Focus on Unbalance Motor Vibration on Vibration Platform

Focus on Unbalance Motor Vibration on Vibration Platform

Vibration platform is not the vibrating device as what you imagine that it is not just added several springs and vibration motors. During actual production, it needs to be treated seriously. Here PK Machinery wil explain the unbalance vibration phenomenon of motor in vibration platform.

What problem users cannot address is that uneven and unbalance of vibration during operation of vibration motor. This unbalance vibration generates less effect on screening device, while it will occur frequently during making the vibration platform. However, users often ignore the unbalanced vibrating force of vibration device.

1.It will exist motor rotation during application of single vibration motor on the vibration platform. And it will cause materail moving on the surface of vibration platform.

2.It will change the phenomenon of uniform vibrating point if two vibration motors are put into use. Because of counter rotation of two motors, it can offset vibrating power in the middle vibration platform. If vibration amplitude around table is 5mm, then vibration amplitude in the central point cannot be more than 3mm.

View Tips: Daily Maintenance of Motorized Pulley

As the power of belt conveyor and other lifting equipment, the daily care and maintenance of motorized pulley are very important. Compared with other reducing mechanism, motorized pulley has advantages of sample structure, small volume, easy installation and so on. Here PK Machinery will introduce this kind of knowledge for you. Hope you can have a better understanding.

1.Users had better check the surrounding environment, fastening bolt, situation of oil leakage before start operating so that it can create a better condition for normal operation.

2.If users put a new motorized pulley into use, it's better to check the vibration of whole machine, noise and the temperature of all spare parts after 10 minutes' operation.

3.Please check two parts if there is the situation of oil leakage: one is oil seal, check whether the oil seal is wore or out of shape; another is that the air outlet cannot be blocked, users had better clear away dust, oil contamination and other impurities if there is the phenomenon of blockage.

What You Should Know About Vibrating Feeder

What You Should Know About Vibrating Feeder

Vibrating feeder can evenly and continuously transport materials from storage bin to receiving hopper. So it can be widely used in coal,metallurgy,mineral separation,etc. But how to use vibrating feeder safely, the notices are as follows:

I.Lubrication

What users should know is that regular maintenance and overhaul can not only prolong lifespan of machine, but also ensure normal work. And users should pay attention to the following notices:

1.Based on the different use place and temperature, users should choose different  lubricating oil, and generally it should be gear oil.

2. Make sure that the height of thin oil in vibration exciter should exceed oil leveler. And the oil should be changed new one per three to six months.

II.Pay Attention to Safety Technology

1.Never operate machine if the machine operators do not learn the knowledge of safety technology.

2.It is prohibited that there is someone standing beside machine during operating.

3.Users should check amplitude of vibration motor. If there is something wrong, please turn off machine right away and maintain it.

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.

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.

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.
