Selection and Maintenance of Test Chambers
The selection and maintenance of constant temperature and humidity test chambers have been widely used in fields such as electronics, national defense technology, chemical engineering, mechanical manufacturing, and aerospace. 1. Three major purchasing suggestions for constant temperature and humidity test chambers are essential to ensure that users make correct and scientific choices when purchasing these chambers. The three main reasons to choose a constant temperature and humidity test chamber are: 1. Core technology of the test chamber; 2. After-sales service of the test chamber; 3. Transaction price of the test chamber. Only top-notch core technology...

How to use a universal testing machine
Universal Testing Machine Operating Instructions Author: Tai'an Tiancheng Testing Co., Ltd. 1) Check whether all valves in the oil circuit are in the closed position and whether the type and specifications of the clamps match the test piece, and check if the fuse has blown. 2) Select the appropriate range based on the maximum load required for the experiment, and configure the corresponding pendulum and adjust the buffer. 3) Install the drive device, pen, and paper of the automatic plotter. 4) First close the oil supply valve and return oil valve, then start the hydraulic pump motor. After the hydraulic pump is working normally, open the oil supply valve to raise the movable platform by about 1 cm to eliminate its self-weight; then close the oil supply valve.

How to choose a tensile testing machine
How to choose a tensile testing machine? Currently, there are many manufacturers producing electronic tensile testing machines in the domestic market; coupled with the entry of foreign brands and various types of distributors and offices, this market is quite chaotic. Due to the varying levels of quality and manufacturing processes among different manufacturers, there are discrepancies in prices, which can even be quite large. So how do we choose an electronic tensile testing machine that suits our needs? Below, we will briefly introduce the purchasing methods: 1. First, clarify the difference between electronic tensile testing machines and hydraulic tensile testing machines. 2. Working principle of electronic tensile testing machines: The motor drives the screw rod to rotate through a reducer.

How to solve the fault problems of universal material testing machines.
How to solve the fault problems of universal material testing machines? Universal material testing machines, also known as universal tensile machines or electronic tensile machines, feature an independent servo loading system and high-precision wide-band electro-hydraulic servo valves, ensuring high efficiency, low noise, and quick response. They use an independent hydraulic clamping system to ensure low noise and smooth operation, while securely holding the sample during the testing process without slipping. The universal material testing machine employs a microcomputer-controlled fully digital wide-band electro-hydraulic servo valve to drive a precision hydraulic cylinder. The microcomputer control system automatically controls various modes of test force, displacement, and deformation, completing tensile, compression, and bending tests on samples, in accordance with national standards.

Do you know what requirements the testing machine has for the performance of sensors?
Do you know what requirements the testing machine has for sensor performance? The testing machine sensor is mainly used for testing, and its primary testing objects are metal and non-metal materials. A high-quality testing machine sensor can effectively help us test the tensile and bending properties of materials, among others. So, do you know what requirements the testing machine has for sensor performance? Accuracy is an important performance indicator for testing machine sensors, as it directly affects the precision of the test results. Generally, the higher the accuracy of the testing machine sensor, the more expensive it is. Therefore, customers should choose testing machine sensors based on actual conditions.

What impact does the stretching speed of a rubber tensile testing machine have on the test results?
What impact does the stretching speed of a rubber tensile testing machine have on test results? The rubber tensile testing machine is a precision testing instrument used to determine the mechanical properties, processing properties, internal defects, tensile tests, compression, bending, and other tests of non-metallic materials such as rubber, plastics, textiles, and waterproof materials under various conditions and environments. So, what is the effect of the stretching speed of the rubber tensile testing machine on the test results? The tensile testing machine deals with viscoelastic materials, and the stress relaxation process is closely related to the deformation speed. When the stretching speed decreases, the tensile strength decreases, and the elongation at break increases; when the stretching speed increases, the plastic exhibits brittleness, the tensile strength increases, and the elongation at break decreases.
