Pull Cord Switch on Belt Conveyor

Do you Know Installation and Adjustment of Pull Cord Switch on Belt Conveyor

Pull Cord Switch is commonly known as "emergency stop switch". When the belt conveyor need downtime, Pull cord switch action will stop the conveyor. Pull cord switch can be divided into manual reset and automatic reset. Automatic reset: after action, it can automatically return to the initial position, may lead to error start. Manual reset: after action, the self-locking device can maintain the operating position, it need to manually reset handle to make its return to the initial position.

Pull Cord Switch should be installed on both sides of the conveyor where has a maintenance channel, installation position should ensure that the maintenance person operates conveniently in the event of an emergency.

1.Pull Cord Switch is fixed on the rack.

2.The distance of the two switches on one side is about 50 m, the two switches are connected by the diameter 4mm of wirerope, elastic should be moderate.

3.To reduce the influence of the weight of wire rope on switches, we install supporting ring on the frame every 3 m to support the steel wire rope.

4.The other end of the rope is in tension spring (with rope buckle), In a way not affecting the normal use, using tightener to pull the rope tension on both sides, and to ensure that tension is balanced on both sides.

(Note: The climbing section of the conveyor, should try to shorten the Switch spacing distance and the pull rope length.)

Pay Attention to the Unbalance Motor Vibration Phenomenon of Vibration Table

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.

PK Engineering Suggests Daily Care and Maintenance of Motorized Pulley

PK Engineering Suggests Daily Care and Maintenance of Motorized Pulley

Are you worried about maintaining and repairing motorized pulley during belt conveyoroperation? We are sure the following solution in four aspects will be a big help :

1. In order to create a good situation for normal operation, surrounding environment, fastening bolts, oil leakage, the cable should be checked before each start-up.

2. Start up the new pulley with inching running, then it will become normal gradually, machine vibration, noise, and temperature heating of each operating component should be checked after running for 10 minutes.

3. If oil leakage occurs to motorized pulley, two parts should be checked : one is oil seal, check it whether has wear and tear or deformation phenomenon, if any, please replace the cage oil seal timely; the other one is that the outlet mustn’t be blocked, if there is any blockage, the deposition of dust, grease and sundries shall be removed as soon as possible to ensure smooth access.

4. Regulation of the oil level height is one of the conditions to ensure the normal operation,so please check the oil level regularly.

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.
