How to deal with oil field valve leakage problem

Valve is an important part of the oilfield facilities, especially for gathering and conveying system, the valve is more widely used. At present, the oilfield enters the period of high water cut development, and the corrosion caused by high water content on the valve is also increasingly serious. Valve often see the phenomenon of leakage. Tips to deal with oil field valve leakage problems: 1, the valve packing sealing method to seal, packing seal and other sealing methods combined, the oil seal into the step for the interference fit. 2, Throughout the assembly process, leave some space in the stuffing box, add a compression spring between the lower part of the oil seal and the remaining packing, so that the compression spring has an upward force on the oil seal, and there is a downward force on the packing force. 3. Add a circular asbestos cushion between the packing gland and stuffing box. Finally, the gland and packing box's surface are closely fitted by the bolts of packing gland. Through a period of popularization and application, in the production to eliminate the leakage phenomenon, extending the maintenance cycle, reducing the labor intensity of workers, to avoid the occurrence of crude oil pollution.

Drive Shaft Bearings

APPLICATION FEATURES

1. Environment:The bearing is located in the lower part of the chassis, normally working in a dusty and mud splash environment, so it is with high requirement of bearing sealing performance. Working in outside, from low temperature -40 ℃ to high temperature 100℃;

2. Rotating speed: Highest is 3000rpm;

3. Loading: Besides to bear the weight of the main rotating axis, also need to bear the uncertain axial load;

4. Eccentric Oblique angle:Bearing is used with propeller shaft(or drive shaft), need consider to compensate the installation error of the shaft, and the displacement caused by the engine vibration and frame deformation, so the oblique angle of bearing are key factor to be paid attention during bearing design.
