Description

一种IIC级防爆注油装置 技术领域
本发明是涉及一种IIC级防爆注油装置，属于润滑油加注技术领域。
背景技术
旋转设备是工业企业常用的设备，而作为旋转设备的关键部件-轴承，是保证旋转设备正常可靠工作的关键因素。由于轴承在持续高速旋转时，会因摩擦产生局部热变形，从而加速零件表面的磨损导致运转误差增大致使发生转轴报废。因此，为保证轴承安全可靠运转，避免轴承表面形成点蚀而造成失效，就要求对轴承进行良好润滑，因良好的润滑会对轴承的疲劳寿命和摩擦、磨损、温度、振动等有显著改善作用，分析轴承损坏的原因表明，40％左右的轴承损坏都与润滑不良有关。目前，为了保证轴承具有良好的润滑效果，需要在轴承运行一定时间(标准规定为1500-2000小时)后，要补充润滑油进行定期保养，以避免因润滑不良导致轴承损坏和安全事故。但目前实行润滑油的加注还是靠人工操作，一方面需要停机才能实现润滑油加注，对企业生产造成了不利影响；另一方面，人工保养方式还存在以下缺点：1、随意性强，不能按标准规定的时间进行定期保养；2、加注的油量多少不能精准确定，以致影响了润滑效果；3、耗费人力工时；尤其是，在一些易燃易爆的石油化工场所进行润滑油加注操作，还容易发生安全事故。

具体实施方式
以下结合附图和实施例对本发明的技术方案做进一步详细描述。
实施例
请结合图1和图2所示：本实施例提供的一种IIC级防爆注油装置，包括储油容器固定座1、防爆腔2、防爆走油通道3和活塞缸4及活塞组件5，所述防爆腔2是由上罩壳21与底座22采用隔爆接合面M1连接形成；防爆走油通道3设置在防爆腔2内，且上部与上罩壳21隔爆连接(即：采用隔爆接合面M2相连接)，下部与底座22隔爆连接(本实施例中，是通过在底座22上设螺纹孔221，在防爆走油通道3的下部设外螺纹，使防爆走油通道3的下部固定在螺纹孔221内，且两者之间采用隔爆螺纹W1连接)；防爆走油通道的进油口31与储油容器固定座的出油孔11相连通，防爆走油通道的出油口32与活塞缸的进油口41相连通；并且，构成活塞组件5的活塞杆51头部穿过底座22位于防爆腔2内，在活塞杆51上以隔爆螺纹W2连接有轴套6(即：轴套6内设有内螺纹，活塞杆51设有外螺纹，且两者之间的螺纹连接为隔爆螺纹W2连接)，在所述轴套6上套接有从动齿轮7，与所述从动齿轮7相啮合连接的主动齿轮8套接在电机9的输出轴91上，所述电机9固设在防爆腔2内(本实施例中，是通过在防爆腔2内设电机固定座92，所述电机固定座92固定在底座22上方)。
请再结合图1至图5所示：所述储油容器固定座1的中心设有用于与储油容器10螺纹连接的螺纹口12，在所述储油容器固定座1的底部中心设有圆锥头13，所述储油容器固定座的底部以所述圆锥头13为中心对称开设有多个扇形出油孔11(本实施例中示出了4个， 但不限定为4个)，所述圆锥头13的作用是在储油容器10与螺纹口12螺纹连接到位后，能刺破储油容器10的密封口，使润滑油能流出。为了进一步稳固储油容器10，可在螺纹口12的上方设置紧固组件14(本实施例中所述的紧固组件14是由两个弧形固定条141及固定耳142和紧固螺钉143组成)。为了保证注油顺畅，可在所述储油容器固定座1上设置空气呼吸器15，所述空气呼吸器15与防爆走油通道的进油口31相连通，以保证内外压相等。
另外，在上罩壳21的顶部设有导油槽211，所述导油槽211的底面与防爆走油通道的进油口31相连通，以利于收集从储油容器固定座1的出油孔11流出的润滑油并导入到防爆走油通道的进油口31中。本实施例中所述防爆走油通道3采用设有空腔的螺柱，既方便安装和加工，而且同时可用于加固上罩壳21与底座22之间的连接。
所述活塞缸4的下部设有定量注油腔42，所述定量注油腔42为圆柱形，且所述定量注油腔42的内径与活塞52的外径相适配，位于定量注油腔42上方的活塞缸内径大于活塞52的外径，从而保证活塞52的单次下压行程一定，被压出的润滑油量一定，从而达到定量加注的要求，使得加注计量方法非常简单且精确。为了避免润滑油中的杂质对轴承的影响，在所述活塞缸4的出油端还设有过滤网43和过滤网压紧盖44，以起到过滤作用。
所述轴套6的外部滑动连接有上铜套61和下铜套62，所述上铜套61固定在电机固定座92上，所述下铜套62固定在底座22上，且下铜套62与底座22的连接面为隔爆接合面M3，所述上铜套61和下铜套62的主要作用是防止轴套6的磨损。
图6示出了采用本发明所述的IIC级防爆注油装置进行注油的原理图，由图6可以看出：当需要加注润滑油101时，只需将待加注的储油容器10的口部与储油容器固定座1上的螺纹口12进行螺纹连接(作为优选方案，同时利用紧固组件14对储油容器10进行加固固定)；当储油容器10与螺纹口12螺纹连接到位后，储油容器10的密封口即将被设在储油容器固定座1底部中心的圆锥头13自动刺破，然后润滑油101将由开设在圆锥头13周侧的出油孔11流出，并汇集到导油槽211中，进而由防爆走油通道的进油口31流入进入活塞缸4中，当活塞缸4中储满油后，通过启动电机9带动主动齿轮8转动，因从动齿轮7与主动齿轮8相啮合连接，因此，在主动齿轮8转动时，可带动从动齿轮7的转动，而从动齿轮7是固定在轴套6上，因此可带动轴套6的转动，又由于轴套6与活塞杆51之间是螺纹连接，从而可通过轴套6的转动实现活塞杆51的升降运动，进而带动活塞52做上提或下压运动，实现润滑油的加注操作。
综上所述可见：本发明所提供的IIC级防爆注油装置，不仅可实现定量自动注油，而 且具有防爆功能，以及更换润滑油方便，可适用于各种场所、各种润滑油的在线加注，有利于实现旋转设备的自动保养；并且，所述的IIC级防爆注油装置还具有结构简单，使用方便等优点；因此，本发明相对于现有技术，具有显著进步性和工业实用价值。
最后有必要在此指出的是：以上所述仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
