What procedures are required for inspecting a gas cylinder?

[StAnnie]

Inspecting a gas cylinder requires the gas cylinder usage registration certificate from the oil-to-gas conversion, the gas cylinder factory qualification certificate, the gas cylinder installation supervision inspection certificate, the vehicle's driving license, and the owner's ID card. Below is relevant information about the gas cylinder: 1. Function of the gas cylinder: When the rotor and lubricating oil rotate, suction is generated to draw out the internal pressure air produced during braking in the booster, which then returns to the oil reservoir along with the lubricating oil through the oil return line. The lubricating oil settles, and the air is discharged through the exhaust hole on the upper cover, improving the safety performance of the braking system. 2. Materials required for the annual inspection of the gas cylinder: For the gas cylinder inspection, the following materials need to be prepared: one copy of the "Motor Vehicle Registration Certificate," one copy of the "Vehicle Driving License," one copy of the "Gas Cylinder Usage Registration Certificate," and the "Gas Cylinder Qualification Certificate."
