Abstract
The utility model relates to a lower air inlet type midget reciprocating piston type air compressor, which belongs to mechanical equipment. The lower air inlet type midget reciprocating piston type air compressor comprises an aspirator filtering silencer (1) installed at the upper part of a machine body and positioned close to the air inlet of a piston cylinder. The lower air inlet type midget reciprocating piston type air compressor is characterized in that the air inlet of the aspirator filtering silencer (1) is connected with an aspirator buffering noise reducing pipe (4) positioned at the lower part of the machine body through an air inlet pipe (2), and the aspirator buffering noise reducing pipe (4) is connected with an aspirator filtering silencer (3). The lower air inlet type midget reciprocating piston type air compressor successfully solves the problem that the noise is loud when a plurality of midget reciprocating piston type air compressors are connected in series, thereby having the advantages that both the noise and the exhaust temperature are reduced.
Description
Technical field
The utility model relates to a kind of machinery, especially a kind of mini air compressor, specifically a kind of small-sized reciprocating-piston air compressor of air intake type down.
Background technique
Small-sized reciprocating-piston air compressor is a kind of common aerodynamic force equipment, especially is widely used at food and packaging industry.Fast development along with food industry in recent years, small-sized reciprocating-piston air compressor with its combination flexibly, peak regulating function is obvious, the power savings remarkable advantages is replacing those large air compressors gradually, but because the noise of light duty compressor is very big, cause and use small-sized reciprocating-piston air compressor group's workshop overall noise to be easy to exceed standard, easily health is threatened.The claimant finds through a large amount of investigations, the intakeport of existing small-sized reciprocating-piston air compressor all is positioned at body upper and noise is very big, and, cause delivery temperature higher relatively because the air of being inhaled is hot air, influenced the performance of unit performance.
Summary of the invention
The purpose of this utility model is that the noise that exists at existing small-sized reciprocating-piston air compressor is big, influences the problem of efficient performance, designs a kind of small-sized reciprocating-piston air compressor of air intake type down.
The technical solution of the utility model is:
A kind of small-sized reciprocating-piston air compressor of air intake type down, comprise near the air-breathing filtering silencer 1 piston cylinder suction port of being positioned at that is installed in body upper, the suction port that it is characterized in that described air-breathing filtering silencer 1 links to each other with the air inlet buffering noise reduction pipe 4 that is positioned at underpart by suction tude 2, and described air inlet buffering noise reduction pipe 4 is connected with air-breathing filtering silencer 3.
Described air inlet buffering noise reduction pipe 4 is connected with two or more suction tude 2 and two or more air-breathing filtering silencer 3, to satisfy the needs of the small-sized reciprocating-piston air compressor polyphone use more than two or two.
The beneficial effects of the utility model:
The utility model moves down by the suction port with small-sized reciprocating-piston air compressor, and by a kind of buffering noise reduction pipe air feed, when reducing intake temperature, greatly reduces air suction and noise, can make noise descend about 50%, and noise reduction is fairly obvious.
Because the heat that unit produces is on top, and hot air is to rising, and the utility model adopts and makes inhalation temperature can reduce about 5-10 degree centigrade from the air-breathing mode in bottom, therefore can make the also corresponding reduction of delivery temperature of unit, the performance of unit is improved, and energy consumption reduces.
The utility model both had been applicable to that unit used, but many polyphone group of planes that are particularly useful for the food package industry use, for using the small-sized air compressor group to replace large scale computer that guarantee is provided, the noise of whole group of planes work can be lower than the noise of separate unit large scale computer, improve its competitive ability, helped giving full play to flexible and changeable, the energy-saving advantages of minicomputer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of small-sized reciprocating-piston air compressor of air intake type down, comprise near the air-breathing filtering silencer 1 piston cylinder suction port of being positioned at that is installed in body upper, the outlet side of air-breathing filtering silencer 1 communicates with the suction port of piston cylinder, the suction port of air-breathing filtering silencer 1 links to each other with the air inlet buffering noise reduction pipe 4 that is positioned at underpart by suction tude 2, and described air inlet buffering noise reduction pipe 4 is connected with air-breathing filtering silencer 3.The suction tude 2 that connects on the air inlet buffering noise reduction pipe 4 when specifically implementing and the quantity of air-breathing filtering silencer 3 equate with the quantity of the small-sized reciprocating-piston air compressor of polyphone use simultaneously, Figure 1 shows that two small-sized reciprocating-piston air compressor polyphones use, so air inlet buffering noise reduction pipe 4 is connected with two suction tude 2 and two air-breathing filtering silencers 3.
The utility model does not relate to part to be realized as prior aries that maybe can adopt all same as the prior art such as the concrete structure of compressor, control system.
