Description
技术领域 technical field
本实用新型涉及一种在三氯氢硅合成尾气处理系统——变压吸附装置中使用的WL-600W型真空泵的活塞杆刮油器，属于化工生产设备技术领域。 The utility model relates to a piston rod oil scraper of a WL-600W vacuum pump used in a trichlorosilane synthesis exhaust gas treatment system—a pressure swing adsorption device, belonging to the technical field of chemical production equipment.
背景技术 Background technique
WL-600W型立式活塞真空泵是三氯氢硅合成尾气处理系统——变压吸附装置中的关键设备，现有的立式活塞真空泵仅利用一个聚氨酯的密封圈对曲轴箱进行密封，由于密封圈很快就会磨损，致使润滑油随活塞杆的往复运动大量泄漏，既造成浪费，又污染了环境；而且时间一长，泄漏的润滑油还会通过填料进入气缸，造成气体的污染，更严重的是润滑油会与气体发生反应生成污垢，轻则影响真空泵的正常运行，重则引发设备事故。因此，目前急需开发一种经久耐用的活塞杆油封装置，保证生产的正常进行。 The WL-600W vertical piston vacuum pump is the key equipment in the trichlorosilane synthesis tail gas treatment system - the pressure swing adsorption device. The existing vertical piston vacuum pump only uses a polyurethane sealing ring to seal the crankcase. Due to the sealing The ring will soon wear out, causing a large amount of lubricating oil to leak with the reciprocating movement of the piston rod, which not only causes waste, but also pollutes the environment; Seriously, the lubricating oil will react with the gas to form dirt, which will affect the normal operation of the vacuum pump, and cause equipment accidents. Therefore, there is an urgent need to develop a durable piston rod oil seal device to ensure normal production.

具体实施方式 Detailed ways
参看图1，本实用新型主要包括刮油盒（由下刮油盒1和上刮油盒2对接而成）、压盖3、螺柱4、环状弹簧板5、刮油环6和拉簧7。刮油环6设置2～4个（图1中为3个），它们叠放在刮油盒内并套装在立式活塞真空泵的竖直活塞杆10上，每个刮油环6的上表面内侧设有环形油槽8，当真空泵活塞杆10上行时，上部刮油环6将活塞杆10上的润滑油刮到其下部刮油环6的油槽8内，油槽8内的润滑油从油槽8一侧的油道流入刮油盒的底部，再由刮油盒底部的回油孔9流入机箱。处于最下方的刮油环6可将油直接刮入机箱。 Referring to Fig. 1, the utility model mainly includes an oil scraping box (made by connecting the lower oil scraping box 1 and the upper oil scraping box 2), a gland 3, a stud 4, an annular spring plate 5, an oil scraping ring 6 and a pull Spring 7. There are 2 to 4 oil scraper rings 6 (3 in Fig. 1), they are stacked in the oil scraper box and fitted on the vertical piston rod 10 of the vertical piston vacuum pump, the upper surface of each oil scraper ring 6 There is an annular oil groove 8 on the inner side. When the piston rod 10 of the vacuum pump goes up, the upper oil scraper ring 6 scrapes the lubricating oil on the piston rod 10 into the oil groove 8 of the lower oil scraper ring 6, and the lubricating oil in the oil groove 8 flows from the oil groove 8 The oil passage on one side flows into the bottom of the oil scraper box, and then flows into the chassis through the oil return hole 9 at the bottom of the oil scraper box. The oil scraping ring 6 at the bottom can directly scrape the oil into the chassis.
为了加工方便，刮油盒采用分体式结构，下刮油盒1固定在真空泵的机体上，再由螺柱4和螺母将下刮油盒1、上刮油盒2和压盖3连接在一起。 For the convenience of processing, the oil scraping box adopts a split structure, the lower oil scraping box 1 is fixed on the body of the vacuum pump, and then the lower oil scraping box 1, the upper oil scraping box 2 and the gland 3 are connected together by studs 4 and nuts .
为了保证刮油环6与立式活塞真空泵的竖直活塞杆10紧密贴合，刮油环6也采用分体式结构，每个刮油环6由两个半环体拼成，两个半环体之间留有间隙，其外部由拉簧7箍紧。拉簧7是直径较小的螺旋弹簧，其两端对接后套在刮油环6的外部，保证刮油环6的两个半环体与活塞杆10紧密接触。 In order to ensure that the oil scraper ring 6 fits closely with the vertical piston rod 10 of the vertical piston vacuum pump, the oil scraper ring 6 also adopts a split structure. Each oil scraper ring 6 is composed of two half-rings, and the two half-rings There is a gap between the bodies, and the outside is tightened by extension spring 7. The extension spring 7 is a helical spring with a small diameter, and its two ends are butted and sleeved on the outside of the oil scraper ring 6 to ensure that the two half-rings of the oil scraper ring 6 are in close contact with the piston rod 10 .
整个刮油器组装完毕后，环状弹簧板5会有微小变形，其主要作用是靠本身的弹性压紧刮油环，此外还有一定的阻油作用。 After the whole oil wiper is assembled, the annular spring plate 5 will be slightly deformed, and its main function is to compress the oil scraper ring by its own elasticity, and also has a certain oil resistance effect.
