I. Installation Environment Requirements

Site Selection

Install the blower indoors in a dry and well-ventilated area, avoiding direct sunlight or humid environments.

The surrounding area should be free from corrosive gases, flammable materials, or excessive dust. If dust is present, install a filter and clean it regularly.

Ensure the installation surface is level to minimize vibration impact on the equipment.

Foundation and Vibration Reduction

The blower's steel support frame must be fixed to a concrete foundation, with a rubber vibration-damping pad (e.g., porous rubber sheet) installed between the frame and foundation to reduce vibration transmission.

The blower's main shaft must remain horizontal. Measure the concentricity between the main shaft and motor shaft, as well as the non-parallelism of the coupling end faces, ensuring both errors are ≤0.05mm.

Pipeline Connection

Connect the air duct to the blower using a flexible hose (e.g., rubber or plastic spring tube) with a length of ≥200mm and a diameter matching the blower's inlet and outlet sizes.

Install the flexible hose with appropriate tightness to avoid twisting or deformation; the suction-side canvas hose may be slightly tighter to prevent suction.

The blower's outlet pipe diameter may only be increased, not decreased. Install an insect-proof screen at the outlet, and add a weather cap when the outlet is directed upwards.

II. Operation Specifications

Pre-Startup Inspection

Confirm no tools or debris remain inside the blower casing, and check for loose fasteners.

Close the inlet air duct gate or regulating valve to prevent loaded startup.

Check the bearing lubrication oil level, cooling water supply, and coupling condition.

Startup and Test Run

No-Load Startup: For initial startup or test runs, close the inlet air duct gate and operate without load for 2 hours (for new installations) or 30 minutes (after repairs). Confirm no abnormalities before gradually opening the gate to full load.

Current Monitoring: Ensure the operating current does not exceed the motor's rated value to prevent motor burnout.

Rotation Direction Confirmation: After wiring, briefly start the blower to check if the impeller rotation direction matches the arrow on the fan housing. If reversed, swap any two of the three-phase power lines.

Operation Monitoring

Regularly check the bearing temperature (should be <40°C), vibration, and lubrication status.

Avoid blocking the inlet or outlet to prevent motor overcurrent or equipment overheating.

If used for underwater air supply, ensure the water depth pressure remains below the maximum static pressure value specified in the model catalog.

III. Maintenance and Upkeep

Regular Cleaning

Clean internal dust accumulation (especially on the blades), filters, and silencers to prevent blockages.

Clean pipeline scale to prevent corrosion.

Lubrication Management

Replace the bearing housing lubrication oil every 6 months (except during machine repairs).

Apply 7018 high-speed grease monthly to the bearing installed in the middle of the pump cover (increase frequency for continuous three-shift operation).

Component Replacement

Bearing replacement must be performed by professional personnel. Disassemble parts in order and clean them, avoiding forced prying of the impeller.

Record all mating dimensions during overhauls to ensure original clearance requirements are maintained after assembly.

IV. Safety Protection

Electrical Safety

Ensure power supply voltage fluctuations remain within ±5% of the rated value. Install an overload protection electromagnetic switch matched to the motor's horsepower.

Use grounding wires to prevent electric shock accidents, and ensure wiring complies with standards such as EN60034 and EN60204-1.

Pressure and Dust Control

Install a pressure relief valve to automatically release excess pressure when the set value is exceeded.

Select filter precision based on site dust characteristics and replace filter elements regularly.

Special Scenario Protection

In confined spaces, enhance ventilation and heat dissipation or select a high-pressure blower that allows higher inlet air temperatures (up to 200°C).

Avoid direct installation in vibrating locations; install vibration-damping measures.
