杭州潛水泵的（de）優點和缺點是什（shí）麽？杭州潛水泵的優點：杭州潛水泵外形美觀，結構簡（jiǎn）單，安裝使用方（fāng）便，可移動使用，具有靈（líng）活性。潛水泵的缺點：1、結構（gòu）上有限製，比離心（xīn）泵的揚程範圍小，因此選用範（fàn）圍受到（dào）影響。2、杭州潛水泵的工作部（bù）分浸在介質中，安裝與維修（xiū）比離心（xīn）泵困難，同時零件易損導致整機的使用壽命遠遠低於離心泵。3、固定濕式安裝需要自動耦合裝（zhuāng）置，安裝（zhuāng）檢修時需吊（diào）裝設備，增大附屬設備投資（zī）。4、電纜及密封（fēng）件易老化，導（dǎo）致漏（lòu）電。5、電機及（jí）軸承等不宜在（zài）>50度介質中工作。6、電機靠介質冷卻，露出（chū）液麵不（bú）可超過1/2，控製易（yì）於（yú）出問題且排（pái）液不徹底。7、杭州潛水泵出口與耦（ǒu）合裝（zhuāng）置借口（kǒu）不嚴，導致出力不足。8、杭州潛水泵（bèng）電機及機殼在腐蝕性介質中使用壽命短。9、密（mì）封件損壞（huài），導（dǎo）致電機短路（lù）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.
