Description
Technical field
The invention belongs to the technical fields of refrigeration compressor.It is more particularly related to which removably split type can
Dismantle seperated high-efficient compressor cylinder block.In addition, the invention further relates to dismountable split type detachable seperated Efficient Compressions
The assembly method of machine cylinder block.
Background technique
The cylinder block of existing compressor is generally to be provided with crescent moon above cylinder block cylinder body convenient for piston rod assembly
The design of slot, crescent is provided with locational space to piston pin and connecting rod assembly.But for compressor overall performance, this crescent moon
Slot is other than for the assembly of piston pin connecting rod, without other any practical significances；Simultaneously as the presence of crescent, needs
Crescent week, which makes a circle, is arranged chamfering, if chamfering is uneven or chamfering flange, it is most likely that compressor piston clamping stagnation is caused,
Whole compressor is caused to fail；What is more, the presence of this crescent, short to crankshaft by centrifugal force drawing in compressor and freeze machine oil
At the top of axis in splashing greasing, become the important channel that refrigerator oil enters refrigeration system, refrigerant enters refrigeration system
A part of volume can be occupied in the evaporator of system, condenser, influences to conduct heat, since refrigerant contaminated product makes to participate in refrigeration cycle simultaneously
Refrigerant quality reduce, unit mass refrigerating capacity reduction cause compressor refrigerating capacity reduce with COP value reduce, it is clear that also with society
High-efficient energy-saving environment friendly theory is advocated not to be inconsistent.
Summary of the invention
The present invention provides a kind of detachable seperated high-efficient compressor cylinder block, and the purpose is to overcome the piston clamping stagnation of compressor
Hidden danger, the refrigerating efficiency for improving compressor.
To achieve the goals above, the technical scheme adopted by the invention is as follows:
Upper cylinder body is arranged in detachable seperated high-efficient compressor cylinder block of the invention, including lower bottom base, the cylinder block,
The upper cylinder body fastens screw by upper cylinder body and is fastenedly connected on lower bottom base.
The cylinder head of the high-efficient compressor passes through the cylinder head gasket being sequentially arranged, valve board assembly, suction valve chip, valve
Plate gasket is connect with the upper cylinder body.
Inhaling silencer is arranged in the high-efficient compressor；The inhaling silencer is mounted on the limit of cylinder head air-breathing
Side.
It is described the present invention also provides a kind of detachable seperated high-efficient compressor cylinder block, including level-one noise elimination lower bottom base
Level-one noise elimination upper cylinder body is arranged in cylinder block, and the level-one noise elimination upper cylinder body fastens screw by upper cylinder body and is fastenedly connected in level-one
On noise elimination lower bottom base；Level-one anechoic room and helmholtz resonance chamber is respectively set in the two sides of the level-one noise elimination upper cylinder body.
The side of the level-one anechoic room is fastened with reactive muffling room coil pipe by screw.
The cylinder head of the high-efficient compressor passes through the cylinder head gasket being sequentially arranged, valve board assembly, suction valve chip, valve

Inhaling silencer is arranged in the high-efficient compressor；The inhaling silencer is mounted on the limit of cylinder head air-breathing
Side.
The present invention provides a kind of detachable seperated high-efficient compressor cylinder block again, including lower bottom base, the cylinder block are set
Upper cylinder body is set, the second level noise elimination upper cylinder body fastens screw by upper cylinder body and is fastenedly connected on lower bottom base；Described two
The same side setting level-one anechoic room and second level anechoic room of grade noise elimination upper cylinder body.
The cylinder head of the high-efficient compressor passes through the cylinder head gasket being sequentially arranged, valve board assembly, suction valve chip, valve
Plate gasket is connect with the second level noise elimination upper cylinder body.
Inhaling silencer is arranged in the high-efficient compressor；The inhaling silencer is mounted on the limit of cylinder head air-breathing
Side.
The second level anechoic room is connected with the three-level noise elimination coil pipe with reactive muffling structure, forms three-level noise elimination structure.
In order to realize goal of the invention identical with above-mentioned technical proposal, the present invention also provides above-described detachable fissions
The assembly method of high-efficient compressor cylinder block, technical solution are that the process of this method is as follows:
After determining piston and upper cylinder body cylinder holes, crankshaft long axis and lower bottom base axis hole, the macropore of connecting rod and crank throw group, first
Piston rod part is assembled and is completed；It is inserted in crankshaft crank by correct group to the big nose end of connecting rod, and is guaranteed upper on upper cylinder body
After lower bottom base Luo pit on cylinder body mounting hole and lower bottom base corresponds, at this moment piston is inserted in the cylinder holes of upper cylinder body again；
During being inserted in, after in piston nose, about 3~5mm enters the cylinder holes of upper cylinder body, to two upper cylinder halfs of connection
Body fastens the pre-fastening moment that screw applies 3Nm, while turning crankshaft, checks whether pump housing feel is flexible, continues to upper cylinder body
Fastening screw continues to increase Tightening moment, so that fastening force is away from until reaching 10Nm；
Entirely to upper cylinder body fastening screw apply fastening force away from during, want continuous turning crankshaft always, make piston
