Disc feeder capacity adjustment methods and common faults introduced

1 base type and suspended disc feeder comparison
Docking disc feeder : the need to build a foundation, while supporting the poor machine , the user generally formulated weight feeder port , adjust sets, scraper plate , retaining plate

, etc., so this disc feeder installation costs high , the installation time-consuming , and because the mounting base 's sake, craft

Arranged by the very limited flexibility .
Suspended disc belt weigh feeder : improvement on the whole package , but installing the beams need special preparation , but the structure is also complex and difficult to implement

multi-port discharge .
2 disc feeder capacity adjustment method
( A ) adjusting scraper plate position: Turn the handwheel can be completed and passed through the screw shaft scraper pointer pointed scraper plate position .
( 2 ) adjust the cutting height of the sleeve : Turn the handwheel completed through cutting sleeve screw height adjustment .
( 3 ) adjust the motor speed : When the DC motor as the drive, the motor speed can be changed to adjust .
3.PDX disc feeder
PDX new disc feeder adopts advanced Hardened reducer drive, frequency control system, large diameter slewing ring , unique drive under seal and new controllable gates , its

energy consumption is an ordinary disc feeder 1/3. PDX new disc feeder adopts the most advanced plane

Double enveloping worm gear form .
PDX new disc feeder features:
( 1 ) using the easy sealing , hanging material short tube , to prevent discharge of materials for a long time and can not be cured successfully discharged .
( 2 ) the adoption of new material layer can be adjusted to control the gate , you can easily set the size of feeding amount , convenient adjustment , adjustment range.
( 3 ) the use of large diameter slewing ring structure , particularly large carrying capacity and can withstand more than 15 meters long material pressure tank mine life of 10

or more .
( 4 ) transmission structure , high reliability, long life, as used in all hardened gear transmission, the transmission efficiency is particularly high, up to 95%.
( 5 ) the transmission part of the lubrication conditions, gear, slewing bearings, pinions, etc. main drive mechanism , the use of high-quality high viscosity extreme pressure

type of load gear oil lubrication , to ensure trouble-free operation of the disc .
( 6 ) The transmission system adopts unique sealing structure to ensure that no part of the transmission mechanism lubricated entry of foreign matter .
4 disc feeder common faults and handling
( 1 ) Operating temperature mechanical
Disc feeder after 4 hours of continuous work temperature rises rapidly, the worm bearing cap and the body surface temperature can reach 89 ℃ or so , machine for a long time at

high temperature operation.
( 2 ) reducer casing serious oil spills
Because of high oil tank , oil level hole plexiglass perspective deformation , combined oil dilution , leakage serious , the most serious leakage can be achieved by the amount

of 2kg / h.
( 3 ) Worm badly worn
Worm transmission parts strong enough force caused due to box deformation, resulting in displacement of the axis of the worm two of cabinet intensity strengthened. First, the

worm drive increases the thickness of 12mm parts of three ribs ; two ends of the worm is the main load bearing parts

Increase of two reinforcing plates , so that the design to ensure the strength of the cabinet .
( 4 ) disc positioned well, when working with a load , affecting the normal worm engages the center of the turntable adds a set of positioning bearings, the bearing model for

2260 , so that from the design to ensure the disc center pair.
( 5 ) in the processing center of the worm and worm center has an offset in the spatial orientation , affecting the normal engagement , the finishing and assembly should be

performed during a tight tracking and control to ensure that the worm shaft holes two concentric , and the worm into port for grinding 0.10-0.15mm, thereby increasing Nie

Combined area smooth transmission .
Lubricant selection unreasonable design selected lubricant grades for the 20th and the 30th gear oil , because the viscosity is not enough, the worm can not form a film on the

meshing tooth surface lubrication conditions are not good , exacerbated by tooth wear , re-select lubricant. In the test has selected 200 ordinary

Industrial gear oil , and its kinematic viscosity range of 180-220 centistokes . Put into use after use 633 oil , and its kinematic viscosity in the range 288-320 centistokes ,

thus radically improving lubrication of worm .
( 6 ) disc feeder in the overall installation process, based on the bottom is not leveling ( maximum error has 12mm) is caused by a major reason for poor meshing , the process

should be installed in the field , and strictly control the level of the underlying platform to find positive , the original underlying platform is not level in the north-south

direction , the maximum error of

To 12mm, the error after leveling control 5mm / m or so.
