inertia, so the machine should not always be running at high speed.
The above aspects are only part of the daily maintenance and upkeep of the printing press. The quality of daily maintenance and maintenance of the printing press directly affects the service life and product quality of the printing press, so it cannot be taken lightly.
