YZH-300.10 Constant Load Cement Flexural Compression Testing Machine
YZH-300.10 constant load cement flexural and compressive testing machine is a pressure testing machine that integrates cement flexural and compressive resistance jointly developed by Zhejiang Luda Machinery Instrument Co., Ltd. and Zhejiang University of Technology
This product adopts anti-bending and anti-compression double oil cylinders to realize the test of cement compressive strength and cement flexural strength respectively.
Features:
High-precision digital micro-valve is used to realize the loading rate;
With the force closed-loop control function, it can realize the loading of the load stress rate;
The hydraulic pump adopts an axial five-piston ultra-high pressure pump, which works smoothly and has low noise;
The control valve adopts high-precision digital micro-flow valve with high control precision;
The sensor adopts a pressure sensor with good reliability;
The principle of automatic loading is adopted to strengthen the control of the loading rate.
