2. Pipeline systems utilize non-welded connections
3. Control fluid system separation and drive fluid system for ease of observation of test temperature and diverse test medium
4. There are two different control methods available for selection: manual control, computer control
5. Utilizing high-speed sampling cards (U.S. NI) for testing data collection (computer controlled)
6. Software utilizes Force Control configuration software or LABVIEW for programming (computer control) of various auxiliary tools, catering to different installation methods for test pieces.
7. During the test, pressure compensation can be automatically performed; after time failure, pressure drops rapidly, the system automatically stops pressurizing, displays the burst pressure, and generates the final table.
8. Special-designed protective workwear that effectively shields operators and equipment from blast injuries.
9. Computer-controlled function allows for free setting of water filling and exhaust time, pressure maintenance time, water filling cleaning time. Before the test pressure experiment, you can arbitrarily set single or multi-stage pressure maintenance tests. It is possible to set direct burst after pressure maintenance. The pressure rise speed is adjustable and maintained constant. The equipment can be infinitely adjusted. Test data and curve parameters are displayed in real time. After manual termination or burst, the test results can be automatically saved, and test reports can be printed at will. (Computer Control)
Work Flow Description:
Add lubricating oil to the two-body oil atomizer; in the south, use No. 10 or No. 20 mechanical oil, and in the north during winter, use antifreeze mechanical oil or low-foaming hydraulic oil.
2. Fill the storage tank with water or other liquid.
Firstly, close the cutoff valve of the driving air source, connect the air source, and adjust the pressure reducing valve on the two-piece assembly to ensure the driving air pressure ≤ 0.8 MPa.
4. When using water as the pressure testing medium, replace the corresponding fitting according to the thread size of the test hose connector, connect the test hose filled with water, close the stop valve, open the water supply valve, and then open the high-pressure stop valve. Turn on the drive gas switch. The air-liquid booster pump starts, and according to the different boost 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, exhaust the internal gas, 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 "stable pressure increase - timing pressure holding - pressure release" process. The high-pressure cutoff valve is a conical valve pin, 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 close it again. Avoid applying excessive force to damage the valve core and shorten the valve's service life.
Upon completion of the pressure holding time, the buzzer sounds, indicating the end of the test; simply unload. During the test, automatic pressure compensation is available, offering advantages such as stable test pressure and high pressure testing accuracy. In the event of specimen failure, 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 record to a USB drive.
Safety Precautions and Maintenance for Blasting Test Bench:
During hydraulic testing of the container, it is necessary to purge the gas inside the container and connected piping thoroughly. This is particularly important when conducting high and ultra-high pressure endurance tests on the container, as it ensures a smooth and safe pressure increase.
2. During pressure testing, operators must monitor the pressure gauge's rise and check for leaks at the connections. Any issues should be addressed immediately by stopping the pump and releasing pressure.
3. The booster pump solely serves to increase pressure; activating it does not increase displacement. Therefore, when filling the inspected container with liquid, the pump should be deactivated to prevent unnecessary wear on the booster pump's sealing components.
4. The oil atomizer must contain lubricating oil to lubricate the pneumatic pump. The oil amount should be adjusted to 15-20 drops per minute, and refueling in 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 frequently, first using mineral oil and then drying it with low-pressure air.
6. The testing medium for this machine must be kept clean. It is necessary to regularly clean the water tank and filter screen, as a dirty testing medium can lead to poor sealing of the valves on this machine, affecting its operation.
Safety Precautions for Explosive Test Bench Operation:
The core component of this equipment is our independently developed gas-liquid booster pump, which boasts high output pressure, easy adjustment, automatic pressure maintenance, and high cost-performance. Due to these features, it has been widely applied. By adjusting the regulating valve, the input pressure can be controlled, and the output gas can be infinitely adjusted accordingly.
