What are the important components of a hydraulic testing machine

Dates: 2020-03-23

Before using the hydraulic testing machine, you need to be able to clearly understand the characteristics of these equipments in order to provide better product use assistance for everyone. Many people choose to use these products now because the characteristics of the trustworthy hydraulic testing machine enable everyone to get good results when using them. Many people use hydraulic testing machines because they have very accurate experimental data. What are the important components of hydraulic testing machines?

What are the important components of a hydraulic testing machine

1.Sensor


The sensor is the guarantee of the accuracy and stability of the hydraulic testing machine. The important components of the electronic testing machine sensors on the market are S type and spoke type. The resistance of the internal resistance strain gauge of the sensor and the rubber of the fixed strain gauge will affect its product characteristics. The poor material of the sensor of the hydraulic testing machine will affect the accuracy of the sensor.


2.Ball screw


The screws currently used in hydraulic testing machines include ball screws and lead screws. Generally, trapezoidal screws have larger clearances, greater friction, and shorter service life. At present, some manufacturers on the market will use trapezoidal screws instead of ball screws in order to save more costs. They need to purchase correctly. The principle of selection is not necessarily above the price, but according to user needs.


3.Motor


High-quality hydraulic testing machine motor adopts AC servo speed regulation system, Panasonic AC servo motor, stable and reliable performance, with over-current, over-voltage, overload and other protection devices. Electronic test machines using general three-phase motors or variable-frequency motors are also currently on the market. This motor uses analog signal control to achieve accurate positioning. Generally, the speed range is narrow without high speed and the speed control is accurate.


4.Transmission system


There are mainly two types of transmission parts for hydraulic testing machines. One is a circular arc synchronous gear belt and a precision screw drive; the other is an ordinary belt drive. ,long lasting. The second transmission method cannot guarantee the synchronization of the transmission, so the accuracy and stability are not as good as the first transmission system.


All in all, the important components of a hydraulic testing machine are sensors, ball screws, motors, and transmission systems. Good after-sale hydraulic testing machine uses brand computer, control system software is operating system platform, has the advantages of fast running speed, soft interface, simple operation, etc. It can meet the test and measurement of different materials. It needs to be tested according to standards or industry standards to measure various materials. Physical properties.
