Submersible pump structure, materials and auxiliary systems due to the emergence of cooling problems, put forward higher requirements, also noteworthy is the ketone, ester, ether for a variety of equipment solubility, so Nanjing lanshen Pump Corp.LTD. explain the cooling problem of submersible pump:
1.The media which temperature is below 120 ℃, submersible pumps are usually not set up a special cooling system, will use its own media to lubricate and cool;
2.For medium which temperature between 120 ℃ and 300 ℃, usually it will be equipped with cooling chamber in the pump cover, sealed chamber should also be connected to the cooling fluid, to be equipped with double mechanical seal;
3.For medium which temperature more than 300 ℃, not only the pump head part of the need for cooling, suspension bearing room should also be equipped with cooling system, submersible pump structure is generally the central support form, the best mechanical seal metal bellows type;
4.The maximum temperature when use submersible pump can up to 200 ℃.
5.Submersible pump life problems, material pitting corrosion problems, static sealing reliability issues are noteworthy, should be injected into the sealed cavity isolation fluid, the pressure is generally higher than the medium pressure 0.07 ~ 0.1MPa.
The above content is introduction of submersible pump cooling problems, in the grasp of these will help us to use better and improve the efficiency of work.
