Abstract
The utility model relates to a noise silencer for a water ring type vacuum pump, which is characterized in that the noise silencer comprises a silencer body, a spring sleeve, a spring and a steel ball, wherein the front end of the silencer body is provided with an air inlet passage, and the back end is provided with a cavity body; the back end of the spring sleeve is provided with an air inlet passage, and the front end is provided with a hollow cavity; the front end of the spring sleeve forms internal thread connection with the cavity body on the back end of the silencer body; the external of the spring sleeve is provided with external thread and is sheathed with a tightening nut; the steel ball is arranged in the hollow cavity on the front end of the spring sleeve; the spring is additionally arranged between the steel ball and the air inlet passage on the front end of the silencer body. The utility model is installed in a proper position near an air inlet of the water ring type vacuum pump, when the steel ball clogs the air inlet passage of the spring sleeve, the state of the water ring vacuum pump is the same with that of the water ring vacuum pump which is not additionally provided with the silencer; when the steel ball opens the air inlet passage of the spring pocket, a small amount of air enters the vacuum pump, preventing the vacuum pump from reaching limit pressure under the conditions that the vacuum degree and the maximum air pumping amount are not influenced. Thus, the phenomenon that the vacuum pump generates non-mechanical motion noise under the limit pressure is avoided.
Description
Technical field
The utility model belongs to the device of the noise of eliminating Nash hytor on-mechanical motion generation.
Background technique
The mechanical pump vacuum unit of present most Nash hytor and composition thereof in vacuum, produces on-mechanical motion noise when reaching the ultimate pressure of this equipment when bleeding, cause the noise pollution of working environment.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Nash hytor silencer, avoids vacuum pump to produce on-mechanical motion noise under ultimate pressure.
The utility model Nash hytor silencer, it is characterized in that comprising body, spring housing, spring, steel ball, the body front end is provided with gas-entered passageway, and the rear end is a cavity, and the spring housing rear end is provided with gas-entered passageway, front end is a cavity, the spring housing front end is that internal thread is connected with body rear end cavity, and spring housing is provided with outside thread outward, is with the degree of tightness nut, steel ball places the cavity of spring housing front end, is added with spring between the gas-entered passageway of steel ball and body front end.
The utility model is installed in a slightly side of lower position of Nash hytor suction port by the body front end, and the gas-entered passageway of spring housing rear end communicates with the external world, and when gas-entered passageway that the steel ball spring blocking overlaps, not add this silencing apparatus state the same with Nash hytor; When steel ball opens wide the gas-entered passageway of spring housing, in vacuum pump, advance a spot of air, make vacuum pump under the situation that does not influence degree of vacuum and maximum rate of air sucked in required, avoid the vacuum pump pressure that reaches capacity, thereby avoid vacuum pump under ultimate pressure, to produce on-mechanical motion noise.
Using method is:
1, the outer degree of tightness nut of trip spring cover;
2, screw or unscrew spring housing, and drive length of spring compressed or loosen steel ball, make the gas-entered passageway or the unlimited gas-entered passageway of steel ball spring blocking cover.The gas-entered passageway that opens wide spring housing makes Nash hytor or unit not reach the ultimate pressure state, avoids the generation of on-mechanical motion noise;
3, adjusting finishes, and the degree of tightness nut is compressed, fixedly the adjustment state of silencing apparatus.
Advantage of the present utility model:
Under the situation that does not influence vacuum pump degree of vacuum and rate of air sucked in required, avoid the vacuum pump pressure that reaches capacity, thereby avoid vacuum pump under ultimate pressure, to produce on-mechanical motion noise.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 spring housing, 2 degree of tightness nuts, 3 springs, 4 steel balls, 5 bodies, 6,7 gas-entered passageways, 8 outside threads
Embodiment
As Fig. 1, body 5 front ends are provided with gas-entered passageway 6, and the rear end is a hollow cavity, and spring housing 1 rear end is provided with gas-entered passageway 7 and communicates with ambient air, front end is a cavity, steel ball 4 places this cavity, is added with spring 3 between the gas-entered passageway 6 of steel ball 4 and body 5 front ends, and spring housing 1 is that internal thread is connected with body 5 rear end cavitys, the spring housing 1 outer outside thread that is provided with, be with degree of tightness nut 2, body 5 front ends have outside thread 8, and convenience is connected with vacuum pump suction tude one side.
Using method is:
1, the degree of tightness nut 2 outside the trip spring cover 1;
2, screw or unscrew spring housing 1, and drive spring 3 compressions or loosen steel ball 4, make steel ball 4 stop up gas-entered passageway 7 or unlimited gas-entered passageway 7; By the degree that compresses of 1 pair of spring 3 of Regulation spring cover, can regulate the gap between steel ball and the gas-entered passageway 7, thereby the adjusting air inflow under the situation that does not influence vacuum pump degree of vacuum and rate of air sucked in required, is avoided the vacuum pump pressure that reaches capacity.
3, adjusting finishes, and degree of tightness nut 2 is compressed, fixedly the adjustment state of silencing apparatus.
