I. Application scope of the blasting test machine：
According to the customer's requirements, a special testing machine is provided to meet the 5MPa static pressure, 10MPa burst test, and the maximum 1.2MPa pressure cyclic water hammer test for the water purifier. It is used to check whether the components of smart toilets, water purifiers, water supply systems and other products meet the design requirements. The parameters are set by microcomputer control, and the test is completed by the automatic control of the microprocessor. The parameters are set through the touch screen, and the test is completed by the PLC automatic control. Reports can be generated and printed. The professional testing software displays functions such as real-time pressure value, test time and test status during the test process. The equipment has functions such as overload protection; the equipment calibration function is simple and convenient, and it is achieved through precision... 
The pressure instrument can be calibrated by simply inputting the software parameters.

III. Operating Instruction Manual for Blasting Test Machine： 
1. Pressure resistance and burst test: The static hydraulic, burst test system consists of an air-driven booster pump, an air control solenoid valve, pressure sensors, and other pressure components. First, the air source is turned on and the air pressure is adjusted through an air filter and pressure reducing valve to provide air to the air-driven liquid booster pump. The air-driven liquid booster pump starts to provide pressure to the system. When the sample reaches the required pressure, the sensor transmits the signal to the PLC control system, which then sends a signal to close the air control solenoid valve and cut off the air source. At this point, the air-driven liquid booster pump stops working, and the sample enters the pressure resistance holding stage. When the sample ruptures, the solenoid valve closes and cuts off the air source, and the air-driven liquid booster pump stops working. At this time, the controller records the instantaneous burst pressure value and displays it on the computer. 
2. Water hammer test: The water hammer test system is composed of a high-flow electric pump, an overflow valve, a switching valve, and pressure components such as sensors. The two overflow valves provide the upper limit pressure. When the switching valve is opened, the system obtains the lower limit pressure. The continuous opening and closing of the switching valve results in the pressure variation required for the test, which is the pressure cyclic water hammer test. The pressure sensor collects the pressure signal and transmits it to the processor. After the processor collects the data, it performs data processing and realizes the pressure curve waveform through the microcomputer. 
3. Test Procedure Description: First, fill the tested pipe joint with water. Then, connect the shut-off pipeline, adjust the test pressure, and proceed with the test on the computer. 
Set the parameters, including pressure, cycle, and frequency, etc. Start the test pump to pump water from the medium tank into the pipeline. The program will automatically perform the pressure circulation.
