1. No water by pumping liquid density and particle size is too high; plug flow; impeller to fault; bar pumped into the impeller is card; outlet pipe above the level of rated head height.
2. Inadequate flow, head low. The voltage is low, the impeller to the wrong or wear and tear, and the liquid is too heavy.
3. The insulation resistance is low, the surrounding environment is wet, the mechanical seal is serious leakage.
Non clogging pipeline sewage pump product features:
1. Pump and motor direct coupling, is a mechanical and electrical integration products, compact structure, stable performance.
2. Large flow channel anti blocking hydraulic components design, greatly improve the dirt through capacity, can effectively through the pump diameter of 5 times the fiber material and diameter of the pump diameter of about 50% of solid particles.
3. Reasonable design, reasonable matching motor, high efficiency, low noise, energy saving effect is significant.
4. Mechanical seal using hard wear-resistant tungsten carbide, durable, wear-resistant and other features, can make the pump safe and continuous operation for more than 8000 hours.
5. The pump for the vertical structure, import and export center line in the same level, and the same import and export flange specifications, installation and removal is very convenient.
6. Covers an area of small, no need to build a computer room, can save a lot of infrastructure costs; in the motor wind blade end with a protective cover, the whole machine can be placed in outdoor work.
