What is the coefficient between the length of the tubular heater and the power?
I remember a customer asked me before, whether the longer the tubular heater is made, the better the quality. In fact, the answer is no, because there is a certain coefficient between the length of the tubular heater and the power. In addition, the ratio between the length of the tubular heater and the power is also different under different conditions (because the heating pipe sometimes has a cold zone, where the length refers to the length of the heating part of the heating pipe).
Let's take a look at the difference in the ratio of tubular heater length to power under different operating conditions.
1. When heating water, the ratio of tubular heater length to power is 2-3 (M / kW), that is to say, the power of one meter long heating pipe can reach 3KW
2. When heating oil, the ratio coefficient of tubular heater length to power is 1-2 (M / kW), that is to say, the power of one meter heating pipe can reach 1.5KW, and when the oil is relatively thin and the fluidity is particularly good, the power of heating zone of one meter of heating rod can reach 2kW
3. When the heating power of the air duct is 1.5KW, the heating ratio of 1.5KW can be achieved when the heating power of the air duct is 1.5KW.
The above is the most basic summary of the relationship between the length and power of the tubular heater. Of course, we will adjust the proportion relationship between them according to the needs of customers in some special use environment. Therefore, we can clearly tell the customer that the ratio of tube length to power is appropriate by comparing the above three environments. If the length of tubular heater is too long and the power is too small, the surface load of the electric tubular heater will be too low and the heating efficiency will be low, which will affect the normal use effect of the heating tube. If the length of the tubular heater is short and the power is large, the service life of the tubular heater will be affected.
