Abstract
Provided is an exhaust connection structure of a supercharger of a diesel. The exhaust connection structure comprises an exhaust pipe, the supercharger, an exhaust flange, sealing rings, a silencer and a silencer support, wherein the supercharger is fixedly connected to the exhaust pipe of an engine and connected with the large end of the exhaust flange through bolts, the exhaust flange is connected with the air inlet of the silencer through the sealing rings, the silencer support is connected with the exhaust pipe, the top surface of the silencer support is connected with a base of the silencer, each sealing ring is provided with an opening, and the openings of the four sealing rings are alternately formed in a 90-degree mode. By means of the exhaust connection structure, connection between the supercharger and the silencer is flexible connection, the disassembly and assembly difficulty is effectively lowered, cold looseness and air leakage do not happen easily on the connection portion of the supercharger and the silencer, the connection reliability is greatly improved, mating main machine products can be safely used under the condition of long-term vibration, and the overall reliability of the diesel is improved.
Description
Technical field
The utility model belongs to engine art, relates to a kind of diesel pressure booster, relates in particular to a kind of diesel pressure booster exhaust linkage structure.
Background technique
At present, the boosting type diesel pressure booster that China produces adopts flange to be connected and seam Placement with silencing apparatus more.Because flange connects to be connected to be with seam, be rigidly connected, after long-term use, usually occur causing due to high temperature action the phenomenon of component craze and transfiguration, affect user and use.And assembling is also inconvenient, has affected product quality.Along with the upgrading of discharging standards, supercharging and middle cold mould diesel engine will substitute natural aspiration diesel engine gradually, therefore, design a kind of exhaust linkage structure that can connect reliably pressurized machine and silencing apparatus and will be very important.
Model utility content
The utility model object is to provide a kind of reliable operation, rational in infrastructure, installation and maintenance diesel pressure booster exhaust easily linkage structure.
The technical solution of the utility model is: diesel pressure booster exhaust linkage structure, comprising: outlet pipe, pressurized machine, exhaust flange, seal ring, silencing apparatus, muffler bracket; Pressurized machine is fixedly connected on waste pipe, and is connected with the major part of exhaust flange with bolt, and exhaust flange is connected with silencing apparatus suction port by seal ring, and muffler bracket is connected with outlet pipe, and muffler bracket end face is connected with the base of silencing apparatus.
Described seal ring has opening, and the opening installation of staggering in 90 ° mutually of Si road seal ring is set.
The utility model can reach following good effect after adopting technique scheme: can make the flexible connection that is connected between pressurized machine and silencing apparatus, can effectively reduce dismounting difficulty, making its joint be difficult for producing cold conditions gets loose and gas leak phenomenon, connection reliability improves a lot, matched host machine product can be used safely under Long-term Vibration operating mode, improved Diesel Engine Complete Machine reliability.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model diesel pressure booster exhaust linkage structure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Fig. 1, the utility model mainly comprises: outlet pipe 1, pressurized machine 2, exhaust flange 3, seal ring 4, silencing apparatus 5, muffler bracket 6; Pressurized machine 2 is fixed by bolts on outlet pipe 1, and exhaust flange 3 is fixed by bolts on the exhaust volute of pressurized machine 2, and silencing apparatus 5 is fixed by bolts on outlet pipe 1 with support 6, and seal ring 4 is arranged on exhaust flange 3.
Seal ring 4 has opening, and the opening of four road seal rings 4 is in 90 ° staggering mutually.Seal ring 4 has compressibility, compresses rear and silencing apparatus 5 suction ports formation sealing strips, can effective sealing diesel pressure booster high-temperature exhaust air.
During diesel engine work, the turbo driving that waste gas promotes in pressurized machine 2 by outlet pipe 1, the waste gas of turbine back enters silencing apparatus 5 by exhaust flange 3, after silencing apparatus 5 discharged to atmosphere, complete whole exhaust process, the connection of exhaust flange 3 and seal ring 4 flexibilities pressurized machine 2 and silencing apparatus 5, make high temperature, high pressure exhaust gas not revealing under prerequisite discharged to atmosphere, complete diesel exhaust dispatch process.
The utility model can effectively solve flange, yoke configurations install and using process in the stress that occurs cause component problem of Cracking, effectively improved the reliability of component in vent systems, rational in infrastructure, easy maintenance.
