目前,各油田电脱水器的电极普遍采用多点螺纹吊杆或销轴吊杆调节机构.不仅调节与找平困难,而且调节操作需在设备中进行,通风、采光条件很差.因此,设计一种安全、可靠并能在设备外操作的电场间距调节机构就显得非常必要.本文介绍一种新型电场间距调节机构——双向螺旋调节机构. At present, the electrodes of the electric dehydrator in each oil field generally adopt a multi-threaded screwdriver or a pin-shaft boom adjusting mechanism, which not only has the problems of adjustment and leveling, but also needs to be adjusted in the equipment for ventilation and lighting. Therefore, It is very necessary to adjust the electric field distance safely and reliably and operate outside the equipment.This paper introduces a new type of electric field pitch adjusting mechanism - bidirectional spiral adjusting mechanism.
