Abstract
The invention relates to a water-ring vacuum pump exhaust pipe noise eliminating device which is characterized by comprising an air inlet pipe (3) and an exhaust pipe (5), wherein the exhaust pipe (5) is located in the air inlet pipe (3); the upper end of the exhaust pipe (5) is fixedly connected with a water-ring vacuum pump exhaust pipe (7), and the lower end of the exhaust pipe (5) is fixedly connected with the lower end of the exhaust pipe (5) through an annular baffle (6); the upper end of the exhaust pipe (5) is of a sealed structure, and the lower end of the exhaust pipe (5) is of an opened structure located below the annular baffle (6); a plurality of exhaust ports are uniformly distributed in the surface of the exhaust pipe (5); a breathable diaphragm (4) covers the plurality of exhaust ports. According to the device, the vacuum pump exhaust pipe is provided with a silencing device capable of completely eliminating noise generated at the vacuum pump exhaust pipe under the condition that the normal work of a vacuum pump is not affected, so that the silencing device has environment protection and noise reduction effects.
Description
Technical field
The present invention relates to a kind of Nash hytor outlet pipe noise absorber.
Background technique
Water ring vaccum pump (abbreviation water ring pump) is a kind of coarse vacuum pump, and its obtainable limiting vacuum is 2000-4000Pa, and series connection vacuum pump can reach 270 ~ 670Pa.Water ring pump also can be used as compressor, is called liquid piston compressor, is the compressor that belongs to low pressure, and its pressure range is 1-2 × 105Pa manometer pressure.
But in use there is following technological deficiency in water ring vaccum pump: in vacuum pump working procedure, outlet pipe is subject to gas impact shock and produces the noise that sound level is higher, near working environment contaminated equipment.
Summary of the invention
The present invention has designed a kind of Nash hytor outlet pipe noise absorber, and the technical problem of its solution is in vacuum pump working procedure, and outlet pipe is subject to gas impact shock and produces the noise that sound level is higher, near working environment contaminated equipment.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of Nash hytor outlet pipe noise absorber, it is characterized in that: comprise suction tude (3) and outlet pipe (5), outlet pipe (5) is arranged in suction tude (3), outlet pipe (5) upper end is fixedly connected with Nash hytor outlet pipe (7), outlet pipe (5) lower end is fixedly connected with outlet pipe (5) lower end by ring baffle (6), outlet pipe (5) upper end is sealing configuration, outlet pipe (5) lower end is hatch frame, hatch frame is positioned at ring baffle (6) below, on outlet pipe (5) surface, be uniformly distributed multiple exhaust ports, gas permeability barrier film covers (4) on multiple exhaust ports.
Further, outlet pipe (5) upper end forms sealing configuration by connecting a blind plate (2).
Further, suction tude (3) lower end has screw hole, and bolt coordinates rear support ring baffle (6) with screw hole.
Further, suction tude (3) upper end and Nash hytor outlet pipe (7) outlet end all merit have screw hole, and suction tude (3) is fixed and is connected by bolt (1) with Nash hytor outlet pipe (7).
This Nash hytor outlet pipe noise absorber has following beneficial effect:
(1) the present invention installs a silencer on vacuum pump outlet pipe, makes it in the situation that not affecting the normal work of vacuum pump, and the thorn ear noise at vacuum pump outlet pipe place is eliminated completely, plays the effect of environmental protection noise reduction.
(2) the present invention have advantages of that simple in structure, stable performance, fabrication and installation are convenient, economic environmental protection and effective noise reduction, for staff creates quiet comfortable working environment.

The making method of Nash hytor outlet pipe noise absorber of the present invention is as follows:
(1) at 5 dozens of exhaust ports of outlet pipe, it is uniformly distributed;
(2) suction tude 3 symmetrical position tap holes, two ends;
(3) gas permeability barrier film 4 is packaged on the outlet pipe 5 having punched;
(4) outlet pipe 5 is packed in suction tude 3, fixing with bolt and ring baffle 6, form air inlet and two seal chambers of exhaust;
(5) utilize fastening piece that silencer is arranged on vacuum pump outlet pipe 7.
Being connected of silencer and vacuum pump outlet pipe should be solid and reliable and have a good tightness.
By reference to the accompanying drawings the present invention has been carried out to exemplary description above; obvious realization of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present invention and technological scheme to carry out; or without improving, design of the present invention and technological scheme are directly applied to other occasion, all in protection scope of the present invention.
