200-ton concrete constant loading test moment press

       I. 200-ton Concrete Constant Loading Test Moment PressMain Purpose

    This testing machine is used to determine the compressive strength of building materials such as bricks, stones, and concrete.

     This testing machine complies with the standard "Standard for Test Methods of Mechanical Properties of Ordinary Concrete." It features computer-controlled loading speed, a loading speed indicator, peak hold, and overload protection functions. It is an essential testing and inspection equipment for construction, building materials, highway bridges, and other engineering units.

    III. 200-ton Concrete Constant Loading Test Moment PressStructure Introduction

The testing machine mainly consists of three parts: the body, solenoid valve, and computer control panel.

1. Body Part

The body of the testing machine is connected by four columns linking the cylinder and the upper beam.

On the upper beam of the testing machine, an adjustment screw, a large handwheel, and a nut screw are installed to adjust the no-load height of the testing machine. The lower end of the screw is equipped with a ball seat and an upper pressure plate. The lower pressure plate is placed on the piston of the oil cylinder. When the specimen contacts the upper pressure plate, the ball seat of the upper pressure plate can self-adjust for balance, ensuring the specimen remains level with the upper and lower pressure plates. The lower pressure plate is engraved with positioning lines for the specimen. During testing, the specimen must be aligned with these lines. A dust cover is installed below the lower pressure plate to prevent or reduce dust from entering the oil cylinder during piston movement, which could damage the cylinder or oil seal. A sealing device is installed between the piston and the oil cylinder to prevent oil leakage. However, if a slight oil leakage occurs during use, an annular oil groove at the top of the cylinder and an oil discharge channel will drain the oil back into the main tank.

2. Hydraulic Part

     The hydraulic system of this testing machine mainly consists of an oil tank, oil pump, oil filter, motor, solenoid valve, etc. The oil pump is a direct-rotation axial five-pillar pump. The safety valve has been pre-set to an appropriate position before leaving the factory. Under normal use, users should not adjust the safety valve.
