Computerized electrohydraulic servo hydraulic testing machine for
steel and concrete with high precision
Product introduction:
This machine is primarily used for testing the mechanical
properties of prestressed steel strands and can also be applied to
testing the mechanical properties of steel bars. Special jaws for
steel strands can guarantee the fracture position of the specimen,
thus measuring the true effective value of the steel strand. For
rebar and other materials, the test operation and data processing
comply with the requirements of GB/T 5224-2014 Steel Strand for
Prestressed Concrete and ISO 6934-4. Testing can also be conducted
in accordance with standards such as GB, ASTM, DIN, ISO, JIS, and
BS.
Price advantage:
We strengthen our independent R&D efforts, establish a
processing center, and independently manufacture core components.
This allows us to cut down on link costs while maintaining
consistent quality. Our high-quality products can save you far more
than those low-priced but poor-quality alternatives. Lowering the
machine's failure rate reduces customers' maintenance costs and
also enhances machine efficiency. Such a combination of competitive
pricing and high quality delivers real benefits to customers.
Frequently Asked Questions:
Q1. Are your company a trading one or a factory?
A: Factory-trade integration. We have 18 years of focus on the test
instruments field and 14 years of export experience.
Q2. How to choose the most suitable products?
A: Our professional team will offer the best suggestions as long as
you inform us of the type of test you need to conduct and the
required specifications.
Q3. What's the delivery term?
A: Most of the time, we have stock in the factory. If there is no
stock, the delivery time is normally 15-20 working days after
receiving the deposit.
If you are in urgent need, we can consider making special
arrangements for you.
Q4. Do you accept customization service?
A: Yes, of course. We can not only provide standard machines but
also customized ones according to your requests.
Feel free to tell us your requirements, and we will try our best to
meet them.
Q5. Can we visit your factory before ordering?
A: Yes, we warmly welcome and sincerely invite you or your team to
visit our factory. We will help arrange hotels and pick you up from
the airport.
Q6. How about your warranty?
A: Generally, our warranty period is one year. Within the warranty
period, we can provide technical support and replace spare parts.
If necessary, our engineers may visit your location for better
service.
Q7. How about the packaging for the machine? Is it safely protected
during transportation?
A: Our machines are packed in standard export wooden boxes, so they
won't be damaged. We have delivered many testing machines abroad by
sea or air without any damage.
Equipment expansion:
The design of the testing machine also takes into account the
expansion of other fixtures to enable more possible tests. For
instance: with bolt fixtures, it can be used for bolt stretching
and load holding; with bending fixtures, it can perform bending
tests on round rods or plates; equipped with shear clamps, it can
conduct shear strength tests on round rods; in the compression
space, flexure, shear, and splitting tests can be carried out, and
an elastic modulus meter can be added for testing concrete and
cement samples. Additionally, with fixtures for steel balls, anchor
chains, fasteners, etc., it can complete tests on these products.
Software System:
The test software runs on the Windows operating system and comes
with programmable features. It allows any combination of various
test modes, such as constant rate test force control, constant rate
displacement control, test force holding, and displacement holding.
This can meet the requirements of different test methods to the
fullest and achieve functions like data display, curve plotting,
data processing, storage, and printing as needed for the test. A
control signal is sent from the computer to the servo valve to
regulate its opening and direction, thereby controlling the flow
into the cylinder and realizing constant speed test force and
constant speed displacement control. It has complete file operation
functions, enabling test reports, test parameters, and system
parameters to be stored in file format. The system has different
management levels, and system parameters are accessible to expert
users, ensuring the system is flexible and reliable to use.
Standards:
ISO 6892, ISO 6934 BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4,
ASTM E8 and BSEN standards.
Preparations before installation:
The testing machine should be installed in a clean, dry,
vibration-free room with a room temperature ranging from 10℃ to
35℃. Sufficient space (≥0.7m) should be left around the testing
machine for testing and maintenance purposes.
The main body of the testing machine should be installed on a
concrete foundation. The size of the foundation should be
determined based on the shape and the foundation drawing, and space
should be reserved for the installation of anchor bolts and other
electrical wiring conduits, etc. The upper plane of the foundation
should be leveled using a frame-type level. A dedicated oil source
does not need to be installed on the foundation but requires the
four corners to be level to avoid vibration and noise.
