Talking about energy conservation and consumption reduction from maintenance

Saving energy and reducing consumption has become one of the important tasks of printing companies. Its purpose is to improve economic efficiency. Printing itself is machine, light, electricity and a variety of raw materials. The complex process of comprehensive operations, how to apply the form of communication, great benefits can be grasped. The author has accumulated a few years of experience in equipment management and maintenance, combined with the company's equipment usage, talked about the experience, for reference.
1. Do a good job of air pump repair and maintenance work, improve the structure of air pump, improve the utilization rate. With the operation of the equipment to high speed development, many offset presses are now equipped with two air pumps. Our company's two double-sided offset presses are one J2108B offset press. Both have air pumps. When the equipment is in operation, it is assisted to feed the air pump. When the equipment is stopped, the operator is too troublesome to turn off the auxiliary air pump. The air pump is idle for a long time and wastes a lot. According to the characteristics of air pump work and years of maintenance experience, the author finds that the air volume of the main air pump can be completely used for air intake and air suction, that is, a single air pump can be used instead of two air pumps, eliminating the need to close the paper collection pump when the work is stopped. The operation. The method is as follows: Remove the gas-filled plastic screw and install a duct joint.
This is a transformation to save the company three air pumps and save a lot of expenses. We use an air pump with a power of 5 KW, and work 16 hours a day in two shifts, 250 days in a year, and electricity costs 0.06 yuan. Calculated in kilowatt-hours, only one year's electricity bill can save the company 12,000 yuan, plus three air pump depreciation, maintenance, fuel consumption, etc., can save at least 125,000 yuan per year. The benefits of this transformation are quite comparable.
The vertical pumping and maintenance of the air pump are also very important. In summer, the high temperature air pump is most vulnerable to damage, so the filter should be cleaned regularly to keep the air pump clean and well ventilated. Because the air pump is frequently started for a long time, the left and right fan wheels of the air pump are often easily damaged, in particular, the fixing screws on the fan wheel are easy to loosen, and the failure rate is high. In order to prevent loosening of the fixing screws on the fan wheel, we took appropriate measures to fix the six stationary and stationary rims of the wheel to ensure that the life of the pump was extended and the maintenance cost was saved. It was not difficult to replace the fan wheel after the improvement. Just use a wheel to polish and rivet the screw.
2. Engaging in technological innovation and technological innovation Our company's folding machine is a ZY615 machine produced by Yutian, Hebei. The grid plate of the grid plate is seriously grinded, and its centerline deviates from the center of the grid by affecting the precision of one or two folds. The transformation, with a few centimeters worth of angle iron processed into a shape, so that the rules from the line into a vertical and horizontal plane, to ensure the accuracy of folding, and later replaced more convenient. The company's five folding machines are all performed by the main song, a total of 600 yuan more than maintenance costs.
When the company's new double-sided offset press was put into production, the large pin screw of the chain guide pulley on the delivery tray was broken. At that time, the work was in a hurry, and the time required to repair and rework the workpiece was long. For emergency repair, the method of repairing the screw on the screw thread at the center hole of the big shaft breaking screw was adopted. This method is quick to repair, it takes only a few minutes to complete, and the effect is good.
3. Summary After several repairs and reconstructions, the author believes that engaging in technical innovations and technological innovations will not only increase production efficiency, but also achieve significant economic benefits if they meet the mechanical and process requirements.
