Introduction to the safety of chemical pump using electricity in winter

Chemical manufacturers must pay attention to the safety protection in the use of equipment in winter. The motor of chemical corrosion resistant pump is very common, and the safety of electricity in winter is particularly important. Electric shock accident is one of the more common accidents in construction operation. Such accidents are often caused by human negligence and illegal operation. In addition, the cold or freezing weather in winter and the humid air have an impact on the line, so the safe operation and precautions for winter use are introduced here.

1. Before the winter construction comes, the electrician should carry out a comprehensive inspection and maintenance of all mechanical equipment and cables at the construction site, and immediately remove the mechanical and electrical faults when found. In the windy, snowy and rainy weather, carefully check the temporary power facilities on the site, check whether the circuits, gate boxes, transformers and other unsafe hidden dangers such as deformation and leakage should be repaired and reinforced in time, and stop production immediately when there are serious hidden dangers. Immediately arrange to solve the problem to ensure the safe use of electricity.

2. The electrical equipment used in the construction site must be used in strict accordance with the system of "one machine, one brake, one box and one leakage", and the electric box door should be locked at any time. The installation of wires, lamp sockets and electrical equipment must be carried out by professional electricians, and it is strictly forbidden to pull and connect the lines indiscriminately. It is forbidden to hang wires at random and dry clothes on wires.

3. When using a power tool, the original plug of the power tool shall not be removed or replaced, and it is strictly forbidden to insert the cable wire directly into the power outlet without using the plug. Long-term unused and damp power tools should be used by professional electricians to measure whether the insulation resistance meets the requirements. Power tools should be used that have been tested by professional electricians and found that the shell and handle of the power tools are broken, the power cord is damaged, and the plug shall not be used when it is damaged. A special grounding line shall be set up for welding operation. The use of bare wire is strictly prohibited. Cable wires are broken in more than three places and shall not be put into use. 12 V safe voltage is used in all wet places.

4. when using power tools, you should first check whether the power supply has a leakage protector. Enough space and channels for 2 people to operate at the same time should be set aside around the distribution box and switch box, and no sundries should be piled up. The operating space set up at the edge of the foundation pit and the power box is insufficient, strengthen the power consumption management of the construction in winter, check the performance of the leakage switch every day, change it in time when there is something abnormal, and make a good record.

RISTER PUMPS warmly reminds you of all electrical mechanical equipment. Including the movement of power cords or the removal of electrical equipment, must be operated by an electrician. When the equipment used by all kinds of electricity users stops working, the switch in the switch box must be turned off and the switch box must be locked.
