GEW series computing display strand testing machine .Applications: This series of testing machine is mainly used to test the tensile
strength、elastic modulus、tensile rate、p0.2 of the strand. Assembled with clamp, this machine also could carry out
compression, bend test on metal, metalloid and part. The testing
machine is not only quite up to the requirement of the steel
stranded wire stretching testing of GB/T 5224-2003 Prestressing
concrete, suitable for strand stretching testing, but also quite up
to the standard of GB/T 17671-1999, suitable for cement mortar
resist compression、resist break testing, and satisfies with the
standard of GB/T232-1999, suitable for bend test of metallic
material(need to assemble with interrelated clamp). .configuration 1. computer system: this series of testing machine adopts DELL computer with three
years’ free service, and can be updated as the users’ requirement,
equipped with common extensometer and big-size strain gauge with
the scale distance of 500. 2. hydraulic system: hydraulic component in this machine adopts the new products of
china, the top company in China in order to ensure stability of the
system. External tunable and pretightening force hydraulic chucking
fixture has the advantages of little influence to subjectival
rigidity, convenient to maintenance. 3. loading system: this system is improved based on the basic of our company’s
product of WE series, it adopts non-obturating ring the way of slit
seal between cylinder and piston. The system’s friction force is
little in order to ensure the dynamometric system’s high degree of
accuracy and long life. It also adopts imported high pressure gear
pump with the advantages of cramped construction and low noise. 4. clamping system: it has partly modified design in the stressed span of pedestal on
the top 、bottom mouth of tongs, enforces the intensity of mouth of
tongs, meanwhile, reduces retaining angle of wedge grip and
increases retaining length of sample. Tried to reduce the
impairment outside of the testing piece, then, augment the chucking
power on the testing piece. This system also configures separate
oil sources retaining system, which top of chucking power is 200KN,
to avoid the mutual interferer with the main oil source. 5. electric system: Electricial component getting in touch with the human body, such
as button, hydraulic- electric component are all adopted the 24V
electric power. It is safe to the operator, also Prevents winding
from burning easily. 6. software system: self-made PA－201 card (PCI) has been integrated multi D/A
diversion and amplifying function. This product all adopts digital
form design, doesn’t include any tunable analog components, which
can ensure the stability of the product. control software is
written by the language of DELPHI, which is ceaselessly improved
and perfected in recent ten years. in the operational
efficiency、expandability、stability and intelligent, this soft has
large progress. .Feature： 1. adopt inserting-card design, compact structure, excellent
compatibility and stability; 2. Having been done many modifications and perfection on the
proposal of testing data processing, which includes nearly infinite
data storage ability、optional testing report content for the
users、intelligent evaluation for the result of test, ect. 3. reserve the memory interfaces of local database and network
database, supply users with interface protocols, so it is
convenient to link the internet. 4. in the software, it has been prefabricated the standard of steel
stranded wire stretching testing and metal compression、bend
testing. If users want to test according to other standards, we
also could freely prefabricate the specific testing standards for
users. 5. it could measure material’s important testing data, such as
elastic modulus---E、p0.2、b、tensile rate and so on. 6. separate hydraulic pressure chucking oil sources, it could
supply the top chucking power of 200KN, also could reduce the
mutual interferer with the main oil source. 7. adopt lengthened wedge grip, it is favorable for setting up nip
for the testing piece. 8. configure appropriative big-size strain gauge, after the test,
it needn’t to lift down the gauge. It's a great convenience to use
for users. .main specifications:
