Shanghai on behalf of shielded pump Co., Ltd. shielded pump shielding the advantages and disadvantages

[Japan Pump Network News] Shanghai Machine Shielded Pump Co., Ltd. is a company specializing in the production and sale of shielded pump business, then the production and sale of shielded pump what are the advantages and disadvantages? If you are interested in this issue, then Xiao Bian down for everyone to introduce the Japanese-made shielded pump shield shielded pump company's advantages and disadvantages. Shanghai Japan Masaki shielded pump Co., Ltd. shielded pump production advantages and disadvantages of a shielded pump advantages: (1) fully enclosed. There is no dynamic seal on the structure, there is a static seal at the pump housing, so it is completely leak-free and is especially suitable for the transport of flammable, explosive, valuable liquids and toxic, corrosive and radioactive liquids. (2) high safety. Rotor and stator each have a shield sleeve so that the motor rotor and stator is not in contact with the material, even if the shield sleeve rupture, it will not produce the risk of external leakage. (3) Compact footprint. Pump and motor system as a whole, disassembly do not need to find the center. Low requirements on the base and the foundation, and the daily maintenance workload, low maintenance costs. (4) smooth operation, low noise, without lubricating oil. Because there is no rolling bearing and motor fan, so no need to add lubricating oil, and low noise. (5) a wide range of use. High temperature, high pressure, low temperature, high melting point and other conditions can meet the requirements. Second, the shortcomings of shielded pumps: (1) As the shielded pump with sliding bearings, and is transported by the media to lubricate, so poor lubrication of the media should not be shielded pump delivery. Generally suitable for shielding the viscosity of the pump medium is 0.1 ~ 20mPa.s. (2) Shielded pump efficiency is usually lower than the single-end mechanical seal centrifugal pump, and double-sided mechanical seal centrifugal pump roughly the same. (3) For a long period of time, operating at a low flow rate, shielding pump efficiency is low, will lead to heat, liquid evaporation, resulting in dry pump rotation, thus damaging the sliding bearing.
