Release time：2018-11-23 source：Jinan Hengsi Shanda Instrument Co., Ltd. Browse：
Many operators who use hydraulic universal testing machines may have encountered the problem of high noise in the oil pump of the hydraulic universal testing machine. So what causes it? Let’s briefly analyze the reasons, mainly the following points:
1. There are loose places at each connection of the test engine oil pipe, causing air to enter the hydraulic system or the oil to be contaminated by impurities;
2. The coupling, gear or pulley of the hydraulic universal testing machine has too much coaxiality difference;
3. Severe wear of the cylinder or other parts are damaged;
4. When the hydraulic universal testing machine is working, the external vibration is too great, resulting in resonance;
5. The oil used in the hydraulic universal material testing machine has too high viscosity, or the oil inlet of the oil pump is blocked by impurities and dirt.
Jinan Hengsi Shanda Instrument Co., Ltd. reminds you to find the root cause and solve the problem in a timely manner when encountering any problems during operation. Also, you may encounter various problems in the process of operating spring test machines, electronic universal test machines, pressure test machines, etc. If you encounter any problems you don’t understand, you should consult relevant engineers, contact manufacturers, etc. in a timely manner.
