Detailed Description

The invention is composed of a cooling layer 1, an outer rubber layer 2, a reinforcing layer 3, an intermediate rubber layer 4, a reinforcing layer 5 and an inner rubber layer 6.

The innermost layer of the invention is shown as an inner rubber layer 6, and hydraulic oil passes through the middle of the inner rubber layer 6. The inner rubber layer 6 is positioned at the innermost layer of the high-pressure rubber pipe, is a functional structure for sealing and bearing the high-pressure rubber pipe, and protects the steel wires of the bearing enhancement layer 3 and the reinforcement layer 5 from being soaked by hydraulic oil.

The figure shows that outside the inner rubber layer 6, a reinforcing layer 5, an intermediate rubber layer 4 and a reinforcing layer 3 are coated in sequence. The reinforcing layer 5 and the reinforcing layer 3 are respectively steel wires with a weaving or winding structure, and the weaving steel wires are generally formed by cross weaving of fine steel wires with the diameter of 0.3-0.5 mm; the winding steel wire is generally formed by winding 0.4-0.7 mm thin steel wires in a single direction. The enhancement layer and the reinforcing layer can ensure that the high-pressure rubber pipe has enough strength, and simultaneously, the bending flexibility of the high-pressure rubber pipe is not influenced. The middle rubber layer 4 is between the reinforcing layer 3 and the reinforcing layer 5, and serves to bind and fix the steel wires of the reinforcing layer 3 and the reinforcing layer 4, increasing stability and wear resistance.

The figure shows that outside the reinforcing layer 3 is an outer rubber layer 2, and the outer rubber layer 2 plays a role of protecting the high-pressure rubber hose from external factors.

The figure shows that outside the outer rubber layer 2 is a cooling layer 1, which is the most important structure of the invention. The cooling layer 1 is composed of a stainless steel corrugated pipe 9 and cooling water 10, the stainless steel corrugated pipe 9 is sleeved outside the outer rubber layer 2, a gap is formed between the inner wall of the stainless steel corrugated pipe and the outer wall of the outer rubber layer, the cooling water 10 is filled in the gap, and a water inlet 7 and a water outlet 8 are respectively arranged at two ends of the pipe wall of the stainless steel corrugated pipe 9. Cooling water 10 enters the space between the stainless steel corrugated pipe 9 and the outer rubber layer 2 from the water inlet 7 at one end of the stainless steel corrugated pipe 9 and is discharged from the water outlet 9 at the other end of the stainless steel corrugated pipe 9, the cooling water 10 flows through the surface of the outer rubber layer 2 to absorb the heat on the surface of the outer rubber layer 2, and the discharged cooling water 10 can take away the absorbed heat to achieve the purpose of effectively reducing the temperature of the outer rubber layer 2.

The stainless steel corrugated pipe 9 is formed by adopting a seamless pipe or a welded pipe with the thickness of 0.2-1.5mm, the stainless steel corrugated pipe 9 is formed by sequentially arranging a plurality of closed circular ring-shaped tubular shells, and the circular ring-shaped tubular shells are connected into a whole by circular ring ripples in series. The corrugated structure of the stainless steel corrugated pipe 9 has the advantages of fast heat conduction, good elasticity, easy bending and the like, and plays a role in conveying cooling water on the one hand and can fast dissipate heat on the other hand to cool the high-pressure rubber pipe on the condition of not influencing the bending performance of the high-pressure rubber pipe.
