In the mechanical testing of building materials and metal materials, spring torsion testing machines have been widely used due to their excellent control performance and testing accuracy. In large steel enterprises and quality inspection unit laboratories, spring torsion testing machines often operate under high loads, and most testers lack experience in maintaining and maintaining the instruments, resulting in frequent problems. Some users even complain that the instruments have problems, but in fact, they are not, The spring torsion testing machine is a high-precision instrument that combines light, mechanics, and electricity. As long as we master some skills in using it, it is sufficient.
Here are a few explanations:
1. Complete the corresponding test with a suitable fixture, otherwise not only will the test not be ideal, but it will also damage the fixture:
Spring torsion testing machines are generally only equipped with fixtures for making standard specimens. If non-standard specimens are to be made, such as steel strands, lap steel precision, etc., corresponding fixtures must be added. In addition, some superhard materials, such as spring steel, must use special material clips, otherwise the fixtures will be damaged.
2. Cleaning and cleaning:
During the testing process, it is inevitable to generate some dust, such as oxide skin, metal debris, etc. If not cleaned in a timely manner, it will cause wear and scratches on the surface of certain parts. More seriously, if these dust enters the spring torsion testing machine system, it will cause serious consequences such as blocking valve holes and scratching the piston surface. Therefore, it is necessary to clean after each use.
3. Components should be regularly inspected:
All pressure control valves, pump regulators, and signal devices such as pressure relays, flow control valves, travel switches, and thermal relays should be regularly inspected.
4. The fasteners should be locked regularly:
The vibration of the sample after breaking often causes some fasteners to loosen. It is necessary to regularly inspect (normally used for about thirty working days) to avoid significant losses caused by loose fasteners.
5. The screw and transmission parts should be regularly coated with lubricating oil.
