Equipment structure and work principle
1.equipment composition: it is made of track underbed, grinding head dolly( 2sets),revolving roller device( 2sets),wet centrifugal dust scrubber device (2sets), air operated system, electrical control system.
2. Equipment parts structure and working principle:
2.1 Track underbed part:
Track underbed part made of welded merchant steel,lay the heavy rail on it in order to guide the grinding head dolly and raw material pipe roll driving device.
2.2 Grinding head dolly part:
Made of dolly, grinding head subassembly, dolly driving device
2.3 Raw material pipe roll driving device:
Made of roller, stock stop,roller driving device, roller gap adjustment device and safe shade plate.
2.4 use web dust remover(2 pieces),fan power:5.5kw
This dust remover was put both sides of steel pipe,the machine appearance is drum shape, built-in fan, cyclone separator and dust collection bucket.to make the dust air and water form cyclone and produce continuous fog water vapor which absorb the dust in the air. The dust remover has the property of high efficiency, low noise,compact structure,move easily,long service life,easy maintenance and so on. Water wastage in 24h is 0.2CBM.
2.5 air operated system:
Make the grinding head float with pipe bending under certain pressure so that the grinding wheel close to the inner surface of the pipe.
2.6 Electrical control system:
Electrical control system composed of PLC control system.
(1) PLC control system mainly used in craft logic protection, equipment alarm and fault display.
(2) Used in the overload protection of grinding head electric machine, dust collection electric machine,dolly moving electric machine, opening and closing electric machine,wheel driving electric machine etc. The relevant part of equipment will stop moving when fault or craft logic mistake and the trouble light shown on the operating floor face plate.
The button, indicator light on the operation panel are both from Siemens in order to keep the quality, roller rotation speed adjustment adopted knob adjustment so that quick and convenient operating.
2 sets of grinding head electric machine operation monitoring system made of 2 pieces of DM94C digital amperemeters. The operator can monitor the grinding head operation and make the steel pipe surface better.
(3)Low voltage electrical component come from Siemens, Omron.
(4) PLC from Siemens S7-200 CPU226XP
(5) frequency converter from Siemens MM440 vector frenquency converter.
We also engaged in tube testing machine, elbow pushing machine, pipe beveling machine, pipe internal and external grinding machine with patent too. All of them are the best quality with reasonable price. Welcome to visit our factory.
