Description
Technical Field
The utility model belongs to the technical field of lubricating devices, and particularly relates to a lubricating device for a centrifugal compressor.
Background
The main components of centrifugal compressors for compressing gas are impellers rotating at high speed and diffusers with progressively increasing flow areas. The centrifugal compressor works in the principle that the impeller works on gas, and mechanical energy is converted into pressure energy of the gas by utilizing centrifugal boosting effect and speed-reducing diffusion effect in flow channels of the impeller and the diffuser.
The centrifugal compressor is composed of a rotor, a stator, a bearing and the like. Parts such as impellers are sleeved on the main shaft to form a rotor, and the rotor is supported on a bearing and driven by a power machine to rotate at a high speed. The stator comprises a shell, a partition plate, a seal, an air inlet chamber, a volute chamber and the like. The fixing elements such as a diffuser, a bend, a reflux device and the like are formed between the partition plates. In the working process of the centrifugal compressor, the motor drives the main shaft and the impeller to rotate, the bearing supports the main shaft, and the bearing in the shell and the main shaft lack lubrication, so that the friction is large, abrasion is easy to exist, and the use of the centrifugal compressor is affected.
Chinese utility model patent: the utility model provides a CN202120181496.2, publication number CN214221589U discloses a lubricating arrangement for centrifugal compressor, including centrifugal compressor body and oil supply tank body, an oil filler point has been seted up on the centrifugal compressor body casing, and on the centrifugal compressor body casing and be located oil filler point department fixed mounting has a block subassembly, the fixed intercommunication in top of oil supply tank body has an oil inlet pipe, be connected with an oil-well pump on the oil inlet pipe, the one end fixed intercommunication that oil inlet pipe kept away from the oil supply tank body has a link pipe, the fixed lantern ring of first fixed lantern ring and the fixed lantern ring of a second of having cup jointed of week side of link pipe, be equipped with an oil outlet pipe between centrifugal compressor body and the oil supply tank body, the block subassembly includes a fixed section of thick bamboo. The connecting end pipe, the first fixed lantern ring, the second fixed lantern ring and the clamping assembly are combined for use, so that the connecting end pipe can be conveniently installed and detached, the working efficiency of staff is greatly improved, and the connecting end pipe is easy to market;
The lubricating device is lubricated through an external lubricating system in the actual use process, equipment is huge and maintenance is complicated, and meanwhile, excessive lubricating oil is easy to remain in the compressor, so that the lubricating device for the centrifugal compressor is designed to solve the problem.
