Проверката на стегнатостта на резервоара за мобилно гориво е от решаващо значение за ефективно предотвратяване на изтичането на гориво и избягване на опасностите за безопасността . Ето някои често срещани методи за проверка:
1. Проверка на външния вид
First, conduct a comprehensive appearance inspection of the fuel tank to check whether there are obvious oil stains, oil marks or signs of fuel leakage on the surface of the fuel tank. Pay special attention to welds, joints, around valves, and corners of the fuel tank, which are prone to cracks or poor sealing. If fuel leakage is found, it means that there is a problem with the sealing and further inspection and repair са необходими .
2. тест за налягане
This is a more accurate inspection method. You can use special pressure testing equipment to seal the fuel tank and fill it with a certain pressure of gas (usually air). The general pressure value depends on the specifications and requirements of the fuel tank, usually between 0.1-0.3MPa. After filling the gas, observe the reading of the pressure gauge. Within the specified time (such as 10-15 minutes), if the pressure drops by more than a certain range (such as 0.05MPa), it means that there is a leak in the fuel tank and the leak point needs to be found and repaired. In order to locate the leak more accurately, soapy water can be applied to the part where the leak may occur. If Генерират се мехурчета, частта може да бъде определена като точка на изтичане.
3. Метод за наблюдение на нивото на горивото
Add a certain amount of fuel to the fuel tank and observe the changes in the fuel level over a period of time. If the level drops significantly without using fuel, there may be a leak in the fuel tank. However, this method is relatively inaccurate because the drop in the level may be affected by other factors, such as the volatilization of fuel, but it can be used as a preliminary inspection method.
4. тест за вакуум
Test the fuel tank using a vacuum test device. Pump the inside of the fuel tank into a vacuum state, and then observe the maintenance of the vacuum degree. If the vacuum℃cannot remain stable and there is a significant rebound phenomenon, it means that air has entered the fuel tank, that is, there is a sealing problem. This method is more effective for detecting tiny Течове .
