What to do when a high corrosion and wear resistant multistage pump has difficulty starting?

2025-05-09

Regarding difficulties starting a highly corrosion-resistant and wear-resistant multi-stage pump, this could be due to a variety of reasons. Below are some possible causes and corresponding solutions.

I. Power Supply Issues

1. Check if the power supply is connected and if the voltage is stable. Unstable power supply may prevent the motor from operating normally.

2. Ensure that the cables are undamaged and that the motor wiring is correct.

II. Pump Issues

1. Check if the pump rotor is stuck or blocked. If the pump rotor is obstructed, it will cause difficulty in starting. In this case, the pump rotor needs to be cleaned to ensure it is unobstructed.

2. Check if the pump bearings are severely worn. Severe wear will cause inflexible rotation and affect startup. Bearings need to be replaced in this case.

III. Liquid Medium Issues

If the medium is too viscous or contains a large amount of solid particles, it may cause difficulty in starting the pump. The medium needs to be properly treated, such as heating or filtering.

IV. Overload Protector Issues

If the overload protector is improperly set or damaged, it may also prevent the pump from starting. The overload protector's settings need to be checked and adjusted, or the damaged overload protector needs to be replaced.

V. Other Factors

1. Check if the ambient temperature is too low, causing the lubricating oil inside the pump to solidify. If this is the case, heating measures can be taken to raise the ambient temperature.

2. Check if there are any foreign objects blocking or mechanical failures inside the pump. If there are such problems, foreign objects need to be removed or mechanical failures repaired.

When troubleshooting difficulties starting a highly corrosion-resistant and wear-resistant multi-stage pump, it is recommended to check the causes one by one according to the above steps and take corresponding solutions. If the problem is complex or cannot be solved independently, it is recommended to seek professional technical support or repair services. Regular maintenance and upkeep are also very important to ensure the normal operation and service life of the pump.

In short, for problems with starting a highly corrosion-resistant and wear-resistant multi-stage pump, we need to investigate and repair from multiple aspects. Hopefully, the above solutions will help you solve the problem and ensure the normal operation of the pump.
