1. Airtightness: Whether the entire oil and gas recovery system is leaking. This system includes: gas return copper pipe of oil dispenser, buried oil and gas recovery pipeline, liquid collection tank, oil tank, and ground vent pipe. If there is a leak in one place, it will fail.

Note: The copper three-way valves in all dispensers must be opened during testing.

2. Liquid resistance: It is to check whether the oil and gas runs smoothly in the pipeline.

Note: When testing, you need to open the oil and gas recovery port, which is next to the oil discharge port.

3. Gas-liquid ratio: Can the gas gun effectively suck out the gas if it is pumped out?

4. Testing interface: The testing interface is qualified. To put it plainly, it can connect to the intake pipe of the testing instrument normally.

5. Other appearances: For example, is the oil gun return air hood is damaged?
