new developed Hydraulic Universal Testing equipment(Four Column) HZ-005 - HZ-005

Four Column Type Hydraulic Universal Testing Machine

Introduction:

HZ-004 Four Column Type Hydraulic Universal Testing Machine used to a variety of metal materials, tensile, compression,

bending, shearing accompanied by increased shear test can be done, can be used as plastic, concrete, cement

and other non-metallic materials, compression tests, with simple accessories to complete the chain tape , wire,

welding rod, tile's wide range of performance tests and components.This machine adopt under the fuel

tank-mounted machine, low profile, light weight, especially for the engineering construction sector.

Host:

The Four Column Type Hydraulic Universal Testing equipment adopt oil cylinder under mounted type host,

stretching space is at the top of host, compression test space is between the at the work table and the crossbar .

Transmission system:

Down beam go up and down by the use of motor reducer, chain drive mechanism, vice

screw drive, to achieve tensile, compression of space to adjust.

Hydraulic System:

The oil tank is sucked through the filter screen and be inhaled pump oil ,through the petroleum

pipeline of oil pump transport to oil valve,When the hand wheel to send off the oil, due to the role of oil will push

the piston, the oil from the return pipe to tank, when the hand wheel to open get the oil, then the working fluid into

the fuel tank through the tubing, pressure tubing through and through oil return valve to tank.

Control system:

Electronic force measurement, liquid crystal display test force - time curve, test power, peak

test power, has obvious characteristics of the material yield strength yield the experimental data easy and intuitive;

Through digital button input sample numbers, cross-sectional area, can be directly measured the material tensile

strength, yield strength and other mechanical properties; can query the experimental results, print (with micro-printer)

Safety protection device:

a) When the test force more than 3% of the maximum test force, the overload protection, oil pump motor shut down.

b) When the piston rises to the upper limit position, stroke protection, pump motor shut down.

Fixture:Whole set fextures include:stretch fixture,compression fixture,bending fixture.
