【Q&A Question 070】June 29, 2016: Why cannot the liquid level in the lubricating oil tank of the cyclic hydrogen compressor be kept too high? The answer key will be available after responding; scoring is based on answering the key points. 1. If the circulation pump stops, the lubricating oil from the unit and that in the high-level oil tank will flow into the oil tank, causing the lubricating oil in the tank to overflow. 2. A too high oil tank level wastes lubricating oil; maintaining an appropriate level is sufficient.
An excessively high oil level causes the fuel tank temperature to rise, generating excessive heat. The increase in oil temperature affects the lifespan of the fuel; it also makes the fuel more prone to emulsification. Additionally, a high oil level increases the resistance encountered by the oil wiper
Prevent the oil in the system from returning to the tank during shutdown and causing overflow
If the liquid level is too high, it will cause oil to spray out during operation, right?
If the liquid level is too high, there is not enough space in the tank for the oil and gas to evaporate; in particular, the water vapor that seeps out cannot be expelled
To prevent volume expansion of the lubricating oil due to temperature rise,
The control level is set too high; in the event of a power outage, it is necessary to take into account that oil from the upper tank may flow into the main tank to prevent it from overflowing
Why can’t the liquid level in the lubricating oil tank of the cyclohydrogen compressor be kept too high? Is it because the air flow space at higher altitudes becomes smaller, which affects the cooling effect?
