How to solve inflexible rotation problem of conveyor roller

How to solve inflexible rotation problem of conveyor roller

To ensure accuracy during conveyor roller manufacturing process 

Such as the inner hole precision of punch bearing housing should reach grade 3, dimensional tolerance,coaxial degree and ovality of the pipe body two ends must conform to the national standard,can not exceed the tolerance. 

Sealing and lubrication

in addition to ensure the quality of manufacture, also require better lubrication materials, such as lithium base grease which can improve the bearing lubrication performance, this is very necessary to prolong the service life of roller.

Bearing seat adopts labyrinth seal structure of centripetal ball bearing supporting and plastic sealing ring, which can guarantee reasonable bearing stress of roller during operation,but also ensure good dust prevention effect, small resistance, and convenient installation and easy maintenance, it can effectively reduce the conveyor operation cost at the same time.

How to Select Vibrating Screen Coupling

How to Select Vibrating Screen Coupling

Coupling is being used to connect two shafts to make them conjoined and deliver torque. It is a universally mechanical transmission component. As the vibrating screen coupling is standard component, users can choose appropriate one during use according to national standards.

Influenced by manufacturing, installation error and temperature variation, two shafts connected by coupling cannot be centring. In this case, it’s better to select cross coupling between reducer and clutch. This kind of coupling consists of one half coupling with a rut and one telophragma with protruding teeth both sides. Because the protruding teeth can move freely in the rut, it can compensate for the relative displacement between the two shafts. This kind of coupling can be made of 45# steel. And it’s better to make heat treatment in the working surface so that it can improve its hardness.

When it is put into use while two shafts has relative displacement, telophragma will generate large centrifugal force and then it will enlarge dynamic load and wear. Thus, users have better notice that working speed of this machine shall not be more than rated value.

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.
