Several common problems of drilling shaker screens
Drilling shaker screens are a screening equipment that can be classified, dewatered, deslimed, desorbed, and sorted. It uses the vibration of the screen body to loosen, layer, and screen the materials to achieve the purpose of material separation. The screening effect of the vibrating screen not only has a great influence on the value of the product, but also has a direct influence on the efficiency of the next operation.
In daily production, drilling shaker screens will encounter various problems, such as bearing heating, component wear, breakage and screen hole blockage, wear, etc. These are the main reasons that affect the screening efficiency, so in order to improve the efficiency To provide guarantee for follow-up operations, solving these common problems is the key.
Under normal circumstances, during drilling shaker screens and normal operation, the bearing temperature should be kept within the range of 35~60℃. If the temperature exceeds this value, the temperature needs to be reduced. The main reasons for the high bearing temperature are as follows:
1. The bearing radial clearance is too small
Drilling shaker screens If the radial clearance of the bearing is too small, it will cause the bearing to wear and heat up, mainly because the bearing is carrying a large load, the frequency is high, and the load is constantly changing.
Solution: It is recommended that the bearing adopts a large clearance. If it is a bearing with a normal clearance, the outer ring of the bearing can be ground to a large clearance.
2. The bearing gland is too tight
There needs to be a certain gap between the gland of drilling shaker screens and the outer ring of the bearing, so as to ensure the normal heat dissipation of the bearing and a certain amount of axial movement.
Solution: If the top of the bearing gland is too tight, it can be adjusted by the gasket between the end cover and the bearing seat, and it can be adjusted to a suitable gap.
3. Too much or too little bearing oil, polluted or inconsistent oil quality
The lubrication system can ensure the normal operation of the drilling shaker screens bearing, prevent foreign matter from intruding and sealing, and can also remove frictional heat, reduce friction and wear, and prevent the bearing from heating up too high. Therefore, during production, we must ensure the amount of vibrating screen bearing grease And quality.
Solution: The bearing box needs to be refueled regularly according to the equipment usage requirements to avoid too much or too little oil. If there is a problem with the oil quality, it needs to be cleaned, replaced and sealed in time.
When solving these problems, in addition to finding and solving problems in time, you also need to pay attention to purchase and model selection. Try to choose reliable and reputable manufacturers, so as to effectively improve the operating efficiency of drilling shaker screens.
