1. Overview

This document details the technical specifications, performance parameters, and installation guidelines for Series C Casting Multistage Centrifugal Blowers. These blowers are utilized in various industrial applications including high-speed centrifugal blowers, magnetic suspension blowers, ventilation fans, roots blowers, transparent centrifugal blowers, and powder engineering transport systems.

2. Technical Specifications

Key parameters for each blower model include:

• Model Identification: Codes such as C20-1.2Z, C160-1.35Z, up to C1000-1.6Z indicating size and configuration.
• Operating Conditions: Standard suction pressure at atmospheric (101.32 kPa), discharge pressure typically ranging from 20 kPa to 98 kPa, operating speed fixed at 2980 rpm, temperature generally between 200-300°C, and air density around 1.2 kg/m³.
• Power Requirements: Axial power ranges from approximately 9.3 kW for smaller models to over 1000 kW for larger units.
• Motor Specifications: Motors vary from 11 kW to 1250 kW, with types including Y160M-2, Y280S-2, Y355L2-2, Y315L1-2, and high-voltage motors (6kV/10kV) marked with an asterisk.
• Physical Dimensions and Weight: Blower weights range from about 125 kg to over 5880 kg. Inlet and outlet flange sizes vary from DN160 to DN1250, rated at PN1.0MPa.
• Capacity: Airflow capacities span from approximately 2850 m³/min to over 11000 m³/min depending on model size.

3. Performance Data and Selection Criteria

Extensive tabulated data correlates blower models with discharge pressure, axial power, motor power, and blower weight. These tables facilitate selection based on required airflow and pressure. Key points include:

• Operating speed is constant at 2980 rpm for all models.
• Discharge pressure ranges from 20 kPa to 98 kPa depending on model.
• Motor power must be matched to axial power requirements for optimal performance.
• High-voltage motors are available for larger power demands.

4. Mechanical and Dimensional Data

The document provides detailed mechanical dimensions and foundation layouts essential for installation:

• Outline dimensions (length, width, height) are given in millimeters for each blower model.
• Foundation dimensions specify bolt hole patterns and spacing (e.g., n-M24X500, 8-200x200x700) to ensure secure mounting and vibration control.
• Inlet and outlet flange sizes and positions, rotary direction, and suction/discharge orientation are clearly defined.
• Blowers are grouped by size ranges (e.g., C20-C35, C80-C130, C400-C600, C800-C1000) with indicative dimensions; final installation drawings should be referenced from contract documents.

5. Application and Usage Recommendations

• Select blower models based on required capacity, pressure, and medium type, ensuring motor power aligns with axial power needs.
• Operate blowers at the specified speed (2980 rpm) and within temperature and pressure limits to maintain performance and longevity.
• Consider blower weight and flange sizes for installation compatibility.
• Consult manufacturer for performance conversion when operating conditions differ from standard atmospheric parameters.
• For conveying media other than air, internal anti-corrosion treatments are applied to blower casing and impeller.
• Verify foundation dimensions and bolt hole patterns carefully to ensure proper mounting and alignment.
• Refer to contract-specific drawings for final installation details to accommodate project-specific requirements.

6. Summary

This document serves as a comprehensive technical reference for engineers and technicians involved in the selection, specification, and installation of Series C multistage centrifugal blowers. It consolidates critical parameters such as power, capacity, pressure, mechanical dimensions, and installation guidelines necessary for effective system design and integration in industrial ventilation and powder transport applications.
