The tripping fault of the slurry pump may be caused by the following reasons:
1. Unstable power supply voltage: High or low power supply voltage can have adverse effects on the motor and even cause tripping.
2. Motor overload: During the use of the slurry pump, if the motor load is too large, it will cause the motor to overheat, leading to tripping. Overload may be caused by factors such as excessive viscosity of the conveying medium or high conveying concentration.
3. Motor damage: If the motor malfunctions, such as winding burnout, rotor jamming, or excessive current, it can cause tripping.
The following solutions can be taken:
To address the issue of unstable power supply voltage, it is necessary to check and stabilize the power supply voltage within a reasonable range.
Regarding the issue of motor overload, it is necessary to check the usage of the slurry pump. If the viscosity of the conveying medium is too high or the conveying concentration is too high, corresponding measures need to be taken, such as replacing the pump body or adjusting the process flow.
3. Regarding the issue of motor damage, it is necessary to check the operation of the motor. If any faults are found, the motor needs to be repaired or replaced in a timely manner.
In addition, if the tripping is caused by excessive motor load current, it can be attempted to increase the current protection upper limit to solve the problem of automatic tripping. If the device is temporarily too high due to long-term shutdown, the air inlet can be closed to heat the pump body. If the motor is connected to a two-phase power supply and the three-phase power supply is not enabled, the three-phase power supply needs to be connected. If there are still tripping, disconnection and other situations after running for about ten hours, it is still necessary to adjust the overcurrent upper limit. If foreign objects or impurities are sucked into the exhaust port causing tripping, it is necessary to disassemble and inspect for internal faults before cleaning.
4. Check if the pump body is damaged: If the pump body of the slurry pump is damaged, it may cause the motor to overload, resulting in tripping. Therefore, it is necessary to regularly check the operation of the pump body, promptly identify and repair problems.
5. Replace the appropriate motor: If the motor power does not match the requirements of the slurry pump, it may cause tripping. Therefore, it is necessary to select a suitable motor based on the operational requirements of the slurry pump.
6. Regular maintenance and upkeep: The slurry pump requires regular maintenance and upkeep, including replacing vulnerable parts, cleaning impellers, bearings, and other components. This can ensure the normal operation of the slurry pump and avoid faults such as tripping.
7. Installation of protective devices: Protective devices such as thermal relays, current protectors, etc. can be installed on the slurry pump to prevent tripping faults caused by motor overheating or overload.
It should be noted that the above solutions need to be selected and implemented according to the actual situation. When dealing with the tripping fault of the slurry pump, it is recommended to stop the machine in a timely manner for inspection and ask professional personnel for maintenance to avoid the fault expanding or damaging the equipment.
