Abstract
The utility model relates to a kind of water pump motor silencer, comprises housing, inlet hole and air outlet hole.Be provided with the first expansion chamber, the 3rd expansion chamber and the second expansion chamber in the housing of baffler, the first expansion chamber is positioned at the side of suction port, and the second expansion chamber and the 3rd expansion chamber are positioned at the opposite side of suction port.Suction port is communicated with the first expansion chamber, and the first expansion chamber is communicated with by passageway with the second expansion chamber.Be provided with dividing plate between second expansion chamber and the 3rd expansion chamber, dividing plate one end is provided with gap, and the second expansion chamber is communicated with the 3rd expansion chamber by gap, and the 3rd expansion chamber is communicated with air outlet hole.The utility model, by arranging three expansion chamber, reduces the noise of water pump motor, improves the safety in utilization of baffler and the working efficiency of water pump.
Description
Technical field
The utility model belongs to engine powered auxiliary equipment technical field, relates to a kind of water pump motor silencer.
Background technique
The pulsing airflow produced when baffler traditional at present works, needing twice expansion, contraction through intake and exhaust room, airspeed is cushioned, and frequency of sound wave is changed, and then noise is reduced, and realizes the function of noise reduction.But the pulsing airflow buffer function that current baffler discharges generation to motor exhaust is little, during exhaust, back pressure is large, and erasure effect is poor.And baffler did not have good safety guarantee, the relief opening of the spark of discharging in motor exhaust from baffler operationally, was easily discharged, easy initiation fire by baffler.Muffler structure on conventional water pump motor is all the steel baffler of stamping riveting, and weight is large, and erasure effect is poor, can reach 87 decibels, and outward appearance is not beautiful, is very easy to get rusty, processing and fabricating step length how consuming time.
Model utility content
The purpose of this utility model is to provide a kind of water pump motor silencer, to reduce the noise of water pump motor, improves the safety in utilization of baffler and the working efficiency of water pump.
The technical solution of the utility model is: water pump motor silencer, comprises housing, inlet hole and air outlet hole.Be provided with the first expansion chamber, the 3rd expansion chamber and the second expansion chamber in the housing of baffler, the first expansion chamber is positioned at the side of suction port, and the second expansion chamber and the 3rd expansion chamber are positioned at the opposite side of suction port.Suction port is communicated with the first expansion chamber, and the first expansion chamber is communicated with by passageway with the second expansion chamber.Be provided with dividing plate between second expansion chamber and the 3rd expansion chamber, dividing plate one end is provided with gap, and the second expansion chamber is communicated with the 3rd expansion chamber by gap, and the 3rd expansion chamber is communicated with air outlet hole.
The outside of housing is provided with stiffening rib.Baffler is provided with fixed hole.
Be divided into three expansion chamber in the utility model water pump motor silencer, reduce the noise of water pump motor, improve the safety in utilization of baffler and the working efficiency of water pump.The stiffening rib surface temperature of projection is lower than irony baffler temperature, can reduce human body and surprisingly touch the scald caused.The utility model good integrity, lightweight, outward appearance is beautiful.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model water pump motor silencer;
Fig. 2 is the schematic appearance () of baffler;
Fig. 3 is the schematic appearance (two) of baffler; .
Wherein:
1-air outlet hole, the 2-the three expansion chamber, the 3-the second expansion chamber, 4-inlet hole, the 5-the first expansion chamber, 6-fixed hole, 7-housing, 8-stiffening rib, 9-dividing plate, 10-gap, 11-passageway.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.The utility model protection domain is not limited to embodiment, and those skilled in the art make the scope that any change also belongs to the utility model protection in the scope that claim limits.
The utility model water pump motor silencer, as shown in FIG. 1 to 3, comprises housing 7, inlet hole 4, air outlet hole 1 and fixed hole 6.Be provided with the side that the first expansion chamber 5, the 3rd expansion chamber 2 and the second expansion chamber 3, first expansion chamber are positioned at suction port in the housing of baffler, the second expansion chamber and the 3rd expansion chamber are positioned at the opposite side of suction port.Suction port is communicated with the first expansion chamber, and the first expansion chamber is communicated with by passageway 11 with the second expansion chamber.Be provided with dividing plate 9 between second expansion chamber and the 3rd expansion chamber, dividing plate one end is provided with gap 10, second expansion chamber and is communicated with the 3rd expansion chamber by gap, and the 3rd expansion chamber is communicated with air outlet hole.The outside of housing is provided with stiffening rib 8.
The utility model good integrity, be inside divided into three expansion chamber, noise can be down to 75 decibels.The stiffening rib 8 of the multiple tracks projection of housing outer surface effectively can improve the intensity under high temperature, and the heat dissipation rate of aluminium is fast, and the stiffening rib surface temperature of projection is lower than irony baffler temperature, can reduce human body and surprisingly touch the scald caused.The utility model entirety adopts aluminum alloy casting, lightweight, profile create an aesthetic feeling.
