剪板机液压系统中的液压油油温升高原因：- 液压油在流动过程中在机器各部

<br>Reasons for the increase in the temperature of the hydraulic oil in the hydraulic system of the shears : <br>-The flow rate of the hydraulic oil is different in each part of the machine during the flow process- <br>There is a certain internal friction inside the hydraulic cylinder-There <br>is also friction between the hydraulic oil and the inner wall of the pipeline <br>These are the reasons for the increase in hydraulic oil temperature. An increase in temperature will increase internal and external leakage and reduce its mechanical efficiency. At the same time, due to the higher temperature, the hydraulic oil will expand, resulting in increased compressibility, and the control action cannot be transmitted well. Solution: Heat generation is an inherent feature of the hydraulic system, which cannot be eradicated and can only be reduced as much as possible. Use good quality hydraulic oil, avoid elbows in the layout of hydraulic pipelines, and use high-quality pipelines, pipe joints, hydraulic valves, etc.

The temperature of the hydraulic oil in the hydraulic system of the shearer is raised.<br>Reason:<br>- Hydraulic oil flows at different speeds at various parts of the machine during the flow.<br>- There is some internal friction inside the hydraulic cylinder.<br>- Friction is also present between the hydraulic oil and the inner wall of the line.<br>These are the causes of the increase in the temperature of the hydraulic oil. Higher temperatures will cause internal and external leaks to increase, reducing their mechanical efficiency. At the same time, due to the higher temperature, hydraulic oil will expand, resulting in increased compression, so that the control action can not be very good transmission. Solution: Fever is an inherent feature of the hydraulic system and cannot be eradicated and can only be minimized. The use of good quality hydraulic oil, hydraulic lines in the arrangement should try to avoid the appearance of elbows, the use of high-quality lines, as well as joints, hydraulic valves.

The increase of temperature will lead to the increase of internal and external leakage and reduce its mechanical efficiency. At the same time, due to the high temperature, the hydraulic oil will expand, leading to the increase of compressibility, so that the control action can not be well transmitted. Solution: heating is an inherent feature of the hydraulic system, which can not be eradicated and can only be reduced as far as possible. The use of high-quality hydraulic oil, hydraulic pipeline layout should try to avoid the appearance of elbows, the use of high-quality pipelines, pipe joints, hydraulic valves, etc.<br>
