Precautions for Stainless Steel Submersible Pumps

 

Due to the special nature of its manufacturing materials, stainless steel submersible pumps have the characteristics of corrosion resistance, high temperature resistance, environmental protection, large flow rate, and durability. In order to ensure their safe use, today we will introduce the precautions when using stainless steel submersible pumps:
1. Before using a stainless steel submersible pump, check whether the cables are damaged. When handling and installing the pump, cut off the iron parts to pull or damage the cables to avoid accidents caused by cable breakage and water leakage. If the cable is severely broken, replace it immediately and use a megohmmeter to check whether the insulation resistance of the electric pump is normal (the insulation resistance should not be less than 1 megohm).

2. Identify the grounding wire (usually yellow green) and connect it according to the prescribed procedure.

3. Choose appropriate stainless steel submersible pump protectors (such as leakage protectors, air switches, phase failure overcurrent protectors, etc.), and do not connect them directly with knife switches.

 

 

4. Connect the power cord according to the standard, test the power supply, check if the stainless steel submersible pump is running normally, and determine if the steering is correct. If the steering is incorrect, switch any two of the three power cords (note that the running time should not exceed half a minute).

5. Install the water outlet connector and water outlet hose (or iron pipe), tie a rope to the handle of the electric pump (the rope cannot be used as a substitute for the hanging rope), place the electric pump into the pump to be pumped, and turn on the power before use.

6. To ensure personal safety, it is strictly prohibited to install drainage operations (such as moving or inspecting, troubleshooting) and contact with electric pumps near them to prevent leakage and accidents.

7. It is strictly prohibited to expose the electric pump to water for a long (or short) period of time. The "on" and "off" of the electric pump should not be too frequent to avoid motor overheating and damage.

8. Long term pumping of liquids with high sand content can cause significant wear and tear on the flow components of stainless steel submersible pumps. Therefore, it is recommended to use stainless steel submersible pumps with sewage and sewage in a vortex shape.

 

Conditions for emergency shutdown of submersible pumps

 

1. Submersible pump odor, shaft seal oil leakage, bearing temperature exceeding 75 degrees, etc.

If the startup time is too long, the current will not return.

3. The ammeter reading of the motor is abnormal (too large or too small), and the system emits abnormal noise.

4. The outlet pressure gauge shows abnormal readings, and the submersible pump body vibrates greatly, producing abnormal noise, resulting in a serious decline in performance.

5. The cooling water or oil temperature of the submersible pump rises sharply, which is dangerous and requires emergency shutdown.

 

 

Although emergency parking may have some adverse effects on submersible pumps, allowing the equipment to continue operating under abnormal conditions can cause greater harm. Therefore, we hope that users can actively reduce equipment damage when encountering the above situations.
