FAQ
Q1: Is this hydraulic motor specifically designed for deep well applications? Can it reliably operate at 50-meter depths?
A: 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.
Q2: For deep well use, how is the motor's sealing performance? How do you prevent water ingress causing failure?
A: 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.
Q3: What should I pay attention to during the installation and maintenance of this deep well motor? Do you provide technical support?
A: 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.
Q4: What series and displacement options are available for these hydraulic vane motors?
A: The motor is available in standard series 25M, 35M, 45M, and 50M, as well as heavy-duty bearing options 26M, 36M, 46M, and 51M. Displacements range from 43.9 ml/r (2.68 in³/r) for the 25M series up to 317.1 ml/r (19.35 in³/r) for the 50M series.
Q5: What are the maximum speed and pressure capabilities of the 35M and 50M series?
A: The 35M series has a maximum speed of 4000 r/min at 34 bar (500 psi) and can operate up to 3000 r/min at 172 bar (2500 psi). The 50M series can run up to 3200 r/min at 34 bar (500 psi) and up to 2400 r/min at 172 bar (2500 psi).
Q6: What mounting and shaft configurations are provided in the model designation?
A: These motors feature an SAE 2-bolt mounting flange and SAE 4-bolt flange connections. Shaft options include a Straight Key Shaft (Type 1) and a Spline Shaft (Type 11). Multiple cover end positions are available, including opposite the shaft end oil port (A), 90° CCW (B), inline (C), and 90° CW (D).
