Peristaltic pump outlet dripping liquid can be caused by several reasons, here is a list of some common causes and their solutions:
1.Loose or damaged tubing fittings:
Solution: Check and tighten all joints, and replace them in time if they are found to be damaged.
2.Worn or aged tubing:
Solution: Regularly check the wear and tear of the pump pipe, and replace the new pipe in time if it is found that the pump pipe is cracked, hardened or obviously worn.
3.Peristaltic pump pressure is set too high:
Solution: Adjust the pressure of the peristaltic pump to ensure that the pressure setting of the pump does not cause the tubing to be over-squeezed, which could lead to liquid leakage.
4.Return valve or check valve failure:
Solution: Inspect and repair or replace the return or check valve to ensure it is working properly.
5.Improper flow rate setting:
Solution: Adjust the flow rate settings to ensure that the flow rate matches the capacity of the line and tubing.
6.The pump head does not match the tubing:
Solution: Make sure you use the correct type and size of tubing that matches the pump head perfectly.
7.The pump tubing is not installed correctly:
Solution: Reinstall the tubing to ensure that the tubing is correctly positioned in the pump head and that the force is evenly applied at both ends.
8.Liquids contain gases:
Solution: Take degassing measures to ensure that there are no bubbles or excess gas in the liquid being conveyed.
9.The pump is working too long:
Solution: Regularly let the pump rest to avoid the problem of thermal expansion and contraction caused by continuous work for too long.
Solving these problems requires a careful examination of the individual components and settings of the peristaltic pump and adjustments to the specific situation. In routine maintenance, regularly checking and replacing the pump tubing, as well as ensuring that the connection is tight and correct, is an effective way to prevent liquid dripping. If the problem persists, refer to the operator's manual for your peristaltic pump or consult the manufacturer's technical support.
