• Q1: What is the key advantage of this electro-hydraulic steering pump compared to a traditional hydraulic pump on a new energy bus?
  A1: The key advantage is significant energy savings and reliable steering assistance even when the engine is off. Traditional pumps run constantly, driven by the engine, wasting energy. Our electric pump operates on-demand, activating and adjusting its output based on actual steering needs. This reduces the load on the vehicle's electrical system, which is crucial for extending the range of new energy buses. Furthermore, it provides reliable power assistance even during engine idle shutdown or reversing maneuvers, enhancing safety.

• Q2: How does the intelligent control feature work to save energy?
  A2: The pump system is connected to a controller that monitors the steering wheel's rotation angle. When the vehicle is moving straight and no steering input is detected, the controller keeps the pump motor at a lower speed, consuming minimal power. The moment you turn the steering wheel, the controller instantly commands the motor to accelerate to a higher speed, delivering full hydraulic power for effortless steering. This "on-demand" operation eliminates constant energy waste.

• Q3: Why is this pump particularly reliable for bus fleet operations?
  A3: Reliability is built into its design. It utilizes a permanent magnet synchronous motor known for its robustness and efficiency. The entire assembly often boasts a high IP67 ingress protection rating, making it resistant to dust and water, which is essential for withstanding harsh undervehicle conditions. Additionally, its design minimizes wear, contributing to a long service life and reduced unscheduled downtime for your fleet.

• Q4: Are there any specific maintenance recommendations for this pump?
  A4: To ensure long-term reliability, we recommend using the specified hydraulic fluid (e.g., ATF Dexron III or equivalent anti-wear hydraulic oil) and regularly checking and replacing the inlet filter. The system is equipped with a self-diagnostic function that can alert operators to potential issues like overheating or voltage abnormalities through warning lights, allowing for proactive maintenance.
