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.

Five Maintenance Tips for Belt Conveyor Roller

Belt conveyor roller is an important part for belt conveyor. It accounts for 35% of a belt conveyor total cost and bears more than 70% of the resistance. So the maintenance of conveyor roller is particularly important. Today PK Machinery will share some maintenance tips with you:

1. Generally speaking, the roller normal service life is more than 20000 h and it doesn’t need maintain. But according to application place and load capacity, we should formulate a maintenance date correspondingly, as well as cleaning, adding grease and maintenance etc. For the rollers which with abnormal sound or rollers don’t rotate, please to replace timely.

2. When replace the bearing, keep the bearing opening outward, spare proper clearance when put the bearings into the roller.

3. The labyrinth seals should adopt original accessories, put the seals into the roller respectively when assembly.

 

4. During operation, the rollers should be protected from heavy items hitting the tube.

5. In order to ensure the roller sealing performance and using performance, free disassembly roller is prohibited.
