Description

Technical Field

[0001] The utility model belongs to the technical field of motor pumps, and more specifically, relates to a vibration reduction and noise reduction structure of a motor pump housing. Background Art

[0002] A motor pump is an integrated hydraulic power unit that combines an electric motor and a hydraulic pump, sharing a rotor and housing. It delivers or boosts fluid pressure by driving the impeller within the pump. During use, the motor pump vibrates due to the operation of the motor and the rapid rotation of the impeller, generating significant noise due to resonance. Therefore, a vibration-damping and noise-reducing structure for the motor pump housing is required. Existing motor pump housing vibration-damping and noise-reducing structures primarily utilize a fixed base to centrally secure the motor pump, or a rubber pad to separate the motor pump and mounting base. The fixed base centrally secures the motor pump to reduce vibration caused by unstable installation, while the rubber pad separates the motor pump and mounting base, effectively isolating and reducing vibration transmission.

[0003] Existing application number CN202122746145.4 This utility model discloses a shock-absorbing and noise-reducing structure for a water purifier water pump, including a water pump shock-absorbing and noise-reducing protective housing, a mounting plate, and a noise-reducing sealing plate. The water pump shock-absorbing and noise-reducing protective housing is installed on the outside of the water pump by inlaying. One end of the water pump shock-absorbing and noise-reducing protective housing is provided with a noise-reducing sealing cover, and both sides of the top of the inner top of the noise-reducing sealing cover are provided with angle positioning pads. The water pump in the utility model is further equipped with a water pump shock-absorbing and noise-reducing protective housing on the outside. The water pump shock-absorbing and noise-reducing protective housing can completely seal the water pump to form an efficient sealed space, eliminating the noise generated during use of the water pump, and the interior of the water pump shock-absorbing and noise-reducing protective housing is provided with a second double-spring shock-absorbing plate, a single-spring shock-absorbing plate, and a supporting noise-reducing column. The second double-spring shock-absorbing plate and the single-spring shock-absorbing plate can strengthen the support and positioning effect of the water pump motor, thereby reducing the space for vibration.

[0004] Based on the above, the existing shock-absorbing and noise-reducing structure of the motor pump housing mainly achieves shock absorption and noise reduction through a fixed seat or rubber pad. However, during the operation of the motor pump, the shaft, bearings, etc. may wear and deviate. This deviation not only aggravates the vibration amplitude during rotation, but also the existing shock-absorbing and noise-reducing structure does not facilitate staff to detect problems and perform maintenance in a timely manner after the vibration amplitude is reduced, and may also have an adverse effect on the overall stability and operating efficiency of the equipment. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a shock-absorbing and noise-reducing structure for a motor pump housing to solve the problem that the existing shock-absorbing and noise-reducing structure of the motor pump housing mainly performs shock-absorbing and noise-reducing by means of a fixed seat or a rubber pad, but during the operation of the motor pump, the rotating shaft, bearings, etc. may be worn and offset. This offset not only aggravates the vibration amplitude during rotation, but also after the existing shock-absorbing and noise-reducing structure reduces the vibration amplitude, it is inconvenient for staff to discover problems and perform maintenance in time, and it may also have an adverse effect on the overall stability and operating efficiency of the equipment.

[0006] The purpose and effect of the vibration reduction and noise reduction structure of the motor pump housing of the utility model are achieved by the following specific technical means:
