Abstract
The utility model relates to a hose for wind-powered electricity generation cooling system belongs to fluid transport technical field. The hose is composed of a flexible section and joints positioned at two end parts of the flexible section; the flexible section is composed of an inner metal corrugated hose, a middle metal mesh sleeve and an outer non-metal coating layer which are coated in layers, a metal ring which is sleeved on the outer surface of the metal mesh sleeve and used for fixing the metal mesh sleeve is arranged at the position of a connecting part of the flexible section and the joint, the metal mesh sleeve completely covers the outer surface of the metal corrugated hose, and the non-metal coating layer is in a shrinkage state and tightly covers the outer surfaces of the metal mesh sleeve, the metal ring and the connecting part. Because the three-layer stack parcel layer structure of flexible section has increased the protection to corrugated metal tubing, and outer non-metallic coating layer is the surface that the contraction state closely covered at metal net cover, becket and connecting portion especially, can make corrugated metal tubing avoid receiving the corruption of offshore wind power generation in salt fog and sunshine environment well, improves corrugated metal tubing's life.
Description
Technical Field
The utility model relates to a metal collapsible tube that wind-powered electricity generation cooling system used belongs to fluid transport technical field.
Background
With the continuous growth of new energy power generation markets, wind power generation gradually develops from onshore power generation to offshore power generation, the single-machine capacity of a generator set is continuously developed and promoted from a kW level to a MW level, and the cooling mode of a converter, a generator and an inverter of the generator set is gradually changed from traditional air cooling to water cooling. The water cooling system pipeline comprises a steel pipe and a pressure-resistant hose, wherein the pressure-resistant hose is generally selected to be used for compensating pipeline installation deviation and absorbing vibration, and the electric cooling system mostly uses a rubber hose at the early stage, is easy to age and leak and is gradually replaced by a metal hose. The metal hose has the advantages of light weight, good flexibility, high temperature resistance and the like, and the coastal and offshore wind power generation cooling system also requires that the metal hose has the capability of resisting corrosion in salt spray and sunshine environments for a long time. However, the metal corrugated pipe in the metal hose has a thin wall, so that the fine scratches or pits and the like damage the dense passive film on the surface of the stainless steel in the production or installation and use process, and after the chlorine ions in the salt spray contact the fine scratches or pits, the chlorine ions are easy to accumulate near the scratches or pits, and the corrosion is accelerated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that, the metal collapsible tube that makes wind-powered electricity generation cooling system use possesses the ability of steady operation in the high salt fog high sunshine environment of coastal long-term.
The utility model discloses a solve the technical scheme that above-mentioned technical problem provided and be: a hose for a wind power cooling system comprises a flexible section and joints positioned at two end parts of the flexible section; the flexible section is composed of an inner metal corrugated hose, a middle metal net sleeve and an outer non-metal coating layer which are coated in layers, a metal ring which is sleeved on the outer surface of the metal net sleeve and used for fixing the metal net sleeve is arranged at the position of a connecting part of the flexible section and the joint, the metal net sleeve completely covers the outer surface of the metal corrugated hose, and the non-metal coating layer is in a shrinkage state and tightly covers the outer surfaces of the metal net sleeve, the metal ring and the connecting part.
Further, the non-metal coating layer is made of flame-retardant polyolefin material. The joint is a stainless steel hoop quick joint or a high-pressure flange and is used for being connected with the pipeline of the wind power cooling system in a sealing mode. The metal ring is buckled and pressed at the end part of the metal net sleeve and is used for pressing the metal net sleeve on the outer surface of the metal corrugated hose.
The utility model has the advantages that: because the flexible section (three-layer stack parcel layer structure) of the three-layer stack parcel of inlayer corrugated metal hose, intermediate level metal mesh cover and outer non-metal coating layer has been designed, increased the protection to corrugated metal hose, especially outer non-metal coating layer is the surface that the contraction state closely covered at metal mesh cover, becket and connecting portion, can make corrugated metal hose avoid receiving the corruption of offshore wind power generation at salt fog and sunshine environment well, improve corrugated metal hose's life. In addition, the flame retardant, ultraviolet resistant and cold and hot alternating resistant capability is also provided.
Drawings
The metal hose for the wind power cooling system of the present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic sectional structure view of a metal hose for a wind power cooling system according to an embodiment of the present invention.
Detailed Description
Examples
The metal hose for the wind power cooling system of the embodiment is composed of a flexible section 1 and joints 2 positioned at two end parts of the flexible section 1 as shown in fig. 1; wherein one end joint 2 adopts the clamp quick-operation joint, and the other end joint 2 adopts high-pressure flange. The flexible section 1 is composed of an inner metal corrugated hose 3, a middle metal mesh sleeve 4 and an outer non-metal coating layer 5 which are coated in layers, a metal ring 6 which is sleeved on the outer surface of the metal mesh sleeve 4 and used for fixing the metal mesh sleeve 4 is arranged at the position of a connecting part of the flexible section 1 and the joint 2, the metal mesh sleeve 4 completely covers the outer surface of the metal corrugated hose 3, and the non-metal coating layer 5 is in a shrinkage state and tightly covers the outer surfaces of the metal mesh sleeve 4, the metal ring 6 and the connecting part of the flexible section 1 and the joint 2. The joint 2 is generally made of a metal material.
The corrugated metal hose 3 is made of stainless steel material; the non-metal coating layer 5 is made of flame-retardant polyolefin material; the metal ring 6 is made of stainless steel material, and the metal ring 6 is buckled and pressed at the end part of the metal net sleeve 4 to ensure that the metal net sleeve 4 is tightly pressed on the outer surface of the metal corrugated hose 3 without loosening.
During the use, through insert wind-powered electricity generation cooling system with the joint 2 at metal collapsible tube both ends on arbitrary section pipeline can. The anti-corrosion metal corrugated pipe has the effects of pipe connection, shock absorption and installation displacement compensation, meanwhile, the nonmetal coating layer is utilized to prevent salt fog from corroding the metal corrugated pipe, and the anti-corrosion metal corrugated pipe has the capabilities of flame retardance, ultraviolet resistance and cold and hot alternation resistance, and the service life of the metal hose in a high-sunshine high-salt fog environment is effectively prolonged.
The utility model discloses do not confine each above-mentioned embodiment to, all adopt the technical scheme who equates to replace and form, all fall in the utility model discloses the scope of protection that requires.
