Analysis of four common problems with pumps for sludge dewatering machines
- 2019-06-05-

1. The pump is running but the flow is too low
1. Check the pump body for cavitation, and adjust the inlet pressure of the compressed air. Reduce the running speed of the pump to adjust the viscosity and concentration of the liquid.
2. Check whether the valve ball is stuck. If the conveyed liquid does not match the material of the valve ball. The valve ball will expand. Please replace the ball and seat with a suitable material.
3. Please check if the inlet pipe is blocked.
2. The pneumatic diaphragm pump of the sludge dehydrator cannot be started or moves slowly
1. Check whether the filter, pressure regulating and lubricating device and the air inlet filter are blocked.
2. Check whether the air valve is stuck by impurities, please remove and clean the air valve, and check whether the piston in the air valve has scratches. If the surface of the piston is shiny and not black, it means that the piston and the "O" ring need to be replaced. Traces of injuries. If the surface of the piston is shiny and not black, it means that the piston and the "O" ring need to be replaced. Please replace with a new product
3. Check the spindle and the "O" ring for scratches, abrasion and flattening. If they are damaged, replace them.
3. Liquid leaks from the outlet of the gas chamber
1. Please check if the diaphragm is broken.
2. Check whether the diaphragm is correctly installed and locked.
Four, there are a lot of bubbles in the outlet liquid
1. Please check if the diaphragm is broken.
2. Check whether the pump body and pipeline leak.

The sludge dewatering machine adopts the organic combination of spiral pressure and dynamic and static rings to form a new separation technology integrating concentration and dehydration, which adds an advanced dewatering mode option to the field of environmental protection sewage treatment in my country. Energy-saving and water-saving: Due to the continuous movement of the dynamic and static rings, the self-cleaning effect of the cylinder body is achieved, and the filter gap is not easily blocked. It replaces the high-pressure washing of the old generation filter cloth and belt filter plate, which greatly saves industrial water (single unit 13,000 tons of water per year).
