yarn tension meter
1.portable,compact,mechanical tension measuring device.
2.dependence and accuracy.


1.Brief introduction of instrument:

Measuring apparatus this adopt accurate transmission device that develop newly,can

make the instrument in measurement steady accurate reading the necessary data fast.

this instrumental error values in positive and negative 1 Newton scope.

In the screen printing of network monitoring silk screen version of the manufacture and

use of the process Screen tension values may also be used for other needs Plane tension

measurement products.



2.Instruction:


1.Before using please put the tension meter on the glass and turn round the dial to make the pointer return to zero.

2.Flick the silk screen during measuring, the indication when the pointer stopped is the tension of the silk screen.

3.Tension meter is precision meter, fall and touch is forbidden, be careful during using.

4.Tension meter has been tested precisely when leave the factory, dismounting alone is

not allowed.

5. Can’t touch the bottom side contactor by hand, put the machine vertically without using.

6. The Newton indication is the indication of the tension’s contactor, the error is +0.5N.

7. The indication of the second circle is the measured value during measuring.



3.Warranty:

NR110 digital colorimeter electronic test instruments is under warranty for 12 months from the purchase

date. Customers must provide warranty card and valid proof of purchase.



















Q: How to deal with axial fan noise?
For the noise generated by the impeller, usually through the blade perforation approach to reduce noise, with the perforation method, you can make part of the air flow through the blade high pressure surface to the leaves low pressure surface, can promote the leaf separation point to move below the flow
Q: What is the reason for the vibration of the fan?
Fan of the impeller of the dynamic and static balance failed, with the fan after a certain period of time after the impeller uneven wear line caused by poor balance,
Q: How can a more intuitive distinction between centrifugal fans and axial fans?
The 3, oblique flow fan, also known as mixed flow fan is between the axial fan and centrifugal fan between the fan, oblique fan of the impeller so that the air is doing both centrifugal and axial movement, the movement of the shell of the mixture of axial flow and Centrifugal two forms of movement. Mainly used for mine ventilation and tunnel ventilation.
Q: What is the difference between a jet fan and an axial fan?
The guide vanes change the deflected airflow into axial flow and introduce the gas into the diffuser tube, further converting the kinetic energy of the gas into pressure energy, and finally introducing the working line. Axial fan blades are generally adjustable angle, most of the axial fan are equipped with a set of blade hydraulic regulator.
Q: How to determine the direction of centrifugal fan?
When the impeller is clockwise rotation and the fan outlet in the lower left to the horizontal direction when the gas is called the right 0 degrees
Q: Axial fans, centrifugal fans are called blowers?
The load behind the wind outlet to become a blower, the load in front of the wind inlet is the fan.
Q: What are the characteristics of high-pressure axial fans?
2. High reliability When the use of changes, the machine can still operate safely. In addition to the impeller, the high pressure blower has no other action, so the reliability is almost free of maintenance. It has the following advantages: high compression ratio; low bearing running temperature; long life of lubricating grease; maintenance-free.
Q: How to install explosion-proof axial fan?
The weight of the connecting duct should not be supported by the fan of the fan, and the support frame should be installed.
Q: What is the critical speed of the fan?
This speed is equal to the natural frequency of the rotor, when the speed continues to increase, close to 2 times the natural frequency amplitude will increase,
Q: What is the effect of the centrifugal fan on the wind pressure?
When the fan inlet and outlet is not connected to the pipeline, the largest air volume, minimum wind pressure, the largest power.
