JDMY-6 axial flow fan
Product introduction
This product is the latest design by the Shanghai Jiao Tong University, developed to surpass the world's advanced level of a new generation of products, and through technical appraisal in 1986, this product identification test aerodynamic performance index according to the national standard of GB1236-76, the noise characteristics in accordance with the provisions of the national standard GB2888-82. Identification and testing of the product performance indicators have reached or exceeded the original design indicators (with the conclusion of the organization identification unit). The test identified by Shanghai Institute of mechanical engineering, Shanghai Chemical Engineering Design Institute, Shanghai City Construction College Hospital seven, seven, four Research Institute of Shanghai Jiaotong University, Department of power engineering, Tongji University, Institute of acoustics, Shanghai Municipal Environmental Protection Bureau, Shanghai General Machinery Research Institute, Shanghai City Bureau of labor protection unit of Professor, associate professor, senior engineer, engineer in. Shanghai special steel pipe factory, construction and installation company, a steel plant and other units attended the trial and will provide the user identification report.
Two, product features
The product will be identified as follows:
1, the fan flow part of advanced design, reasonable structure, wide range of working conditions, light weight, wide application, energy saving and other advantages.
2, under the design conditions of the fan, the fan efficiency of 88.8%, the noise level of 80.3dB (A), than the A sound level of 24.6dB (A), the weight of 110 kg. Compared with the similar products known as West Germany, Italy, Denmark, Sweden, Japan and other countries have reached and exceeded some of their performance indicators. To this end, it is concluded that the aerodynamic and noise performance of the fan is equivalent to the advanced level of similar products in the early 80s.
3, ZFMY-6 type fan air volume, energy saving, low noise, pressure head, medium range, material saving, suitable for smelting, steel rolling, furnaces, slipway and other high temperature post and ventilation pipe for cooling. During the trial by the user. The significance of labor protection and environmental protection. The product has been produced by the factory, put into production, advanced equipment, reasonable technology, strong technical force, the products have passed the performance test and quality inspection. Our business objective is: to ensure the quality of the implementation of three packs, abide by the contract, delivery in a timely manner, welcome the user to negotiate a letter.
Three, the use of Maintenance Notes
1, before installation and use should check whether the fan packaging, transport improper deformation damage. If the defects need to be repaired before installation.
2, to check the installation of the fan when the connection is loose, the gap between the blade and the fan should be uniform, not rub.
3, fan installation, the weight of the ventilation pipe shall not be added to the cabinet, the installation of the wind pipe should be additional support. If the air inlet is not connected to the pipeline should be installed when the collector (Bell) to improve the flow of gas.
4, post fan when in use, the fan should be placed smoothly, as fan use, flat base should be a natural fit with the foundation, should add pad pad, do not beat the flange or connected to prevent deformation.
5, after the installation of the fan, the impeller must be first to check whether there is too tight or rub phenomenon. Impeller should be flexible rotation, before the trial operation
6, according to the requirements of the correct connection power.
7, pay attention to check the direction of rotation of the impeller should be consistent with the direction of the barrel arrow, not reverse operation.
8, the ventilator is used for a long time and then re-use, but also to conduct a comprehensive inspection and commissioning, and then put into normal operation.
9, the ventilator in normal use should be regularly checked monthly. Always pay attention to the fan in the operation of abnormal sound, vibration and excessive current phenomenon, found that the problem needs to be repaired in a timely manner, in order to extend the service life of the fan.2, the main performance parameters:
