Industrial pumps are one of the essential pieces of equipment in industrial production, and their operating status directly affects production efficiency and product quality. However, due to factors such as long operating hours and harsh working environments, industrial pumps inevitably experience various failures. This article will introduce common industrial pump failures and their corresponding solutions.

I. Common Failures

1. Insufficient flow: During the operation of the industrial pump, there may be unstable flow or a decrease in flow.

2. Leakage: The pump body is not sealed properly, leading to liquid leakage.

3. Noise and vibration: Abnormal noise and vibration occur during operation.

4. Overheating: The temperature of the pump body or motor is too high.

5. Unable to start: The pump cannot start or the current is too high when starting.

II. Solutions

1. Insufficient flow: First, check whether the pump's rotation direction is correct; an incorrect direction will lead to insufficient flow. Next, check for blockages in the pump's inlet and outlet, and clear the pipes. If there are foreign objects blocking the impeller flow path, they should also be cleared promptly. Additionally, check whether the pump's speed is appropriate and adjust it to increase flow.

2. Leakage: First, check whether the sealing device is intact; if it is damaged, it should be replaced promptly. Also, check for issues with the shaft seal, adjusting the shaft seal gap or replacing it if necessary. Furthermore, check whether the screws are loose, as this is an important point to check, and tighten any loose screws in a timely manner.

3. Noise and vibration: First, check whether the pump is installed correctly, such as whether the anchor bolts are tightened. Next, check whether the rotating parts of the pump are balanced, such as whether the impeller is eccentric. Check whether the bearings are severely worn or poorly lubricated, and replace the bearings or add lubricant as needed.

4. Overheating: First, check whether the pump's load is too high and adjust the flow to reduce the load. Next, check whether the bearings are damaged or poorly lubricated, and replace the bearings or add lubricant as necessary. Additionally, check whether there are any obstructions around the pump that affect heat dissipation, and clear any obstacles to improve heat dissipation.

5. Unable to start: First, check whether the power supply is functioning normally. Next, check whether the motor is damaged; if it is, replace the motor promptly. Check whether there are any sticking issues in the pump's rotating parts and clear any sticking areas to ensure smooth rotation.

In summary, resolving industrial pump failures requires analysis and handling based on specific situations. In actual operations, it is important to pay attention to safety, operate reasonably, and follow relevant regulations.
