Hydraulic blasting testing machine
Hydraulic blasting testing machine is a device used to test the bearing capacity of materials or equipment under high pressure. It evaluates whether its performance meets the standards by gradually increasing the water pressure until the test object ruptures or leaks, or whether it can still operate stably under the highest actual working pressure. This type of equipment is commonly used to test the performance of pressure resistant equipment such as pipelines, valves, pressure vessels, hoses, etc.
Mainly used to measure the bearing limit of materials and equipment under high pressure, detect whether structural integrity can be maintained under high pressure conditions, and prevent leakage. Evaluate the compressive strength of pipelines and other equipment in actual usage environments, and confirm their durability and safety under high pressure.
The working principle of the hydraulic blasting test machine is mainly based on gradually increasing the pressure of the testing liquid medium to test the ultimate bearing capacity of the material or equipment until it ruptures or leaks. The following is a detailed explanation of its situation.
1. Liquid transmission pressure
The hydraulic blasting test machine uses water as the pressure medium, which is usually incompressible. Therefore, when the pump injects liquid into a closed testing system, the pressure inside the system will increase with the increase of injected liquid.
2. Sealing and liquid filling
At the beginning of the test, seal the test piece to be tested (such as a pipeline, valve, or pressure vessel) in the testing chamber and fill it with water. The purpose of sealing is to ensure that water does not leak from the system and to concentrate the pressure of the test on the specimen.
3. Pressurization
Use a high-pressure pump to inject water into the system while gradually increasing the internal water pressure. As the water pump continues to operate, the system pressure will increase. The process of increasing water pressure is controllable and can gradually increase to the set pressure range.
4. Pressure monitoring
The pressure sensor in the system will monitor and record changes in pressure in real time. As the pressure gradually increases, the sensor will record this process and generate a pressure curve. These data are helpful for analyzing the performance of materials or equipment.
5. Blasting or leakage
The tolerance limit of the specimen will be tested through the process of continuously increasing water pressure. Ultimately, when the water pressure reaches the material limit of the specimen, the specimen may suddenly rupture, resulting in significant structural damage. Or small cracks may occur on the surface or connection of the test piece, causing water to leak from the system.
6. Recording and analysis
When the specimen ruptures or leaks, the equipment will automatically record the corresponding water pressure value (burst pressure). These data can help determine the pressure resistance performance of materials or equipment and be used for subsequent design optimization or quality evaluation.
7. Safety measures
Due to the high testing pressure, the equipment is equipped with multiple safety measures, such as overpressure protection, automatic pressure relief devices, etc., to avoid accidents caused by excessive pressure.
The hydraulic blasting test machine uses liquid to transmit pressure and tests the pressure limit of materials or equipment through gradually increasing water pressure. Through this method, the maximum pressure that the equipment can withstand in actual use can be effectively evaluated and used for quality inspection and product development.
Attention must be paid to strictly following operating procedures to ensure safety. Before testing, it is necessary to conduct a comprehensive inspection of the equipment and specimens to avoid accidents during the testing process.
