Features:

The main components are sourced from our company's self-produced and matched products.

2. The pipeline system utilizes non-welded connections

3. Control fluid system and facilitate the separation of the driven fluid system, making it easy to observe test temperatures and diversify testing media.

4. Two different control methods are available for selection: manual control, computer control

5. Utilizing high-speed sampling cards (U.S. NI) for testing data collection (computer-controlled)

6. Software is programmed using Force Control configuration software or LABVIEW (computer control) for a variety of matching tools, catering to different installation methods for test pieces.

7. During the testing process, automatic pressure compensation can be performed; after time failure, pressure drops rapidly, the system automatically stops increasing pressure, displays the burst pressure, and generates the final table.

8. Custom-designed protective gear, effectively safeguarding against injuries to operators and equipment from explosions.

9. Computer-controlled functionality allows for flexible setting of filling and exhaust time, pressure holding time, filling cleaning time. Before the test pressure experiment, you can arbitrarily set single or multi-stage pressure holding tests. Pressure holding can be followed by direct bursting, with adjustable and constant pressure rise speed. The equipment can be infinitely adjusted. Test data and curve parameters are displayed in real-time. After manual termination or bursting, test results can be automatically saved, and test reports can be printed at will. (Computer Control)

Process Description:

Add lubricating oil to the oil atomizer of the two-body unit. In the south, use No. 10 or No. 20 mechanical oil; in the north during winter, use antifreeze mechanical oil or low-viscosity hydraulic oil.

2. Fill the storage tank with water or other liquids.

Firstly, close the drive gas source shut-off valve, connect the gas source, and adjust the pressure reducing valve on the two-in-one assembly to ensure the drive pressure is ≤0.8 MPa.

4. When using water as the pressure testing medium, replace the corresponding connector according to the thread size of the test hose fitting, connect the test hose filled with water, close the stop valve, open the water supply valve, and open the high-pressure stop valve. Open the drive gas switch. The gas-liquid booster pump starts up, and according to the different pressure ratios of the pumps, when the gas source pressure is set to 0.7 MPa:

Output Liquid Pressure = Drive Gas Pressure * 7

After the test piece is installed, evacuate the internal gas of the test piece, turn on the power switch, manually rotate the drive gas pressure regulating valve to adjust the pressure between 0.4-0.8 Mpa, manually set the output pressure and pressure-holding time, then press the work switch on the operation panel. The equipment will automatically complete the test according to the process of "stable pressure increase - timing pressure holding - pressure release." The high-pressure cutoff valve is a conical valve needle, and the closing force must not exceed 18N/m. If there is a leak in the cutoff valve during the pressure increase process, the correct operation is to release the pressure and then re-close it. Avoid applying excessive force to damage the valve core and shorten the valve's service life.

Upon completion of the hold time, the buzzer sounds, indicating the test is finished, and unloading can be performed. During the test, automatic pressure compensation can be applied, offering advantages such as stable test pressure and high pressure test accuracy. In case of specimen failure, the pressure drops rapidly, preventing continuous high-pressure liquid ejection, thus maximizing safety for personnel and machinery. After the highest pressure on the equipment's pressure gauge is reached and the timer ends, simply copy the pressure curve records to a USB drive.

Safety Precautions and Maintenance for Blasting Test Bench

When conducting hydraulic tests on containers, it is essential to remove the gas inside the container and connecting pipes, especially when performing high and ultra-high pressure strength tests on the container. This ensures a smooth and safe increase in pressure.

During pressure testing, operators must monitor the pressure gauge's rise and check for any leaks at the connections. If any issues are detected, the pump should be immediately stopped and the pressure released to eliminate the problem.

3. The booster pump solely serves to increase pressure; starting the pump does not increase displacement. Therefore, when filling the inspected container with liquid, the pump should be stopped to prevent unnecessary wear on the booster pump's seals.

4. The oil atomizer must contain lubricating oil to lubricate the pneumatic pump. The oil volume should be adjusted to 15-20 drops per minute, and refueling the oil cup must be done when there is no pressure.

5. Regularly drain the accumulated water in the separator filter. Clean the filter cup water frequently, first using mineral oil to clean and then drying the cup with low-pressure air.

6. The testing medium of this machine must be kept clean. It is necessary to regularly clean the water tank and filter mesh, as a dirty testing medium will lead to inadequate sealing of the valves on this machine, affecting its operation.

Safety Precautions for Explosive Test Bench Operation:

This equipment features a core component, our independently developed gas-liquid booster pump, which boasts high output pressure, easy adjustment, automatic pressure maintenance, and high cost-performance. Due to these numerous advantages, it has been widely applied. By adjusting the regulating valve, the input pressure can be controlled, allowing the output gas to be infinitely adjusted.
