3results about How to "Solving resonance problems" patented technology

This utility model relates to the field of compressor technology, specifically disclosing a plastic coil integrated with the intake and exhaust chambers. It includes an integrated cylinder head, with an intake silencer chamber upper cover, an exhaust silencer chamber upper cover, an intake silencer chamber lower cover, and an exhaust silencer chamber lower cover integrally formed at the bottom end of the cylinder head. The bottom end of the exhaust silencer chamber lower cover is connected to and installed with a plastic coil. A Bundy tube is fitted onto the end of the plastic coil, and a compressor exhaust pipe is welded to the end of the Bundy tube opposite to the plastic coil. The intake and exhaust silencers and cylinder head of this application are integral injection molded parts, reducing installation steps and connecting parts. The plastic coil is made of common materials such as polypropylene, replacing the Bundy tube, and its inherent frequency avoids the power supply frequency commonly used in variable frequency products, thus solving the resonance problem. A 30mm Bundy tube connects the plastic exhaust chamber and the compressor exhaust pipe, solving the welding problem, and a sol-gel tank is provided at the connection point for heat fusion, preventing the coil from falling off.

The low-noise compressor shell comprises a shell body, a plurality of craters are arranged on the surface of the shell body, and the craters enable the surface of the shell body to form a honeycomb pitted surface. The surface of the compressor shell is treated to form craters, so that the surface of the shell presents a honeycomb pitted surface effect, the reflection path of sound waves is increased, the penetration of noise is reduced, the inherent frequency of the whole machine is improved and the resonance problem can be effectively avoided through the characteristic that the surface of the shell is uneven.

The utility model provides a kind of internal combustion engine slide valve type gas distribution structure, including lower valve body, slide valve and upper valve body, slide valve is located in upper valve body, lower valve body intermediate, transmission rod is equipped between upper valve body and slide valve, transmission rod one end is equipped with sprocket, slide valve is integrally embedded in lower valve body upper end surface, gas distribution port is opened in slide valve, lower valve body is opened in and exhaust hole one gas inlet hole one, upper valve body is opened in and exhaust hole two gas inlet hole two, exhaust hole two corresponding position with gas inlet hole one, gas inlet hole two of the utility model have Advantage: through the combination structure of lower valve body, slide valve, upper valve body and transmission rod, avoid traditional valve type gas distribution structure spring resonance problem, improve gas distribution timing precision, gas distribution phase flexible adjustment, simplify overall structure, improve gas flow efficiency simultaneously, it is favorable for fuel full combustion and the improvement of internal combustion engine power performance.
