Rapid development lifting machinery boost the development of inverter productsby Sandy T. ECVV Online Marketing
The rapid development of the lifting machinery greatly promote the application of automation products in the industry. Automation products are used in the the lifting machinery electronic control system, including the four major categories of the PLC, HMI, low voltage inverter and low voltage electrical.
Among the crane AC induction motor speed control method, frequency control has high performance, good speed range, good stability as well as high operating efficiency. By the inverter to control the motor, the closed-loop control, the external load and the speed of change in perception by the sensor, computer-controlled inverter to adjust the speed and power output of the motor, and always in the most optimal way to control the power input of the motor, thereby to achieve the purpose of energy saving. In terms of the purpose of the whole crane, AC variable speed technology applications is up to 25 to 40% of energy saving.
Crane frequency control has been partially used in China, but popularity is not wide enough. It occupies most of the market share. Foreign inverter manufacturers occupy a dominant position. In terms of the leading level of domestic manufacturers, Shenzhen Invt Electric Company and Shanghai STEP are well known.
Lifting transport machinery industry association organized related experts to work on Motor Co., Ltd. developed "AS700 Series four-quadrant HAECO special frequency inverter products" on Sigriner new technology appraisal of the convening of the new products. The group by listening to the product development of the project task force report, the testing department and use unit test reports, the Shanghai Science and Technology Information Institute Novelty, reviewed all the technical documentation of the project site field trips to a variety of ways to give a new and up to The height evaluation: The product is part of the technical performance is superior to similar products at home and abroad. The frequency converter has reached the international advanced technical level generally recommended lifting equipment put into use as early as possible in the port market.
The "Twelfth Five-Year Plan" period will be the key to the transformation of China's economic development stage, lifting transport machinery industry as the basis of all walks of life development industry, despite the the automation applications overall level of the lifting machinery industry in China is not high. Manufacturers of lifting machinery and lifting machinery users have come to realize the advantages of the application of automation products. We also look forward to seeing more automation vendors in the rise of the lifting machinery industry, power lifting and transport machinery to catch up with the world advanced level.
