Abstract
The utility model provides a helical -lobe compressor gas cylinder structure, it can solve the problem that general matching nature is poor, the processing cost is high that current helical -lobe compressor gas cylinder structure exists. It includes cylinder block body, its characterized in that: still including radially exhausting the drill way module, the drill way module of radially exhausting is opened there is radial exhaust drill way for it, and the exhaust side of cylinder block body is opened has the axial installation chamber, the drill way module of radially exhausting inlay adorn in the axial installation intracavity.
Description
Technical field
The utility model relates to helical-lobe compressor construction applications, is specially a kind of helical-lobe compressor block structure.
Background technique
Usually for different working condition requirements, need the different interior volume specific ratio helical-lobe compressor of design to match, and the interior volume specific ratio of compressor is mainly determined by the geomery of the rod radial air vent mouth of compressor cylinder block.Therefore the helical-lobe compressor than requiring is amassed for different content, also meet the demands with regard to needing to manufacture and design the cylinder block with difformity size rod radial air vent mouth, and be generally integrally casting part due to compressor cylinder block, the general matching which results in compressor cylinder block is poor, often also need to configure corresponding casting mould to manufacture the cylinder block with difformity size rod radial air vent mouth simultaneously, this also just causes the poor universality of cylinder block casting mould, the problem that processing cost is high, and also increase the management of cylinder block casting mould stock, maintenance cost.
Summary of the invention
The utility model provides a kind of helical-lobe compressor block structure, and it can solve the problem that general matching is poor, processing cost is high that existing helical-lobe compressor block structure exists.
A kind of helical-lobe compressor block structure, it comprises cylinder block body, it is characterized in that: it also comprises rod radial air vent mouth module, described rod radial air vent mouth module has rod radial air vent mouth, the exhaust side of described cylinder block body has axial installation cavity, and described rod radial air vent mouth module is flush-mounted in described axial installation cavity.
Further, be fastened by bolts between described rod radial air vent mouth module and described cylinder block body.
Further, located by positioning key between described rod radial air vent mouth module and described cylinder block body.
Further, located by locating stud between described rod radial air vent mouth module and described cylinder block body.
After adopting helical-lobe compressor block structure of the present utility model, it can assemble the module of the rod radial air vent mouth possessing respective shapes size in axial installation cavity according to the requirement of different interior volume specific ratios, thus the general matching of cylinder block body can greatly be improved, and it need for the corresponding rod radial air vent mouth module of requirement processing casting of different interior volume specific ratios, thus reduce the processing cost of casting mould and the volume of casting mould, also have the stock control and maintenance cost that reduce casting mould.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of helical-lobe compressor block structure of the present utility model;
Fig. 2 be by Fig. 1 A to and to assemble in correspondence the empty long-pending block structure schematic diagram than the rod radial air vent mouth module for Vi1 after half-twist;
