高压柱塞泵曲轴密封面活动套
摘要：
高压柱塞泵曲轴密封面活动套是曲轴密封技术，它克服了目前技术存在的缺点，它是由活动密封套本体、固定螺丝孔、密封槽、固定边连接而成，在活动密封套本体的一侧连接着固定边，在活动密封套本体与固定边连接处的上下两端设置有固定螺丝孔；在活动密封套本体内、上下两个固定螺丝孔的中间设置有密封槽；本实用新型的意义是：根据曲轴密封面的结构点，将曲轴密封面由固定式改造为活动式，如果密封面损坏，就可以将坏密封面车去，装入活动密封套即可，活动密封套采用轴承钢耐磨性大大提高，并可以提高曲轴的使用寿命，不至于因为密封面损坏而造成曲轴报废。
摘要（英）：

The utility model discloses a crank shaft sealing face movable sleeve of a high-pressure plunger pump, and relates to the crank shaft sealing technology. The crank shaft sealing face movable sleeve overcomes the shortcomings in the prior art and is formed by a movable sealing sleeve body, fixed screw holes, a sealing groove and a fixed edge in a connected mode, the fixed edge is connected to one side of the movable sealing sleeve body, the fixed screw holes are formed in the upper end and the lower end of the connecting position of the movable sealing sleeve body and the fixed edge, and the sealing groove is formed in the movable sealing sleeve body and between the upper fixed screw hole and the lower fixed screw hole. The crank shaft sealing face movable sleeve has the advantages that a crank shaft sealing face is changed from the fixed type to the movable type according to the structural point of the crank shaft sealing face, and if the sealing face is damaged, the damaged sealing face can be removed in a turning mode, and then the movable sealing sleeve body can be installed. Bearing steel is adopted in the movable sealing sleeve body, the abrasive resistance is greatly improved, the service life of a crank shaft can be prolonged, and abandonment, caused by the fact that the sealing face is damaged, of the crank shaft cannot be caused.
