Component performance of papermaking pressure screen equipment

　　1. Screen drum: The fine screen of the pressure screen of papermaking equipment uses water jet cutting technology to form excellent round holes and burr-free slots, which will not cause stress and slot end cracks like mechanical washing and grinding slots. It can also provide a hard degree of winding technology to improve wear resistance.

　　2. Rotor rotor: 3-4 rotors are installed on the refined pulp rotor, and the balance is strictly corrected after assembly, so that the rotor does not vibrate when rotating at high speed. The rotor is installed on the main shaft, and the rotor of Chengdu Rendering Company is installed on the rotor through a screw rod. The gap between the rotor and the screen drum can be adjusted. The coarse screen rotor adopts a drum-type external rotor wing structure and corrects the dynamic balance. This structure can prevent impurities from winding the rotor and affecting the normal operation of the equipment.

　　3. Shell: It is composed of an upper cover and a cylinder. The lower part of the cylinder is equipped with a tangential slurry inlet pipe. The middle of the cylinder is provided with a slurry pipe, and the upper cover is provided with a slag discharge port and a flushing water port.

　　4. Transmission device: including motor, pulley, v-belt, belt tensioner, main shaft and bearing.
