　　I. Blower Section

　　Function: The core function of the blower is to convert electrical energy into air kinetic energy, achieving directional gas delivery, pressurization, and ventilation. Specifically, this includes: precisely controlling airflow output, maintaining stable system pressure, and providing air power for the process.

　　Applications

　　Providing combustion-aiding air supply for burners, boilers, and other equipment

　　Providing aeration and mixing for wastewater treatment ponds

　　Providing compressed air for pneumatic systems

　　Serving as a power source in vacuum paper feeding, pneumatic conveying, and other scenarios

　　Application Areas

　　Metallurgical industry, chemical plants, organic fertilizer, petrochemicals, food processing, building materials, mining, textiles, gas stations, powder conveying, wastewater treatment, etc. In CNC machine tools, blowers are commonly used for spindle cooling, electrical cabinet heat dissipation, and chip removal from the cutting area.

　　Technical Features

　　Dimensional Explanation

　　Working Principle: The rotor operates eccentrically, and the volume change between the blades achieves intake-compression-exhaust; or a centrifugal impeller rotates at high speed to generate centrifugal force for pressurization.

　　Adjustment Methods: Variable frequency speed control (mainstream), inlet guide vane adjustment (power saving of over 17% under partial load), throttling adjustment.

　　Bearing Technology: Three generations of technologies coexist: general mechanical bearings, magnetic levitation bearings, and air levitation bearings.

　　Efficiency Characteristics: Volumetric operation, flow rate varies with speed, wide pressure selection range, and minimal mechanical friction loss.

　　Vibration Control: The rotor is statically/dynamically balanced, and with the help of rubber shock absorbers, vibration hazards can be minimized.

　　Key Technical Points:

　　Eccentric rotor operation, volume change between the blades achieves intake-compression-exhaust, which is a volumetric principle.

　　Mechanical friction loss Minimal contact, with only bearings and gear pairs in contact, resulting in high volumetric efficiency.

　　The rotor undergoes static/dynamic balancing, resulting in low vibration and low noise.

　　Speed control methods include: imported guide vane adjustment (energy saving of over 17% under partial load), frequency conversion adjustment, and diffuser adjustment.

　　High-end trends include: magnetic levitation bearings (contactless, lubrication-free, long lifespan), air-suspended bearings, and single-stage high-speed centrifugal technology.

　　In 2021, domestic production of Roots blowers reached 12,569 units, a year-on-year increase of 24.64%, with the industry evolving towards high efficiency, oil-free operation, and wide coverage.

　　Impact on the industry:

　　"Dual-carbon" driving energy-saving upgrades: In 2021, domestic production of Roots blowers reached 12,569 units, a year-on-year increase of 24.64%. The industry is developing from single-stage high-speed to a full range of high/medium/low pressure ratio blowers, with high efficiency and oil-free operation being the mainstream direction.

　　Magnetic/air-suspended technology replaces traditional mechanical bearings, saving over 5% in energy and significantly extending lifespan, reshaping the blower industry landscape.

　　Domestic substitution is accelerating: Leading domestic enterprises are continuously increasing their R&D investment, narrowing the technological gap with foreign brands. Industry analysis in 2022 indicated that domestic companies are seizing the domestic market and expanding into the international market.

　　II. Power Supply Module Section

　　Functions

　　The power supply module does not have energy storage capabilities. Its core function is voltage and current conversion: converting the input power supply into a stable DC voltage required by the equipment (such as +5V, +15V, -15V, +24V, -24V, 600V DC, etc.), while also undertaking the responsibilities of transformation, isolation, filtering, and voltage regulation.

　　Purpose

　　Provides a clean and stable operating power supply for control units such as CNC systems, servo drives, and PLCs.

　　Isolates grid interference, protecting downstream sensitive electronic components.

　　Monitors the power supply status and outputs "ready," "enabled," and "fault" signals to the upper-level control system.

　　Application Areas

　　Railway, power, communications, aerospace, automotive, shipbuilding, electronic information, new energy, industrial control, fire protection, instrumentation, medical, and vehicle-mounted transportation. In CNC machine tools, the power supply module is a core component of systems such as the 840D/828D, directly determining the overall reliability of the machine.

　　Technical Features

　　Dimensional Description

　　Topology: PFC+LLC resonant (current mainstream high-efficiency solution), efficiency reaches 92%~94%

　　Power Density: Gallium Nitride (GaN) solution achieves 3.75W/cm³, 14-layer high-density PCB process

　　Interface Signals: X111 "Ready", X121 "Enable", X141 Normal Operation Output, X171 Precharge Control, X172 Startup Inhibition, X181 Power Supply Port (600V DC / 380V AC)

　　Standardization: Railway EN 50155, Communication EN 55022, Power EN 62040, Medical EN 60601

　　Development Direction: Miniaturization, Modularization, Chip-based, High Integration, High Precision, High Reliability, Low Power Consumption

　　Impact on the Industry

　　Modular power supplies are the foundation of industrial automation: without stable power modules, CNC, servo, and PLC cannot function; it is the "first mile" of the entire intelligent manufacturing chain.

　　Gallium nitride (GaN) technology is rewriting industry rules: By 2025, 500W-class GaN AC modules will be in mass production, boasting 94% efficiency, a size of only 145×61×15mm, and a weight of 182g, directly driving the evolution of power modules towards higher frequencies, higher densities, and lower temperature rise.

　　There is huge potential for domestic substitution: While Europe, the US, and Japan still hold an advantage in the high-end power module market, Chinese companies are gaining market share through design improvements and cost control, further supported by favorable policies (multiple industry support policies).

　　Environmental regulations are forcing upgrades: Certification requirements such as EU ISO 14000 and US UL are driving compliance throughout the entire product lifecycle, from production to recycling, accelerating the elimination of outdated production capacity.

　　III. Synergistic Value of the Combination

　　The blower provides pneumatic power, and the power module provides electrical power. Together, they form a "pneumatic-electric" dual infrastructure in CNC machine tools and industrial automation equipment:

　　Combined Value Dimensions

　　Reliability: Stable power module → constant blower speed → consistent airflow/pressure output → guaranteed machining accuracy

　　Energy Saving: Variable frequency blower + high-efficiency power module (94% efficiency) significantly reduces overall system energy consumption

　　Maintenance: Both are designed for maintenance-free/long lifespan, reducing downtime costs

　　Intelligence: The power module's output status signal can be linked with the blower's frequency converter to achieve closed-loop intelligent control.
