As environmental protection requirements on domestic oilfields are becoming more stringent, zero discharge drilling waste projects have skyrocketed in recent years. By virtue of years of experience in overseas drilling waste system equipment, KOSUN ha
KOSUN KD series slurry separation system mainly consists of scalping shaker module, desanding module and desilting module. As a pre-screener, the scalping shaker can remove coarse particles from mud. The desanding module is equipped with desander (primary cyclones) and fine-mesh shaker and mainly removes granulated sand. The desilting module is equipped with desilter (secondary cyclones) and can conduct a fine separation selectively according to the field needs of customers. Mud closed-loop circulating purification mode and lower water content in slags help reduce the environmental pollution. Equipment parts of the system are of anti-corrosion and wear-resistance, long service life and low failure rate, and the system can be suitable for various severe working conditions. Simple and useful
Slurry pressurized balanced shield: means that a partition is set in front of mechanical shield to form a slurry compartment between the partition and the cutterhead. The stability of excavation face is achieved in this way: feed mud into the slurry compartment, form a waterproof mud film with mud on the excavation face, and maintain water pressure by the tension of mud film to balance soil pressure and water pressure on the excavation face. The soil and sand excavated are transported to the ground in the form of mud and are separated by slurry treatment equipment . The separated slurry is adjusted in specific gravity and then transported to the excavation face. After the engineering mud is treated by KOSUN waste treatment system, the dried solids can be up to the standard of landfilling o
The single screw pump has been extensively applied in developed countries, which is often called as mono pump in foreign countries and known as eccentric rotary pump in Germany. For its excellent performance, the pump is rapidly used in a larger application range at home in recent years. The most striking features of the pump are strong adaptability to media, stable flow rate, low pressure fluctuation and high self-priming capacity, which cannot be replaced by any other pumps. The single screw pump is a late-model pump based on the working principle of return mesh volume. Its main working elements are eccentric screw (rotor) and fixed lining (stator). These two elements form into separate sealed chambers due to their special geometries. The media are driven to uniformly flow along the axia
Single screw pump is widely used in the oil drilling industry. Read More »
In urban subway construction, TBM has become one of the main choices for tunnel construction. The large amount of waste residue generated in the shield tunneling construction has brought many challenges to the urban environment. The dewatering, transportation, and landfill of residue will have a large adverse impact on the environment. As a kind of urban mineral resources, residue will consume a lot of land resources in landfilling. If the residue is recycled to be used as synchronous injecting paste material, raw material of ecological brick, roadbed filling, etc., it will effectively improve the ecological and environmental protection function of subway construction. However, at present, the recycling rate of TBM residue in China is very limited, and a further research on residue applica

LS2752 double-deck linear shale shaker can achieve four treatment effects: 1. Can be used as a two-stage shale shaker; 2. The lower screen can be used as a shale shaker and the upper screen as an underflow shaker of desander ; 3. The lower screen can be used as a shale shaker and the upper screen as an underflow shaker of desilter ; 4. The lower screen can be used as an underflow shaker of desander and the upper screen as an underflow shaker of desilter. Thus, it can be used under various operating conditions for different treatment effects, which can achieve multiple functions, greatly reduce cost and save installation space. Recycling process: centrifugal pump transports mud from mud pit into logging tank of shale shaker. After being treated by coarse screen of shale shaker, large cuttin

KOSUN MD210 mud cleaner is the second and third-stages solids control equipment in the drilling fluid solids control system, and further separates fine sand and other impurities contained in the mud treated by the shale shaker , facilitating mud to enter the fourth stage separation equipment. MD210 Cleaner can be used separately, and its underflow shale shaker can also be used as standby equipment in parallel with the first-stage solid control shale shaker, and our company can provide corresponding diversion manifold. The LS703 underflow shale shaker of MD210 Cleaner is a high frequency linear-motion vibrating screen machine, equipped with three screen panels and two vibrating motors, and offering a choice of manually adjusting screen frame angle while drilling (AWD). When LS703 shale shak

Mud solidification system is used to treat cuttings or drilling waste, which is developed to treat cuttings from oilfield drilling, trenchless construction, municipal engineering and other fields. When the mud solidification system runs, mechanical friction and wear will occur. About the maintenance of mud solidification equipment , you need to know the following: 1. Vibrating motors , screw conveyors , driving motors of agitating and solidification equipment, etc. should be regularly added with lubricating oil, which can effectively protect solidification devices, reduce mechanical friction, prevent mechanical wear, dust and metal corrosion, and avoid unnecessary friction and wear of solidification equipment. 2. Regularly check the lubricating oil consumption of the agitator and screw con
