- Inspect mechanical transmission components: Check the transmission device (such as belts, gears, etc.) between the motor and the pump head for wear, looseness, or jamming. If the transmission components are damaged, replace or adjust them promptly. Ensure good contact between the pump head rollers and the pump tubing. Wear on the rollers or aging of the pump tubing may lead to insufficient friction, affecting torque transmission; worn parts need to be replaced.
- Select appropriate pump tubing: Select pump tubing of appropriate material and size based on the viscosity, density, and other characteristics of the pumped medium. High-viscosity media may require larger inner diameter or more flexible pump tubing to reduce conveying resistance. Check the pump tubing for aging, cracking, or deformation. Aged pump tubing has reduced elasticity, leading to weakened compression; it needs to be replaced promptly.
- Improve heat dissipation: Overheating of the motor can cause demagnetization of magnetic materials, reducing torque. Ensure unobstructed heat dissipation channels for the motor, regularly clean components such as the cooling fan and heat sink, and add cooling measures if necessary.
- Adjust motor speed or add a speed reducer: If the application allows, a speed reducer can be installed between the motor output shaft and the pump head to increase output torque by reducing the speed, thus meeting high torque requirements. If the above methods still cannot solve the problem, it is recommended to contact the motor or peristaltic pump manufacturer for professional testing and repair to determine if there is an internal motor fault or other complex issues.
