[0027] like Figure 4 and Figure 5 As shown, the rapid pump drainage device 03 includes a water tank 31, a steel wire reinforced hose 32, an impeller pump 33, and a motor 34. The water tank 31 is installed on the top of multiple supports 12. The steel wire reinforced hose 32 is connected and installed at the front end of the water tank 31. The impeller pump 33 is connected and installed on the steel wire reinforced hose 32.

Then, lift the flange 55 using a magnetic lifter or other auxiliary equipment, and then fix the flange 55 to the container with bolts. Handle 206 is convenient for workers to grip. Operate pipe joint 354 to improve the ease of connecting the flange 55 to the container. Then, turn on motor 1 34 and motor 2 43. Motor 1 34 provides power to drive impeller pump 1 33 to pump water from water tank 31 through steel wire reinforced hose 32. Motor 2 43 provides power to drive impeller pump 2 42 to pump water from water tank 31 through hose 41. The pumped water flows into the container through tee joint 51. When the water in the container... When the container is nearly full, close the electrically controlled valves in the flow channel of motor 34 and tee connector 51 to prevent impeller pump 33 from being damaged by backflow of water during pressurization. Then, keep motor 43 open and check valve 44 to prevent backflow of water inside hose 41 during drainage, reducing the pressure on impeller pump 42 and thus increasing the maximum water pressure that impeller pump 42 can output, thereby achieving the pressurization test of the container. After the test, slowly open the electrically controlled valve in the flow channel of tee connector 51 and reverse motor 34 to drain the water in the container back into the water tank 31. Then, flange 55 can be removed to perform pressurization tests on the remaining containers.

[0035] like Figures 1 to 7 As shown, this utility model discloses a pressure vessel strength testing device. During operation, the machine is first pushed close to the container to be tested. Then, a magnetic lifter or other auxiliary equipment is used to lift the flange 55, which is then bolted to the container. Handle 206 facilitates worker gripping and operation of pipe joint 354, improving the ease of connecting the flange 55 to the container. Next, motors 1 (34) and 2 (43) are turned on. Motor 1 (34) provides power to drive impeller pump 1 (33) to extract water from water tank 31 through steel wire reinforced hose 32. Motor 2 (43) provides power to drive impeller pump 2 (42) to extract water from water tank 31 through hose 41. All extracted water is connected through a tee. The water flows into the container from head 51. When the container is almost full, close the electrically controlled valves in the flow channel of motor 34 and tee connector 51 to prevent impeller pump 33 from being damaged by backflow of water in the container during pressurization. Then, keep motor 43 open and check valve 44 to prevent backflow of water inside hose 41 during drainage, reducing the pressure on impeller pump 42 and thus increasing the maximum water pressure that impeller pump 42 can output, thereby achieving the pressurization test of the container. After the test, by slowly opening the electrically controlled valve in the flow channel of tee connector 51 and reversing motor 34, the water in the container can be drained back into the water tank 31. Then, flange 55 can be removed to perform pressurization tests on the remaining containers.

Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0037] The main functions achieved by this utility model are: by setting up a pressurizing pump water device 04 to pressurize and supply water to the container, the test pressure is increased without changing the pump specifications, thereby improving the applicability of the machine; and by setting up a moving device 02 to facilitate the movement and use of the machine, the ease of use of the machine is improved; this solves the existing technical problems that the pressure that the existing test device can provide is almost entirely provided by the water pump itself, resulting in low test pressure, poor machine applicability, and the existing test device cannot be moved and is also difficult to use.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
