The reason why the pump speed of the horizontal slurry pump is too low

The horizontal slurry pump has become the most widely used impurity pump because of its simple structure, convenient use and maintenance, and high efficiency, but it is also troublesome because it sometimes cannot be lifted. There are many reasons why horizontal slurry pumps can't lift the slurry, one of which is because the pump speed is too low.

The reasons for the low speed of the water pump of the horizontal slurry pump include:

(1) Human factors. A considerable number of users are randomly equipped with another motor to drive the original motor, resulting in less flow, low lift or even water.

(2) The belt is worn. There are many large-sized off-water pumps that use belt transmission. Due to long-term use, the belt is worn and loose, and slippage occurs, which reduces the speed of the pump.

(3) Improper installation. The center distance between the two pulleys is too small or the two shafts are not parallel. The tight side of the transmission belt is mounted on the upper side, causing the wrap angle to be too small, the calculation of the diameter of the two pulleys and the eccentricity of the two shafts of the coupling drive are large, etc. The change in pump speed.

(4) Mechanical failure of the pump itself. The impeller and the pump shaft fastening nut are loose or the pump shaft is deformed and bent, causing the impeller to move more, directly rubbing against the pump body, or the bearing is damaged, which may reduce the rotation speed of the pump.

(5) The maintenance of the power machine is not recorded. The motor is de-excited due to the burning of the windings. The number of winding turns, the wire diameter, the wiring method change during maintenance, or the failure to completely eliminate the fault during maintenance will also cause the pump speed to change.

If the pump speed of the horizontal slurry pump is too low, the slurry will not be lifted up, which will affect the whole process and reduce the working efficiency. Keep in mind that the speed of the water pump of the horizontal slurry pump is too low, avoid unnecessary troubles, pay attention to maintenance, and ensure work efficiency.
