Three Roller Hydraulic Plate Rolling Machine

We are a professional manufacturer of Three roller hydraulic plate rolling machine with over 10 years of industry experience. Today, we would like to introduce to you:

As an important mechanical equipment, Three roller hydraulic plate rolling machine plays a crucial role in industrial production. In order to ensure its stable and reliable performance, a series of performance testing standards have been developed. It uses external forces such as hydraulic pressure and mechanical force to move the work roll, thereby bending or coiling the sheet metal into shape. Based on the rotational motion and position changes of the work roll of different shapes, elliptical parts, arc-shaped parts, cylindrical parts and other parts can be processed. The relevant standards for performance testing of this product are as follows.

1. Sealing test
Sealing is an important indicator in the performance testing of hydraulic plate rolling machines, which involves the sealing performance of various components in the hydraulic system to ensure that no leakage occurs during operation. The sealing test usually includes two aspects: room temperature sealing and low-temperature sealing. Room temperature sealing is evaluated for leakage through empirical calculation formulas, while low-temperature sealing requires injecting antifreeze into the liquid cooling assembly and testing it in a low-temperature environment to ensure good sealing performance even under abnormal conditions.
2. Static pressure strength test
Static pressure strength testing is used to evaluate the durability of hydraulic bending machines under static pressure. During the testing process, the liquid cooling assembly is filled with water or compressed air at a certain pressure and maintained for a period of time to observe whether there is any significant deformation of the parts. This test can reflect its stability under long-term static load.
3. High temperature resistance test
The high temperature resistance test is conducted to verify the performance of the product in high temperature environments. During testing, a specific ratio of ethylene glycol and water mixture is introduced into the liquid cooling system, and a certain pressure is applied to conduct a long-term high-temperature resistance test in a high-temperature environment. After the experiment, it is necessary to conduct testing according to the standards of sealing testing to ensure that good sealing performance can still be maintained under high temperature conditions.
4. Pressure cycle performance testing
The pressure cycling performance testing simulates its pressure changes in actual operation. The test needs to be conducted on a dedicated testing device, observing the response and stability of the hydraulic system by applying different pressure cycles. This test is crucial for evaluating the performance of hydraulic bending machines under dynamic working conditions.
5. Vibration testing
Vibration testing is used to evaluate the stability and reliability of hydraulic plate bending machines under vibration. During the testing, the liquid cooling system is filled with room temperature water and sealed, and fixed on a vibration test bench for vibration performance testing. This test can reveal the performance of hydraulic bending machines in vibration environments that may be encountered during transportation, installation, or use.
6. Internal corrosion test
The internal corrosion test is conducted to ensure that its performance will not be affected by internal corrosion during long-term use. Experiments are usually run for a certain period of time under specific temperature and flow conditions, and the pH value and appearance of the solution are regularly checked. This test is very important for ensuring the service life and reliability of the product.
7. Blasting performance test
Blasting performance test is a test conducted under abnormal conditions to evaluate the safety of hydraulic plate rolling machines when exceeding the design pressure. The experiment is conducted on a blasting testing machine, gradually increasing the pressure until the system fails, and recording the failure pressure and location. This test can ensure that there will be no explosion in case of accidents, ensuring the safety of operators and equipment.
8. Pressure drop test
The pressure drop test is used to evaluate the flow resistance of a hydraulic plate rolling machine under given flow conditions. By introducing coolant at a given temperature into a liquid cooling system and recording the flow resistance, the flow performance of the hydraulic system can be understood. This test is of great significance for optimizing the design of hydraulic systems and improving work efficiency.
9. Cleanliness test

The cleanliness test is to ensure that there are no residual impurities inside the product, which may have a negative impact on the performance of the hydraulic system. Testing usually involves injecting antifreeze into the tested product cavity, conducting vibration testing, flushing with clean gas, and filtering to test the quality and solid particle size of residual impurities in the cold plate cavity. This test is crucial for ensuring the stability and reliability of the hydraulic system.

In summary, the performance testing standards for Three roller hydraulic plate rolling machine cover multiple aspects such as sealing, static pressure strength, high temperature resistance, pressure cycling, vibration, internal corrosion, blasting performance, pressure drop, and cleanliness. These testing standards aim to ensure that the hydraulic bending machine can maintain stable performance and reliability under various working conditions, thereby ensuring production safety and improving work efficiency.
