YAW-5000 Fully Automatic Pressure Testing Machine

The YAW-5000 fully automatic pressure testing machine is a high-tech, versatile automatic pressure testing machine integrating modern mechanics, electronics, and hydraulics.Mainly detects compressive strength and physical stability under constant load of various bricks, blocks, cement products, hollow bricks, S-bricks, paving bricks, cement bricks, dock bricks, refractory materials, engineering materials and stone. Especially suitable for testing concrete products with strength grades C60 and C80.

Applicable industries:Widely used in laboratories across industries such as highways, railways, bridges, construction, building materials, and higher education institutions.

Functional Features

The measurement and control system adopts a high-precision digital servo valve with force closed-loop control capability, enabling constant load rate or constant stress rate loading. It offers high control accuracy, reliable performance, and uses a microcomputer for electronic measurement and automatic completion of compression strength tests, including automatic calculation and report printing. It is widely used in the construction industry and testing organizations.

Hydraulic system

Hydraulic oil from the tank is pressurized by a high-pressure pump driven by an electric motor and then flows through a check valve, high-pressure filter, differential pressure valve group, and servo valve before entering the cylinder. The computer sends control signals to the servo valve to adjust its opening and direction, thereby controlling the oil flow into the cylinder and achieving constant test force control.

Force measurement system

Adopts a high-precision amplifier and A/D converter, with no range switching throughout the process, and displays load, peak value, loading speed, and strength in real time;

Constant speed loading is achieved using a PID closed-loop control strategy, with the loading curve displayed in real time.

Automatic interval timing and continuous testing;

Querying and printing test results is flexible and convenient;

Safety protection device

When the test force exceeds the maximum test force3%In case of overload, the oil pump motor will shut down.
