The invention relates to the technical field of water pump noise reduction, in particular to a vertical water pump sound absorption and noise reduction device and a mounting method thereof. The device comprises a top plate surface, a cylinder cover, a bottom plate surface, a shape groove, a side cylinder body, a plug pin, a fixing support, a fixing plate, a bolt, foam metal, sound absorption sponge, a square hole and a cylinder outer wall. According to the device, through splicing assembly, the transportation and assembly speed is increased. The whole body of the device is made of titanium alloy, the interior is of a cavity structure, square holes are formed in the inner wall, and the cavity is filled with novel laminated composite materials. The material is of a three-layer design, two layers of sound-absorbing sponges are arranged outside and are adhered to the inner surface of the board body through super glue, foam metal is filled between the two layers of sound-absorbing sponges, and the joint of the foam metal and the two layers of sound-absorbing sponges is also adhered through super glue. And a water inlet and a water outlet can be reserved on the barrel according to the actual condition of the vertical water pump. The device plays a good role in sound absorption and noise reduction, and the damage of noise generated when the water pump operates to the water pump and the human body is reduced.
Description
technical field [0001] The invention relates to the technical field of water pump noise reduction, in particular to a vertical water pump sound absorption and noise reduction device and an installation method thereof. Background technique [0002] Vertical water pump is a mechanical device that transports water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, transport liquid, gas mixture and liquid containing suspended solids, and provides the mechanical energy generated by the motor to the liquid, so that the liquid Boost, boost liquid energy. [0003] In the process of conveying the liquid in the existing vertical water pump, the action of the impeller and the liquid, due to the hydraulic vibration, produces a large noise, and the resulting sound pollution will affect the surrounding environment, and the noise will also cause great damage to the pump itself and the human body. Health also has many disadvantages. SUMMARY OF THE INVENTION [0004]...
