Introduction
The test method of Cavitation Corrosion and Erosion-Corrosion Characteristics Test Equipment is: pump the sample with a standard aluminum automobile water pump, run it for 100h under the conditions of 113 ºC, 103kpa and pump speed of 4600r / min, and then check the water pump to determine the degree of cavitation corrosion, and grade it according to the grading system table.
Characteristic
1. The Cavitation Corrosion and Erosion-Corrosion Characteristics Test Equipment is composed of operation and display, heating control, speed control, pressure control, flow control system and supporting components;
2. Motor: used for coolant circulation drive, linked with water pump;
3. Water pump: the standard ASTM D method requires imported water pump;
4. Vacuum pressure gauge: digital display of real-time pump inlet vacuum;
5. Throttle valve: used to regulate the flow rate of water pump;
6. Heater: heat the coolant to the test temperature;
7. Liquid storage tank: stores cooling liquid for pipeline system;
8. Heat exchanger: provide 35 ~ 38 ºC test temperature through cooling water heat exchange;
9. Regulating valve: three regulating valves are used to adjust vacuum degree and test pressure;
10. Pressure gauge: displays the pressure during the test;
11. Expansion tank: steam expansion device
