FAQ
Q1Is this hydraulic motor specifically designed for deep well applications? Can it reliably operate at 50-meter depths?
Yes, you've found the right product. The design and material selection of this vane motor are tailored for the demanding conditions of deep well applications. Its key features, such as corrosion-resistant coatings and specialized shaft seal designs, enable it to operate reliably long-term at 50-meter water depths and under similar pressures. We understand the high cost of deep well maintenance, so reliability is our primary design objective.
Q2For deep well use, how is the motor's sealing performance? How do you prevent water ingress causing failure?
Sealing performance is the lifeline of a deep well hydraulic motor. We employ a multi-stage sealing system to ensure absolute reliability:
- Shaft Seal: Utilizes mechanical seals or high-performance lip seals specifically designed for long-term, high-pressure submersion, effectively blocking external water pressure.
- Housing & Connection Protection: The overall structural design and O-rings ensure housing integrity, preventing leaks even under high water pressure.
Q3What should I pay attention to during the installation and maintenance of this deep well motor? Do you provide technical support?
Correct installation is crucial. We provide detailed installation guidelines, emphasizing:
- Cleanliness: Ensure extreme cleanliness when connecting hydraulic lines to prevent contaminants from entering the motor.
- Alignment and Handling: Use appropriate tools to avoid damage to the shaft extension and connection threads.
Q4What are the main performance advantages of the Eaton Vickers hydraulic vane motor?
The motor features a wide speed range, low noise output, and the capability for both forward and reverse rotation with sensitive action response. Thanks to its radial hydraulic balance design, it achieves high working pressure and a long service life while maintaining a small, lightweight, and simple structure that is easy to service.
Q5What are the limits and conditions for intermittent work operation?
Intermittent work is defined as occupying no more than 10% of the total working time. Under intermittent conditions, each period of operation at maximum pressure and/or speed must not exceed 6 seconds to prevent damage and ensure motor longevity.
Q6How do the 114 and 124 models differ in rotation and pressure specifications?
The 114 model is rated for 2500 psi under Counter-Clockwise (CCW) rotation and 2250 psi under Clockwise (CW) rotation as viewed from the shaft end. The 124 model is designed specifically for one-way rotation at 2500 psi.
