What is the function between the high oil tank of lubrication system and auxiliary oil pump?

The normal oil supply of the air compressor is undertaken by the main oil pump. It is connected to the gear shaft of the speed-increasing machine. If the machine set is suddenly cut off or stopped, the main oil pump will not be able to supply oil. But at this time, because the inertia of the air compressor is still rotating, it is easy to cause tile Research accident. In order to avoid this kind of accidents, high oil tank or auxiliary oil pump are set in the lubrication system for emergency. In addition, when starting or stopping normally, oil must also be supplied by auxiliary oil pump.
When driving, the oil pump should supply oil to the upper oil tank first. After the oil is filled with the oil tank, the oil will overflow from the hole on the upper oil return pipe and return to the oil tank. When the unit stops due to sudden power failure, after the oil pressure is lower than 0.05MPa (surface pressure), the high oil tank will supply oil to each lubricating point through the lower pipe;
Some compressor units are equipped with emergency backup auxiliary oil pump system driven by DC motor, which can automatically start the oil supply in case of power failure.
In a word, as long as the compressor is still rotating, it cannot leave lubricating oil for a moment. Various emergency measures are needed to ensure the safety of the equipment.
