Under normal circumstances, when the equipment can not meet the process requirements, without careful analysis and research, all the factors are attributed to one point: any increase or increase of some mechanical or electrical equipment with reasonable surface. When these increased or increased equipment is put into use, it does not increase the output of the original equipment to offset the cost of energy consumption of the new equipment. Instead, the energy cost of adding new equipment is higher than the cost of the original production.
For example, if you run it daily without modification, you can use the next process. The coarse powder of the mill is fed into the grinding head by means of a material pipe. Since the wind lock problem of the material pipe affects the process parameters of the mill system, it has not been solved. Therefore, it is necessary to modify the wind lock of the coarse powder tube of the mill, and use the screw conveyor instead of the material tube to feed the coarse powder into the grinding head. Since the amount of return is not calibrated, the power of the selected screw conveyor with the motor is 189. After being put into use, the conveying capacity of the screw conveyor is too small to meet the normal production of the mill, resulting in a decrease in the output of the mill. It is necessary to extend the start-up time to meet the demand for coal powder in the next production process. The main motor of the mill has been increased from the original running time. The power consumption of pulverized coal has increased significantly and the cost has increased. After re-equipping the 89 motor, the mill output reached 567 and was run daily. But the problem of invisible waste of energy has not attracted attention. For this we can conduct a cost analysis. The power consumption is a suitable value when the screw conveyor is not added. After adding a motor of 89, the mill output is still 567. Run every day, electricity consumption every day. Pay more for electricity every day. The monthly electricity bill is calculated on a monthly basis. The electricity bill has little effect on the whole company, but there may be many similar situations for a company. With the increase, the equipment will inevitably increase their workload for the post maintenance workers, and the maintenance cost of the maintenance department will also increase. Therefore, when we are transforming the production equipment, we should carry out sufficient analysis, and we can achieve the purpose without using energy-consuming equipment. Do not use such equipment. For example, in the above example, the return pipe locks the wind problem. If the lock air lock is not good, can it be added again? The opening and closing time of one lock damper is staggered, one open, and the other is closed, which can also meet the process requirements. In short, we should pay attention to energy-saving problems in the actual production process. We should not always stare at the problem of obviously wasting energy. We should pay attention to whether there is an invisible and seemingly normal waste of energy in the production process of this department. If we can eliminate the phenomenon of invisible waste in our work, our products will be more competitive in the market and can make greater profits for the company.
With the rapid development of science and technology, the use of plastics in modern medicine is steadily increasing. Medical devices made from injection-molded plastics help reduce health care costs, infectious diseases and pain management. High-tech polymers are used in medical device prototyping and are often used to create improved prosthetics and devices to reduce the risk of infection. Medical plastic injection molding directly improves patient safety and the ability to save more lives. High-gloss injection molding: the basic process of high-gloss injection molding is to rapidly heat the surface of the mold with high temperature and high pressure steam before injection molding, so that the surface temperature of the molding mold cavity reaches above the glass transfer temperature (TG) of the resin plastic, and then inject the plasticized plastic melt into the closed mold cavity. During the injection phase, the mold temperature is kept constant by high temperature and high pressure steam. After injection molding, stop the air supply, blow out the steam in the tube with the air pressure of the duct, and then inject cooling water to make the mold temperature drop rapidly, until the mold is cooled and opened to take out the product.
