Product Specifications and Features of 50hz submersible pump

Key Components/Part

A submersible water pump is typically made up of the following components:

• Impeller: The pump’s main part that creates water flow by spinning and moving the water through the pump and out through the discharge pipe.
• Stages: Many submersible pumps have multistage impellers that increase water pressure and make it go deeper into the ground.
• Diffuser: A narrow flow passage that helps slow down water moving through the impeller.
• Seal: Submersible pumps have a mechanical seal that prevents water from entering the motor and damaging it. This seal is crucial in dirty water environments.
• Motor: Submersible pumps use Electric motors to spin the impeller. The motor is enclosed for protection.
• Pump casing: The pump casing holds all the parts together and protects them. It’s made of strong materials like stainless steel or cast iron.
• Electrical cord: This powers the motor. The cord needs to be durable so it doesn’t wear out in water or heat.

How to Install

The installation should be carried out carefully based on the manufacturer's recommendations.

• Preparing the site: Before installing the pump, the well casing needs to be disinfected and cleaned to remove any contaminants that might affect the water quality.
• Lowering the pump: Using a clean nylon rope or a stainless steel cable, carefully lower the connected electrical cable and water pipe assembly into the well. Ensure the pump sits at the specified depth.
• Connecting to power: The pump’s electrical cable should be connected to a power source. All the connections need to be waterproofed properly to prevent electrical malfunctions.
• Connecting the delivery pipe: Ensure the delivery pipe is connected to the pump and secure. The other end of the delivery pipe should be connected to a valve to prevent backflow.
• Priming the pump: Prepare a mixture of clean water and any required pump manufacturer-recommended, non-toxic silica sand. It should be circulated in the pump to avoid damage during dry running.
• Starting the system: Turn on the power supply to the pump. Allow the pump to draw water from the well and then deliver it through the delivery pipe.

Maintenance and Repair

• Regular Inspection: The inspection should be done frequently so that any wear or damage can be noted early. This prevents further issues from occurring down the road.
• Check the Electrical Cable: The submersible pump electrical cord should be checked occasionally for any signs of wear or damage. If there are any significant abrasions or cracks, ensure they are fixed to prevent failure.
• Water Quality Testing: The water where the pump is submerged needs to be tested frequently for contaminants. This ensures that the pump is not exposed to harmful elements that might affect its functionality.
• Vibration Monitoring: Monitor the operational vibrations coming from the pump. Any major changes in vibration levels may indicate mechanical failure or misalignment issues.
• Seal Inspection: Inspect and check the mechanical seal for signs of wear and tears that could cause water to infiltrate the motor. This is key in maintaining the pump’s internal elements.
• Heat Detection: Excessive heat in the motor indicates potential submersible pump failure. Just check the motor regularly and keep it from overheating during operation.
