液壓萬能試驗機在運作時間長了以后，會出現某些難題，例如油源熱，下邊就來對導致液壓機拉伸試驗機油源熱的緣故開展剖析，液壓機拉伸試驗機長期應用后，液壓傳動系統一部分非常容易導致液壓油發燙，下面帶大家了解一下液壓萬能試驗機油源熱的三個原因。

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，液壓機拉伸試驗機的液壓油缸與滑軌不平行面。解決方案：安裝液壓油缸時，應以滑軌為標準開展精確測量，以確保缸中心線和滑軌的平面度規定。

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、液壓件的生產加工精密度和裝配線品質欠佳。解決方案：確保拉伸試驗機液壓件的生產加工品質，不過關的元器件不可以裝進系統軟件應用。相對速度件的安裝精密度務必超過要求的技術標準。

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、相對速度件潤化欠佳。解決方案：改進相對速度件的潤化標準，堅持不懈拉伸試驗機的定期維護，發覺潤化標準差，馬上清除。

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.
