Overview

This document provides detailed technical specifications, performance data, and accessory information for the MVR series of rotary blowers, including the SSR-K model. It focuses on energy-saving designs, mechanical improvements, and compatibility features for centrifugal and Roots blowers used in ventilation and powder engineering transport systems.

1. Design and Energy Efficiency

• Energy Saving: The K series blowers are developed with deep design considerations to achieve over 30% maximum and 10% average energy savings compared to previous models.
• Compact and Low Noise: The blowers feature compact designs with reduced noise and vibration through special impeller shapes, high rotational speeds, and energy-efficient belts.
• Volumetric Efficiency: Minimizing the clearance between casing and impeller reduces gas backflow, improving volumetric efficiency.
• Mechanical Enhancements: New 3-lobe impellers, refined casing structures to reduce pulsation, and specially designed suction silencers contribute to quieter operation and lower vibration.
• Compatibility: The K series maintains foundation and piping dimensions consistent with previous SSR models, enabling easy replacement without infrastructure changes.
• Maintenance Convenience: Bearings are grease-lubricated at the pulley end, eliminating the need for regular lubrication checks or oil changes. Suction silencers include lifting handles for easy filter inspection and replacement.

2. Performance Specifications

The document includes extensive performance tables for various SSR-K blower types (50K, 65K, 80K, 100K, 125K, 150K), detailing:

• Bore sizes: Ranging from 50 mm to 150 mm.
• Rotational speeds: From approximately 930 rpm to over 3000 rpm depending on model.
• Suction volume (Qs): Measured in cubic meters per minute (m³/min) at discharge pressures from 10 kPa to 60 kPa.
• Required shaft power (La): Power consumption in kilowatts (kW) corresponding to each operating point.

The tables show that the K series can achieve over 120% of the maximum flow capacity compared to previous SSR models at the same bore size.

3. Dimensional and Weight Data

Detailed outline dimensions and weights for SSR-K blower models are provided, including parameters such as length, width, height, mounting hole sizes, and weights (excluding motor weight). Dimensions are given in millimeters (mm).

4. Accessories

• Suction Silencers: Various sizes corresponding to bore diameters, designed to reduce intake noise.
• Discharge Silencers: Two types (KM and RKM) with detailed dimensions and weights to reduce exhaust noise.
• Check Valves (DCV): Specifications for check valves including bore size, dimensions, mounting details, and weights.
• Y-Shaped Reducers (YSS) and Vacuum Breakers (VOCP-B): Accessories for vacuum applications with dimensional data.

5. Vacuum Accessories

Specific vacuum-use accessories for the K series blowers are listed with bore sizes, dimensions, mounting hole details, and weights.

6. Performance Comparison

A blower performance comparison table is included, summarizing the efficiency and power consumption improvements of the K series over previous models.

Critical Information and Best Practices

• When replacing SSR models with K series blowers, no foundation or piping modifications are necessary, ensuring easy upgrade.
• Regular maintenance is simplified due to grease-lubricated bearings and easy access to filters via lifting handles.
• Special impeller and casing designs significantly reduce noise and vibration, improving operational environment.
• Energy savings are substantial, with up to 30% maximum reduction in power consumption, contributing to lower operational costs.
