Abstract
The invention discloses a pressure test device of a pump. The pressure test device of the pump comprises a main air pipe. One end of the main air pipe is an air inlet end, and the other end of the main air pipe is an air outlet end. The position, between the air inlet end and the air outlet end, of the main air pipe is connected with a hose through a hose connecting port, an air outlet of the hose is connected to a pump cavity of the pump to be tested, the air inlet end of the main air pipe is connected with an air source, a pressure regulating valve, a first opening/closing valve, a pressure gage and an electric contact pressure gage are sequentially arranged between the air inlet end of the main air pipe and the hose connecting port, and the electric contact pressure gage is connected with an alarm and controls the minimal pressure of air pressure. When the pump cavity leaks air and the leakage rate exceeds a specified value, the alarm connected with the electric contact pressure gage gives an alarm. The pressure test device of the pump can avoid corrosion inside the pump cavity when utilizing compressed air to carry out tests, and is convenient and rapid to operate in tests.
