Otro lote de bombas fue a su nuevo sitio. Esta semana, cargamos más de 20 conjuntos completos de Bombas de lechada de la serie AH de servicio pesado junto con Elec. Motores y accesorios, y estas bombas se enviarán a nuestro cliente en uno de los países de habla rusa.

Todas estas bombas de lechada están selladas por expansión. Y, de hecho, el sello de expulsor (anillo) se convierte en nuestro método estándar de sellado del eje. La mayoría de los clientes solicitan las razones. Esto se debe a que los expulsores se pueden aplicar en prácticamente todas las lloses, independientemente de la concentración sólida. Las bombas de suspensión fabricadas por CNSME son adecuadas para los sellos expulsores debido a la naturaleza abrasiva de la suspensión que se bombea, y la falta típica de agua de sello de glándulas fácilmente disponible, limpia y presurizada. El agua limpia a menudo puede ser difícil de obtener en molinos mineros y entornos de procesamiento de minerales, y el embalaje y las mangas pueden fallar rápidamente cuando las partículas abrasivas en el agua del sello o la lechada en sí misma ingresan a la caja de relleno. Pero esto no significa que no ofreceremos otras opciones de sellado de eje. El sello de glándula/embalaje y el sello mecánico también están disponibles para nuestras bombas de suspensión, si los clientes prefieren usar estos dos métodos de sellado.

During operation, there are four types of common failures of slurry pumps : corrosion and abrasion, mechanical failure, performance failure and shaft sealing failure. These four types of failures often affect each other.

For example, the corrosion and abrasion of the impeller will cause performance failure and mechanical failure, and the damage of the shaft seal will also cause performance failure and mechanical failure.

1. Bearings Overheated

A. Too much, too little or deterioration of lubricating grease/oil will cause the bearing to heat up, and the appropriate amount and quality of oil should be adjusted.

B. Check whether the pump -motor unit is concentric, adjust the pump and aglign it with the motor.

C. If the vibration is abnormal, check whether the rotor is balanced.

2. Reasons and solutions that may causenon output of slurry

A. There is still air in the suction pipe or pump, which should be filled with liquid to discharge the air.

B. The valves on the inlet and outlet pipeline are closed or the blind plate is not removed, then the valve should be opened and the blind plate removed.

C. The actual head is higher than the maximum head of the pump, a pump with higher head should be employed

D. The rotation direction of the impeller is wrong, so the rotation direction of the motor should be corrected.

E. The lifting height is too high, which should be lowered, and the pressure at the inlet should be increased.

F. The debris is blocked the pipe or the suction pipeline is small, the blockage should be removed and the pipe diameter should be enlarged.

G. The speed does not match, which should be adjusted to meet the requirements.

3. Reasons and solutions for insufficient flow and head

A. The impeller is damaged, replace it with a new impeller.

B. Too much damage to the sealing ring, replace the sealing ring.

C. The inlet and outlet valves are not fully opened, they should be fully opened.

D. The density of the medium does not meet the requirements of the pump, re-calculate it.

4. Reasons for serious seal leakage and solutions

A. Improper selection of sealing element materials, replace suitable elements.

B. Serious wear, replace the worn parts and adjust the spring pressure.

C. If the O-ring is damaged, replace the O-ring.

5. Reasons and solutions of motor overload

A. The pump and engine (output end of the motor or diesel engine) are not aligned, adjust the position so that the two are aligned.

B. The relative density of the medium becomes larger, change the operating conditions or replace the motor with suitable power.

C. Friction occurs in the rotating part, repair the friction part.

D. The resistance (such as pipeline friction loss) of the device is low, and the flow will become bigger than required. The drain valve should be closed to obtain the flow rate specified on the pump label.

Slurry pumps are primarily used in industrial sectors such as metallurgy, power generation, coal, and mining to transport slurries. These pumps handle mixtures containing solid particles, demanding that proper operating guidelines be followed.
To reduce the risk of clogging when processing slurries with high impurity content (e.g., mud), place a filter screen at the inlet. This minimizes the impurity particle entry, extends the pump’s lifespan, and prevents blockages. If a backup pump is available, alternate between pumps to avoid prolonged continuous operation.
Ensure the pump is placed on a stable surface during operation. For submersible slurry pumps, the pump structure has to be immersed in the water while the motor is above water to maintain stability.
For pumps with mechanical seals, always supply shaft seal water and never run them dry to prevent seal damage. Start the seal water before operation and continue supplying it for at least 3 minutes after shutdown.
In mining applications, slurry pumps often process rough ore, leading to significant wear. Lifespan varies based on ore hardness and particle size
