Analysis of the reasons why the self-priming pump will have loud sound and vibration
There are many reasons for the large sound and vibration of the self-priming pump. In order to effectively solve this problem, we need to start from multiple aspects and adopt comprehensive measures. We can effectively reduce the sound and vibration of the self-priming pump, ensure its stable operation and reduce noise pollution to the surrounding environment.
1. Analysis of the reasons for the large sound and vibration of the self-priming pump
1) Motor wiring problem: The wrong connection of the positive and negative poles of the motor terminal will cause the motor to reverse, and then the impeller will reverse, generating noise and vibration.
2) Shaft eccentricity: When the shaft is eccentric, the impeller will rub against the pump body during rotation, resulting in large sound vibration.
3) Inlet air entry: The self-priming pump needs to be filled with water or has water before starting. If air enters the inlet, it will cause gas-liquid mixing, increasing the sound vibration.
4) Impeller foreign matter entanglement: When the impeller is entangled with foreign matter, the friction between the foreign matter and the cover will generate noise and vibration.
5) Impeller damage: Impeller damage will cause uneven force during the pumping process, thereby generating sound vibration.
2. Countermeasures to solve the problem of large sound and vibration of self-priming pumps
1) Check the motor wiring: Ensure that the motor wiring is correct to avoid sound vibration caused by motor reversal.
2) Adjust the axis position: Accurately adjust the axis to ensure that it maintains an appropriate gap with the pump body during operation to avoid sound vibration caused by friction.
3) Check the inlet sealing: Strengthen the inlet sealing to ensure that the pump body is filled with water or has water before starting to avoid air entering and causing gas-liquid mixing.
4) Clean foreign matter on the impeller: Regularly clean foreign matter on the impeller to avoid sound vibration caused by foreign matter entanglement.
5) Replace damaged impellers: Replace damaged impellers in time to ensure uniform force during pumping liquid and reduce sound vibration.
