Abstract

The invention provides a noise reducer for a pump, which is composed of a base, a vibration isolator and an enclosing cover. The vibration isolator is arranged on the base, and a pedstral used for the installation of the pump is arranged on the vibration isolator; the enclosing cover is composed of an enclosing wall and an enclosing top, the enclosing wall may be in the shape of a square column, a cylinder or a polygon prism and comprises a block or a plurality of block components, and each block of the block components is connected with each other in a seamless way; air outlets are arranged on four sides of the enclosing wall; and corresponding positions thereof are provided with trepan borings of inlet and outlet pipelines of the pump and the trepan borings of wires of a motor, and each trepan boring is sealed via sealing strips; the upper end and the lower end of the enclosing wall are respectively connected with the enclosing top and the base in a sealing way, an air inlet is arranged in the middle of the enclosing top; noise elimination screens are respectively fixed on external sides of the air inlet and the air outlet, and a noise elimination plate is fixed in the enclosing cover at a position corresponding to the pump. The invention has the advantages of sound absorption, noise elimination, sound insulation and vibration isolation of the pump, fine noise elimination effect, novel structure, convenient assembling and disassembling, good heat dissipation and low cost.

Description

1. Technical field [0001] The invention relates to the technical field of a noise reduction device related to a water pump, in particular to a water pump noise reducer for reducing the noise of a water pump. 2. Background technology [0002] At present, the noise generated by water pumps, especially the noise generated by water pumps for secondary pressurized water supply in high-rise buildings, has reached the level of affecting people's normal life and physical and mental health. The noise of the water pump mainly comes from two aspects: mechanical noise and electrical noise. The noise generated by machinery mainly comes from the running noise and vibration noise of the water pump; the electrical noise mainly comes from the frequency conversion electromagnetic noise and rotor rotation noise generated after the motor is powered on. Suffering from water pump noise interference for a long time can cause pathological and psychological diseases, easily lead to the occurrence o...
