How to test hydraulic cylinders? One of the main tasks in hydraulic cylinder manufacturing is also to make sure the cylinders work like they should. This is why careful testing is executed for every cylinder before painting and finally delivering to the customer. The purpose of the testing, also known as proof test, is to ensure the safety and functionality of cylinders. For more information you can get in touch with our hydraulics company in India.
What happens in a proof test?
The basic instructions for a proof test step by step:
- The cylinder is put to the test bench tightly and securely
- Hoses are attached to the cylinder’s oil connections or ports
- Testing pressure is checked from the work order or from the customer’s drawing
- Worker tells the computer the cylinder’s values (the values differ depending on the cylinder in question), the computer starts the test
- During the test, a cylinder makes a specified amount of strokes (as in back and forth motion), this rinses the cylinder from the inside
- After the movements have been carried out, the worker starts the actual proof test, the cylinder is first pushed with overpressure rod out and then rod in
- During the proof test, the welds are inspected in case of any mistakes or leaks in welds or seals
- After the proof test has successfully been carried out, the pressure is released from the cylinder.
When a new product is being tested, a representative from our design department and a supervisor must be present throughout the whole testing sequence. For more information on hydraulics cylinders you can get in touch with our industry experts.
