AC series hydraulic power unit Suppliers

1. What is the core working principle of the AC hydraulic power unit?
The unit converts electrical energy into hydraulic energy by driving the hydraulic pump through an AC motor. The motor output shaft drives the positive displacement pump (such as a gear pump, vane pump or plunger pump) to rotate and generate high-pressure oil. After the oil is adjusted by the control valve group for flow and pressure, it drives the actuator (cylinder or motor) to complete linear or rotational movement. The system pressure is set by the overflow valve and maintained stable by the accumulator or pressure sensor. Ningbo Panic focuses on optimizing energy conversion efficiency in its design to ensure the accuracy and response speed of power output.

2. What are the main advantages of the AC hydraulic power unit compared to other drive methods?
The popularity of AC power supply makes it easy to install and has low operation and maintenance costs; the three-phase asynchronous motor has a simple structure and strong overload capacity, which ensures the reliability of the system under heavy load conditions; the start-stop control is flexible, and stepless speed regulation can be achieved with frequency conversion technology; the noise and vibration control is better than that of internal combustion engine drive, suitable for indoor or precision environments. Ningbo Panic aims to meet the needs of the high-end market by reducing operating noise through precision manufacturing and strengthening thermal management design to extend continuous working time.

3. What are the key performance indicators of such units?
The core indicators include: rated pressure (such as 21MPa/35MPa level), flow range (need to match the actuator speed requirements), motor power (determines the output torque capacity), oil tank capacity (affects heat dissipation and oil cleanliness), and control mode (manual/electromagnetic/proportional valve control). Ningbo Panic's products have been verified by international standards such as ISO 4413. Its units exported to the European, American and Japanese markets have particularly strengthened EMC anti-interference design and IP protection level to adapt to harsh industrial environments.

4. How to ensure system reliability and life?
First, use low-pulsation pumps and shock-absorbing joints to reduce hydraulic shock; second, configure multiple filtration systems (suction/pressure/return oil filtration) to control the oil NAS level; in addition, the coordination of temperature sensors and air cooling/water cooling devices can prevent overheating. Ningbo Panic implements full-process quality testing from design to delivery, including 72-hour full-load fatigue testing, pressure pulsation spectrum analysis, and accelerated aging verification of seals to ensure that the performance degradation during the product life cycle meets the standards of high-end customers.

5. What is the direction of technological evolution under the trend of energy saving and intelligence?

Current development focuses on: variable frequency control (dynamically adjusting the motor speed according to load demand to reduce no-load energy consumption), integrated electro-hydraulic modules (embedding pumps, valves, and sensors into compact units), and Internet of Things interfaces (real-time monitoring of oil temperature, contamination, pressure curves, and early warning of faults). Ningbo Panic's R&D system has been integrated into these trends. Its new generation of units supports Modbus/PROFINET communication protocols, providing interactive hydraulic power solutions for smart factories.

6. How does Ningbo Panic's professional practice enhance product value?
The company is oriented towards the high-end market, and its core strategies are reflected in: application of material science (boron alloy cylinder and silicon carbide sealing ring are used to enhance wear resistance), topology optimization design (reducing flow channel pressure loss through CAE simulation), and global supply chain management (key components such as bearings envelop SKF/Schaeffler system). Export products strictly implement CE/PED/UL certification, and the whole chain quality control from casting blank to finished product assembly enables its units to achieve near zero failure rate operation in scenarios such as ship deck machinery and precision injection molding machines.
