【技术实现步骤摘要】
一种储油罐车卸车用扫舱机构及包括该扫舱机构的抽油装置
本技术涉及卸油设备
,尤其涉及一种储油罐车卸车用扫舱机构及包括该扫舱机构的抽油装置。
技术介绍
在储油罐车卸车时,往往随着油品液位的降低,油泵入口具有的能量下降,当油品液位降至300mm时,液体装卸鹤管的抽吸口会在油品液面形成空气漩涡,如附图1所示,此时油品抽吸效率会大大降低,油品无法在抽吸力作用下通过油泵带动被输送到油罐中,这300mm的液位被称为“死区”,即不便于直接抽出的油品。对于航天用油来说,“死区”的油品重达3至4吨,价格高达2至3万元。目前,为了将储油罐车内的300mm“死区”油品全部抽出,往往需要将鹤管抽出后换成φ25的抽油管伸到储油罐车罐底继续抽吸,不但更换抽油管操作费时费力,且根据相关安全操作规程,当油罐进出油品后,30分钟内不允许人工检尺和采样等操作,以避免发生静电火灾,即将鹤管抽出后,需要等待30分钟后在经过人工检尺测量液位及采样达到标准后,才可将更换的φ25的抽油管放到储油罐车罐底内继续进行抽吸,将“死区”油品抽出,既费时又费力,使得整个储油罐车的卸车效率大大降低。因此,开发一种储油罐车卸车用扫舱机构及包括该扫舱机构的抽油装置,不但具有迫切的研究价值,也具有良好的经济效益和工业应用潜力,这正是本技术得以完成的动力所在和基础。
