Problems solved by technology

As a result, frequent downtime accidents occur, and large manpower and material resources are required for maintenance and replacement, which increases production costs and reduces production efficiency
[0003] Therefore, there are phenomena such as oil pollution and oil quality degradation in the prior art, which are likely to cause the following problems: (1) the surface wear of sliding hydraulic components is aggravated, and the movement is blocked
(2) The holes of the orifice, damping hole, filter element and other components are blocked
(3) The hydraulic oil deteriorates and fails, and the working condition of the hydraulic system becomes worse

Abstract

The invention discloses a coal mining machine hydraulic oil quantitative analysis system. The system comprises a hydraulic system, and an oil analysis system connected with the hydraulic system. Multiple oil extraction points are arranged in the coal mining machine hydraulic system, firstly, at the oil extraction points, oil is collected into a coal mining machine oil collection center, and classifying and pretreatment are carried out, and oil flows to detection devices in a quantitative manner in fixed batches, through detection of eight items of 40 DEG C kinematic viscosity, water, open flash points, the total acid number, the spectral elemental analysis, the pollution degree, the direct reading iron spectrum and the iron spectrum wear analysis, oil analysis data of the oil extraction points can be obtained, finally, the oil analysis data are transmitted to a coal mining machine oil evaluation center, and the coal mining machine hydraulic oil comprehensive report is obtained; and thehydraulic oil quality is detected, the failure of the hydraulic system is prevented, and the coal mining production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mining machine oil product analysis, in particular to a coal mining machine hydraulic oil quantitative analysis system. Background technique [0002] With the continuous improvement of the automation of coal mining equipment in my country, the automatic drum shearer has become an important production equipment in the large mining height working face. Its high integration and large mining height range lead to high complexity of the electro-hydraulic control system. Oil quality requirements are strict. However, due to the harsh working environment of coal mining, the long-term operation of the coal shearer is likely to pollute the hydraulic oil of its electro-hydraulic system, which will eventually affect the stable operation of the equipment. According to statistics, more than 70% of hydraulic system failures are caused by hydraulic oil pollution and oil quality degradation. As a result, shutdown acc...
