The software of bellows hose and finned bellows in the internal combustion motor cooler, set up one to one thousand steel bellows with discontinuous convex and concave form in the cooler shell of the diesel engine or among the two tube plates of the cooling core. The tube strategy and the welding method are employed to correct the tube plate at 1 end, so that the flow state of the cooling medium is changed, so as to boost the warmth transfer coefficient and improve the heat transfer performance. The creation is novel in idea, functional in approach, low in expense, trustworthy in performance, higher in warmth transfer effectiveness, non-scaling, extended in services lifestyle, and lower in thermal anxiety.

Strain In accordance to the real functioning strain of the hose, check out the nominal diameter and stress gauge of the corrugation to determine no matter whether to use the stainless metal mesh sleeve variety.
Nominal diameter of the size hose, select the kind of joint (largely flange link, thread connection, fast joint relationship) and dimensions, hose length.
According to vacuum bellows of the bellows hose, refer to the correct use and installation technique of the metallic hose and the ideal length of the hose in the course of settlement compensation. The calculation of the size of the hose is in various states of motion and the least bending occasions and bare minimum bending radius of the hose. The parameters are correctly selected and put in properly.
Temperature The operating temperature and selection of the medium in the hose the ambient temperature when the hose is functioning. When the temperature is substantial, the temperature correction coefficient of the functioning strain of the steel bellows at substantial temperature need to be used to figure out the force right after the temperature correction to determine the correct pressure degree.
The chemical qualities of the medium conveyed in the media hose, according to the corrosion resistance parameter table of the hose material, decide the material of the hose areas.
Vacuum hoses are mainly utilized in monocry stalline silicon production to attain negative vacuum.
