Lw Series Vertical Nonclogging Sewage Pump
Sewage pumps is easy to install and use, and has a reasonable structure, and at the same time, it avoids the disadvantages of burning the motor due to water leakage of the mechanical seal. Due to the unique single (double) channel impeller, the sewage discharge capacity is strong, and it can effectively pass through the fibrous matter 5 times the diameter of the pump and the solid particles whose diameter is 50% of the pump diameter.
1. The pump is a vertical structure. If the pump is equipped with an outdoor motor, there is no need to build a pump room, and it can be directly installed outdoors to save money.
2. It can be used in the full range of head without overloading the motor
3. It can be equipped with square plate and circular plate installation system according to the needs of users, which brings great convenience to installation and maintenance, and people do not need to enter the sewage pit
4. The automatic control cabinet can automatically control the overrun and stop of the pump according to the change of the required liquid level.
5. The overall structure is compact, the volume is small, the noise is small, the energy-saving effect is remarkable, and the maintenance is convenient.
6. The unique double-blade impeller structure is adopted, which greatly improves the passing capacity of the dirt, and can effectively pass through fibrous materials 5 times the diameter of the pump and solid particles whose diameter is about 50% of the pump diameter.
7. The mechanical seal adopts a new type of hard and corrosion-resistant alloy to silicon carbide material, which can make the pump run safely and continuously for more than 8000 hours.
8. The vertical sewage pump has strong flow capacity: the smooth large flow channel and the special anti-blocking design of the impeller ensure that the pump runs efficiently and without blockage.
9. The vertical sewage pump has double seals and double protection: the double mechanical seals are arranged in series to truly realize double protection and ensure the safety of the motor.
It is suitable for the discharge of heavily polluted wastewater from factories and businesses, sewage discharge stations in residential areas, drainage systems of urban sewage treatment plants, drainage stations of civil air defense systems, water supply equipment in waterworks, sewage discharge in hospitals and hotels, municipal engineering construction sites, exploration, mines Supporting auxiliary machines, rural biogas digesters, farmland irrigation and other industries, conveying sewage and sewage with particles, and can also be used for clean water and weakly corrosive media.
1. First check to see if the exterior fasteners have come loose in transit.
2. Check whether the power supply voltage meets the requirements on the motor.
3. Turn on the power for a trial run to see if the impeller rotates in the direction indicated on the pump. If the direction is reversed, just reverse any two-phase wires in the cable. The time for the trial run should not be too long to avoid burning the seal.
4. Install the pump and start it up. It is best to install the pump foot screws.
5. Non-clogging pipeline pumps and pipelines should have their own supports, and the weight of the pipeline should not act on the pump.
6. If the discharge pipeline of the sewage pump is equipped with a check valve, it should be installed outside the intermediate valve.
7. For the convenience of maintenance and safe use of the pipeline sewage pump, a regulating valve is installed on the inlet and outlet pipelines of the pump and a pressure gauge is installed near the pump outlet to ensure that the pump operates within the rated head and flow range, ensuring that the pump The normal operation of the pump improves the service life of the pump.
8. When installing the pipeline type sewage pump, the anchor bolts must be tightened to avoid the impact of vibration on the performance of the pump when starting.
9. In order not to cause the pump to bear the thermal deformation of the pipeline when the pipeline pump is transporting high-temperature liquid, the foot bolts of the pump base should not be fixed. When the pipeline system expands with heat and contracts with cold, the pump can move together with the pipeline.
