Major Components / Design & Construction Features
Volute Casing
Casing Construction
Casing Design Analysis
Material Selection
We carefully select the construction material based on your specific application requirements. Among the commonly used materials are Carbon Steel, SS 304, SS 316L, SS 316Ti, Duplex, and Super Duplex steel. Each material undergoes thorough laboratory testing to ensure that its chemical and physical properties align with the specified composition.
Fan Impeller
Impeller Construction
Impellers are manufactured using advanced techniques tailored to the flow rating. Smaller flow-rated impellers are typically 3D metal printed, while larger flow-rated ones are fabricated. The blade profiles also vary, with larger impellers featuring 2D profiles and smaller sizes employing 3D profiles. The design of the blades, including their shape, curvature, number, and angles, is meticulously chosen to optimize compression efficiency. Our focus on aerodynamic efficiency minimizes losses arising from turbulence and flow separation. Comprehensive Computational Fluid Dynamics (CFD) simulations are conducted to analyze flow patterns and fine-tune impeller designs, resulting in enhanced compressor performance and energy efficiency.
Material Selection
Material selection is driven by specific application requirements, with an emphasis on excellent mechanical properties. Commonly used materials include SS 304, SS 316L, SS 316Ti, 17-4 PH steel, Duplex, Super Duplex steel, and Titanium. Rigorous material inspections are conducted during manufacturing to ensure the absence of defects or flaws that might compromise the impeller’s integrity. Quality control measures, such as non-destructive testing (NDT) techniques like ultrasonic testing and dye penetrant inspection, are employed to verify the structural soundness of the impellers.
Stress Analysis
Finite Element Analysis (FEA) is a standard practice to evaluate the stress distribution and deformation of impellers under various operating conditions. This analysis helps identify potential stress concentrations and fatigue-prone areas. By optimizing the impeller’s design based on stress analysis results, we enhance its reliability and safety.
Balancing and Rotodynamic Analysis
Each impeller undergoes dynamic balancing post-fabrication and inspection to mitigate unbalanced forces and vibrations, ensuring smooth operation. Additionally, a rotating train analysis is conducted using rotodynamics to determine the critical speeds of the impeller and the entire rotating train. This analysis ensures that these critical speeds do not intersect with the normal operating speed range, guaranteeing safe and efficient operation.
Gland Seals
Gland seals feature an innovative floating seal design, incorporating precision-engineered carbon rings arranged within the seal housing. A Buffer gas connection, strategically located within the gland seal housing, positioned between the carbon rings, enables . This buffer gas connection typically utilizes low-pressure steam or treated water to further enhance the sealing performance. The buffer gas sealing ensures the pressure inside the casing as per the design and improves efficiency of the gland seals.
Bearings
The Bearings are, predominantly of the anti-friction type, with choice of pneumatic oil lubrication or pressurized oil lubrication. To ensure precise and reliable lubrication, each package is equipped with a self-contained lubrication system. The design features a configuration where two sets of bearings are positioned on one side of the rotor shaft within a sturdy pedestal and the fan impeller is expertly mounted on the opposite side of the shaft.
Vibration Monitoring
Each package comes equipped with a vibration monitoring system. This system includes a vibration sensor paired with a transmitter that seamlessly communicates with the control system. The purpose of this system is to continuously and diligently monitor the unit’s vibration levels and provide protection against any potential problems stemming from excessive vibration. Thereby it ensures smooth and reliable operation of equipment.
Electric Motor
The packages typically feature a direct-drive configuration, with the motor directly powering the fan. However, in specific project scenarios, we offer the flexibility of incorporating a speed step-up gearbox between the fan and the electric motor. This choice is made to align with the project’s unique requirements. Additionally, electric motor’s parameters, such as voltage and frequency, are selected based on the specific conditions at your site.

Maxwatt also offers a range of centrifugal compressors, specially designed for applications with lower vapour flow ratings, delivering a remarkable saturation temperature rise of up to 16 Deg.C.
The impellers of these compressors are meticulously crafted using cutting-edge technology, including precision machining from solid forgings or state-of-the-art 3D metal printing processes. These impellers can be configured in both closed and open types, offering versatility to match your unique needs.
In our design, a step-up gearbox is typically incorporated, with the impellers securely mounted directly onto the gearbox’s output shaft. The input drive shaft is connected to an electric motor, ensuring efficient power transmission.
For specific cases demanding direct drive solutions, we offer the option of employing a high-speed motor, further expanding the range of possibilities to suit your requirements.
