Frequently asked questions
What is the difference between a hydraulic pump and a motor?
A pump converts mechanical energy into hydraulic energy. A motor converts hydraulic energy into mechanical rotation. They use similar internal components but are engineered for opposite power flows.
How do I choose the right hydraulic cylinder?
Consider the required force, stroke length, mounting position, and speed. Check the bore size and rod diameter against your load. Verify the seal type matches the operating temperature and fluid.
What is the role of hydraulic fluid filtration?
Filters remove particulates that cause wear in pumps, valves, and cylinders. Regular filtration extends component life and prevents system failure from contamination.
What should I check before buying a hydraulic valve?
Verify the flow rate, pressure rating, port size, and control type. Match the valve to your system's pressure profile and ensure it is compatible with your manifold design.
How do I troubleshoot a slow hydraulic cylinder?
Check for fluid leaks, air in the system, or a restricted filter. Verify the pump output and cylinder seal integrity. Measure system pressure to identify the bottleneck.
What standards should I follow for hydraulic system safety?
Follow applicable national and international standards for pressure vessels, piping, and electrical safety. Ensure all components are rated for the system's maximum pressure and temperature.
