Vigorous Screw Pumps：Special screw

In the industrial field, the performance of screw pumps directly affects production efficiency and costs. With profound technical accumulation and continuous innovation, Vigorous presents you with cutting – edge solutions for the screw rotor shaft of screw pumps, comprehensively breaking through traditional limitations and setting a new benchmark in the industry.

I. Subverting Tradition: The Outstanding Transformation of the Integral Screw Shaft

For long, the industry has seen the split – type screw rotor shaft as mainstream, yet it has inherent flaws. Vigorous bucks the trend by introducing the integral screw shaft design, a major revolution in screw pump field.

This design boosts the equivalent diameter of the screw rotor shaft’s dangerous cross – section by nearly 50%, as if giving it “reinforced bones”, and thus strength surges about 2.5 times. Also, the integral shaft gets rid of the keyway needed for the split – type one. The keyway weakens shaft strength and causes stress concentration during machining, like a “time – bomb”. Vigorous’ integral design removes this “bomb”, greatly enhancing the shaft’s stability and reliability.

II. Patented Profile: The Perfect Integration of High – efficiency and Compactness

The screw rotor profile is the core technology of screw pumps, and Vigorous has demonstrated its strong innovation strength here. The independently developed profile has obtained a patent.
This unique profile significantly improves the ultimate pressure of the single – stage screw rotor seal chamber. When reaching the same outlet pressure, the number of seal chambers of the Vigorous screw rotor is reduced by 30% compared with the traditional profile, and the length of the screw rotor part is correspondingly shortened. This not only reduces the material cost, but more importantly, the span between the support points of the screw rotor shaft is shortened by 25%, so that the deflection of the rotor shaft under the same load is sharply reduced by about 80%. As a result, the pump is more compact in size while its efficiency is greatly improved, bringing double benefits to your production space and cost control.

III. Zero Dynamic Balance: Running as Smooth as Silk

On the way to pursuing the smooth operation of screw pumps, Vigorous has never stopped exploring and introduced a rotor design with a theoretically zero dynamic balance.
This innovation greatly reduces the additional load on the screw rotor shaft, almost bringing it to zero. Under different working conditions, the horizontal load on the rotor shaft is reduced by 30% – 60%. Can you imagine? It’s like installing a top – level shock – absorption system for the screw pump. The vibration and noise during operation are greatly reduced, and the equipment wear is also significantly decreased. This not only extends the service life, but also creates a quieter working environment for you.

IV. Derived from Rotor Dynamics: Optimizing Stress for Durability

Vigorous carefully optimizes the screw geometric design by leveraging the cutting – edge research results of rotor dynamics, bringing a transformative change to the screw rotor shaft.
The stress is transformed into an approximately symmetric cyclic stress, with the average stress approaching zero, and the absolute value of the stress amplitude is reduced by 30% – 60%. These changes significantly improve the fatigue
