The cause and treatment of the self-priming pump motor

Self-priming pump occurs when the motor is hot during operation, and many users are not sure about the cause of the self-priming pump motor hot and the self-priming pump motor hot treatment, and even some users will The reason why the self-priming pump motor is hot is the quality of the motor, so it is necessary to share with you the reasons for the hotness of the self-priming pump motor and the treatment of the self-priming pump motor:
Due to the wrong selection of the self-priming pump, for example, the self-priming pump with a working condition of 15 meters can meet the working conditions, and some users choose to purchase the self-priming pump to ask the pump supplier for the self-priming pump. The lift of the product should reach about 30 meters. As a result, the motor is hot after the self-priming pump is installed and used. The main reason is that the actual delivery head is much lower than the lift of the self-priming pump, resulting in an increase in the motor current. The self-priming pump motor is hot. In serious cases, the phenomenon of burning the motor will occur. The treatment method of the self-priming pump motor is to close the small outlet valve to control the flow of the self-priming pump to reduce the current. If the head difference is too large, the small valve can not solve the problem, then only the low lift self-priming pump products are replaced.
   Due to the large proportion of the medium to be transported, it is also the cause of the ironing of the self-priming pump motor. In this case, only the increase of the power of the motor can solve the phenomenon that the self-priming pump motor is hot.
   If the temperature of the delivered medium is high for a long time, the temperature of the pump medium will be transmitted to the motor. This will also be the cause of the hotening of the self-priming pump motor. The temperature of the delivered medium is too high. It is recommended to use self-priming with a coupling. The liquids contained in the pump products contain particles and debris. ZW self-priming sewage pump can be used. It is recommended to use self-priming centrifugal pump products for general hot water.
   Due to the unstable voltage of the user using the site or the cable of the self-priming pump motor is not up to standard, the self-priming pump motor is hot. The treatment method of the self-priming pump motor can only solve the voltage problem. Replace the standard cable.
   Self-priming pump mechanical seal is too tight due to spring adjustment during installation and replacement. Manually cranking is very difficult. This is also the reason why the self-priming pump motor is hot. The treatment method of this type of self-priming pump motor is to re-adjust the spring compression. the amount.
   The self-priming pump has poor assembly quality, some parts have friction phenomenon, or the balance between the self-priming pump motor and the pump shaft is not good enough. The self-priming pump motor is hot because of the different heart. This self-priming pump motor is hot. The treatment is to check the assembly quality of the self-priming pump and re-assemble the calibration.
