Specifications


1,Dry Sieve Test Apparatus
2,To determine the apparent/equivalent opening size of a geotextil


Application  


Geotextile Opening Size Tester is used todetermine the apparent/equivalent opening size of a geotextile by sieving sizedglass beads through the geotextile, using the dry-sieve principle. A geotextilespecimen is placed in a sieve frame and sized glass beads are placed on thegeotextile surface. The geotextile and frame are shaken laterally so that thejarring motor will induce the beads to pass through the test specimen. Theprocedure is repeated on the same specimen with various sized glass beads untilits apparent opening size has been determined. The apparent opening size (O90)of the geotextile corresponds to a specified size of graded glass beads passed(d90).

Q:Fire high temperature exhaust fan is a centrifugal fan?
The blades of an axial fan are not uncommon, and their shapes and working methods are largely similar to fan wings. Axial fans in the course of operation, through their own fixed position to move the air. This is mainly because of the fan
Q:How can a more intuitive distinction between centrifugal fans and axial fans?
Because the gas flows parallel to the fan shaft. Axial fans are often used in situations where the flow rate is high and the pressure is low. The axial fan is fixed and moves the air.
Q:Is the centrifugal fan plugging the air inlet motor?
That is, the centrifugal fan control mode, from the ordinary control mode to frequency control.
Q:What are the regulations for the air volume of the exhaust fan?
Bear two or more smoke partition smoke, should be the largest smoke partition area per square meter of not less than 120m3 / h basis.
Q:What is the difference between the fan and the compressor?
Blowers are usually air-cooled, oil-free. Although the blower can be designed for secondary and tertiary compression, but due to low efficiency. Usually single-stage compression, applied to low-voltage applications. Blowers are often used as vacuum pumps and pneumatic conveying.
Q:What is the difference between centrifugal fans and centrifugal fans?
DC ion fan is mainly by the two groups of electrodes simultaneously emit positive and negative ions, emitting positive ions when the launch of negative ions, to eliminate the effect of static electricity.
Q:What are the characteristics of high-pressure axial fans?
4. Oil-free pollution-free impeller rotation, not with any part of the parts contact, free lubrication, it can guarantee 100% pollution-free
Q:What kind of duct valves are required in the exhaust duct and near the fan?
The air flow control valve blades are open and open, and are used as control valves in ventilation, air conditioning and air purification systems.
Q:What is the reason for the vibration of the fan?
Fan and the motor, such as when the wheel connection, the wheel clearance is too small,
Q:What is the difference between general-purpose inverter and fan-type inverter
The constant power nature of the load should be in terms of a certain range of velocity variations. When the speed is very low, by the mechanical strength limit, TL can not be infinitely increased, at low speed into a constant torque properties
