1. Whats wrong with the slow oil output of the refueling truck?

2. How does the gas turbine flowmeter inject oil? The method of oil injection for gas turbine flowmeter is as follows: Gas turbine flowmeter is a precision instrument that integrates sensors and volume correction instruments. Its internal mechanical transmission part needs appropriate lubrication to ensure normal operation and extend service life. The oil injection process is crucial for maintaining the performance of the flowmeter.

1. Preparation before oil injection: First, it is necessary to confirm whether the gas turbine flowmeter is equipped with an oil injection system.

. Most contemporary gas turbine flow meters come with an oil lubrication system, but there are still a few products that may not have this system. For flow meters without an oil injection system, maintenance should be carried out according to the manufacturers recommendations. Choose appropriate lubricating oil: Instrument specific oil should be used for oil injection to ensure compatibility with the internal materials of the flow meter and avoid negative impact on the performance of the flow meter. Prepare oiling tools: Depending on the design of the flowmeter, specialized oiling tools or equipment such as oiling guns, lubrication cups, etc. may need to be prepared.

2. Oil injection steps: Before injecting oil, the flow meter should be turned off and its power should be cut off to ensure safe operation.

. Find the oil injection port: Find the oil injection port on the flow meter, which is usually located on the cautious housing of the flow meter and labeled accordingly. Clean the oil injection port: Before injecting oil, clean the oil injection port wit

h a clean and tidy cloth or a tissue to prevent impurities from entering the inside of the flowmeter. Inject lubricating oil: Use an oil injection tool to inject an appropriate amount of instrument specific oil into the oil injection port. The oil injection amount should strictly follow the manufacturers recommendations to avoid excessive or insufficient lubricating oil having adverse effects on the performance of the flowmeter. Check the oil injection effect: After the oil injection is completed, check whether the flow meter can operate normally and observe whether there is any oil leakage. If there are any abnormalities, they should be dealt with promptly.

III. Oil injection cycle and precautions Oil injection cycle: The oil injection cycle depends on the cleanliness of the gas and the operating environment of the flowmeter.

. Generally speaking, the gas turbine flowmeter in the station should be equipped with a lubrication cup, with a lubrication cycle of one month, and 4 strokes should be pulled during each lubrication. For gas turbine flow meters in urban pipeline networks, due to their low working pressure (about 0.2-0.4MPa), instrument specific oil is generally added every three months. Attention: Oil injection should be avoided during the operation of the flowmeter to prevent lubricating oil from splashing out or damaging the internal parts of the flowmeter. The oil injection amount should be strictly controlled to avoid excessive or insufficient lubricating oil having a negative impact on the performance of the flowmeter. The cleanliness and quality of lubricating oil should be checked regularly, and if necessary, it should be replaced in a timely manner. During the oil injection process, relevant safe
