So that the mechanical moving parts to stop or slow down the drag torque must be applied is called the braking torque. Braking torque is the design, selection based on the brake, and its size is determined by the type of machinery and work requirements of the decision. Brake friction material used on the (brake parts) directly affects the performance of the braking process, which will affect the performance of the main factors for the operating temperature and temperature rise speed. Friction material should have a high and stable coefficient of friction and good wear resistance. banjo fitting Metallic and non-metallic friction material sub categories. The former are commonly used cast iron, steel, bronze and powder metallurgy friction material, which has leather, rubber, wood and asbestos.

Corrugated metal hose technology history

  Since 1855, German inventor and manufacturer of the world's first one corrugated metal hose since, after one hundred years of development, its reliable sealing metal hose , pressure resistance , high temperature resistance , corrosion resistance and flexible , and many other properties, widely used in aviation, aerospace, nuclear energy , shipbuilding and new construction and other industrial sectors , a modern piping systems essential components. With the rapid development of modern industry , metal hose is used widely for metal hose requirements are also increasing, bound to the metal hose technology more and more research , the development of metal hoses generally have the following stages :
      Initially , people used animal skins sewn into a tubular structure to meet the needs of the struggle for production . After a fairly long period , to 70 end of the century , the Dutch Golden Gai Wan del brothers made ​​a longitudinal suture canvas hose , at the time of the fire service is widely used . Later, with the rubber in the international market and the emergence of vulcanization process of development, hoses and metal wire or twine and other fabrics Kai mounted hose come out. But the works of some steam , hot air type high temperature medium ; liquid hydrogen ,socketless fitting liquid oxygen, liquid helium cryogenic medium class ; gasoline, kerosene, acid , alkali and other corrosive media ...... If the hose to transport , of course not. Especially at high temperatures, it is more difficult to ensure the security and reliability .
      Therefore, it gradually to focus on the metal tube , the metal tube geometry to produce the corresponding corrugated external surface . In this way, both with the same flexibility with hose : but also has a high temperature, low temperature resistance , aging resistance, corrosion resistance. Thus, as the metal hose body metal bellows thus produced .
     1855 , first published in Germany in manufacturing bellows patents. It is used when making jewelry has some principles to manufacture bellows . 30 years later, the French and German cooperation in the development of new metal bellows , in August 1885 won the French and German patents.
     l894 , the kind of bellows structure has been improved : People metal band by using two different diameter, wound in the opposite direction . Thus, the stress state of the metal strip in the lower reaches equilibrium with each other to overcome the shortcomings of the spontaneous unfolding .
    In 1929, the structure of the bellows had another technological revolution , which completely solved the bellows filled pad due to bending when asbestos rope rubber band or changes in the grooves of uneven sealing performance loss problems , thus opening up a corrugated tube broad prospects for development .
    From the 1950s began , double, triple , multi-layered bellows. Especially very thin-walled stainless steel bellows developed rapidly . In order to meet the requirements , banjo fitting it is welded , electroforming , machining, hydraulic and mechanical spinning process method to manufacture a variety of bellows .
    Corrugated metal hose from the tube as the significance of the body in terms of the development of metal bellows , metal hose means development .

the factors that affect the high-pressure hose assembly

Affect the use of high-pressure hose assembly of many factors, following a brief introduction for everyone:

1, hose size
Hose diameter should be appropriate, too small diameter pipeline will increase the flow rate of the medium, the system heat, reduce efficiency, and will produce excessive pressure on the overall system performance, if the hose with hose clamps fixed or through spacer plates, etc., we should also pay attention to the outside diameter of the hose.

2, the temperature range
Users should be allowed in the hose quality specifications used within a temperature range of hose. If the working environment temperature exceeds this range, it will affect the life of the hose, which will greatly reduce the ability to withstand pressure. Operating ambient temperature is too high or too low, long-term system, we recommend using the hose jacket.

3, the chemical compatibility
If you use special hydraulic banjo fitting medium, users should ensure that their choice of hose assembly hose inner and outer, joints and O-ring compatible with the media.

4, working pressure
Generally refers to dynamic pressure hose hose in continuous maximum allowable working pressure. In accordance with the provisions of the relevant international standards for hydraulic hose safety factor is generally recommended working pressure of the hose is usually a quarter of the minimum burst pressure values.

5, the impact stress and fatigue life
The selection is based on the hydraulic hose system design maximum pressure value determined. As the hydraulic system pressure value is usually dynamic and sometimes impact pressure, impact pressure peak is much higher than the maximum system pressure. However, the system generally have a relief valve, the impact pressure of the hose will not seriously affect the fatigue life. For particularly frequent shock pressure of the hydraulic system, suggested the use of particularly resistant to impact pulsation hose products.

6, the friction
Hose when used usual contact or friction with hard objects, the proposed increase in the external hose spring jacket.
