A self-radiating hydraulic pump station shock-absorbing and sound-insulating cover

Abstract

A self-heat-radiation vibration-absorption acoustic enclosure of a hydraulic pump station is suitable for being used on the mobile hydraulic pump station and comprises a supporting structure, a hydraulic pump and a heat-radiation structure. A vibration-absorption sound-insulation structure is composed of a bottom surface sound-insulation wall, lateral sound-insulation walls and a top surface sound-insulation wall and installed on an external vibration-insulation pad on a supporting frame, an internal vibration-insulation pad is arranged on the bottom surface sound-insulation wall inside the acoustic enclosure, and an electric hydraulic pump is arranged on the vibration-insulation pad. A fairing is arranged outside a motor, heat radiation fins are arranged at the back of the motor and are oil cooling heat radiation fins, cooling liquid is outlet oil liquid of the hydraulic pump, passes through the heat radiation fins to take out heat, and provides high-pressure oil liquid for an external hydraulic loop. The self-heat-radiation vibration-absorption acoustic enclosure can reduce vibration of equipment, is good in sound-insulation effect, can effectively control leakage of noise, reduces influences of noise on the environment, and is good in heat radiation effect, small in vibration, simple in structure and convenient to maintain.

Description

technical field [0001] The invention relates to a sound-insulating cover, which is especially suitable for a shock-absorbing and sound-insulating cover of a self-radiating hydraulic pump station used on a mobile hydraulic pump station. Background technique [0002] The hydraulic system laboratory is mainly used for teaching and scientific research on the structure and principle of the hydraulic system, inspection and adjustment, and fault research. The hydraulic pump station is an important part of the laboratory, which mainly provides the laboratory with the hydraulic energy required for various tests. However, when the hydraulic pump is working, it is noisy, especially when the working pressure is high, it often emits a harsh scream. This kind of noise seriously interferes with the teacher's explanation and demonstration, distracts the students' attention, affects the teaching effect, and pollutes the surrounding environment at the same time. In addition, in noise monito...

AI Technical Summary

Problems solved by technology

This technology uses a fully enclosed sound insulation cover to isolate the noise radiation of the hydraulic pump, but it also brings ventilation and heat dissipation problems. The current method is to introduce a muffler to solve the ventilation and heat dissipation problems, but the result is low frequency. Noise control effect is not good

In recent years, there is also an active noise control system used in the noise control of hydraulic pumps, but the application of this system is not yet mature, and the cost of use is relatively high
