Main characteristics of Dagang high-pressure blower

1. Shell material: Made of die cast aluminum, which is the same aluminum material as Mercedes Benz wheel rims. Compared to ordinary aluminum alloys, die cast aluminum is stronger and has a lighter weight effect compared to iron shell fans.

2. Motor performance: Taiwan, China motor is used. The motor is a wide frequency, wide voltage motor. It is listed as follows: single-phase 110V/230V industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted at 45-75HZ, and IP55 protection class F insulation class. Its advantage is that the process is relatively good, and it is favored by customers at home and abroad.

3. Fan oil seal: German MERKEL oil seal is used, and the German MERKEL material is made of fluororubber that can withstand temperatures from -25 ℃ to 300 ℃. Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan.

4. Fan bearings: The core components adopt German SKF and Japanese NSK brand bearings, which can withstand 350 degrees Celsius. Compared with other brands, the bearings have stable performance, low noise, maintenance free, longer service life, and can ensure longer operation of the fan.

As a high-performance pneumatic device, its performance characteristics can be summarized as follows:

1、 Structural design and durability

Material and Craftsmanship

The casing is made of die cast aluminum material (the same level of aluminum material as Mercedes Benz car wheels), which balances durability and lightweight.

The blower and motor casing are separately die cast and both are formed by precision die casting of aluminum alloy, with stable structure and strong resistance to mechanical stress.

Core components (such as bearings and oil seals) adopt international brands:

Bearings: German SKF or Japanese NSK brands, capable of withstanding high temperatures of 350 ℃, with a long service life and maintenance free.

Oil seal: Made of German MERKEL fluororubber material, with a temperature resistance range of -25 ℃ to 300 ℃, ensuring sealing performance.

Protection level

The protection level reaches IP55, effectively preventing dust and water from entering, and adapting to harsh environments such as humid and dusty industrial scenes.

2、 Power and operational performance

Motor characteristics

Taiwan, China wide frequency wide voltage motor is adopted, which supports single-phase 110V/230V and industrial three-phase 220/380/415/660V voltage. The frequency adjustable range is 45-75Hz, which can flexibly adapt to different grid environments.

The insulation level is F level, and the motor power is consistent with the fan power (such as the 0.9KW version matched with a 0.9KW motor), ensuring efficient matching.

The speed remains stable at 2800 revolutions per minute, providing continuous and stable airflow output.

operational stability

The internal structure design is reasonable, the heat dissipation performance is excellent, and it supports continuous operation 24 hours a day to avoid overheating problems.

Adopting efficient and energy-saving technologies to reduce energy consumption and long-term operating costs.

3、 Noise and vibration control

Low-noise design

Equipped with integrated noise reduction facilities, the low-noise motor operates directly, and the fan blades are balanced and calibrated by computer and high-precision mechanical processing. The operating noise is ≤ 70dB (A), suitable for noise sensitive places such as laboratories and factories near residential areas.

The vibration value is extremely low, reducing the impact on surrounding equipment.

Seismic resistant structure

Special shock-absorbing foot base design, combined with aluminum alloy die-casting body, further reduces operating vibration and extends equipment life.

4、 Functionality and application flexibility

Installation method

Can be installed in any horizontal or vertical direction, supports compressed air supply or vacuum function, and adapts to different scene needs.

Application field

Industrial field: processes such as gas transportation, pressurization, and vacuum extraction.

Environmental protection field: sewage treatment aeration system, waste gas treatment equipment.

Food processing: Gas control during packaging and transportation processes.

Other fields: electronic production equipment, beverage industry, rubber machinery, coating industry, etc.

Special scenarios: auxiliary gas sources for circuit board printing, surface mounting, testing, and other processes, or high load wastewater treatment (such as electroplating industry).

5、 Maintenance and after-sales service

Maintainability

The structure is simple, and the core components (such as bearings and oil seals) are designed to be maintenance free, reducing the risk of downtime.

When the fan blades rotate, they do not come into contact with any parts, are lubrication free, free of oil and gas pollution, and reduce maintenance costs.

after-sales service

Provide comprehensive after-sales service and technical support to ensure the stability of the equipment during long-term operation.
