T35-11 series axial flow fan
I. T35-11 series axial flow fan
T35-11 series axial flow fan, as a new fan updated on the basis of T30-11 in 1980s, enjoys the following obvious advantages compared with T3—11:More reasonable structure: Imitation cylindrical outline lessens flow loss, and strengthens blade root; 2. Greatly improves performance: total pressure efficiency is 89.5%, and noise (compared with level-A noise)reduces 3.6 3.6dB(A).
The series fan are applicable for transporting non flammable and explosive gas with no corrosion no significant dust under ambient temperature no higher than 60℃.It is widely used in general factory, warehouse, office, and dwelling house ventilation or strong heating radiator, and interval series-connection installation in long exhaust air pipeline is also acceptable, to increase pressure in pipeline, and it can also function as a free fan after removing enclosure.
Blades of the series fan have total 30 diameter specifications, ach of them have 4 blades, and there are five kinds of blade angles including 15°,20°,25°,30°,35°, with wide range of parameters, air quantity is 826—67892m3/h.
Fan of the series fan is composed of blade wheel, enclosure, collector, and motor, etc, of which, fan wheel is directly connected with motor, and blade direction of rotation is left-handed (from the motor)
Fan of the series fan is composed of blade wheel, enclosure, collector, and motor, etc, of which, fan wheel is directly connected with motor, and blade direction of rotation is left-handed (from the motor)
Performance parameter, overall dimension and matters to attention of FT35—11 andBT35—11 fans are same as that of T35-11.
II. Installation of T35-11 series axial flow fan
Before installation, carefully check whether fan is damaged or deformed, if it is damaged and deformed, installation shall not be conducted until well repair.
During installation, pay attention to whether joint parts are loose, and gap between blade and airduct shall be even, no collision is allowed.
Weight to connect airduct shall not be borne by airduct of fan, therefore, it is necessary to increase additional support during installation.
It is required to install current collector and protective screening at inlet of fan.
Base of fan must be naturally jointed with plane of foundation, do not beat the based to force joint to avoid base deformation. During installation, it is necessary to calibrate the base, put sheet iron under the base, and keep it at horizontal position, and next, tighten anchor bolt.
Upon completion of installation, it is required to test at first, and put into official use after smooth operation.
III. Usage of T35-11 series axial flow fan
For adoption of the fan, if it is necessary to connect pipe at air inlet, it is required to consider way of connection to lessen losses caused by diffusion of dynamic pressure of fan in pipeline.
When pipeline diameter equals to airduct of fan or Fmp/F1≤1.5 pipeline length not less than 5-8 times of inner diameter of pipeline, diffusion loss of pipeline can be negligible;
When 1.5≤Fmp/F1<2.5or Fmp/F1>2.5, it is necessary to equip with diffuser for pipeline and fan.
If use the fan in long-distance exhaust duct, fan interval can be installed in series, to increase fan pressure, however, two fans shall not be separated too far away.
