Prevention of Bearing Damage

Bearing is the essential parts in a vibrating screen. When there is problem with the bearing, the vibrating screen unable to operate as usual. Normally, continuous vibrating of screening surface can cause damage to bearing. How we can prevent the damage of bearing under normal operation of vibrating screen? Let’s us share with you the knowledge.

The eccentric block may fall down due to long-term operating or abnormal rotation speed of equipment. This all are known as abnormal situation of an operating vibrating screen. This abnormal situation can easily cause bearing abrasion. In this scenario, we need to change the layout of eccentric block regularly to balance the working of equipment. The abnormal rotation speed of bearing will lead to increase of temperature. When there is crashing between bearing and the body of vibrating screen, it will caught on fire.

Lubricating oil needed to be added regularly on bearing and motor. Inappropriate amount of lubricating oil added can cause abrasion as well. Excessive amount of lubricants added might increase the temperature of lubricants oil and the sealing ring of bearing will be blocked. This scenario can be avoided by regular maintenance and inspection on bearing and vibrating screen. Besides, the lubricant needed to be in clean situation. If there are impurities, the lubricants needed to change immediately. The damage of sealing ring and bearing abrasion affects the bearing operation. When the sealing ring breaks down, we must change it immediately and make adjustment in other parts of vibrating screen.

Common Failure Diagnosis and Troubleshooting of Motorized Pulley part 2

This article will introduce common failure diagnosis and troubleshooting of motorized pulley to you continuously.

5.Oil leakage of junction box (internal driver).
Troubleshooting method: Check whether the oil level is too high or not. Remove the junction box and tighten the grease seal plug.

6. Big pulley noise.
Troubleshooting method: If noise of newly installed pulley is big, please increase the support rigidity and check the pulley, shaft coupling, motor installation coaxality simultaneously. The method is to remove the pulley from the stand, test run the pulley separately. If the noise becomes smaller, it indicates that the support rigidity needs to be increased.

7.Pulley doesn’t rotate after the backstop pulley is connected to the power supply.
Troubleshooting method: Power supply sequences have errors, the power supply should be disconnected immediately and change the sequences of power supply in order to get the correct sequences of connection.

8. Pulley is reversed when the backstop pulley is disconnected to the power supply.
Troubleshooting method: Check if backstop device is fault or wear and tear.

Common Failure Diagnosis and Troubleshooting of Motorized Pulley(1)

The motorized pulley should be checked regularly and eliminated trouble timely. The common failure and troubleshooting of motorized pulley will be introduced as shown as below:

1.The current of motor is low, and the cylindrical body doesn’t rotate.
Troubleshooting method: Motor should be checked regularly to know whether it is normal or not. If motor is normal, it indicates that there might be broken in coupling pin shaft ,after changing the coupling pin shaft and start the machine to prevent the more severe consequences.

2.Oil leakage in pulley ends and coupling rotating parts.
Troubleshooting method: Tighten the spring coil or replace the grease seal.

3.Oil leakage in end cover.
Troubleshooting method: Tighten the oil plug and change to grease resistant rubber gasket.

4.Oil leakage in the connection parts of cover and cylinder body.
Troubleshooting method: Check whether the connecting bolts are loosen or not and check if the ventilation plug and air outlet are blocked, unclogging it or clean it if it is blocked.

Introduction of spare parts product from Henan pingyuan mining machinery Co., Ltd

Henan pingyuan mining machinery Co., Ltd provides various types of spare parts which are conveyor roller, ultra high molecular polyethylene roller, conveyor pulley, conveyor rainproof cover, vibration motor and screw conveyor part.

Conveyor Roller

Belt conveyor roller is an important part of belt conveyor. It accounts for a total cost of 35% of a belt conveyor, suffered more than 70% of the resistance. So the quality of roller is particularly important.
The role of roller is to support the belt conveyor and the weight of material. Roller must be flexible and reliable operation. Although the roller in the belt conveyor is a small part, structure is not complicated, it is not easy to produce high-quality roller. The conveyor rollers of our company are well accepted by the customers for their higher quality, reasonable price and good service.

Ultra High Molecular Polyethylene Roller

Ultra high molecular polyethylene roller is an advanced product which is to substitute stainless roller, which has some disadvantages such as heavy, easy to be eroded, easy to stick with transporting material, high static electricity and others. it includes ultrahigh molecular polyethylene pipe which produced by high technology as its body, bearing seat and seal are fully rubber material made by one-time. Then, they are sealed with three layer of water-proof and dust-proof installation via labyrinth and contact method

Conveyor Pulley

Conveyor pulley is a mechanical device which stays at two ends of belt machine, guides the belt running, and changes the belt direction and tensions the belt.
Types: driving pulley; bend pulley; coating pulley (includes vulcanized pulleys and cold adhesive pulleys).
The type of rubber surface could be flat, herringbone and rhombic.

Conveyor Rainproof Cover

Conveyor rainproof cover is made by color steel plate.It is used to protect transported material, conveyor belting, idlers and structure from rain, wind, dust during transportation and reducing material loss.Conveyor cover makes operation and transportation safe and reliable,it also plays an important role to purify the environment.

Vibration Motor

Vibration motor is the general exciting vibration source of all kinds of vibrating machines such as vibrating screen, vibrating feeder, vibrating conveyor, vibrating flask shaker, vibrating crusher, vibrating molding machine, vibrating sand mixer, vibrating buffing machine, block-proof device, vibrating test-bed, etc.
