Shanghai Qinai Machinery has the answer for you: The shaftless screw conveyor is a device that transports materials without a central shaft and relies on the rotation of a spiral. It can be used for transportation in sewage treatment plants and has good environmental performance. The use of fully enclosed conveying and easy-to-clean spiral surfaces ensures that the materials delivered are not contaminated or leaked due to environmental sanitation. Large torque and low energy consumption. Since the spiral has no shaft, the material is not easily blocked and the discharge port is not blocked. Therefore, it can operate at a lower speed, achieve smooth transmission and reduce energy consumption.
Should the shaftless screw conveyor be inspected weekly?
1. Check whether the electrical circuit of the equipment is normal. ?
2. Check whether the equipment is running smoothly and whether there are any abnormal noises. ?
The shaftless screw conveyor should be inspected monthly?
(1) Check the outside and inside of the screw conveyor, and clean the slag in the U-shaped groove. ?
(2) Check whether the spiral is damaged and whether there is axial elongation due to fatigue. When the safety gap between the spiral tail end and the end of the U-shaped groove is less than 20mm, it should be adjusted and locked through the nut on the top of the transmission shaft; when the adjustment amount is insufficient or there is no adjustment mechanism, the excess spiral tail end after elongation can be cut off To ensure a safe clearance and to ensure smooth operation, the spiral tail after cutting must be rounded as it is. ?
(3) Check the wear amount of the lining plate. When the wear amount is greater than 5 mm, the lining plate must be replaced. The spiral is not allowed to directly contact the U-shaped groove. ?
(4) Check whether the equipment is running smoothly and whether there are any abnormal noises. ?
(5) Use a grease gun to add grease to the drive shaft bearing seat.
Half-year inspection of shaftless screw conveyor?
(1) Check whether all bolts are loose. If they are loose, tighten them immediately.
(2) Check the oil level and color of the reduction gearbox. If the oil is insufficient, add oil immediately. ?
(3) Check the axial elongation of the spiral due to fatigue. ?
(4) Check the wear amount of the lining plate. ?
(5) Check the electronic control system and safety device. ?
(6) If the equipment is found to be abnormally worn, it must be repaired immediately.
