The centrifugal fan is mainly composed of fan unit, auxiliaries along with the control and monitoring system. Fan unit consist of a rotor part (impeller and the main shaft), static part (housing, inlet box, air inlet), damper and etc. And the auxiliaries includes motor, hydraulic coupling, actuator and etc.
The centrifugal fans have various transmission methods, which are the motor direct connection (A type), the belt transmission (B, C, E type), the coupling transmission (D type) and the coupling transmission with inlet box (F type). Among these, the E type and F type can be designed as double suction fan types.
Upon arrival of the fan, check whether all parts are damaged or missing, and any defects and deviations should be reported to Dart-Rich
as soon as possible.
1. For the fan parts delivered in bulk, some matching parts have been pre-assembled in Dart-Rich and marked before disassembly,
packaging and transportation, and must be installed on site according to the markings.
2. It is necessary to drive the transmission part before installation after the installed ventilator of the whole machine arrives at the site,
check whether the rotating parts are rubbed or jammed, and check the coaxiality of the coupling between the fan and the motor. If there are any problems, it is necessary to adjust and correct them in time.
1,With the advanced model series, and with the optimization of the impeller and other flow channel by CFD technology, the fan is of high efficiency, low noise and wide high efficiency range.
2,Using CAE tools to verify the strength, stiffness, and rotor power of the product, ensuring smooth,safe and reliable operation of the fan.
3,By optimization, the fan structure is reasonable and easy to install and maintain.
4,By adopting various materials, and applying different technologies, we can provide fans used for many working conditions such as wear resistance, high temperature resistance, corrosion resistance and tight seal.
