计算功率

Computing power

编辑 一、加热管的设计计算,一般按以下三步进行:

 editor, the design calculation of heating tube, generally in accordance with the following three steps:

1、计算从初始温度在规定的时间内加热至设定温度的所需要的功率

1, calculated from the initial heating temperature within the prescribed period of time to set the required power of the temperature

2、计算维持介质温度不变的前提下,实际所需要的维持温度的功率

2, maintain medium under the condition of constant temperature calculation, actual need to maintain the power of temperature

3、根据以上两种计算结果,选择加热器的型号和数量。总功率取以上二种功率的最大值并考虑1.2系数。

3, according to the above two kinds of calculation results, select the types and quantity of the heater. Total power to take over a maximum of two kinds of power and consider coefficient of 1.2.

公式:

Formula:

1、初始加热所需要的功率

1, the initial heating power that is needed

KW = ( C1M1△T + C2M2△T )÷ 864/P + P/2

KW = (C1M1 delta T + C2M2 delta T) present 864 / P + P / 2

式中:C1C2分别为容器和介质的比热(Kcal/Kg℃)

Type: C1C2 respectively containers and the specific heat of the medium (Kcal/Kg ℃)

M1M2分别为容器和介质的质量(Kg)

M1M2 respectively, the quality of the container and the medium (Kg)

△T为所需温度和初始温度之差(℃)

Delta T is required for the difference between the temperature and the initial temperature (℃)

式中:M3每小时所增加的介质kg/h

Type: in M3 per hour to increase media kg/h

3.加热管环境性能曲线

3. The heating pipe environmental performance curve

如何选择

How to choose

1、一般客户使用最多的就是不锈钢304材质。工作环境一般分为干烧与液体加热,如果说是干烧,比如用于烘箱,风道式加热器,可以采用碳钢材质、也可以采用不锈钢304材质。如果是加热液体的,若是水,就用不锈钢电热管,这个不锈钢一般是不锈钢304材质,若是油,可以用碳钢或者不锈钢304材质。若是带有弱酸碱性液体的,可以采用不锈钢316材质。若液体中才有强酸的,就应该采用不锈钢316、聚四氟乙烯甚至是钛管。

1, the general customers the most used is 304 stainless steel material. Work environment in general can be divided into dry and liquid heating, if dry, such as used in oven, duct heater, can use carbon steel material, also can use of 304 stainless steel material. If if is heating liquid, water, stainless steel heating tube, the stainless steel is generally 304 stainless steel material, and if the oil, can use 304 carbon steel or stainless steel material. If with weak acid alkali liquid, can use of 316 stainless steel material. If have a strong acid in the liquid, should adopt stainless steel, teflon, and even 316 titanium tube.

2、根据工作环境来确定加热管的功率。

2, according to the work environment to determine the power of heating tube.

功率的设定,主要就是干烧电热管与液体加热,干烧的话,一般一米长度的管子做1KW ,加热液体,一般是一米长度的管子做2-3KW,最大不的超过4KW。

Power set, the main dry and liquid heating, electric heating tube is dry, a meter in length of pipe do 1 kw, heating liquid, usually one meter length of pipe do 2-3 kw, maximum of not more than 4 kw.

3、根据客户的电热设备选用加热管的形状。

3, according to the customer’s electric heating equipment to choose the shape of the heating tube.

不锈钢加热管的形状千变万化,最简单的是直棒,U型再到异型。具体情况采用具体形状的电热管。

The shape of the stainless steel heating tube, straight rod, is the most simple u-shaped to aliens. Particular case USES the specific shape of electric heat pipe.

4、根据客户的加热管的使用情况来确定加热管的壁厚

4, according to the customer’s use of the heating tube to determine heating pipe wall thickness

加热管功率计算的性能曲线 一般加热管的壁厚都采用的是0.8mm,不过根据加热管的工作环境,比如水压大的情况下,需要采用壁厚厚点的无缝不锈钢管来制作电热管。

The performance of the heating tube power calculation curve General heating pipe wall thickness is 0.8 mm, but according to the heating pipe work environment, such as water pressure under the condition of big, need to adopt thick wall seamless stainless steel tube to make the electric heat pipe.

5、购买时候问清楚厂商,加热管制作的内部材质

5, when buying ask manufacturers, heating control of internal material

加热管为什么很多外观上相似,而价格会有很大的误差呢?那就是在于里面的内部材质,内部最重要的2种材质就是绝缘粉以及合金丝。绝缘粉,差的会用石英砂,好的会用到绝缘改性氧化镁粉。另外,合金丝,一般的用铁铬铝,根据管子制作的要求与档次,可以采用镍铬合金丝。正所谓,一分钱,一分货。建议广大客户,不要贪图便宜,以免购买劣质产品。

Heating pipe why many similar appearance, but the price will have a lot of error? That is the inner material is inside, two material is the most important internal insulation powder and alloy wire. Poor insulation powder, with quartz sand, good insulation modified magnesia powder may be used. In addition, the alloy wire, iron chromium aluminum, according to the requirement of the pipe production and class, nickel chromium alloy wire can be used. What is called, a penny, a minute goods. Advice to the masses of customers, do not covet is cheap, so as not to buy bad products.

破裂原因

Rupture reason

原因一:填粉的过程中,镁粉中混有杂质,经高温这些杂质将被碳化,使用长了就会出现管子炸裂现象;

Reason 1: the process of filling powder, magnesium powder mixed with impurity, high-temperature these impurities will be carbonized, use long pipe cracking phenomenon will occur;

原因二:选材很重要,不锈钢有很多种,根据加热管使用的环境选择正确的材料;管子本身也有区别一种是有缝管,一种是无逢管,有缝钢管是用钢带焊接成的 如果有一点焊的不到位就会管子炸裂,一般无逢管不会出现这种问题,有可能就是有缝管质导致的;

Reason two: selection is very important, there are many kinds of stainless steel, according to the environment of heating tube to use correct material; Pipe is itself is also has the difference between a tube, is a kind of seamless tube, seamed steel tube is welded with steel belt If you have a spot welding does not reach the designated position will be the pipe burst and generally seamless tube will not appear this kind of problem, is be tube caused by mass;

原因三:不锈钢电热管用于加热的液体也有区别,有些是腐蚀性液体,有些是水, 加热水有时候就是水质原因,因为很多可能多是用地下水,或者自来水,杂质较多,易结水垢,水垢太多太厚,会导致内部温度无法扩散,从而导致加热管爆管。如何有效的去除水垢,推荐阅读《推荐电热管水垢的解决方法》一文;

Three reasons: stainless steel heating tube is used for heating liquid also has difference, some of them are corrosive liquid, some water, heating water sometimes is why water quality, because a lot more is to use groundwater, or tap water, impurities, easy furring, scale too much too thick, can lead to internal temperature can’t spread, resulting in heat pipe explosion. How to remove scale, recommend reading the recommended solution of electric heat pipe scale;

原因四:加热管管壁太薄或者加热管功率设定过高,表面负荷太大,内部温度过高,容易引起加热管内部膨胀,从而导致加热管破裂。

Reason 4: heating tube wall is too thin or heating tube power set too high, the surface load is too large, the internal temperature is too high, easy to cause the heating tube expansion, resulting in heating tube rupture.

阻值确认

Resistance to confirm

加热管工作最重要的核心部分就是电热丝的工作,电热丝的好坏就决定了加热管的品质的优良。其研究电热丝就是研究电热丝的阻值阻值决定了电热管的功率。电热管的阻值是既定的,接不同的工作电压,出现不同电热管功率的效果,热效应也是如此。通常电阻越小,电阻丝的线径越大,电压固定的情况下,电阻丝通过的电流也就越大,当通过的电流超出电阻丝的负荷时容易发生断裂和损坏,数据表示加热管的电阻并不是越小越好,应该按照实际情况和保证正常使用选择合适的电阻丝。

Heating pipe is the most important core part of the work of electric wire, electric wire is decided by the quality of the fine quality of heating tube. The heating wire research is the study of heating wire resistance value determines the power of the electric heating tube. The resistance of electric heating tube is established, then the working voltage of different, the effect of different power electric heating tube, heating effect. Usually the smaller resistance, resistance wire, wire diameter, the greater the voltage under the condition of fixed, the greater the resistance wire by current, when more current through the load resistance wire is easy to break and damage, data showed the resistance of the heating tube is not as small as possible, should be in accordance with the actual situation and ensure the normal use of choosing appropriate resistance wire.

加热管阻值确认2点:

1、确定提供的额定电压与额定功率来确定出阻值。通过公式:电压*电压/功率=电阻。

1, provide the rated voltage and rated power to determine the resistance value. Through the formula: voltage * voltage/power = resistance.

2、电热丝的表面负荷是不可超标的,一般不可超过1.5w/cm²。

2, the surface of the heating wire load is overweight, generally not more than 1.5 w/cm&sup 2; .

在选择电热管阻值生产的时候,主要依据客户提供的额定电压与额定功率,同时,我们也要考虑电阻丝的表面负荷的承受能力。从而保障电热管的使用寿命。
