Computer-controlled Hydraulic-servo Universal Testing Machine
1. Product Overview
Computer-controlled hydraulic-servo universal test is to control the flow of oil into the cylinder by computer and produce mechanics testing conditions such as power with constant speed or displacement with constant velocity. The flow of oil is achieved by sending the controlling signal to valve-servo to control the size and direction of valve. By adding these conditions, various tests on mechanical properties can be conducted, such as stretching, compressing and bending of metal material, nonmetallic, product parts or structural parts.
Equipped with optional environmental-equipment, this serial of products can also help conduct tests based on specific environment, such as stretching and compressing of materials under high-temperature or low-temperature conditions.
The product is applicable not only for colleges and research institutes of mechanics engineering, but can also be utilized for factories, mines and enterprises of steel, metallurgical, hydraulic, hydroelectricity, highway and bridge-construction.
