2) This type of fan can be manufactured in either left-hand or right-hand rotation.
3) Exhaust outlet position of the fan, indicated by the outlet angle of the housing.
4) The fan is driven by a C-type belt drive.
5) Example of full product name: Y6-41№12c Right 90° Y6-41№12c Right 45°
2. Structural Features of GY6-41 Series Centrifugal Draft Fans for Boilers
1) This series of fans utilizes advanced patented technologies, including high-strength wear-resistant impellers, oil-tight bearing housing, and articulated axial adjustment gates.
2) Wide efficient operating range with closely arranged fan models, making it easy to select an efficient operating point.
3) Utilizes adjustable inlet air openings. This means adjusting the axial and radial gaps between the inlet and the impeller during the fan installation.
4) High-intensity wear-resistant impeller. The impeller features backward curved single blade design, reducing air flow impact and ensuring good stability. This prevents motor overload and significantly extends the blower's lifespan. The model boasts a high pressure coefficient, low peripheral speed, and low noise, making it highly practical.
5) Leak-proof Oil Bearing Housing. The overlapping oil ring design effectively directs the oil from the high-speed rotating bearing to the inner wall of the bearing housing and back to the oil sump. The semi-open aluminum oil seal facilitates maintenance and prevents friction accidents, while also increasing axial resistance to reclaim some of the thin oil back to the sump. The outer pressure plate prevents a small amount of thin oil from escaping. A vent plug on the upper part of the bearing housing reduces the slight positive pressure inside, ensuring no oil leakage and excellent dustproof performance.
6) Articulated Axial Adjustment Gate. The gate features articulated bearings at the pivot point of the guide blades and the adjustment rod, ensuring there are no "dead spots" during operation and adjustment. This allows for flexible and easy adjustment, safety and reliability, and guarantees that the actuator does not overload.
7) The fan is available in either a monoblock or split assembly. For this series, the transmission group, coupling cover, and motor are assembled on a complete base before shipment for sizes 16d and below; the housing, inlet, and regulating door form another assembly. Small-sized fans are shipped as two assemblies, while large-sized ones are disassembled into multiple components for easier transportation and installation.
8) This fan features an overhanging structure for easy installation, equipped with wheels for transmission connection, evenly transferring torque, and reducing vibration for reliable operation.
9) The fan is easy to install and maintain. It features two complete base shells and a drive assembly. The shells have a central dividing surface or a vertical dividing surface, making disassembly and assembly particularly convenient. The rotor can be vertically lifted out, and can also be assembled or disassembled axially if only the impeller needs to be replaced.
