杭州潜水泵的优点和缺点是什么？杭州潜水泵的优点：杭州潜水泵外形美观，结构简单，安装使用方便，可移动使用，具有灵活性。潜水泵的缺点：1、结构上有限制，比离心泵的扬程范围小，因此选用范围受到影响。2、杭州潜水泵的工作部分浸在介质中，安装与维修比离心泵困难，同时零件易损导致整机的使用寿命远远低于离心泵。3、固定湿式安装需要自动耦合装置，安装检修时需吊装设备，增大附属设备投资。4、电缆及密封件易老化，导致漏电。5、电机及轴承等不宜在>50度介质中工作。6、电机靠介质冷却，露出液面不可超过1/2，控制易于出问题且排液不彻底。7、杭州潜水泵出口与耦合装置借口不严，导致出力不足。8、杭州潜水泵大发云电机及机壳在腐蚀性介质中使用寿命短。9、密封件损坏，导致电机短路烧毁。

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.
