Water Pump Knowledge: (1) Control Measures During Water Pump Operation

1, Equipment and facility defects

If the manufacturing and maintenance quality of the water pump or the electrical control equipment of the water pump is poor, the drainage efficiency of the water pump is low or even unable to discharge water, which may cause drowning accidents.

Control measures:

1. Choose new and efficient drainage equipment with advanced technology and good manufacturing quality.

2. Strengthen the maintenance and repair of drainage equipment, ensure that the repair quality meets the maintenance standard requirements, and ensure that the equipment in use meets the intact standard requirements.

2, Defective protection

If there is a lack of protective cover at the coupling part between the water pump and the motor, it may cause mechanical injury accidents such as hand and foot involvement during the operation of the water pump; Electrical control equipment for water pumps, such as transformers and high-voltage switches, if there is no protective fence or insufficient protection distance; It may cause personal electric shock accidents; If there is no protective fence in the water pump suction well, it may cause people to fall and cause drowning accidents.

Control measures:

Complete the protective facilities for various mechanical and electrical devices according to relevant requirements. Install protective covers at the coupling between the water pump and the motor, set up fences for high-voltage electrical equipment, and set up reliable protective barriers or covers for the water pump suction well.

3, Electrical hazards

Electric shock accidents may occur due to electrical equipment leakage in the pump room, personnel accidentally entering live spaces, or touching exposed live objects.

Control measures:

1. Ensure that the leakage protection device and grounding protection device are complete and reliable.

2. Install reliable barriers for exposed charged bodies.

4, Noise hazards

The main sources of noise in the pump room include mechanical vibration noise from the operation of the pump unit, electromagnetic noise from the pump motor and electrical control equipment, which may cause occupational diseases in the pump workers.

Control measures:

1. Select water pumps, motors, and electrical control equipment with low noise.

2. Install the water pump and motor according to the installation quality standards.

3. Timely repair water pumps, motors, and electrical control equipment.
