Frequently Asked Questions
Q:
How does the PM VSD technology contribute to energy savings?
PM VSD (Permanent Magnet Variable Speed Drive) technology matches the pump's output directly to the actual demand, which significantly saves both energy and water compared to conventional fixed-speed pumps.
Q:
What is the benefit of the Deman Cloud Intelligent Control System?
The built-in Cloud function enables 24/7 continuous monitoring and sends out real-time early-warning alerts when there is any data deviation, effectively reducing unexpected downtime losses.
Q:
How does the Three-Stage Vacuum Separation System ensure clean exhaust?
It uses a three-stage process: Stage 1 performs cyclonic separation using centrifugal force; Stage 2 uses impaction separation on the wall surfaces; and Stage 3 utilizes high-efficiency oil-air separator media (multi-layer micro-glass fiber) to remove the finest oil aerosols.
Q:
Why is the Vacuum Pump-Specific Screw Rotor Air-end more efficient?
Featuring a larger rotor diameter and lower rotational speed, its optimized profile and structure achieve a 12% improvement in sealing, a 15% reduction in internal leakage, and a 30% increase in overall efficiency.
Q:
How does the cooling system maintain stability in high temperatures?
The system pairs a high-airflow, low-noise axial fan with an advanced plate-fin heat exchanger. The heat exchanger has separate circuits for oil and air, providing an extra-large dissipation area to protect components in high ambient temperatures.
Q:
What role does the VSD-Specific Vacuum Intake Valve play?
It coordinates with the PM VSD drive to manage airflow during startup for rapid vacuum attainment, and prevents air backflow during shutdown to protect the vacuum pipeline system.
