Description

The main purpose

LEW series microcomputer screen display steel cable tension test machine is used for tensile strength test and analysis of prestressed steel wire.Test operation and data processing load GB/t5224-2003 “prestressed concrete steel wire” requirements.

The machine is composed of oil cylinder and lute oil source control cabinet, and the oil pump adopts the low noise high performance gear pump of Italian mazuchi.The stretch space is above the host, and the compression and bending test is located between the middle beam and the table.The adjustment of the test space is realized by moving the beam in the middle beam and the beam is driven by the chain.Manually adjust the oil intake to achieve the tensile, compression and bending of the material.After the experiment, the experimental results of automatic material FM, RPO. 2, RM and Ft were adopted.
