Our Advantages

Advanced blade design:

The fans produced by our company are designed with CAD and CAM assistance, and the optimal layout of the series spectrum is formulated. The rotor profile meshing reaches the optimal state, with minimal leakage. It has the advantages of advanced structure, high efficiency, and energy conservation, fully reaching the international advanced level.

Low noise:
Due to the use of efficient advanced rotor type spectra and flexible machining systems, the gas pulse flow is greatly reduced. High precision grinding of spur gears, with an accuracy of GB10095-88 level five or above, ensures smooth transmission and significantly reduces mechanical noise. The inlet and outlet ports adopt a unique spiral design, effectively controlling gas pulsation noise.

Efficiency:
The boost is high, the single-stage compression ratio is close to the theoretical limit, the overall structure of the fan is compact enough, there is no useless clearance volume, the utilization rate of the casing area size is quite high, and the internal reflux leakage is minimal, so the efficiency is high.

Long lifespan:
Due to the existence of a certain reasonable gap between impellers, as well as between impellers, casings, and wall panels, there is no friction, and the design margin of key components is large. High grade and excellent materials are selected to greatly improve the service life of the fan. The overall service life of the fan is not less than 20 years, of which the service life of the casing and wall panels is not less than 10 years, and the design service life of gears, shafts, and rotors is not less than 50000 hours.

The precision machining of the impeller is carried out using a CNC bidirectional curved surface planer (which is a specialized equipment that can only process the impeller of Roots blower). Other manufacturers only perform rough machining on CNC shaping machines for impeller precision machining in our company.

The processed rotor parts undergo strict dynamic and static balancing. Balance level G2.5.
The rough and fine machining of the casing are both processed by the imported Taiwan Dali four-axis linkage machining center. Once successful, there is a great guarantee of geometric tolerances.
Main component inspection

For castings entering the factory, our company has a relatively strict control system. Firstly, the appearance must be clean, beautiful, and elegant. Secondly, we have hardness testing equipment that performs hardness testing and composition analysis on each batch of castings.

For ductile iron castings, we require that each batch must have a flaw detection report.
Complete machine testing

The air volume and pressure directly affect the efficiency of the customer's on-site use. For this purpose, we have established an "Intelligent Detection Center for Blower". Simulate operating conditions for each assembled blower.
The intelligent testing center for wind turbines, built with an investment of over 6 million yuan, is exclusively developed by our company through a strong collaboration between Shenyang blower research institute and the Shenyang branch of the Chinese Academy of Sciences. It is the most authoritative, professional, and high-precision fan performance testing center in China's Roots blower industry.

The testing center has a total of 15 testing lines, which can detect the performance parameters of different fans under different powers of 5.5kW-400kW, and has the ability to process more than 100 units/set per day. The engineering computer automatically collects and detects various data such as flow rate, pressure, and temperature of the blower on the inspection line, and displays them on the LCD screen for the convenience of personnel recording. The detection center automatically calculates data such as volumetric specific energy and fan efficiency, and automatically organizes, saves, and prints them, completely eliminating errors caused by human operations.

All instruments used in the detection line are designed and manufactured by the Shenyang Branch of the Chinese Academy of Sciences, with an accuracy of high precision level 0.5% (0.5%). The ultra-high precision of fan detection provides a strong guarantee for strict control of product quality; Accurate performance testing completely eliminates the phenomenon of excessive flow waste and insufficient low flow caused by inaccurate fan performance in the transportation of rare gases in industries such as chemical, food, and medicine.

Our company adopts simulated working condition experiments for every fan produced, and each fan undergoes strict testing before leaving the factory, with a 100% pass rate.
