        How to deal with electrophoresis paint magnetic pump idling?

        Date:2019-03-03 Author: Click:

        In the operation of the electrophoretic paint magnetic pump, idling of the pump is not allowed. The majority of users are afraid of idling of the electrophoretic paint magnetic pump. The reason for this is that they do not understand the causes of idling and how to solve it well.If the electrophoresis paint magnetic pump idling in less than 1 minute time will not cause damage. 

        The reasons for the idling of the electrophoretic paint magnetic pump are as follows: insufficient inlet medium or insufficient inlet pressure of the water pump, or the water pump inlet pipe is blocked, or the air in the pump cavity is not exhausted.

        Electrophoretic paint magnetic pump idling, impeller no contact or little contact with the medium, can not work effectively, liquid can not be transported out of the normal, these are useless.Because there is no effective work, the motor by the load is very small, the current is also very small, the impact on the motor will be nothing, pump idling effect on the pump is indeed fatal.The idling pump is easy to cavitate and cause damage to the pump body and over-current parts.Idling pump mechanical seal form or packing seal form idling, will not get liquid lubrication, resulting in dry grinding, thus rapid damage;Idling pump rotor parts, pump heat, there is no liquid cooling, by the role of thermal expansion and contraction of those narrow gap position (such as seal ring) is easy to bite dead. 


        Warning and maintenance of idling of electrophoresis paint magnetic pump it is suggested to upgrade the design of electrophoresis paint magnetic pump to a higher level:

        1, the electrophoresis paint magnetic pump clearance position for each treatment, in the allowed conditions to expand, to prevent biting death;

        2, the electrophoresis paint magnetic pump shaft for special processing, conditioning, heat treatment, and so on, to improve the hardness, with a low flexible material, to prevent idling large swing and kill;

        3,Use machine seals and packing cavities that do not need to be lubricated by liquid media;

        4, choose sealed self-lubrication without oil shaft seal.

        The pump chamber of the electrophoretic paint magnetic pump is larger than that of other electrophoretic paint magnetic pumps and has a position for water storage.Before the normal operation of the electrophoretic paint magnetic pump, the cavity body should be filled with liquid. Before the operation, there is a period of self-suction time, which continuously drains air to the pump body. This period of time belongs to partial idling. 

        Set up the idling induction system.Through the modern equipment for real-time monitoring of the pump, when the electrophoresis paint magnetic pump idling immediately alarm and automatic shutdown, to protect the safety of the unit.
