Oil tank of hydraulic machine

Abstract

The invention provides an oil tank of a hydraulic machine. With the oil tank, a filtering device and a radiating device are used for removing impurities and cooling for hydraulic oil to ensure stableoperation of the hydraulic machine; the filtering work of the hydraulic oil in a first filtering cylinder and a second filtering cylinder is sequentially completed through a driving device, the cleaning work of the first filtering cylinder is completed, the working strength is greatly reduced, the continuity and the high efficiency of the filtering work of the first filtering cylinder are guaranteed, and the influence on the filtering effect caused by the residue of the filtering impurities is avoided; automation and intelligentization of the filtering device are realized by utilizing a PLC, liquid level sensors and electromagnetic valves, so that cleaning and filtering are more convenient; a main branch pipe plays a shunting role, so that the hydraulic oil is preliminarily cooled in a first radiating pipe, and the heat loss of the hydraulic oil in the first radiating pipe is accelerated by combining water cooling with air cooling; and the hydraulic oil is secondarily cooled through cooling devices, the cooling time of the hydraulic oil in inner pipes is prolonged by utilizing inner and outer spiral structures of a second radiating pipe, and the cooling reliability is greatly improved.

AI Technical Summary

Problems solved by technology

As a general non-cut forming processing equipment, the hydraulic press uses the pressure of the liquid to transfer energy to complete various pressure processing. However, the existing hydraulic presses have the following problems: First, most of the failures of the hydraulic press are caused by hydraulic oil. It is caused by the medium mixed in the medium, so keeping the hydraulic oil clean is a necessary condition for the normal operation of the hydraulic machine, so it is necessary to set up a filter device to filter the hydraulic oil to remove the sundries in the hydraulic oil, but the filtering effect of the existing filter device is not good. Good, and it does not have the function of automatic cleaning; second, the temperature of the hydraulic oil will rise when the hydraulic machine is working. When the temperature of the hydraulic oil rises to a certain level, it will affect the working performance of the hydraulic machine. Therefore, it is necessary to dissipate heat from the hydraulic oil. The currently used There are air cooling and water cooling methods, but the cooling effect of these two methods is not ideal, the heat exchange is insufficient, and the cooling efficiency is low.
