Technical Field

The invention relates to the technical field of oil pump connection structures of vapor compressors, in particular to a connection structure of a mechanical oil pump for a tooth type compressor.

Background

The steam compressor is a key device for compressing steam generated in the production process in a heat recovery system to improve the temperature and pressure of the steam, and realizes pressurization and temperature rise of the low-pressure or low-temperature steam so as to meet the temperature and pressure requirements of corresponding processes and projects. At present, a main oil pump of a centrifugal compressor supplies oil to drive a driven gear through a main shaft gear, so that the main oil pump is driven to work. The existing main oil pump mounting structure is basically as shown in fig. 2, a main oil pump is fixed with a gear box through a main oil pump connecting plate, and the main oil pump is fixedly connected with a driven gear in the gear box. In some places with bad operation conditions and large dust, the service life of the main oil pump is short, and the gears inside the compressor are not damaged basically. In the existing main oil pump mounting structure, if the main oil pump is damaged, relevant parts in a gearbox need to be disassembled, so that the main oil pump is not convenient to replace on site.

Disclosure of Invention

The invention aims to provide a connecting structure of a mechanical oil pump for a tooth type compressor, and solves the problem that the main oil pump is inconvenient to replace in the existing main oil pump mounting structure.

In order to achieve the above object, the basic scheme of the invention is as follows:

the utility model provides a connection structure for mechanical type oil pump of tooth compressor, includes the connecting plate, still includes bearing frame and pivot, the bearing frame can be dismantled with the connecting plate and be connected, the connecting plate is used for fixed main oil pump, the pivot is rotated and is connected in the bearing frame, driven gear in pivot one end and the gear box is fixed, the pivot other end can be dismantled and drive main oil pump work with main oil pump.

Further, the bearing seat is fixedly connected with the connecting plate through bolts.

Further, the main oil pump is fixedly connected with the connecting plate through bolts.

The beneficial effect of this scheme: the main shaft gear drives the driven gear, the driven gear drives the bearing in the bearing seat to rotate, and finally the main oil pump is driven to rotate, so that lubricating oil is pumped from an inlet of the main oil pump to an outlet. When the main oil pump is damaged and needs to be replaced independently, the main oil pump only needs to be detached from the connecting plate, the main oil pump can be replaced by detaching the rotating shaft and the main oil pump, and a box cover and the like on a gear box of the compressor do not need to be detached.
