Regarding difficulties starting an MDP type mining wear-resistant self-balancing multi-stage pump, the root cause must first be identified, as this may involve several aspects of the equipment. Then, take corresponding solutions based on the specific reasons. Below are some suggestions and possible solutions.

I. Problem Diagnosis

1. Power Supply Issues: Check if the power supply is stable and if the voltage meets the pump's starting requirements.

2. Motor Issues: Check if the motor is damaged or aging, and if the windings are intact.

3. Load Issues: Check if the pump's load is excessive, such as blockages at the pump's inlet or outlet.

4. Control System Issues: Check if the control cabinet's wiring is correct and if the circuit is unobstructed.

II. Solutions

1. Power Supply Issue Resolution: Ensure the power supply is stable; repair any issues promptly. Also, ensure the voltage is within the pump's allowable operating range.

2. Motor Repair or Replacement: If the motor is damaged or aging, repair or replace it promptly. Simultaneously, check the motor windings; repair any damage.

3. Load Adjustment or Cleaning: If there are blockages at the pump's inlet or outlet, clear them. Simultaneously, check the pump's operating status and ensure that parameters such as flow rate and pressure are within the normal operating range.

4. Control System Repair: Check the control cabinet's wiring to ensure there are no loose connections or short circuits. Simultaneously, check the control system's operating status; repair any issues promptly.

III. Preventive Measures

1. Regularly Check Power Supply and Motor: Ensure the power supply is stable, regularly check the motor's operating status, and promptly identify and address any issues.

2. Maintain Load Balance: Regularly check the pump's load conditions and ensure that parameters such as flow rate and pressure are within the normal operating range.

3. Strengthen Maintenance: Regularly clean the pump's interior and exterior to maintain cleanliness. Simultaneously, regularly check and replace wearing parts.

4. Improve the Control System: Strengthen the control system's maintenance and repair to ensure its normal operation.

In summary, for difficulties starting an MDP type mining wear-resistant self-balancing multi-stage pump, inspections and repairs should be conducted from aspects such as the power supply, motor, load, and control system. Simultaneously, take preventive measures and strengthen the equipment's daily maintenance to extend its service life. If the above methods fail to resolve the issue, contact professional technicians for further inspection and repair.
