Common fault analysis and treatment methods of silicone rubber heaters

Reason for blown fuse:

The diameter of the fuse is too small and the capacity is insufficient

2. Short circuit between power cord plug and socket

3. The plug or lead of the silicone rubber heater falls off, causing a short circuit

4. The silicone rubber performance heater (resistance wire) burns out or causes other short circuits

Dust or carbonization in the electric socket can cause a short circuit. The PI heating film adopts an improved PI film, which has better thermal conductivity and can be customized according to design requirements. It can meet different heating power and temperature requirements in different areas, achieving temperature distribution on the heating surface. The heating element of a 3D printer is stacked layer by layer to create a 3D model. Its operation process is similar to that of a traditional printer, except that traditional printers print ink onto paper to form a two-dimensional flat drawing, while 3D printers use liquid photosensitive resin materials, molten plastic fibers, gypsum powder and other materials to achieve layer by layer stacking and forming a 3D solid through spraying adhesives or extrusion. The silicone rubber heater is mainly composed of nickel chromium alloy heating wire and silicone rubber high-temperature insulation layer. The high-temperature insulation layer of silicone rubber is a thin sheet (with a standard thickness of 1.5mm) composed of silicone rubber and glass fiber cloth, and the silicone rubber heater has good flexibility.

Solution:

1. Replace the appropriate fuse

2. Repair or replace the power plug or socket

3. Re lock: Repair or replace

4. Clean dirt, repair or replace parts.

Reason for non heating:

1. Abnormal power supply or power outage

2. The fuse has blown

3. Poor contact between the power cord plug and the power socket or open circuit in the power cord wire

4. If the plug or lead of the silicone rubber heater falls off, it may cause other short circuits

5. Burn out the silicone rubber heater; The contact points of the temperature controller have not come into contact with social defects or melted and detached.

Solution:

1. After normal use of the power supply: replace the same type of fuse

2. Repair or replace

3. Re weld firmly

4. Replace the silicone heater with the same specifications; Repair or replace.

Reason for temperature controller malfunction:

1. The porcelain handle of the thermostat is stuck by a foreign object

2. Thermal bimetallic deformation; Fatigue and elastic losses of moving and stationary contacts

3. The dynamic and static contacts are stuck and cannot be opened or closed

4. The fastening screws of the moving and static contact parts are loose.

Solution:

1. Remove foreign objects and move up and down flexibly by pressing with your hand

Adjust the deformation amount to restore the original shape and elasticity

3. Adjust the angle of the touchpoints to restore psychological resilience

4. Grind the contact points, and if there is no legal effect, replace them with a newer product; Tighten again.

Reasons for leakage:

1. The grounding wire is not properly connected; Too much dirt on the electric socket or power plug

2. Circuit wire detachment and cup protrusion: Insulation damage to silicone rubber heater (silicone rubber heating strip)

III. The silicone rubber heater (silicone rubber heater) is burnt out and the cup body is short circuited

4. Improper cleaning and placement in the junction box.

Solution:

1. Connect the ground wire as required

2. After cleaning, air dry

3. Check for detachment and wires, and re weld them firmly

4. Repair or replace

5. Replace the silicone rubber heater with the same specification

6. Correctly change to clean and dry treatment.
