AI Technical Summary
Existing electronic oil pumps lack effective noise reduction measures during use, resulting in serious noise problems, especially at 4000rpm, generating 70-80dB wideband noise, with high-frequency noise in the 2000-4000Hz range accounting for more than 40%.
An electronic oil pump noise reduction structure is adopted, which includes a combination design of mounting plate, decorative panel, sound-absorbing felt and buffer pad. The sound-absorbing felt absorbs noise through honeycomb sound-absorbing holes, the buffer pad reduces vibration at the connection, the outer protective plate enhances heat dissipation, and the buffer pad contacts the mounting plate to reduce rigid connections.
It effectively absorbs noise, reduces vibration at the connection point, improves the safety and noise reduction effect of the working environment, and enhances the overall noise reduction performance of the electronic oil pump.
