Product Description:


YG011 fiber bundle strength tester is an instrument to check the holdingstrength and elongation at breakage of fiber tufts



STELOMETER is an instrument to check the holding strength and elongation at breakageof fiber tufts.

Holding strength reading on a graduated scale from 0 to 7 kPa (step0.1kPa), elongation reading on a graduated scale from 0% to 50%.



ISO 3060

Note: this tester can conform to but not limit to the standards above, formore standards conformance, please contact us.


l Calibrate each stelometer by force measuring andelongation devices that are special designed by our company only, ensurepointer indications (force value and elongation) are match to real value andkeep test result stable and high accuracy;

l Special designed table clamps and pressley clamp (we aresupplier for USTER) can hold fiber tufts effectively, and avoid slipping oraffect test as hold tight;

l Read test values of breaking strength and elongationdirectly from two scales after finishing test;                      

l After fiber tufts breaks, there is no malfunctionmistakes;

l Test result with high accuracy and with good correlationwith yarn strength.

Q:What is the role of the blower in the sewage treatment plant?
There are two purposes, one is to increase the oxygen biochemical bacteria to protect their living environment, to achieve the needs of sewage treatment
Q:What is the role of the fan?
Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust and cooling
Q:What is the difference between a jet fan and an axial fan?
The Based on the principle of impact transmission, the high-speed airflow transfers energy to another part of the air in the tunnel, causing it to flow backwards, pushing the air in the tunnel toward the outlet and sucking fresh air from the inlet. When the airflow velocity decays to a certain value, the next group of fans in the same way continue to drive air flow, to achieve the purpose of excluding air pollution in the tunnel.
Q:How to reduce fan noise?
3) centrifugal outlet due to the presence of the volute or the presence of the fan-shaped fan rear guide leaves produced by the presence of interference noise, discrete noise with discrete spectral characteristics, the fundamental frequency (i = 1 corresponding to the frequency) the strongest noise , Higher harmonics are decreasing.
Q:What is the operation of centrifugal fans and axial fans?
Centrifugal fan is based on the principle of kinetic energy conversion to potential energy, the use of high-speed rotation of the impeller to accelerate the gas, and then slow down, change the flow, the kinetic energy into potential energy (pressure)
Q:What is the working principle of centrifugal fans?
It is generally not necessary to consider changes in the specific volume of the gas, i.e., treat the gas as an incompressible fluid.
Q:Why does the fan start the current?
The fan is a mechanical fluid that relies on the input of mechanical energy, which increases the gas pressure and sends the gas to the gas. It is a driven fluid machine.
Q:What is the meaning of the residual pressure in the fan equipment parameters?
The concept of external pressure is generally from the manufacturer sample sample provided by the machine outside the pressure is generally considered the unit itself after the pressure loss can provide the full pressure, the sample in addition to providing static pressure outside the machine, will provide outside the machine Residual pressure value, but rather the machine is not necessarily have static pressure
Q:What is the reason for the vibration of the fan?
Fan inlet and outlet pipe design is unreasonable, causing resonance,
Q:Why should the safety valve be installed at the Roots blower exit?
Centrifugal fan is the rotation of the impeller, the energy transfer to the air, so that the air carrying energy along a certain direction of movement, and ultimately we feel is the movement of the "wind"
