Pre press has been widely used in the plate industry. The operation process is simple, which can save a lot of energy and time, create good benefits for the development of plate manufacturers, and reduce the cost of plate manufacturers. The maintenance of the pre press is also a cost saving thing for the plate manufacturer, which can prolong the service life of the equipment, reduce the occurrence of faults and the frequency of equipment replacement.
After using the precompressor for a period of time, there may be some impurities in the equipment that may affect the normal operation of the product. At this time, it is necessary to clean and maintain it. Before cleaning, it is necessary to unplug the power cord, and then ask professional personnel to carry out the maintenance process. For some gears or parts that are easy to wear, apply lubricating oil. In addition, the surface quality of the equipment piston is good Under the condition, it is necessary to replace the worn sealing ring in time, so as to extend the service life of the equipment better and avoid some situations at the same time.
Confirm that the equipment can operate normally by pre press, and confirm the temperature, pressure, time of hot pressing and the model and specification of products to be hot pressed after no error. Put the products to be hot pressed evenly on the aluminum plate of the high temperature resistant cloth, and then cover the products with the high temperature resistant cloth. In the precompression layer of the precompressor, close the door of the hot pressing box. Press the start button of the oil pressure cylinder, that is, the start of the preloading action, and the time setting starts timing after the rise is in place. When the preloading time is up, it will automatically descend, and the hot pressed products can be taken out.
If it is found that the product cannot operate normally, it is necessary to immediately cut off the power supply for maintenance. If it cannot be repaired, it is necessary to return to the manufacturer for maintenance, so as to ensure that the machine will not have greater problems and bring us more losses.
