The basic structure of silicone rubber electric heating belt
Silicone rubber electric heating belt is divided into two types according to the use of the occasion: pipeline electric heating belt, air conditioning compressor crankcase electric heating belt. Its heating element is neatly arranged nickel-chromium alloy resistance wire, fast heating, uniform temperature, insulation layer using high and low temperature resistance, anti-corrosion, high insulation, aging resistant silicone rubber and fiber-free cloth, imported styrofoam and other materials, by lining, intermediate insulation layer, outer protective layer three layers, good heat resistance, reliable insulation performance, flexibility, can be in close contact with the heated object *, high thermal efficiency, easy to use, can be directly wound on the surface of the heated part.
First, the structural performance of pipeline electric heating belt
(1) The products are mainly composed of nickel-chromium alloy wire and insulation materials, which have fast heating, high thermal efficiency and long service life.
(2) Alkali-free glass fiber core frame winding heating wire, the main insulation is silicone rubber, good heat resistance, reliable insulation performance.
(3) The product has the softness of *, can be directly wound on the heated device, good contact, uniform heating.
Technical parameters of duct electric heating belt
Insulation material zui high heat resistance temperature: 250 °C
Recommended operating temperature: ‹200°C
Insulation resistance: >50MΩ
Compressive strength: 1500V/min
Power deviation: ±5%
The duct electric heating strip is a particularly soft fixed-length heating strip with a high design power density, so in addition to being used for heat tracing and insulation in general constant power bands, it can also be used in some cases where heating is required.
Precautions for the use of duct electric heating belt
(1) When installing, the silicone rubber plane side of the pipeline electric heating belt should be close to the surface of the medium pipeline and tank, and fixed with aluminum tape.
(2) In order to reduce heat loss, a double insulation layer should be added outside the electric heating belt of the pipeline.
(3) The pipeline electric heating belt is strictly forbidden to overlap and winding to prevent overheating damage.
Second, the function and function of the electric heating belt of the crankcase of the air conditioning compressor
1. Under the severe cold condition of the air conditioner, the transmission oil in the body will condense, which will affect the normal start of the unit. The electric heating belt of the crankcase of the air conditioning compressor can promote the heating of the oil and help the unit start normally.
2. Protect the compressor from damage in cold winter and prolong the service life. (In the cold winter, the oil in the machine condenses and agglomes, and hard friction will occur when opening and damage the compressor)
Product characteristics of electric heating strip of air conditioning compressor crankcase
1. Bend and wind at will according to the needs of the heated device, and the space occupies a small volume
2. Simple and fast installation
3. The heating element is covered with silica gel insulator
4. Tin copper braid has the effect of preventing mechanical damage and is also used for grounding
5. * Moisture-proof
5. It can be made according to the length of customer needs
6. Cold tail end of the core
