[0004] Therefore, it is urgent to develop a complete set of train tanker sealing test equipment to solve the problem of measuring the sealing of tanker trucks. Utility Model Content

[0005] To solve the above technical problems, the purpose of this utility model is to provide a train tank car seal test device. The control system of this device can control the operation of the entire device, collect the pressure detection value in the device, and issue the command to start and end the test. It controls the start of the test and records the pressure value in the tank car and plots the pressure vs. time curve. The specific technical solution is as follows:

[0014] The utility model has the following beneficial effects:

[0015] This device utilizes a compact booster and valve design, resulting in a small footprint and a measurement accuracy that fully meets the required 0.05% accuracy. The device's design involves a railroad tank car being driven to the test station. A centrifugal pump pumps water from the underground pool to the elevated tank, which is then poured into the tank car. Once the tank car is fully filled, the booster system further increases the water pressure. Due to the large size of the tank, this design allows for faster testing times. The elevated tank ensures that even small pressure measurements can be made, meeting the required pressure. Furthermore, the medium can be circulated directly through the train tank back to the underground pool.
