液压万能试验机在运作時间长了以后，会出現某些难题，例如油源热，下边就来对导致液压机拉伸试验机油源热的缘故开展剖析，液压机拉伸试验机长期应用后，液压传动系统一部分非常容易导致液压油发烫，下面带大家了解一下液压万能试验机油源热的三个原因。

Hydraulic universal testing machine will have some problems after a long time of operation, such as heat of oil source. The reason of heat of oil source of hydraulic universal testing machine will be analyzed below. After long-term application of hydraulic tensile testing machine, part of hydraulic transmission system is very easy to cause hot of hydraulic oil. Below, we will know three reasons of heat of oil source of hydraulic universal testing machine. This is the case.

一、安裝精密度差，例如，液压机拉伸试验机的液压油缸与滑轨不平行面。解决方案：安裝液压油缸时，应以滑轨为标准开展精确测量，以确保缸中心线和滑轨的平面度规定。

1. Installation precision is poor. For example, the hydraulic cylinder of the hydraulic press tension testing machine is not parallel to the slideway. Solution: When installing hydraulic cylinder, precise measurement should be carried out according to the standard of slide rail to ensure the flatness of cylinder center line and slide rail.

二、液压件的生产加工精密度和装配线品质欠佳。解决方案：确保拉伸试验机液压件的生产加工品质，不过关的元器件不可以装进系统软件应用。相对速度件的安裝精密度务必超过要求的技术标准。

2. The precision of production and processing of hydraulic parts and the quality of assembly line are not good. Solution: To ensure the production and processing quality of the hydraulic parts of the tension testing machine, but the relevant components can not be installed in the system software application. The installation precision of relative speed parts must exceed the required technical standards.

三、相对速度件润化欠佳。解决方案：改进相对速度件的润化标准，坚持不懈拉伸试验机的定期维护，发觉润化标准差，马上清除。

3. The relative speed parts are poorly moistened. Solution: Improve the wetting standard of relative speed parts, persevere in regular maintenance of tensile testing machine, find the standard deviation of wetting, and remove it immediately.
