Ø Product Features

l Testing machine host

u The testing machine is a four column frame structure with a main oil cylinderTwo way downSet, main structureIt consists of components such as base, oil cylinder, piston, hydraulic digital sensor, light bar, upper crossbeam, etc.

u The testing machine adopts high sealing singleto, toward, at, facing/Bidirectional oil cylinder, high efficiency and strong durability.

u The design of the testing machine takes into full consideration aesthetics, convenience, and safety. For example, the main structural components are made of high-strength iron plates, which provide strong rigidity and good stability for the entire machine;

u The force measuring element is a high-precision hydraulic digital sensor, which is subjected to unidirectional force. It is a key component for detecting the testing force of this machine. The electrical signals emitted when subjected to force are collected and processed by computer measurement and control software; This sensor has high accuracy, good repeatability, and good long-term stability.

u When the testing machine uses sensors to detect residual deformation indicators of manhole covers, the micrometer can be fixed in the appropriate center position with a magnetic gauge holder through the center opening position of the upper beam, which has the characteristics of convenience and flexibility, and accurate and effective measurement values. This sensor has the characteristics of high accuracy and resolution, strong seismic and anti-interference ability, and good repeatability.

l Test oil source cabinet

u Integrated oil source cabinet, composed of hydraulic pump station, oil source control, host control, measurement and control system, computer, etc., with built-in radial piston oil pump for stable output and low noise，The oil source cabinet has high integration, small footprint, and easy operation and observation.

u The entire oil source system adopts servo closed-loop control, equipped with digital servo valves, motors with stable torque and speed, high-precision valve plate groups and other components with fast response and high sensitivity; The system monitors parameters such as load and deformation in real-time, with features such as tracking, following, and adjustability, and can achieve fully automatic and precise control.

l Measurement and Control System

u The measurement and control system includes digital servo valves with high precisionHydraulic digital sensorThe controller and software have high control accuracy and good reliability.Measurement and Control SystemAdopting high-speed EthernetThe network communication interface communicates with computers and has multiple control modes such as load and stress, as well as screen displays of test force, peak value, deformation, and various test curves, and can achieve smooth switching of control forms.

u The experimental data is managed using a standard database and can be accessed freely. It allows for reanalysis, local amplification, and data editing of the experimental data and curves. It can automatically calculate various mechanical performance indicators of the material, print out complete experimental reports and curves (non configured printers), and provide network data interfaces.

u The measurement and control system has multiple limit protection functions, such as force overload protection, force channel overspeed protection, range limit protection, etc.

u The measurement and control system can be programmed by users according to experimental needs, such as cyclic loading, test force maintenance, etc.
