Description
Technical Field
[0001] The utility model relates to the technical field of hardness testers, in particular to a pump cover finished product hardness tester. Background Art
[0002] The finished pump cover hardness tester is a special instrument used to measure the surface hardness of materials. There are generally two types of hardness testers: desktop testers and portable testers. Desktop testers are generally used in laboratories. They have a stable working platform and a high-precision measuring system. By using a desktop tester, the hardness of the material can be accurately measured, thus providing a strong basis for evaluating its quality and performance.
[0003] The existing finished pump cover tester simply sets up a downward pressure mechanism to test the pump cover. The pump cover is placed under the pressure mechanism. The pump cover will move when the downward pressure mechanism applies pressure. The movement of the pump cover will cause the accuracy of the measurement data and lead to deviations. The surface of the existing placement table is mostly a smooth plane. For the pump cover being tested, the stability effect is very important. In view of this, we provide a finished pump cover hardness tester. Utility Model Content
