Description

Technical Field

[0001] The utility model relates to the technical field of lubrication devices, in particular to a lubrication oil station integrated device. Background Art

[0002] Lubricating oil stations play an important role in the operation of heavy equipment. They can be used to optimize the hydraulic oil circuits and lubricating oil circuits of equipment such as multi-cylinder cone crushers. This is because these equipment are in continuous high-speed operation and heavy-load work, and friction and wear between various components are inevitable. Lubricating oil stations ensure that various components inside the equipment can be fully lubricated by supplying and circulating lubricating oil, which plays a role in ensuring smooth operation of the equipment, reducing wear and extending the service life of the equipment.

[0003] In order to ensure that the cleanliness of the lubricating oil in the return oil meets the requirements, the commonly used method is to install a pipeline filter between the return oil pipeline and the return oil end of the oil station. This pipeline filter can effectively remove various impurities mixed in the lubricating oil, such as metal particles, dust, etc., thereby significantly improving the purity of the lubricating oil. In this way, not only can the normal operation of the equipment be guaranteed, but also the lubrication effect can be further improved, the wear of the equipment can be reduced, and its service life can be extended. However, this method also has some problems. In order to avoid the filter basket from clogging and affecting the return of the oil, the operator needs to regularly replace or clean the filter screen of the filter device. However, this replacement operation is quite troublesome, especially for traditional pipeline filters. When replacing the filter basket, it may be necessary to disassemble part or even all of the filter structure, which not only increases the complexity of the operation, but also leads to excessive downtime. Secondly, installing a filter device between the return oil pipeline and the return oil end of the oil station requires additional installation space. Utility Model Content
