Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

Building brick pressure testing machine is used to measure the compressive strength of brick, stone, concrete and other building materials.

1. Body parts

Building brick four columns will block the body by the pressure testing machine and liang together, in the testing machine on the beam of regulating screw, and a hand wheel nut screw machine no-load height adjustable, screw on the bottom with a tee and clamp.The lower pressure plate is placed on the piston of the oil cylinder. When the test piece is in contact with the upper pressure plate, the upper pressure plate ball seat can adjust the positive balance to keep the test piece and the upper and lower pressure plate level.Down with specimen orientation with the scribed line in the class, do test specimen line is to be made on the press table below with dust cover shell, prevent or reduce dust into the cylinder when the piston lift, damage to the cylinder block and oil seal.Between piston and cylinder with sealing device, can prevent oil leaks, but when using the pistons still have traces of oil leaks, at the top of the cylinder block has a ring groove, and a drainage channel discharge, flow back to the big tank.

2. Hydraulic control part.

This building bricks of pressure testing machine main control box of oil tank, oil pump, oil filter, motor, speed and other components of the valve, oil return valve, oil pump for straight type axial pump with five poles, made the tester at the time of loading, shall be manually loading speed control valve into the piston is rising faster restoration control () the speed and the relief valve is one piece design, unloading, rotating oil return valve, oil cylinder will gradually decline.The testing machine has been transferred to the appropriate position when the test machine is out of the factory. The user cannot adjust the safety valve when normal use.
