Lid mounting hole aligns with the protecgulum screwed hole on protecgulum positioning seat, is connected by screw bolts between compressor housing and protecgulum, installation
Process is convenient and swift.Shell uses Split type structure, and compressor housing and protecgulum are cast and machined respectively, compressor complete machine
During assembling, it is convenient to observe the situation of compressor, improve the convenience dismantled when assembling and maintenance.
Preferably, the other end of compressor housing is provided with some floral disc positioning seats around opening arrangement, described flower
The floral disc screwed hole with the axially in parallel arrangement of compressor housing is provided with disk positioning seat.The other end of compressor housing sets floral disc
Positioning seat, floral disc positioning seat is interior to set floral disc screwed hole, facilitates compressor housing to be attached with floral disc.
Preferably, the both sides of described compressor housing are respectively equipped with the mounting seat extended to horizontal direction, the peace
Dress seats against the bottom of nearly compressor housing, and the outer end of mounting seat is provided with the mounting hole arranged vertically.Peace is set on compressor housing
Seat is filled, mounting hole is set in mounting seat, in order to which compressor is installed.
Preferably, the edge of the protecgulum is provided with installs projection with the protecgulum of protecgulum positioning seat position correspondence, before described
Lid installation is raised consistent with the protrusion height of protecgulum positioning seat, and described protecgulum mounting hole is arranged in protecgulum installation projection.Before
Lid installs the protecgulum positioning seat position correspondence on raised and compressor housing and the protrusion height being consistent, and is carried when placing
High compressor and the contact area of placed side, ensure that stable in placement is reliable.
Preferably, the middle inside of the protecgulum is provided with positioning boss, the middle part of the positioning boss is provided with positioning hole.
The centrally disposed positioning hole of positioning boss, positioning support can be carried out to compressor rotation shaft.
The beneficial effects of the utility model are：Casting processing and the Product Assembly difficulty of compressor case are reduced, is improved
Production efficiency, reduces production cost.
