A device fitted with a hinged collar and bowsprings to keep the casing or liner in the center of the wellbore to help ensure efficient placement of a cement sheath around the casing string.
It is being lowered into the hole after drilling has reached total depth and the drill string withdrawn. This allows the casing string to be cemented to the borehole without any 'thin' cement areas.

The basic principle of the hydrocyclone is to separate the two-phase or multi-phase mixture of liquid-liquid, liquid-solid, liquid-gas and so on with a certain density difference under the action of centrifugal force. The mixed liquid is tangentially flowed into the cyclone with a certain pressure, and a high-speed rotating flow field is generated in the cylindrical cavity. The high density components in the mixture under the action of the swirling flow at the same time along the axial downward movement along the radial outward movement in the reach of the cone down along the wall along the wall, and from the bottom outlet, thus forming The small vortex component moves toward the central axis and forms an upwardly moving internal vortex in the center of the axis, and then is discharged from the overflow port, thus achieving the purpose of two-phase separation. Polyurethane characteristics: 1, the hardness range is wide, and the elongation and elasticity of the rubber are still under high hardness. The hardness range of polyurethane board is Shao A10-D80. 2, high strength. In rubber hardness under their tensile strength, tear strength and bearing capacity rubber is much higher than general. Under the high hardness the impact strength and flexural strength and is much higher than that of plastic. 3, wear resistance. The wear resistance is very good, about 3-5 times of the rubber. 4, oil resistance. Polyurethane board is a strong polar polymer, and the affinity of non polar mineral oil, in fuel oil and mechanical oil is almost no corrosion. 5, good resistance to oxygen and ozone. 6, excellent absorption performance, can be used to reduce the vibration, buffer effect. In the mold manufacturing industry, alternative rubber and spring. 7, it has good low temperature performance. 8, radiation resistance, high energy - ray properties of the polyurethane, the use of the 10-10 radiation dose is still satisfactory. 9, have good mechanical processing performance. (car, milling, grinding, drilling can be) Application: widely used in machinery, transportation, oil, mining, construction, textile, sports and other fields. The company to undertake a variety of specifications of the size of polyurethane products custom processing.
