Abstract
The utility model relates to a 3*3-structure hydraulic rubber pipe woven by high-pressure steel wires. The 3*3-structure hydraulic rubber pipe woven by the high-pressure steel wires is mainly applied to hydraulic assembly pipe systems of engineering machinery, coal mine machinery and the like. The 3*3-structure hydraulic rubber pipe woven by the high-pressure steel wires consists of a tubular rubber pipe, an inner rubber sealing layer, a steel-wire-weaving reinforcing layer and an outer rubber protecting layer, wherein the inner rubber sealing layer, the steel-wire-weaving reinforcing layer, a middle rubber protecting layer, the steel-wire-weaving reinforcing layer and the outer rubber protecting layer are sequentially arranged outside the tubular rubber pipe. The 3*3-structure hydraulic rubber pipe woven by the high-pressure steel wires adopts a 3*3 structure; and compared with a 1*1 structure, 66 percent of weaving junctions can be reduced; the pulse performance of the 3*3-structure hydraulic rubber pipe woven by the high-pressure steel wires can be improved by a great leap, the pulse resistance index can be higher to more than twice of the index stated by a GBT3683-1992 state standard and more than twice of the index stated by an ISO international standard, the warping strength index can be improved by 50 percent, and the bending radius can be reduced by 30 percent, so that conditions are provided for upgrade and update of the product quality in the future.
Description
One, technical field
The utility model relates to a kind of high pressure braided steel wire hydraulic pressure 3x3 structure sebific duct, and it is mainly used in hydraulic pressure assembly guard systems such as engineering machinery, coal mine machinery.
Two, background technique
Existing conventional high-tension wire braid hydraulic hose; Generally adopt 1x1 structure, 2x2 structure, though simple in structure, easily manufactured. because structural inadequate natural endowment; Anti-pulse poor performance, flexible resistance are not enough, bending radius is big; Have a strong impact on reliability, the stability of high pressure braided steel wire hydraulic pressure glue, working life is short, and the maintain and replace frequency is many. have a strong impact on manufacturing efficiency and safety in production such as engineering machinery, coal mine machinery.
Three, the content of model utility
The purpose of the utility model is to the deficiency of existing high pressure wire braid hydraulic hose, and a kind of high pressure braided steel wire hydraulic pressure 3x3 structure sebific duct is provided.
The purpose of the utility model realizes like this: it comprises: tubulose sebific duct, interior glue sealing layer, braided steel wire enhancement layer, outer compound protective layer are formed, glue sealing layer in it is disposed with outside the tubulose sebific duct, braided steel wire enhancement layer, middle compound protective layer, braided steel wire enhancement layer and outside compound protective layer; Described braided steel wire enhancement layer is the enhancement layer that is formed by certain pattern braiding by steel wire.
The utility model is carried out the 3x3 structure, can reduce 66 percent braiding tie up point, braiding tie up point than 1x1 structure; Be the inadequate natural endowment of high pressure wire braid hydraulic hose, the tie up point is many more, damages more easily; So, we can say what of braiding tie up point directly determining reliability, the stability of high pressure wire braid hydraulic hose; Also determining to press the working life of wire braid hydraulic hose
The utility model provides a kind of high pressure braided steel wire hydraulic pressure 3x3 structure sebific duct; It can have great-leap-forward to improve the pulse performance; Anti-pulse feature index can reach more than 2 times of GBT3683-1992 GB set quota; Also reached more than 2 times of ISO international standard set quota, the flexible resistance index can improve 50 percent, and bending radius can dwindle 30 percent.
Four, description of drawings
Accompanying drawing 1 is half sectional view of the utility model high pressure braided steel wire hydraulic pressure 3x3 structure sebific duct.
Accompanying drawing 2 is the sectional view of the utility model high pressure braided steel wire hydraulic pressure 3x3 structure sebific duct.
Wherein: compound protective layer, the outer compound protective layer of 5----among 1---tubulose sebific duct, the interior glue sealing layer of 2----, the 3----braided steel wire enhancement layer 4---.
Five, embodiment
Come the utility model done below in conjunction with accompanying drawing and embodiment and describe in further detail:
With reference to accompanying drawing; The utility model high pressure braided steel wire hydraulic pressure 3x3 structure sebific duct; It comprises: tubulose sebific duct 1, interior glue sealing layer 2, braided steel wire enhancement layer 3, outer compound protective layer 5 formed, glue sealing layer 2 in outside tubulose sebific duct 1, being disposed with, braided steel wire enhancement layer 3, middle compound protective layer 4, braided steel wire enhancement layer 3 and outside compound protective layer 5; For strengthening the intensity of braiding, braided steel wire enhancement layer 3 is the enhancement layers that formed by certain pattern braiding by steel wire.The glue sealing layer is 669 oil resistant rubbers in described, and middle compound protective layer is 665 adhesive glues, and outer compound protective layer is 575 oil resistants and wait glue.
