Prerequisite: you have to know the most basic fitting tips

Threaded pipe fittings is plays a very important role in our daily lives, like air, do not get our attention, but we were inseparable, our production and our lives without it. Since it is so closely with our life and production, so we need to get some knowledge about it, in order to enrich their knowledge of life. Now, let us get to know about the basics of pipe fittings.

Pipe Fittings

Pipe Fittings

Meaning, pipe fittings
Threaded fittings can be the same type, the pipes of the same diameter, dispersed the machinery industry that connects components, fittings connect, control, transformation, diversion, seal, supporting role, occupy an important position in industry. It can have a different classification according to different criteria.
Second, the classification of fittings
1, classified by use:
Threaded pipe fittings is widely applied in industry, so pipes have many uses, some pipe fittings are used to connect to, such as flanges, Union, pipe clamps, ferrules, etc. Is used to change the direction of the pipes, elbows and bends. Some are used to vary the diameter of, such as adjustable reducers, reducing elbows, pipes, etc. Some is used to increase the diameter of the branch, such as three-way and four-way. Is used to seal the pipe diameter, such as gaskets, wire, plug, seal top. There were used to fix pipes, such as rings, brackets, tubes, etc.
2, according to the connection method classification
Pipe fittings in different applications depending on actual connection, mainly in the following categories: weld pipe fittings, threaded fittings, ferrule parts, socket, hot-melt pipe fittings and so on.
3, classified by materials
Fittings made of different materials, mainly made of steel, stainless steel, plastic, rubber and synthetic materials, therefore, will have a cast iron pipe fittings, cast iron pipes, stainless steel pipes, plastic pipe, rubber pipes, graphite pipe fittings and other fittings made from synthetic materials, and so on.

Bevel Gearbox fault occurs in Bevel Gearboxs and bearings

Bevel Gearbox  in the acceleration phase of the vibration signals often contain more information than constant speed, so in the field of construction machinery, usually standard mechanical speed tests as part of the testing process.

Bevel Gearbox

Bevel Gearbox

Vibration acceleration signal belongs to the non-stationary signals, speed on the changes in the spectrum of frequency components is ambiguous, this ambiguity will cause amplitude measurement error of frequency components, makes the traditional spectral analysis to achieve effective results. If artificially such signals are assumed to be cyclostationary signal processing, the result will have serious frequency ambiguity.
In rotating machinery, with phase speed of axis at the speed of change is closely related to the vibration signal and speed, order analysis based on speed signal extraction of other related harmonic components, filtering extraneous noise and fund projects. Traditional order spectrum analysis to fault the Bevel Gearbox is less information to identify high and Autoregressive parameter of AR model to fault signals are very sensitive to changes, it contains a great deal of fault features, can be used for fault diagnosis of Bevel Gearbox. Through the Bevel Gearbox test vibration signal analysis and comparison, the recognition speed, failure rate is high, verify the order AR model and combination of SVM can be effectively applied to Bevel Gearbox fault diagnosis of Bevel Gearbox box, extends the range of AR model, provides a new method of fault diagnosis in  Bevel Gearbox(http://www.gear-system.com).
