Description
Technical field
The utility model relates to Compressor Technology field, especially a kind of natural gas transport centrifugal compressor being installed on natural gas line conveying.
Background technique
Compressor be a kind of with internal-combustion engine or motor for power, atmosphere gas is compressed into pressurized gas and there are a kind of power plant of air flow energy.In natural gas transmission and distribution system, compressor is used for compressed natural gas, improves pressure or the conveying capacity of rock gas, and also usually the impurity in pipeline is replaced out, in order to avoid blocking pipeline with compressor transporting compressed gas body when cleaning pipeline.Therefore usually compressor is likened into the heart of Cemented filling.What current use was maximum is exactly reciprocal compressor, the shortcoming of reciprocal compressor is complex structure, bulky, maintenance load is large, due to power disequilibrium and air-flow impulse action, require equipment Foundations and Pipe installing anti-vibration measure, air inlet-exhaust valve is also had to be easy to wearing and tearing, the shortcomings such as part replacement is frequent in addition.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, the natural gas transport centrifugal compressor of flexible operation.
The utility model solves the technological scheme that its technical problem adopts: a kind of natural gas transport centrifugal compressor, comprises main body and end cap, is divided into suction port, induction chamber, room of outlet and air outlet in main body along rock gas course; Described induction chamber is built-in with the turbine disk, and turbine disk center is provided with main shaft, and main shaft one end connects the motor be arranged on outside main body, and the main shaft the other end is provided with wheel hub, and wheel hub outer peripheral surface is provided with guide vane wheel; Diffuser is provided with between described induction chamber and room of outlet.
Further, be provided with bearing outside the described turbine disk, bearing outside is provided with mechanical seal.
Further, described bearing and mechanical seal are set on main shaft.
Further, be fixedly connected with by clamping bolt between described main body and end cap.
Further, the part that described main body and end cap contact is provided with gasket seal.
The working principle of centrifugal compressor is for when main shaft impeller rotates, and gas is sucked by induction chamber, by quick runner to air work, the pressure of gas, speed, temperature is improved.When gas to be centrifuged after power throws away impeller with very high speed, enter in Diffuser.Owing to there being wide passage in Diffuser, the part kinetic energy of gas becomes pressure energy, and speed reduces and pressure improves.Then sucked by the second level again by bend and return channel, improve pressure further by the second level, compress step by step successively, reach rated pressure always, export finally by outlet pipe.Because temperature after gas compression raises, in order to reduce power consumption during compression high-temperature gas, in compression process, interstage cooler is also adopted to cool pressurized gas.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, and discharge capacity is large, compact structure, friction means is few, without to-and-fro motion, comparatively steady during work, without flow pulse phenomenon, flexible operation, be easy to realize automatic control, maintenance load is significantly less than reciprocal compressor.
