电缆填料函
1.什么是填料函?
电缆填料函是一种高品质电缆的防爆附件,又被称为电缆接头、电缆固定头、格兰头、电缆锁头、电缆压盖等
1.填料函性能
阿依蒂尔填料函装在电缆端口与防爆电器设备的连接处,起引入电缆、固定位置达到密封、隔爆作用,具有隔爆性能优越、结构安全可靠、安装简单方便、防护等级高等优点。
2.填料函的应用
阿依蒂尔填料函广泛用于石油、化工等各种防爆场所,在海上平台、船舶的防爆场所尤其适用。
3.填料函分类
根据用途不同,阿依蒂尔电缆填料函可分为焊接式、铆接式、夹紧式、管式等多种形式,可用碳钢、黄铜、不锈钢或尼龙等材料制造;
4.填料函作用
填料函主要由填料,水封环,填料筒,填料压盖,水封管组成。
填料函的作用主要是为了封闭泵壳与泵轴之间的空隙,不让泵内的水流不流到外面来也不让外面的空气进入到泵内。
始终保持水泵内的真空!当泵轴与填料摩擦产生热量就要靠水封管住水到水封圈内使填料冷却!保持水泵的正常运行。
所以在水泵的运行巡回检查过程中对填料函的检查是特别要注意!在运行600个小时左右就要对填料进行更换。

this could result in material breakdown. Silicon seals are suitable for extended operating temperatures of -60 deg to +180 deg and should be used for low temperature applications as the seal performance can be maintained throughout the lifetime of the installation.

Armoured Cables require a gland that features a clamping mechanism to terminate the armour both mechanically and electrically. The gland will usually be required to provide ingress protection by sealing on the outer sheath and retention by clamping the armour.Typically, armoured cables feature an inner sheath that the gland may be required to seal on.

IMPACT RESISTANCE: The gland selected must maintain the integrity of the enclosure.For hazardous location equipment, the minimum impact resistance is usually 7 Nm. Special care should be taken when selecting Nylon glands as these often have reduced impact capabilities.

CABLE GLAND APPLICATION
What is a Cable Gland ?
STANDARD DEFINITION : “A device designed to permit the entry of a cable into electrical equipment and which provides sealing and retention. It may also provide other functions such as earthing ( or grounding ), bonding, insulation, strain relief,or a combination of these.”In addition to these a cable gland should maintain the overall integrity of the enclosure into which it is to be fitted.

Earthing, Bonding, Grounding, Continuity or Insulation : The gland may be required to provide electrical functions in conjunction with its basic function of sealing and retention.Earth tags ( lugs for HV application ) can be used to provide an electrical connection point to earth the cable gland, and by
