Since the working principle of the vibration machine is special, the use method and daily maintenance are more important! Dehydrated shaker is no exception! Improper use or improper maintenance can greatly affect the service life and production efficiency of the dewatering shaker! Xinxiang Sanjiang Vibration summarizes some methods for proper use and maintenance of dehydrated vibrating screens, please refer to the users!
1. When the dewatering vibrating screen is shipped from the factory, the exciter is filled with lubricating oil and has anti-corrosion performance, which is valid for three months. After the storage period is more than three months, it will run for 20 minutes, and it can continue to be preserved for three months. It must be replaced with clean lubricating oil when working.
2. Ensure that the tank is filled with grease. If working under dusty conditions, the grease should be added more frequently.
3. The normal operation of the bearing should not exceed 75 °C. The new exciter may have a slightly higher temperature because of a running-in process. However, after 8 hours of operation, the temperature should be stabilized. If the temperature continues to be too high, the level of the oil should be checked. Oil level and oil cleanliness.
4, always keep the vibration of the exciter vents (leading to oil leakage due to blockage). If there is still oil leakage after unblocking, the oil seal should be replaced.
5. The bolts connecting the exciter and the screen box are high-strength bolts. It is not allowed to replace them with ordinary bolts. The tightening condition must be checked regularly, at least once a month. If any one of the bolts is loose, it will cause other bolts to be cut and cause damage to the screen.
6. When replacing the V-belt, the motor anchor bolt should be completely loosened, and the V-belt should be conveniently placed in the pulley groove. The V-belt should not be used with sticks or other objects. The tension of the V-belt must be suitable. Pulley Must be aligned, after the first adjustment of the tension, work for 48h, and then adjust again.
7. Where the ring groove rivets are used, it is allowed to be replaced by high-strength bolts. All contact surfaces or holes should be free of iron filings, ash, oil, rust and burrs.
8. When the flame is cut, stress will also be generated around the cutting surface. Therefore, it is recommended that any additional holes on the screen box should be drilled.
9. In order to prevent internal stress caused by welding, it is generally not allowed to weld the screen box and any auxiliary parts on site. When welding, it should be carried out by skilled operators. The following steps are recommended.
(1) To prevent crack propagation, a hole of 6 mm diameter was drilled at each end of the crack.
(2) Shovel the groove along both sides of the crack with a round shovel.
(3) Preheating around 60 °C first, using 3mm diameter welding rods (corresponding grades), and preventing any slag inclusions and biting.
(4) Smooth the solder on both sides and weld the reinforcing plate.
(5) If it is necessary to weld on the screen bracket beam, all welds shall be parallel to the beam and shall not be welded laterally.
(6) When using AC welding, the screen box should be grounded to prevent current from passing through the bearing, otherwise it will easily cause damage to the bearing.
10. The high-strength bolts, nuts and washers used must meet the requirements of "Technical Conditions for High-strength Large Hex Bolts, Large Hex Nuts and Washers for Steel Structures".
11. When disassembling the dehydrated vibrating screen , carefully remove it from the outside to the inside to avoid artificially damaging the parts. In particular, when disassembling the balance wheel, the disassembler must be used. The removed parts should be cleaned one by one and carefully inspected. If damage is found, it should be repaired or replaced in time.
12. When replacing the woven screen, ensure that there is an equal gap between the two sides of the screen box and the screen hooks. First tighten the middle flattened flat steel, and pull the tension tight plate to keep the surface tension of the screen even and hammer. Gently tap along the full length to check the tension. If the contact is not good, the tension is not enough or uneven, it is one of the important reasons for the premature damage of the screen.
13. The tensioning plate guide angle steel is adjustable. When installing the screen, first loosen the guide angle steel bolts so that the upper and lower can move. After the screen is placed, first tighten the tension bolts to give the tension plate a slight pressure. Then, drive the angle steel until the screen abuts against the screen bracket, and then tighten the steering angle screw.
14. The length of the screen hook strip must be the same as the length of the tension plate. When the screen aperture is less than 16mm, the screen should have a 20mm extension at the end.
15. Between the braided dehydrated vibrating screen and the screen bracket, equipped with a special vibration-damping rubber strip. In order to achieve the longest service life of the screen, the rubber strip should be properly located between the two. Damaged rubber strips should be replaced in time.
