The utility model relates to the technical field of construction machinery, in particular to a hydraulic oil tank, including a box body, wherein a cover body is arranged above the box body, the bottom of the box body is a conical surface protruding downward, and the lowest point of the conical surface at the bottom of the box body is provided with an oil outlet, and the side wall of the box body is provided with an oil suction port, and the top of the cover body is provided with an oil suction port. The oil return inlet is connected with the oil return filter located outside the oil tank and the oil return flow pipe located inside the oil tank. The oil return flow pipe is a double-layer straight pipe with an opening at the upper end. The upper end of the inner tube wall of the oil return flow pipe is provided with a plurality of through holes, and the lower end of the outer tube wall of the oil return flow pipe is provided with a plurality of through holes. There are several through holes. The hydraulic oil of the utility model flows from the oil return port into the inner tube of the oil return flow pipe, then overflows from the through hole at the upper end of the inner tube wall, flows into the outer tube, and finally flows into the oil tank from the through hole at the lower part of the outer tube wall, thereby increasing the circulation distance of the hydraulic oil, thereby effectively removing the air mixed in the hydraulic oil.

液压油箱
本技术涉及工程机械
,特别是涉及一种液压油箱。
技术介绍
液压油箱是液压系统中不可缺少的元件之一,其在液压系统中的主要作用是:1、贮存供系统循环所需的油液;2、散发系统工作时所产生的热量;3、释放混在油液中的气体;4、为系统中元件的安装提供位置。机械工作时,在液压泵的驱动下,液压油从液压油箱的吸油口处流出并通过液压油路驱动油缸、马达等液压元件工作,返回的液压油通过液压油箱的回油口回到液压油箱。因此,液压油箱内的液压油是循环流动的,循环流动的液压油就会混入空气,混入的空气在液压油流回液压油箱时产生气穴现象,进而损伤系统中的各液压元件。传统的液压油箱为了消除液压油箱中的气泡,通常使吸油口和回油口尽量相距远一些,并且在吸油口和回油口之间设置隔板,以增加液压油的循环距离,使液压油有足够的时间分离气泡。但是液压油箱的大小毕竟有限,从而吸油口和回油口的距离有限,有限的距离并不能使液压油中的气泡完全分离。
技术实现思路
本技术的目的在于针对现有技术的不足,而提供一种液压油箱,其解决了传统液压油箱油液循环距离短,不能使液压油有足够的时间分离气泡的问题。本技术解决其技术问题所采用的技术方案是:一种液压油箱,包括箱体,所述箱体上方设置有盖体,所述箱体底部为向下凸出的锥形面,所述箱体底部锥形面最低点设置有出油口,所述箱体侧壁设置有吸油口,所述盖体上方设置有回油口和进油口,所述回油口连接有位于油箱外部的回油过滤器和位于油箱内部的回油流通管,所述回油流通管为上端开口的双层直管,所述回油流通管的内层管壁上端设置有若干个通孔,所述回油流通管的外层管壁下端设置有若干个通孔。所述回 ...
