The Relevant Parts Of Shotcrete Machine Maintenance

1.Method of turning and grinding of sealing plate?Concrete gunite machine: In order to avoid sealing plate deformation in the repair process, available a magnetic clamping plate or rigidly fixed disk the sealing plate clamped to a lathe, hard alloy cutter is used to turning surface about 2 – 3mm deep, until the deep scars disappear. Then the rubber grinding covering 2 – 3 times by grinding device or porous wheel rotation. Steel reinforcement section must be below the sealing surface of the plate approximately 2mm. Rotate speed of workpiece when repairing: 200r/min Grinding wheel speed: about 1600r/min Feed rate – grinding wheel or hard alloy cutter 0.2 – 0.3mm/r.
2. Method for repairing rotor lining plate?Dry mix shotcrete machine With the delicate chisels the lining board and the rotor separated, never use a heavy hammer or other tools to beat, so as not to damage the especially hard and brittle rotor liner. To thoroughly clean the surface of the lining and the rotor. Surface grinding plate, until the scars disappear. Liner to the rotor installation, first pin inserted into the drilled positioning pin holes, below the surface of the lining plate 1 ~ 1.5mm, should be particularly careful not to enable pin above the surface of the lining plate, in order to avoid damage the rubber sealing plate 3. Method for repairing rotor The rotor is removed from the main shaft of the reducer, and the plastic material cavity is pulled out from the rotor. Thoroughly clean the rotor, turning the rotor end face, until the scars disappear, check the plastic material cavity, if there is damage, should be re – replaced, to pay special attention to the material at the end of the O – shaped seal ring.
