The hydrostatic testing machine is a kind of equipment commonly used for testing the mechanical properties of materials, and its operation process and precautions have an important impact on the accuracy and reliability of the test results. This article will introduce the operation process and precautions of the hydrostatic testing machine in detail to help readers better grasp and use the equipment.
First, the operation process.
1.Preparation stage.
Before you start testing, here are some things you need to prepare:
1) Check whether the testing machine is in a normal state, including whether the power supply, hydraulic system, sensor and other components are working normally;
2) According to the test requirements, select the appropriate specimen and mold, and place them on the workbench of the testing machine;
3) Adjust the parameters of the testing machine, such as pressure, displacement, etc., to ensure that the test conditions meet the requirements.
2.Testing phase.
After the preparation is complete, you can start testing:
1) Turn on the power of the testing machine, start the hydraulic system, and apply static pressure to the sample;
2) Under the action of pressure, observe the deformation of the sample and record the test data;
3) During the test, it is necessary to pay attention to observe the working status of the hydraulic system and sensors to ensure the accuracy of the test results.
3.End phase.
After completing the test, the following needs to be done:
1) Turn off the hydraulic system and power supply of the testing machine;
2) Take out the specimen, measure it and record the data;
3) Clean and maintain the testing machine to ensure the integrity and service life of the equipment.
2. Precautions.
1.In the process of operation, it is necessary to pay attention to safety issues to avoid accidental injuries caused by improper operation;
2.Before testing, it is necessary to carefully check whether the specimen and the mold are matched to avoid test failure due to improper mold selection
3.During the test, it is necessary to pay attention to the status of the hydraulic system and sensors to avoid inaccurate test results caused by equipment failure
4.At the end of the test, the specimen needs to be carefully measured and recorded, and the data should be reasonably analyzed to arrive at accurate test results.
3. Common problems and solutions.
1.The testing machine cannot be started: first of all, it is necessary to check whether the power supply and hydraulic system are working properly, and if there is a problem, it needs to be repaired in timeSecondly, it is necessary to check whether the sensor is faulty, and if there is a problem, it needs to be replaced in timeFinally, it is necessary to check whether there are other faults in the testing machine, and if there is any problem, you need to contact professionals in time to deal with it.
2.Inaccurate test data: First of all, it is necessary to check whether the sensor is faulty or has a large error, and if there is a problem, it needs to be replaced or calibrated in timeSecondly, it is necessary to check whether the operation process of the testing machine is correct, and if there is any problem, it needs to be adjusted or corrected in timeFinally, it is necessary to check whether the specimen and the mold match, and if there is a problem, it needs to be replaced or adjusted in time.
3.Abnormal working of the testing machine: First of all, it is necessary to check whether the working status of the hydraulic system and sensor is normal, and if there is a problem, it needs to be repaired or replaced in timeSecondly, it is necessary to check whether the hydraulic oil of the testing machine needs to be replaced or replenished to maintain the normal operation of the hydraulic systemFinally, it is necessary to check whether other parts of the testing machine are faulty, and if there is any problem, you need to contact a professional in time to deal with it.
In short, the operation of the hydrostatic pressure testing machine needs to be carried out in strict accordance with the operation process, paying attention to safety issues and equipment maintenance issues. In the process of use, it is necessary to pay attention to the common problems and solutions of the equipment to ensure the accuracy and reliability of the test results.
