Integrated type hydraulic headstock gear total closed oil tank

Abstract

The invention relates to an oil cylinder of a hydraulic system, in particular to a fully sealed oil cylinder of an integrated hydraulic hoister. The fully sealed oil cylinder comprises a fully sealed oil storage tank internally provided with a soft leather bag and an oil absorption port connector, an oil returning port connector, an oil filling port connector and an air bag connector are arranged on the tank. The fully sealed oil cylinder of the integrated hydraulic hoister has large oil storage capacity and can be installed in all directions without oil leakage; the oil fluid is separated from the external air so that no oxidation and pollution of oil fluid by the external environment are guaranteed and the oil fluid has high cleanness so as to ensure the safe and reliable work of the integrated hydraulic hoister; during the debugging, the oil cylinder can meet the debugging working condition of gradual oil filling and air exhaust; also the oil cylinder of the invention can guarantee the integrated hydraulic hoister to adapt to different climates and work normally no matter in the south or the north or in summer or in winter.

Description

technical field [0001] The invention relates to an oil tank of a hydraulic system, in particular to a fully enclosed oil tank of an integrated hydraulic hoist. Background technique [0002] The oil tank is a necessary part of the hydraulic system. Its function is not only to store oil, but also to dissipate heat, separate air bubbles in the oil, and precipitate impurities in the oil. [0003] Common fuel tanks fall into two categories: [0004] 1. Open oil tank, its liquid level is connected with the atmosphere, the hydraulic oil in the tank is drawn out or returned and the oil temperature changes, the oil volume often changes, so the air volume above the oil in the tank will also change, causing air In and out. In order to prevent dust and impurities from being brought into the outside air and keep the oil clean, an air filter (breathing port) is often installed on the cover of the open fuel tank. The air filter includes a filter screen and a desiccant to filter dust and...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is: to solve the technical problem that the fuel tank of the existing integrated hydraulic hoist cannot be installed in any direction. The present invention provides a fully enclosed fuel tank of the integrated hydraulic hoist, which can be installed in any direction. There is no oil outflow, and the oil is isolated from the outside air to ensure that the oil is not oxidized and polluted by the outside world
