Nonwoven Meltblown Heater
It is an electric heating device mainly used to heat gas flow, commonly called air heater or gas heater. Its inner cavity is equipped with multiple baffles (guide plates) to guide the gas flow, extend the residence time of the gas in the cavity, thereby fully heating the gas, making the gas heating uniform, and improving heat exchange efficiency. The heating element uses stainless steel heating tubes, which are made by inserting electric heating wires into seamless steel tubes, filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, and then shrinking the tubes. When current passes through the low-temperature resistance wire, the generated heat is distributed to the outer surface of the heating tube through crystalline magnesium oxide powder, and then transferred to the heated gas to achieve the heating goal.
Process Features:
1. Fast heating and cooling speed, stable operation, smooth heating curve.
2. Adopts high-efficiency electric heater and temperature control method, high precision, small temperature error.
3. Has functions such as over-temperature alarm, dry-burn protection, pressure maintenance, long service life of the heater.
4. Good mechanical performance: Since its heating element is made of alloy material, under the impact of low-pressure gas flow, it has better mechanical performance and strength than any other heating element, which is more advantageous for systems and accessories that require long-term continuous gas heating.
5. Single unit power ranges from 2KW to 2000KW, customized as needed.
Precautions:
1. The operating part of the heater is a precision instrument. Handle with care during transportation,严禁 impact or collision.
2. The cylinder part should be properly lifted to avoid deformation and damage to the internal heating elements.
3. The heater and control cabinet should be stored indoors,严禁 rain exposure.
Heater Maintenance and Repair:
Fault 1: Digital display meter does not work. Check if the air switch is closed and if the control circuit is complete.
Fault 2: Heater temperature does not rise. Check if the fuse is intact and if the gas heater is damaged.
Fault 3: Three-phase imbalance. Check if the three-phase input voltage has phase loss. Open the air heater protective cover and use a multimeter to check if individual heating elements are open circuit.
