Pay Attention to the Unbalance Motor Vibration Phenomenon of Vibration Table

On the surface of it, vibration motor will become a veritable vibration equipment, just need plus a few springs on the equipment, and put on a few motors, then it will be applied for vibration production? While it’s more difficult than what you see. Now PK Co., Ltd will give you the further insight about the unbalance vibration phenomenon of the vibration motor for vibration table.

The problem of uneven and unbalance that causes the vibration can never be solved when the vibration motor is running in the equipment. There is influence of the unbalanced vibration in the screening equipment, however, in the process of making the vibration table, the problem usually happens. We also always take less importance to the problem of the unbalanced force of vibration equipment in reality.

1.The problem of motor rotation can happen and the material will move on the surface of vibration table in the use of a single vibration motor on the vibration table.

2.The uniform vibration point of the vibration table will be changed in the use two vibrating motors. The counter rotation of two motors will result in the power counteraction in the middle of the vibration table. The vibration amplitude in the center of the table can’t be over 3mm if the vibration amplitude around the platform is 5mm.

What reasons lead to linear vibrating screen motor base crack

What reasons lead to linear vibrating screen motor base crack

All users know that the vibration motor is the vibration source of linear vibrating screen , it will bring inconvenience of operation if the vibration motor base cracks and damages. Here are some analysis reasons for you:

1. Too large motor power ,model selection and exciting force which exceed the normal load of vibrating screen, it will cause damage of motor base for long time operation

2. Too thin steel plate thickness design with long time operation will cause crack.

3. There is a problem with steel plate material.

4. Welding quality can not meet the requirements.

5. The installation position of the motor does not conform to the design requirements of the vibration dynamic specifications.

Introduction of Motor IP Grade: The meaning of the second number

Introduction of Motor IP Grade: The meaning of the second number

0: no special protection
1: drip-proof: vertical drop of water will not directly enter into the motor.

2:15 degrees angle drip proof: within a range of 15 degrees angle, water drop will not directly enter into the motor. 

3: 60 degrees angle water spray proof: within a range of 60 degrees angle, water-spray will not directly enter into the motor.

 

4: water splash proof: splash water in any direction will not bring harmful effects to motor.

5: water spray proof: spray water in any direction will not bring harmful effects to motor.

6: water waves or strong water spray proof: furious waves or strong water spray will not bring harmful effects to motor.

7: water immersion proof: motor immersed in the water under a stipulated pressure and time, the water inflow will not bring harmful effects.

Introduction of Motor IP Grade :The Meaning of First Number

Introduction of Motor IP Grade :The Meaning of First Number

Motor IP (INGRESS PROTECTION) grade system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION ).IP grade is composed of two numbers, the first number represents for anti-invasion grade of external objects and dust, the second the number shows that the sealing degree of anti- invasion of moisture and water, if the number is greater, the degree of protection will be higher.

0: no special protection

1: it can prevent external objects with solid diameter larger than 50 mm entering into the casing. 

2: it can prevent external objects with solid diameter larger than12 mm entering into the casing. 

3: it can prevent external objects with solid diameter larger than 2.5 mm entering into the casing. 

4: it can prevent external objects with solid diameter larger than 1 mm entering into the casing. 

5: protection against dust, it can prevent dust from entering to affect the normal operation of the product, and prevent dust contacting the inner casing or parts.

6: sealing against dust, it can completely prevent dust from entering into the casing and prevent the dust contacting the inner casing or parts.
