Last week, Xi ‘a KOSUN production of the ZJ70 rig solid control system was successfully sent to the domestic rig factory for supporting commissioning, this cooperation is the Ukrainian customer, the final use of the equipment in Turkmenistan, mainly for the treatment of local oil drilling mud.
The ZJ70 rig solid control system is composed of a solid control tank, water tank, rain shelter, vibrating screen, vacuum degator, cleaner, variable frequency centrifuge, liquid supply pump, sand pump, mixing weight leakage, mud agitator, sitting room and other equipment to form a five-level solid control system, which can classify drilling mud. Also, it can weigh, mix, and stir mud. The equipment is simple to operate and convenient to maintain. The operating cost is effectively reduced and the overall drilling efficiency is improved. To facilitate the successful delivery of the project, the Kesun team works day and night to carry out production work, from the selection of equipment to production, and then to the internal assembly and commissioning, each link is strictly controlled to ensure that we provide customers with high-quality products. As a professional manufacturer of solid-liquid separation equipment, KOSUN has perfect experience in research and development and production of separation equipment for mud, drilling cuttings, sludge, and other materials, and provides customized transportation equipment solutions according to the characteristics of site construction, focusing on providing customers with solid waste reduction, harmless and resource services. The company has been adhering to the “quality first, customer first” business philosophy, constantly innovating and improving products and product quality and performance to meet customers’ changing needs.
Drilling fluid vibrating screen in the work, may lead to various failures of the vibrating screen, the following brief introduction to the causes of various failures and solutions:
Abnormal material flow on the screen surface of drilling fluid vibrating screen. First, the stiffness of the screen box is insufficient, there is a critical frequency, and the coupling bolts have been shaken loose, or even to the extent of full shaken loose, that is, fastening. Second, the horizontal level of the screen box is not found, from the support base of the supporting foot spring or the spring itself to find problems, change the spring or change the size of the support, and may be caused by the screen surface network damage, as long as the screen can be replaced. If the stiffness of the screen box is insufficient and the horizontal level is not found correctly, the beam will be broken, and the material flow will be abnormal if it is still running. There may be improper operation, that is, the feed is extremely unbalanced is also one of the reasons.
2, drilling fluid vibrating screen can not start or the amplitude is too small, should check the electrical barrier-free, vibration motor is damaged, or the components in the line are damaged, whether the voltage is insufficient, there is no problem in these three aspects, and then from the mechanical check, the vibrating screen screen surface of the material is accumulated too much, if it is removed. Whether the coupling bolt on the shaker falls off, whether the grease thickens and clumps, at this time, the shaker can be cleaned and repaired, and then the position of the eccentric shaft weighting block or the auxiliary eccentric block can be appropriately adjusted.
3, drilling fluid vibrating screen side plate cracks, beam fracture, structural damage, such a situation will not suddenly, is in the critical frequency of working time is too long, such as a large number of tight side plate high-strength bolts loose, spring serious deformation of the left and right height difference is very much, there may also be eccentric block each weight error is too large, causing damage to the structural parts, wall plate cracks, even beam fracture, In addition to replacing the damaged parts and tightening the bolts, when repairing the cracks in the wall panel, two 6mm holes must be punched in the second head to prevent the extension of the cracks. It should be noted that several air holes should be punched in the strengthening plate when filling the strengthening plate.
4, drilling fluid vibrating screen rotation is slow, bearing heat, this situation, indicating that the usual maintenance is not up to date, bearing lack of grease, if it is new grease, it is the quality of the oil or added too full, inferior oil makes the bearing block the maze seal plug, so the quality of grease is very important.
5, drilling fluid vibrating screen screening quality is poor, the reason is that the responsibility of improper operation is more, may be blocked mesh, the increase of fine particles in the sieve material and the increase of water, so that the sieve layer is too thick, uneven feeding and so on. It is possible that the two sides of the screen are not tight, if the shaft is eccentric vibration, the belt may be weak in the drag, the belt is too loose, and the mechanical problems are handled, and you can reverse rotate for a period of time to improve the screening quality.
6, the circular vibrating screen noise is too large, may be bearing damage, bolt loose, cross beam break and spring damage, in addition to the bolt can be tightened, the other three conditions need to replace parts.
