Maintenance methods for explosion-proof electric heaters that are not used for a long time

As a technical professional explosion-proof electric heating equipment, explosion-proof electric heaters are widely used in industrial production, diagnosis and treatment, and other industries. It is necessary to carry out maintenance and upkeep of explosion-proof electric heaters on time. Generally, explosion-proof electric heaters are always used. If explosion-proof electric heaters are not used for a long time to prevent problems, the maintenance process of explosion-proof electric water heaters after long-term use is as follows:.

1. Open the inlet valve for water discharge application

If the explosion-proof electric heater is not used for a long time and needs to be reused, the inlet valve should be opened first to ensure that water is introduced into the simplified form and the working pressure does not exceed the pressure. Subsequently, the heater can be powered on;

2. Remove and replace the electric heating wire

3. Winter cold prevention solution

In winter, it is not necessary to use explosion-proof electric kettles. The water in the bucket should be immediately drained to prevent freezing and cracking, which may harm the next application;

4. Long term non application of power outage

If the explosion-proof electric heater is not used for a long time, the power switch and water resources should be turned off, and the pure water bucket should be filled to maintain the internal cleaning of the explosion-proof electric heater. The next application will be very easy to operate in practice; The power plug must be installed on the wire, and it cannot be inserted into the power socket. If the wire is brittle or damaged, it should be replaced immediately. Electric heaters without guidance systems installed cannot be used.
