Abstract
The utility model relates to a motor casing with a built-in sound absorbing layer, which belongs to a sound absorbing casing, in particular to the motor casing with the built-in sound absorbing layer. In order to solve the problems that the vibration noise of an electric motor of a water injection pump used by an oil field at present is high, particularly, the air noise is as high as 112dB(A), the work environment of the oil field is influenced, and the body and mental health of workers is harmed. The motor casing disclosed by the utility model comprises an outer support casing, two separation plates, the built-in sound absorbing layer and an inner support casing, wherein the outer support casing is sheathed on the inner support casing, a layer of built-in sound absorbing layer is arranged between the outer support casing and the inner support casing, and the two separation plates used for fixing the motor are and vertically arranged in the inner support casing in parallel. The motor casing disclosed by the utility model is arranged outside the electric motor and is used for reducing the noise generated when the electric motor works.
Description
Technical field
The utility model relates to a kind of sound absorption housing, is specifically related to a kind of electric machine casing of built-in absorbent treatment.
Background technology
The water-flooding pump for oil field scope of application is extensive at present, and water injection pump continuous running at full capacity 24 hours every days, what the widely used water injection pump in oil field adopted now is Y series motor, its vibration noise is big, particularly airborne noise is up to 112dB (A), influence the operational environment in oil field, endangered workman's physical and mental health.
The utility model content
The utility model uses the motor vibration noise of water injection pump big in order to solve present oil field, particularly airborne noise is up to 112dB (A), influence the operational environment in oil field, endangered workman's able-bodied problem, and then proposed a kind of electric machine casing of built-in absorbent treatment.
The utility model in order to address the above problem the technical scheme of taking is: the utility model comprises outer support housing and two dividing plates, also comprise built-in absorbent treatment and interior support housing, described outer support housing is sleeved on the interior support housing, the built-in absorbent treatment of one deck is arranged between outer support housing and the interior support housing, and two dividing plates that are used for fixing motor are vertically set in the interior support housing side by side.
The beneficial effects of the utility model are: acoustically effective of the present utility model reaches 20dB (A), can make the airborne noise of high-efficiency energy-saving motor be reduced to 86dB (A), than the low 26dB (A) of oil field used same specification Y series motor, improve the operational environment in oil field, reduced the able-bodied harm of workman.
Description of drawings
Fig. 1 is an overall structure front view of the present utility model, and Fig. 2 is the cutaway view of the left view of Fig. 1.
Embodiment
Embodiment one: shown in Fig. 1-2, the electric machine casing of the described a kind of built-in absorbent treatment of present embodiment comprises outer support housing 1 and two dividing plates 4, also comprise built-in absorbent treatment 2 and interior support housing 3, described outer support housing 1 is sleeved on the interior support housing 2, the dividing plate 4 that has 2, two of the built-in absorbent treatments of one deck to be used for fixing motor between outer support housing 1 and the interior support housing 3 is vertically set in the interior support housing 3 side by side.The acoustically effective of present embodiment reaches 20dB (A), can make the airborne noise of high-efficiency energy-saving motor be reduced to 86dB (A), has improved the operational environment in oil field.
Embodiment two: shown in Fig. 1-2, the electric machine casing of the described a kind of built-in absorbent treatment of present embodiment also comprises several resiliency supported muscle 5, described several resiliency supported muscle 5 are arranged between two dividing plates 4, and the two ends of each resiliency supported muscle 5 are connected with a dividing plate 4 respectively.Vibrating noise and noise of air that present embodiment has produced when further having reduced motor work.Other composition and annexation are identical with embodiment one.
Embodiment three: shown in Fig. 1-2, outer support housing 1 bilateral symmetry of the electric machine casing of the described a kind of built-in absorbent treatment of present embodiment is provided with handgrip 6.Present embodiment has guaranteed the workman position of travel motor easily, has made things convenient for the workman to use motor to carry out oil field operation.Other composition and annexation are identical with embodiment one.
Embodiment four: shown in Fig. 1-2, the built-in absorbent treatment 2 of the electric machine casing of the described a kind of built-in absorbent treatment of present embodiment is by the cotton built-in absorbent treatment of making 2 of sound absorption.Other composition and annexation are identical with embodiment one, two, three or four.
Operation principle
Motor is put between two dividing plates 4, motor is fixedlyed connected with interior support housing 3, the most of noise that is produced during motor work is absorbed by built-in absorbent treatment 2, reduced the ambient air noise, simultaneously resiliency supported muscle 5 can reduce the vibration that produces owing to motor work, thereby has further reduced the ambient air noise.
