Product Applications and Demonstrations
Specializing in the R&D and manufacturing of refrigerant pumps and thermal management systems.
Product Advantage – Fully Enclosed Internal Gear Pump
System applicationFully enclosed structural design
The patented technology of a fully enclosed electro-hydraulic integrated drive pump, developed through independent innovation, virtually eliminates the risk of leakage. The pump’s structure is more compact and boasts high pressure resistance, with low vibration and noise levels, excellent heat dissipation, and high operational efficiency.
Patented Profile Technology
Through core technologies such as optimized rotor profile design and programming algorithms, the lubrication area and load-bearing capacity of the rotor are enhanced, while dead volumes and cavitation are eliminated. The resulting pump exhibits excellent performance characteristics, including high efficiency and a low net positive suction head (NPSH).
High-efficiency inverter motor
By designing a new fully submerged device that uses a pump to circulate liquid briefly around the exterior of the motor, carrying away heat and then boosting the pressure at the pump outlet, it is possible to effectively reduce the motor’s temperature rise, thereby extending the machine’s service life.
Low-noise operation control
By optimizing the flow passages and contour lines, we achieve a balanced state for the internal components, thereby reducing fluid noise caused by the alternating high- and low-pressure zones within the pump cavity. Additionally, we carefully select noise-reducing composite materials and rationally arrange the internal structure to effectively minimize operational noise.
Friction Pair Optimization Design
By optimizing the design of friction pairs and selecting the best material combinations for mating parts, we can enhance the compressive strength of the lubricating film, thereby improving wear resistance, reducing the coefficient of friction, boosting mechanical efficiency, and maximizing effective power output.
Modular Integrated Manufacturing
Based on the modular building-block principle, ensure precise positioning of internal core components and achieve standardization in sectional manufacturing. By rapidly detecting key product metrics, while maintaining a high yield rate for mass production, we can improve product energy efficiency indicators.
High-precision machining breakthrough
By controlling with high-precision equipment, the machining allowance after assembly is reduced, enabling a highly precise and consistent forming process technology. This ensures the coupling accuracy of the core rotor and effectively enhances the pump’s reliability and service life.
Fully automatic intelligent assembly
The fully automated, intelligent assembly line meets the product’s requirements for assembly accuracy and process quality, effectively enhancing production capacity and manufacturing stability, and significantly boosting overall production levels.
Product Advantage – Fully Enclosed Centrifugal Refrigerant Pump
Continuous pulsation-free conveying
The centrifugal refrigerant pump achieves smooth, continuous flow with no pulsating disturbances, ensuring stable operation of the refrigeration system and preventing temperature fluctuations caused by flow variations.
Structural optimization design
The impeller is arranged symmetrically, effectively balancing axial forces and significantly extending the pump’s service life. The pump body features a simple structure with no complex transmission components, resulting in zero wear and a low failure rate.
Runs smoothly and quietly
Fully enclosed and completely silent design, featuring low vibration and minimal noise (≤57 dBA), which causes little disturbance to the overall system operation and ensures a quiet and reliable cooling environment.
High refrigerant compatibility
It is compatible with a variety of mainstream non-conductive refrigerants, including R134a, R410A, R22, R407C, R410A, R1234ze, and R515b, meeting the needs of different systems.
Wide operational adaptability
Wide temperature range (-40°C to +80°C), wide pressure rating (up to 45 bar), suitable for altitudes up to 5,000 meters, and equipped with dustproof, waterproof, and sand-resistant features, making it adaptable to a variety of challenging operating environments.
Feature customization
It can accommodate low-level installation of the storage tank (H ≤ 100 mm) and enables full-capacity two-phase gas-liquid flow transportation (gas content s ≥ 20%), significantly enhancing system adaptability.
Wide flow pressure range
The multi-stage pump features a symmetrically arranged structure and allows for wide-range frequency adjustment (100–350 Hz), enabling flow rates from 0.6 times the rated flow rate (Qrated) to 1.5 times the rated flow rate (Qrated). The pressure can range from 2 bar to 8 bar.
Inducer Optimization Design
An inducer wheel can be installed upstream of the primary impeller, allowing the storage tank to be mounted at an installation height close to zero. This significantly reduces the required installation space and lowers the consumption of copper tubing, thereby reducing the overall system cost through optimized inducer wheel design.
Two-phase gas-liquid flow transport
A variety of impeller configurations are available to enable the transportation of gas-liquid two-phase flow (gas phase content ≤20%).
