There was a slight dislocation dislocation in terms of tenths of a millimeter, and equal thickness completely misplaced. Since the pressing roller and the pressing roller positioning instability and in the assembly, with the other parts is not close to zero and so the amount of waste formed by factors Hand test pump Manufacturers will appear axial movement of the pressing roller and the radial wobble, then squeeze rollers will not fit hole caused by lap welding. After the bearing is damaged, it will disrupt the normal position squeeze rollers. Two roller to squeeze roller device, for example, generally have a built-in squeeze roll up and down two sets of bearings, when one set is damaged, squeeze rollers out of control, resulting in higher weld will take welding.
