Pipeline pumps are a relatively quiet product in pump products, but because some of the conditions and problems can increase the noise of the pipeline pump, sometimes the noise is even too much to bear. The noise of the pipeline pump is also a relatively common situation that the user responds to us during the application process. After studying their specific conditions, the investigation is mainly caused by the following reasons.
1. Pump noise caused by improper installation
At the time of the installation, we pay attention to one level, two stability and three strengths. The level refers to the level. When the pump is installed, the foot must be level (in another case, it cannot be tilted). The stability means that it must be stable, and it should not be loose and sway. Robustness means that the root of the device must be strong and stable, and the other side of the device cannot be hung on the other side. In addition, in order to avoid the noise caused by the resonance, the bottom of the pipeline pump should be equipped with a vibration pad, and the inlet and outlet must be equipped with an expansion joint (soft joint). Why do you want to do this? Because the pump has a certain noise and is accompanied by fine vibration during the operation of the pump, if there is no anti-vibration pad, there will be a chain reaction between the pump and the base, and the resonance will strengthen the vibration. If the inlet and outlet are not equipped with expansion joints, the vibration and noise of the motor will be transmitted to the pipeline. The pipeline is like a consensus cavity, which will further strengthen the vibration and noise. The pipeline will also emit sound and vibration under the action of water flow resistance and pressure in the pipeline, so it is necessary to install the expansion joint to eliminate the resonance and consensus between the pipeline and the water pump.
2. Noise caused by imbalance of pump impeller
Some pumps use a long time to impinge the impeller in the work or being sucked into the pump cavity or cause the impeller to lose balance. The left and right weights are heavy, and the tail is tailed. This will cause the motor to work at high speed. The motor bearing bearing gravity is different in weight and noise is generated. Together with this, the motor shaft is also affected by the unbalanced impeller to generate noise.
3. Noise caused by bearing damage
Some customers use the water pump device outdoors and use it without any cover. Rainwater will be sucked from the motor hood by the air vane. If it enters the back cover of the motor, the bearing will oxidize and rust, and the bearing ball will not be smooth. , it will make mechanical noise. If it is installed indoors, this kind of problem will not be presented, but there will be another situation. If the mechanical seal is damaged and not replaced in time, it will be used as it is. If there is no water stop, the mechanical seal will lose the sealing effect. The pressure inside causes the water in the pump body to spray out. The water retaining ring on the motor shaft can maintain the motor bearing without water intrusion, but the water spray is more and more intrusive into the bearing chamber and will damage the bearing. At this time, the sound of the pump in the work may be as loud as the train pressing the rails.
