Oil well Check valve was successfully developed
Recently, SK-1 type oil pump Check Valve on the ground in the Shengli Oilfield four wins to adopt the successful development of a mine. The check valve can effectively avoid the problem of gas welding.
The device has a sheng from the Shengli Oilfield four ore mining engineering technology research station group after more than 3 months from the development of the non-return valve installed in sets of internal grease nipple, where Dole used the ball in the hemisphere, linking the back of the rod centralizer, to avoid the spring Stretch-induced lower lateral spheres have a sphere of no return, at the same time as the valve chamber volume increased flow area increases, reducing the flow resistance and improve the efficiency of the pumping system to meet the specifications for a variety of pumps Drive Different needs.
The device is small and light, used to connect Sikou, replacement, a person 10 minutes to complete, thus avoiding the need to replace the original series, such as the use of Dianqi Han problem, reduce the workload and improve the security and reliability, reduced Yield loss. At present, the check valve on the ground in the mine more wells were installed on-site testing, has achieved remarkable results.
