洛氏硬度计的维护、保养与注意

1、搬运硬度计时必须卸下砝码和压头，并在压头座与样品台之间夹防震胶垫;长途运输应恢复原有包装。

2、任何调试和检查，如装卸砝码、取下上盖、拔插电缆、打开侧门检查时，应切断电源。

3、禁止在压头与被测试样接触的状态下，切换试验力。

4、装卸压头应认真仔细，保证尖端无损伤、无污染，安装面清洁无异物。长期不用应卸下妥善保存，注意防锈。

5、样品台及标准硬度块表面应清洁无污染，无划痕、擦、碰伤保存时涂防锈油防锈。

6、测试时被测样品必须平稳放置，支承可靠，确保在测试过程中无任何位移、变形。

7、日常工作环境及关机后应注意防尘、防腐蚀介质。在一些较潮湿的地区，应经常注意防锈。

8、样品台升降丝杠应定期润滑。具体方法为:取下样品台及保护环，松开丝杠护套，向丝杠上注入数滴轻质润滑油，然后转动手轮，反复升降丝杠，使润滑油分布均匀。最后重新装好护套等物。注意润滑油不宜注入过多。

1, handling hardness time must be removed weight and pressure head, and in the pressure head seat and sample table clamp anti-shock rubber pad;  Original packing shall be restored for long distance transportation.  

2, any debugging and inspection, such as loading and unloading weights, remove the upper cover, unplug the cable, open the side door inspection, should be cut off the power supply.  

3. It is forbidden to switch the test force when the pressure head is in contact with the tested sample.  

4, loading and unloading pressure head should be careful, ensure no damage to the tip, no pollution, clean installation surface without foreign matter.  Long-term use should be removed and properly preserved, pay attention to rust prevention.  

5. The surface of sample table and standard hardness block should be clean and free from pollution, without scratches, scratches and scratches, and coated with anti-rust oil when preserved.  

6, the test sample must be placed smoothly, reliable support, to ensure that there is no displacement, deformation in the test process.  

7, daily work environment and shutdown should pay attention to dustproof, anti-corrosion medium.  In some humid areas, frequent attention should be paid to rust prevention.  

8, sample table lifting screw should be regularly lubricated.  The specific method is: take off the sample table and the protection ring, loosen the screw sheath, inject several drops of light lubricating oil into the lead screw, and then turn the handwheel, repeatedly lift the lead screw, so that the lubricating oil distribution is uniform.  Finally reinstall the sheath and other things.  Note that lubricating oil should not be injected too much.
