Add a frequency converter to save more than 20% of electricity
Some time ago, cable company Hua Yongming carried out technological transformation on the air compressor in the production workshop and installed a frequency converter for the air compressor, thus greatly saving electricity consumption. The air compressor used by
cable company does not have a frequency conversion energy-saving control system. in normal production operation, no matter whether the production is busy or not, as long as there is equipment in operation, the air compressor must be turned on, thus consuming a lot of electricity. So Hua Yongming wondered if he could install a frequency converter for the air compressor and automatically adjust it according to the amount of air consumption. With this idea, Hua Yongming began to take action. He first collected the relevant information of the inverter and understood the energy-saving principle of the inverter control system. The frequency converter can adjust the load of the motor according to the amount of gas required, so that the air compressor outputs a constant pressure, and the motor will not run without load, thus achieving the purpose of saving electricity.
In order to more intuitively understand and compare the power consumption before and after the renovation, Hua Yongming asked electrician Guo Zhijian to install an electricity meter on the air compressor before the renovation. After nearly two months of monitoring, the no-load rate of the air compressor reached more than 30% , with an average power consumption of 23.4 kW hours per hour. Monitoring after the renovation showed that the power saving rate reached 24% , higher than the predicted 20% . According to this calculation, the total cost of 6300 yuan invested can be recovered in more than two months. The box for the
inverter needs to be purchased separately, which costs more than 1,000 yuan. In order to save the installation cost, Hua Yongming only bought the inverter, while the box was modified by using the switch box of the old equipment, with a heat dissipation net cover and a dust cover. It really saves every bit of cost. (Lu Chaofang and Ni Yingzhen)

The company requires to do a good job in summer safety production
The high temperature season is approaching, and the group company issued a notice a few days ago to make arrangements for safe production in summer. The notice requires all subordinate units of the company to attach great importance to the work of production safety in summer, and all production and business units should hold a special meeting on production safety in summer. According to the characteristics of production in summer, they should focus on safety risk analysis for mines, outdoor operations and high-temperature posts, and implement control measures to avoid the occurrence of safety accidents such as scalding, heatstroke and electric shock. In order to further strengthen the safety production management in the high temperature season, the notice requires the main person in charge of each production and business unit to lead a team to conduct a comprehensive inspection of the production and business premises according to the characteristics of summer production; strengthen the daily safety production inspection of key posts and special posts; timely rectify the found unsafe behaviors and hidden dangers; Strengthen the management of the storage and use of flammable, explosive, dangerous chemicals and drugs; cooling measures shall be taken for the space exceeding the storage temperature limit of articles. If it is found that the electrical equipment circuit and exhaust fan circuit are aged and damaged, replace them in time and keep the grounding wire in good condition. Do a good job in checking the fire pool, pipeline water pressure and fire extinguishing equipment to ensure that the fire fighting facilities are sensitive, intact and reliable. The high temperature in summer is also a period of frequent occurrence of heatstroke and other diseases. The notice requires all units to do a good job in heatstroke prevention and cooling, implement various relevant measures, and equip necessary cooling facilities or materials such as fans, air conditioners, ice cubes and other cooling facilities or materials according to the conditions of the production site; do a good job in the distribution of heatstroke prevention drugs, supplies and cool drinks in workshops, warehouses, construction sites and other production lines; strengthen canteen management to prevent food poisoning.
