Low pumping test is a test method used to evaluate the performance of a material or structure under low impact loads. According to different application requirements, the requirements of low pumping test may vary, but generally include the following aspects:
1. Impact load: Low pump impact tests require low speed impact conditions, usually using electric or hydraulically driven impact devices to provide the impact load. The size, duration and waveform of the impact load should be determined according to the specific application requirements.
2. Impact sample: Impact sample should be representative and meet the actual conditions of use. The size, shape and material of the sample shall be determined according to the test requirements and shall meet the corresponding standards or specifications. 3. Test environment: Low pumping test should be carried out under appropriate environmental conditions, including temperature, humidity and air pressure and other factors. The test environment shall meet the requirements of relevant standards or specifications.
4. Test equipment: The equipment required for low pumping test includes impact device, acquisition system and control system. These devices should be able to provide accurate and reliable test data and meet the requirements of the corresponding standards or specifications. 5. Test method: The specific method of low pumping test should be determined according to the test standard or specification. The test method should include sample preparation, setting of test conditions, application of impact load, data acquisition and analysis.
In short, the requirements of low pumping test include impact load, impact sample, test environment, test equipment and test methods, etc. These requirements should be determined according to the specific application requirements and relevant standards or specifications.
Low pumping test is a test method to test the durability of concrete, which is mainly used to evaluate the performance of concrete under low speed impact loads.
In the low pumping test, the size of the concrete specimen is required to be a certain size, such as 300mm×300mm×500mm. In addition, it is necessary to apply a protective layer to the surface of the concrete specimen to prevent damage to the specimen. In the course of the test, it is necessary to place the concrete specimen on the impact table and apply a certain impact load. By observing and recording the deformation of concrete specimens, the durability of concrete can be evaluated.
