相信大家都知道液压万能试验机是采用液压加荷,液压系统会出现油缸工作速度达不到规定值的情况,那么是什么原因造成的呢,济南试验机行家与大家分享,原因大致有八条。
I believe we all know hydraulic universal testing machine is using the hydraulic loading,hydraulic system will appear cylinder operating speed is not up to the specified value, so what is the cause of it, Ji'nan test machine experts to share with you, there are eight reasons.
一、活塞、活塞杆与缸盖之间同轴度差。
A, piston, piston rod and cylinder coaxial degree difference.
二、液压万能试验机使用不当,外载比预定值大。
Improper use of two, hydraulic universal testing machine, the load is greater than a predetermined value.
三、液压缸与工作台平行度差。
Three, the hydraulic cylinder and the table parallel to the poor.
四、内泄漏严重。
In four, the serious leakage.
五、密封件破损。
Five, the seal is broken.
六、活塞杆与导向套配合间隙小
Six, the piston rod and the guide sleeve with the gap is small
七、活塞移动时“别劲”,机械装配质量差。
Seven, the piston moves "don't mind", the poor quality of mechanical assembly.
八、有脏物进入液压万能试验机液压系统的滑动部位。
Eight, a sliding parts dirt into the hydraulic system of hydraulic universal testing machine.
