Vacuum-pressure oil changing device

Abstract

The invention relates to an oil changing device, in particular to a vacuum-pressure oil changing device, which consists of a new oil tank and a wasted lubricating oil tank. The new oil tank and the wasted lubricating oil tank are respectively connected with an air compressor via gas pipelines, the air compressor is electrically connected with a control plate, a vacuum generator is disposed on the pipeline for connecting the wasted lubricating oil tank with the air compressor, an oil outlet of the new oil tank is connected with an oil injection pipe, and an oil inlet of the wasted lubricating oil tank is connected with an oil drainage pipe. The vacuum-pressure oil changing device has the advantages that a vacuum or pressure environment is created by the aid of an air source, pipelines are connected with the oil changing device and a gearbox to form an integral pressure pipe, liquid flows so as to achieve purposes of oil adding and oil changing, namely, vacuum is realized by the aid of air compression, and a pressure increasing or pressure relieving principle is set. Accordingly, lubricating oil can be changed by personnel on a tower base.

Description

technical field [0001] The invention relates to an oil change device, in particular to a vacuum-pressure oil change device, which can be used in wind energy industry, chemical industry, or military government transportation equipment, etc. by changing the corresponding structural configuration combination according to different application fields. Applied in the field of wind energy, it can be used to replace the lubricating oil of the gearbox in the nacelle at the base of the tower; it can be used in the chemical industry to clean or add large oil storage or gas storage facilities; it can be used to replace the lubricating oil of large equipment and facilities in military industry and government transportation equipment. This text emphatically elaborates the superiority of the invention in terms of replacing lubricating oil for wind energy generator gearboxes in the field of wind energy. Background technique [0002] The process of replacing the lubricating oil of the gear ...

Problems solved by technology

The disadvantages of the traditional technology are as follows: the heavy lifting of new lubricating oil or the landing of waste lubricating oil makes the labor intensity of workers high, and only relying on the gravity of lubricating oil to discharge, the process takes a long time and wastes manpower. The whole oil change process takes 6-8 hours , when draining used lubricating oil and injecting new lubricating oil, the process of draining and injecting will cause splashing or spraying of lubricating oil

Increased cost of the entire repair and maintenance process
