the second step is that: because the specifications and directions of the impeller cavity cover products (44) are different, when the photoelectric sensor (46) senses that the impeller cavity cover products (44) are in place, the rotating motor (51) is adopted to drive the side edge of the impeller cavity cover product (44) on the motor cavity cover tool (45) to correspond to the inflating mechanism (4), the position is determined through the sensor (52), the sliding table cylinder (22) on the inflating rack (14) drives the plugging pipe (20) to be in plug-in press-connection with the impeller cavity cover products (44), and then the inflating driving motor (16) adjusts the angles of the air inlet pipe (21) and the impeller cavity cover products (44) through the synchronous belt pulley (17);
the third step: the exhaust mechanism (3) pushes the exhaust connection lifting plate (29) connected with the floating joint (28) through the exhaust lifting cylinder (24), and the exhaust connection lifting plate (29) lowers the plugging connector (30) and the pressure head (31) to be inserted and pressed with the impeller cavity cover product (44);
the fourth step: a probe seat (48) on a rotary supporting plate (54) adopts a probe lifting cylinder (49) to communicate a probe (47) with a motor cavity cover tool (45) in a circuit mode, when the rotating speed of an impeller cavity cover product (44) reaches 4000 revolutions per minute, a pressure switch (12) in an airtight control mechanism (1) is opened, a gas source input device (13) enables gas to pass through a pressure regulating valve (11), an electric proportional valve (10), a restrictor (8) and enter a gas inlet pipe (21), and the gas pressure at a plugging connector (30) is digitally displayed by a pressure sensor (23).
10. The operation method of the electronic water pump EOL test apparatus of claim 9, wherein: when the transverse moving cylinder (58) on the transplanting machine frame (56) moves the air claw (59) to the lifting tray frame (6), the lifting cylinder (57) drives the clamping jaw (60) to descend, and simultaneously the air claw (59) opens the clamping jaw (60), and the jacking cylinder (42) on the jacking tray frame (6) jacks up to enable the floating jacking shaft (41) to move upwards, the push plate (37) lifts the tray (35) to eject the impeller cavity cover product (44) on the tray carrier plate (33), then the air claw (59) closes the clamping jaw (60) to clamp the impeller cavity cover product (44), then the lifting cylinder (57) drives the clamping jaw (60) to ascend, the transverse moving cylinder (58) clamps the impeller cavity cover product (44) above the rotating platform (7), the lifting cylinder (57) drives the clamping jaw (60) to descend, and opening the clamping jaw (60) through the air claw (59) to place the impeller cavity cover product (44) on the motor cavity cover tool (45).
