Abstract
The utility model discloses an axle stopper, including toper drum and roof, the one end of toper drum is held for the heavy -calibre, and its other end is small -bore end. The roof is located the small -bore end of toper drum, and its edge becomes integrative with the small -bore end fixed connection of toper drum, and is closed with the small -bore end of toper drum. The heavy -calibre end of toper drum is uncovered, and the heavy -calibre end of toper drum has a plurality of rectangular form breach that is annular evenly distributed, and the axis direction that the toper drum is followed to each rectangular form breach extends to the middle part of toper drum. The utility model discloses a compressor piston axle subassembly has the piston axle, dispose above -mentioned axle stopper in the bell mouth of piston axle. The assembly of axle stopper is in the bell mouth of piston axle, and the hole that can prevent refrigerant oil to pass through the piston axle gets into refrigerant circuit to be mixed with the refrigerant, keeps the efficiency of air conditioner unchangeable. It is unchangeable to keep being used for lubricated with sealed refrigerant oil volume, makes spare part obtain better lubrication and prevents that the refrigerant from revealing.
Description
Technical field
This utility model relates to Compressor Technology field, is specifically related to a kind of axle plug and compressor piston shaft assembly.
Background technology
Swinging compressor of air conditioner, is typically made up of important spare parts such as compressor top cover, shell, motor rotor, pumping, bottom, motor stator, filtering flask and foot rests.Air-conditioner system includes compressor, needs to be filled with coolant in the refrigerant pipeline of compressor, just can make, in compressor operation, to reach predetermined effect.Compressor is when high rotation speed operation, and the refrigerator oil being used in body lubricating can enter coolant loop by the endoporus of piston shaft.Owing to refrigerator oil is not involved in heat exchange, the refrigerator oil being mixed in coolant can cause the efficiency of air-conditioner to reduce.Meanwhile, the internal oil level of compressor reduces, and the fridge oil mass being used for lubricating and sealing reduces, and causes parts wear and secondary refrigerant leakage.
Utility model content
Being directed to the defect that above-mentioned prior art exists, a purpose of the present utility model is to provide a kind of axle plug, and this axle plug stops refrigerator oil to enter refrigerant pipeline and mixes with coolant, protects the internal fridge oil mass being used for lubricating and sealing of compressor constant.
To achieve these goals, the technical solution of employing is this utility model:
A kind of axle plug, including tapered cylinder and top board, one end of described tapered cylinder is heavy caliber end, and its other end is small-caliber end.Described top board is positioned at the small-caliber end of tapered cylinder, and its edge is fixedly connected into one with the small-caliber end of tapered cylinder, is closed by the small-caliber end of tapered cylinder.The heavy caliber end of tapered cylinder is uncovered, and the heavy caliber end of tapered cylinder has the most equally distributed multiple strip breach, and each strip breach extends to the middle part of tapered cylinder along the axis direction of tapered cylinder.
Preferably, the number of described strip breach is 3～7, and each strip breach is uniformly distributed on the barrel of tapered cylinder.
Another purpose of the present utility model is to provide a kind of compressor piston shaft assembly.
A kind of compressor piston shaft assembly, has piston shaft, is configured with above-mentioned a kind of axle plug in the bellmouth of described piston shaft, and the opening end of axle plug is towards the heavy caliber end of bellmouth.
By using technique scheme, Advantageous Effects of the present utility model is: above-mentioned axle plug is assemblied in the bellmouth of piston shaft, it is possible to stoping refrigerator oil to enter coolant loop by the endoporus of piston shaft and mix with coolant, the efficiency keeping air-conditioner is constant.Simultaneously, additionally it is possible to prevent the fridge oil mass within compressor from reducing, keep the fridge oil mass being used for lubricating and seal constant, make parts preferably be lubricated and prevent secondary refrigerant leakage.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of a kind of axle plug in this utility model.
Fig. 2 is the right TV structure schematic diagram of a kind of axle plug in this utility model.
Fig. 3 is the structural principle schematic diagram of a kind of compressor piston shaft assembly in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
Embodiment 1, in conjunction with Fig. 1 and Fig. 2, a kind of axle plug, including tapered cylinder 1 and top board 2, one end of described tapered cylinder 1 is heavy caliber end, and its other end is small-caliber end.Described top board 2 is positioned at the small-caliber end of tapered cylinder 1, and top board 2 edge is fixedly connected into one with the small-caliber end of tapered cylinder 1, is closed by the small-caliber end of tapered cylinder 1, and the heavy caliber end of tapered cylinder 1 is uncovered.The heavy caliber end of described tapered cylinder 1 has the most equally distributed 5 strip breach 3, and each strip breach 3 is respectively positioned on the barrel of tapered cylinder 1, and each strip breach 3 extends to the middle part of tapered cylinder 1 along the axis direction of tapered cylinder 1.The width of all of strip breach 3 is the most identical, and the degree of depth is the most identical.
Embodiment 2, in conjunction with Fig. 3, a kind of compressor piston shaft assembly, there is piston shaft 4, in the bellmouth 5 of described piston shaft 4, be configured with a kind of axle plug 6 described in embodiment 1.Axle plug 6 loads inside it by the heavy caliber end of the bellmouth 5 of piston shaft 4, and the opening end of described axle plug 6 is towards the heavy caliber end of bellmouth 5.Piston shaft 4 is after assembling completes, and the heavy caliber end of bellmouth 5 is its lower end, and small-caliber end is its upper end.Described bellmouth 5 near the diameter of the part of small-caliber end less than the external diameter of top board 2, between outer wall and the inwall of bellmouth 5 of axle plug 6, there is gap, the heavy caliber end of tapered cylinder 1 is acted in an unreasonable way elastic deformation, it is stuck in bellmouth 5, gas can be discharged from the small-caliber end of bellmouth 5 through tapered cylinder 1 barrel strip breach 3.
During piston shaft assembly high-speed rotation, refrigerator oil in compressor block can be followed gas and be moved to the small-caliber end of bellmouth 5, refrigerator oil arrives axle plug 6, axle plug 6 can limit refrigerator oil and continue up, along with axle plug 6 accumulated inside refrigerator oil gets more and more, can form oil droplet, oil droplet is under the action of gravity of himself, and the inwall along bellmouth 5 falls.Axle plug 6 can effectively stop refrigerator oil to be discharged from the upper end of bellmouth 5 with gas, and enter coolant loop and mix with coolant, causes the efficiency of air-conditioner to reduce.Axle plug 6 can also prevent the fridge oil mass within compressor from reducing, and keeps the fridge oil mass being used for lubricating and seal constant, makes parts preferably be lubricated and prevent secondary refrigerant leakage.
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, change that those skilled in the art are made in essential scope of the present utility model, retrofits, adds or replaces, and also should belong to protection domain of the present utility model.
