Shanghai Shiqian Industrial Co., Ltd. is a professional manufacturer and distributor of universal tensile machines. This universal tensile machine produced by the company adopts the servo motor drive system to drive the crossbeam up and down to realize the test loading process. With precise loading speed and force measuring range, it has higher precision and sensitivity for the measurement and control of load, deformation and displacement. It can also carry out constant speed loading, constant velocity deformation, constant velocity displacement automatic control test, and has low Week load cycle, deformation cycle, displacement cycle and other functions. Applicable to metallurgical industry, petrochemical industry, aerospace, shipbuilding industry, machinery casting, automobile manufacturing, rubber and plastics, composite materials, wire and cable, wind power, photovoltaic energy, medical equipment, biomedical, door and window building materials, wood construction, textile fiber , paper packaging, electronic and electrical, wire and cable, medical equipment, nuclear power, universities, research institutes, technical supervision, commodity inspection and arbitration departments and other fields. Next, Xiao Bian came to tell everyone how to maintain the universal tension machine, and how to identify some of the advantages and disadvantages of universal tension machine.
Universal Rally Machine Maintenance and Maintenance:
1. During the test, attention should be paid to the position of the moving beam to ensure a good test space;
2. The screw should be lubricated every month, and check the condition of the oil in the reducer.
3. Please pay attention to keeping the testing equipment clean. After the test is completed, clean the site.
4. An abnormal phenomenon occurs during the operation of the equipment. Immediately press the emergency stop button.
How to distinguish the advantages and disadvantages of Universal Rally machine:
1. Software and hardware: The universal universal tension machine adopts brand computer, and the control system software is WindowsXP operating system platform. It has the characteristics of fast running speed, mild interface, simple operation, etc. It can meet the needs of different materials for testing and measurement, according to national standards. International standards or industry standards measure physical properties of various materials.
2. Ball Screws: The currently used nuts for universal tensioning machines are ball screws and trapezoidal screws. In general, trapezoidal screw gap is relatively large, the friction force is relatively large, and the service life is short. At present, there will be some manufacturers on the market. In order to save costs and obtain greater profits, trapezoidal screws will be used in place of ball screws.
3. Motor: High-quality universal tensile motor adopts AC servo speed control system, Panasonic AC servo motor, stable and reliable performance, transformer test has over-current, over-voltage, overload and other protection devices. At present, there is still an electronic universal testing machine using ordinary three-phase motor or variable frequency motor, which uses analog signal control, slow control response, positioning is not accurate, the general speed range is narrow and there is no high speed, there is no low speed or low speed No speed, and speed control is inaccurate.
4. Sensor: The sensor is an important component of the tensile testing machine's accuracy and force measurement stability. Currently, the types of tensile testing machine sensors on the market are S type and wheel type. Sensor internal strain gauges are not high accuracy, fixed strain gauges with plastic aging resistance is not good, the sensor's material will affect the sensor's accuracy.
5. Transmission system: There are two kinds of transmission parts of universal tensioning machine. One is circular arc synchronous gear belt, and the other is normal belt transmission. The first transmission method has stable transmission, low noise, high transmission efficiency, high precision, and long service life. The second transmission method cannot guarantee the synchronism of the transmission. Therefore, the accuracy and stability are not as good as those of the first transmission system.

Camping Folding Table
Characteristics of modern-day folding tables and chairs originated in medieval times, a period from the fall of
the last Roman Emperor, in 476 AD, to the fall of Constantinople, in 1453.
Furniture makers deliberately built tables and chairs that could easily be disassembled and transported. So
when harsh fighting erupted between nations, lords, and neighbors, families could grab their belongings
and flee at a moment's notice. Most of the tables of this era collapsed rather than unfolded.
Bed and Board
Interestingly, the expression "bed and board " was coined in the Medieval era with the latter "board"
referring to the main table used for dining. The "board" was just that - a portable trestle table that could
easily be packed away when not in use and transported with ease. Folding chairs were popular amongst
the medieval aristocracy since again they could be easily folded and carried when on the move. Styles
were simple and practical. They were usually made of oak or other woods.
Folding tables have evolved through the centuries with the emergence of new technologies and designs.
Today's tabletop options range from wood, particle board, and melamine, laminates, aluminum, plastic,
and so forth. Table legs can be built with steel, aluminum, other metals, and plastic. So while the main
use of folding tables has changed throughout history, the purpose remains the same - collapsible,
easily storable, portable, and lightweight.
