Tightening operation and torque selection and adjustment of electric torque wrench bolts

Tightening operation of electric torque wrench bolts
1. Install a counter force bracket and tighten the screws. Turn on the main unit so that the square pin hole corresponds to the reaction bracket hole, then install the wrench sleeve, insert the pin, and fix it with the rubber ring.
2. Adjust the torque knob of the controller to the required torque value, turn the positive/negative switch of the main unit to the forward rotation position, and put the wrench sleeve on the six sides of the threaded connection.
3, press the power switch, wrench start. When the force arm of the reaction force stand is placed on the stand (the fulcrum can be a nearby bolt or other fulcrum), the bolt is tightened. When the torque of the bolt reaches the predetermined torque, the wrench is automatically stopped and the tightening is completed. The power switch is released and the next bolt is tightened.
4. After the wrench is automatically stopped, rely on the elastic deformation force of the reaction force support to automatically disengage the force arm of the support from the fulcrum and remove the wrench. If the arm can not be separated from the fulcrum, you can toggle the positive and negative switch, click the power switch wrench to remove
 
Electric Torque Wrench Torque Selection and Adjustment
1. The user can arbitrarily select the corresponding size electric wrench within the range of 250-3500Nm.
2. There is "torque adjustment knob" on the control panel. Engraved with 0-10 scale value. The function of the fine adjustment knob is to adjust and compensate between coarse and fine adjustments to improve the torque control accuracy. (see next page)
3. Adjustment method: The product is shipped with a torque test data card for user calibration reference, the user can select a certain scale value according to the required torque, tighten the bolt, use a measuring wrench or other test. The force instrument measures the actual torque value of the bolt. If the torque difference is small, fine compensation can be used to compensate. If there is a large difference, the coarse adjustment can be adjusted up or down one gear, and several times to obtain the required torque value.

Brief Introduction & Working Principle

CW series gyratory screen is one of our main products. It`s superior quality, excellent performance and high efficiency won us a good reputation among our customers home and abroad.

The material moving track on screen begin with horizontal circular motion at the feed end,  gradually diminishing along the length of the machine to an elliptical path,and finally to an  approximate straight line motion at the discharge end. The material have enough time to  move on the screen, until the screening process is finished,that is why this machine have  huge handling capacity.

The unique gyratory motion imparts a combination of actions to the material as it passes  along the screen surface. It begins with a horizontal circular motion at the feed end, gradually diminishing along the length of the machine to an elliptical path, and finally to an approximate straight-line motion at the discharge end. There is no vertical component to this motion thus keeping   the material in constant contact with the screen surface. Whole sealing structure, no dust pollution. Without vertical vibration, the mesh could gain a longer service life.



Features

* No vertical vibration when working,longer life span of the screen mesh. (best choice for fragile materials, such as salt, sugar etc. )

* Capacity is about 4 times compared with S49-B series Vibrating Screen

* Low power consumption and high screening efficiency

* Price is much higher compared with S49-B series vibrating screen

* It can be designed in square or linear type

* Self cleaning device available
