FAQs about GY Hydraulic
Selection and Customization
1. How do I choose the right hydraulic cylinder?
You should consider the working pressure, load, stroke, installation space, operating speed, duty cycle, and working environment. Selecting a cylinder based only on bore size or price may result in insufficient force, unstable operation, seal failure, or a shorter service life.
2. Which hydraulic cylinder specifications can you customize?
We can customize the bore diameter, rod diameter, stroke, mounting style, working pressure, port type, sealing system, cushioning structure, sensor interface, and surface treatment. You can also provide drawings, samples, or equipment parameters for custom production.
3. Can you manufacture a custom hydraulic cylinder without a complete drawing?
Yes. You can provide the application, load, working pressure, mounting dimensions, required stroke, operating speed, and working environment. Our engineering team can help determine the cylinder structure and key technical specifications.
4. How do I calculate the required hydraulic cylinder force?
Hydraulic cylinder force mainly depends on the working pressure and the effective piston area. Actual selection should also consider pressure loss, friction, load variation, and an appropriate safety factor.
Quality, Performance, and Service Life
1. How do you ensure hydraulic cylinder quality?
Quality control covers material selection, machining accuracy, welding quality, seal compatibility, and assembly procedures. Finished cylinders are inspected through dimensional checks, pressure testing, leakage testing, and functional testing.
2. Why does a hydraulic cylinder leak oil?
Common causes include worn seals, a scratched piston rod, incorrect assembly, contaminated hydraulic oil, excessive side loading, or system pressure exceeding the cylinder’s design limit.
3. How can I extend the service life of a hydraulic cylinder?
Avoid overpressure, side loading, and external impact on the piston rod. Keep the hydraulic oil clean, replace worn seals when necessary, and ensure the cylinder is correctly aligned with the equipment’s direction of movement.
4. What applications are welded hydraulic cylinders suitable for?
Welded hydraulic cylinders have a compact structure and flexible mounting options. They are commonly used in construction machinery, agricultural equipment, material-handling systems, vehicles, industrial machinery, and space-limited applications.
Ordering, Lead Time, and After-Sales Support
1. What information is required for a hydraulic cylinder quotation?
Please provide the cylinder type, bore diameter, rod diameter, stroke, working pressure, mounting style, port specifications, order quantity, and application. Complete information allows us to prepare a more accurate quotation and technical proposal.
2. Do you support prototype and small-batch orders?
Yes. For custom hydraulic cylinder projects, we can produce prototypes for dimensional, installation, and performance verification before moving to batch production.
3. What is the lead time for custom hydraulic cylinders?
Lead time depends on the cylinder structure, materials, order quantity, machining requirements, and testing standards. Special seals, sensors, surface treatments, or complex mounting designs may require additional production time.
4. What should I do if I experience an installation or operating problem?
Please provide the product model, order information, installation photos, system pressure, and a description of the problem. Our technical team will determine whether the issue is related to cylinder selection, installation, system parameters, or product components.
