Troubleshooting air heater users should consider the use of the air heater, the process we usually use has not considered the issues related to air heater common faults it? To know only learned of this knowledge we can be more rational applied to the air heater, for today we will explain to you the focus of knowledge in this regard, as follows: fault repair fault: DRO is not working. Check that the air switch is closed, explosion-proof water heater, the control loop is intact. Failure II: heater temperature does not rise. Check the fuse is intact, the air heater is damaged; Failure three: Unbalanced. 1. Check the three-phase line voltage phase. 2, open the air heater guard, hot water heater machine manufacturers, use a multimeter to check whether a single heating element circuit. The final temperature of the air heater air T2 progress, since air viscosity add, gas Reynolds number is reduced so that the convection heat transfer intensity decreased, low temperature hot water heaters, together with the surface temperature rise of the air heater heating element, heat plumbing fan, so that heat loss to add, and then dropped by the power of the heat exchanger. When T2 progress is too large, the appearance of the temperature of the heating element will be greatly increased, resulting in general electric heating elements can not accept, so T2 was bound to add general air heater heating elements heat the information function. gs-type hot water heaters, hot water heaters, steam heaters machine provided by the Texas Huaxin air-conditioning plant.
