Here are the daily maintenance methods for peristaltic pumps:
Tube Replacement
Regularly check the condition of the pump tube. As the pump tube is the key component in direct contact with the fluid and is prone to wear, it should be replaced in a timely manner when cracks, bulges, or significant wear are found. The specific replacement cycle depends on the usage frequency and working conditions of the peristaltic pump, generally ranging from several weeks to several months.
Cleaning
External Cleaning: Keep the exterior of the peristaltic pump clean and wipe it regularly with a damp cloth to remove dust, dirt, and any spilled substances on the surface. Avoid using corrosive cleaning agents to prevent damage to the pump casing.
Internal Cleaning: When the pump is used to transport viscous, easily - clogged, or contaminated media, it needs to be internally cleaned regularly. After shutting down the pump, rinse the pump tube and the flow passage with clean water or an appropriate cleaning solution. For stubborn stains, a mild acid - base solution can be used for cleaning, but it should be noted that the solution does not corrode the pump components. After cleaning, rinse thoroughly with clean water to remove any remaining cleaning solution.
Lubrication
The moving parts of the peristaltic pump, such as the drive shaft and bearings, need to be lubricated regularly to reduce friction and ensure smooth operation. Use high - quality lubricating oil or grease as recommended by the manufacturer, and add an appropriate amount of lubricant according to the specified cycle. Be careful not to over - lubricate to avoid oil leakage and contamination of the working environment.
Tightening of Components
Regularly check the tightness of each component of the peristaltic pump, including the connection of the pump head, the fixing bolts of the motor, and the clamping device of the pump tube. If any looseness is found, tighten it in a timely manner to prevent problems such as liquid leakage and abnormal vibration caused by component loosening.
Motor Maintenance
Keep the motor of the peristaltic pump in a good working condition. Avoid overloading the motor and ensure that the power supply voltage is stable. Regularly check the operating temperature of the motor. If the temperature is too high, check whether the ventilation is good or whether there is a problem with the motor itself. Clean the motor fan and the ventilation duct regularly to ensure good heat dissipation.
Storage
If the peristaltic pump is not used for a long time, it should be cleaned and dried before storage. Remove the pump tube and store it in a dry and ventilated place. Cover the pump body to prevent dust and foreign matter from entering. It is recommended to start the pump regularly during the storage period to prevent the components from rusting and sticking due to long - term non - use.
