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)

Peak natural products among the top 20 scientific and technological innovation in TEDA

A few days ago, Tianjin Jianfeng Natural products Research and Development Co., Ltd. stood out among nearly 35000 enterprises in Tianjin Development Zone and won the honor of "Top 20 Scientific and technological Innovation Enterprises of 2015. The selection criteria for the top 20 scientific and technological innovation enterprises in Tianjin Economic and Technological Development Zone mainly include: they have won science and technology awards or patent awards in 2015, as well as other awards above the provincial level; they have obtained the qualification certification or approval of research and development institutions above the provincial level; in 2015, the number of invention and utility model patent applications and authorizations was large, totaling more than 15; in 2015, they were supported by national or Tianjin key science and technology plans; scientific research achievements have made significant progress and technology. According to the above standards, Jianfeng Natural Products Company has not only won the second prize of Tianjin Science and Technology Innovation Project Award for the achievements of "Tianjin Plant Waste Reutilization Technology Engineering Center Construction", but also completed the process research of grape seed extract and ginsenoside to pesticide residues, and formulated the international business standard of grape seed extract (grape seed oligomeric proanthocyanidins). In order to better carry out the pilot experiment, large-scale technical transformation was carried out on the second workshop, and the process optimization of extracting anthocyanins from blueberries has been carried out. At the same time, the main business income, operating profit, tax revenue and other economic indicators of peak natural products company in 2015 have increased significantly year-on-year. Relying on the advantages of excellent quality, good efficiency, great contribution, safety and environmental protection, and good social responsibility, Jianfeng Natural Products Company successfully passed the review and became one of the "Top 20 Scientific and Technological Innovation Enterprises in 2015" in Tianjin Development Zone.

Peak pharmaceutical "enterprise information construction project" through the acceptance

The "Enterprise Informatization Construction Project" of Jianfeng Pharmaceutical Company was included in the list of key projects of "Integration of Industrialization and Industrialization" (high-level and in-depth combination of informatization and industrialization) in Jinhua City in 2015, and successfully passed the on-site acceptance of the expert group on the morning of May 18. The main contents of the "enterprise information construction project" of the pharmaceutical company include: the tank farm control system, which solves the problem of closed metering and transportation of organic solvents between the tank farm and the production area, can automatically realize the terminal metering setting, and effectively ensure the safety and environmental protection requirements of the tank farm operation; The air conditioning automatic control system realizes the control of the temperature, humidity and room pressure difference in the air conditioning area through the PLC digital-to-analog conversion of the upper computer and lower computer and the terminal actuator regulator, ensure the cleanliness requirements of the production area environment; The online particle monitoring software system automatically adjusts to the standard flow through the upper computer, vacuum system, laser sensor and isodynamic sampling probe, etc. through the flow detector device and key orifice plate inside each sensor, monitors the temperature, humidity, particles, planktonian bacteria, room pressure difference, etc., implements dynamic management, and realizes visual monitoring of the production process environment. MRP production management system, it makes it easier for the warehouse, workshop, and management personnel to obtain information about the flow of materials in the production process, the implementation of production plans, and product inventory. During the on-site acceptance on the 18th, the acceptance team composed of the Information Department of the Municipal Economic and Information Commission, the Economic and Development Bureau of the Development Zone, the Municipal Information Promotion Association and professors of Zhejiang Normal University checked the contracts of each system software, purchase and transfer records, training records, and problem records in project implementation,
