Installation Adjustment and Test Run of Vibrating Screen
① Before the machine is installed, first check whether the parts are complete and damaged according to the delivery list. The vibrator must be re-disassembled and assembled and replaced with clean lubricating oil if it is more than six months from the date of delivery.
② The equipment shall be installed according to the installation drawing, in which the supporting bracket shall be installed horizontally on the foundation, and the foundation shall have sufficient steel degree and strength to support all dynamic and static loads of the vibrating screen.
③Ensure that there is a minimum gap of 50mm between the screen box and the hopper, chute and other non-moving. It is not allowed to reinforce any auxiliary parts on the screen box, otherwise it will affect the screening effect and even cause the screen machine to be damaged or scrapped.
④ Ensure a 10 mm gap between the friction damper plate and the spring seat on the screen box.
⑤ The damping spring is matched according to the free height, so that the free heights of the springs on the left and right sides of the front end or the rear end are as equal as possible, and the error is not more than 5 mm. After the screen box is installed, the screen surface is kept horizontal to the left or right. Otherwise, a thin iron piece should be placed between the spring seat and the support seat.
2. Adjustment and test run
①The spring must be in a vertical state. The contact surface between the spring support and the spring must be in a horizontal state. After adjustment, the spring upper seat is fixed on the sieve box trunnion with a screw, and then spot welded into one.
② Place the motor seat according to the position of the groove wheel on the screen machine, install the position corresponding to the lower leg, and make sure that the groove corresponding to the two belt wheels corresponds to each other in the respective plane, and then weld to death. The motor seat shall not be tilted to prevent the belt from turning, and then the motor shall be set. The belt tensioning shall ensure that V belt tension is fully adjusted.
③ Upon completion of installation and adjustment, no-load operation should be carried out for no less than 2 hours. The operation is required to be stable, no abnormal noise, amplitude and motion track meet the requirements, and the maximum temperature of the bearing does not exceed 75 degrees Celsius.
④After the no-load test run is qualified, the load can be put into trial transfer. The load test time can be carried out according to the process test. Before the test, the hand (or other method) must be rotated flexibly. If there is no jam, the machine can be officially started.
