1. Constant-power electric heating cables are generally used for thermal insulation in special areas where there are explosive gases or other dangerous areas. Therefore, valve openings or flammable and explosive gas accumulation areas should be avoided during installation.

2. The heating wire at the beginning and end of the constant-power electric heating cable shall not collide with the conductive core wire and the metal shielding layer during the installation process.

3. The parallel constant-power electric heating cable must be sheared at the heating joint when shearing. It cannot be sheared at will, and the shearing length must exceed 3 meters.

4. The parallel constant power electric heating cable is composed of a heating section. Arbitrary shearing is not allowed. When shearing, it should be sheared in the heating section.

5. The constant-power electric heating cable is different from the self-limiting temperature electric heating cable and cannot be used overlappingly.

What are the common refrigerator defrosting heater inspection and maintenance methods

1. The fan motor in the freezing room is damaged, resulting in no circulating cold air, so that the upper box has a certain degree of coldness, and the lower box is not cold. Inspection method: cut off the fan motor winding value, if it is infinite, it means that the fan motor winding is damaged due to open circuit, and the fan motor winding needs to be replaced. 2. The frost layer on the evaporator is too thick due to the damage of the defrost heater, the superheated defrost insurance or the open circuit of the bimetal defrost thermostat, which blocks the gap between the warped sheets of the evaporator and cannot pass the cold air. Maintenance method: Check the status of defrost heater, superheat defrost insurance, bimetal defrost thermostat, and replace damaged components.

How to calculate the heating power of electric heater

1. Power during operation. Power - Heat loss in the system. All calculations should take into account the worst case: lowest ambient temperature, shortest operation, highest cycle operation, maximum weight of temperature heating medium (flowing medium as maximum flow). 2. Steps to calculate the heater power: According to the process, draw the heating process flow chart (does not involve the material form and specification). 3. Calculate the heat required for the process. Calculates the amount of heat and time required to start the system. Draw the heating process flow chart, consider the appropriate safety factor, and determine the total power of the heater. Determine the sheath material and power density of the heating element, determine the size and quantity of the heater, and determine the power supply and control system of the heater.
