However, this method has the following drawbacks: 1. because the water tank has more welding lines, the environment in a laboratory is moist, the water tank shell is in a moist state, if a test water tank has a fine water leakage point, a tester cannot accurately judge whether water drops outside the water tank belong to the fine defect of the welding line of the water tank or water leakage caused by a sealing element, and the result is misjudged or misjudged. 2. After the water tank is filled with water, the weight of the water tank body and the internal water can reach 42kg, inspection personnel cannot turn over the water tank for inspection, and the accessibility of the inspection is poor. 3. The test pressure is controlled by a pointer type pressure gauge and a valve, slight pressure change can not accurately determine the pressure of the water tank by the pointer type pressure gauge, and the change of a pointer of the pressure gauge can only be observed by increasing detection time. 4. The test time is too long, and each test can only carry out the leakproofness test to single water tank, can't improve production efficiency. 5. The test water capacity of each water tank is about 28-35 liters, the test water consumption is large, and the water resource waste is huge. 6. The pressure is controlled by starting and stopping the water inlet amount of the manual valve, and the safety is poor.
