Impeller normally applied in the centrifugal pumps.
Impeller is a rotating component equipped in the Pump Housing, help to transfer to energy from the motor that drives
the pump to the fluid being pumped by accelerating the fluid outwards from the
center of rotation.
QFAP supply various kinds of impellers to all over the world, main of our customers are from
Europe, North America, Japan and Southeast of Asia.
Materials:
grey Iron, ductile iron, steel castings, aluminum die castings, etc.

This tester is mainly used for various strength determinations of various textiles and their composite materials.
During the entire test, the gripper holding the specimen is fixed and the other is moved at a constant speed, so that the elongation of the specimen is proportional to the time. Principle: The sample of the specified size is stretched at a constant rate of elongation until it breaks off, and the breaking strength and elongation at break are recorded.
Second, technical indicators
Test force range:0～5000N
Test force accuracy: 1%
Stretching gauge range: 0 ~ 400mm
Sample clamp initial distance: 20mm
Power supply: 380V50HZ0.2KW
Third, the electrical control box button and display instructions
Rising - Press this button to move the upper chuck up and stop automatically when it reaches the upper limit position. Press this button to move the upper chuck downwards and stop automatically when it reaches the lower limit position. Press this button. Chuck stop movement force value - real-time display of the sensor output force value, can also display the maximum value of the sensor output during the test; can be pressed to perform real-time switch between the power value and the maximum power switch - press to "1" energizing the instrument, press "0" to power-off the instrument <br> <br> IV Procedure
1. Turn on the power switch and warm it up for 5 minutes.
2, by "rise", "decrease", "stop" button, move the chuck to the test required distance, clamping the sample.
3. Press on the force meter, then press and hold for 2 seconds to clear the value on the force meter. Then press "Up".
4. After the specimen is broken, press the “stop†button; record the force value and the length of the fracture, and complete the test once.
5, record the maximum force value, the direction of ≥ 780N (mass per unit area ≥ 200g /) / ≥ 490N (mass per unit area <200g /), zonal ≥ 390 as qualified.
V. Precautions
1. The sensor configured by this instrument is a precision device and should avoid the impact and distortion of external force.
2. The instrument is equipped with an upper chuck stroke limit switch. When the upper chuck reaches the upper and lower limit positions, the instrument protects itself and the upper chuck stops moving.
3, non-professionals do not open the box to move the parts of the instrument.
4. When the motor is running, it is forbidden to place the head, hand, etc. near the chuck and moving parts to avoid injury.
5, in case of emergency cut off the power quickly! Check the cause and re-power on.
6, the instrument power supply should have a reliable grounding.
