Technical field
The utility model belongs to the turbomachinery field, relate to a kind of bearing bag that is arranged in the compressor air inlet runner, be furnished with the cod that prevents the compressor drum axial motion in this bearing bag and guarantee the radial bearing that compressor runs well, and the sensor that rotor and bearing arrangement thereof are carried out bearing temperature, shaft vibration, axial displacement monitoring.
Background technique
The bearing bag of plain edition compressor is positioned at outside the compressor air inlet runner.If it is arranged in the compressor air inlet runner, because knowing from experience, bearing bag inner chamber forms little negative pressure, the lubricant oil in the bearing bag is revealed from the mating face easily, enters in the air inlet runner, thereby pollutes compressor medium.
Summary of the invention
The purpose of this utility model is, a kind of bearing bag that is arranged in the compressor air inlet runner is provided, and this bearing bag is installed in the compressor air inlet runner, and the lubricant oil in the bearing bag can not revealed from the mating face, can not pollute compressor medium.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of bearing bag that is arranged in the compressor air inlet runner, this bearing bag is installed in the end of the compressor drum in the suction chamber, it is characterized in that, it comprises the bearing inclusion, be provided with cod and radial bearing in the bearing inclusion, on the split of bearing inclusion, have outside groove and inboard groove, outside groove communicates with sealed air-space, blanket gas side trench outside forms sealing gland one, and the blanket gas pressure of sealing gland is a little more than the compressor suction pressure, and bearing inclusion one side leaves the blanket gas import, blanket gas is introduced this sealing gland from being sealed into gas port, forms the sealing gland ring; Be bumped into O type circle in the inboard groove, form static seal; In the bearing inclusion, also have the pressure tap of a blanket gas and the relief opening of a blanket gas, make blanket gas can get rid of smoothly and do not enter in a large number in the bearing inclusion, and keep certain pressure; Bearing inclusion one side also leaves throat's differential pressure and surveys mouth, blanket gas relief opening and measurement axis to the shaft position sensor lighting outlet mouth of bearing temperature, compressor drum and the axle temperature degree sensor lighting outlet mouth of radial bearing; The place is equipped with axis vibration sensor at radial bearing, also has the radial bearing filler opening on the radial bearing; Also has the cod filler opening on the cod; Downside in the bearing inclusion is equipped with the import of two rotor jacking high pressure oils.
The bearing bag that is arranged in the compressor air inlet runner of the present utility model, having good sealing effect lubricant oil does not reveal, sealing tolerance and adjustable in pressure control, be difficult for losing efficacy, characteristics such as long service life can be applied to the turbomachinery field, realized owing to shorten axial dimension (axial dimension restriction), the bearing bag is arranged in the purpose of air inlet runner, and processing, installation, operation, easy maintenance, the suitable popularization.
