Several Ways to Solve Vibration Motor Frequent Trips

Several Ways to Solve Vibration Motor Frequent Trips

Most users know basic operation of the vibration motor. But during operation, there are many notices that we need pay attention, especially the frequent trips of vibration motor. Here PK Machinery will analyze the reasons of frequent trips and how to solve them for your reference: 

1. With regards to vibration motor air switch, if over-current protective device is unconformity, please replace it timely.

2. If motor cable is worn, this is mostly caused by wear and tear over time. Users can wrap it around by adhesive tape. 

3. Bearing is damaged or lack of oil so it will trip due to overload. Then users need to replace bearings timely. 

4. There is something wrong with vibration motor power or breaker aging. 

5. The magnetic circuit performance of the vibration motor declines, resulting in excessive current. 

Above mentioned points are the common reasons, and it is easy to deal with. As long as users find corresponding reasons, then adopt the corresponding methods, the problems can be resolved. If the vibration motor frequent trips are not caused by the above circumstances, please contact us promptly, our technical engineers will offer the help.

Introduction of YZO vibration motor

Introduction of YZO vibration motor

YZO vibration motor has a extremely wide application scope in many engineering projects as it is a universal type of motor, such as the vibrating equipment used in hydropower construction, building materials, chemical, mining, coal, metallurgy industries etc. The vibrating equipment includes vibrating crusher, vibrating screen, vibrating packing machine, vibrating shake-out machine, vibration molding machine.

The exciting source of YZO vibratory motor is produced by power source and vibration source, the exciting force can be adjusted steplessly and it is easy to operate. 

YZO vibrator motor is not only can be applied in general vibrating equipment, but also can work in the forms of a combination of a variable vibration types, such as planispiral, spiral, shaking vibration, combination straight line, combination of long elliptic,compound double amplitude ,these vibration forms can produce new vibration equipment.

 

Common Troubleshooting Methods of Vibration Motor

Common Troubleshooting Methods of Vibration Motor

1. after connect the power supply, motor is unable to start, please check:
(1) if power supply is lack of phase;
(2) if motor is loss of phase;
(3) if protective cover is damaged or rub eccentric block.

2. after start-up, there is big motor noise or motor heats, please check:
(1) if the contact surface roughness of vibration machine and motor foundation is in line with the installation requirements;
(2)if the anchor bolts are not tighten up ;
(3) if the vibration acceleration is in line with the requirements;

3. after the adjustment of eccentric block, amplitude changes abnormally please check:
If eccentric block on both ends of the rotor axis is symmetrical.

4. when two vibrating motors of vibration machine vibrate at the same time, if its phase does not conform to the requirements, please adjust the phase sequence of the single unit, don't adjust the total phase sequence of two vibrating motors.

How to Identify Counterfeit and Genuine Bearings of Vibration Motor

How to Identify Counterfeit and Genuine Bearings of Vibration Motor

As the power source of mining machine, it is very important to identify counterfeit and genuine bearings of vibration motor. Otherwise it will affect the normal operation of mining machinery. So it needs us to pay attention.

Due to the special structure principle of vibration motor, the quality and lifespan of vibration motor directly affected by bearings, of course will be embodied in the price level of vibration motor. So it is really necessary to choose a good bearing manufacturer, the following methods will help us identify counterfeit bearings:

1. Packaging

Formal original packing of genuine bearing is comparatively normative which includes inner and outer packaging with unified standard and clear writing. However, the counterfeit bearing packaging material is inferior, printing is rough.

2. Color

Specific parts of genuine bearing present a certain color, for example: chamfer is black, if there is any other colors, it may be counterfeit bearings.

 

3. Appearance 

The writing letters of genuine bearing outer packing adopt special carving or spraying technology design, however, the counterfeit bearing printing is blurry.

4. Material 

Material selection of the genuine bearing is standard steel material, however counterfeit bearing adopts cheap ,fake inferior and unqualified material in order to reduce the manufacturing cost, the weight is light.

5. Processing technology

Genuine bearing manufacturing process is fine which can rotate smoothly However counterfeit bearing manufacturing process is poor with coarse surface ,it can not rotate smoothly.
