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 belonging to low pressure, and its pressure range is 1-2 × 105Pa manometer pressure.
But water ring vaccum pump in use exists following technological deficiency: in vacuum pump working procedure, outlet pipe is subject to gas impact shock and produces the higher noise of sound level, the working environment near contaminated equipment.
Summary of the invention
The present invention devises a kind of Nash hytor outlet pipe noise absorber, and its technical problem solved is in vacuum pump working procedure, and outlet pipe is subject to gas impact shock and produces the higher noise of sound level, the working environment near contaminated equipment.
In order to solve the technical problem of above-mentioned existence, present invention employs 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, multiple exhaust port is uniformly distributed on the surface at outlet pipe (5), breathable membrane covers (4) on multiple exhaust port.
Further, outlet pipe (5) upper end forms sealing configuration by connection one 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) and Nash hytor outlet pipe (7) are fixed by bolt (1) and are connected.
This Nash hytor outlet pipe noise absorber has following beneficial effect:
(1) the present invention installs a silencer on vacuum pump discharges pipe, makes it when not affecting vacuum pump and normally working, is eliminated completely by the audible noise at vacuum pump discharges pipe place, play the effect of environmental protection noise reduction.
(2) the present invention has that structure is simple, stable performance, fabrication and installation are convenient, the advantage of economic environmental protection and effective noise reduction, for staff creates quiet comfortable working environment.

Embodiment
Below in conjunction with Fig. 1 and Fig. 2, the present invention will be further described:
As shown in Figure 1, a kind of Nash hytor outlet pipe noise absorber, 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 below ring baffle 6, be uniformly distributed multiple exhaust port on the surface at outlet pipe 5, breathable membrane covers 4 on multiple exhaust port.
Outlet pipe 5 upper end forms sealing configuration by connection one blind plate 2.Suction tude 3 lower end has screw hole, and bolt coordinates rear support ring baffle 6 with screw hole.Suction tude 3 upper end and Nash hytor outlet pipe 7 outlet end all merit have screw hole, and suction tude 3 and Nash hytor outlet pipe 7 are fixed by bolt 1 and are connected.
The making method of Nash hytor outlet pipe noise absorber of the present invention is as follows:
(1) at outlet pipe 5 dozens of exhaust ports, it is made to be uniformly distributed;
(2) suction tude 3 two ends symmetrical position tap hole;
(3) breathable membrane 4 is packaged on the outlet pipe 5 punched;
(4) outlet pipe 5 is loaded in suction tude 3, fix with bolt and ring baffle 6, form air inlet and exhaust two seal chambers;
(5) fastening piece is utilized to be arranged on vacuum pump discharges pipe 7 by silencer.
The connection of silencer and vacuum pump discharges pipe is answered solid and reliable and has good tightness.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technological scheme is carried out; or design of the present invention and technological scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
