                              What kinds of cooling shielding pump?

                              2020-09-20 16:35:00

                              Through this period of understanding, I believe that we are not unfamiliar with the shield pump, but for customers who want to further understand the relevant knowledge of this product, these contents are still not enough. Today small make up about the shielding pump cooling knowledge to share with you, I hope to cause your attention, let you have a deep understanding of the shielding pump. So when you buy the use of shield pump can also do know, do not hurry, hope to inspire you and help. Shielded pump service time is long, bearing and other key parts of the temperature will rise, resulting in the pump can not be used normally, at this time, we need to take a certain way of cooling to reduce the temperature of the pump. This requires us to understand the pump common cooling way, we have a look at the following content!






                              Shielding pump cooling means has two kinds, one kind is with the aid of the cycle of working medium itself to absorb the heat in operation, namely from the pump discharge nozzles lead a liquid (subject to filter) from the tail into the electric motor bearings, then through the clearance between the rotor and stator bearing such as access to return before and impeller, form the circulating cooling system, in order to achieve the purpose of cooling, conveying liquid at normal temperature in ordinary shield pump often use this way for cooling; The other is the internal cooling of the rotor, the rotor is cooled with circulating oil, at both ends of the pump shaft are oil holes, oil diameter shaft head into, through the inner wall of the rotor and then discharged from the other end, when the pump is working under high pressure difference, can be used in this cooling way.


                              Shielding pump common cooling methods are mainly the above two, the actual use, we can choose the specific use of a cooling method according to the temperature and boiling point of the material, but is usually the former is the priority design.
