(ii) Matching the operating parameters of the hydraulic support
Pressure parameters
Hydraulic support is subject to different pressures when working, for high pressure system, the lubricant needs to have enough anti-wear performance and bearing capacity. For example, when the working pressure of the hydraulic support reaches more than 30MPa, the lubricant is required to maintain the integrity of the oil film under high pressure, so as to prevent the wear of metal parts in direct contact. At this point, the content and quality of the antiwear agent in the lubricant becomes particularly important.
Flow and flow rate parameters
Select the appropriate viscosity lubricant according to the flow and flow rate of the hydraulic support hydraulic system. If the flow and flow rate is large, in order to reduce the energy loss, generally choose a lower viscosity lubricant. However, the viscosity can not be too low, otherwise it can not form a thick enough oil film to protect the components. For example, in some hydraulic bracket systems with rapid frame removal, it is necessary to consider the flow rate and lubrication effect, and choose the lubricant with moderate viscosity to ensure the efficient operation of the hydraulic system and good lubrication of the components.
(III) Cost-benefit analysis
Price Comparison
Price comparison of different brands and specifications of hydraulic support lubricants. But not just price as the only criterion for selection, to combine the quality and performance of the lubricant. For example, some lower-priced lubricants may not be able to meet the long-term working requirements of the hydraulic bracket in terms of quality, which will lead to frequent replacement of lubricants and increase maintenance costs and downtime.
Service life and maintenance cost considerations
Selecting a good quality, long-life lubricant can reduce overall maintenance costs. Although the purchase price may be relatively high, in the long run, it can bring better economic benefits due to fewer lubricant changes and lower probability of equipment wear and repair. For example, a good quality hydraulic support lubricant can last more than a year, whereas a lower quality lubricant may need to be replaced every few months, and poor lubrication can lead to damage to hydraulic support components, increasing maintenance costs.
