请各位高手童鞋帮忙看看下面两段话的翻译是否有不妥之处，如有，还请帮忙指正，谢谢！
1.本实用新型公开了一种固定式原油洗舱机，包括本体，本体内设置的主轴，主轴的主传动部件，主轴的控制机构，叶轮，叶轮传动部件，通过传动装置与主轴连接的喷嘴，主轴的主传动部件包括主轴上套装的双头来回螺纹套，双头来回螺纹套的上半部分套装有连接套，下半部分套装有水平转动套，连接套上套装有上蜗轮和螺母块，水平转动套上套装有下蜗轮，上蜗轮和下蜗轮分别啮合上蜗杆和下蜗杆，下蜗杆的传动拨块与上蜗杆的单向传动拨杆连接，上蜗杆的单向传动调速摆杆与主轴的控制机构连接，主轴最下端的齿条传动装置与喷嘴连接，喷嘴包括喷嘴体，喷嘴头，喷嘴头内孔装入一套有两片成十字交叉定位的螺旋叶片。由于采用了双头来回螺纹套和平行双蜗轮能够较简便的实现主轴的转动和上下移动；喷嘴由于采用了两片成十字交叉定位的螺旋叶片，使得喷射液柱自身呈螺旋线形态，有利于增强清洗效果和保护船板。
译文：
The utility model discloses a fixed crude oil washing machine, which comprises a body, a principal axis arranged in the body, a master driver of the principal axis, a control mechanism of the principal axis, impellers, impeller drive parts, a nozzle connected with the principal axis through a driving device. The master driver of the principal axis comprises a double back and forth thread bushing sleeved on the principal axis. A connection sleeve which is sheathed with an upper worm wheel and nuts is sleevely arranged on the upper half of the double back and forth thread bushing, and a horizontal rotating sleeve which is sleeved with a lower worm wheel is asrranged on the lower half of the double back and forth thread bushing.The upper and lower worm wheels respectively are engaged with an upper worm and a lower worm. The drive shifting block of the lower worm is connected with one-way drive deflector rod of the upper worm, and one-way drive governor rocker of the upper worm is connected with the master control mechanism. The rack gearing of the lowest end of the principal axis is connected with the nozzle which comprises a nozzle body, a nozzle head, wherein a set of two decussation locating helical blades is putted in the inner hole of the nozzle head. Since the double back and forth thread bushing and horizontal rotating sleeve are used, the rotation and movement up and down of the principal axis can be simply achieved; since the two decussation locating helical blades are used, the nozzle makes the spraying liquid columns in themselves exhibit helix forms, which is helpful to enhance cleaning effect and protection of ship plates.
2、本实用新型公开了一种聚四氟乙烯瓷瓶，包括瓷瓶本体（４），瓷瓶本体（４）由聚四氟乙烯材料制成，沿瓷瓶本体（４）的轴向有一个孔，孔内装有一个用绝缘材料制成的强度较高的中心轴（１），瓷瓶本体（４）的两端各设有一个密封圈（３），密封圈（３）、中心轴（１）和瓷瓶本体（４）由密封套（２）固连在一起。这种瓷瓶主要适用于在那些污染比较严重的环境中使用，特别是在电气化铁路的接触网上使用。聚四氟乙烯不仅有良好的电绝缘特性，而且不粘附任何污物。本实用新型采用在瓷瓶的中轴上安装一根高强度绝缘棒，在瓷瓶的两端进行精密封闭的办法，既保留了这种瓷瓶的绝缘性能好，耐污染的特性，又提高了聚四氟乙烯瓷瓶的强度。
译文：
The utility model discloses a polytetrafluoroethylene porcelain bottle comprising a porcelain bottle body (4) made of polytetrafluoroethylene materials. Along an axial direction of the porcelain bottle body (4) is formed a hole in which a central axis (1) made of insulating materials, having a higher strength, is positioned. A sealing ring (3) is respectively arranged on each of the two ends of the porcelain bottle body (4). The sealing ring (3),the central axis (1) and the porcelain bottle body are fixedly connected together by a seal sleeve (2). The porcelain bottle is primarily suitable for use in such environments sufferring from serious pollution, especially for use in a contact system for electrified railway. The polytetrafluoroethylene not only has good electrical isolation properties, but also has no adhesion to any soil. The utility model uses a method for installing a high strength insulating rod on the central axis of the porcelain bottle to conduct precise closing on the two ends of the porcelain bottle, which not only retains good insulation properties and pollution-resistant characteristics, but also improves strength of polytetrafluoroethylene porcelain bottle. |
