Material universal testing machine is one of the most widely used equipment, and can be divided into electronic universal testing machine and hydraulic universal testing machine. What is the difference between these two? How to determine which universal test machine to choose? Jin Mao Yongmao Xiaobian to answer your questions.
1. Electronic universal material testing machine mainly uses motor as power source, plus reducer, frequency converter, screw rod, gear chain, etc. as the executing parts to realize the movement of the beam. Because it does not use oil source, it is cleaner, easier to use and maintain, and its test speed range can be adjusted. The test speed can reach 0.001mm/min-1000mm/min, and the speed ratio can reach as much as 1 million times. The test stroke can be Need to be more flexible.
2. Electronic load testing machines use load sensors for force measurement. If you need to take more complex parameters, microcomputer control electronic universal testing machine is your better choice. From the perspective of cost performance, the choice of power within 30T, electronic universal testing machine has an advantage.
3. Hydraulic universal material testing machine uses high pressure hydraulic source as power source. Use manual, servo or proportional valves as control elements for control. Ordinary hydraulic universal testing machine can only be manually loaded to achieve manual, is an open-loop control system, subject to price factors, load cells generally use hydraulic pressure sensors. Electro-hydraulic servo universal material testing machine uses servo valve or proportional valve as control element to control. Jinan Yongmao testing machine has adopted high-precision load cell to measure force. Electro-hydraulic servo universal material testing machine is suitable for more requirements. High steel, building materials testing laboratory. More than 30T electro-hydraulic servo universal material testing machine is more expensive than electronic universal testing machine.

Tower Crane. Also known as tower crane, referred to as tower crane, in construction machinery, generally refers to the body of the tower-type structure of the full rotary jib crane, for large-scale civil engineering construction site common means of transport, building materials, construction machinery handling, high and low, vertical and horizontal direction can also be crossed, the task of moving objects can be quickly completed.
