1. How to Operat the Dredging Sand Suction Pump

1.1 Turn-On Procedure: Check the sand suction pump according to the following steps before starting.

(1) Proper Installation of a Marine Dredging Sand Suction Pump:

To ensure optimal performance and longevity of the marine dredging sand suction pump, follow these installation guidelines:

• Place the pump on a stable foundation capable of supporting its weight, ensuring firmness to eliminate vibration.
• Securely tighten all anchor bolts to maintain stability and prevent misalignment.
• Adhering to these guidelines will promote efficient and reliable operation, minimizing the risk of damage or premature failure.

(2) Installation of Pipeline Valve:

When installing a pipeline valve, observe the following steps:

• Provide a dedicated support frame for proper alignment and stability.
• Securely fasten the support frame to ensure firm support.
• Pay attention to the sealing point at the pump flange, avoiding over-tightening of connecting bolts to prevent damage.
• Following these steps will ensure effective support and integrity of the sealing point, ensuring reliable operation.

(3) Shaft Rotation Inspection:

During installation or maintenance, rotate the shaft by hand as per the specified direction.

• Check for any signs of friction, ensuring smooth rotation without resistance.
• Adjust impeller clearance if friction is detected, following manufacturer guidelines to maintain optimal performance and prevent damage.

(4) Motor Rotation Verification:

Before operating the pump, verify the motor rotation direction matches the arrow marked on the pump body.

• Reversing rotation is strictly prohibited to prevent reduced efficiency, internal damage, and safety hazards.

(5) Shaft Alignment:

Ensure precise alignment between the pump shaft and motor shaft in direct drive configuration.

• For belt transmission, ensure parallel alignment and adjust sheave position to prevent vibration and wear.

(6) Shaft Seal Inspection:

• Check shaft seal water level and adjust packing gland compression for appropriate tightness.
• Ensure shaft seal water pressure is 35KPa higher than pump outlet pressure.
• For pumps with mechanical seals, connect shaft seal water before starting the pump.
