Affect the performance of hydraulic hose connector assembly structure and process factors

First, the composition of hydraulic hose connector assembly and the classification by the hydraulic hose connector assembly and the metal hose joint of two parts ( Figure l, 2). Mainly on working pressure range and form of connection hose and connectors to classify . ( Twenty {'), j Figure 1 withhold algae Hao Qian Figure 2 detachable 1 Press the working pressure range category 1 ) Low working pressure 3MPa the following , mainly cotton ( fiber ) braided hydraulic hose . Mainly used to control oil ,  Hydraulic tube fittings brake lines and some machine tools . 2 ) working pressure in pressure between the three one 10Mpa , primarily steel wire braided I, Type III Chase Drive ( towel 25 or more ) hydraulic hose . Mainly used in low pressure oil and return line . Ah 3 ) High working pressure at 10 ~ 31.SMPa of the question , mainly steel braided D25 below I, l, l 1990 l of type and wire winding pipe . Mainly used in high-pressure systems . 4 ) high pressure working pressure 31.SMPa above , mainly in the following wire diameter 31.5 Pipe . With the development of EHV power hydraulic machinery , its growing demand .
