Users to buy electricity with the tropics generally want to be able to use for a long time, as far as possible to reduce the frequency of replacement, but due to the long running time of the electric heating and aging, or pre design, installation and construction work caused by damage to the electricity with a certain proportion of the tropical, and batch update over the use of electricity with the tropical is also a normal phenomenon. In order to reduce the proportion of the electric heating cable caused by the outside world, the installation and maintenance of the electric heating cable should pay attention to the following problems:

Installation matters needing attention: whether there is a cross winding, or too dense spacing between the electric heating belt and the tropics, resulting in the over heat of the stack, which will affect the service life of the electric heating belt. In order to avoid this problem, in the design of the design should be accurate calculation of its winding spacing and the way to choose the most suitable installation of electric heating with tropical models;

Post maintenance personnel should record the installation sketch map and the relevant test data, archiving to prepare for the late maintenance, etc.;

It is necessary to pay attention to the safety and water resistance of the whole electric heating system. After the installation of the electric heating cable, it is necessary to make a layer of waterproof thermal insulation layer to ensure the electric heat tracing in the dry environment;

On the electricity with the tropical for regular maintenance, for easy damage to the site for key detection. General elbow is relatively easy to damage the electric heat with tropical places, can be detected by this. In addition relatively easy to damage the electricity with tropical parts as there are: the tank of the sewage department, the upper and lower tank between the combination of the Department, the liquid level gauge, flange and valve, the import and export parts of the instrument box. These are the places that need to pay attention to, can be used as the detection point.
