杭州潛水泵的優點和缺點是什麽？杭州潛水（shuǐ）泵（bèng）的優點：杭州潛水泵外形美觀，結構簡（jiǎn）單（dān），安裝使（shǐ）用方便，可移動使（shǐ）用，具有靈（líng）活（huó）性。潛水泵的缺點：1、結構上有限製，比離（lí）心泵的揚程範圍小，因（yīn）此選用範（fàn）圍受到影響。2、杭州潛水泵的工作部分浸在介質中，安裝（zhuāng）與維修比離心泵困難，同時零件易損導（dǎo）致整（zhěng）機的使用壽命遠遠低於（yú）離心泵。3、固定（dìng）濕式安裝需要自動耦合裝置，安裝檢修（xiū）時（shí）需吊裝設備，增大附屬（shǔ）設備投資。4、電纜及密封件易老化，導致漏電。5、電機及軸承（chéng）等不宜（yí）在>50度介質中工作。6、電機靠介質冷卻，露出液麵不可超過1/2，控製（zhì）易於出（chū）問題且排液不徹底。7、杭州潛水泵出口與耦合裝置借口不嚴，導致出力不足。8、杭州潛水泵電機及機殼在腐蝕性介質中（zhōng）使用壽命短。9、密封件損壞，導致電機短路燒毀。

What are the advantages and disadvantages of hangzhou submersible pump? Advantages of hangzhou submersible pump: hangzhou submersible pump beautiful appearance, simple structure, easy to install and use, mobiles use, flexibility. Disadvantages of submersible pump: 1, the structure is limited, than the centrifugal pump head range is small, so the selection range is affected. 2, the work of hangzhou submersible pump immersed in the medium, installation and maintenance than the centrifugal pump difficult, at the same time, the parts easy to damage the service life of the whole machine is far lower than the centrifugal pump. 3. Automatic coupling device is required for fixed wet installation. Hoisting equipment is required for installation and maintenance to increase the investment of ancillary equipment. 4. Cables and seals are easy to age, leading to leakage. 5, the motor and bearing should not work in >50 degree medium. 6. The motor is cooled by the medium, and the exposed liquid level shall not exceed 1/2. The control is prone to problems and liquid drainage is not complete. 7, hangzhou submersible pump export and coupling device excuse is not strict, resulting in insufficient output. 8. Submersible pump motor and casing have short service life in corrosive media. 9. The seal is damaged, which causes the motor to be short-circuited and burned.
