How to adjust the hydroulic universal testing machine level, Ji SPAN machine< test nan>manufacturers to explain for you:

The test machine generally has many vertical load-bearing columns, with a fixed horizontal base installed on the columns and a movable cross beam on the top. Modern new hydraulic universal testing machine, the columns are generally equipped with ball screws to fix the movable cross head. The size of the hydraulic universal testing machine is characterized by a load-bearing level of the frame and a dynamometer measuring load/tension force. The dynamometer is mounted on a movable cross head driven by an electric motor or hydraulic device. The series of dynamometers with fixtures measure the magnitude of force, and the results can be displayed through a digital display or PC. Many universal testing machines have interchangeable dynamometers and therefore can match the different materials tested. Static tests are carried out using a standard hydraulic universal testing machine, and the usual loading speed range is 0.001~20 in./min (1in.=2.54cm). Dynamic or cyclic tests such as crack growth and fatigue tests are usually performed using a hydraulic servo system universal test machine, which takes longer time and lower loads.

Testing machine generally have many vertical bearing column, column are arranged on ahorizontal base fixed, at the top and a movable cross beam. Modern hydroulic universal testing machine, the column are usually equipped with ball screws to fix the movablecrosshead. Hydraulic universal testing machine with the size of the framework of themaximum load level and load / force measuring dynamicometer to common characterization. The dynamicometer is installed on the cross head on electric motors or hydroulic device to drive the movable. Series of dynamicmometer measurements with clamping force size, the results can be displayed by digital display or a PC machine. A lot of universal testing machine with interchangeable dynamic, so it can be matched with different materials testing. The static test with standard hydroulic universal testing machine to carry out, usually the loading speed is in the range of 0.001~20 in./min (1in.=2.54cm). Dynamic test and cycle test such ascrack growth and fatigue test often used the hydroulic servo universal testing machine system for a long time, low load.

The hydraulic universal testing machine stretches, bends, compresses or pulls the splines of plastic material through adjustments at different speed levels. This is an ordinary equipment in plastic mixing laboratories. During the preparation of compounding, the test material can be used to determine whether the material is suitable for certain specific processing applications or terminal applications. It can also be used for product quality control to ensure consistency between batches of product quality.

Hydraulic universal testing machine by different speed level adjustment, the plastic materialpline tensile, bending, compression or traction, this is the most common plastic mixed with laboratories equipment. In the process of preparing mixed ingredients, using the test materialssto determine whether the material is applied in some special processing applications orterminal application. Can also be used to control the quality of the products, to ensure the consistency between each batch of product quality.

Currently, common items tested with hydraulic universal testing machines are tensile strength and tensile modulus, bending strength and modulus. Generally speaking, vertical devices are smaller and easier to operate, and can also make difficult samples such as films as heavier injection molded parts by the gravity of the sample itself. The force range of a single column universal test machine is relatively low and the price is also low. The structural capacity is generally 1000 lb. The structural capacity of a door-type universal test machine can reach 1000~135000 lb. The force gauge is also classified based on a certain force value suitable for the structure and sample of a universal test machine. For example, a 100 lb dynamometer is installed in a 1000 lb mold frame and can provide a 100 lb test load. The capacity of the dynamometer should not exceed the sample's predicted fracture load, otherwise it will affect the accuracy of the test results.

At present, the hydrous universal testing machine test the most common project is tensile strength and tensile modulus, bending strength and modulus. Generally speaking, smallervertical equipment is more easy to operate, and also with the help of sample self gravity, the difficult samples such as film can also like injection molding components heavier easy manipulation. Range of single column universal testing machine is low, the price is low, the structure capacity generally structural capacity is 1000~135000 lb. ergometer 1000 lb. door type universal testing machine to apply a maximum in the universal testing machine structure and sample force value as the basis for classifying. For example, a dynamicmometer installed100 LB at 1000 LB die box, can provide a test load of 100 lb. The dynamicmometer capacityshall not exceed the sample predicted fracture load too much, otherwise it will affect theaccuracy of test results.
