Machine preparation status detection. The state of preparation of the machine can be detected by jogging or turning. If other items such as tools are stuck in the machine; whether the plate is installed properly, if it is not suitable, it may cause damage to the plate or cause difficulty in finding the rules; Whether the blanket is installed properly, if not, it is possible Causes printing failure, which can damage the blanket or machine in severe cases.
The lubrication state of the machine. First of all, you can observe whether the oil passage of the machine is unblocked by the oil mark. If the oil mark is not oily or the oil mark is unclear, you should check the oil circuit for oil leakage. Although the oil leakage of the machine is easy to observe, it is difficult to find the cause. For machines such as plain bearings, low speed is not conducive to lubrication, especially jog or low speed operation has a greater impact on lubrication. Therefore, before performing such operations, it is best to first idling the machine for lubrication. This is also a top priority for each work before going to work. Some machines' oil pumps are driven by the main engine. Therefore, when the point is reversed, the oil circuit can not only add fuel, but will suck the oil from the oil circuit back to the fuel tank. This is very dangerous, so the reverse point should be avoided. Lubrication of some of the more important parts can also be detected by the temperature of the metal near it. If the temperature is too high, it indicates that there is a problem with lubrication.
The impact of the machine during operation. The smaller the impact during the operation of the machine, the better the printing, and the longer the life of the machine. Reducing the printing pressure (in a broad sense of pressure) is an important condition for ensuring smooth operation of the machine. Under the premise of ensuring the quality of the printed product, the printing pressure is as small as possible. Reducing the speed of the machine is another important condition for reducing the moment of inertia of the machine. The lower the speed of the machine, the smaller the moment of inertia of the machine, so the machine should not be kept at high speed. The above aspects are only part of the daily maintenance and maintenance of the printing press. The quality of the 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.
