Abstract
The utility model belongs to a damping and noise reduction device utilized in the pump, which mainly includes two flanges, a corrugated pipe, screw rods, and the parts installed on the two ends of the screw rod, including a cone damping combined pad, a concave convex washer, a retaining tablets, and a screw. The corrugated pipe referred is made of the layered materials. The bottom layer (inner layer) and the surface (outer layer) of the corrugated pipe is made of the corrosion resistance materials, such as stainless steel plate, the interlayer (middle layer) is made of nonmetallic materials, such as glass cloth; The device in the utility model can be installed on the pipe used to transport the fluid, which can effectively reduce the noise transport along the pipe and absorb the vibration generated by the fluid transporting equipment.
Description
The utility model belongs on the engineering vibration and noise reducing device technical field of using on the pipeline that uses pump conveyance fluid or air compressor conveying gas.
At present, the equipment that conveyance fluid uses on engineering as pump, air compressor etc., produces vibration and noise when work, and vibration has bigger influence to the life-span and the working efficiency of equipment, the noise pollution environment, and disturbing residents does not reach the target of civilization work.By entrusting Patent Office the update search of domestic and international patent documentation not to be found the document of being correlated with.Similar technical products is not found in market survey yet.
The purpose of this utility model provide a kind of in the process of conveyance fluid the effective transmission and the vibration and noise reducing device that uses of the vibration that produces of absorption fluids conveying equipment of blocking-up noise on pipeline.
The purpose of this utility model is achieved in that installs the vibration and noise reducing device that the utility model provides on the pipeline of equipment such as pump or air compressor conveyance fluid.The vibration and noise reducing device that the utility model provides, comprise flange plate, bolt, it is characterized in that: the two ends of bellows and flange plate are connected and fixed together, flange plate is provided with screw hole, all there is screw thread at the screw rod two ends, after screw rod and the screw hole assembling, wherein at screw rod one end conical surface vibration damping combination mat are installed successively, concavo-convex packing ring, retaining sheet, nut are installed concavo-convex packing ring, retaining sheet, nut successively at the other end of screw rod.
Described bellows is composited with stratified material, and bottom (internal layer) and surface layer (skin) are made of corrosion resistant metallic material such as corrosion resistant plate, and interlayer (mesosphere) is made of nonmetallic material such as glass fiber cloth.
Assembling 3-6 group screw rod on the described flange plate.
Be evenly equipped with 3-6 bolt hole on the described flange plate.
Pump vibration and noise reducing device of the present utility model, owing to be installed on the pipeline of conveyance fluid, fluid passes through the end thrust of this device bellows generation by the combination mat at screw rod and screw rod two ends, concavo-convex packing ring, retaining sheet, the nut restriction, the amplitude that equipment (coming self-pumping or air compressor) produces is absorbed by cone rubber vibration damping combination mat, during noise process bellows, because bellows is composited by trilaminate material, noise transmission is produced big damping, and level of noise reduces with the increase of the composite pipe number of plies.Because the utility model structure is ingenious, scientific and reasonable, not only durable in use, and effect is remarkable, just can prolong the life-span of equipment behind use the utility model, increase work efficiency, reduce noise, reach the purpose of civilization work.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structure partial generalized section of the present utility model.
Fig. 2 is the structural profile enlarged view of Fig. 1 I part.
Reference character: 1. screw rod, 2. nut, 3. retaining sheet, 4. concavo-convex packing ring, 5. conical surface vibration damping combination mat, 6. flange plate, 7. screw hole, 8. bolt hole, 9. bolt, 10. bellows, 11. bellows internal and external layer (bottom, surface layer), 12. bellows mesospheres (interlayer).
As shown in the figure: the two ends of bellows 10 are fixed on the flange plate 6, bolt hole 8 and screw hole 7 are all arranged on two flange plate 6, all there is screw thread at screw rod 1 two ends, after screw rod 1 is installed in screw hole 7, wherein an end is installed conical surface vibration damping combination mat 5, concavo-convex packing ring 4, retaining sheet 3, nut 2 successively, and the other end is installed concavo-convex packing ring 4, retaining sheet 3, nut 2 successively.Bolt hole 8 usefulness bolts 9 are fixed with the flange plate on the pipeline.
The pump that the utility model provides is installed in vibration and noise reducing device can effectively block transmission and the absorption fluids conveying equipment vibration that produce of noise on pipeline on the pipeline of conveyance fluid.
