How To Install Industrial Water Immersion Heater?
In the field of industrial electric heating equipment, industrial water immersion heater is a kind of heating element with high frequency. With their own high power advantages, industrial water immersion heater have been widely used. At the same time, industrial water immersion heater are generally used. Used to heat liquids, all are called immersion liquid heating element. So in industrial electric heating equipment, the installation method of flange electric heating pipe becomes a matter of concern to everyone. This problem needs to be considered in advance when we design the heating element, because the design of the heating element is different for different installation methods.
Choice of flange mounting and fixing method
1. Threaded fixation. (Threaded flange type electric heating element)
There are two ways to fix the thread. One is to perforate the container, and the female tooth ring is directly welded to the container, and the threaded flange heating element can be directly screwed on the tooth ring. The other is that the container is thicker. The material, perforation, the heating element pass through, the thread of the hexagonal big nut and the threaded heating element can be forbidden (with a sealing ring in the middle).
2. Cooperate with female flange connection (flat flange heating pipe)
After the user determines the parameters of the flange, configure the appropriate female flange, fix the flange and the female flange by bolts, and fix it with a gasket. For those with high sealing requirements, it can also be welded and sealed on the original basis. .
Installation direction of flange electric heating pipe
The installation direction of the flange electric heating pipe is generally horizontal installation with holes at the bottom of the side and vertical installation from top to bottom (or from bottom to top). For these two installation methods, we need to consider when designing the heating element. The design is mainly reflected in the confirmation of the cold zone and the heating zone of the heating element.
When installed vertically, when the water level in the vessel heated by the heating element is not full, part of the heating element is out of the water level. Since the power load of the heating element for heating the liquid medium is much greater than the power load of dry heating, the flange heating element It cannot be dried out of the water. Therefore, in the case of vertical installation, if the heating element cannot be kept immersed in water for heating, it is recommended that the user keep a part of the cold end (the size of the cold end is subject to the low water level), and the liquid level is good. Controller. When the side bottom is installed horizontally, the phenomenon of dry burning can almost be avoided. However, when installing horizontally, the length of the heating pipe needs to be considered. Due to various influences, the side of the horizontal installation has a small force area and a large unit force. Therefore, this problem must be properly considered when selecting the flange parameters.
