How to reduce the noise of the sewage pump?

Noise is a serious problem in recent years, the community has been concerned but how can not solve the outdoors, ubiquitous noise with you want to walk to the eardrum, Ann quietly will not work, home will be all kinds of noise continue to plague, sewage pump noise is one of the sources. A lot of residential district environment in order to install sewage pump , but the noise is large, many residential tenants are noise of the sewage pump to spiritual pollution, the night is often quarrel can't sleep, children and elderly households is more serious. Therefore, we need to reduce the noise generated by the pump, the specific operation is divided into the following six steps:

1, each unit should be set up a separate foundation to prevent resonance, the pump foundation should be based on the weight of a large, and should be provided with a rubber vibration isolation pad vibration, thereby reducing the vibration noise;

2, the sewage pump suction pipe and outlet pipe should be installed on the flexible rubber joint, flexible rubber pipes of different diameter pipe. The number of base isolated generally each flexible rubber joint insertion loss is 15 20dB to estimate the isolation effect of isolation pipe fittings;

3, the pressure pipe on the installation of water hammer eliminator;

4, the sewage pumping station should not be placed directly on the window window wells;

5, with the sewage pump connected to the pipeline, should support vibration isolation measures, pipeline crossing roof or side walls of the pump should be installed between the casing and the casing pipe filled with non combustible flexible materials;

6, reduce the noise, should give priority to the use of low speed vertical pump.
