The utility model discloses novel structure, reasonable in design, radial packing force is even and unanimous with leakage pressure law, makes axle sleeve bearing area pressurized even to it is little and even to make the axle sleeve wearing and tearing, be equipped with the oil storage chamber in addition on the gland, can carry out effectual replenishment, increase of service life to the lubricating oil of loss in packing.
Description
Technical field
The utility model relates to low temperature BOG and reclaims Compressor Technology field, particularly relates to a kind of low temperature BOG and reclaims packing seal structure of compressor.
Background technique
Low temperature BOG reclaims compressor packing and seals because the feature having structure simple, easy for assembly, disassembly and maintenance and with low cost is widely applied.In existing technology, filler loads after Stuffing box, and gland is made axial compression to it and thus produced radial force, and with axle close contact.Meanwhile, the oiling agent flooded in filler is extruded, oil film is formed between surface of contact, and the recess do not contacted forms little oil groove, there is thicker oil film, when axle and filler have relative movement, irregular labyrinth together with contact position forms with non-contact position, play a part to stop liquid to flow dew, i.e. labyrinth effect.Obviously, good sealing is to keep good lubrication and suitable compression, if insufficient lubrication or press through and tightly oil film all can be made to interrupt, causes between filler and axle and forms dry friction, finally cause excessively heated axle and occur heavy wear; In addition, existing packing seal structure, when lubrication oil consumption, can not get follow-up supplementing, causes lubrication effect poor, reduce working life, adds the cost that low temperature BOG reclaims compressor operating.
Summary of the invention
The utility model object is to provide a kind of low temperature BOG to reclaim packing seal structure of compressor, and radial compacting force is even and consistent with leak pressure rule, and the lubricant oil in filler is able to follow-up supplementing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of low temperature BOG reclaims packing seal structure of compressor, comprises gland, shaft seal cavity cover, shaft seal, filler, shaft seal cavity cover bolt, spring, adjusting nut; Described filler is filled between shaft seal cavity cover and axle, and filler is wrapped in the surrounding of axle; Described gland is provided with shoe cream room, is filled with lubricant oil in shoe cream room, and shoe cream room side is provided with oil outlet, and oil outlet place is provided with overflow net, and overflow is provided with several trickle cellular apertures on the net; Described gland to be overlapped with shaft seal cavity by shaft seal cavity cover bolt and is connected, and shaft seal cavity overlaps the bolt the other end and is provided with adjusting nut, is provided with spring between adjusting nut and gland; Be reserved with the adjustment chamber moved axially for shaft seal cavity cover between described shaft seal and gland, between shaft seal and shaft seal cavity overlap, be provided with seal ring.
Further, described filler is the soft packing of oil immersion asbestos packing.
Further, described seal ring is " O " RunddichtringO, and quantity is 2-4.
Further, described overflow net material is stainless steel, and overflow mesh eyes size is 200-300 order.
Beneficial effect: compared with original technology, a kind of low temperature BOG of the present utility model reclaims packing seal structure of compressor novel structure, reasonable in design, and radial compacting force is even and consistent with leak pressure rule, make axle sleeve pressure-bearing surface pressurized even, thus it is little and even that axle sleeve is worn and torn; This outer press cover is provided with shoe cream room, effectively can supplement, increase the service life to the lubricant oil of loss in filler.
