Electric pole making machine, namely centrifugal machine, is consist of :the base, roller, bearing, motor, control cabinet and the drive shaft .centrifugal machine is is the key equipment to make prefabricated cement poles . for the connecting shaft, our centrifuge machine adopt pass pole shaft to avoid stress concentration brought by shaft diameter change , resulting in "off-axis" phenomenon; The centrifuge machine wheel wall is removable, making centrifuge repair and maintenance more convenient.
Centrifugal process time is 16min ~ 18min, and now some companies will produce the pole time by centrifugation for 12min, which is the min time limit for centrifugal process, to get qualified products must develop rigorous process system , which should account for 40% of all high-speed centrifugation process,
in order to shorten the centrifugal speed must be adjusted so that the installation of centrifuges accuracy standard, poles precision molds to meet the requirements, to meet the requirements of high-speed operation, improve the density of concrete, shortening the discharging time excess water, centrifugation steel trace appears and allowed jitter is inevitable, such as the beat amplitude is beneficial settling and compacting the concrete, over this range is not normal in the range 5mm ~ 10mm, or even very harmful.
Pole molding system is based on low-speed centrifuge speed → → → high speed of speed.
1) Low-speed (slow): When the concrete slump <when 6cm, its speed of 100rpm ~ 120rpm, rotating 1.5min ~ 2min.
2) Medium: mainly to make equipment and products from shock and vibration impacts, while ensuring discharge excess water slowly and gradually compacting concrete, rotate 1.5min ~ 2min.
3) High speed: the speed of rotation of the molding to ensure discharge excess water in sufficient centrifugal force, and ensure the correct shape speed not less than 360rpm, time 7min ~ 8min
