KOSUN KD series slurry treatment unit is mainly used to purify mud

Slurry pressurized balance shield: a partition plate is set at the front of the mechanical shield, and a mud-water tank is formed between it and the cutter head. The stability of the excavation surface is to send the mud into the mud-water tank, and use the mud on the excavation surface. An impermeable mud film is formed, and the water pressure is maintained by the tension of the mud film to balance the earth pressure and water pressure acting on the excavation surface. The excavated soil and sand are transported to the ground in the form of mud, separated by slurry treatment equipment, and the quality of the separated mud water is adjusted before being transported to the excavation surface. According to the difference in the structure of the mud tank and the control method of the mud pres

The role of slurry separation equipment in the construction of urban construction projects

In the construction of urban construction pile foundation engineering, the pile foundation construction mud plays an important role in balancing the formation pressure and protecting the stability of the hole wall, but the disposal of excess mud and final waste mud directly affects the progress, quality, civilized construction and environmental protection of the site project. In many other aspects, it has always been a problem that has plagued engineering construction. The conventional disposal method is to transport the waste mud by closed tank trucks to the cofferdam in the designated area in the suburbs for accumulation and natural drying, or transport it to the wharf, and then transfer it to the designated area at sea for discharge. The pile foundation projects constructed in the centr

Equipment treatment effect of KOSUN geothermal well mud solids control treatment system

Geothermal well mud refers to the mud used for geothermal well drilling. The most prominent feature of geothermal well mud is high temperature resistance. High temperature will cause the mud clay to disperse, thicken, and even solidify due to high temperature, which will destroy the mud performance and cause the well wall to collapse, wellbore overrun, diameter reduction, drill bit mud bag, plugging closed production layers, etc. Therefore, the mud treatment of geothermal wells is a key problem in geothermal drilling. The geothermal well mud treatment process must be equipped with corresponding professional solid phase control equipment. The selection of geothermal well mud is mainly determined according to the specific temperature of the geothermal well. Geothermal well mud has the follow

Coalbed methane drilling mud treatment requires KOSUN solids control systems

In the exploration and development of coalbed methane, drilling is a necessary means. Coal seams have the characteristics of low porosity, low permeability and low reservoir pressure, and the well type of coal seam well can greatly increase the contact area between the wellbore and the coal seam. Coalbed methane recovery factor is therefore commonly used. Coal seam drilling and coal seam drilling encounter a large area, and the coal seam fissure system is developed, mechanical strength is weak, and stress sensitivity is strong, so it is easy to encounter problems in the process of drilling. Difficulties such as easy pollution. Therefore, it is necessary to harmlessly treat the drilling fluid and mud in the process of coal seam drilling. KOSUN solids control systems are required for CBM dri
