Underfloor Heater Maintenance Method
Underfloor Heater maintenance method
In the process of industrial equipment, the Underfloor Heater is a highly demanding device, and when the gasket is damaged, the external drip is visible, and the heat exchanger, Underfloor Heaters, etc., begin to drip slightly. In the pressure of the larger impact of the process equipment may be due to damage to the seal and a greater leakage.
Even if the Underfloor Heater is used during the course of the year, there is a problem with the need for maintenance, especially its seal, to see if it is loose. This article will cover the precautions for Underfloor Heater maintenance.
Underfloor Heaters are an important part of the heat exchange technology in process industrial equipment. Elastic seals (see Table 1), which are sealed between panels, are a consumable and are also easy to use in natural conditions Aging parts. Its service life has an important effect on the service life of the Underfloor Heater. If these seals are thermally hardened, the original elasticity is lost and the Underfloor Heater can not function properly.
The following factors have an important impact on the life of the elastic gasket:
■ How the Underfloor Heater works (continuous or discontinuous)
■ Corrosion of heat dissipation medium and detergent used
■ Maximum operating temperature
■ Maximum working pressure
■ The stress of the elastic gasket is greater due to excessive pressure and unbalanced pressure
■ natural aging
The softening of the elastomeric gasket is related to the pressure and temperature. When the gasket loses its elasticity, the Underfloor Heater will drip. In some products, in order to solve the dripping caused by the aging of the gasket, the Underfloor Heater is allowed to be sealed Adjust the tension of the composite Underfloor Heater by adjusting the tightening force of the elastic gasket between the Underfloor Heaters. To solve the drip problem, on the nameplate of the Underfloor Heater with this function, Allows maximum and minimum stresses. For new Underfloor Heater panels, the minimum allowable stress should be used for connection fixation. Depending on the number of Underfloor Heater panels per group, the tightening force of the Underfloor Heater can be adjusted one or more times. Each time the screw is tightened, the nut can be screwed into 3mm and the stress of the tab is always observed during the tightening process, and only the Underfloor Heater with no working pressure is allowed to adjust the tightening force at room temperature.

In the process of industrial equipment, the Underfloor Heater is a highly demanding device, and when the gasket is damaged, the external drip is visible, and the heat exchanger, Underfloor Heaters, etc., begin to drip slightly. In the case of a large pressure in the process equipment, there may be a large leak due to the damage of the gasket. Under strong pressure shocks, the seal may sometimes leave the correct position of the Underfloor Heater. In this case, the equipment must be stopped immediately and the Underfloor Heater is allowed to cool to room temperature without pressure. If the gasket has been deformed under pressure, it can no longer be restored If you do not have a spare gasket, you must remove the heatsink on both sides of the damaged gasket from the entire Underfloor Heater group and then use the gasket on the remaining heatsink Check the stress and size of the Underfloor Heater group in consideration of the reassembled under the conditions of the stress and size of the Underfloor Heater group. The pressurized fastening must be carried out again. The remaining floor must be installed in strict accordance with the requirements in the operating instructions In order to ensure that the remaining Underfloor Heater has sufficient stress to resist the load, it is necessary to multiply the allowable stress of the original sheet by the number of the original Underfloor Heater. The resulting product is divided by the current Underfloor Heater The number of assembly stresses that each Underfloor Heater has to bear today.
