The protection of offset paper is of great significance for saving energy, improving production efficiency and economic efficiency, and ensuring safe production. China's offset paper protection device has experienced several stages such as comprehensive imitation, self-design, upgrading, and intelligent development. It is worth mentioning that due to the development of microprocessor technology in recent years, it provides a hardware platform for the development of intelligent and multi-functional offset paper offset paper, which makes the offset paper protection enter a stage of rapid development. Next, let's take a closer look at what paper is on the offset paper.
The performance characteristics of offset paper: dry steam heating method, the main principle is that when adding steam to the air, it will not affect the air temperature, but if the humidification amount in the air is very high, and the machined workshop personnel and indoor environment In the case of self-heating, the temperature will rise slightly. The area of ​​the machine shop for machining is large, and the amount of humidification of the air offset paper is large, resulting in a temperature increase of 1-2 °C. At this time, it is necessary to cool down the treatment, which in turn will increase the energy consumption of the mechanical equipment.
Especially when the two seasons transition or the outdoor temperature is not uniform, the method of increasing the fresh air ratio can be used to reduce the indoor air temperature. However, if the outdoor air is dry in this season, if the wind is excessive, the burden of the offset paper will be obviously increased. As a result, the temperature in the machine shop is greatly increased, and the humidity is difficult to guarantee. On the one side, it is necessary to humidify with dry steam, and on the other side, the treatment method of turning off the refrigerant to cool down will cause great energy consumption of mechanical equipment.
By comparing the humidification methods of various offset papers, the use of gas-water mixing cold fog humidification is the best way to control the temperature and humidity with high precision machining in the mechanical manufacturing workshop. Because: the effect of spray and humidification of offset paper is not obvious, the water consumption of mechanical equipment is huge; the control of wet film humidification is not accurate enough (for hysteresis control), and the wet film itself uses hydrophilic material to filter air, dust More, long-term operation of mechanical equipment is prone to bacteria, easy to cause respiratory problems in mechanical designers; high-pressure micro-fog humidification requires a large amount of work, high failure rate and not stable enough. The gas-water mixing cold mist humidification method has the characteristics of sensitive sensitivity, strong ability to generate fine mist, and linear adjustment of spray volume. It can fully guarantee the temperature and humidity control requirements of the mechanical manufacturing workshop, and can completely replace the dry steam offset paper in spring and autumn. With significant energy savings.
In addition to the general protection function, offset paper also has self-starting, communication start and shutdown, and the functions of undercurrent, overvoltage, undervoltage, three-phase current unbalance, self-starting, etc. are available. Setting function: Intelligent type has setting button, data button and shift button. When setting the over range, it will remind the user to reset and avoid malfunction. The basic type is set by dialing or potentiometer. Alarm function: When the offset paper over-current lamp flashes alarm, the larger the overcurrent multiple, the faster the flashing, or the external alarm display function of the offset paper: press the set button to display the whole current value after pressing the offset paper, press the data. The key shows the three-phase current value. The fault code is displayed after startup and the corresponding fault indicator is on, at a glance. Communication function: realizes information transmission through serial digital interface. One host computer (PC) can connect 256 offset papers, and can set parameters for each offset paper, start and stop operation, and facilitate automatic management.
