The vibration of the vibrating screen motor is a common fault in the use of the vibrating screen. What causes the fault to occur? The manufacturer of the Dalan oil pump motor tells you the main causes of the vibration of the vibrating screen motor and the precautions are as follows: As shown: 1. Installation problem 1 The vibration motor is equipped with heavier eccentric blocks at both ends. For vertical or inclined installation, the bearing axial direction must bear the gravity of the eccentric block. 2 If there is no special device in the vibration motor, it will have a bad influence on the bearing, thus shortening the service life. Precautions: 1 Select vertical vibration motor; 2 Try to avoid vertical or inclined installation. 2. Adjustment problem of eccentric block When adjusting the eccentric block, the direction of the eccentric block at both ends is reversed, so that the vibration motor generates a space torque, so that the vibration motor works in an abnormal state, thereby causing burnout. Precautionary measures: When adjusting the eccentric block, it is necessary to pay attention to its symmetry, that is, the eccentric blocks at both ends should correspond to each other, or the center of gravity of the eccentric blocks at both ends should be parallel to the axis of rotation and cannot be in a different state. 3. Looseness of anchor bolts 1 Due to the special structure of the vibration motor itself, the exciting force generated by the eccentric blocks at both ends must impact the anchor bolts twice per minute; 2 due to the vibration of the vibration motor itself, Therefore, the ground bolt is very easy to loosen. Once a bolt is loose, it will cause other bolts to loosen or even break in a short period of time, thus burning the motor. Precautionary measures: 1 Reinforce the anchor bolts frequently; 2 Increase the anti-loose device; 3 Ensure good contact between the ground surface and the motor floor, so that several anchor bolts are evenly stressed. 4, the sealing problem of the protective cover Because the working environment of the vibration motor is very harsh, dust is large, if the protective cover is not tightly sealed, it is easy to enter the dust, causing the friction operation of the eccentric block, thereby burning the motor. Precautions: 1 Increase the seal of the protective cover; 2 Clean the dust inside the protective cover frequently. 5, heat dissipation problem Vibration motor without fan can dissipate heat, relying on natural cooling, plus the working environment is very harsh, dust is very large, dust is easy to accumulate on the motor surface, causing the internal temperature is too high, burning the motor. Precautions: 1 Always remove the dust on the surface of the vibrating screen vibration motor to make it work under good conditions. 2 During the design process, the surface of the vibrating motor should be as smooth as possible, so that the dust is not easy to accumulate. If it is working in a dusty environment, Consideration should be given to subtracting the heat sink from the surface of the casing. Because the heat dissipation ribs not only fail to heat up, but also easily cause dust to accumulate, hindering the heat dissipation of the motor. 6. Ambient temperature The vibration motor and equipment are rigidly connected. It can also be said to be a whole. If the temperature of the material conveyed by the equipment is too high, it will easily cause the temperature of the ground and the casing of the vibration motor to increase, which will cause heat dissipation and burn the motor. Precautionary measures: 1 Keep the vibration motor away from high temperature materials as far as possible without affecting the work of the equipment; 2 Find ways to reduce the temperature of the material. ----- Responsible Editor: Dalan Oil Pump Motor 02- Purchasing Consultant Copyright http:/(Dalan Motor) Reprint, please indicate the source http://news.chinawj.com.cn
FHM fence factory provides a variety of Chain Link Fence to support your selling.You could have a multiple choice here.
According to the surface cover chain link fence is divided into Galvanized Chain Link Fence and Vinyl Coated Chain Link Fence. As the low cost and easy installation Vinyl Coated Chain Link Fence is used in many areas which covers road, railway, high-way and other fence facilities.
Chain Link Fence is also be called diamond fence because of the diamond opening. The selvage has two types which are knuckle and Twist type.
