Problems solved by technology

[0003] 1. Use clean water for the test, corrosion will occur in the pump cavity
[0004] 2. Use the cutting fluid for the test, the phenomenon of rust in the pump cavity will be reduced, but the cutting fluid will turn black and smelly after being used many times, and the treatment of the cutting fluid requires a professional company, which increases the cost
[0005] 3. There are many operating procedures and a waste of working hours

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.

Description

technical field [0001] The invention relates to a pressure test device for pumps. Background technique [0002] After the pump assembly is completed, each pump must be subjected to a pressure test to verify the pressure resistance of the parts and the quality of the assembly. At present, the hydraulic test is used, that is, the pump cavity is filled with water, the water inlet and outlet of the pump are closed with a blind flange, and a booster pump is used. Gradually increase the pressure of the pump chamber to the specified value, maintain the pressure for the specified time, and finally remove the blind flange of the pump inlet and outlet, and dump the water. But it has the following defects: [0003] 1. Use clean water for the test, corrosion will occur in the pump cavity. [0004] 2. Use the cutting fluid for the test, the phenomenon of rust in the pump cavity will be reduced, but the cutting fluid will turn black and smelly after being used many times, and the treatm...
