Important Factors And Correct Maintenance Methods Affecting The Dual Column Universal Testing Machine

The double column universal testing machine is mainly suitable for testing metal and non-metal materials, such as rubber, plastic, wire and cable, fiber optic cable, safety belt, belt composite material, plastic profile, waterproof coil, steel pipe, copper profile, spring steel, bearing steel, stainless steel (such as high hardness steel), castings, steel plates, steel strips, and non-ferrous metal wire for tension, compression, bending, cutting, peeling, tearing Two point extension (requiring an extensometer) and other tests. This machine adopts an electromechanical integrated design, mainly composed of force sensors, transmitters, microprocessors, load driving mechanisms, computers, and color inkjet printers. It has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in measuring and controlling loads and displacements. It can also perform automatic control experiments for constant loading and constant displacement. The floor standing model, styling, and painting fully consider the relevant principles of modern industrial design and ergonomics.

The ball screw, sensor, motor, software and hardware, and transmission system of the double column universal testing machine are important components of the testing machine, and these five factors play a decisive role in the double column universal testing machine

1. Ball screw: The double column universal testing machine currently uses ball screws and trapezoidal screws. Generally speaking, trapezoidal screws have a larger clearance, greater friction, and shorter service life. At present, some manufacturers in the market will use trapezoidal screws instead of ball screws to save costs and achieve greater profits.

2. Sensors: Sensors are important components for improving the accuracy and maintaining force stability of testing machines. Currently, the types of sensors available on the market for dual column universal testing machines include S-type and spoke type. The low precision of the resistance strain gauge inside the sensor, the glue used to fix the strain gauge, the poor anti-aging ability, and the poor sensor material will affect the accuracy of the sensor.

3. Testing Machine Motor: The high-quality electronic universal testing machine motor adopts an AC servo speed control system. The AC servo motor has stable and reliable performance, and is equipped with protective devices such as overcurrent, overvoltage, and overload.

At present, there are still some electronic universal testing machines on the market that use ordinary three-phase motors or variable frequency motors. These motors use analog signal control, which has slow control response and inaccurate positioning. Generally, the speed range is narrow, and if there is high speed, there is no low speed or if there is low speed, there is no high speed, and the speed control is not accurate.

4. Software and Hardware: The high-quality dual column universal testing machine adopts a branded computer, with the control system software as the operating system platform. It has the characteristics of fast running speed, gentle interface, and simple operation, which can meet the testing and measurement needs of different materials. It can measure the physical performance tests of various materials according to national standards, international standards, or industry standards.

Transmission system: There are two main types of transmission parts for electronic universal testing machines: one is arc synchronous gear belt, precision screw pair transmission, and the other is ordinary belt transmission. The first transmission method has stable transmission, low noise, high transmission efficiency, high accuracy, and long service life. The second transmission method cannot guarantee the synchronization of the transmission, so the accuracy and smoothness are not as good as the first transmission system.

The Correct Maintenance Method For The Dual Column Universal Testing Machine

1. Host Inspection

Is there a requirement that is pertinent to inspect the main machine of the testing machine, with the primary focus being on examining the pipes that connect the hydraulic pump station to establish whether or not there is any oil leakage in the pipelines and whether or not the jaws are worn? It is also important to examine the anchor nuts to see whether or not they are loose.

2. Inspection Of Oil Source Control Cabinet

In addition, the oil supply control cabinet, which is considered to be one of the most essential components of the machine, serves as the major source of the power drive component. Therefore, the examination of the oil source control component should not be carried out in a careless manner but rather should be taken extremely seriously. This is because of the importance of controlling the oil supply. Examining not just the performance of the oil pump motor but also the condition of each solenoid valve and determining whether or not it is able to work correctly is something that should be done.

3. Hydraulic Oil Inspection

The same idea applies to electronic testing instruments in the same way that the oil in frequently used automobiles needs to be refilled when a specific mileage point has been reached. There are occasions when hydraulic oil is referred to as the "blood" of the machine. For about one year after it has been used, it is important to replace the same grade of anti-wear hydraulic oil. This is a requirement.
