Open type oil tank for preventing oil pump from sucking air in inclined swinging state

Abstract

The invention discloses an open type oil tank for preventing oil pump from sucking air in an inclined swinging state. The oil tank comprises an oil tank body, an oil suction area and an oil supply area are arranged in the oil tank body, the oil suction area is located in the center area, the oil supply area surrounds the outside of the oil suction area, an oil pump oil suction pipe is arranged inthe center of the oil suction area, a one-way oil inlet opened towards the oil suction area in a one-way mode is formed in the bottom of the oil suction area, and an oil outlet is formed in the bottomof the outer part of the oil tank body; the oil supply area comprises a first oil supply area, a second oil supply area, a third oil supply area and a fourth oil supply area; the first oil supply area, the second oil supply area, the third oil supply area and the fourth oil supply area are in communication with one another through bottom through holes and a top space; and the first oil supply area, the second oil supply area, the third oil supply area and the fourth oil supply area are located on the outer side of the oil suction area, surround the oil suction area and are in communication with the oil suction area through the one-way oil inlet and the top space. The open type oil tank is simple in structure, low in cost and reliable in performance.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery, and in particular relates to an open oil tank which prevents the oil pump from being sucked up in a tilted swing state. It is especially suitable for occasions that require high oil pressure and flow stability, and can be used to ensure stable oil suction by the oil pump under harsh sea conditions such as tilting and swaying hulls. Background technique [0002] The lubricating oil station of large marine equipment usually needs to continuously supply lubricating oil to the equipment during the operation of the equipment, and the unstable oil pressure or insufficient flow may cause damage to the equipment such as increased vibration, heat, noise, and fatigue. [0003] A typical fuel tank in a marine oil station is an open tank, which is mainly composed of a tank and its accessories. Its liquid level communicates with the atmosphere, which is conducive to rapid heat dissipation of the o...
