CIP Return Pump is the most widely used impurity pump due to its simple structure, easy use and maintenance, and high efficiency. However, it is also annoying because it sometimes fails to lift the slurry. There are many reasons why the horizontal slurry pump cannot lift the slurry, one of which is that the pump speed is too low.

The reasons why the horizontal slurry pump has a low pump speed include:
(1) Human factors. A considerable number of users randomly equip the original motor with another motor because the original motor is damaged, resulting in low flow, low head, or even no water pumping.
(2) Wear of the transmission belt. Many large water pumps use belt transmission. Due to long-term use, the transmission belt wears and becomes loose, causing slippage, thereby reducing the speed of the water pump.
(3) Improper installation. The center distance between the two pulleys is too small or the two shafts are not parallel, the transmission belt is installed on the top with a tight edge, resulting in a small wrap angle, errors in the calculation of the diameters of the two pulleys, and large eccentricity of the two shafts of the coupling drive pump, which will cause changes in the pump speed.
(4) Mechanical failure of the water pump itself. The impeller and pump shaft fastening nut is loose or the pump shaft is deformed and bent, causing the impeller to move more, directly rubbing against the pump body, or bearing damage, which may reduce the speed of the pump.
(5) The maintenance of the power machine is not recorded. The motor loses magnetism due to winding burnout. Changes in the number of winding turns, wire diameter, and wiring method during maintenance, or failure to completely eliminate the fault during maintenance will also cause the pump speed to change.

If the pump speed of a horizontal slurry pump is too low, the slurry cannot be lifted up, which in turn affects the progress of the entire work and reduces work efficiency. Remember the reasons why the pump speed of a horizontal slurry pump is too low, avoid unnecessary trouble, pay attention to maintenance, and ensure work efficiency.
