Technical description of universal testing machine

The universal testing machine is a precision testing instrument for measuring the mechanical properties, process performance, internal defects and dynamic unbalance of rotating parts in metal materials, non-metal materials, mechanical parts, engineering structures, etc. under various conditions and environments. In the process of researching and exploring new materials, new processes, new technologies and new structures, universal testing machines are an indispensable and important testing instrument.
There are many classification methods for universal material testing machines. Common ones are:
1. According to the type of output source, there are mainly motor, hydraulic, pneumatic, electromagnetic and so on;
2. According to the indication type of the measurement end, there are mainly digital display and pointer;
3. According to the relationship between the load and time of the sample, there are mainly: static machine and fatigue machine.
4. According to the control mode, there are mainly open loop control (manual control) and closed loop control (automatic control).
For closed-loop control control types are: speed control, load control, deformation control, position control.
5, according to the use of the main general purpose machine, special machine.
There are many types of special machines, such as: cement presses, red brick presses, wire bending fatigue machines, electric porcelain bending machines, lying pulls, etc., far balance machines, far three axes, vibration tables.
The tests that the universal testing machine can do are:
Stretching, compression, bending, tearing, peeling, cutting, etc.
Mechanical properties, also known as mechanical properties, material resistance and deformation performance
1. Mechanical properties include strength. Elasticity, plasticity, creep, fatigue and strength, etc.
2. Definition of strength: the ability of materials to resist various deformations and damages under external forces
3. Strength index has yield point. Tensile strength. Fatigue limit. Creep limit. Durable strength, etc.
4. Tensile test (strength indicators are: spring modulus. specified non-proportional elongation stress. tensile strength. zui vigorously, etc.
Jiangsu Tianhui Testing Machinery Co., Ltd. is a professional service manufacturer engaged in material testing and testing equipment. It integrates R&D, design, production, sales and service, and provides solutions for material testing and finished product testing.

Greenhouse Sun-Shading System

Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.

Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
