Description

Technical Field

[0001] The utility model relates to the technical field of refueling devices, in particular to an air-locking type refueling device. Background Art

[0002] The air-locking refueling device is a device used to prevent air from entering the fuel tank during the refueling process. This device is usually used between the refueling gun and the fuel tank interface. Its function is to ensure that during the refueling process, the air inside the fuel tank will not be added along with the oil, so as to avoid excessive pressure inside the fuel tank or air mixing into the oil, thereby ensuring the purity of the oil and the smoothness of the refueling process.

[0003] However, Coal Powder said that the reducer was found to be leaking oil or lacking oil during the operation of the metering unit. When the metering unit was in operation, there was 2.0 bar of assisted compressed air in the gearbox, and the refueling port was opened in a positive pressure state, making it difficult to add oil. If the gearbox is in a state of low oil or lack of oil for a long time, it is easy to cause the metering unit to run noisy, and in severe cases, the gearbox will be damaged and the kiln will be stopped.

[0026] Working principle: The device is connected to the gearbox through the third connecting nut 14. When lubricating oil needs to be added to the oil cup 8, the balance valve 13 is closed, the sealing valve 7 is opened, the lubricating oil is injected through the refueling bin 1, and filtered through the filter 4 to prevent the impurities in the lubricating oil from damaging the gearbox. The filtered lubricating oil flows into the oil cup 8 through the first connecting pipe 6 for storage. After the oil cup 8 is filled with lubricating oil, the sealing valve 7 on the oil cup 8 is closed to keep the lubricating oil inside the oil cup 8 in a sealed state. When filling the gearbox with oil, the balance valve 13 on the gearbox is slowly opened. According to the principle of pressure balance, the air pressure in the inner cavity of the sealing cabin is balanced. At this time, the lubricating oil will naturally flow into the gearbox, so that the gearbox is well lubricated.
