產品詳細介紹
Product details
一、直角引線單頭電熱管概述
A, right angle lead single head heating tube overview
直角引線單頭電熱管特點:安裝方便可靠。 用途:金屬模具或機器部件 電壓:12-440V 推薦規格:10︿16×100︿1000
Right angle lead single head heating tube features: convenient and reliable installation. Use: metal mold or machine parts voltage: 12-440V specification: 10 * 100 ^ 1000 ^ 16
二、直角引線單頭電熱管氧化鎂粉的選用
Two, the lead single head heating tube right selection of magnesium oxide powder
氧化鎂粉位于電阻絲和管壁之間,用于電阻絲與管壁之間的絕緣。同時,氧化鎂粉又具有良好的導熱性能。但是,氧化鎂粉又具有很強的吸濕性,因此在使用時要經過防潮處理(氧化鎂粉改性或電熱管封口處理)
Magnesium oxide powder is located between the resistance wire and tube wall, used for insulation between the resistance wire and tube wall. At the same time, magnesium oxide powder and has good thermal conductivity. However, magnesium oxide powder and has strong moisture absorption, so when in use after curing treatment (magnesium oxide powder modified or electric heating tube sealing treatment)
三、直角引線單頭電熱管的壽命
Life of single head electric heat pipe three, right angle lead
電熱管的壽命除了與電阻絲質量有關外,還與氧化鎂粉的質量,電阻絲直徑的選擇等因素有關。對于高溫電熱管,KAWAI能制造表面負荷在8W/CM2以下的電熱管。在選擇電阻絲的直徑時,需計算電阻絲的表面負荷以達到壽命要求。
Electric heating tube life in addition to the resistance wire quality, quality and magnesium oxide powder, the resistance wire diameter selection factors. For high temperature electric heating tube, KAWAI can make surface load in electric 8W/CM2 below the tube. In the selection of the resistance wire diameter, surface load calculation of the resistance wire to meet the life requirements.
四、直角引線單頭電熱管的環境條件
Four, right angle lead environmental conditions single head electric heat pipe
a.海拔高度不超過1000m
A. altitude does not exceed 1000M
b.周圍環境溫度-20~50℃
B. ambient temperature -20~50 ℃
c.周圍空氣相對濕度不大于90%(環境溫度為25℃時)
C. ambient air relative humidity of not more than 90% (an ambient temperature of 25 ℃)
d.周圍無導電塵埃、爆炸性氣體及能嚴重損壞金屬和絕緣材料的腐蝕性氣體
No conductive dust, D. around the explosive gas and serious damage to the metal and corrosive gas insulating material
e.沒有明顯的沖擊與振動
E. has no obvious impact and vibration
五、直角引線單頭電熱管開裂
Five, right angle lead single head heating tube cracking
(1)不銹鋼管焊縫質量特別差,抗拉強度太低;
(1) stainless steel pipe weld quality is poor, the tensile strength is too low;
(2)新管,烘干工序沒做好,氧化鎂內水分急劇受熱膨脹對管壁形成較大壓力。
(2) the new tube, drying process is not good, the moisture in the magnesium oxide has thermal expansion on the pipe wall pressure.
(3)在高濕度下長時間不使用,有較多濕氣入侵到管內。
(3) do not use at high humidity for long time, there is more moisture intrusion into the tube.
