大发彩票 www.paulmartinezmusic.com Ya range of circle vibrating screen box the trajectory of a circle, applies to coal, limestone, crushed stone, gravel, metal or non-metal ores and other materials screening.
The working principle and structure characteristic
This series of sieve is mainly composed of screen box, screen, vibration and shock absorption spring and so on.Vibrator mounted on the side of the screen box on the Board, and by the adoption of V-belt drive motor rotation produces centrifugal force, forcing the screen box, vibration.
If the user does not have special requirements, YA and 2YA type of textile screen surface, ya for punching sieve surface, all kinds of screen surface can meet the high screening efficiency, long life, non-block or requirements.
The series screen to base type installation.The adjustment by changing the inclination of sieve surface the height of spring support positions to achieve.
Motors can be mounted on the left side of the screen frame, can be mounted on the right side of the screen frame, in the absence of specific requirements, the installation of the right side of the factory according to the direction of the movement of materials supply.
Installation and debugging
The installation should be in accordance with the requirements of drawings of pre-embedded steel plate, the requirement of pre-embedded steel plate in the same horizontal plane on the plane.Install the required pre-embedded steel plate foot bolts are owned by the sector.
Each screen of the selection of support spring should be carried out prior to installation to ensure all the same height and stiffness of the spring.
After the factory vibrating screen, such as the installation of more than 6 months, the bearing before installation must be within the vibrator to remove for cleaning, new lithium-base grease lubricating grease (No. 2).
Vibrator by re-installed, rotating the eccentric shaft there shall be no resistance by hand is too large or the phenomenon of death, or should be adjusted timely find out the reasons.
Motor pulley groove must be aligned with the screen box, vibration of belt pulley groove, parallel to each other.
After the installation of the various components of vibrating screen, After passing the acceptance check can be commissioning before commissioning a detailed examination of all the bolts are secured, whether it hinders the screen frame around the screen vibration of the obstacles.
Test run for 4-6 hours, observe the operation of screening machine, if it is found that the phenomenon of abnormal sound or vibration loss of ambition, should immediately stop checking reasons, troubleshooting.
-In 4-6 hours you should check the following items:
1, The bearing vibration temperature, the requirements of the highest temperature of more than 75 degrees Celsius, the temperature rise of not more than 45 degrees Celsius.
2, The fastening bolts of all, it is found that the tightening loose a timely manner.
After the commissioning of vibrating screen can be put into production.Within two weeks after the machine is put into production, should be retightened the bolts throughout the week again, after fastening a month at a time.
Use and maintenance
Should not the case of material in the sieve shaker to start, try to avoid starting with material, after smooth running machine in order to feed.Need to stop feeding before the shutdown, to be shut down again after the exclusion of surface materials.
In the course of work should always observe the operation of screening machine, for example, found that the motion is not normal or abnormal sound, should be shut down to check and find out the reasons, troubleshooting.
Vibration of bearing lubrication of lithium grease 2, in normal circumstances, each of the two grease to add a long time, the filling-up quantity is not too much, otherwise it will cause overheating of bearings.Vibration after 6 months of use, check the status of oil, for example, found that when dry or hard lump, should be cleaned to replace oil, the bearings should be clean and check each year at a time.
When ordering, please specify the types, the number of screen surface layer, the material name, size, screen size and other parameters.And please specify mounting position, the meaning of left and right fit.
