Concrete vibrator motor exciting force is too small adjustment method Vibration motor excitation force is too small is a lot of vibration machine users often encounter and how to solve this problem. In fact, the vibration motor excitation force at the factory were raised 80 percent, mini cement mixer cm140 for sale price required shipping (export) exciting force raised to 0%. So that when used according to the following steps to adjust: 1, the horizontal vibration motor: (1), loosen the fastening screws protective cover, remove both ends of the shield; (2), the exciting force is less than MV50-2, MV50-4, MV50-6, MV30-8 vibration motor (does not contain this four specifications), outer eccentric adjustable block, surface mounted indicating maximum excitation force percentage scale, within the eccentric block is a fixed block, use the fastening bolts on the motor shaft pressed. Both end surfaces of the shaft engraved reference line. Loosen the outer sides of the eccentric clamping bolt, the outer sides of the eccentric rotates in the same direction, so that the shaft groove aligned exciting force eccentric ruler engraved lines on the outside, to the required excitation force, tighten the outer eccentric block bolts, fitted with protective cover; (3) exciting force is greater than or equal to MV50-2, MV50-4, MV50-6, MV30-8 vibration motor (including this four specifications), outer eccentric fixed block, is keyed on the shaft, can not be rotate. Adjustable eccentric block within the block, the outer surface of the exciting force is equipped with the largest percentage indicated ruler, using a fastening bolt is pressed against the motor shaft. Loosen inner eccentric bolts on both sides, both sides of the eccentric rotation in the same direction, so that the exciting force eccentric ruler engraved why twin-shaft concrete mixer lines is aligned within the outer eccentric slit to the required excitation force, Tighten eccentric bolts, fitted with protective cover; Note: Except for special applications, the position of the motor shaft at both ends of the eccentric vibration must correspond to both ends of the eccentric set percentage must be equal, otherwise the vibration motor generates a huge mistake to exciting force, vibration motor mechanical damage . 2, vertical vibration motor: (1) exciting force adjustment: Remove the additional block bolts to adjust the excitation force by increasing or decreasing the number of additional blocks; Adjustment (2), under the eccentric angle: the eccentric block is a fixed block, the next block is an adjustable eccentric block, use the fastening bolts on the motor shaft pressed. Both ends of the shaft surface engraved with the baseline, under the eccentric rotation angle with the outer surface of the scale indicated, Panasonic rotary eccentric bolts, under the eccentric rotation, the angle on the scale at the eccentric shaft aligned with the benchmark engraved reticle line, adjusted to the desired angle, tighten down eccentric bolts; To adjust the angle of the eccentric, the method can also be adjusted accordingly. 3. Connect the power A vibration motor cable due to withstand vibration, so should be used in heavy-duty four-core cable, do not allow a sudden bend near the cable exit, have a 8-9 times greater than the cable diameter bend radius, and then the cable is not fixed to a stationary moving machine or frame. A distance of approximately 0.6 m to 0.9 m. In the clip of the cable should be fixed pad with soft insulating material, so as not to damage the cable friction. Four-core cable ground wire, one end of the junction box grounding screw is connected to the other end must be grounded. Small size vibration motor, the chassis is no junction box, using heavy three-core cable connection directly from within the motor. In the vicinity mini concrete mixer price of the motor feet fitted with grounding screw must be grounded when in use. Note: The vibration motor cable outlet for the wearing parts, often due to vibration friction damage, resulting in motor phase operation, damage to the motor. Users should regularly check the cable condition, if worn should be replaced with type cable. Try to do it once every three months plus oil, if used for too long (as appropriate to add)
