Mute power supply

Abstract

The invention discloses a mute power supply. The mute power supply comprises a base and a diesel generating set, wherein the upper end of the base is fixedly connected with a mounting frame, the innerside of the mounting frame is provided with a mounting plate, the diesel generating set is mounted on the mounting plate, the diesel generating set is connected with a fuel inlet pipe, a discharge outlet pipe and a wiring pipe, the fuel inlet pipe, the discharge outlet pipe and the wiring pipe penetrate through the lower portion of the mounting plate, a vibration reduction mechanism connected with the mounting plate is arranged on the base, an inner shell and an outer shell are fixedly mounted at the upper end of the mounting plate, the inner shell covers the outer side of the diesel generator set, the outer shell covers the outer side of the inner shell, and a partition plate fixedly connected with the outer shell is fixedly connected to the outer wall of the upper portion of the inner shell. According to the mute power supply, by arranging the vibration reduction mechanism, effective vibration reduction and silencing effects are achieved, meanwhile, noise leakage of air intake and exhaust is greatly reduced, effective sound absorption and noise reduction can be achieved, and the ultra-silence working effect is achieved.

Description

technical field [0001] The invention relates to the technical field of silent power supplies, in particular to a silent power supply. Background technique [0002] The silent power supply is mainly used in the emergency backup power system. After the power system loses the power supply of the off-site power grid, it provides power to the designated equipment to ensure its normal operation. The diesel generator set is mainly used as the power generation unit. [0003] However, when the ordinary silent diesel generator set is running, it usually produces a lot of noise. The current silent power supply is installed on the outside of the diesel generator set with an ordinary silent box cover for noise reduction and sound absorption. , Exhaust fan, directly connected to the outside for ventilation and heat dissipation, resulting in serious noise leakage from the air intake and exhaust outlets, and the direct transmission of vibration when the diesel generator set is working, whic...

[0003] However, when the ordinary silent diesel generator set is running, it usually produces a lot of noise. The current silent power supply is installed on the outside of the diesel generator set with an ordinary silent box cover for noise reduction and sound absorption. , Exhaust fan, directly connected to the outside for ventilation and heat dissipation, resulting in serious noise leakage from the air intake and exhaust outlets, and the direct transmission of vibration when the diesel generator set is working, which also leads to greater noise and vibration. Therefore, a silent power supply is now designed. solve the above problems
