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

It is mainly used to test the wedge load tension test, tension test, guarantee load test and elongation rate of bolt, screw and stud.The pillar structure, the use of hydraulic load, the computer shows the test result, convenient operation, accurate and reliable test readings of general steel and other metal materials can do tensile, compression, bending and shear test, can also do general materials, such as plastic, cement and concrete compression and bending test.

GB/T3098.1-2002 fasteners mechanical properties bolts, screws and studs.

GB/T3159-2008 "hydraulic universal testing machine"

GB/T228-2002 "methods for tensile testing of metallic materials at room temperature".

GB/T 7314-2005, "compression test method for metallic materials at room temperature".

GB/T 232-2010 "test method for bending metal materials"

The hydraulic oil in the tank goes through the motor to drive the high pressure gear pump into the oil road. It flows through the one-way valve, the high pressure 10 mu oil filter, the pressure difference valve group and the oil delivery valve to enter the oil cylinder. By manually controlling the opening size of the feeding valve, the flow rate into the cylinder can be controlled, and the loading requirements can be satisfied. After the test is completed, unload the return valve and return the oil cylinder.
