Sewage pump mechanical characteristics

Sewage pump mechanical characteristics [student question] Sewage pump mechanical characteristics? [Answer] ①The use of a common single-blade or double-blade impeller structure greatly improves the ability of the dirt to pass through the mechanical seal. It can effectively pass 5 times the diameter of the pump diameter and solid particles with a diameter of about 50% of the pump diameter. ②The mechanical seal adopts a new type of hard tungsten carbide material that is resistant to corrosion of the mechanical seal. Together, the seal is improved to a double end seal, so that it can operate in the oil chamber for a long time, and the pump can safely and continuously run for more than 8,000 hours. ③The whole structure is compact, small in size, low in noise, significant in energy saving, convenient for maintenance, and no need to build a mechanical shaft seal pump room. It can be operated by submerging in the water, which greatly reduces the project cost. ④ A high-precision anti-interference water leakage detection sensor is installed in the sealed oil chamber of the pump, and thermal elements are embedded in the stator winding, which is sure to maintain the pump motor. ⑤It can be equipped with a fully active safety maintenance control cabinet according to user needs, and affirmative maintenance of the pump's water leakage, leakage, overload and over temperature, etc., improves the safety and reliability of the product. ⑥ The float switch can actively control the start and stop of the pump according to the changes in the required liquid, without special guards, and is extremely convenient to use. ⑦The dual-rail active coupling device system can be equipped according to user requirements, which brings great convenience to installation and repair, and people do not need to enter the sump for this. ⑧It can be used in the full range of head, and ensure that the motor will not be overloaded. ⑨There are two different installation methods, fixed active coupling device system and mobile free device system. The above content is assembled based on the questions encountered by the students in the actual work for reference. If you have any questions, please communicate and correct them in time.
