Sludge pump is placed in the category of submersible centrifugal pumps. Using sludge pumps, sludge containing solid particles can be transferred to another environment. The sludge pump has a function similar to the floor pump, with the difference that it is able to pump liquids containing solid particles, fiber, solutes, etc. according to the technical specifications mentioned in the relevant catalog. What is a sludge pump? ?
In general, a pump is a device that is able to mechanically move fluids (gases and liquids) and is divided into three main groups based on the mechanism of moving fluids Direct lift pumps, displacement pumps and gravity pumps are divided. The sludge pump is a type of pump that is used for pumping and moving viscous fluids due to its high power. Before the invention of these pumps, dense fluids, wastes or fine solids mixed with water and other liquids in various industries were transported out of the structure by pipes, and due to the lack of sufficient pressure, disposal of these materials near the structure or sometimes even in There were places of passage, which created various challenges and problems. These pumps have the same performance as floor pumps.
How the sludge pump works
As it was said, sludge pumps are in the category of centrifugal pumps and their design is as follows. Pump impellers have backward curved blades and can be open or covered. Half-open propellers only have a back cover, and closed propellers are covered from the front and back, and finally, open propellers will not have any cover. Semi-open impellers are usually used in sludge pumps. In general, in these pumps, the electric motor drives the pump, and from the inlet part of the pump, the fluid containing fine or coarse solid particles enters the pump, and finally, with the rotation of the impeller, the speed of the fluid increases and it is directed towards the outlet. p>
The distance between the blades of the propeller will be enough for the solid materials to easily enter the pump and be destroyed by the liquid and not to block it. Also, for fluids containing large solids, propellers with fewer blades are used. The smaller the number of pump impellers or the greater the distance between them, the less likely it is to clog and block the pump, although these types of pumps are less efficient.
