Requirements for external control handles on axial piston pumps may vary depending on specific design, application and industry standards. However, there are some general considerations and requirements to ensure safe and efficient operation. Here are a few key aspects to keep in mind: 1. Ergonomics and accessibility: External control handles should be designed with ergonomic principles in mind to provide comfortable and intuitive operation. They should be easily accessible and positioned so that the operator maintains the correct posture when operating the pump. The shape, size and grip of the handle should be designed to facilitate smooth and precise control. 2. Control range and sensitivity: The control handle should provide sufficient control range to allow precise adjustment of pump parameters such as displacement or flow. The handle should also provide the appropriate sensitivity to make fine adjustments, ensuring the operator has precise control over the pump's performance. 3. Durability and resistance: External control handles shall be constructed of durable materials capable of withstanding the requirements of the operating environment. They should be resistant to corrosion, impact and wear. Additionally, handles should be designed to maintain their functionality and integrity even when subjected to vibration, temperature changes, or exposure to harsh chemicals.
