The application of screw conveyors has greatly improved the production efficiency of the factory. In order to prolong the service life of the machine, regular maintenance in use is also essential. Today, our Fanxi Environmental Protection Screw Conveyor Equipment Factory Introduce several maintenance methods for screw conveyors.
Shaftless screw conveyor is a kind of equipment of screw conveyor, which is a conveying equipment without central axis. Compared with other screw feeders, it will not produce viscous materials. What is the key to regular warranty maintenance for equipment like ours? In fact, any equipment needs to be customized for maintenance. These maintenances have a certain period. Small maintenance and large maintenance are popular in the market. The following is an introduction to the weekly, monthly, and annual maintenance points of the shaftless screw conveyor.
Key points of precision maintenance:
The weekly maintenance of the conveyor is relatively simple, mainly to check whether the electrical circuit of the conveyor is abnormal, whether the power is normal, and then whether it is stable during operation, and whether there is abnormal noise during rotation. These little things
Monthly maintenance points:
* Check the inside and outside conditions of the conveyor, and clean the inside of the trough;
* Check the wear of the liner. If the wear is severe enough to approach or exceed 5 mm, be sure to replace the liner with a new one.
* Use a grease gun to inject a certain amount of grease into the drive shaft housing to make the drive shaft have a good transmission effect.
* Check whether the conveyor is running smoothly and whether there is any abnormal sound.
* Check the wear of the propeller blades, because fatigue can cause vision and axial stretching. If the safety distance between the end of the thread and the end of the U-shaped groove is less than 20 mm, it should be adjusted by bolts and locked on the top of the drive shaft. Assuming that the number of settings is insufficient or there is no regulatory tissue, the additional end of the spiral tail can be removed after stretching to ensure a safe interval. In order to ensure the smooth progress of the work, the cutting end of the propeller should be rounded according to the forward attitude.
Main points of annual maintenance:
* Observe the oil level of the conveyor and the color of the reducer. If the oil is not enough, water should be filled immediately. The reducer oil must be replaced regularly; if the reducer oil is used, it needs to be replaced for 300 hours; in normal operation, the reducer oil should be replaced every 5000 hours; the quality of the oil must be checked regularly according to the oil standard positioning; the reducer oil must be as specified Position conveying, not mixed with various oils; the brand and viscosity of the oil should be consistent; during work, if the oil temperature control is abnormal, the noise is abnormal, etc., the work should be stopped immediately, the cause is found, the fault is eliminated, and the work is continued; If there is a quality problem with the reducer oil, you should contact the manufacturer or supplier in time and do not disassemble it.
* Check whether the bolts of the equipment are tight, if they are loose, they need to be tightened or reinforced.
* Check the degree of wear of the liner carefully. If the thickness of the liner is close to 2 mm, it should be replaced in time.
* Observe that the spiral is a state of axial elongation caused by fatigue.
* If abnormal wear of the conveyor is found, it should be shut down immediately for maintenance.
* View electronic control equipment and safety equipment.
* The normal working environment temperature of the reducer is -30~40℃. If the temperature is too high, some cooling measures must be taken.
* The reducer is required to be equipped with a magnetic starting device and used within the executable torque range to avoid damage to the motor and reducer.
Because of its good conveying performance and low cost, screw conveyors have been widely used for conveying small bulk materials such as grain, feed, food, building materials, etc. As long as the main points of equipment maintenance in weeks, months and years are mastered, the equipment can be guaranteed to be used The cycle is long.
