杭州潛水泵的優(yōu)點和缺點是什么？杭州潛水泵的優(yōu)點：杭州潛水泵外形美觀，結(jié)構(gòu)簡單，安裝使用方便，可移動使用，具有靈活性。潛水泵的缺點：1、結(jié)構(gòu)上有限制，比離心泵的揚程范圍小，因此選用范圍受到影響。2、杭州潛水泵的工作部分浸在介質(zhì)中，安裝與維修比離心泵困難，同時零件易損導(dǎo)致整機的使用壽命遠(yuǎn)遠(yuǎn)低于離心泵。3、固定濕式安裝需要自動耦合裝置，安裝檢修時需吊裝設(shè)備，增大附屬設(shè)備投資。4、電纜及密封件易老化，導(dǎo)致漏電。5、電機及軸承等不宜在>50度介質(zhì)中工作。6、電機靠介質(zhì)冷卻，露出液面不可超過1/2，控制易于出問題且排液不。7、杭州潛水泵出口與耦合裝置借口不嚴(yán)，導(dǎo)致出力不足。8、杭州潛水泵電機及機殼在腐蝕性介質(zhì)中使用壽命短。9、密封件損壞，導(dǎo)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, mobile 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.
