The invention provides a device for testing negative pressure shock resistance and pulse pressure resistance of a water heater. The device comprises a water supply tank, a negative pressure shock resistance test pipeline and a pulse pressure resistance test pipeline. The negative pressure shock resistance test pipeline and the pulse pressure resistance test pipeline are both connected with the water supply tank, a water supplement port and an overflow port are formed at the upper part of the water supply tank, a water outlet is formed in the bottom of the water supply tank, a water outlet valve is connected to the water outlet, and a return water port is formed between the water supplement port and the water outlet. A water ring vacuum pump, an intake electric three-way ball valve, an inflation electric three-way ball valve and a negative pressure sensor are arranged on the negative pressure shock resistance test pipeline. The pulse pressure resistance test pipeline mainly comprises a booster pump, a booster electric three-way ball valve, a broken sample collection device and a positive pressure sensor. During operation, the other ends of the negative pressure shock resistance test pipeline and the pulse pressure resistance test pipeline are connected with the water tank of the water heater required for test, and all electric elements are connected with a programmable controller (PLC). The device has a simple structure, works reliably and improves the test accuracy and the control accuracy.
Description
technical field [0001] The invention relates to a device for carrying out a negative pressure impact and pulse pressure test on a water heater, and belongs to the technical field of pressure vessels, especially the mechanical performance detection of water heaters. Background technique [0002] The water heater is a pressure vessel, which needs to be subjected to negative pressure shock and pulse pressure tests. The test requirements are in accordance with the national standard GB / T 19141-2011 "Technical Conditions for Household Solar Water Heating Systems" in "7 Technical Requirements". Pressure Shock", "7.18 Pulse Pressure" and "8.17 Negative Pressure Shock Resistance Test" and "8.18 Pulse Pressure Test" of "8 Test Methods" ""6.7 Vessel Pulse Pressure" of "6 Performance Requirements" and "7.10 Vessel Pulse Pressure Test Method" of "7 Test Methods"). According to the standard, the water heater needs to be subjected to a high pressure 0.6mpa, a low pressure (15% of the high...
