How to adjust the gas-liquid ratio of Heineken oil and gas recovery gun

The adjustment method of this situation is as follows:

Tighten the adapter on the nozzle of the refueling gun, and add sealing washers at both ends of the adapter to prevent air leakage. The adapter is connected with the gas flowmeter, and the gas flow first passes through the gas flowmeter and then enters the oil tank through the oil and gas collection hole on the refueling gun.

In the process of adjustment, it is often found that the gas-liquid ratio value is outside the interval, so it is necessary to adjust the oil and gas recovery gun properly. If the gas-liquid ratio exceeds the standard, the test should be repeated for confirmation. If the difference between the two test results is less than 5%, it can be considered that the test is correct, and the average value of the two tests is recorded as the test result.
