First, the installation
1. Remove the transport support. Since the base of the screen and the screen frame are connected by springs, the upper half of the screen is firmly supported by the transport support during transportation. After entering the installation site, the transport support should be removed. It is strictly forbidden to take the transport support test machine.
2. The sieve machine should be placed on a level basis when installing. In the case where the foundation is not used, an anti-vibration rubber sheet should be laid between the workbench and the base.
3. The cable in the vibration motor and the screen machine is subjected to severe vibration, and it should be connected to the standard ground wire for safety.
Second, trial run
1. Close the power switch and run for 20-30 minutes. The motor should normally run counterclockwise. If the direction is wrong, please adjust the three-phase power supply.
2. It should be confirmed that the vibration motor is running within the rated current. When starting the operation, especially at low temperature, the current will be slightly higher, but within 20-30 minutes, it should be reduced to the rated current value.
3. The screen machine must not have abnormal sounds. If abnormal sounds occur, it should be shut down quickly for inspection. The abnormal sound is usually caused by the loosening of the fastening parts. Especially when it is assembled after transportation and disassembly, pay great attention to the fastening of each part. The screen has an instantaneous resonance zone (1-3 seconds) when starting and stopping, and the amplitude and noise will increase significantly, which is a normal phenomenon.
4. After the empty operation, a small amount of material can enter the sieve machine through the feed inlet, and then slowly increase to the required and acceptable feed amount. At this time, the weight should be adjusted according to the discharge condition of the mesh surface. In order to achieve the efficiency of the sieve machine.
5. The general materials of this series of sieves are not equipped with bouncing ball devices, which can meet the screening requirements. Special materials need to be equipped with bouncing ball devices to be designed and installed separately. At this time, the no-load noise will increase.
6. Adjustment of the phase angle of the upper and lower weights of the motor
Third, change the phase angle of the upper and lower weights, you can change the movement track and residence time of the material on the net. In order to adapt the screen machine to the separation state required by various materials, such as material distribution, processing volume, separation efficiency, and network rate, it should be adjusted to the good state.
Note: The running directions of the two motors are reversed! Both motors can run inward at the same time or both at the same time.
1. Adjustment of the motor phase angle. The phase angle of the upper and lower weights is reduced or increased. Its function is to increase or decrease the exciting force of the screen machine. The vibration force is increased or decreased according to the number of layers of the user's sieve machine and the specific gravity of the material. The weight phase angle of the hammer can achieve the effect of Zuijia screening. The phase angles above and below the motor must be the same.
2. The inclination of the sieve machine is 4° -10°. Sometimes due to the influence of parameters such as specific gravity, humidity, stacking inclination angle, etc., the above adjustment phase is impossible to adjust once, so the user should have sufficient patience to adjust to make the sieve machine perform its high efficiency.
Fourth, daily inspection and maintenance
1. Carefully check the fastening bolts at each joint of the screen machine for looseness. If it is loose, it will cause damage to the screen.
2. There is no wear on the wiring from the vibration motor to the switch. When replacing the cable, use a neoprene vibration-resistant cable. It is strictly forbidden to operate.
3. Check the motor for abnormal sounds and abnormal heat. The temperature limit of the motor bearing part is 40°C higher than the ambient temperature. If it is not normal, add lubricating oil (Shell, Avanti, RL3 grease), or replace the bearing. The decoration of the motor should be carried out by a skilled technician.
4. Whether the screen is tensioned, whether the mesh surface is damaged, if there is damage, change the net in time.
5. The sieve machine must be cleaned up after each use.
Five, screen replacement
1. If the screen is damaged and needs to be replaced with a new one, just remove the external locking handle, remove the screen, take out the screen frame, remove the rubber seal, tighten the bolt, and loosen the screen frame. The damaged screen can be replaced by tightening the bolts.
2, then put on the new network, re-install in 6.1 reverse order. Note: The net must be flat and sturdy. First lock the lower bolts of the screen frame and then lock the upper bolts. The two outer V-groove bolts must be tightened.
Sixth, equipment maintenance
1. Always refuel when the equipment is running, refuel twice a week, injection shell, love Wanli, RL3 grease.
2, every three months to carry out a minor repair and maintenance, 6-12 months for a major overhaul, inspection of the motor during maintenance, whether the fasteners are loose, open the vibrator to clean the bearings, oil seal, wear should be replaced .
3. Check the cable regularly (change the motor lead three months)
