What kind of cartridge heater can be called a high density cartridge heater?
High-density cartridge heater are a type of electric heating element. There are often ordinary cartridge heater on the market to impersonate high-density cartridge heater. Suwaie company will briefly introduce what kind of cartridge heater can be called high density cartridge heater.
1. Look at the heating time. Under the test voltage, the time for the cartridge heater to rise from the ambient temperature to the test temperature should not be greater than 15min.
2. Look at the deviation of the rated power. Under the condition of sufficient heating, the deviation of the rated power of the cartridge heater should not exceed the specified range.
3. Look at the insulation resistance. The cold insulation resistance of the cartridge heater should be not less than 50MΩ during factory inspection.
4. Look at the insulation compressive strength. The cartridge heater should be kept for 1min under the specified test conditions and test voltage without flashover and breakdown.
When purchasing a high-density cartridge heater, you may wish to test the above four aspects. If the test results are inconsistent with the above, you must consider whether the cartridge heater is a qualified high-density cartridge heater.
Stainless steel seamless processing and long life
Take the lead in adopting INCLOY special stainless steel seamless processing technology, so that the surface of the cartridge heater is free of seams and flaws, which minimizes the conditions and space for scale formation. Scale is not easy to generate, which makes the surface of the heating pipe smoother and more resistant to corrosion, and improves thermal efficiency Longer service life.
Durable high density magnesium rod
Ordinary magnesium rods have shorter support shafts, do not get sufficient support, and are prone to corrosion and fracture. The broken magnesium rod has no anticorrosive ability. The high-density magnesium rod is strengthened, and the grade is lengthened to make the magnesium rod more firmly support the length of the shaft, the density is once again solidified, and the anticorrosive effect is more significant.
