Mechanical characteristics of stainless steel sewage pump
The sewage pump is a kind of pump in which the pump and the motor are integrated and submerged into the liquid at the same time. Compared with the general horizontal pump or vertical sewage pump, the sewage pump has a compact structure and a small footprint. Easy installation and maintenance Small sewage pumps can be installed freely, and large sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is quite convenient for installation and maintenance. Long continuous operation time.
Sewage pumps are coaxial with the motor, the shaft is short, and the weight of the rotating parts is light, so the load (radial) on the bearings is relatively small, and the service life is much longer than that of ordinary pumps. There is no problem of cavitation damage and water diversion. It brings great convenience to the operator. Small vibration and noise, low motor temperature rise, no pollution to the environment.
Mechanical features:
①Using the advanced single-blade or double-blade impeller structure, the passing capacity of the dirt is greatly improved, and it can effectively pass through the fibrous material 5 times the pump caliber and the solid particles whose diameter is about 50% of the pump caliber.
②The mechanical seal adopts a new type of hard and corrosion-resistant tungsten carbide material. At the same time, the seal is improved to a double-face seal, so that it can run in the oil chamber for a long time, and the pump can run safely and continuously for more than 8,000 hours.
③The overall structure is compact, the volume is small, the noise is low, the energy saving is high, and the maintenance is convenient. There is no need to build a pump room, and it can work when it is submerged in the water, which greatly reduces the project cost.
④The seal oil chamber of the pump is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal sensor is embedded in the stator winding to protect the pump motor.
⑤A fully automatic safety protection control cabinet can be equipped according to user needs to protect the pump from water leakage, electric leakage, overload and over-temperature, etc., which improves the safety and reliability of the product.
⑥ The float switch can automatically control the start and stop of the pump according to the change of the liquid required.
⑦A dual-rail automatic coupling installation system can be equipped according to user needs, which brings great convenience to installation and maintenance, people do not have to enter the sewage pit for this.
⑧It can be used in the full range of head, ensuring that the motor will not be overloaded.
